The Peugeot 405 model range was introduced into the UK inJanuary 1988 in Saloon form only.

Available with 1.6, 1.8, 1.9 and 2.0 engines, all models have front-wheel-drive with all round independent suspension.

Automatic transmission models were introduced in April 1988.In July 1988 came the sporty Mi 16 version with its 1.9 litre double

overhead cam, 16-valve engine, uprated gearbox, suspension and anABS braking system to match its power.

Estate car versions were introduced in October 1988.From 1991, engines equipped with catalytic converters were

progressively introduced, to meet the more stringent exhaust gasemission regulations.

Since its introduction, the 405 range has continually beendeveloped. All models have a high trim level, which is verycomprehensive in the upper model range.

For the home mechanic, the Peugeot 405 is a straightforwardvehicle to maintain and repair since design features have beenincorporated to reduce the actual cost of ownership to a minimum, andmost of the items requiring frequent attention are easily accessible.

Your Peugeot 405 ManualThe aim of this manual is to help you get the best value from your

vehicle. It can do so in several ways. It can help you decide what workmust be done (even should you choose to get it done by a garage),provide information on routine maintenance and servicing, and give alogical course of action and diagnosis when random faults occur.However, it is hoped that you will use the manual by tackling the workyourself. On simpler jobs, it may even be quicker than booking the carinto a garage and going there twice, to leave and collect it. Perhapsmost important, a lot of money can be saved by avoiding the costs agarage must charge to cover its labour and overheads.

The manual has drawings and descriptions to show the function ofthe various components, so that their layout can be understood. Thenthe tasks are described and photographed in a clear step-by-stepsequence.

Safety First! 0•5

Working on your car can be dangerous.This page shows just some of the potentialrisks and hazards, with the aim of creating asafety-conscious attitude.

General hazardsScalding• Don’t remove the radiator or expansiontank cap while the engine is hot.• Engine oil, automatic transmission fluid orpower steering fluid may also be dangerouslyhot if the engine has recently been running.

Burning• Beware of burns from the exhaust systemand from any part of the engine. Brake discsand drums can also be extremely hotimmediately after use.

Crushing• When working under or neara raised vehicle,alwayssupplement thejack with axlestands, or usedrive-onramps.Neverventureunder a car whichis only supported by a jack.• Take care if loosening or tightening high-torque nuts when the vehicle is on stands.Initial loosening and final tightening shouldbe done with the wheels on the ground.

Fire• Fuel is highly flammable; fuel vapour isexplosive. • Don’t let fuel spill onto a hot engine. • Do not smoke or allow naked lights(including pilot lights) anywhere near avehicle being worked on. Also beware ofcreating sparks (electrically or by use of tools).• Fuel vapour is heavier than air, so don’twork on the fuel system with the vehicle overan inspection pit.• Another cause of fire is an electricaloverload or short-circuit. Take care whenrepairing or modifying the vehicle wiring.• Keep a fire extinguisher handy, of a typesuitable for use on fuel and electrical fires.

Electric shock • Ignition HTvoltage can bedangerous,especially topeople with heartproblems or apacemaker. Don’twork on or near theignition system withthe engine running orthe ignition switched on.

• Mains voltage is also dangerous. Makesure that any mains-operated equipment iscorrectly earthed. Mains power points shouldbe protected by a residual current device(RCD) circuit breaker.

Fume or gas intoxication • Exhaust fumes arepoisonous; they oftencontain carbonmonoxide, which israpidly fatal if inhaled.Never run theengine in aconfined spacesuch as a garagewith the doors shut.• Fuel vapour is alsopoisonous, as are the vapours from somecleaning solvents and paint thinners.

Poisonous or irritant substances• Avoid skin contact with battery acid andwith any fuel, fluid or lubricant, especiallyantifreeze, brake hydraulic fluid and Dieselfuel. Don’t syphon them by mouth. If such asubstance is swallowed or gets into the eyes,seek medical advice.• Prolonged contact with used engine oil cancause skin cancer. Wear gloves or use abarrier cream if necessary. Change out of oil-soaked clothes and do not keep oily rags inyour pocket.• Air conditioning refrigerant forms apoisonous gas if exposed to a naked flame(including a cigarette). It can also cause skinburns on contact.

Asbestos• Asbestos dust can cause cancer if inhaledor swallowed. Asbestos may be found ingaskets and in brake and clutch linings.When dealing with such components it issafest to assume that they contain asbestos.

Special hazardsHydrofluoric acid• This extremely corrosive acid is formedwhen certain types of synthetic rubber, foundin some O-rings, oil seals, fuel hoses etc, areexposed to temperatures above 4000C. Therubber changes into a charred or stickysubstance containing the acid. Once formed,the acid remains dangerous for years. If itgets onto the skin, it may be necessary toamputate the limb concerned.• When dealing with a vehicle which hassuffered a fire, or with components salvagedfrom such a vehicle, wear protective glovesand discard them after use.

The battery• Batteries contain sulphuric acid, whichattacks clothing, eyes and skin. Take carewhen topping-up or carrying the battery.• The hydrogen gas given off by the batteryis highly explosive. Never cause a spark orallow a naked light nearby. Be careful whenconnecting and disconnecting batterychargers or jump leads.

Air bags• Air bags can cause injury if they go offaccidentally. Take care when removing thesteering wheel and/or facia. Special storageinstructions may apply.

Diesel injection equipment• Diesel injection pumps supply fuel at veryhigh pressure. Take care when working onthe fuel injectors and fuel pipes.

Warning: Never expose the hands,face or any other part of the bodyto injector spray; the fuel can

penetrate the skin with potentially fatalresults.

Remember...DO• Do use eye protection when using powertools, and when working under the vehicle.

• Do wear gloves or use barrier cream toprotect your hands when necessary.

• Do get someone to check periodicallythat all is well when working alone on thevehicle.

• Do keep loose clothing and long hair wellout of the way of moving mechanical parts.

• Do remove rings, wristwatch etc, beforeworking on the vehicle – especially theelectrical system.

• Do ensure that any lifting or jackingequipment has a safe working load ratingadequate for the job.

A few tipsDON’T• Don’t attempt to lift a heavy componentwhich may be beyond your capability – getassistance.

• Don’t rush to finish a job, or takeunverified short cuts.

• Don’t use ill-fitting tools which may slipand cause injury.

• Don’t leave tools or parts lying aroundwhere someone can trip over them. Mopup oil and fuel spills at once.

• Don’t allow children or pets to play in ornear a vehicle being worked on.

0•6 Roadside RepairsThe following pages are intended to help in dealing with

common roadside emergencies and breakdowns. You will findmore detailed fault finding information at the back of themanual, and repair information in the main chapters.

If your car won’t start and the starter motordoesn’t turnM If it’s a model with automatic transmission, make sure the

selector is in ‘P’ or ‘N’.M Open the bonnet and make sure that the battery terminals

are clean and tight.M Switch on the headlights and try to start the engine. If the

headlights go very dim when you’re trying to start, thebattery is probably flat. Get out of trouble by jump starting(see next page) using a friend’s car.

If your car won’t start even though the startermotor turns as normalM Is there fuel in the tank?M Is there moisture on electrical components under the

bonnet? Switch off the ignition, then wipe off any obviousdampness with a dry cloth. Spray a water-repellent aerosolproduct (WD-40 or equivalent) on ignition and fuel systemelectrical connectors like those shown in the photos. Pay special attention to the ignition coil wiring connectorand HT leads. (Note that Diesel engines don’t normallysuffer from damp.)

Check that the spark plug HT leads(where applicable) are securelyconnected by pushing them home.

A The throttle potentiometer wiring plugmay cause problems if not connectedsecurely.

B Check the idle speed stepper motorwiring plug for security.C

Check the security and condition of thebattery connections.D

Check that the ignition coil wiring plug issecure, and spray with water-dispersantif necessary.

ECheck that electrical connections are secure (with the ignition switched off) and spray themwith a water dispersant spray like WD40 if you suspect a problem due to damp

Roadside Repairs 0•7

When jump-starting a car using abooster battery, observe the followingprecautions:

4 Before connecting the boosterbattery, make sure that the ignition isswitched off.

4 Ensure that all electrical equipment(lights, heater, wipers, etc) isswitched off.

4 Make sure that the booster battery isthe same voltage as the dischargedone in the vehicle.

4 If the battery is being jump-startedfrom the battery in another vehicle,the two vehcles MUST NOT TOUCHeach other.

4 Make sure that the transmission is inneutral (or PARK, in the case ofautomatic transmission).

Jump starting will get you outof trouble, but you must correctwhatever made the battery goflat in the first place. There are three possibilities:

1 The battery has been drained byrepeated attempts to start, or by

leaving the lights on.

2 The charging system is not workingproperly (alternator drivebelt slack

or broken, alternator wiring fault oralternator itself faulty).

3 The battery itself is at fault(electrolyte low, or battery worn out).

Connect one end of the red jump lead tothe positive (+) terminal of the flatbattery

Connect the other end of the red lead tothe positive (+) terminal of the boosterbattery.

Connect one end of the black jump leadto the negative (-) terminal of thebooster battery

Connect the other end of the blackjump lead to a bolt or bracket on theengine block, well away from thebattery, on the vehicle to be started.

Make sure that the jump leads will notcome into contact with the fan, drive-belts or other moving parts of theengine.

5

Start the engine using the boosterbattery, then with the engine running atidle speed, disconnect the jump leads inthe reverse order of connection.

Jump starting

In the boot, use the wheel brace toloosen the spare wheel cradle bolt.

0•8 Roadside Repairs

Wheel changingSome of the details shown here will varyaccording to model. For instance, the locationof the spare wheel and jack is not the sameon all cars. However, the basic principlesapply to all vehicles.

M When a puncture occurs, stop as soonas it is safe to do so.

M Park on firm level ground, if possible,and well out of the way of other traffic.

M Use hazard warning lights if necessary.

M If you have one, use a warning triangle toalert other drivers of your presence.

M Apply the handbrake and engage first orreverse gear.

M Chock the wheel diagonally opposite the

one being removed – a couple of largestones will do for this.

M If the ground is soft, use a flat piece ofwood to spread the load under the footof the jack.

Changing the wheel

Preparation

Warning: Do not change a wheel in a situation where you risk being hit byother traffic. On busy roads, try to stop in a lay-by or a gateway. Be wary ofpassing traffic while changing the wheel – it is easy to become distracted bythe job in hand.

Finally...M Remove the wheel chocks.

M Stow the jack and tools in the correct locations in the car.

M Make sure that the spare wheel cradle is properly secured, or it could drop onto the roadwhile driving.

M Check the tyre pressure on the wheel just fitted. If it is low, or if you don’t have a pressuregauge with you, drive slowly to the nearest garage and inflate the tyre to the right pressure.

M Have the damaged tyre or wheel repaired as soon as possible.

Before raising the car, loosen the wheelbolts slightly using the wheelbrace.

Locate the jack head in the jacking pointand use the brace to raise the car untilthe wheel is clear of the ground.

Temporarily place the spare wheel underthe sill as a precaution should the jacktopple.

Use the wheel brace to remove the wheeltrim.

Remove the spare wheel from the cradle.1 2 3

Remove the bolts and remove the wheel.Fit the spare wheel and hand-tighten thebolts. Lower the car, then tighten the

wheel bolts firmly. Have the bolts tightened tothe correct torque at the earliest opportunity.

Roadside Repairs 0•9

When all else fails, you may find yourselfhaving to get a tow home – or of course youmay be helping somebody else. Long-distancerecovery should only be done by a garage orbreakdown service. For shorter distances, DIYtowing using another car is easy enough, butobserve the following points:M Use a proper tow-rope – they are notexpensive. The vehicle being towed mustdisplay an ‘ON TOW’ sign in its rear window.M Always turn the ignition key to the ‘on’position when the vehicle is being towed, so

that the steering lock is released, and that thedirection indicator and brake lights will work.M Only attach the tow-rope to the towingeyes provided.M Before being towed, release the handbrakeand select neutral on the transmission.M Note that greater-than-usual pedalpressure will be required to operate thebrakes, since the vacuum servo unit is onlyoperational with the engine running.M On models with power steering, greater-than-usual steering effort will also be required.

M The driver of the car being towed mustkeep the tow-rope taut at all times to avoidsnatching.M Make sure that both drivers know the routebefore setting off.M Only drive at moderate speeds and keepthe distance towed to a minimum. Drivesmoothly and allow plenty of time for slowingdown at junctions.M On models with automatic transmission,special precautions apply. If in doubt, do nottow, or transmission damage may result.

Towing

Puddles on the garage floor or drive, orobvious wetness under the bonnet or underneath the car, suggest a leak that needsinvestigating. It can sometimes be difficult todecide where the leak is coming from,especially if the engine bay is very dirtyalready. Leaking oil or fluid can also be blownrearwards by the passage of air under the car,giving a false impression of where theproblem lies.

Warning: Most automotive oilsand fluids are poisonous. Washthem off skin, and change out ofcontaminated clothing, withoutdelay.

Identifying leaksThe smell of a fluid leakingfrom the car may provide aclue to what’s leaking. Somefluids are distinctively

coloured. It may help to clean the carcarefully and to park it over some cleanpaper overnight as an aid to locating thesource of the leak.Remember that some leaks may onlyoccur while the engine is running.

Sump oil Gearbox oil

Brake fluid Power steering fluid

Oil from filter

Antifreeze

Engine oil may leak from the drain plug... ...or from the base of the oil filter.

Leaking antifreeze often leaves a crystallinedeposit like this.

Gearbox oil can leak from the seals at theinboard ends of the driveshafts.

A leak occurring at a wheel is almostcertainly brake fluid.

Power steering fluid may leak from the pipeconnectors on the steering rack.

0•10 Weekly Checks

There are some very simple checks whichneed only take a few minutes to carry out, butwhich could save you a lot of inconvenienceand expense.

These "Weekly checks" require no great skillor special tools, and the small amount of timethey take to perform could prove to be verywell spent.

M Keeping an eye on tyre condition andpressures, will not only help to stop themwearing out prematurely, but could also saveyour life.

M Many breakdowns are caused by electricalproblems. Battery-related faults are particularlycommon, and a quick check on a regular basiswill often prevent the majority of these.

M If your car develops a brake fluid leak, thefirst time you might know about it is whenyour brakes don't work properly. Checkingthe level regularly will give advance warning ofthis kind of problem.M If the oil or coolant levels run low, the costof repairing any engine damage will be fargreater than fixing the leak, for example.

Warning: DO NOT attempt toremove the expansion tankpressure cap when the engineis hot, as there is a very greatrisk of scalding. Do not leaveopen containers of coolant

about, as it is poisonous.

Car Carel With a sealed-type cooling system,adding coolant should not be necessary on aregular basis. If frequent topping-up isrequired, it is likely there is a leak. Check theradiator, all hoses and joint faces for signs ofstaining or wetness, and rectify as necessary.

l It is important that antifreeze is used inthe cooling system all year round, not justduring the winter months. Don’t top-up withwater alone, as the antifreeze will becometoo diluted.

Coolant level

The coolant level varies with enginetemperature. When cold, the coolantlevel should be on the “MAXI” mark

(arrowed). When the engine is hot, the levelmay rise slightly above the “MAXI” mark.

If topping up is necessary, wait until theengine is cold. Unscrew the expansiontank cap to the first stop, to release any

pressure present in the system. Push the capdown, turn to the second stop, and remove it.

Add a mixture of water and antifreezethrough the expansion tank filler neck,until the coolant level is up to the “MAXI”

level mark. Refit the cap, turning it clockwiseas far as it will go to secure.

Engine oil levelBefore you start4 Make sure your car is on level ground.4 Check the oil level before the car is driven,or at least 5 minutes after the engine has beenswitched off.

The correct oilModern engines place great demands on theiroil. It is very important that the correct oil foryour car is used (See “Lubricants, fluids andtyre pressures”).

Car Carel If you have to add oil frequently, youshould check whether you have any oil leaks.Place some clean paper under the carovernight, and check for stains in the morning.If there are no leaks, the engine may beburning oil (see “Fault Finding”).

l Always maintain the level between theupper and lower dipstick marks (see photo 3).If the level is too low severe engine damagemay occur. Oil seal failure may result if theengine is overfilled by adding too much oil.

If the oil is checkedimmediately after driving thevehicle, some of the oil willremain in the upper engine

components, resulting in an inaccuratereading on the dipstick!

The dipstick top is often brightly colouredfor easy identification (see “Underbonnetcheck points” on pages 0•10 and 0•11

for exact location). Withdraw the dipstick.

Using a clean rag or paper towel removeall oil from the dipstick. Insert the cleandipstick into the tube as far as it will go,

then withdraw it again.

Note the oil level on the end of thedipstick, which should be between theupper ("MAX") mark and lower ("MIN")

mark. Approximately 1.0 litre of oil will raisethe level from the lower mark to the uppermark.

Oil is added through the filler cap.Unscrew the cap and top-up the level; afunnel may help to reduce spillage. Add

the oil slowly, checking the level on the dipstickoften. Don’t overfill (see “Car Care” left).

Brake fluid levelWarning: Brake fluid can harmyour eyes and damage paintedsurfaces, so use extremecaution when handling andpouring it.

Warning: Do not use fluid that has beenstanding open for some time, as it absorbsmoisture from the air, which can cause adangerous loss of braking effectiveness.

Before you start:4 Park the vehicle on level ground.

4 On models with ABS (anti-lock brakes),switch the ignition off and pump the brakepedal at least 20 times or until the pedalfeels hard. Open the bonnet. Switch onthe ignition: the hydraulic unit pump willbe heard running. Wait until the pumpstops, then switch off the ignition.

Safety First!l If the reservoir requires repeated topping-up this is an indication of a fluid leaksomewhere in the system, which should beinvestigated immediately. l If a leak is suspected, the car should notbe driven until the braking system has beenchecked. Never take any risks where brakesare concerned.

The fluid level in the reservoirwill drop slightly as the brakepads wear down, but thefluid level must never be

allowed to drop below the “MIN” mark.

The “MAX” (A) and “DANGER” (B) marksare indicated on the side of the reservoir,which is located in the scuttle at the reardriver’s side of the engine compartment.

The fluid level must be kept between thesetwo marks.

1 If topping-up is necessary, first wipe thearea around the filler cap with a clean ragbefore removing the cap. Check the fluid

already in the reservoir - the system should bedrained and refilled if dirt is seen in the fluid(see Chapter 9 for details).

2

Carefully add fluid, avoiding spilling it onsurrounding paintwork. Use only thespecified hydraulic fluid; mixing different

types of fluid can cause damage to thesystem and/or a loss of braking effectiveness.After filling to the correct level, refit the capsecurely. Wipe off any spilt fluid.

3 Check the operation of the low fluid levelwarning light. Chock the roadwheels,release the handbrake, and switch on the

ignition. Ask an assistant to press the button ontop of the reservoir. The brake fluid level/handbrake warning light should come on. Applythe handbrake and switch off the ignition

4

Power steering fluid levelBefore you start:4 Park the car on level ground.4 Set the steering wheel straight-ahead.4 The engine should be turned off.

Safety First! l The need for frequent topping-upindicates a leak, which should be investigatedimmediately.

For the check to beaccurate, the steering mustnot be turned once theengine has been stopped.

The fluid level is visible through thetranslucent material of the reservoir, andshould be between the maximum (A) and

minimum (B) level lines marked on the side ofthe reservoir.

1 If topping-up is necessary, and beforeremoving the cap, wipe the area so thatdirt does not enter the reservoir. Unscrew

the cap, allowing the fluid to drain from thebottom of the cap as it is removed.

2 Top-up to the “MAX” mark, using thespecified type of fluid. Take great carenot to allow dirt to enter the reservoir,

and do not overfill the reservoir. When thelevel is correct, refit the cap.

Tyre condition and pressureIt is very important that tyres are in goodcondition, and at the correct pressure - havinga tyre failure at any speed is highly dangerous.Tyre wear is influenced by driving style - harshbraking and acceleration, or fast cornering,will all produce more rapid tyre wear. As ageneral rule, the front tyres wear out fasterthan the rears. Interchanging the tyres fromfront to rear ("rotating" the tyres) may result inmore even wear. However, if this iscompletely effective, you may have theexpense of replacing all four tyres at once!Remove any nails or stones embedded in thetread before they penetrate the tyre to causedeflation. If removal of a nail does reveal that

the tyre has been punctured, refit the nail sothat its point of penetration is marked. Thenimmediately change the wheel, and have thetyre repaired by a tyre dealer.Regularly check the tyres for damage in theform of cuts or bulges, especially in thesidewalls. Periodically remove the wheels,and clean any dirt or mud from the inside andoutside surfaces. Examine the wheel rims forsigns of rusting, corrosion or other damage.Light alloy wheels are easily damaged by"kerbing" whilst parking; steel wheels mayalso become dented or buckled. A new wheelis very often the only way to overcome severedamage.

New tyres should be balanced when they arefitted, but it may become necessary to re-balance them as they wear, or if the balanceweights fitted to the wheel rim should fall off.Unbalanced tyres will wear more quickly, aswill the steering and suspension components.Wheel imbalance is normally signified byvibration, particularly at a certain speed(typically around 50 mph). If this vibration isfelt only through the steering, then it is likelythat just the front wheels need balancing. If,however, the vibration is felt through thewhole car, the rear wheels could be out ofbalance. Wheel balancing should be carriedout by a tyre dealer or garage.

Tread Depth - visual checkThe original tyres have tread wear safety

bands (B), which will appear when the treaddepth reaches approximately 1.6 mm. Theband positions are indicated by a triangularmark on the tyre sidewall (A).

1 Tread Depth - manual checkAlternatively, tread wear can be

monitored with a simple, inexpensive deviceknown as a tread depth indicator gauge.

2 Tyre Pressure CheckCheck the tyre pressures regularly with

the tyres cold. Do not adjust the tyrepressures immediately after the vehicle hasbeen used, or an inaccurate setting will result.

3

Tyre tread wear patterns

Shoulder Wear

Underinflation (wear on both sides)Under-inflation will cause overheating of thetyre, because the tyre will flex too much, andthe tread will not sit correctly on the roadsurface. This will cause a loss of grip andexcessive wear, not to mention the danger ofsudden tyre failure due to heat build-up.Check and adjust pressuresIncorrect wheel camber (wear on one side)Repair or renew suspension partsHard corneringReduce speed!

OverinflationOver-inflation will cause rapid wear of thecentre part of the tyre tread, coupled withreduced grip, harsher ride, and the danger ofshock damage occurring in the tyre casing.Check and adjust pressures

If you sometimes have to inflate your car’styres to the higher pressures specified formaximum load or sustained high speed, don’tforget to reduce the pressures to normalafterwards.

Uneven Wear

Front tyres may wear unevenly as a result ofwheel misalignment. Most tyre dealers andgarages can check and adjust the wheelalignment (or "tracking") for a modest charge.Incorrect camber or castorRepair or renew suspension partsMalfunctioning suspensionRepair or renew suspension partsUnbalanced wheelBalance tyresIncorrect toe settingAdjust front wheel alignmentNote: The feathered edge of the tread whichtypifies toe wear is best checked by feel.

Wiper blades

Check the condition of the wiper blades;if they are cracked or show any signs ofdeterioration, or if the glass swept area is

smeared, renew them. For maximum clarity ofvision, wiper blades should be renewedannually, as a matter of course. To remove afront wiper blade, first prise off the securingclips, and disconnect the washer tube fromthe arm.

1 Pull the arm fully away from the glassuntil it locks. Swivel the blade through90°, then pull up the blade securing clip,

and slide the blade out of the arm’s hookedend.

2 On Estate models, to remove a tailgatewiper blade, pull the arm fully away fromthe glass until it locks. Swivel the blade

through 90°, then press the locking tab, andslide the blade out of the arm’s hooked end.

Screenwash additives not only keep thewinscreen clean during foul weather, they alsoprevent the washer system freezing in cold

weather - which is when you are likely to needit most. Don’t top up using plain water as thescreenwash will become too diluted, and will

freeze during cold weather. On no accountuse coolant antifreeze in the washer system- this could discolour or damage paintwork.

Screen washer fluid level

On Estate models, the tailgate washerfluid reservoir is located behind a hingedcover on the right-hand side of the

luggage compartment.

2The windscreen/headlight washer fluidreservoir is located in the scuttle at therear right-hand corner of the engine

compartment.

1 When topping-up the reservoir(s) ascreenwash additive should be added inthe quantities recommended on the

bottle.

Bulbs and fuses

4 Check all external lights and the horn.Refer to the appropriate Sections of Chap-ter 12 for details if any of the circuits arefound to be inoperative.

4 Visually check all accessible wiringconnectors, harnesses and retaining clips forsecurity, and for signs of chafing or damage.

If you need to check yourbrake lights and indicatorsunaided, back up to a wall orgarage door and operate the

lights. The reflected light should showif they are working properly.

If a single indicator light, stop-light orheadlight has failed, it is likely that a bulbhas blown and will need to be replaced.

Refer to Chapter 12 for details. If both stop-lights have failed, it is possible that the switchhas failed (see Chapter 9).

If more than one indicator light or tail lighthas failed it is likely that either a fuse hasblown or that there is a fault in the circuit

(see Chapter 12). The fuses are locatedbehind a panel on the bottom of the driver’sside lower facia panel.

2 To replace a blown fuse, simply pull it outand fit a new fuse of the correct rating(see wiring diagrams in Chapter 12). If the

fuse blows again, it is important that you findout why - a complete checking procedure isgiven in Chapter 12.

BatteryCaution: Before carrying out any work on thevehicle battery, read the precautions given in"Safety first" at the start of this manual.4 Make sure that the battery tray is in goodcondition, and that the clamp is tight.Corrosion on the tray, retaining clamp and thebattery itself can be removed with a solutionof water and baking soda. Thoroughly rinse allcleaned areas with water. Any metal partsdamaged by corrosion should be coveredwith a zinc-based primer, then painted.4 Periodically (approximately every threemonths), check the charge condition of thebattery as described in Chapter 5A.4 If the battery is flat, and you need to jumpstart your vehicle, see Roadside Repairs.

The battery is located on the left-handside of the engine compartment. Theexterior of the battery should be

inspected periodically for damage such as acracked case or cover.

1 Check the tightness of the battery cableclamps (A) to ensure good electricalconnections. You should not be able to

move them. Also check each cable (B) forcracks and frayed conductors.

2

Battery corrosion can be kept to aminimum by applying a layer ofpetroleum jelly to the clamps andterminals after they are reconnected.

If corrosion (white fluffy deposits) isevident, remove the cables from thebattery terminals, clean them with a small

wire brush, then refit them. Tools for cleaningthe battery post and terminals are available.

3 Note that the battery negative terminalstud can be removed for cleaning or

renewal. Unscrew the lead clamp, then pull offthe plastic insulator, and lever off the stud andcover.

1•2 Servicing Specifications

The maintenance intervals in this manualare provided with the assumption that you willbe carrying out the work yourself. These arethe minimum maintenance intervalsrecommended by the manufacturer forvehicles driven daily. If you wish to keep yourvehicle in peak condition at all times, you may

wish to perform some of these proceduresmore often. We encourage frequentmaintenance, because it enhances theefficiency, performance and resale value ofyour vehicle.

If the vehicle is driven in dusty areas, usedto tow a trailer, or driven frequently at slow

speeds (idling in traffic) or on short journeys,more frequent maintenance intervals arerecommended.

When the vehicle is new, it should beserviced by a factory-authorised dealerservice department, in order to preserve thefactory warranty.

The maintenance schedule for models from1994 is given below. When compared with theschedule for earlier models, it will be seen thatalthough the same operations are required, thefrequency with which they are performed haschanged considerably. The specified intervalfor most operations has been extended.

The description of the maintenance tasks inthis Chapter follows the schedule prescribed

for earlier models. When the interval for latermodels varies, this is of course indicated.However, the DIY owner may consider that itis well worth while observing the shorterintervals in any case.

We encourage frequent maintenance,because it enhances the efficiency,performance and ultimately, the resale valueof your vehicle.

If the vehicle is driven in dusty areas, isused to tow a trailer, or driven frequently atslow speeds (idling in traffic) or on shortjourneys, more frequent maintenance intervalsare recommended.

When the vehicle is new, it should beserviced by a factory-authorised dealerservice department, in order to preserve thefactory warranty.

General information1 This Chapter is designed to help the homemechanic maintain his/her vehicle for safety,economy, long life and peak performance.2 The Chapter contains a mastermaintenance schedule, followed by Sectionsdealing specifically with each task in theschedule. Visual checks, adjustments,component renewal and other helpful itemsare included. Refer to the accompanyingillustrations of the engine compartment andthe underside of the vehicle for the locationsof the various components.3 Servicing your vehicle in accordance withthe mileage/time maintenance schedule andthe following Sections will provide a plannedmaintenance programme, which should resultin a long and reliable service life. This is acomprehensive plan, so maintaining someitems but not others at the specified serviceintervals, will not produce the same results.4 As you service your vehicle, you willdiscover that many of the procedures can -and should - be grouped together, because ofthe particular procedure being performed, orbecause of the close proximity of twootherwise-unrelated components to oneanother. For example, if the vehicle is raisedfor any reason, the exhaust can be inspectedat the same time as the suspension andsteering components.5 The first step in this maintenance

programme is to prepare yourself before theactual work begins. Read through all theSections relevant to the work to be carriedout, then make a list and gather together allthe parts and tools required. If a problem isencountered, seek advice from a partsspecialist, or a dealer service department.

2 Intensive maintenance

1 If, from the time the vehicle is new, theroutine maintenance schedule is followedclosely, and frequent checks are made of fluidlevels and high-wear items, as suggestedthroughout this manual, the engine will bekept in relatively good running condition, andthe need for additional work will be minimised.2 It is possible that there will be times whenthe engine is running poorly due to the lack ofregular maintenance. This is even more likelyif a used vehicle, which has not receivedregular and frequent maintenance checks, ispurchased. In such cases, additional workmay need to be carried out, outside of theregular maintenance intervals.3 If engine wear is suspected, a compressiontest will provide valuable informationregarding the overall performance of the maininternal components. Such a test can be usedas a basis to decide on the extent of the workto be carried out. If, for example, acompression test indicates serious internalengine wear, conventional maintenance asdescribed in this Chapter will not greatlyimprove the performance of the engine, and

may prove a waste of time and money, unlessextensive overhaul work is carried out first.4 The following series of operations are thosemost often required to improve theperformance of a generally poor-runningengine:

Primary operationsa) Clean, inspect and test the battery (see

“Weekly checks”).b) Check all the engine-related fluids (see

“Weekly checks”).c) Check the condition and tension of the

auxiliary drivebelt (Section 5).d) Renew the spark plugs (Section 11).e) Inspect the distributor cap and HT leads -

as applicable (Section 22).f) Check the condition of the air cleaner

filter element, and renew if necessary(Section 21).

g) Renew the fuel filter (Section 8).h) Check the condition of all hoses, and

check for fluid leaks (Section 6).i) Check the idle speed and mixture settings

- as applicable (Section 10).

5 If the above operations do not prove fullyeffective, carry out the following secondaryoperations:

Secondary operationsa) Check the charging system (Chapter 5A).b) Check the ignition system (Chapter 5B).c) Check the fuel system (Chapter 4).d) Renew the distributor cap and rotor arm -

as applicable (Chapter 5B).e) Renew the ignition HT leads - as

applicable (Section 22).

3 Engine oil and filter renewal 1Note: On models from 1994, the maker’sspecified interval for this procedure is 9000 miles (15 000 km) or 12 months.Note: A suitable square-section wrench maybe required to undo the sump drain plug onsome models. These wrenches cab beobtained from most motor factors or yourPeugeot dealer.1 Frequent oil and filter changes are the mostimportant preventative maintenanceprocedures which can be undertaken by theDIY owner. As engine oil ages, it becomesdiluted and contaminated, which leads topremature engine wear.2 Before starting this procedure, gathertogether all the necessary tools and materials.

Also make sure that you have plenty of cleanrags and newspapers handy, to mop up anyspills. Ideally, the engine oil should be warm,as it will drain better, and more built-upsludge will be removed with it. Take care,however, not to touch the exhaust or anyother hot parts of the engine when workingunder the vehicle. To avoid any possibility ofscalding, and to protect yourself frompossible skin irritants and other harmfulcontaminants in used engine oils, it isadvisable to wear gloves when carrying outthis work. Access to the underside of thevehicle will be greatly improved if it can beraised on a lift, driven onto ramps, or jackedup and supported on axle stands (see“Jacking and Vehicle Support”). Whichevermethod is chosen, make sure that the vehicleremains level, or if it is at an angle, so that thedrain plug is at the lowest point. Wherenecessary remove the splash guard fromunder the engine.

3 Slacken the drain plug about half a turn; onsome models, a square-section wrench maybe needed to slacken the plug (seeillustration). Position the draining containerunder the drain plug, then remove the plugcompletely. If possible, try to keep the plug

pressed into the sump while unscrewing it byhand the last couple of turns (see HaynesHint) .4 Recover the sealing ring from the drainplug.5 Allow some time for the old oil to drain,noting that it may be necessary to repositionthe container as the oil flow slows to a trickle.6 After all the oil has drained, wipe off thedrain plug with a clean rag. Check the sealingwasher for condition, and renew it ifnecessary. Clean the area around the drainplug opening, then refit and tighten the plug.7 If the filter is also to be renewed, move thecontainer into position under the oil filterwhich is located on the front side of thecylinder block, below the inlet manifold.8 Using an oil filter removal tool if necessary,slacken the filter initially, then unscrew it byhand the rest of the way (see illustration).Empty the oil from the old filter into thecontainer, and discard the filter.9 Use a clean rag to remove all oil, dirt andsludge from the filter sealing area on theengine. Check the old filter to make sure thatthe rubber sealing ring hasn’t stuck to theengine. If it has, carefully remove it.10 Apply a light coating of clean engine oil tothe sealing ring on the new filter, then screw itinto position on the engine. Tighten the filterfirmly by hand only - do not use any tools.Wipe clean the filter and sump drain plug.

11 Remove the old oil and all tools fromunder the car, then lower the car to theground (if applicable).12 Remove the dipstick then unscrew the oilfiller cap from the cylinder head cover. Fill theengine, using the correct grade and type of oil(see “Weekly checks”). An oil can spout orfunnel may help to reduce spillage. Pour inhalf the specified quantity of oil first, then waita few minutes for the oil to fall to the sump.Continue adding oil a small quantity at a timeuntil the level is up to the lower mark on thedipstick. Finally, bring the level up to theupper mark on the dipstick. Insert thedipstick, and refit the filler cap.13 Start the engine and run it for a fewminutes; check for leaks around the oil filterseal and the sump drain plug. Note that theremay be a delay of a few seconds before the oilpressure warning light goes out when theengine is first started, as the oil circulatesthrough the engine oil galleries and the new oilfilter, before the pressure builds up.14 Switch off the engine, and wait a fewminutes for the oil to settle in the sump oncemore. With the new oil circulated and the filtercompletely full, recheck the level on thedipstick, and add more oil as necessary.15 Dispose of the used engine oil safely, withreference to “General Repair Procedures” inthe Reference section of this manual.

4 Automatic transmission fluidlevel check 1

Note: On models from 1994, the maker’sspecified interval for this procedure is 9000 miles (15 000 km) or 12 months.1 Take the vehicle on a short journey, towarm the transmission up to normal operatingtemperature, then park the vehicle on levelground. The fluid level is checked using thedipstick located at the front of the enginecompartment, directly in front of theengine/transmission. The dipstick top isbrightly-coloured (usually orange) for easyidentification.2 With the engine idling and the selector leverin the “P” (Park) position, withdraw thedipstick from the tube, and wipe all the fluidfrom its end with a clean rag or paper towel.Insert the clean dipstick back into the tube asfar as it will go, then withdraw it once more.Note the fluid level on the end of the dipstick;it should be between the upper and lowermarks (see illustrations).

3 If topping-up is necessary, add the requiredquantity of the specified fluid to thetransmission via the dipstick tube. Use afunnel with a fine mesh gauze, to avoidspillage, and to ensure that no foreign matterenters the transmission. Note: Never overfillthe transmission so that the fluid level is abovethe upper mark.4 After topping-up, take the vehicle on ashort run to distribute the fresh fluid, thenrecheck the level again, topping-up ifnecessary.5 Always maintain the level between the twodipstick marks. If the level is allowed to fallbelow the lower mark, fluid starvation mayresult, which could lead to severetransmission damage.6 Frequent need for topping-up indicates thatthere is a leak, which should be found andcorrected before it becomes serious.

5 Auxiliary drivebelt check and renewal 3

Note: On models from 1994, the maker’sspecified interval for this procedure is 18 000 miles (30 000 km).Note: Peugeot specify the use of a specialelectronic tool (SEEM C.TRONIC type 105 belttensioning measuring tool) to correctly set theauxiliary drivebelt tension. If access to thisequipment cannot be obtained, anapproximate setting can be achieved usingthe method described below. If the methoddescribed is used, the tension should be

checked using the special electronic tool atthe earliest opportunity.1 Except for XU9J4 16-valve engines, allmodels are fitted with one auxiliary drivebeltdriven from the crankshaft pulley on the right-hand side of the engine. On non-airconditioning models the belt drives thealternator and power steering pump and itstension is adjusted manually. On models fittedwith air conditioning it drives the alternator,power steering pump and the air conditioningcompressor. On XU9J4 models a separatedrivebelt drives the power steering pump froma pulley on the end of the camshaft.

Checking the auxiliary drivebelt condition

Except XU9J4 16-valve power steering drivebelt2 Apply the handbrake, then jack up the frontof the car and support it on axle stands (see“Jacking and Vehicle Support”). Remove theright-hand front roadwheel.3 Remove the engine undercover andwheelarch cover as applicable.4 Using a suitable socket and extension barfitted to the crankshaft sprocket/pulley bolt,rotate the crankshaft so that the entire lengthof the drivebelt can be examined. Examine thedrivebelt for cracks, splitting, fraying ordamage. Check also for signs of glazing (shinypatches) and for separation of the belt plies.Renew the belt if worn or damaged.5 If the condition of the belt is satisfactory, onmodels where the belt is adjusted manually,check the drivebelt tension as describedbelow. On models with an automatic spring-loaded tensioner, there is no need to checkthe drivebelt tension.

XU9J4 16-valve power steering drivebelt6 The power steering drivebelt is positionedon the left-hand end of the cylinder head.Examine the full length of the drivebelt forcracks, splitting, fraying or damage. Ifnecessary turn the engine with a spanner onthe crankshaft pulley or by engaging 4th gearand pushing the car (for safety, the car mustbe on level ground). Check also for signs ofglazing (shiny patches) and for separation ofthe belt plies.7 If the condition of the belt is satisfactory,check the drivebelt tension as described laterin this Section.

Removal12 If not already done, proceed as describedin paragraphs 2 and 3.13 Disconnect the battery negative lead.14 Slacken the tensioner pulley bracketadjustment/mounting bolts (one located in themiddle of the pulley and the other locatedbelow on the bracket (see illustration).15 Fully tighten the adjustment bolt to itsstop, then slip the drivebelt from the pulleys(see illustration).

Refitting16 If the belt is being renewed, ensure thatthe correct type is used. Fit the belt aroundthe pulleys, and take up the slack in the beltby tightening the adjuster bolt. Ensure that theribs on the belt are correctly engaged with thegrooves in the pulleys.17 Tension the drivebelt as described in thefollowing paragraphs.

Tensioning18 If not already done, proceed as describedin paragraphs 2 and 3.19 Correct tensioning of the drivebelt willensure that it has a long life. A belt which istoo slack will slip and perhaps squeal.Beware, however, of overtightening, as thiscan cause wear in the alternator bearings.20 The belt should be tensioned so that,under firm thumb pressure, there is approxi-mately 5.0 mm of free movement at the mid-point between the pulleys on the longest beltrun (see the note at the start of this Section).21 To adjust, unscrew the adjustment boltuntil the tension is correct, then rotate thecrankshaft a couple of times, and recheck thetension. Securely tighten the tensioner pulleybracket adjustment/mounting bolts.22 Reconnect the battery negative lead.23 Refit the engine undercover andwheelarch cover. Refit the roadwheel, andlower the vehicle to the ground.

6 Hose and fluid leak check 1Note: On models from 1994, the maker’sspecified interval for this procedure is9000 miles (15 000 km) or 12 months.1 Visually inspect the engine joint faces,gaskets and seals for any signs of water, oil orfuel leaks. Pay particular attention to the areasaround the camshaft cover, cylinder head, oilfilter and sump joint faces. Bear in mind that,over a period of time, some slight seepagefrom these areas is to be expected. What youare really looking for is any indication of aserious leak. Should a leak be found, renewthe offending gasket or oil seal by referring tothe appropriate Chapters in this manual.2 Also check the security and condition of allthe engine-related pipes and hoses. Ensurethat all cable-ties or securing clips are in placeand in good condition. Clips which are brokenor missing can lead to chafing of the hoses,pipes, or wiring, which could cause moreserious problems in the future.3 Carefully check the radiator hoses andheater hoses along their entire length. Renewany hose which is cracked, swollen, ordeteriorated. Cracks will show up better if thehose is squeezed. Pay close attention to thehose clips that secure the hoses to thecooling system components. Hose clips canpinch and puncture hoses, resulting in coolingsystem leaks. If the original Peugeot crimped-type hose clips are used, it may be a goodidea to replace them with standard worm-drive hose clips.

4 Inspect the cooling system (hoses, jointfaces, etc.) for leaks (see Haynes Hint).5 Where any problems of this nature arefound on system components, renew thecomponent or gasket, referring to Chapter 3.6 Where applicable, inspect the automatictransmission fluid cooler hoses for leaks ordeterioration.7 With the vehicle raised, inspect the petroltank and filler neck for punctures, cracks, andother damage. The connection between thefiller neck and tank is especially critical.Sometimes, a rubber filler neck or connectinghose will leak due to loose retaining clamps ordeteriorated rubber.8 Carefully check all rubber hoses and metalfuel lines leading away from the petrol tank.Check for loose connections, deterioratedhoses, crimped lines, and other damage. Payparticular attention to the vent pipes andhoses, which often loop up around the fillerneck, and can become blocked or crimped.Follow the lines to the front of the vehicle,carefully inspecting them all the way. Renewdamaged sections as necessary.9 From within the engine compartment,check the security of all fuel hose attachmentsand pipe unions, and inspect the fuel hosesand vacuum hoses for kinks, chafing anddeterioration.10 Where applicable, check the condition ofthe power steering fluid hoses and pipes.

type hose clips are fitted, cut them off anddiscard them; use standard worm-drive hoseclips on refitting.3 Note the direction of the arrow marked onthe filter body. Unclip the filter from itsretaining bracket, and remove it from thevehicle.4 Connect the fuel hoses to the new filter.Make sure that the arrow on the filter body ispointing in the direction of the fuel flow, ie.towards the fuel pump. Secure the hoses inposition by securely tightening the retainingclips, then clip the filter back into position inits retaining bracket.5 At the same time, check the fuel reservoirtank on the side of the carburettor for sediment.Remove the reservoir as necessary for cleaning.6 The fuel connections on the reservoir are asfollows.a) Top hose - return to tank.b) Middle hose - supply from pump via filter.c) Lower hose - to carburettor inlet.

Fuel injection models7 The fuel filter is situated underneath the rearof the vehicle, mounted on the right-hand sideof the fuel tank. To gain access to the filter,chock the front wheels, then jack up the rearof the vehicle and support it on axle stands(see “Jacking and Vehicle Support”).8 Clamp the fuel hose on the tank side of thefilter. Bearing in mind the information given inthe relevant Part of Chapter 4 on depres-surising the fuel system, release the clips anddisconnect the fuel hoses from the filter. Beprepared for fuel spillage (see illustration).9 Note the direction of the arrow marked onthe filter body. Slacken the retaining clampscrew, then slide the filter out of the clamp,and remove it from underneath the vehicle.10 Dispose safely of the old filter; it will behighly-inflammable, and may explode ifthrown on a fire.11 Slide the new filter into position in theclamp, ensuring that the arrow on the filterbody is pointing in the direction of the fuelflow, ie. towards the throttle body/fuel rail.This can be determined by tracing the fuelhoses back along their length.12 Connect the fuel hoses to the filter, andsecure them in position with their retainingclips. Remove the hose clamp.

13 Start the engine, and check the filter hoseconnections for leaks. Lower the vehicle tothe ground on completion.

9 Accelerator cable check and adjustment 1

Refer to Chapter 4A or 4B.

10 Idle speed and mixturecheck and adjustment 3

Note: On models from 1994, the maker’sspecified interval for this procedure is 18 000 miles (30 000 km).1 Before checking the idle speed and mixturesetting, always check the following first:a) Check that (where adjustable) the ignition

timing is accurate (Chapter 5B).b) Check that the spark plugs are in good

condition and correctly gapped (Section 11).c) Check that the accelerator cable (and on

carburettor models, the choke cable) iscorrectly adjusted (refer to the relevantPart of Chapter 4).

d) Check that the crankcase breather hosesare secure, with no leaks or kinks(Sections 7 and 29).

e) Check that the air cleaner filter element isclean (Section 21).

f) Check that the exhaust system is in goodcondition (refer to the relevant Part ofChapter 4).

g) If the engine is running roughly, check thecompression pressures and valveclearances as described in Chapter 2.

h) On fuel injection models, check that thefuel injection/ignition system warning lightis not illuminated (refer to the relevantPart of Chapter 4).

2 Take the car on a journey of sufficientlength to warm it up to normal operatingtemperature. Note: Adjustment should ideallybe completed within two minutes of return,without stopping the engine. If the radiatorelectric cooling fan operates, wait for thecooling fan to stop. If adjustment takes longerthan stated, regularly clear any excess fuelfrom the inlet manifold by revving the enginetwo or three times to about 2000 rpm, thenallow it to idle again.

Carburettor models3 Ensure that all electrical loads are switchedoff, and that the choke lever is pushed fully in.If the car does not have a tachometer, connectone following its manufacturer’s instructions.Note the idle speed, and compare it with thatspecified. Note: Models with air conditioninghave an idle compensation device, and the airconditioning compressor must be runningwhile the idle speed is being checked andadjusted.4 Using a suitable flat-bladed screwdriver,screw in the idle adjusting screw (to increasethe speed) or out as necessary to obtain thespecified speed. The screw is located on thecarburettor on non-air conditioning models,and on the idle compensating device on airconditioning models (see illustrations).5 The idle mixture (exhaust gas CO level) isset at the factory, and should require nofurther adjustment. If, due to a change inengine characteristics (carbon build-up, borewear etc) or after a major carburettoroverhaul, the mixture becomes incorrect, itcan be reset. Note, however, that an exhaustgas analyser (CO meter) will be required tocheck the mixture, and to set it with thenecessary standard of accuracy. If this is notavailable, the car must be taken to a Peugeotdealer for the work to be carried out.6 Follow the exhaust gas analysermanufacturer’s instructions to check theexhaust gas CO level.

All other fuel injection systems37 Experienced home mechanics, with aconsiderable amount of skill and equipment(including a tachometer and an accurateexhaust gas analyser) may be able to checkthe exhaust CO level and the idle speed.However, if these are found to be in need ofadjustment, the car must be taken to asuitably-equipped Peugeot dealer.38 On models with a Magneti Marelli enginemanagement (fuel injection/ignition) system,adjustment of the mixture setting (exhaust gasCO level) is possible, but adjustments canonly be made by reprogramming the enginemanagement ECU using special electronictest equipment which is connected to thediagnostic connector (see Chapter 4).39 On all other vehicles, adjustments are notpossible. If the idle speed or the exhaust gasCO level is incorrect, there must be a fault inthe engine management system, and thevehicle should be taken to a Peugeot dealerfor testing (see Chapter 4).

11 Spark plug renewal 2Note: On models from 1994, the maker’sspecified interval for this procedure is 18 000 miles (30 000 km).1 The correct functioning of the spark plugs isvital for the correct running and efficiency of

the engine. It is essential that the plugs fittedare appropriate for the engine (the suitabletype is specified at the beginning of thisChapter). If this type is used, and the engine isin good condition, the spark plugs should notneed attention between scheduledreplacement intervals. Spark plug cleaning israrely necessary, and should not beattempted unless specialised equipment isavailable, as damage can easily be caused tothe firing ends.2 On 16-valve models, to gain access to thespark plugs, the access cover fitted over thecentre of the cylinder head must first beremoved. Undo the eight bolts, noting theposition of the wiring retaining clip, andremove the cover (see illustration).3 On other models, to improve access tosome of the plugs, it may be necessary toremove the air inlet duct (refer to Chapter 4 forfurther information).4 On 1998 cc 16-valve models, pull the HTcoils off the spark plugs. If necessary, toremove the possibility of the HT coils beingconnected to the wrong spark plugs onrefitting, mark the coils 1 to 4 (No 1 cylinder isat the transmission end of the engine).5 On all other models, if the marks on theoriginal-equipment spark plug (HT) leadscannot be seen, mark the leads 1 to 4,corresponding to the cylinder the lead serves(No 1 cylinder is at the transmission end of theengine). Pull the leads from the plugs bygripping the end fitting, not the lead,otherwise the lead connection may befractured (see illustration).

6 It is advisable to remove the dirt from thespark plug recesses, using a clean brush,vacuum cleaner or compressed air beforeremoving the plugs, to prevent dirt droppinginto the cylinders.7 Unscrew the plugs using a spark plugspanner, suitable box spanner, or a deepsocket and extension bar (see illustration).Keep the socket aligned with the spark plug -if it is forcibly moved to one side, the ceramicinsulator may be broken off. As each plug isremoved, examine it as follows.8 Examination of the spark plugs will give agood indication of the condition of the engine.If the insulator nose of the spark plug is cleanand white, with no deposits, this is indicativeof a weak mixture or too hot a plug (a hot plugtransfers heat away from the electrode slowly,a cold plug transfers heat away quickly).9 If the tip and insulator nose are coveredwith hard black-looking deposits, then this isindicative that the mixture is too rich. Shouldthe plug be black and oily, then it is likely thatthe engine is fairly worn, as well as the mixturebeing too rich.

10 If the insulator nose is covered with lighttan to greyish-brown deposits, then themixture is correct, and it is likely that theengine is in good condition.11 The spark plug electrode gap is ofconsiderable importance as, if it is too large ortoo small, the size of the spark and itsefficiency will be seriously impaired. The gapshould be set to the value given in the Specifi-cations at the beginning of this Chapter.12 To set the gap, measure it with a feelerblade, then bend the outer plug electrode untilthe correct gap is achieved (see illustration).The centre electrode should never be bent, asthis may crack the insulator and cause plugfailure, if nothing worse. If using feeler blades,the gap is correct when the appropriate-sizeblade is a firm, sliding fit.13 Special spark plug electrode gapadjusting tools are available from most motoraccessory shops, or from some spark plugmanufacturers.14 Before fitting the spark plugs, check thatthe threaded connector sleeves (on top of theplug) are tight, and that the plug exteriorsurfaces and threads are clean. It is very oftendifficult to insert spark plugs into their holeswithout cross-threading them. To avoid thispossibility, fit a short length of hose over theend of the spark plug (see Haynes Hint).15 Remove the rubber hose (if used), andtighten the plug to the specified torque (see“Specifications”) using the spark plug socketand a torque wrench. Refit the remainingplugs in the same way.16 Connect the HT leads in the correct order,and refit any components removed foraccess. On 1998 cc 16-valve models, connectthe HT coils in their correct order.

12 Clutch adjustment checkand control mechanismlubrication 2

Note: On models from 1994, the maker’sspecified interval for this procedure is 9000 miles (15 000 km) or 12 months for clutchadjustment, and 18 000 miles (30 000 km) forlubrication.1 Check that the clutch pedal movessmoothly and easily through its full travel.

2 The clutch itself should function correctly,with no trace of slip or drag.3 Where possible, adjust the clutch cable ifnecessary, as described in Chapter 6.4 If excessive effort is required to operate theclutch, check first that the cable is correctlyrouted and undamaged. Remove the pedal,and make sure that its pivot is properlygreased. Refer to Chapter 6 for furtherinformation.

13 Driveshaft gaiter check 1Note: On models from 1994, the maker’sspecified interval for this procedure is 9000 miles (15 000 km) or 12 months.

With the vehicle raised and securelysupported on stands, turn the steering ontofull lock, then slowly rotate the roadwheel.Inspect the condition of the outer constantvelocity (CV) joint rubber gaiters, whilesqueezing the gaiters to open out the folds(see illustration). Check for signs of cracking,splits, or deterioration of the rubber, whichmay allow the grease to escape, and lead towater and grit entry into the joint. Also checkthe security and condition of the retainingclips. Repeat these checks on the inner CVjoints. If any damage or deterioration is found,the gaiters should be renewed without delayas described in Chapter 8.

At the same time, check the generalcondition of the CV joints themselves, by firstholding the driveshaft and attempting to rotate

It is often difficult to insert spark plugsinto their holes without cross-threadingthem. To avoid this possibility, fit ashort length of 5/16 inch internaldiameter rubber hose over the end ofthe spark plug. The flexible hose acts asa universal joint to help align the plugwith the plug hole. Should the plugbegin to cross-thread, the hose will slipon the spark plug, preventing threaddamage to the cylinder head.

14 Front and rear disc pad check 1

Note: On models from 1994, the maker’sspecified interval for this procedure is 18 000 miles (30 000 km) for the front brakepads, and 36 000 miles (60 000 km) for therear brake pads or shoes.1 Firmly apply the handbrake, then jack upthe front or rear of the car (as applicable) andsupport it securely on axle stands (see“Jacking and Vehicle Support”). Remove thefront or rear roadwheels.

2 If any pad’s friction material is worn to thespecified thickness or less, all four pads mustbe renewed as a set.3 For a comprehensive check, the brake padsshould be removed and cleaned. Theoperation of the caliper can then also bechecked, and the condition of the brake discitself can be fully examined on both sides.Refer to Chapter 9 for further information.

15 Handbrake check andadjustment 3

Refer to Chapter 9.

16 Steering and suspension check 2

Note: On models from 1994, the maker’sspecified interval for this procedure is 9000 miles (15 000 km) or 12 months.

Front suspension and steering check1 Raise the front of the car, and support on axlestands (see “Jacking and Vehicle Support”).

2 Inspect the balljoint dust covers and thesteering rack-and-pinion gaiters for splits,chafing or deterioration. Any wear of thesecomponents will cause loss of lubricant, withdirt and water entry, resulting in rapiddeterioration of the balljoints or steering gear.3 On vehicles with power steering, check thefluid hoses for chafing or deterioration, andthe pipe and hose unions for fluid leaks. Alsocheck for signs of fluid leakage underpressure from the steering gear rubbergaiters, which would indicate failed fluid sealswithin the steering gear.4 Grasp the roadwheel at the 12 o’clock and 6 o’clock positions, and try to rock it (seeillustration). Very slight free play may be felt,but if the movement is appreciable, furtherinvestigation is necessary to determine thesource. Continue rocking the wheel while anassistant depresses the footbrake. If themovement is now eliminated or significantlyreduced, it is likely that the hub bearings areat fault. If the free play is still evident with thefootbrake depressed, then there is wear in thesuspension joints or mountings.5 Now grasp the wheel at the 9 o’clock and 3 o’clock positions, and try to rock it asbefore. Any movement felt now may again becaused by wear in the hub bearings or thesteering track-rod balljoints. If the outerballjoint is worn, the visual movement will beobvious. If the inner joint is suspect, it can befelt by placing a hand over the rack-and-pinionrubber gaiter and gripping the track-rod. If thewheel is now rocked, movement will be felt atthe inner joint if wear has taken place.6 Using a large screwdriver or flat bar, checkfor wear in the suspension mounting bushesby levering between the relevant suspensioncomponent and its attachment point. Somemovement is to be expected, as themountings are made of rubber, but excessivewear should be obvious. Also check thecondition of any visible rubber bushes,looking for splits, cracks or contamination ofthe rubber.7 With the car standing on its wheels, have anassistant turn the steering wheel back andforth, about an eighth of a turn each way.There should be very little, if any, lostmovement between the steering wheel androadwheels. If this is not the case, closelyobserve the joints and mountings previouslydescribed. In addition, check the steeringcolumn universal joints for wear, and alsocheck the rack-and-pinion steering gear itself.

Rear suspension check8 Chock the front wheels, then jack up therear of the car and support on axle stands(see “Jacking and Vehicle Support”).

9 Working as described previously for thefront suspension, check the rear hubbearings, the suspension bushes and theshock absorber mountings for wear.

Suspension strut/shock absorber check10 Check for any signs of fluid leakagearound the suspension strut/shock absorberbody, or from the rubber gaiter around thepiston rod. Should any fluid be noticed, thesuspension strut/shock absorber is defectiveinternally, and should be renewed. Note:Suspension struts/shock absorbers shouldalways be renewed in pairs on the same axle.11 The efficiency of the suspensionstrut/shock absorber may be checked bybouncing the vehicle at each corner.Generally speaking, the body will return to itsnormal position and stop after beingdepressed. If it rises and returns on arebound, the suspension strut/shockabsorber is probably suspect. Examine alsothe suspension strut/shock absorber upperand lower mountings for any signs of wear.

20 Coolant renewal 2Note: On models from 1994, the maker’sspecified interval for this procedure is every 2 years, regardless of mileage.

Cooling system draining

1 With the engine completely cold, removethe expansion tank filler cap. Turn the capanti-clockwise until it reaches the first stop.Wait until any pressure remaining in the

system is released, then push the cap down,turn it anti-clockwise to the second stop, andlift it off.2 Position a suitable container beneath thecoolant drain outlet at the lower left-hand sideof the radiator.3 Loosen the drain plug (there is no need toremove it completely) and allow the coolant todrain into the container. If desired, a length oftubing can be fitted to the drain outlet todirect the flow of coolant during draining (seeillustration).

4 To assist draining, open the cooling systembleed screws. On all except 1.4 litre engines,the bleed screws are located in the thermostatcover and thermostat housing. On 1.4 litreengines, the bleed screws are located in thethermostat housing, and in the cylinder headcoolant bypass hose. Additionally, on 2.0 litreXU10J4 engines, there is a bleed screwlocated in the coolant bypass hose behind thecylinder head. All models also have a bleedscrew located at the top left-hand corner ofthe radiator (see illustrations).

18 Hinge and lock lubrication 1Note: On models from 1994, the maker’sspecified interval for this procedure is 36 000 miles (60 000 km).1 Work around the vehicle, and lubricate thehinges of the bonnet, doors and tailgate with alight machine oil.2 Lightly lubricate the bonnet releasemechanism and exposed section of innercable with a smear of grease.3 Check carefully the security and operationof all hinges, latches and locks, adjustingthem where required. Check the operation ofthe central locking system (if fitted).4 Check the condition and operation of thetailgate struts, renewing them if either isleaking or is no longer able to support thetailgate securely when raised.

19 Air conditioning refrigerantcheck 1

Note: On models from 1994, the maker’sspecified interval for this procedure is 18 000 miles (30 000 km).

1 In order to check the condition of therefrigerant, a humidity indicator and a sightglass are provided on top of the drier bottle,located in the front, left-hand corner of theengine compartment (see illustration).

Refrigerant humidity check2 Check the colour of the humidity indicator.Blue indicates that the condition of therefrigerant is satisfactory. Pink indicates that

the refrigerant is saturated with humidity. Ifthe indicator shows red, the system should bedrained and recharged, and a new drier bottleshould be fitted. Note: The system should bedrained and recharged only by a Peugeotdealer or air conditioning specialist. Do notattempt to carry out the work yourself, as therefrigerant is a highly-dangerous substance(refer to Chapter 3).

Refrigerant flow check3 Run the engine, and switch on the airconditioning.4 After a few minutes, inspect the sight glass,and check the fluid flow. Clear fluid should bevisible - if not, the following will help todiagnose the problem:

a) Clear fluid flow - the system is functioningcorrectly.

b) No fluid flow - have the system checkedfor leaks by a Peugeot dealer or airconditioning specialist.

c) Continuous stream of clear air bubbles influid - refrigerant level low - have thesystem recharged by a Peugeot dealer orair conditioning specialist.

d) Milky air bubbles visible - high humidity(see paragraph 2).

Warning: Wait until the engine iscold before starting thisprocedure. Do not allowantifreeze to come in contact

with your skin, or with the paintedsurfaces of the vehicle. Rinse off spillsimmediately with plenty of water. Neverleave antifreeze lying around in an opencontainer, or in a puddle in the drivewayor on the garage floor. Children and petsare attracted by its sweet smell, butantifreeze can be fatal if ingested.

5 On 1.4 litre and 2.0 litre engines, when theflow of coolant stops, reposition the containerbelow the cylinder block drain plug. On 1.4 litre engines, the drain plug is located atthe front left-hand end of the cylinder block. On 2.0 litre engines, the drain plug islocated at the rear left-hand end of thecylinder block, next to the rear enginemounting (see illustrations). On 1.6, 1.8 and1.9 litre engines, no cylinder block drain plugis fitted.6 Where applicable, remove the cylinderblock drain plug, and allow the coolant todrain into the container.7 If the coolant has been drained for a reasonother than renewal, then provided it is cleanand less than two years old, it can be re-used,though this is not recommended.8 Refit and tighten the radiator and cylinderblock drain plugs, as applicable, oncompletion of draining.

Cooling system flushing9 If coolant renewal has been neglected, or ifthe antifreeze mixture has become diluted,then in time, the cooling system may graduallylose efficiency, as the coolant passagesbecome restricted due to rust, scale deposits,and other sediment. The cooling systemefficiency can be restored by flushing thesystem clean.10 The radiator should be flushedindependently of the engine, to avoidunnecessary contamination.

Radiator flushing11 To flush the radiator, first tighten the

radiator drain plug, and the radiator bleedscrew, where applicable.12 Disconnect the top and bottom hoses andany other relevant hoses from the radiator,with reference to Chapter 3.13 Insert a garden hose into the radiator topinlet. Direct a flow of clean water through theradiator, and continue flushing until cleanwater emerges from the radiator bottomoutlet.14 If after a reasonable period, the water stilldoes not run clear, the radiator can be flushedwith a good proprietary cleaning agent. It isimportant that the manufacturer’s instructionsare followed carefully. If the contamination isparticularly bad, insert the hose in the radiatorbottom outlet, and reverse-flush the radiator.

Engine flushing15 To flush the engine, first refit and tightenthe cylinder block drain plug (whereapplicable), and tighten the cooling systembleed screws.16 Remove the thermostat as described inChapter 3, then temporarily refit thethermostat cover.17 With the top and bottom hosesdisconnected from the radiator (see Chapter 3- it may be preferable to disconnect thebottom hose from the engine), insert a gardenhose into the radiator top hose. Direct a cleanflow of water through the engine, andcontinue flushing until clean water emergesfrom the radiator bottom hose.18 On completion of flushing, refit thethermostat and reconnect the hoses withreference to Chapter 3.

Cooling system filling19 Before attempting to fill the coolingsystem, make sure that all hoses and clips arein good condition, and that the clips are tight.Note that an antifreeze mixture must be usedall year round, to prevent corrosion of theengine components (see following sub-Section). Also check that the radiator andcylinder block drain plugs, as applicable, arein place and tight.20 Remove the expansion tank cap.21 Open all the cooling system bleed screws(see paragraph 4).22 Some of the cooling system hoses arepositioned at a higher level than the top of theradiator expansion tank. It is thereforenecessary to use a “header tank” whenrefilling the cooling system, to reduce thepossibility of air being trapped in the system.Although Peugeot dealers use a specialheader tank, the same effect can be achievedby using a suitable bottle, with a seal betweenthe bottle and the expansion tank (seeillustration and Haynes Hint).23 Fit the “header tank” to the expansiontank and slowly fill the system. Coolant willemerge from each of the bleed screws in turn,starting with the lowest screw. As soon ascoolant free from air bubbles emerges fromthe lowest screw, tighten that screw, andwatch the next bleed screw in the system.Repeat the procedure until the coolant is

Keep the “header tank”full during this procedure.24 Once all the bleed screws are securelytightened, remove the “header tank” and refitthe expansion tank cap.25 Start the engine, and run it at 1500 rpm.Maintain this engine speed until the radiatorcooling fan has cut in and out three times.26 Allow the engine to run at idle speed for afew minutes.27 Stop the engine, and wait for at least tenminutes.28 Place a large wad of rag around theexpansion tank cap, and around your hand,then carefully remove the expansion tank cap.Turn the cap anti-clockwise until it reachesthe first stop. Wait until any pressureremaining in the system is released, then pushthe cap down, turn it anti-clockwise to thesecond stop, and lift it off.

29 Check the coolant level, and if necessarytop-up the expansion tank to just above the“MAXI” level mark (see “Weekly checks”).30 Refit the expansion tank cap.

Antifreeze mixture31 The antifreeze should always be renewedat the specified intervals. This is necessarynot only to maintain the antifreeze properties,but also to prevent corrosion which wouldotherwise occur as the corrosion inhibitorsbecome progressively less effective.32 Always use an ethylene-glycol basedantifreeze which is suitable for use in mixed-metal cooling systems. The quantity ofantifreeze and levels of protection areindicated in the Specifications.33 Before adding antifreeze, the coolingsystem should be completely drained,preferably flushed, and all hoses checked forcondition and security.34 After filling with antifreeze, a label shouldbe attached to the expansion tank, stating thetype and concentration of antifreeze used,and the date installed. Any subsequenttopping-up should be made with the sametype and concentration of antifreeze.35 Do not use engine antifreeze in thewindscreen/tailgate washer system, as it willcause damage to the vehicle paintwork. Ascreenwash additive should be added to thewasher system in the quantities stated on thebottle.

1 The ignition system components should bechecked for damage or deterioration asdescribed under the relevant sub-heading.

Ignition systems incorporating a distributorGeneral component check2 The spark plug (HT) leads should bechecked whenever new spark plugs areinstalled in the engine.3 Ensure that the leads are numbered beforeremoving them, to avoid confusion whenrefitting. Pull the leads from the plugs bygripping the end fitting, not the lead,otherwise the lead connection may befractured.4 Check inside the end fitting for signs ofcorrosion, which will look like a white crustypowder. Push the end fitting back onto thespark plug, ensuring that it is a tight fit on theplug. If not, remove the lead again, and usepliers to carefully crimp the metal connectorinside the end fitting until it fits securely on theend of the spark plug.5 Using a clean rag, wipe the entire length ofthe lead to remove any built-up dirt and

grease. Once the lead is clean, check forburns, cracks and other damage. Do not bendthe lead excessively, or pull the leadlengthways - the conductor inside mightbreak.6 Disconnect the other end of the lead fromthe distributor cap. Again, pull only on the endfitting. Check for corrosion and a tight fit in thesame manner as the spark plug end. If anohmmeter is available, check the resistance ofthe lead by connecting the meter between thespark plug end of the lead and the segmentinside the distributor cap. Refit the leadsecurely on completion.7 Check the remaining leads one at a time, inthe same way.8 If new spark plug (HT) leads are required,purchase a set for your specific car andengine.9 Remove the distributor cap by unscrewingits retaining screws. Wipe it clean, andcarefully inspect it inside and out for signs ofcracks, carbon tracks (tracking) and worn,burned or loose contacts; check that thecap’s carbon brush is unworn, free to moveagainst spring pressure, and making goodcontact with the rotor arm. Also inspect thecap seal for signs of wear or damage, andrenew if necessary. Remove the rotor armfrom the distributor shaft and inspect it (seeillustration). It is common practice to renewthe cap and rotor arm whenever new sparkplug (HT) leads are fitted. When fitting a newcap, remove the leads from the old cap one ata time, and fit them to the new cap in theexact same location - do not simultaneouslyremove all the leads from the old cap, or firingorder confusion may occur.

23 Automatic transmission fluidrenewal 2

Note: On models from 1994, the maker’sspecified interval for this procedure is 18 000 miles (30 000 km).1 Take the vehicle on a short run, to warm thetransmission up to normal operatingtemperature.2 Park the car on level ground, then switch offthe ignition and apply the handbrake firmly.For improved access, jack up the front of thecar and support it securely on axle stands(see “Jacking and Vehicle Support”). Note

that, when refilling and checking the fluidlevel, the car must be lowered to the ground,and level, to ensure accuracy.3 Remove the dipstick, then position asuitable container under the transmission. Thetransmission has two drain plugs: one on thesump, and another on the bottom of thedifferential housing (see illustration).4 Unscrew both drain plugs, and allow thefluid to drain completely into the container.

5 When the fluid has finished draining, cleanthe drain plug threads and those of thetransmission casing. Fit a new sealing washerto each drain plug, and refit the plugs to thetransmission, tightening each securely. If thecar was raised for the draining operation, nowlower it to the ground. Make sure that the caris level (front-to-rear and side-to-side).6 Refilling the transmission is an awkwardoperation, adding the specified type of fluid tothe transmission a little at a time via thedipstick tube. Use a funnel with a fine meshgauze, to avoid spillage, and to ensure that noforeign matter enters the transmission. Allowplenty of time for the fluid level to settleproperly.7 Once the level is up to the MAX mark on thedipstick, refit the dipstick. Start the engine,and allow it to idle for a few minutes. Switchthe engine off, then recheck the level,topping-up if necessary. Take the car on ashort run to fully distribute the new fluidaround the transmission, then recheck thefluid level as described in “Weekly checks”.

24 Brake fluid renewal 2Note: On models from 1994, the maker’sspecified interval for this procedure is every 2 years, regardless of mileage.

1 The procedure is similar to that for thebleeding of the hydraulic system as describedin Chapter 9, except that the brake fluidreservoir should be emptied by siphoning,using a clean poultry baster or similar beforestarting, and allowance should be made forthe old fluid to be expelled when bleeding asection of the circuit.2 Working as described in Chapter 9, openthe first bleed screw in the sequence, andpump the brake pedal gently until nearly allthe old fluid has been emptied from themaster cylinder reservoir. Top-up to the“MAX” level with new fluid, and continuepumping until only the new fluid remains in thereservoir, and new fluid can be seen emergingfrom the bleed screw. Tighten the screw, andtop the reservoir level up to the “MAX” levelline.

3 Work through all the remaining bleedscrews in the sequence until new fluid can beseen at all of them. Be careful to keep themaster cylinder reservoir topped-up to abovethe “MIN” level at all times, or air may enterthe system and greatly increase the length ofthe task.4 When the operation is complete, check thatall bleed screws are securely tightened, andthat their dust caps are refitted. Wash off alltraces of spilt fluid, and recheck the mastercylinder reservoir fluid level.5 Check the operation of the brakes beforetaking the car on the road.

Warning: If the fluid is hot, takeprecautions against scalding.Clean the drain plugs, beingespecially careful to wipe any

metallic particles off the magnetic insert.Discard the original sealing washers;these should be renewed whenever theyare disturbed.

Warning: Brake hydraulic fluidcan harm your eyes anddamage painted surfaces, souse extreme caution when

handling and pouring it. Do not use fluidthat has been standing open for sometime, as it absorbs moisture from the air.Excess moisture content can cause adangerous loss of braking effectiveness.

Old hydraulic fluid isinvariably much darker incolour than the new, makingit easy to distinguish the two.

25 Timing belt renewal 4Note: On models from 1994, the maker’sspecified interval for this procedure is 72 000 miles (120 000 km).

Refer to the relevant Part of Chapter 2.

26 Manual transmission oil level check 2

Note: On models from 1994, the maker’sspecified interval for this procedure is 36 000 miles (60 000 km).Note: A suitable square-section wrench maybe required to undo the transmissionfiller/level plug on some models. Thesewrenches can be obtained from most motorfactors or your Peugeot dealer.Haynes Hint: It may be possible to use thesquare end fitting on a ratchet handle (asfound in a typical socket set) to undo theplug.1 Park the car on a level surface. The oil levelmust be checked before the car is driven, orat least 5 minutes after the engine has beenswitched off. If the oil level is checkedimmediately after driving the car, some of theoil will remain distributed around thetransmission components, resulting in aninaccurate level reading.2 Turn the steering wheel on full left-handlock, then where applicable remove the coverfor access to the left-hand side of thetransmission.3 Wipe clean the area around the filler/levelplug, which is on the left-hand end of thetransmission. Unscrew the plug and clean it;discard the sealing washer (see illustration).4 The oil level should reach the lower edge ofthe filler/level hole. A certain amount of oil willhave gathered behind the filler/level plug, andwill trickle out when it is removed; this doesnot necessarily indicate that the level is

correct. To ensure that a true level isestablished, wait until the initial trickle hasstopped, then add oil as necessary until atrickle of new oil can be seen emerging (seeillustration). The level will be correct whenthe flow ceases; use only good-quality oil ofthe specified type.5 Filling the transmission with oil is anextremely awkward operation; above all, allowplenty of time for the oil level to settle properlybefore checking it. If a large amount had to beadded to the transmission, and a largeamount flows out on checking the level, refitthe filler/level plug and take the vehicle on ashort journey so that the new oil is distributedfully around the transmission components,then recheck the level when it has settledagain.6 If the transmission has been overfilled sothat oil flows out as soon as the filler/levelplug is removed, first check that the car iscompletely level (front-to-rear and side-to-side), and allow any surplus oil to drain off intoa suitable container.7 When the level is correct, fit a new sealingwasher to the filler/level plug. Refit the plug,tightening it to the specified torque wrenchsetting. Wash off any spilt oil then whereapplicable refit the access cover.

27 Rear brake shoe check -models with rear drum brakes 2

Note: On models from 1994, the maker’sspecified interval for this procedure is 36 000 miles (60 000 km).

Remove the rear brake drums, and checkthe brake shoes for signs of wear orcontamination. At the same time, also inspectthe wheel cylinders for signs of leakage, andthe brake drum for signs of wear. Refer to therelevant Sections of Chapter 9 for furtherinformation.

28 Pollen filter renewal 1Note: On models from 1994, the maker’sspecified interval for this procedure is 9000 miles (15 000 km) or 12 months.1 On later models, a pollen filter is fitted.2 Open the bonnet.3 Release the securing clips, and withdrawthe plastic cover from the heater air inlet in thepassenger’s side of the scuttle at the rear ofthe engine compartment.4 Unclip the pollen filter from the heater airinlet duct (see illustration).5 Refitting is a reversal of removal.

29 Emissions control systems check 2

Note: On models from 1994, the maker’sspecified interval for this procedure is 18 000 miles (30 000 km).1 Details of the emission control systemcomponents are given in Chapter 4D.2 Checking consists simply of a visual checkfor obvious signs of damaged or leakinghoses and joints.3 Detailed checking and testing of theevaporative and/or exhaust emission systems(as applicable) should be entrusted to aPeugeot dealer.

2 Make sure that all instruments read correctly,and switch on all electrical equipment in turn, tocheck that it functions properly.

Steering and suspension3 Check for any abnormalities in the steering,suspension, handling or road “feel”.4 Drive the vehicle, and check that there areno unusual vibrations or noises.5 Check that the steering feels positive, withno excessive “sloppiness”, or roughness, andcheck for any suspension noises whencornering and driving over bumps.

Drivetrain6 Check the performance of the engine, clutch(where applicable), transmission and driveshafts.7 Listen for any unusual noises from theengine, clutch and transmission.8 Make sure that the engine runs smoothlywhen idling, and that there is no hesitationwhen accelerating.9 Check that, where applicable, the clutchaction is smooth and progressive, that the

drive is taken up smoothly, and that the pedaltravel is not excessive. Also listen for anynoises when the clutch pedal is depressed.10 On manual transmission models, checkthat all gears can be engaged smoothlywithout noise, and that the gear lever action isnot abnormally vague or “notchy”.11 On automatic transmission models, makesure that all gearchanges occur smoothly,without snatching, and without an increase inengine speed between changes. Check thatall the gear positions can be selected with thevehicle at rest. If any problems are found, theyshould be referred to a Peugeot dealer.12 Listen for a metallic clicking sound fromthe front of the vehicle, as the vehicle is drivenslowly in a circle with the steering on full-lock.Carry out this check in both directions. If aclicking noise is heard, this indicates wear in adriveshaft joint, in which case the completedriveshaft must be renewed (see Chapter 8).

Braking system13 Make sure that the vehicle does not pull to

one side when braking, and that the wheelsdo not lock prematurely when braking hard.14 Check that there is no vibration throughthe steering when braking.15 Check that the handbrake operatescorrectly, without excessive movement of thelever, and that it holds the vehicle stationaryon a slope.16 Test the operation of the brake servo unitas follows. Depress the footbrake four or fivetimes to exhaust the vacuum, then start theengine. As the engine starts, there should be anoticeable “give” in the brake pedal asvacuum builds up. Allow the engine to run forat least two minutes, and then switch it off. Ifthe brake pedal is now depressed again, itshould be possible to detect a hiss from theservo as the pedal is depressed. After aboutfour or five applications, no further hissingshould be heard, and the pedal should feelconsiderably harder.

2A•2 TU engine in-car repair procedures

1 General information

How to use this Chapter1 This Part of Chapter 2 describes thoserepair procedures that can reasonably becarried out on the TU series engine while itremains in the car. If the engine has beenremoved from the car and is being dismantledas described in Part C, any preliminarydismantling procedures can be ignored. Referto Part B for the XU series petrol engine.2 Note that, while it may be possiblephysically to overhaul items such as thepiston/connecting rod assemblies while theengine is in the car, such tasks are notnormally carried out as separate operations.Usually, several additional procedures (not tomention the cleaning of components andoilways) have to be carried out. For thisreason, all such tasks are classed as majoroverhaul procedures, and are described inPart C of this Chapter.3 Part C describes the removal of theengine/transmission from the vehicle, and thefull overhaul procedures that can then becarried out.

TU series engine description4 The TU series engine is a well-provenengine which has been fitted to manyprevious Peugeot and Citroën vehicles. Theengine is of the in-line four-cylinder, overheadcamshaft (OHC) type, mounted transversely atthe front of the car. The clutch andtransmission are attached to its left-hand end.The 405 range is fitted with the 1360 ccversion of the engine; carburettor and fuel-injected versions are available (carburettorversions not available in the UK).5 The crankshaft runs in five main bearings.Thrustwashers are fitted to No 2 main bearing(upper half) to control crankshaft endfloat.6 The connecting rods rotate on horizontally-split bearing shells at their big-ends. Thepistons are attached to the connecting rodsby gudgeon pins, which are an interference fitin the connecting rod small-end eyes. Thealuminium-alloy pistons are fitted with threepiston rings - two compression rings and anoil control ring.7 Where the cylinder block is made ofaluminium, replaceable wet liners are fitted.Sealing O-rings are fitted at the base of eachliner, to prevent the escape of coolant into thesump.8 Where the cylinder block is made from cast

iron, the cylinder bores are an integral part ofthe cylinder block. On this type of engine thecylinder bores are sometimes referred to ashaving dry liners.9 The inlet and exhaust valves are eachclosed by coil springs, and operate in guidespressed into the cylinder head; the valve seatinserts are also pressed into the cylinderhead, and can be renewed separately if worn.10 The camshaft is driven by a toothedtiming belt, and operates the eight valves viarocker arms. Valve clearances are adjusted bya screw-and-locknut arrangement. Thecamshaft rotates directly in the cylinder head.The timing belt also drives the coolant pump.11 Lubrication is by means of an oil pump,which is driven (via a chain and sprocket) offthe right-hand end of the crankshaft. It drawsoil through a strainer located in the sump, andthen forces it through an externally-mountedfilter into galleries in the cylinderblock/crankcase. From there, the oil isdistributed to the crankshaft (main bearings)and camshaft. The big-end bearings aresupplied with oil via internal drillings in thecrankshaft, while the camshaft bearings alsoreceive a pressurised supply. The camshaftlobes and valves are lubricated by splash, asare all other engine components.

12 Throughout this manual, it is oftennecessary to identify the engines not only bytheir capacity, but also by their engine codewhich can be found on the left-hand end ofthe front face of the cylinder block. On modelswith an aluminium cylinder block the code isstamped on a plate which is riveted to theblock, and on models with a cast iron cylinderblock the number is stamped on a machinedsurface on the cylinder block, at the flywheelend. The first part of the engine number givesthe engine code - eg “KDX” (see illustration).

Repair operations possible withthe engine in the car13 The following work can be carried out withthe engine in the car:a) Compression pressure - testing.b) Cylinder head cover - removal and refitting.c) Timing belt covers - removal and refitting.d) Timing belt - removal, refitting and

adjustment.e) Timing belt tensioner and sprockets -

removal and refitting.f) Camshaft oil seal(s) - renewal.g) Camshaft and rocker arms - removal,

inspection and refitting.*h) Cylinder head - removal and refitting.i) Cylinder head and pistons - decarbonising.j) Sump - removal and refitting.k) Oil pump - removal, overhaul and refitting.l) Crankshaft oil seals - renewal.m)Engine/transmission mountings -

inspection and renewal.n) Flywheel - removal, inspection and refitting.

*The cylinder head must be removed for thesuccessful completion of this work. Refer toSection 10 for details.

2 Compression test

1 When engine performance is down, or ifmisfiring occurs which cannot be attributed tothe ignition or fuel systems, a compressiontest can provide diagnostic clues as to theengine’s condition. If the test is performedregularly, it can give warning of trouble beforeany other symptoms become apparent.2 The engine must be fully warmed-up to

normal operating temperature, the batterymust be fully charged, and all the spark plugsmust be removed (Chapter 1). The aid of anassistant will also be required.3 On carburettor models, disable the ignitionsystem by disconnecting the ignition HT coillead from the distributor cap and earthing iton the cylinder block. Use a jumper lead orsimilar wire to make a good connection.4 On fuel-injected models, disable theignition system by disconnecting the LT wiringconnector from the ignition HT coil(s),referring to Chapter 5 for further information.5 Fit a compression tester to the No 1cylinder spark plug hole - the type of testerwhich screws into the plug thread is to bepreferred.6 Have the assistant hold the throttle wideopen, and crank the engine on the startermotor. After one or two revolutions, thecompression pressure should build up to amaximum figure, and then stabilise. Recordthe highest reading obtained.7 Repeat the test on the remaining cylinders,recording the pressure in each.8 All cylinders should produce very similarpressures; a difference of more than 2 barsbetween any two cylinders indicates a fault.Note that the compression should build upquickly in a healthy engine; low compressionon the first stroke, followed by gradually-increasing pressure on successive strokes,indicates worn piston rings. A lowcompression reading on the first stroke, whichdoes not build up during successive strokes,indicates leaking valves or a blown headgasket (a cracked head could also be thecause). Deposits on the undersides of thevalve heads can also cause low compression.9 Although Peugeot do not specify exactcompression pressures, as a guide, anycylinder pressure of below 10 bars can beconsidered as less than healthy. Refer to aPeugeot dealer or other specialist if in doubtas to whether a particular pressure reading isacceptable.10 If the pressure in any cylinder is low, carryout the following test to isolate the cause.Introduce a teaspoonful of clean oil into thatcylinder through its spark plug hole, andrepeat the test.11 If the addition of oil temporarily improvesthe compression pressure, this indicates thatbore or piston wear is responsible for thepressure loss. No improvement suggests thatleaking or burnt valves, or a blown headgasket, may be to blame.12 A low reading from two adjacent cylindersis almost certainly due to the head gaskethaving blown between them; the presence ofcoolant in the engine oil will confirm this.13 If one cylinder is about 20 percent lowerthan the others and the engine has a slightlyrough idle, a worn camshaft lobe could be thecause.14 If the compression reading is unusuallyhigh, the combustion chambers are probablycoated with carbon deposits. If this is the

case, the cylinder head should be removedand decarbonised.15 On completion of the test, refit the sparkplugs and reconnect the ignition system.

3 Engine assembly/valvetiming holes - generalinformation and usage

3Note: Do not attempt to rotate the enginewhilst the crankshaft/camshaft are locked inposition. If the engine is to be left in this statefor a long period of time, it is a good idea toplace warning notices inside the vehicle, andin the engine compartment. This will reducethe possibility of the engine being accidentallycranked on the starter motor, which is likely tocause damage with the locking pins in place.1 On all models, timing holes are drilled in thecamshaft sprocket and in the rear of theflywheel. The holes are used to ensure thatthe crankshaft and camshaft are correctlypositioned when assembling the engine (toprevent the possibility of the valves contactingthe pistons when refitting the cylinder head),or refitting the timing belt. When the timingholes are aligned with the special holes in thecylinder head and the front of the cylinderblock, suitable diameter pins can be insertedto lock both the camshaft and crankshaft inposition, preventing them from rotating.Proceed as follows.2 Remove the timing belt upper cover asdescribed in Section 5.3 The crankshaft must now be turned untilthe timing hole in the camshaft sprocket isaligned with the corresponding hole in thecylinder head. The holes are aligned when thecamshaft sprocket hole is in the 2 o’clockposition, when viewed from the right-handend of the engine. The crankshaft can beturned by using a spanner on the crankshaftsprocket bolt, noting that it should always berotated in a clockwise direction (viewed fromthe right-hand end of the engine).4 With the camshaft sprocket hole correctlypositioned, insert a 6 mm diameter bolt or drillthrough the hole in the front, left-hand flangeof the cylinder block, and locate it in thetiming hole in the rear of the flywheel (seeillustration). Note that it may be necessary to

Removal1 Disconnect the battery negative lead.2 Where necessary, undo the bolts securing

the HT lead retaining clips to the rear of thecylinder head cover, and position the clipsclear of the cover.3 Slacken the retaining clip, and disconnectthe breather hose from the left-hand end ofthe cylinder head cover (see illustration).Where the original crimped-type Peugeothose clip is still fitted, cut it off and discard it.Use a standard worm-drive clip on refitting.4 Undo the two retaining nuts, and removethe washer from each of the cylinder headcover studs (see illustration).5 Lift off the cylinder head cover, and removeit along with its rubber seal (see illustration).Examine the seal for signs of damage anddeterioration, and if necessary, renew it.6 Lift off the spacer from each stud, andremove the oil baffle plate (see illustrations).

Refitting7 Carefully clean the cylinder head and covermating surfaces, and remove all traces of oil.8 Fit the rubber seal over the edge of thecylinder head cover, ensuring that it iscorrectly located along its entire length (seeillustration).9 Refit the oil baffle plate to the engine, andlocate the spacers in their recesses in thebaffle plate.10 Carefully refit the cylinder head cover tothe engine, taking great care not to displacethe rubber seal.11 Check that the seal is correctly located,then refit the washers and cover retainingnuts, and tighten them to the specified torque.12 Where necessary, refit the HT lead clips to

the rear of the head cover, and securelytighten their retaining bolts.13 Reconnect the breather hose to thecylinder head cover, securely tightening itsretaining clip, and reconnect the batterynegative lead.

6 Timing belt - general information, removal and refitting 4

Note: Peugeot specify the use of a specialelectronic tool (SEEM C.TRONIC type 105 or105.5 belt tensioning measuring tool) tocorrectly set the timing belt tension. If accessto this equipment cannot be obtained, anapproximate setting can be achieved usingthe method described below. If the methoddescribed is used, the tension must bechecked using the special electronic tool atthe earliest possible opportunity. Do not drivethe vehicle over large distances, or use highengine speeds, until the belt tension is knownto be correct. Refer to a Peugeot dealer foradvice.

General information1 The timing belt drives the camshaft andcoolant pump from a toothed sprocket on thefront of the crankshaft. If the belt breaks orslips in service, the pistons are likely to hit the

valve heads, resulting in extensive (andexpensive) damage.2 The timing belt should be renewed at thespecified intervals (see Chapter 1), or earlier ifit is contaminated with oil, or if it is at all noisyin operation (a “scraping” noise due to unevenwear).3 If the timing belt is being removed, it is awise precaution to check the condition of thecoolant pump at the same time (check forsigns of coolant leakage). This may avoid theneed to remove the timing belt again at a laterstage, should the coolant pump fail.

Removal4 Disconnect the battery negative terminal.5 Align the engine assembly/valve timingholes as described in Section 3, and lock boththe camshaft sprocket and the flywheel inposition. Do not attempt to rotate the enginewhilst the locking tools are in position.6 Remove the timing belt centre and lowercovers as described in Section 5.7 Loosen the timing belt tensioner pulleyretaining nut. Pivot the pulley in a clockwisedirection, using a square-section key fitted tothe hole in the pulley hub, then retighten theretaining nut.8 If the timing belt is to be re-used, use whitepaint or similar to mark the direction ofrotation on the belt (if markings do not alreadyexist) (see illustration). Slip the belt off thesprockets.9 Check the timing belt carefully for any signsof uneven wear, splitting, or oil contamination.Pay particular attention to the roots of theteeth. Renew the belt if there is the slightest

doubt about its condition. If the engine isundergoing an overhaul, and has coveredmore than 36 000 miles (60 000 km) with theexisting belt fitted, renew the belt as a matterof course, regardless of its apparentcondition. The cost of a new belt is nothingwhen compared to the cost of repairs, shouldthe belt break in service. If signs of oilcontamination are found, trace the source ofthe oil leak, and rectify it. Wash down theengine timing belt area and all relatedcomponents, to remove all traces of oil.

Refitting10 Prior to refitting, thoroughly clean thetiming belt sprockets. Check that thetensioner pulley rotates freely, without anysign of roughness. If necessary, renew thetensioner pulley as described in Section 7.Make sure that the locking tools are still inplace, as described in Section 3.11 Manoeuvre the timing belt into position,ensuring the arrows on the belt are pointing inthe direction of rotation (clockwise, whenviewed from the right-hand end of the engine).12 Do not twist the timing belt sharply whilerefitting it. Fit the belt over the crankshaft andcamshaft sprockets. Make sure that the “frontrun” of the belt is taut - ie, ensure that anyslack is on the tensioner pulley side of thebelt. Fit the belt over the coolant pumpsprocket and tensioner pulley. Ensure that thebelt teeth are seated centrally in thesprockets.13 Loosen the tensioner pulley retaining nut.Pivot the pulley anti-clockwise to remove allfree play from the timing belt, then retightenthe nut. Tension the timing belt as describedunder the relevant sub-heading.

Tensioning without the specialelectronic measuring toolNote: If this method is used, ensure that thebelt tension is checked by a Peugeot dealer atthe earliest possible opportunity.14 Peugeot dealers use a special tool totension the timing belt. A similar tool may befabricated using a suitable square-section barattached to an arm made from a metal strip; ahole should be drilled in the strip at a distanceof 80 mm from the centre of the square-section bar. Fit the tool to the hole in the

tensioner pulley, keeping the tool arm as closeto the horizontal as possible, and hang a 1.5kg (3.3 lb) weight (aluminium block engine) or2.0 kg (4.4 lb) weight (cast-iron block engine)from the hole in the tool (see illustration). Inthe absence of an object of the specifiedweight, a spring balance can be used to exertthe required force, ensuring that the springbalance is held at 90° to the tool arm. Slackenthe pulley retaining nut, allowing the weight orforce exerted (as applicable) to push thetensioner pulley against the belt, thenretighten the pulley nut.15 If this special tool is not available, anapproximate setting may be achieved bypivoting the tensioner pulley anti-clockwiseuntil it is just possible to twist the timing beltthrough 90° by finger and thumb, midwaybetween the crankshaft and camshaftsprockets. The deflection of the belt at themid-point between the sprockets should beapproximately 6.0 mm.16 Remove the locking tools from thecamshaft sprocket and flywheel.17 Using a suitable socket and extension baron the crankshaft sprocket bolt, rotate thecrankshaft through four complete rotations ina clockwise direction (viewed from the right-hand end of the engine). Do not at any timerotate the crankshaft anti-clockwise.18 Slacken the tensioner pulley nut, re-tension the belt as described in paragraph 14or 15, then tighten the tensioner pulley nut tothe specified torque.19 Rotate the crankshaft through a furthertwo turns clockwise, and check that both thecamshaft sprocket and flywheel timing holesare still correctly aligned.20 If all is well, refit the timing belt covers asdescribed in Section 5, and reconnect thebattery negative terminal.

Tensioning using the specialelectronic measuring tool21 Fit the special belt tensioning measuringequipment to the “front run” of the timing belt,approximately midway between the camshaftand crankshaft sprockets. Position thetensioner pulley so that the belt is tensionedto a setting of 45 units, then retighten itsretaining nut.22 Remove the locking tools from thecamshaft sprocket and flywheel, and removethe measuring tool from the belt.23 Using a suitable socket and extension baron the crankshaft sprocket bolt, rotate thecrankshaft through four complete rotations ina clockwise direction (viewed from the right-hand end of the engine). Do not at any timerotate the crankshaft anti-clockwise.24 Slacken the tensioner pulley retaining nut,and refit the measuring tool to the belt. If a“new” belt is being fitted, tension it to asetting of 40 units. If an “old” belt is being re-used, tighten it to a setting of 36 units. Note:Peugeot state that a belt becomes “old” after1 hour’s use. With the belt correctlytensioned, tighten the pulley retaining nut tothe specified torque.25 Remove the measuring tool from the belt,then rotate the crankshaft through anothertwo complete rotations in a clockwisedirection, so that both the camshaft sprocketand flywheel timing holes are realigned. Donot at any time rotate the crankshaft anti-clockwise. Fit the measuring tool to the belt,and check the belt tension. A “new” beltshould give a reading of 51 ± 3 units; an “old”belt should be 45 ± 3 units.26 If the belt tension is incorrect, repeat theprocedures in paragraphs 24 and 25.27 With the belt tension correctly set, refit thetiming belt covers as described in Section 5,and reconnect the battery negative terminal.

7 Timing belt tensioner andsprockets - removal,inspection and refitting

4Note: This Section describes the removal andrefitting of the components concerned asindividual operations. If more than one of themis to be removed at the same time, start byremoving the timing belt as described inSection 6; remove the actual component asdescribed below, ignoring the preliminarydismantling steps.

Removal1 Disconnect the battery negative terminal.2 Position the engine assembly/valve timingholes as described in Section 3, and lock boththe camshaft sprocket and flywheel inposition. Do not attempt to rotate the enginewhilst the pins are in position.

4 Loosen the timing belt tensioner pulleyretaining nut. Rotate the pulley in a clockwisedirection, using a suitable square-section keyfitted to the hole in the pulley hub, thenretighten the retaining nut.5 Disengage the timing belt from thesprocket, and move the belt clear, taking carenot to bend or twist it sharply. Remove thelocking pin from the camshaft sprocket.6 Slacken the camshaft sprocket retainingbolt and remove it, along with its washer. Toprevent the camshaft rotating as the bolt isslackened, a sprocket-holding tool will berequired. In the absence of the specialPeugeot tool, an acceptable substitute can befabricated as follows. Use two lengths of steelstrip (one long, the other short), and three nutsand bolts; one nut and bolt forms the pivot ofa forked tool, with the remaining two nuts andbolts at the tips of the “forks” to engage withthe sprocket spokes as shown in theaccompanying “Tool Tip”. Do not attempt touse the sprocket locking pin to prevent thesprocket from rotating whilst the bolt isslackened.7 With the retaining bolt removed, slide thesprocket off the end of the camshaft. If thelocating peg is a loose fit in the rear of thesprocket, remove it for safe-keeping. Examinethe camshaft oil seal for signs of oil leakageand, if necessary, renew it as described inSection 8.

Crankshaft sprocket8 Remove the centre and lower timing beltcovers as described in Section 5.9 Remove the timing belt from the sprocketsas described in Section 6.10 To prevent crankshaft rotation whilst thesprocket retaining bolt is slackened, select4th gear, and have an assistant apply thebrakes firmly. If the engine has been removedfrom the vehicle, lock the flywheel ring gear,using an arrangement similar to that shown(see illustration). Do not be tempted to usethe flywheel locking pin to prevent thecrankshaft from rotating; temporarily removethe locking pin from the rear of the flywheelprior to slackening the pulley bolt, then refit itonce the bolt has been slackened. Do notallow the crankshaft to turn more than a fewdegrees while loosening the bolt otherwisethe pistons may touch the valves.11 Unscrew the retaining bolt and washer,then slide the sprocket off the end of thecrankshaft (see illustrations). Refit thelocating pin to the rear of the timing hole in therear of the flywheel.12 If the Woodruff key is a loose fit in thecrankshaft, remove it and store it with thesprocket for safe-keeping. If necessary, alsoslide the flanged spacer off the end of thecrankshaft (see illustration). Examine thecrankshaft oil seal for signs of oil leakage and,if necessary, renew it (refer to Section 14).

Tensioner pulley13 Remove the centre timing belt cover asdescribed in Section 5.

14 Slacken and remove the timing belttensioner pulley retaining nut, and slide thepulley off its mounting stud. Examine themounting stud for signs of damage and, ifnecessary, renew it.

Inspection15 Clean the sprockets thoroughly, andrenew any that show signs of wear, damageor cracks.16 Clean the tensioner assembly, but do notuse any strong solvent which may enter thepulley bearing. Check that the pulley rotatesfreely about its hub, with no sign of stiffnessor free play. Renew the tensioner pulley ifthere is any doubt about its condition, or ifthere are any obvious signs of wear ordamage.

RefittingCamshaft sprocket17 Refit the locating peg (where removed) tothe rear of the sprocket, then locate thesprocket on the end of the camshaft. Ensurethat the locating peg is correctly engaged withthe cutout in the camshaft end.18 Refit the sprocket retaining bolt andwasher. Tighten the bolt to the specifiedtorque, whilst retaining the sprocket with thetool used on removal (see Tool Tip).19 Realign the timing hole in the camshaftsprocket (see Section 3) with thecorresponding hole in the cylinder head, andrefit the locking pin.20 Refit the timing belt to the camshaftsprocket. Ensure that the “front run” of the

belt is taut - ie, ensure that any slack is on thetensioner pulley side of the belt. Do not twistthe belt sharply while refitting it, and ensurethat the belt teeth are seated centrally in thesprockets.21 Loosen the tensioner pulley retaining nut.Rotate the pulley anti-clockwise to remove allfree play from the timing belt, then retightenthe nut.22 Tension the belt as described inparagraphs 14 to 19 of Section 6.23 Refit the timing belt covers as describedin Section 5.

Tensioner pulley31 Refit the tensioner pulley to its mountingstud, and fit the retaining nut.32 Ensure that the “front run” of the belt istaut - ie, ensure that any slack is on the pulleyside of the belt. Check that the belt is centrallylocated on all its sprockets. Rotate the pulleyanti-clockwise to remove all free play from thetiming belt, then tighten the pulley retainingnut securely.33 Tension the belt as described inparagraphs 14 to 19 of Section 6.34 Refit the timing belt covers as describedin Section 5.

8 Camshaft oil seal - renewal 4Note: If the camshaft oil seal is to be renewedwith the timing belt still in place, check firstthat the belt is free from oil contamination.(Renew the belt as a matter of course if signsof oil contamination are found; see Section 6.)Cover the belt to protect it from oilcontamination while work is in progress.Ensure that all traces of oil are removed fromthe area before the belt is refitted.1 Remove the camshaft sprocket asdescribed in Section 7.2 Punch or drill two small holes oppositeeach other in the oil seal. Screw a self-tappingscrew into each, and pull on the screws withpliers to extract the seal.3 Clean the seal housing, and polish off anyburrs or raised edges, which may havecaused the seal to fail in the first place.4 Lubricate the lips of the new seal with cleanengine oil, and drive it into position until it

seats on its locating shoulder. Use a suitabletubular drift, such as a socket, which bearsonly on the hard outer edge of the seal. Takecare not to damage the seal lips during fitting.Note that the seal lips should face inwards.5 Refit the camshaft sprocket as described inSection 7.

9 Valve clearances - checkingand adjustment 3

Note: The valve clearances must be checkedand adjusted only when the engine is cold.1 The importance of having the valveclearances correctly adjusted cannot beoverstressed, as they vitally affect theperformance of the engine. If the clearancesare too big, the engine will be noisy (charac-teristic rattling or tapping noises) and engineefficiency will be reduced, as the valves opentoo late and close too early. A more seriousproblem arises if the clearances are too small,however. If this is the case, the valves may notclose fully when the engine is hot, resulting inserious damage to the engine (eg. burnt valveseats and/or cylinder head warping/cracking).The clearances are checked and adjusted asfollows.2 Remove the cylinder head cover and oilbaffle plate as described in Section 4.3 The engine can now be turned using asuitable socket and extension bar fitted to thecrankshaft sprocket/pulley bolt.

4 It is important that the clearance of eachvalve is checked and adjusted only when thevalve is fully closed, with the rocker armresting on the heel of the cam (directlyopposite the peak). This can be ensured bycarrying out the adjustments in the followingsequence, noting that No 1 cylinder is at thetransmission end of the engine. The correctvalve clearances are given in the Specifica-tions at the start of this Chapter. The valvelocations can be determined from the positionof the manifolds.

Valve fully Adjust valvesopenNo 1 exhaust No 3 inlet and No 4 exhaustNo 3 exhaust No 4 inlet and No 2 exhaustNo 4 exhaust No 2 inlet and No 1 exhaustNo 2 exhaust No 1 inlet and No 3 exhaust

5 With the relevant valve fully open, check theclearances of the two valves specified.Clearances are checked by inserting a feelerblade of the correct thickness between thevalve stem and the rocker arm adjustingscrew. The feeler blade should be a light,sliding fit. If adjustment is necessary, slackenthe adjusting screw locknut, and turn the

screw as necessary. Once the correctclearance is obtained, hold the adjustingscrew and securely tighten the locknut.Recheck the valve clearance, and adjustagain if necessary.6 Rotate the crankshaft until the next valve inthe sequence is fully open, and check theclearances of the next two specified valves.7 Repeat the procedure until all eight valveclearances have been checked (and ifnecessary, adjusted), then refit the oil baffleplate and cylinder head cover as described inSection 4.

10 Camshaft and rocker arms -removal, inspection andrefitting

4General information1 The rocker arm assembly is secured to thetop of the cylinder head by the cylinder headbolts. Although in theory, it is possible to undothe head bolts and remove the rocker armassembly without removing the head, inpractice, this is not recommended. Once thebolts have been removed, the head gasket willbe disturbed, and the gasket will almostcertainly leak or blow after refitting. For thisreason, removal of the rocker arm assemblycannot be done without removing the cylinderhead and renewing the head gasket.2 The camshaft is slid out of the right-handend of the cylinder head, and it thereforecannot be removed without first removing thecylinder head, due to a lack of clearance.

Removal

Rocker arm assembly3 Remove the cylinder head as described inSection 11.4 To dismantle the rocker arm assembly,carefully prise off the circlip from the right-hand end of the rocker shaft; retain the rockerpedestal, to prevent it being sprung off theend of the shaft. Slide the variouscomponents off the end of the shaft, keepingall components in their correct fitted order(see illustration). Make a note of eachcomponent’s correct fitted position andorientation as it is removed, to ensure it isfitted correctly on reassembly.

5 To separate the left-hand pedestal andshaft, first unscrew the cylinder head coverretaining stud from the top of the pedestal;this can be achieved using a stud extractor, oralternatively, by using two nuts lockedtogether. With the stud removed, unscrew thegrub screw from the top of the pedestal, andcarefully withdraw the rocker shaft (seeillustrations).

Camshaft6 Remove the cylinder head as described inSection 11.7 With the head on a bench, remove thelocking pin, then remove the camshaftsprocket as described in paragraphs 6 and 7of Section 7.8 Unbolt the housing from the left-hand endof the cylinder head, then undo the retainingbolt, and remove the camshaft thrust forkfrom the cylinder head (see illustration).9 Using a large flat-bladed screwdriver,carefully prise the oil seal out of the right-hand end of the cylinder head, then carefullyslide out the camshaft (see illustrations).Discard the seal - a new one must be used onrefitting.

Inspection

Rocker arm assembly10 Examine the rocker arm bearing surfaceswhich contact the camshaft lobes for wearridges and scoring. Renew any rocker armson which these conditions are apparent. If arocker arm bearing surface is badly scored,also examine the corresponding lobe on thecamshaft for wear, as it is likely that both willbe worn. Renew worn components asnecessary. The rocker arm assembly can bedismantled as described in paragraphs 4 and 5.11 Inspect the ends of the (valve clearance)adjusting screws for signs of wear or damage,and renew as required.12 If the rocker arm assembly has beendismantled, examine the rocker arm and shaftbearing surfaces for wear ridges and scoring.If there are obvious signs of wear, the relevantrocker arm(s) and/or the shaft must berenewed.

Camshaft13 Examine the camshaft bearing surfacesand cam lobes for signs of wear ridges andscoring. Renew the camshaft if any of theseconditions are apparent. Examine the conditionof the bearing surfaces, both on the camshaftjournals and in the cylinder head. If the headbearing surfaces are worn excessively, thecylinder head will need to be renewed. If thenecessary measuring equipment is available,camshaft bearing journal wear can be checkedby direct measurement, noting that No 1journal is at the transmission end of the head.14 Examine the thrust fork for signs of wearor scoring, and renew as necessary.

Refitting

Rocker arm assembly15 If the rocker arm assembly wasdismantled, refit the rocker shaft to the left-hand pedestal, aligning its locating hole withthe pedestal threaded hole. Refit the grubscrew, and tighten it securely. With the grubscrew in position, refit the cylinder head covermounting stud to the pedestal, and tighten itsecurely. Apply a smear of clean engine oil tothe shaft, then slide on all removedcomponents, ensuring each is correctly fittedin its original position. Once all componentsare in position on the shaft, compress theright-hand pedestal and refit the circlip.Ensure that the circlip is correctly located inits groove on the shaft.16 Refit the cylinder head and rocker armassembly as described in Section 11.

Camshaft17 Ensure that the cylinder head andcamshaft bearing surfaces are clean, thenliberally oil the camshaft bearings and lobes.Slide the camshaft back into position in thecylinder head. On carburettor engines, takecare that the fuel pump operating lever is nottrapped by the camshaft as it is slid intoposition. To prevent this, remove the fuelpump before refitting the camshaft, then refitit afterwards.18 Locate the thrust fork with the left-handend of the camshaft. Refit the fork retainingbolt, tightening it to the specified torquesetting.19 Ensure that the housing and cylinder headmating surfaces are clean and dry, then applya smear of sealant to the housing matingsurface. Refit the housing to the left-hand endof the head, and securely tighten its retainingbolts.20 Lubricate the lips of the new seal withclean engine oil, then drive it into position untilit seats on its locating shoulder. Use asuitable tubular drift, such as a socket, whichbears only on the hard outer edge of the seal.Take care not to damage the seal lips duringfitting. Note that the seal lips should faceinwards.21 Refit the camshaft sprocket as describedin paragraphs 17 to 19 of Section 7.22 Refit the cylinder head as described inSection 11.

Ensure that the belt is notbent or twisted sharply.13 Slacken the retaining clips, anddisconnect the coolant hoses from thethermostat housing (on the left-hand end ofthe cylinder head).14 Depress the retaining clip(s), anddisconnect the wiring connector(s) from theelectrical switch and/or sensor(s) which arescrewed into the thermostat housing/cylinderhead (as appropriate). Also where necessary,release the TDC connector from its supporton the distributor bracket on the left-hand endof the cylinder head.

Carburettor models15 Disconnect the LT wiring connectors fromthe distributor and HT coil. Release the TDCsensor wiring connector from the side of thecoil mounting bracket, and disconnect thevacuum pipe from the distributor vacuumdiaphragm unit. If the cylinder head is to bedismantled for overhaul, remove thedistributor and ignition HT coil as described inChapter 5. If the cylinder numbers are notalready marked on the HT leads, number eachlead, to avoid the possibility of the leads beingincorrectly connected on refitting. Disconnectthe HT leads from the spark plugs, andremove the distributor cap and leadassembly.

Fuel-injected models16 Disconnect the wiring connector from theignition HT coil. If the cylinder head is to bedismantled for overhaul, remove the ignitionHT coil as described in Chapter 5. If thecylinder numbers are not already marked onthe HT leads, number each lead, to avoid thepossibility of the leads being incorrectlyconnected on refitting. Note that the HT leadsshould be disconnected from the spark plugsinstead of the coil, and the coil and leadsremoved as an assembly.

All models17 Slacken and remove the bolt securing theengine oil dipstick tube to the cylinder head.18 Working in the reverse of the sequenceshown in illustration 11.38a, progressivelyslacken the ten cylinder head bolts by half aturn at a time, until all bolts can be unscrewedby hand.19 With all the cylinder head bolts removed,lift the rocker arm assembly off the cylinderhead. Note the locating pins which are fittedto the base of each rocker arm pedestal. Ifany pin is a loose fit in the head or pedestal,remove it for safe-keeping.20 On engines with a cast-iron cylinder

block, lift the cylinder head away; seekassistance if possible, as it is a heavyassembly, especially if it is being removedcomplete with the manifolds.21 On engines with an aluminium cylinderblock, the joint between the cylinder head andgasket and the cylinder block/crankcase mustnow be broken without disturbing the wetliners. To break the joint, obtain two L-shapedmetal bars which fit into the cylinder head boltholes. Gently “rock” the cylinder head freetowards the front of the car (see illustration).Do not try to swivel the head on the cylinderblock/crankcase; it is located by dowels, aswell as by the tops of the liners. Note: If careis not taken and the liners are moved, there isalso a possibility of the bottom seals beingdisturbed, causing leakage after refitting thehead. When the joint is broken, lift the cylinderhead away; seek assistance if possible, as it isa heavy assembly, especially if it is beingremoved complete with the manifolds.22 On all models, remove the gasket fromthe top of the block, noting the two locatingdowels. If the locating dowels are a loose fit,remove them and store them with the head forsafe-keeping. Do not discard the gasket - onsome models it will be needed for identifi-cation purposes (see paragraphs 28 and 29).Caution: On aluminium block engines, donot attempt to rotate the crankshaft withthe cylinder head removed, otherwise thewet liners may be displaced. Operationsthat require the rotation of the crankshaft(eg cleaning the piston crowns), shouldonly be carried out once the cylinder linersare firmly clamped in position. In theabsence of the special Peugeot linerclamps, the liners can be clamped inposition using large flat washerspositioned underneath suitable-lengthbolts. Alternatively, the original head boltscould be temporarily refitted, with suitablespacers fitted to their shanks.23 If the cylinder head is to be dismantled foroverhaul, remove the camshaft as describedin Section 10, then refer to Part C of thisChapter.

Preparation for refitting24 The mating faces of the cylinder head andcylinder block/crankcase must be perfectlyclean before refitting the head. Use a hard

2A•10 TU engine in-car repair procedures

11.21 Using two angled metal rods to freethe cylinder head from the block

plastic or wood scraper to remove all traces ofgasket and carbon; also clean the pistoncrowns. Refer to paragraph 23 before turningthe crankshaft on aluminium block engines.Take particular care during the cleaningoperations, as aluminium alloy is easilydamaged. Also, make sure that the carbon isnot allowed to enter the oil and waterpassages - this is particularly important for thelubrication system, as carbon could block theoil supply to the engine’s components. Usingadhesive tape and paper, seal the water, oiland bolt holes in the cylinderblock/crankcase. To prevent carbon enteringthe gap between the pistons and bores,smear a little grease in the gap. After cleaningeach piston, use a small brush to remove alltraces of grease and carbon from the gap,then wipe away the remainder with a cleanrag. Clean all the pistons in the same way.25 Check the mating surfaces of the cylinderblock/crankcase and the cylinder head fornicks, deep scratches and other damage. Ifslight, they may be removed carefully with afile, but if excessive, machining may be theonly alternative to renewal.26 If warpage of the cylinder head gasketsurface is suspected, use a straight-edge tocheck it for distortion. Refer to Part C of thisChapter if necessary.27 When purchasing a new cylinder headgasket, it is essential that a gasket of thecorrect thickness is obtained. On somemodels only one thickness of gasket isavailable, so this is not a problem. However,on all other models, there are two differentthicknesses available - the standard gasketwhich is fitted at the factory, and a slightlythicker “repair” gasket (+ 0.2 mm), for useonce the head gasket face has beenmachined. If the cylinder head has beenmachined, it should have the letter “R”stamped adjacent to the No 3 exhaust port,and the gasket should also have the letter “R”stamped adjacent to No 3 cylinder on its frontupper face. The gaskets can also be identifiedas described in the following paragraph, usingthe cut-outs on the left-hand end of thegasket.28 With the gasket fitted the correct way upon the cylinder block, there will be a singlecut-out, or no cut-out at all, at the rear of the

left-hand side of the gasket identifying theengine type (ie. TU engine). In the centre ofthe gasket there may be another series ofbetween 0 and 4 cut-outs, identifying themanufacturer of the gasket and whether ornot it contains asbestos (these cut-outs are oflittle importance). The important cut-outlocation is at the front of the gasket; on thestandard gasket there will be no cut-out in thisposition, whereas on the thicker “repair”gasket there will be a single cut-out (seeillustration). Identify the gasket type, andensure that the new gasket obtained is of thecorrect thickness. If there is any doubt as towhich gasket is fitted, take the old gasketalong to your Peugeot dealer, and have himconfirm the gasket type.29 Check the condition of the cylinder headbolts, and particularly their threads, wheneverthey are removed. Wash the bolts in suitablesolvent, and wipe them dry. Check each forany sign of visible wear or damage, renewingany bolt if necessary. Measure the length ofeach bolt, to check for stretching (althoughthis is not a conclusive test, in the event thatall ten bolts have stretched by the sameamount). Although Peugeot do not actuallyspecify that the bolts must be renewed, it is

strongly recommended that the bolts shouldbe renewed as a complete set whenever theyare disturbed.30 On aluminium block engines, prior torefitting the cylinder head, check the cylinderliner protrusion as described in Part C of thisChapter.

Refitting31 Wipe clean the mating surfaces of thecylinder head and cylinder block/crankcase.Check that the two locating dowels are inposition at each end of the cylinderblock/crankcase surface and, if necessary,remove the cylinder liner clamps.32 Position a new gasket on the cylinderblock/crankcase surface, ensuring that itsidentification cut-outs are at the left-hand endof the gasket (see illustration) and themanufacturer’s name is uppermost.33 Check that the flywheel and camshaftsprocket are still correctly locked in positionwith their respective tools then, with the aid ofan assistant, carefully refit the cylinder headassembly to the block, aligning it with thelocating dowels (see illustration).34 Ensure that the locating pins are inposition in the base of each rocker pedestal,then refit the rocker arm assembly to thecylinder head (see illustration).35 Apply a smear of grease to the threads,and to the underside of the heads, of thecylinder head bolts. Peugeot recommend theuse of Molykote G Rapid Plus grease(available from your Peugeot dealer - a sachetis supplied with the top-end gasket set); in theabsence of the specified grease, a good-quality high-melting-point grease may beused.36 Carefully enter each bolt into its relevanthole (do not drop them in) and screw in, byhand only, until finger-tight.37 Working progressively and in thesequence shown, tighten the cylinder headbolts to their Stage 1 torque setting, using atorque wrench and suitable socket (seeillustrations).38 Once all the bolts have been tightened totheir Stage 1 setting, working again in thegiven sequence, angle-tighten the boltsthrough the specified Stage 2 angle, using asocket and extension bar. It is recommended

that an angle-measuring gauge is used duringthis stage of the tightening, to ensureaccuracy (see illustration). If a gauge is notavailable, use white paint to make alignmentmarks between the bolt head and cylinderhead prior to tightening; the marks can thenbe used to check that the bolt has beenrotated through the correct angle duringtightening.39 On cast-iron block engines, it will then benecessary to tighten the bolts through thespecified Stage 3 angle setting.40 With the cylinder head bolts correctlytightened, refit the dipstick tube retaining boltand tighten it securely.41 Refit the timing belt to the camshaftsprocket. Ensure that the “front run” of thebelt is taut - ie, ensure that any slack is on thetensioner pulley side of the belt. Do not twistthe belt sharply while refitting it, and ensurethat the belt teeth are seated centrally in thesprockets.42 Loosen the tensioner pulley retaining nut.Pivot the pulley anti-clockwise to remove allfree play from the timing belt, then retightenthe nut.43 Tension the belt as described under therelevant sub-heading in Section 6, then refitthe centre and upper timing belt covers asdescribed in Section 5.

Carburettor models44 If the head was stripped for overhaul, refitthe distributor and HT coil as described inChapter 5, ensuring that the HT leads arecorrectly reconnected. If the head was notstripped, reconnect the wiring connector andvacuum pipe to the distributor, and the HTlead to the coil; clip the TDC sensor wiringconnector onto the coil bracket.

Fuel-injected models45 If the head was stripped for overhaul, refitthe ignition HT coil and leads as described inChapter 5, ensuring that the leads arecorrectly reconnected. If the head was notstripped, simply reconnect the wiringconnector to the HT coil.

All models46 Reconnect the wiring connector(s) to thecoolant switch/sensor(s) on the left-hand endof the head.

47 Reconnect the coolant hoses to thethermostat housing, securely tightening theirretaining clips.48 Working as described in the relevant Partof Chapter 4, carry out the following tasks:a) Refit all disturbed wiring, hoses and

control cable(s) to the inlet manifold andfuel system components.

b) On carburettor models, reconnect andadjust the choke and accelerator cables.

c) On fuel injection models, reconnect andadjust the accelerator cable.

d) Reconnect the exhaust system front pipeto the manifold. Where applicable,reconnect the lambda sensor wiringconnector.

e) Refit the air cleaner housing and inletduct.

49 Check and, if necessary, adjust the valveclearances as described in Section 9.50 On completion, reconnect the battery,and refill the cooling system as described inChapter 1.

12 Sump - removal and refitting 2Removal1 Firmly apply the handbrake, then jack upthe front of the vehicle and support it on axlestands (see “Jacking and Vehicle Support”).Disconnect the battery negative lead.

2 Drain the engine oil, then clean and refit theengine oil drain plug, tightening it to thespecified torque. If the engine is nearing itsservice interval when the oil and filter are duefor renewal, it is recommended that the filter isalso removed, and a new one fitted. Afterreassembly, the engine can then be refilledwith fresh oil. Refer to Chapter 1 for furtherinformation.3 Remove the exhaust system front pipe asdescribed in the relevant Part of Chapter 4.4 Progressively slacken and remove all thesump retaining nuts and bolts. On cast-ironblock engines, it may be necessary to unboltthe flywheel cover plate from the transmissionto gain access to the left-hand sump bolts.5 Break the joint by striking the sump with thepalm of your hand, then lower the sump andwithdraw it from underneath the vehicle (seeillustration).6 While the sump is removed, take theopportunity to check the oil pump pick-up/strainer for signs of clogging or splitting. Ifnecessary, remove the pump as described inSection 13, and clean or renew the strainer.

Refitting7 Clean all traces of sealant from the matingsurfaces of the cylinder block/crankcase andsump, then use a clean rag to wipe out thesump and the engine’s interior.8 Ensure that the sump and cylinderblock/crankcase mating surfaces are cleanand dry, then apply a coating of suitablesealant to the sump mating surface.9 Offer up the sump, locating it on itsretaining studs, and refit its retaining nuts andbolts. Tighten the nuts and bolts evenly andprogressively to the specified torque.10 Refit the exhaust front pipe as describedin the relevant Part of Chapter 4.11 Replenish the engine oil (see Chapter 1).

securing the oil pump in position (seeillustration). Disengage the pump sprocketfrom the chain, and remove the oil pump. Ifthe pump locating dowel is a loose fit, removeand store it with the retaining bolts for safe-keeping.

Inspection3 Examine the oil pump sprocket for signs ofdamage and wear such as chipped or missingteeth. If the sprocket is worn, the pumpassembly must be renewed, as the sprocket isnot available separately. It is alsorecommended that the chain and drivesprocket, fitted to the crankshaft, is renewed atthe same time. On aluminium block engines,renewal of the chain and drive sprocket is aninvolved operation requiring the removal of themain bearing ladder, and therefore cannot becarried out with the engine still fitted to thevehicle. On cast-iron block engines, the oilpump drive sprocket and chain can beremoved with the engine in situ, once thecrankshaft sprocket has been removed and thecrankshaft oil seal housing has been unbolted.Refer to Part D for further information.4 Slacken and remove the bolts securing thestrainer cover to the pump body, then lift offthe strainer cover. Remove the relief valvepiston and spring (and guide pin - cast-ironblock engines only), noting which way roundthey are fitted.5 Examine the pump rotors and body forsigns of wear ridges and scoring. If worn, thecomplete pump assembly must be renewed.6 Examine the relief valve piston for signs ofwear or damage, and renew if necessary. Thecondition of the relief valve spring can only bemeasured by comparing it with a new one; ifthere is any doubt about its condition, itshould also be renewed. Both the piston andspring are available individually.7 Thoroughly clean the oil pump strainer witha suitable solvent, and check it for signs ofclogging or splitting. If the strainer isdamaged, the strainer and cover assemblymust be renewed.8 Locate the relief valve spring, piston and(where fitted) the guide pin in the strainercover, then refit the cover to the pump body.Align the relief valve piston with its bore in thepump. Refit the cover retaining bolts,tightening them securely.

Refitting9 Ensure that the locating dowel is inposition, then engage the pump sprocket withits drive chain. Locate the pump on its doweland refit the pump retaining bolts, tighteningthem to the specified torque setting.10 Refit the sump as described in Section 12.

14 Crankshaft oil seals - renewal 4Right-hand oil seal1 Remove the crankshaft sprocket andflanged spacer as described in Section 7.Secure the timing belt clear of the workingarea, so that it cannot be contaminated withoil. Make a note of the correct fitted depth ofthe seal in its housing.2 Punch or drill two small holes oppositeeach other in the seal. Screw a self-tappingscrew into each, and pull on the screws withpliers to extract the seal. Alternatively, the sealcan be levered out of position using a suitableflat-bladed screwdriver, taking great care notto damage the crankshaft shoulder or sealhousing (see illustration).3 Clean the seal housing, and polish off anyburrs or raised edges, which may havecaused the seal to fail in the first place.4 Lubricate the lips of the new seal with cleanengine oil, and carefully locate the seal on theend of the crankshaft. Note that its sealing lipmust face inwards. Take care not to damagethe seal lips during fitting.5 Using a suitable tubular drift (such as asocket) which bears only on the hard outeredge of the seal, tap the seal into position, tothe same depth in the housing as the originalwas prior to removal. The inner face of theseal must end up flush with the inner wall ofthe crankcase.6 Wash off any traces of oil, then refit thecrankshaft sprocket as described in Section 7.

Left-hand oil seal7 Remove the flywheel (see Section 15).8 Make a note of the correct fitted depth ofthe seal in its housing. Punch or drill two smallholes opposite each other in the seal. Screw a

self-tapping screw into each, and pull on thescrews with pliers to extract the seal.9 Clean the seal housing, and polish off anyburrs or raised edges, which may havecaused the seal to fail in the first place.10 Lubricate the lips of the new seal withclean engine oil, and carefully locate the sealon the end of the crankshaft.11 Using a suitable tubular drift, which bearsonly on the hard outer edge of the seal, drivethe seal into position, to the same depth in thehousing as the original was prior to removal.12 Wash off any traces of oil, then refit theflywheel as described in Section 15.

15 Flywheel - removal, inspectionand refitting 3

Removal1 Remove the transmission (Chapter 7A),then remove the clutch assembly (Chapter 6).2 Prevent the flywheel from turning by lockingthe ring gear teeth with a similar arrangementto that shown in illustration 7.10. Alternatively,bolt a strap between the flywheel and thecylinder block/crankcase. Do not attempt tolock the flywheel in position using the lockingpin described in Section 3.3 Slacken and remove the flywheel retainingbolts, and discard them; they must berenewed whenever they are disturbed.4 Remove the flywheel. Do not drop it, as it isvery heavy. If the locating dowel is a loose fitin the crankshaft end, remove and store it withthe flywheel for safe-keeping.

Inspection5 If the flywheel’s clutch mating surface isdeeply scored, cracked or otherwisedamaged, the flywheel must be renewed.However, it may be possible to have itsurface-ground; seek the advice of a Peugeotdealer or engine reconditioning specialist.6 If the ring gear is badly worn or has missingteeth, it must be renewed. This job is best leftto a Peugeot dealer or engine reconditioningspecialist. The temperature to which the newring gear must be heated for installation iscritical and, if not done accurately, thehardness of the teeth will be destroyed.

Refitting7 Clean the mating surfaces of the flywheeland crankshaft. Remove any remaininglocking compound from the threads of thecrankshaft holes, using the correct-size tap, ifavailable.

If a suitable tap is notavailable, cut two slots intothe threads of one of the oldflywheel bolts and use the

bolt to remove the locking compoundfrom the threads.

8 If the new flywheel retaining bolts are notsupplied with their threads already pre-coated, apply a suitable thread-lockingcompound to the threads of each bolt.9 Ensure that the locating dowel is inposition. Offer up the flywheel, locating it onthe dowel, and fit the new retaining bolts.10 Lock the flywheel using the methodemployed on dismantling, and tighten theretaining bolts to the specified torque.11 Refit the clutch as described in Chapter 6.Remove the locking tool, and refit thetransmission as described in Chapter 7A.

16 Engine/transmissionmountings - inspection andrenewal 2

Inspection1 If improved access is required, raise thefront of the car and support it securely on axlestands (see “Jacking and Vehicle Support”).2 Check the mounting rubber to see if it iscracked, hardened or separated from themetal at any point; renew the mounting if anysuch damage or deterioration is evident.3 Check that all the mounting’s fasteners aresecurely tightened; use a torque wrench tocheck if possible.4 Using a large screwdriver or a crowbar,check for wear in the mounting by carefullylevering against it to check for free play.Where this is not possible, enlist the aid of anassistant to move the engine/transmissionback and forth, or from side to side, while youwatch the mounting. While some free play isto be expected even from new components,excessive wear should be obvious. Ifexcessive free play is found, check first thatthe fasteners are correctly secured, thenrenew any worn components as describedbelow.

2B•4 XU engine in-car repair procedures

1 General information

How to use this ChapterThis Part of Chapter 2 describes those

repair procedures that can reasonably becarried out on the XU series petrol engine,while it remains in the car. If the engine hasbeen removed from the car and is beingdismantled as described in Part C, anypreliminary dismantling procedures can beignored. Refer to Part A for information on theTU series petrol engine.

Note that, while it may be possiblephysically to overhaul items such as thepiston/connecting rod assemblies while theengine is in the car, such tasks are not usuallycarried out as separate operations. Usually,several additional procedures (not to mentionthe cleaning of components and oilways) haveto be carried out. For this reason, all suchtasks are classed as major overhaulprocedures, and are described in Part C ofthis Chapter.

Part C describes the removal of theengine/transmission from the vehicle, and thefull overhaul procedures that can then becarried out.

XU series engine descriptionThe XU series engine is a well-proven

engine which has been fitted to manyprevious Peugeot and Citroën vehicles. Theengine is of the in-line 4-cylinder type,mounted transversely at the front of the car.The clutch and transmission are attached toits left-hand end. The 405 range is availablewith 1580 cc (8-valve), 1761 cc (8-valve), 1905 cc (8- and 16-valve), and 1998 cc (8- and 16-valve) versions of the XU seriesengine. The 1905 cc and 1998 cc 16-valveengines are of the DOHC (double overheadcamshaft) type; all the others are SOHC(single overhead camshaft) engines.

The crankshaft runs in five main bearings.Thrustwashers are fitted to No 2 main bearingcap, to control crankshaft endfloat.

The connecting rods rotate on horizontally-split bearing shells at their big-ends. Thepistons are attached to the connecting rodsby gudgeon pins. On 16-valve models, thegudgeon pins are a sliding fit in theconnecting rod, and are secured with circlips.On all other models, they are an interferencefit in the connecting rod small-end eyes. Thealuminum alloy pistons have three rings - two compression rings and an oil control ring.

On 1580 cc, 1761 cc and 1905 cc (both 8-and 16-valve) models, the cylinder block is of

the “wet-liner” type. The cylinder block is castin aluminium alloy, and the bores havereplaceable cast-iron liners that are locatedfrom their top ends. Sealing O-rings are fittedat the base of each liner, to prevent theescape of coolant into the sump.

On all 1998 cc models (both 8- and 16-valve), the engine is of the conventional“dry-liner” type. The cylinder block is cast iniron, and no separate bore liners are fitted.

On 16-valve models, both inlet and exhaustcamshafts are driven by a toothed timing belt.The camshafts operate the sixteen valves viaself-adjusting hydraulic tappets (fitted to thecam followers), thus eliminating the need tomanually adjust the valve clearances. Bothcamshafts run in bearing caps which arebolted to the top of the cylinder head. Theinlet and exhaust valves are each closed bycoil springs, and operate in guides pressedinto the cylinder head.

On 8-valve models, the camshaft is drivenby a toothed timing belt, and it operates theeight valves via followers located beneatheach cam lobe. The valve clearances areadjusted by shims, positioned between thefollowers and the tip of the valve stem. Thecamshaft runs in bearing caps which arebolted to the top of the cylinder head. Theinlet and exhaust valves are each closed bycoil springs, and operate in guides pressed

into the cylinder head. Both the valve seatsand guides can be renewed separately ifworn.

On all models, the water pump is driven bythe timing belt.

Lubrication is by means of an oil pumpwhich is driven (via a chain and sprocket) offthe crankshaft right-hand end. It draws oilthrough a strainer located in the sump, andthen forces it through an externally-mountedfilter into galleries in the cylinderblock/crankcase. From there, the oil isdistributed to the crankshaft (main bearings)and camshaft. The big-end bearings aresupplied with oil via internal drillings in thecrankshaft; the camshaft bearings alsoreceive a pressurised supply. The camshaftlobes and valves are lubricated by splash, asare all other engine components. On 16-valvemodels, an oil cooler is mounted beneath theoil filter cartridge, to keep the oil temperatureconstant under severe operating conditions.The oil cooler is supplied with coolant fromthe engine cooling system.

Throughout the manual, it is oftennecessary to identify the engines not only bytheir cubic capacity, but also by their enginecode. The engine code consists of threeletters (eg. RFY). On 1.6, 1.8 and 1.9 litremodels the code is stamped on a plateattached to the front, left-hand end of thecylinder block, and on 2.0 litre models theengine code is stamped directly onto the frontface of the cylinder block, on the machinedsurface located just to the left of the oil filter(next to the crankcase vent hose union).

3 Engine assembly/valvetiming holes - generalinformation and usage

3Note: Do not attempt to rotate the enginewhilst the crankshaft/camshaft are locked inposition. If the engine is to be left in this statefor a long period of time, it is a good idea toplace suitable warning notices inside thevehicle, and in the engine compartment. Thiswill reduce the possibility of the engine beingaccidentally cranked on the starter motor,which is likely to cause damage with thelocking pins in place.1 On all models, timing holes are drilled in thecamshaft sprocket(s) and crankshaft pulley.The holes are used to align the crankshaft andcamshaft(s), to prevent the possibility of thevalves contacting the pistons when refittingthe cylinder head, or when refitting the timingbelt. When the holes are aligned with theircorresponding holes in the cylinder head andcylinder block (as appropriate), suitablediameter pins can be inserted to lock both thecamshaft and crankshaft in position,preventing them rotating unnecessarily.Proceed as follows.2 Remove the timing belt upper cover asdescribed in Section 6.3 Apply the handbrake, jack up the front ofthe car and support it on axle stands (see“Jacking and Vehicle Support”). Remove theright-hand front roadwheel.4 From underneath the front of the car, priseout the two retaining clips and remove theplastic cover from the wing valance, to gainaccess to the crankshaft pulley bolt. Wherenecessary, unclip the coolant hoses from thebracket, to improve access further. Thecrankshaft can then be turned using a suitablesocket and extension bar fitted to the pulleybolt. Note that the crankshaft must always beturned in a clockwise direction (viewed fromthe right-hand side of vehicle).

16-valve models5 Rotate the crankshaft pulley until the timingholes in both camshafts are aligned with theircorresponding holes in the cylinder head. Theholes are aligned when the inlet camshaftsprocket hole is in the 8 o’clock position, andthe exhaust camshaft sprocket is in the 6o’clock position, when viewed from the right-hand end of the engine.6 With the camshaft sprocket holes correctlypositioned, insert a 6 mm diameter bolt (or adrill of suitable size), through the timing hole inthe crankshaft pulley, and locate it in thecorresponding hole in the end of the cylinderblock. Note that it may be necessary to rotate

the crankshaft slightly, to get the holes toalign.7 With the crankshaft pulley locked inposition, insert a 6 mm diameter bolt (or a drill)through the timing hole in each camshaftsprocket, and locate it in the cylinder head.Note that the special Peugeot locking pins areactually 8 mm in diameter, with only their endsstepped down to 6 mm to locate in thecylinder head (see illustration). To simulatethis, wrap insulation tape around the outerend of the bolt or drill, to build it up until it is asnug fit in the camshaft hole.8 The crankshaft and camshafts are nowlocked in position, preventing unnecessaryrotation.

All other models9 Rotate the crankshaft pulley until the timinghole in the camshaft sprocket is aligned withits corresponding hole in the cylinder head.Note that the hole is aligned when thesprocket hole is in the 8 o’clock position,when viewed from the right-hand end of theengine.10 On early 1580 cc and 1905 cc modelshaving a semi-automatic timing belt tensioner,a 10 mm diameter bolt (or a drill of suitablesize) will be required to lock the crankshaftpulley in position.11 On later 1580 cc and 1905 cc models,and all 1761 and 1998 cc 8-valve models(which have a manually-adjusted timing belttensioner pulley) the pulley can be locked inposition with an 8 mm diameter bolt or drill.The special Peugeot locking pin is actually 10mm in diameter, with only its end steppeddown to 8 mm to locate in the cylinder block.To simulate this, wrap insulation tape aroundthe outer end of the bolt/drill, to build it upuntil it is a snug fit in the pulley hole.12 With the camshaft sprocket holescorrectly positioned, insert the required bolt ordrill through the timing hole in the crankshaftpulley, and locate it in the corresponding holein the end of the cylinder block. Note that itmay be necessary to rotate the crankshaftslightly, to get the holes to align.13 With the crankshaft pulley locked inposition, insert the appropriate bolt or drillthrough the timing hole in the camshaft

The later typeof gasket can be identified from its grey colour(the earlier type of gasket was colouredblack). The later type gasket can be fitted toearlier engines, but the following proceduremust be followed when fitting the later typegasket to any engine.

a) Apply silicon sealant to the corners ofNos 1 and 5 camshaft bearing caps, thenafter refitting the cover tighten thesecuring bolts to the Stage 1 torquewrench setting in the order shown (seeillustrations).

b) Start the engine, and run it at idle speedfor 10 minutes with the bonnet closed.

c) Open the bonnet and check for leaks. Ifevident, do not tighten the bolts further,but remove the cover to establish thecause, then repeat the fitting operations.

d) Allow the engine to cool for 4 hours, then

tighten the ten outer cover bolts to theStage 2 torque wrench setting in theorder shown (see illustration). Thisprocedure allows for the settling of thegasket, which takes place due to the heatproduced by the engine.

7 Timing belt - generalinformation, removal andrefitting

4Note: Peugeot specify the use of a specialelectronic tool (SEEM C.TRONIC belttensioning measuring tool) to correctly set thetiming belt tension on all 1992-on models. Ifaccess to this equipment cannot be obtained,an approximate setting can be achieved usingthe method described below. In this case, thetension must be checked using the specialelectronic tool at the earliest opportunity. Donot drive the vehicle over large distances, oruse high engine speeds, until the belt tension isknown to be correct. Refer to a Peugeot dealerfor advice.

6.24 Timing belt upper (outer) coverretaining clip (arrowed) - 1998 cc 16-valve models

General information1 The timing belt drives the camshaft(s) andcoolant pump from a toothed sprocket on thefront of the crankshaft. If the belt breaks orslips in service, the pistons are likely to hit thevalve heads, resulting in extensive (andexpensive) damage.2 The timing belt should be renewed at thespecified intervals (see Chapter 1), or earlier if itis contaminated with oil, or if noisy in operation(a “scraping” noise due to uneven wear).3 If the timing belt is being removed, it is awise precaution to check the condition of thecoolant pump at the same time (check forsigns of coolant leakage). This may avoid theneed to remove the timing belt again at a laterstage, should the coolant pump fail.

RemovalEarly (pre-1992) 1580 cc and 1905 cc8-valve models with a semi-automaticbelt tensioner4 Disconnect the battery negative terminal.5 Align the engine assembly/valve timingholes as described in Section 3, and lock thecamshaft sprocket and crankshaft pulley inposition. Do not attempt to rotate the enginewhilst the pins are in position.6 Remove the centre and lower timing beltcovers as described in Section 6.7 Slacken (but do not remove) the two nutssecuring the tensioner assembly to the end ofthe cylinder block (see illustration). Loosenthe tensioner cam spindle locknut, located onthe rear of cylinder block flange.8 Using a suitable open-ended spanner onthe square-section end of the tensioner camspindle, rotate the cam until the tensionerspring is fully compressed and the belttension is relieved (see illustration). Hold thecam in this position, and tighten the locknut.9 If required for improved access to thetiming belt, remove the right-hand enginemounting bracket as follows: Place a jackbeneath the engine, with a block of wood onthe jack head. Raise the jack until it issupporting the weight of the engine.10 Slacken and remove the three nutssecuring the engine/transmission right-handmounting bracket to the engine bracket.Remove the single nut securing the bracket tothe mounting rubber, and lift off the bracket.

Undo the three bolts securing the enginebracket to the end of the cylinder head/block,and remove the bracket.11 If the timing belt is to be re-used, usewhite paint or chalk to mark the direction ofrotation on the belt (if markings do not alreadyexist), then slip the belt off the sprockets.Note that the crankshaft must not be rotatedwhilst the belt is removed.12 Check the timing belt carefully for anysigns of uneven wear, splitting, or oilcontamination. Pay particular attention to theroots of the teeth. Renew it if there is theslightest doubt about its condition. If theengine is undergoing an overhaul, and hascovered more than 36 000 miles (60 000 km)with the existing belt fitted, renew the belt as amatter of course, regardless of its apparentcondition. The cost of a new belt is nothingcompared with the cost of repairs, should thebelt break in service. If signs of oilcontamination are found, trace the source ofthe oil leak and rectify it. Wash down theengine timing belt area and all relatedcomponents, to remove all traces of oil.

Refitting

Early (pre-1992) 1580 cc and 1905 ccmodels with a semi-automatic belttensioner30 Before refitting, thoroughly clean thetiming belt sprockets. Check that thetensioner pulley rotates freely, without anysign of roughness. If necessary, renew thetensioner pulley as described in Section 8.31 Ensure that the camshaft sprocket lockingpin is still in position. Temporarily refit thecrankshaft pulley, and insert the locking pinthrough the pulley timing hole to ensure thatthe crankshaft is still correctly positioned.32 Remove the crankshaft pulley. Manoeuvrethe timing belt into position, ensuring that anyarrows on the belt are pointing in the directionof rotation (clockwise when viewed from theright-hand end of the engine).33 Do not twist the timing belt sharply whilerefitting it. Fit the belt over the crankshaft andcamshaft sprockets. Ensure that the belt“front run” is taut - ie, any slack should be onthe tensioner pulley side of the belt. Fit thebelt over the water pump sprocket andtensioner pulley. Ensure that the belt teeth areseated centrally in the sprockets.34 Slacken the tensioner cam spindlelocknut, and check that the tensioner pulley isforced against the timing belt by springpressure.35 Refit the crankshaft pulley, tightening itsretaining bolt by hand only.36 Rotate the crankshaft through at least twocomplete rotations in a clockwise direction(viewed from the right-hand end of theengine). Realign the camshaft and crankshaftengine assembly/valve timing holes (seeSection 3). Do not at any time rotate thecrankshaft anti-clockwise. Both camshaft andcrankshaft timing holes should be aligned sothat the locking pins can be easily inserted.This indicates that the valve timing is correct.37 If the timing holes are not correctlypositioned, release the tensioner assembly asdescribed in paragraph 8, and disengage thebelt from the camshaft sprocket. Rotate thecamshaft and crankshaft slightly as requireduntil both locking pins are in position.Relocate the timing belt on the camshaftsprocket. Ensure that the belt “front run” istaut - ie, that any slack is on the tensionerpulley side of the belt. Slacken the tensionerlocknut, then remove the locking pins andrepeat the procedure in paragraph 36.38 Once both timing holes are correctlyaligned, tighten the two tensioner assemblyretaining nuts to the specified torque. Tighten

the tensioner cam spindle locknut to itsspecified torque.39 With the belt correctly installed andtensioned, where removed refit the enginebracket to the side of the cylinder head/block,and securely tighten its retaining bolts. Refitthe right-hand mounting bracket, and tightenits retaining nuts to the specified torque. Thejack can then be removed from underneaththe engine.40 Remove the crankshaft pulley, then refitthe timing belt covers (refer to Section 6).41 Install the crankshaft pulley (Section 5),and reconnect the battery negative terminal.

Later (1992-on) 1580 cc and 1905 cc(8-valve) models with a manually-adjusted belt tensioner pulley, and all1761 cc and 1998 cc (8-valve) modelsNote: Peugeot specify the use of a specialelectronic tool (SEEM C. TRONIC belt tensionmeasuring tool) to correctly set the timing belttension. If this equipment is not available, anapproximate setting can be achieved usingthe method described below. If this method isused, however, the belt tension must bechecked using the special electronic tool atthe earliest possible opportunity. Do not drivethe vehicle over large distances, or use highengine speeds, until the belt tension is knownto be correct. Refer to a Peugeot dealer foradvice.42 Install the timing belt as described abovein paragraphs 30 to 33.43 Loosen the tensioner pulley retaining bolt.Using the square-section key, pivot the pulleyanti-clockwise to remove all free play from thetiming belt.44 If the special belt tension measuringequipment is available, it should be fitted tothe “front run” of the timing belt. The tensionerroller should be adjusted so that the initial belttension is 16 ± 2 units on 1998 cc 8-valvemodels, and 30 ± 2 units on all other models.45 Tighten the pulley retaining bolt to thespecified torque. Refit the crankshaft pulleyagain, tightening its bolt by hand only.46 Carry out the operations described inparagraph 36 (and where necessary, para-graph 37, ignoring the information about thetensioner) to ensure both timing holes arecorrectly aligned and the valve timing is correct.47 If the tension is being set without usingthe special measuring tool, proceed asfollows. Check that, under moderate pressurefrom the thumb and forefinger, the belt canjust be twisted through 90° at the mid-point ofthe “front run” of the belt. Note that thismethod is only an initial setting, and the belttension must checked at the earliest availableopportunity using the special measuring tool.Failure to do so could lead to the beltbreaking (through over-tightening) or slipping(through slackness), resulting in seriousengine damage. If necessary, readjust thetensioner pulley position as required. Tightenits retaining bolt to the specified torque oncompletion.

48 If the special measuring tool is beingused, the final belt tension on the “front run”of the belt on all models should be 44 ± 2units. Readjust the tensioner pulley positionas required, then retighten the retaining bolt tothe specified torque. Rotate the crankshaftthrough a further two rotations clockwise, andrecheck the tension. Repeat this procedure asnecessary until the correct tension reading isobtained after rotating the crankshaft.49 With the belt tension correctly set, on1580 cc, 1761 cc and 1905 cc models, whereremoved refit the engine bracket to the side ofthe cylinder head/block, and securely tightenits retaining bolts. Refit the right-hand enginemounting bracket, and tighten its retainingnuts to the specified torque. The jack can thenbe removed from underneath the engine.50 On all models, remove the crankshaftpulley, then refit the timing belt cover(s) asdescribed in Section 6.51 Refit the crankshaft pulley (Section 5), andreconnect the battery negative terminal.

1905 cc 16-valve modelsNote: Peugeot specify the use of a specialelectronic tool (SEEM belt tension measuringtool) to correctly set the timing belt tension. Ifthis equipment is not available, anapproximate setting can be achieved usingthe method described below. If this method isused, however, the tension must be checkedusing the special electronic tool at the earliestpossible opportunity. Do not drive the vehicleover large distances, or use high enginespeeds, until the belt tension is known to becorrect.

55 Note that there may be timing marks onthe belt, in the form of yellow lines, to ensure itis correctly positioned on both camshaftsprockets and the crankshaft sprocket. Thetwo single-line timing marks should be alignedwith the timing dot (directly opposite thesprocket timing hole) on each camshaftsprocket. The double-line timing mark shouldbe aligned with the crankshaft sprocket,where it will be directly opposite the sprocketWoodruff key slot. Peugeot state that the useof these timing marks is optional, but they areuseful in helping to ensure that the valvetiming is correctly set at the first attempt.56 With the three locking pins in position,move both the front and rear tensioner pulleystowards the timing belt until both pulleys arecontacting the belt. Securely tighten theretaining bolts.57 If the tension is being set without the useof the special measuring tool, proceed asfollows. Using the square-section key fitted tothe hole in the tensioner backplate, move thefront tensioner pulley against the belt until allfree play is removed from the belt. Hold thetensioner in this position, and tighten thepulley retaining bolts to the specified torque.Similarly move the rear tensioner pulleyagainst the belt and tighten the bolt.58 If the special belt tension measuringequipment is available, it should be fitted tothe “front run” of the timing belt, between thefront tensioner and the camshaft sprocket.Move the front tensioner pulley anti-clockwiseso that the belt is tensioned to a setting of 19units, then tighten the retaining bolt to thespecified torque setting.59 Slacken the rear tensioner pulley retainingbolt. Using the square-section key, pivot thepulley clockwise until the belt tension on the“front run” is 21 units. Hold the tensioner inposition, and tighten its retaining bolt to thespecified torque setting.60 Remove the locking pins from thecamshaft and crankshaft sprockets and,where fitted, the tensioning measuring devicefrom the belt.61 Rotate the crankshaft through at least twocomplete rotations in a clockwise direction(viewed from the right-hand end of theengine). Realign the camshaft and crankshaftengine assembly/valve timing holes (seeSection 3). Do not at any time rotate thecrankshaft anti-clockwise. Both camshafttiming holes and the crankshaft timing holeshould be correctly positioned so that thelocking pins can be easily inserted, indicatingthat the valve timing is correct.62 If the timing holes are not correctlypositioned, repeat the tensioning procedure.63 Once the valve timing is correctly set,remove the locking pins and recheck the belttension.64 If the tension is being set without thespecial measuring tool, proceed as follows.Check that, under moderate pressure fromthe thumb and forefinger, the belt can just betwisted through 45°, at the mid-point between

the camshaft sprocket and tensioner pulley onthe “front run” of the belt. Note that thismethod is only an initial setting, and the belttension must be checked at the earliestavailable opportunity using the specialmeasuring tool. Failure to do so could lead tothe belt breaking (through over-tightening) orslipping (through slackness), resulting inserious engine damage.65 If the special measuring tool is beingused, the final belt tension on the “front run”of the belt, between the camshaft sprocketand tensioner pulley, should be 45 ± 5 units.Repeat the procedure as necessary, until thecorrect tension reading is obtained after thecrankshaft has been rotated.66 Once the belt tension is correctly set, refitthe timing belt covers as described in Section 6. Refit the crankshaft pulley asdescribed in Section 5, and reconnect thebattery negative terminal

1998 cc 16-valve modelsNote: Peugeot specify the use of a specialelectronic tool (SEEM belt tension measuringtool) to correctly set the timing belt tension. Ifthis equipment is not available, anapproximate setting can be achieved usingthe method described below. If this method isused, however, the tension must be checkedusing the special electronic tool at the earliestpossible opportunity. Do not drive the vehicleover large distances, or use high enginespeeds, until the belt tension is known to becorrect. Refer to a Peugeot dealer for advice.67 Before refitting, thoroughly clean thetiming belt sprockets. Check that eachtensioner pulley rotates freely, without anysign of roughness. If necessary, renew thetensioner pulley(s) as described in Section 8.68 Ensure that the camshaft and crankshaftsprocket locking pins are still in position.Slacken the tensioner mounting bolts so thatthey are free to pivot easily.69 Manoeuvre the timing belt into position,ensuring that any arrows on the belt arepointing in the direction of rotation (clockwisewhen viewed from the right-hand end of theengine).70 Note that there are also timing marks onthe belt, in the form of yellow lines, to ensure itis correctly positioned on both camshaftsprockets and the crankshaft sprocket. Thetwo single-line timing marks should be alignedwith the timing dot (directly opposite thesprocket timing hole) on each camshaftsprocket. The double-line timing mark shouldbe aligned with the crankshaft sprocket,where it will be directly opposite the sprocketWoodruff key slot. Peugeot state that the useof these timing marks is optional, but they areuseful in helping to ensure that the valvetiming is correctly set at the first attempt.71 With the three locking pins in position,move both the front and rear tensioner pulleystowards the timing belt until both pulleys arecontacting the belt. Securely tighten the reartensioner retaining bolt.

72 If the tension is being set without the useof the special measuring tool, proceed asfollows. Using the square-section key fitted tothe hole in the tensioner backplate, move thefront tensioner pulley against the belt until allfree play is removed from the belt. Hold thetensioner in this position, and tighten thepulley retaining bolts to the specified torque.73 If the special belt tension measuringequipment is available, it should be fitted tothe “front run” of the timing belt, between thefront tensioner and the camshaft sprocket.Move the tensioner pulley backplate so thatthe belt is initially over-tensioned to a settingof 45 units, then back the tensioner off untilthe belt tension is 22 ± 2 units. Hold thebackplate in this position, and tighten both thetensioner pulley retaining bolts to thespecified torque.74 Slacken the rear tensioner pulley retainingbolt. Using the square-section key, pivot thepulley anti-clockwise until all free play isremoved from the belt. If the belt tensionmeasuring equipment is being used, set thetensioner pulley so that the belt tension on the“front run” is 32 ± 2 units. Hold the tensionerin position, and tighten its retaining bolt to thespecified torque setting.75 Remove the locking pins from thecamshaft and crankshaft sprockets and,where fitted, the tensioning measuring devicefrom the belt.76 Rotate the crankshaft through at least twocomplete rotations in a clockwise direction(viewed from the right-hand end of theengine). Realign the camshaft and crankshaftengine assembly/valve timing holes (seeSection 3). Do not at any time rotate thecrankshaft anti-clockwise. Both camshafttiming holes and the crankshaft timing holeshould be correctly positioned so that thelocking pins can be easily inserted, indicatingthat the valve timing is correct.77 If the timing holes are not correctlypositioned, slacken the tensioner assemblyretaining bolts, and disengage the belt fromthe camshaft sprockets. Rotate the camshaftsand crankshaft slightly as required until alllocking pins are in position, then relocate thetiming belt on the camshaft sprocket. Ensurethat the belt “top run” and “front run” are taut- ie, ensure that any slack is on the reartensioner pulley and water pump side of thebelt. Repeat the tensioning procedure until thevalve timing is correct.78 Once the valve timing is correctly set,remove the locking pins and recheck the belttension.79 If the tension is being set without thespecial measuring tool, proceed as follows.Check that, under moderate pressure fromthe thumb and forefinger, the belt can just betwisted through 45°, at the mid-point betweenthe camshaft sprocket and tensioner pulley onthe “front run” of the belt. Note that thismethod is only an initial setting, and the belttension must be checked at the earliestavailable opportunity using the special

measuring tool. Failure to do so could lead tothe belt breaking (through over-tightening) orslipping (through slackness), resulting inserious engine damage. If necessary, readjustthe rear tensioner pulley position as required,and tighten its retaining bolt to the specifiedtorque.80 If the special measuring tool is beingused, the final belt tension on the “front run”of the belt, between the camshaft sprocketand tensioner pulley, should be 53 ± 2 units.Readjust the rear tensioner pulley position asrequired, then retighten the retaining bolt tothe specified torque. Rotate the crankshaftthrough a further two rotations clockwise, andrecheck the tension. Repeat this procedure asnecessary, until the correct tension reading isobtained after the crankshaft has beenrotated.81 Once the belt tension is correctly set, refitthe timing belt covers (see Section 6). Refit thecrankshaft pulley as described in Section 5,and reconnect the battery negative terminal

8 Timing belt tensioner andsprockets - removal,inspection and refitting

4Note: This Section describes the removal andrefitting of the components concerned asindividual operations - if more than one is tobe removed at the same time, start byremoving the timing belt as described inSection 7; remove the actual component asdescribed below, ignoring the preliminarydismantling steps.

Removal1 Disconnect the battery negative lead.2 Align the engine assembly/valve timingholes as described in Section 3, locking thecamshaft sprocket(s) and the crankshaftpulley in position, and proceed as describedunder the relevant sub-heading. Do notattempt to rotate the engine whilst the pinsare in position.

Loosen the tensioner camspindle locknut, located on the rear of cylinderblock flange.5 Using a suitable open-ended spanner onthe square-section end of the tensioner camspindle, rotate the cam until the tensionerspring is fully compressed and the belttension is relieved. Hold the cam in thisposition, and securely tighten the locknut.6 Remove the locking pin from the camshaftsprocket. Disengage the timing belt from thesprocket and position it clear, taking care notto bend or twist the belt sharply.

7 Slacken the camshaft sprocket retainingbolt and remove it, along with its washer. Toprevent the camshaft rotating as the bolt isslackened, a sprocket holding tool will berequired. In the absence of the specialPeugeot tool, an acceptable substitute can befabricated from two lengths of steel strip (onelong, the other short) and three nuts and bolts,as follows. One nut and bolt forms the pivot ofa forked tool, with the remaining two nuts andbolts at the tips of the “forks” to engage withthe sprocket spokes, as shown in illustration8.39. Do not attempt to use the sprocketlocking pin to prevent the sprocket fromrotating whilst the bolt is slackened.8 With the retaining bolt removed, slide thesprocket off the end of the camshaft. If thelocating peg is a loose fit in the rear of thesprocket, remove it for safe-keeping. Examinethe camshaft oil seal for signs of oil leakageand, if necessary, renew it as described inSection 9.

Inspection39 Clean the camshaft/crankshaft sprocketsthoroughly, and renew any that show signs ofwear, damage or cracks.40 Clean the tensioner assembly, but do notuse any strong solvent which may enter thepulley bearing. Check that the pulley rotatesfreely on the backplate, with no sign ofstiffness or free play. Renew the assembly ifthere is any doubt about its condition, or if

there are any obvious signs of wear ordamage.41 On early 1580 cc and 1905 cc models, thetensioner spring should also be carefullychecked, as its condition is critical for thecorrect tensioning of the timing belt. The onlyway to check the spring tension is to compareit with a new one; if there is any doubt as to itscondition, the spring should be renewed.

1905 cc 16-valve models3 Unbolt the plastic cover from over thepower steering pump drive pulley.4 Disconnect the drivebelt from the powersteering drive pulley with reference to Chapter 1.5 Unscrew the bolt and remove the pulleyfrom the end of the exhaust camshaft.6 Remove both camshaft sprockets asdescribed in Section 8.7 Remove the distributor cap and rotor armwith reference to Chapter 5A. 8 Unbolt and remove the rotor arm supportand the sealing disc.9 Unbolt the inner timing belt cover from theside of the cylinder head.10 Carefully ease the oil supply pipe out fromthe top of the camshaft bearing caps, andremove it. Note the O-ring seals fitted to eachof the pipe unions.11 Turn each camshaft so that the sprocketkey grooves are approximately at the 3o’clock position.12 Evenly and progressively slacken thecamshaft bearing cap retaining screws by oneturn at a time. This will relieve the valve springpressure on the bearing caps gradually andevenly. Once the pressure has been relieved,the bolts can be fully unscrewed andremoved.13 Lift off the bearing caps, noting thecorrect fitted location of the locating dowels.If the dowels are a loose fit, remove them andstore them with the bearing caps for safe-keeping.14 Lift the camshafts out of the cylinderhead, and slide the oil seals off the camshaftends. Identify each camshaft for position - onearly models the inlet camshaft is identified bythe distributor drive keyway.15 Obtain sixteen small, clean plasticcontainers, and number them 1 to 16. Using arubber sucker, withdraw each cam follower inturn, invert it to prevent oil loss, and place it inits respective container. The container shouldthen be filled with clean engine oil. Do notinterchange the cam followers, or the rate ofwear will be much-increased. Do not allowthem to lose oil, or the hydraulic tappetmechanism will take a long time to refill withoil on restarting the engine, resulting inincorrect valve clearances.

numbered 1 to 5, number 1 being at thetransmission end of the engine. If not, makeidentification marks on the caps, using whitepaint or a suitable marker pen.20 Working in the reverse of the sequenceshown in illustration 10.54, evenly andprogressively slacken the camshaft bearingcap retaining screws by one turn at a time.This will relieve the valve spring pressure onthe bearing caps gradually and evenly. Oncethe pressure has been relieved, the bolts canbe fully unscrewed and removed.21 Lift off the bearing caps, noting thecorrect fitted location of the locating dowels.If the dowels are a loose fit, remove them andstore them with the bearing caps for safe-keeping.22 Lift the camshafts out of the cylinderhead, and slide the oil seals off the camshaftends. The inlet camshaft can be identified bythe braking system vacuum pump drive slot inits left-hand end; therefore, there is no need tomark the camshafts for identification.23 Obtain sixteen small, clean plasticcontainers, and number them 1 to 16. Using arubber sucker, withdraw each cam follower inturn, invert it to prevent oil loss, and place it inits respective container. The container shouldthen be filled with clean engine oil. Do notinterchange the cam followers, or the rate ofwear will be much-increased. Do not allowthem to lose oil, or the hydraulic tappetmechanism will take a long time to refill withoil on restarting the engine, resulting inincorrect valve clearances.

All other models24 Remove the camshaft sprocket asdescribed in Section 8.25 On models with a distributor, remove thedistributor as described in Chapter 5. Makesure the recessed socket-headed screw isremoved from the distributor housing.26 On models with a carburettor, remove thefuel pump as described in Chapter 4.27 On models with a static (distributorless)ignition system, remove the ignition HT coil asdescribed in Chapter 5.28 With the distributor or coil removed (asapplicable), slacken the upper bolt securingthe thermostat housing to the left-hand end ofthe cylinder head. Remove the bolt, along with

its sealing washer. This is necessary since thebolt screws into the left-hand (No 1) camshaftbearing cap.29 Carefully ease the oil supply pipe out fromthe top of the camshaft bearing caps, andremove it. Note the O-ring seals fitted to eachof the pipe unions on later models.30 The camshaft bearing caps should benumbered 1 to 5, number 1 being at thetransmission end of the engine. If not, makeidentification marks on the caps, using whitepaint or a suitable marker pen. Also markeach cap in some way to indicate its correctfitted orientation. This will avoid the possibilityof installing the caps the wrong way aroundon refitting.31 Evenly and progressively slacken thecamshaft bearing cap retaining nuts by oneturn at a time. This will relieve the valve springpressure on the bearing caps gradually andevenly. Once the pressure has been relieved,the nuts can be fully unscrewed and removed(see illustration).32 Note the correct fitted orientation of thebearing caps, then remove them from cylinderhead (see illustration).33 Lift the camshaft away from the cylinderhead, and slide the oil seal off the camshaftend (see illustration).34 Obtain eight small, clean plasticcontainers, and number them 1 to 8;alternatively, divide a larger container intoeight compartments. Using a rubber sucker,withdraw each follower in turn, and place it inits respective container. Do not interchangethe cam followers, or the rate of wear will bemuch-increased. If necessary, also removethe shim from the top of the valve stem, andstore it with its respective follower. Note thatthe shim may stick to the inside of the followeras it is withdrawn. If this happens, take carenot to allow it to drop out as the follower isremoved.

Inspection35 Examine the camshaft bearing surfacesand cam lobes for signs of wear ridges andscoring. Renew the camshaft if any of theseconditions are apparent. Examine thecondition of the bearing surfaces, both on thecamshaft journals and in the cylinderhead/bearing caps. If the head bearing

surfaces are worn excessively, the cylinderhead will need to be renewed. If suitablemeasuring equipment is available, camshaftbearing journal wear can be checked by directmeasurement (where the necessary specifica-tions have been quoted by Peugeot), notingthat No 1 journal is at the transmission end ofthe head.36 Examine the cam follower bearingsurfaces which contact the camshaft lobes forwear ridges and scoring. Renew any followeron which these conditions are apparent. If afollower bearing surface is badly scored, alsoexamine the corresponding lobe on thecamshaft for wear, as it is likely that both willbe worn. Renew worn components asnecessary.37 On 16-valve models, if the engine’s valveclearances have sounded noisy, particularly ifthe noise persists after initial start-up fromcold, there is reason to suspect a faultyhydraulic tappet mechanism. Only a goodmechanic experienced in these engines cantell whether the noise level is typical, or ifrenewal of one or more of the tappets iswarranted. If a faulty hydraulic tappet isdiagnosed and the engine’s service history isunknown, it is always worth trying the effect ofrenewing the engine oil and filter before goingto the expense of renewing any of the camfollowers. Use only good-quality engine oil ofthe recommended viscosity and specification(Chapter 1). It is not possible to overhaul thehydraulic tappet mechanism, so if anytappet’s operation is faulty, it must berenewed.38 On earlier 1580 cc and 1905 cc models,inspect the camshaft thrust fork (fitted to theside of No 5 camshaft bearing cap) for signsof wear or scoring, and if necessary renew it(see illustrations). The fork is retained by asingle bolt; on refitting, ensure that the bolt issecurely tightened. On later models, the thrustfork is no longer fitted, and the camshaftendfloat is controlled by the camshaft bearingcap.

11 Valve clearances - checkingand adjustment 3

Checking

16-valve models1 On 1905 cc and 1998 cc 16-valve models,the valve clearances are automaticallyadjusted by the hydraulic tappet mechanism

fitted to each cam follower. Therefore it is notnecessary, or indeed possible, to check oradjust the valve clearances manually. If thevalve gear has become noisy, a faulty tappetmechanism should be suspected. Refer toSection 10 for further information.

All other models2 On these models, the importance of havingthe valve clearances correctly adjustedcannot be overstressed, as they vitally affectthe performance of the engine. Checkingshould not be regarded as a routine operation,however. It should only be necessary whenthe valve gear has become noisy, after engineoverhaul, or when trying to trace the cause ofpower loss. The clearances are checked asfollows. The engine must be cold for thecheck to be accurate.3 Apply the handbrake, then jack up the frontof the car and support it on axle stands (see“Jacking and Vehicle Support”). Remove theright-hand front roadwheel.4 From underneath the front of the car, priseout the two retaining clips, and remove theplastic cover from the wing valance to gainaccess to the crankshaft sprocket bolt. Wherenecessary, unclip the coolant hoses from thebracket to improve access further.5 The engine can now be turned over using asuitable socket and extension bar fitted to thecrankshaft pulley bolt.6 Remove the cylinder head cover asdescribed in Section 4.7 Draw the outline of the engine on a piece ofpaper, numbering the cylinders 1 to 4, with No 1 cylinder at the transmission end of theengine. Show the position of each valve,together with the specified valve clearance(see paragraph 11). Above each valve, drawtwo lines for noting (1) the actual clearanceand (2) the amount of adjustment required(see illustration).8 Turn the crankshaft until the inlet valve ofNo 1 cylinder (nearest the transmission end) is

fully closed, with the tip of the cam facingdirectly away from the cam follower.9 Using feeler blades, measure the clearancebetween the base of the cam and the follower(see illustration). Record the clearance online (1).10 Repeat the measurement for the otherseven valves, turning the crankshaft asnecessary so that the cam lobe in question isalways facing directly away from the relevantfollower.11 Calculate the difference between eachmeasured clearance and the desired value,and record it on line (2). Since the clearance isdifferent for inlet and exhaust valves, makesure that you are aware which valve you aredealing with. The valve sequence from eitherend of the engine is:

Ex - In - In - Ex - Ex - In - In - Ex12 If all the clearances are within tolerance,refit the cylinder head cover with reference toSection 4. Clip the coolant hoses into position(if removed) and refit the plastic cover to thewing valance. Refit the roadwheel, and lowerthe vehicle to the ground.13 If any clearance measured is outside thespecified tolerance, adjustment must becarried out as described in the followingparagraphs.

Adjustment

16-valve models14 See paragraph 1.

All other models15 Remove the camshaft as described inSection 10.16 Withdraw the first follower from thecylinder head, and recover the shim from thetop of the valve stem. Note that the shim maystick to the inside of the follower as it iswithdrawn. If this happens, take care not toallow it to drop out as the follower is removed.Remove all traces of oil from the shim, andmeasure its thickness with a micrometer (seeillustrations). The shims usually carrythickness markings, but wear may havereduced the original thickness.17 Refer to the clearance recorded for thevalve concerned. If the clearance was morethan that specified, the shim thickness mustbe increased by the difference recorded (2). If

the clearance was less than that specified, thethickness of the shim must be decreased bythe difference recorded (2).18 Draw three more lines beneath each valveon the calculation paper, as shown inillustration 11.7. On line (4), note themeasured thickness of the shim, then add ordeduct the difference from line (2) to give thefinal shim thickness required on line (5).19 Shims are available in thicknessesbetween 2.225 mm and 3.550 mm, in steps of0.025 mm. Clean new shims beforemeasuring or fitting them.20 Repeat the procedure given in paragraphs16 to 18 on the remaining valves, keepingeach follower identified for position.21 When reassembling, oil the shim, and fit iton the valve stem with the size marking facedownwards. Oil the follower, and lower it ontothe shim. Do not raise the follower after fitting,as the shim may become dislodged.22 When all the followers are in position,complete with their shims, refit the camshaftas described in Section 10. Recheck the valveclearances before refitting the cylinder headcover.

12 Cylinder head -removal and refitting 4

Removal1 Remove the battery and its mounting traywith reference to Chapter 5A.2 Drain the cooling system as described inChapter 1.3 Align the engine assembly/valve timingholes as described in Section 3, locking boththe camshaft sprocket and crankshaft pulleyin position, and proceed as described underthe relevant sub-heading. Do not attempt torotate the engine whilst the pins are inposition.

8-valve engines4 Remove the cylinder head cover asdescribed in Section 4, and remove the aircleaner mounting bracket from the rear ofcylinder head.5 Note that the following text assumes thatthe cylinder head will be removed with both

inlet and exhaust manifolds attached; this iseasier, but makes it a bulky and heavyassembly to handle. If it is wished first toremove the manifolds, proceed as describedin Chapter 4.6 Working as described in Chapter 4,disconnect the exhaust system front pipefrom the manifold. Where necessary,disconnect or release the lambda sensorwiring, so that it is not strained by the weightof the exhaust.7 Disconnect the following according tomodel, as described in Chapter 4:

a) On fuel injection models, depressurise thefuel system, and disconnect the fuel feedand return hoses. Plug all openings, toprevent loss of fuel and the entry of dirtinto the system.

b) On carburettor models remove thecarburettor and disconnect the fuel hosesfrom the fuel pump.

c) Disconnect the accelerator cable.d) Disconnect the vacuum servo unit

vacuum hose, coolant hose and all theother relevant vacuum/breather hoses,from the inlet manifold and on fuelinjection models the throttlebody/housing.

e) Undo the retaining nut, and position theoil filler neck clear of the inlet manifold.

f) On fuel injection models, disconnect thethree electrical connector plugs from thethrottle body.

g) On fuel injection models, disconnect thewiring connectors from the throttlepotentiometer and the fuel injectors, andfree the wiring loom from the manifold.

h) Where necessary, remove the idle speedauxiliary air valve.

8 Slacken the retaining clips, and disconnectthe coolant hoses from the thermostathousing (on the left-hand end of the cylinderhead).9 Depress the retaining clip(s), anddisconnect the wiring connector(s) from theelectrical switch(es) and/or sensor(s) whichare screwed into the thermostat housing, orinto the left-hand end of the cylinder head (asappropriate).10 Refer to Section 8 and disconnect thetiming belt from the camshaft sprocket; ifpreferred, completely remove the timing belt.

11 Jack up the front of the car and supporton axle stands (see “Jacking and VehicleSupport”).12 Unscrew and remove the horizontal boltfrom the engine rear mounting link beneaththe rear of the engine.13 Place a jack beneath the engine, with ablock of wood on the jack head. Raise thejack until it is supporting the weight of theengine.14 Slacken and remove the three nutssecuring the engine/transmission right-handmounting bracket to the engine bracket.Remove the single nut securing the bracket tothe mounting rubber, and lift off the bracket.Undo the three bolts securing the enginebracket to the end of the cylinder head/block,and remove the bracket.15 On models with a distributor, disconnectthe wiring connector from the ignition HT coil.If the cylinder head is to be dismantled foroverhaul, remove the distributor as describedin the relevant Sections of Chapter 5.Disconnect the HT leads from the spark plugs,and remove the distributor cap and leadassembly. If the cylinder numbers are notalready marked on the HT leads, number eachlead, to avoid the possibility of the leads beingincorrectly connected on refitting.16 On models with a static (distributorless)ignition system, disconnect the wiringconnector from the ignition HT coil. If thecylinder head is to be dismantled for overhaul,remove the ignition HT coil as described inChapter 5. Note that the HT leads should bedisconnected from the spark plugs instead ofthe coil, and the coil and leads removed as anassembly. If the cylinder numbers are notalready marked on the HT leads, number eachlead, to avoid the possibility of the leads beingincorrectly connected on refitting.17 Working in the reverse of the tighteningsequence, progressively slacken the tencylinder head bolts by half a turn at a time,until all bolts can be unscrewed by hand.Remove the bolts along with their washers,noting the correct location of the spacer fittedto the front left-hand bolt.18 With all the cylinder head bolts removed,the joint between the cylinder head andgasket and the cylinder block/crankcase mustnow be broken without disturbing the wetliners. Care must be taken on 1508 cc, 1761cc and 1905 cc engines to preventdisplacement of the wet liners; although theseliners are better-located and sealed thansome wet-liner engines, there is still a risk ofcoolant and foreign matter leaking into thesump if the cylinder head is lifted carelessly. Ifcare is not taken and the liners are moved,there is also a possibility of the bottom sealsbeing disturbed, causing leakage afterrefitting the head. This problem does notapply to 1998 cc engines as the liners areconventional and form part of the cylinderblock.19 To break the joint, obtain two L-shapedmetal bars which fit into the cylinder head bolt

holes, and gently “rock” the cylinder head freetowards the front of the car (see Part A). Onwet liner engines, do not try to swivel the headon the cylinder block/crankcase; it is locatedby dowels, as well as by the tops of the liners.20 When the joint is broken, lift the cylinderhead away. Seek assistance if possible, as itis a heavy assembly, especially if it iscomplete with the manifolds. Remove thegasket from the top of the block, noting thetwo locating dowels. If the locating dowels area loose fit, remove them and store them withthe head for safe-keeping. Do not discard thegasket; it will be needed for identificationpurposes.21 On wet liner engines, do not attempt toturn the crankshaft with the cylinder headremoved, otherwise the wet liners may bedisplaced. Operations that require thecrankshaft to be turned (eg cleaning thepiston crowns), should only be carried outonce the cylinder liners are firmly clamped inposition. In the absence of the specialPeugeot liner clamps, the liners can beclamped in position as follows. Use large flatwashers positioned underneath suitable-length bolts, or temporarily refit the originalhead bolts, with suitable spacers fitted to theirshanks (see illustration).22 If the cylinder head is to be dismantled foroverhaul, remove the camshaft as describedin Section 10, then refer to Part C of thisChapter.

1905 cc 16-valve engines23 Remove the cylinder head cover asdescribed in Section 4. Also remove the aircleaner inlet ducting.24 Unbolt the plastic cover from over thepower steering pump drive pulley.25 Disconnect the drivebelt from the powersteering drive pulley with reference to Chapter 1.26 Unscrew the bolt and remove the pulleyfrom the end of the exhaust camshaft.27 Identify all wiring connections on thecylinder head then disconnect them. Alsodisconnect the coolant hoses from the head.28 Remove the ignition coil as described inChapter 5.29 Remove the inlet manifold as described inChapter 4. To prevent damage to the radiator,position a piece of cardboard over it. On

models with air conditioning, disconnect theassociated wiring from the inlet manifold.30 Working as described in Chapter 4,disconnect the exhaust system front pipefrom the manifold.31 Place a jack beneath the engine, with ablock of wood on the jack head. Raise thejack until it is supporting the weight of theengine.32 Remove the right-hand engine mountingbracket with reference to Section 18.33 Remove the timing belt as described inSection 7.34 Working in the reverse of the tighteningsequence, progressively slacken the tencylinder head bolts by half a turn at a time,until all bolts can be unscrewed by hand.Remove the bolts along with their washers,noting the correct location of the spacer fittedto the front left-hand bolt.35 Release the end of the timing belt coverfrom the coolant pump using a screwdriver.36 With all the cylinder head bolts removed,the joint between the cylinder head andgasket and the cylinder block/crankcase mustnow be broken without disturbing the wetliners. Care must be taken to preventdisplacement of the wet liners. Although theseliners are better-located and sealed thansome wet-liner engines, there is still a risk ofcoolant and foreign matter leaking into thesump if the cylinder head is lifted carelessly. Ifcare is not taken and the liners are moved,there is also a possibility of the bottom sealsbeing disturbed, causing leakage afterrefitting the head.37 To break the joint, obtain two L-shapedmetal bars which fit into the cylinder head boltholes, and gently “rock” the cylinder head freetowards the front of the car (see Part A). Donot try to swivel the head on the cylinderblock/crankcase; it is located by dowels, aswell as by the tops of the liners. Take care notto damage the oil supply tubes when insertingthe metal bars - if necessary remove the tubesfirst.38 When the joint is broken, lift the cylinderhead away. Seek assistance if possible, as itis a heavy assembly. Remove the gasket fromthe top of the block, noting the two locatingdowels. If the locating dowels are a loose fit,remove them and store them with the head forsafe-keeping. Do not discard the gasket; it willbe needed for identification purposes.39 Do not attempt to turn the crankshaft withthe cylinder head removed, otherwise the wetliners may be displaced. Operations thatrequire the crankshaft to be turned (egcleaning the piston crowns), should only becarried out once the cylinder liners are firmlyclamped in position. In the absence of thespecial Peugeot liner clamps, the liners canbe clamped in position as follows. Use largeflat washers positioned underneath suitable-length bolts, or temporarily refit the originalhead bolts, with suitable spacers fitted to theirshanks.40 If the cylinder head is to be dismantled for

overhaul, remove the camshafts as describedin Section 10, then refer to Part C of thisChapter.

1998 cc 16-valve engines41 The procedure is similar to that for the1905 cc 16-valve engine described above,except for the following.a) Where necessary remove both camshafts

at the beginning of the procedure asdescribed in Section 10.

b) When removing the inlet manifold,disconnect the ACAV assembly withreference to Chapter 4.

c) Unbolt the oil dipstick tube from thecylinder head.

d) The 1998 cc 16-valve engine has dryliners, and therefore all references to, andprecautions for, wet liners can be ignored.

Preparation for refitting42 The mating faces of the cylinder head andcylinder block/crankcase must be perfectlyclean before refitting the head. Use a hardplastic or wooden scraper to remove all tracesof gasket and carbon; also clean the pistoncrowns. On ‘wet’ liner engines, refer toparagraph 36 before turning the engine. Takeparticular care on these models, as the softaluminium alloy is easily damaged. On allmodels, make sure that the carbon is notallowed to enter the oil and water passages -this is particularly important for the lubricationsystem, as carbon could block the oil supplyto the engine’s components. Using adhesivetape and paper, seal the water, oil and boltholes in the cylinder block/crankcase. Toprevent carbon entering the gap between thepistons and bores, smear a little grease in thegap. After cleaning each piston, use a smallbrush to remove all traces of grease andcarbon from the gap, then wipe away theremainder with a clean rag. Clean all thepistons in the same way.43 Check the mating surfaces of the cylinderblock/crankcase and the cylinder head fornicks, deep scratches and other damage. Ifslight, they may be removed carefully with afile, but if excessive, machining may be theonly alternative to renewal. If warpage of thecylinder head gasket surface is suspected,use a straight-edge to check it for distortion.Refer to Part C of this Chapter if necessary.44 On ‘wet’ liner engines, check the cylinderliner protrusion as described in Part C of thisChapter.

Cylinder head gasket and head boltinformation - 1580 cc, 1761 cc and1905 cc models45 On these models (aluminium cylinderblock, wet-liner type engine) when purchasinga new cylinder head gasket, it is essential thata gasket of the correct thickness is obtained.There are two different thicknesses available,the standard (1.2 mm) gasket which is fitted atthe factory, and a slightly thicker (1.4 mm)gasket, for use once the head gasket face hasbeen machined. The two gaskets can be

12.21 Cylinder liners clamped in positionusing suitable bolts and large flat washers

identified as follows, by the holes in the tab onthe left-hand end of the gasket.46 With the gasket fitted the correct way upon the cylinder block, there will be a either asingle hole, or series of holes, punched in thetab on the left-hand end of the gasket. Thestandard (1.2 mm) gasket has only one holepunched in it; the slightly thicker (1.4 mm)gasket has either two or three holes punchedin it, depending on its manufacturer. Identifythe gasket type, and ensure that the newgasket obtained is of the correct thickness. Ifthere is any doubt as to which gasket is fitted,take the old gasket along to your Peugeotdealer, and have the dealer confirm the gaskettype.47 Check the condition of the cylinder headbolts, and particularly their threads, wheneverthey are removed. Wash the bolts in a suitablesolvent, and wipe them dry. Check each boltfor any sign of visible wear or damage,renewing them if necessary. Measure thelength of each bolt (without the washer fitted),from the underside of its head to the end ofthe bolt. If all bolts are less than 176.5 mm,they may be re-used. However, if any one boltis longer than the specified length, all of thebolts should be renewed as a complete set.Considering the stress which the cylinderhead bolts are under, it is hightlyrecommended that they are renewed,regardless of their apparent condition.

Cylinder head gasket and head boltinformation - 1998 cc 8-valve and 16-valve models48 On 1998 cc models (cast-iron cylinderblock without separate liners) there is only onethickness of head gasket available. The holesdescribed above are still punched into theleft-hand end of the gasket, but are of littleimportance, as they only identify the gasketmanufacturer.49 Check the condition of the cylinder headbolts, and particularly their threads, wheneverthey are removed. Wash the bolts in a suitablesolvent, and wipe them dry. Check each boltfor any sign of visible wear or damage,renewing them if necessary. Measure thelength of each bolt (without the washer fitted),from the underside of its head to the end ofthe bolt. If all bolts are less than 122.0 mm,they may be re-used. However, if any one boltis longer than the specified length, all of thebolts should be renewed as a complete set.Considering the stress which the cylinderhead bolts are under, it is hightlyrecommended that they are renewed,regardless of their apparent condition.

Refitting50 Wipe clean the mating surfaces of thecylinder head and cylinder block/crankcase.Check that the two locating dowels are inposition at each end of the cylinderblock/crankcase surface. Where applicable,remove the cylinder liner clamps.51 Position a new gasket on the cylinder

block/crankcase surface, ensuring that itsidentification holes and tongue are at the left-hand end of the gasket.

8-valve engines52 Where removed refit the camshaft(Section 10), then check that the crankshaftpulley and camshaft sprocket are still lockedin position with their respective pins. With theaid of an assistant, carefully refit the cylinderhead assembly to the block, aligning it withthe locating dowels.53 Apply a smear of grease to the threads,and to the underside of the heads, of thecylinder head bolts. Peugeot recommendMolykote G.RAPID PLUS grease (availablefrom your Peugeot dealer); in the absence ofthe specified grease, any good-quality high-melting-point grease may be used.54 Carefully enter each bolt and washer intoits relevant hole (do not drop it in) and screw itin finger-tight, not forgetting to fit the spacerto the front left-hand bolt.55 Working progressively and in thesequence shown, tighten the cylinder headbolts to their stage 1 torque setting, using atorque wrench and suitable socket (seeillustration).56 On 1508 cc, 1761 cc and 1905 ccengines, working bolt by bolt and in thespecified sequence, fully slacken the boltthen tighten it to its stage 2 torque settingfollowed by its stage 3 angle. It isrecommended that an angle-measuringgauge is used during the stage 3 tightening, toensure accuracy. If a gauge is not available,use white paint to make alignment marksbetween the bolt head and cylinder head priorto tightening; the marks can then be used tocheck that the bolt has rotated sufficiently.57 On 1998 cc engines, working in thecorrect sequence tighten all of the bolts to the stage 2 torque. With all the bolts at thestage 2 torque, angle-tighten the bolts to thestage 3 angle in the correct sequence usingthe gauge described in the previousparagraph.58 Once the cylinder head bolts are correctlytightened, fill the four oil reservoir holes in thecylinder head (below the camshaft) with freshengine oil.59 Reconnect the wiring connector to theignition HT coil. Otherwise, if the head was

stripped for overhaul, refit the HT coil ordistributor (as applicable), as described inChapter 5.60 Refit and tension the timing belt withreference to Section 8.61 Refit the right-hand engine mounting andtighten the bolts to the specified torque. Thejack can then be removed from under theengine.62 The remaining procedure is a reversal ofremoval noting the following points.a) Ensure that all wiring is correctly routed,

and that all connectors are securelyreconnected to the correct components.

b) Ensure that the coolant hoses arecorrectly reconnected, and that theirretaining clips are securely tightened.

c) Ensure that all vacuum/breather hoses arecorrectly reconnected.

d) Refit the cylinder head cover as describedin Section 4.

e) Reconnect the exhaust system to themanifold, refit the air cleaner housing andducts, and adjust the accelerator cable,as described in Chapter 4. If themanifolds were removed, refit these asdescribed in Chapter 4.

f) On completion, refill the cooling systemas described in Chapter 1, and reconnectthe battery.

1905 cc 16-valve engines63 Where removed refit the camshafts(Section 10), then check that the crankshaftpulley and camshaft sprockets are still lockedin position with their respective pins. With theaid of an assistant, carefully refit the cylinderhead assembly to the block, aligning it withthe locating dowels.64 Apply a smear of grease to the threads,and to the underside of the heads, of thecylinder head bolts. Peugeot recommend theuse of Molykote G.RAPID PLUS grease(available from your Peugeot dealer); in theabsence of the specified grease, any good-quality high-melting-point grease may beused.65 Carefully enter each bolt and washer intoits relevant hole (do not drop it in) and screw itin finger-tight, not forgetting to fit the spacerto the front left-hand bolt.66 Working progressively and in thesequence shown, tighten the cylinder headbolts to their stage 1 torque setting, using atorque wrench and suitable socket.67 Working bolt by bolt and in the specifiedsequence, fully slacken the bolt then tighten itto its stage 2 torque setting followed by itsstage 3 angle. It is recommended that anangle-measuring gauge is used during thestage 3 tightening, to ensure accuracy. If agauge is not available, use white paint tomake alignment marks between the bolt headand cylinder head prior to tightening; themarks can then be used to check that the bolthas rotated sufficiently.68 Refit and tension the timing belt withreference to Section 8.

1998 cc 16-valve models71 The procedure is similar to that for the1905 cc 16-valve engine described above, butrefer also to paragraph 40.

13 Sump - removal and refitting 3Removal1 Disconnect the battery negative lead.2 Drain the engine oil, then clean and refit theengine oil drain plug, tightening it securely. Ifthe engine is nearing its service interval whenthe oil and filter are due for renewal, it isrecommended that the filter is also removed,and a new one fitted. After reassembly, theengine can then be refilled with fresh oil. Referto Chapter 1 for further information.3 Apply the handbrake, jack up the front ofthe vehicle and support it on axle stands (see“Jacking and Vehicle Support”).4 On models with air conditioning, where thecompressor is mounted onto the side of thesump, remove the drivebelt as described inChapter 1. Unbolt the compressor, and positionit clear of the sump. Support the weight of thecompressor by tying it to the vehicle, to preventany excess strain being placed on thecompressor lines. Do not disconnect therefrigerant lines from the compressor (refer tothe warnings given in Chapter 3).5 Where necessary, disconnect the wiringconnector from the oil temperature senderunit, which is screwed into the sump.6 Progressively slacken and remove all thesump retaining bolts. Since the sump boltsvary in length, remove each bolt in turn, andstore it in its correct fitted order by pushing itthrough a clearly-marked cardboard template.

This will avoid the possibility of installing thebolts in the wrong locations on refitting.7 Break the joint by striking the sump with thepalm of your hand. Lower the sump, andwithdraw it from underneath the vehicle.Remove the gasket (where fitted), and discardit; a new one must be used on refitting.8 While the sump is removed, take theopportunity to check the oil pump pick-up/strainer for signs of clogging or splitting. Ifnecessary, remove the pump as described inSection 14, and clean or renew the strainer.9 On some models fitted with the 1905 cc 16-valve engine, a large spacer plate is fittedbetween the sump and the base of thecylinder block/crankcase. If this plate is fitted,undo the two retaining screws fromdiagonally-opposite corners of the plate.Remove the plate from the base of the engine,noting which way round it is fitted.

Refitting10 Clean all traces of sealant/gasket from themating surfaces of the cylinderblock/crankcase and sump, then use a cleanrag to wipe out the sump and the engine’sinterior.11 Where a spacer plate is fitted, remove alltraces of sealant/gasket from the spacerplate, then apply a thin coating of suitablesealant to the plate upper mating surface (seeillustrations). Offer up the plate to the base ofthe cylinder block/crankcase, and securelytighten its retaining screws.12 On models where the sump was fittedwithout a gasket (cast-aluminium sump),ensure that the sump mating surfaces areclean and dry, then apply a thin coating ofsuitable silicone sealant to the sump matingsurface.13 On models where the sump was fittedwith a gasket (pressed-steel sump), ensurethat all traces of the old gasket have beenremoved, and that the sump mating surfacesare clean and dry. Position the new gasket onthe top of the sump, using a dab of grease tohold it in position.14 Offer up the sump to the cylinderblock/crankcase. Refit its retaining bolts,ensuring that each is screwed into its originallocation. Tighten the bolts evenly andprogressively to the specified torque setting.

15 Where necessary, align the airconditioning compressor with its mountingson the sump, and insert the retaining bolts.Securely tighten the compressor retainingbolts, then refit the drivebelt as described inChapter 1.16 Reconnect the wiring connector to the oiltemperature sensor (where fitted).17 Lower the vehicle to the ground, then refillthe engine with oil as described in Chapter 1.

14 Oil pump - removal,inspection and refitting 3

Removal1 Remove the sump (see Section 13).2 Where necessary, undo the two retainingscrews, and slide the sprocket cover off thefront of the oil pump.3 Slacken and remove the three boltssecuring the oil pump to the base of thecylinder block/crankcase. Disengage thepump sprocket from the chain, and removethe oil pump (see illustration). Wherenecessary, also remove the spacer platewhich is fitted behind the oil pump.

Inspection4 Examine the oil pump sprocket for signs ofdamage and wear, such as chipped ormissing teeth. If the sprocket is worn, thepump assembly must be renewed, since thesprocket is not available separately. It is alsorecommended that the chain and drive

sprocket, fitted to the crankshaft, be renewedat the same time. To renew the chain anddrive sprocket, first remove the crankshafttiming belt sprocket as described in Section 8.Unbolt the oil seal carrier from the cylinderblock. The sprocket and chain can then beslid off the end of the crankshaft. Refer to PartC for further information.5 Slacken and remove the bolts (along withthe baffle plate, where fitted) securing thestrainer cover to the pump body. Lift off thestrainer cover, and take off the relief valvepiston and spring, noting which way roundthey are fitted (see illustrations).6 Examine the pump rotors and body forsigns of wear ridges or scoring. If worn, thecomplete pump assembly must be renewed.7 Examine the relief valve piston for signs ofwear or damage, and renew if necessary. Thecondition of the relief valve spring can only bemeasured by comparing it with a new one; ifthere is any doubt about its condition, itshould also be renewed. Both the piston andspring are available individually.8 Thoroughly clean the oil pump strainer witha suitable solvent, and check it for signs ofclogging or splitting. If the strainer isdamaged, the strainer and cover assemblymust be renewed.9 Locate the relief valve spring and piston inthe strainer cover. Refit the cover to the pumpbody, aligning the relief valve piston with itsbore in the pump. Refit the baffle plate (wherefitted) and the cover retaining bolts, andtighten them securely.

Refitting10 Offer up the spacer plate (where fitted),then locate the pump sprocket with its drivechain. Seat the pump on the base of thecylinder block/crankcase. Refit the pumpretaining bolts, and tighten them to thespecified torque setting.11 Where necessary, slide the sprocketcover into position on the pump. Refit itsretaining bolts, tightening them securely.12 Refit the sump as described in Section 13.

15 Oil cooler -removal and refitting 2

Note: The oil cooler is not fitted to all models.

Removal1 Firmly apply the handbrake, then jack upthe front of the vehicle and support it on axlestands (see “Jacking and Vehicle Support”).2 Drain the cooling system as described inChapter 1. Alternatively, clamp the oil coolercoolant hoses directly above the cooler, andbe prepared for some coolant loss as thehoses are disconnected.3 Position a suitable container beneath the oilfilter. Unscrew the filter using an oil filterremoval tool if necessary, and drain the oilinto the container. If the oil filter is damaged ordistorted during removal, it must be renewed.Given the low cost of a new oil filter relative tothe cost of repairing the damage which couldresult if a re-used filter springs a leak, it isprobably a good idea to renew the filter in anycase.4 Release the hose clips, and disconnect thecoolant hoses from the oil cooler.5 Unscrew the oil cooler/oil filter mountingbolt from the cylinder block, and withdraw thecooler. Note the locating notch in the coolerflange, which fits over the lug on the cylinderblock (see illustration). Discard the oil coolersealing ring; a new one must be used onrefitting.

Refitting6 Fit a new sealing ring to the recess in therear of the cooler, then offer the cooler to thecylinder block.7 Ensure that the locating notch in the coolerflange is correctly engaged with the lug on thecylinder block, then refit the mounting boltand tighten it securely.8 Fit the oil filter, then lower the vehicle to theground. Top-up the engine oil (refer to“Weekly Checks”).9 Refill or top-up the cooling system (asapplicable) -see Chapter 1. Start the engine,and check the oil cooler for signs of leakage.

16 Crankshaft oil seals - renewal 4Right-hand oil seal1 Remove the crankshaft sprocket andflanged spacer as described in Section 8.Secure the timing belt clear of the workingarea, so that it cannot be contaminated withoil. Make a note of the correct fitted depth ofthe seal in its housing.2 Punch or drill two small holes opposite eachother in the seal. Screw a self-tapping screwinto each, and pull on the screws with pliers toextract the seal (see illustration). The seal canalso be levered out.

17 Flywheel/driveplate -removal, inspection andrefitting

4Removal

Flywheel - models with manual transmission1 Remove the transmission as described inChapter 7A, then remove the clutch assemblyas described in Chapter 6.2 Prevent the flywheel from turning by lockingthe ring gear teeth with a similar arrangementto that shown in illustration 5.3 (Section 5).Alternatively, bolt a strap between theflywheel and the cylinder block/crankcase. Donot attempt to lock the flywheel in positionusing the crankshaft pulley locking pindescribed in Section 3.3 Slacken and remove the flywheel retainingbolts, and remove the flywheel from the endof the crankshaft. Be careful not to drop it; it isheavy. If the flywheel locating dowel is a loosefit in the crankshaft end, remove it and store itwith the flywheel for safe-keeping. Discard the

flywheel bolts; new ones must be used onrefitting.

Driveplate - models with automatic transmission4 Remove the transmission as described inChapter 7B. Lock the driveplate as describedin paragraph 2. Mark the relationship betweenthe torque converter plate and the driveplate,and slacken all the driveplate retaining bolts.5 Remove the retaining bolts, along with thetorque converter plate and the two shims (onefitted on each side of the torque converterplate). Note that the shims are of differentthickness, the thicker one being on theoutside of the torque converter plate. Discardthe driveplate retaining bolts; new ones mustbe used on refitting.6 Remove the driveplate from the end of thecrankshaft. If the locating dowel is a loose fitin the crankshaft end, remove it and store itwith the driveplate for safe-keeping.

Inspection7 On models with manual transmission,examine the flywheel for scoring of the clutchface, and for wear or chipping of the ring gearteeth. If the clutch face is scored, the flywheelmay be surface-ground, but renewal ispreferable. Seek the advice of a Peugeotdealer or engine reconditioning specialist tosee if machining is possible. If the ring gear isworn or damaged, the flywheel must berenewed, as it is not possible to renew thering gear separately.8 On models with automatic transmission,check the torque converter driveplatecarefully for signs of distortion. Look for anyhairline cracks around the bolt holes orradiating outwards from the centre, andinspect the ring gear teeth for signs of wear orchipping. If any sign of wear or damage isfound, the driveplate must be renewed.

Refitting

Flywheel - models with manual transmission9 Clean the mating surfaces of the flywheeland crankshaft. Remove any lockingcompound from the threads of the crankshaftholes, using the correct-size tap, if available.

10 If the new flywheel retaining bolts are notsupplied with their threads already pre-coated, apply a suitable thread-lockingcompound to the threads of each bolt (seeillustration).11 Ensure that the locating dowel is inposition. Offer up the flywheel, locating it onthe dowel, and fit the new retaining bolts.12 Lock the flywheel using the methodemployed on dismantling, and tighten theretaining bolts to the specified torque (seeillustration).13 Refit the clutch as described in Chapter 6.Remove the flywheel locking tool, and refit thetransmission as described in Chapter 7A.

1 General information

Included in this Part of Chapter 2 are detailsof removing the engine/transmission from thecar and general overhaul procedures for thecylinder head, cylinder block/crankcase andall other engine internal components.

The information given ranges from adviceconcerning preparation for an overhaul andthe purchase of replacement parts, to detailedstep-by-step procedures covering removal,inspection, renovation and refitting of engineinternal components.

After Section 6, all instructions are basedon the assumption that the engine has beenremoved from the car. For informationconcerning in-car engine repair, as well as theremoval and refitting of those externalcomponents necessary for full overhaul, referto Part A or B of this Chapter (as applicable)and to Section 6. Ignore any preliminarydismantling operations described in Part A orB that are no longer relevant once the enginehas been removed from the car.

Apart from torque wrench settings, whichare given at the beginning of Part A or B (asapplicable), all specifications relating toengine overhaul are at the beginning of thisPart of Chapter 2.

2 Engine overhaul - general information

1 It is not always easy to determine when, orif, an engine should be completelyoverhauled, as a number of factors must beconsidered.2 High mileage is not necessarily anindication that an overhaul is needed, whilelow mileage does not preclude the need for anoverhaul. Frequency of servicing is probablythe most important consideration. An enginewhich has had regular and frequent oil andfilter changes, as well as other requiredmaintenance, should give many thousands ofmiles of reliable service. Conversely, aneglected engine may require an overhaulvery early in its life.3 Excessive oil consumption is an indicationthat piston rings, valve seals and/or valveguides are in need of attention. Make surethat oil leaks are not responsible beforedeciding that the rings and/or guides areworn. Perform a compression test, asdescribed in Part A of this Chapter, todetermine the likely cause of the problem.4 Check the oil pressure with a gauge fitted inplace of the oil pressure switch, and compareit with that specified. If it is extremely low, themain and big-end bearings, and/or the oilpump, are probably worn out.5 Loss of power, rough running, knocking ormetallic engine noises, excessive valve gear

noise, and high fuel consumption may alsopoint to the need for an overhaul, especially ifthey are all present at the same time. If acomplete service does not remedy thesituation, major mechanical work is the onlysolution.6 An engine overhaul involves restoring allinternal parts to the specification of a newengine. During an overhaul, the cylinder liners(where applicable), the pistons and the pistonrings are renewed. New main and big-endbearings are generally fitted; if necessary, thecrankshaft may be renewed, to restore thejournals. The valves are also serviced as well,since they are usually in less-than-perfectcondition at this point. While the engine isbeing overhauled, other components, such asthe distributor, starter and alternator, can beoverhauled as well. The end result should bean as-new engine that will give many trouble-free miles.

Note: Critical cooling system componentssuch as the hoses, thermostat and waterpump should be renewed when an engine isoverhauled. The radiator should be checkedcarefully, to ensure that it is not clogged orleaking. Also, it is a good idea to renew the oilpump whenever the engine is overhauled.

7 Before beginning the engine overhaul, readthrough the entire procedure, to familiariseyourself with the scope and requirements ofthe job. Overhauling an engine is not difficult ifyou follow all of the instructions carefully,have the necessary tools and equipment, andpay close attention to all specifications. It can,however, be time-consuming. Plan on the carbeing off the road for a minimum of twoweeks, especially if parts must be taken to anengineering works for repair or reconditioning.Check on the availability of parts and makesure that any necessary special tools andequipment are obtained in advance. Mostwork can be done with typical hand tools,although a number of precision measuringtools are required for inspecting parts todetermine if they must be renewed. Often theengineering works will handle the inspectionof parts and offer advice concerning recondi-tioning and renewal.

Note: Always wait until the engine has beencompletely dismantled, and until allcomponents (especially the cylinderblock/crankcase and the crankshaft) havebeen inspected, before deciding what serviceand repair operations must be performed byan engineering works. The condition of thesecomponents will be the major factor toconsider when determining whether tooverhaul the original engine, or to buy areconditioned unit. Do not, therefore,purchase parts or have overhaul work done onother components until they have beenthoroughly inspected. As a general rule, timeis the primary cost of an overhaul, so it doesnot pay to fit worn or sub-standard parts.

8 As a final note, to ensure maximum life andminimum trouble from a reconditioned engine,everything must be assembled with care, in aspotlessly-clean environment.

3 Engine/transmissionremoval - methods andprecautions

1 If you have decided that the engine must beremoved for overhaul or major repair work,several preliminary steps should be taken.2 Locating a suitable place to work isextremely important. Adequate work space,along with storage space for the car, will beneeded. If a workshop or garage is notavailable, at the very least, a flat, level, cleanwork surface is required.3 Cleaning the engine compartment andengine/transmission before beginning theremoval procedure will help keep tools cleanand organised.4 An engine hoist or A-frame will also benecessary. Ensure the equipment is rated inexcess of the combined weight of the engineand transmission. Safety is of primaryimportance, considering the potential hazardsin lifting the engine/transmission out of the car.5 If this is the first time you have removed anengine, an assistant should ideally beavailable. Advice and aid from someone moreexperienced would also be helpful. There aremany instances when one person cannotsimultaneously perform all of the operationsrequired when lifting the engine out of the car.6 Plan the operation ahead of time. Beforestarting work, arrange for the hire of or obtainall of the tools and equipment you will need.Some of the equipment necessary to performengine/transmission removal and installationsafely and with relative ease (in addition to anengine hoist) is as follows: a heavy duty trolleyjack, complete sets of spanners and socketsas described in the front of this manual,wooden blocks, and plenty of rags andcleaning solvent for mopping up spilled oil,coolant and fuel. If the hoist must be hired,make sure that you arrange for it in advance,and perform all of the operations possiblewithout it beforehand. This will save youmoney and time.7 Plan for the car to be out of use for quite awhile. An engineering works will be requiredto perform some of the work which the do-it-yourselfer cannot accomplish without specialequipment. These places often have a busyschedule, so it would be a good idea toconsult them before removing the engine, inorder to accurately estimate the amount oftime required to rebuild or repair componentsthat may need work.8 Always be extremely careful when removingand refitting the engine/transmission. Seriousinjury can result from careless actions. Planahead and take your time, and a job of thisnature, although major, can be accomplishedsuccessfully.

2C•4 Engine removal and overhaul

4 Engine and manualtransmission - removal,separation and refitting

4Note: Peugeot recommend that 8-valve XUengines are removed by lowering from theengine compartment, however in practise wefound that on models not fitted with airconditioning, there is ample room to lift theengine upwards. Lowering the engine wouldinvolve raising the front of the vehicle ontoaxle stands approximately 21 inches high andalso removing the engine subframe. Onmodels fitted with air conditioning the enginemay be lowered, or alternatively it can be liftedafter removing the condenser and front panel(the refrigerant must first be evacuated by aqualified engineer if this method is used).

RemovalNote: The engine can be removed from thecar only as a complete unit with thetransmission; the two are then separated foroverhaul.1 Park the vehicle on firm, level ground.Chock the rear wheels, then firmly apply thehandbrake. Jack up the front of the vehicle,and securely support it on axle stands (see“Jacking and Vehicle Support”). Remove bothfront roadwheels.2 Set the bonnet in the upright position, andremove the battery and tray as described inChapter 5A.3 On 8-valve XU engines remove the frontcross panel with reference to Chapter 11 (seenote at the beginning of this Section).4 Remove the complete air cleaner housingand duct assembly, as described in therelevant Part of Chapter 4 (see illustration).5 If the engine is to be dismantled, working asdescribed in Chapter 1, first drain the oil andremove the oil filter. Clean and refit the drainplug, tightening it securely.6 Drain the transmission oil as described inChapter 7A. Refit the drain and filler plugs,and tighten them to their specified torquesettings.7 Remove the alternator as described inChapter 5A.8 Where applicable, remove the powersteering pump as described in Chapter 10.

9 On models with air conditioning, unbolt thecompressor, and position it clear of theengine. Support the weight of the compressorby tying it to the vehicle body, to prevent anyexcess strain being placed on the compressorlines whilst the engine is removed. Do notdisconnect the refrigerant lines from thecompressor (refer to the warnings given inChapter 3).10 Drain the cooling system as described inChapter 1. Where necessary on 8-valve XUengines, remove the radiator (see Chapter 3).11 On carburettor models, carry out thefollowing operations, using the informationgiven in Chapter 4A:a) Disconnect the fuel feed hose from the

anti-percolation chamber.b) Disconnect the accelerator and choke

cables from the carburettor.c) Disconnect the braking system servo

vacuum hose from the inlet manifold.d) Remove the exhaust system front pipe.

12 On fuel injection models, carry out thefollowing operations, using the informationgiven in Chapter 4B or 4C (as applicable):a) Depressurise the fuel system, and

disconnect the fuel feed and return hoses.b) Disconnect the accelerator cable.c) Disconnect the fuel system wiring

connectors.d) Disconnect the purge valve and/or

braking system servo vacuum hoses fromthe inlet manifold (as applicable).

e) Remove the exhaust system front pipe.13 Referring to Chapter 3, release theretaining clip and disconnect the heater matrixhoses from their connection on the enginecompartment bulkhead.14 Working as described in Chapter 6,disconnect the clutch cable from thetransmission, and position it clear of theworking area (see illustration).15 Trace the wiring harness back from theengine to the wiring connector(s) in the enginecompartment. Release the locking ring(s) bytwisting them anti-clockwise and disconnectthe connectors. Also trace the harness lead(s)back to the relay box, situated beside thebattery. Unclip the wiring connector platefrom the front of the relay box cover thenundo the retaining nut and remove the cover.Lift up the engine harness lead cover then

undo the nut(s) and release the lead(s) fromthe relay box. Check that all the relevantconnectors have been disconnected, and thatthe wiring is released from any relevant clipsor ties, so that it is free to be removed with theengine/transmission.16 From underneath the vehicle, slacken andremove the nuts and bolts securing the rearmounting link to the mounting assembly andsubframe, and remove the link.17 Remove both driveshafts as described inChapter 8.18 Carry out the following operations, usingthe information given in Chapter 7A:a) Disconnect the gearchange selector

rod/link rods (as applicable) from thetransmission.

b) Disconnect the speedometer cable fromthe speedometer drive.

c) Disconnect the wiring connector(s) fromthe reversing light switch andspeedometer drive (as applicable).

19 Manoeuvre the engine hoist into position,and attach it to the lifting brackets bolted ontothe cylinder head. Raise the hoist until it issupporting the weight of the engine.20 Remove the right-hand engine mountingwith reference to Chapter 2A.

Note: On certain models, if the right-handengine mounting hydro-elastic unit is to berenewed because of wear/perishing, a specialtool is needed to unscrew it from the wingpanel, and for refitting and tightening to thespecified torque (see illustration).

21 Slacken and remove the centre nut andwasher from the engine/transmission left-hand mounting. Undo the two nuts andwashers securing the mounting to its bracketand remove the mounting from the enginecompartment and recover the spacer (wherefitted). To improve clearance, (where possible)undo the two retaining bolts and remove thebracket from the body.22 Make a final check that any componentswhich would prevent the removal of theengine/transmission from the car have beenremoved or disconnected. Ensure thatcomponents such as the gearchange selectorrod are secured so that they cannot bedamaged on removal.

23 Lift the engine/transmission out of the car,ensuring that nothing is trapped or damaged.Enlist the help of an assistant during thisprocedure, as it will be necessary to tilt theassembly slightly to clear the body panels. Onmodels equipped with anti-lock brakes, greatcare must be taken to ensure that the anti-lock braking system unit is not damagedduring the removal procedure.24 Once the engine is high enough, lift it outover the front of the body, and lower the unitto the ground.

Separation25 With the engine/transmission assemblyremoved, support the assembly on suitableblocks of wood, on a workbench (or alter-natively, on a clean area of the workshopfloor).26 Undo the retaining bolts, and remove theflywheel lower cover plate (where fitted) fromthe transmission.27 On models with a “pull-type” clutchrelease mechanism (see Chapter 6 for furtherinformation), tap out the retaining pin orunscrew the retaining bolt (as applicable), andremove the clutch release lever from the topof the release fork shaft. This is necessary toallow the fork shaft to rotate freely, so that itdisengages from the release bearing as thetransmission is pulled away from the engine.Make an alignment mark across the centre ofthe clutch release fork shaft, using a scriber,paint or similar, and mark its relative positionon the transmission housing (see Chapter 7Afor further information).28 Slacken and remove the retaining bolts,and remove the starter motor from thetransmission.29 Ensure that both engine and transmissionare adequately supported, then slacken andremove the remaining bolts securing thetransmission housing to the engine. Note thecorrect fitted positions of each bolt (and therelevant brackets) as they are removed, to useas a reference on refitting.30 Carefully withdraw the transmission fromthe engine, ensuring that the weight of thetransmission is not allowed to hang on theinput shaft while it is engaged with the clutchfriction disc.31 If they are loose, remove the locatingdowels from the engine or transmission, andkeep them in a safe place.32 On models with a “pull-type” clutch, makea second alignment mark on the transmissionhousing, marking the relative position of therelease fork mark after removal. This shouldindicate the angle at which the release fork ispositioned. The mark can then be used toposition the release fork prior to installation, toensure that the fork correctly engages withthe clutch release bearing as the transmissionis installed.

Refitting33 If the engine and transmission have beenseparated, perform the operations described

below in paragraphs 34 to 42. If not, proceedas described from paragraph 43 onwards.34 Apply a smear of high-melting-pointgrease (Peugeot recommend the use ofMolykote BR2 plus - available from yourPeugeot dealer) to the splines of thetransmission input shaft. Do not apply toomuch, otherwise there is a possibility of thegrease contaminating the clutch friction plate.35 Ensure that the locating dowels arecorrectly positioned in the engine ortransmission.36 On models with a “pull-type” clutch,before refitting, position the clutch releasebearing so that its arrow mark is pointingupwards (bearing fork slots facing towards thefront of the engine), and align the release forkshaft mark with the second mark made on thetransmission housing (release fork positionedat approximately 60° to clutch housing face).This will ensure that the release fork andbearing will engage correctly as thetransmission is refitted to the engine.37 Carefully offer the transmission to theengine, until the locating dowels are engaged.Ensure that the weight of the transmission isnot allowed to hang on the input shaft as it isengaged with the clutch friction disc.38 On models with a “pull-type” clutch, withthe transmission fully engaged with theengine, check that the release fork andbearing are correctly engaged. If the releasefork and bearing are correctly engaged, themark on the release fork should be alignedwith the original mark made on thetransmission housing (see Chapter 7A forfurther information).39 Refit the transmission housing-to-enginebolts, ensuring that all the necessary bracketsare correctly positioned, and tighten them tothe specified torque setting.40 Refit the starter motor, and securelytighten its retaining bolts.41 On models with a “pull-type” clutchrelease mechanism, refit the clutch releaselever to the top of the release fork shaft,securing it in position with its retaining pin orbolt (as applicable).42 Where necessary, refit the lower flywheelcover plate to the transmission, and securelytighten its retaining bolts.43 Reconnect the hoist and lifting tackle tothe engine lifting brackets. With the aid of anassistant, lift the assembly over the enginecompartment.44 The assembly should be tilted asnecessary to clear the surroundingcomponents, as during removal; lower theassembly into position in the enginecompartment, manipulating the hoist andlifting tackle as necessary.45 With the engine/transmission in position,refit the right-hand engine/transmissionmounting bracket, tightening its retaining nutsand bolts (as applicable) by hand only at thisstage.46 Working on the left-hand mounting, refitthe mounting bracket (where removed) to the

body and tighten its retaining bolts to thespecified torque. Refit the mounting rubberand refit the mounting retaining nuts andwashers and the centre nut and washer,tightening them lightly only.47 From underneath the vehicle, refit the rearmounting link and install both its bolts.48 Rock the engine to settle it on itsmountings then go around and tighten all themounting nuts and bolts to their specifiedtorque settings. Where necessary, once theright-hand mounting bracket nuts have beentightened, refit the rubber damper and curvedretaining plate, tightening its retaining bolts tothe specified torque. The hoist can then bedetached from the engine and removed.49 The remainder of the refitting procedure isa direct reversal of the removal sequence,noting the following points:a) Ensure that the wiring loom is correctly

routed and retained by all the relevantretaining clips; all connectors should becorrectly and securely reconnected.

b) Prior to refitting the driveshafts to thetransmission, renew the driveshaft oilseals as described in Chapter 7A.

c) Ensure that all coolant hoses are correctlyreconnected, and securely retained bytheir retaining clips.

d) Adjust the clutch cable as described inChapter 6.

e) Adjust the choke cable and/or acceleratorcable (as applicable) as described in therelevant Part of Chapter 4.

f) Refill the engine and transmission withcorrect quantity and type of lubricant, asdescribed in Chapter 7A.

g) Refill the cooling system as described inChapter 1.

5 Engine and automatictransmission - removal,separation and refitting

4RemovalNote: The engine can be removed from thecar only as a complete unit with thetransmission; the two are then separated foroverhaul.1 Carry out the relevant operations describedin paragraphs 1 to 24 of Section 4, noting thatthe transmission oil draining procedure isgiven in Chapter 1. Before lifting the enginefrom the engine compartment, carry out thefollowing operations, using the informationgiven in Chapter 7B:a) Remove the transmission dipstick tube.b) Disconnect the wiring from the starter

inhibitor/reversing light switch and thespeedometer drive housing. Release theearth strap(s) from the top of thetransmission housing.

c) Disconnect the selector cable.d) Release the power steering pipe from the

transmission.e) Disconnect the speedometer cable.

2C•6 Engine removal and overhaul

Separation2 With the engine/transmission assemblyremoved, support the assembly on suitableblocks of wood, on a workbench (or failingthat, on a clean area of the workshop floor).3 Detach the kickdown cable from the throttlecam. Work back along the cable, freeing itfrom any retaining clips, and noting its correctrouting.4 Undo the retaining bolts and remove thedriveplate lower cover plate from thetransmission, to gain access to the torqueconverter retaining bolts. Slacken and removethe visible bolt. Rotate the crankshaft using asocket and extension bar on the pulley bolt,and undo the remaining bolts securing thetorque converter to the driveplate as theybecome accessible. There are three bolts intotal.5 Slacken and remove the retaining bolts,and remove the starter motor from thetransmission.6 To ensure that the torque converter doesnot fall out as the transmission is removed,secure it in position using a length of metalstrip bolted to one of the starter motor boltholes.7 Ensure that both the engine andtransmission are adequately supported, thenslacken and remove the remaining boltssecuring the transmission housing to theengine. Note the correct fitted positions ofeach bolt (and any relevant brackets) as theyare removed, to use as a reference onrefitting.8 Carefully withdraw the transmission fromthe engine. If the locating dowels are a loosefit in the engine/transmission, remove themand keep them in a safe place.

Refitting9 If the engine and transmission have beenseparated, perform the operations describedbelow in paragraphs 10 to 16. If not, proceedas described from paragraph 17 onwards.10 Ensure that the bush fitted to the centre ofthe crankshaft is in good condition. Apply alittle Molykote G1 grease (available from yourPeugeot dealer) to the torque convertercentring pin. Do not apply too much,otherwise there is a possibility of the greasecontaminating the torque converter.11 Ensure that the locating dowels arecorrectly positioned in the engine ortransmission.12 Carefully offer the transmission to theengine, until the locating dowels are engaged.13 Refit the transmission housing-to-enginebolts, ensuring that all the necessary bracketsare correctly positioned, and tighten them tothe specified torque setting.14 Remove the torque converter retainingstrap installed prior to removal. Align thetorque converter threaded holes with theretaining plate, and refit the three retainingbolts.15 Tighten the torque converter retaining

bolts to the specified torque setting, then refitthe driveplate lower cover.16 Refit the starter motor, and securelytighten its retaining bolts.17 Refit the engine to the vehicle withreference to Section 4.18 The remainder of the refitting procedure isa reversal of the removal sequence, noting thefollowing points:a) Ensure that the wiring loom is correctly

routed, and retained by all the relevantretaining clips; all connectors should becorrectly and securely reconnected.

b) Prior to refitting the driveshafts to thetransmission, renew the driveshaft oilseals as described in Chapter 7B.

c) Ensure that all coolant hoses are correctlyreconnected, and securely retained bytheir retaining clips.

e) Adjust the accelerator cable as describedin Chapter 4.

f) Refill the engine and transmission withcorrect quantity and type of lubricant, asdescribed in Chapter 1.

g) Refill the cooling system as described inChapter 1.

6 Engine overhaul - dismantling sequence

1 It is much easier to dismantle and work onthe engine if it is mounted on a portableengine stand. These stands can often be hiredfrom a tool hire shop. Before the engine ismounted on a stand, the flywheel/driveplateshould be removed, so that the stand boltscan be tightened into the end of the cylinderblock/crankcase.2 If a stand is not available, it is possible todismantle the engine with it blocked up on asturdy workbench, or on the floor. Be extra-careful not to tip or drop the engine whenworking without a stand.3 If you are going to obtain a reconditionedengine, all the external components must beremoved first, to be transferred to thereplacement engine (just as they will if you aredoing a complete engine overhaul yourself).These components include the following:a) Alternator mounting brackets.b) Power steering pump and air conditioning

compressor brackets (where fitted).c) Thermostat and housing, and coolant

outlet chamber/elbow (Chapter 3).d) Dipstick tube.e) Carburettor/fuel system components

(Chapter 4).f) All electrical switches and sensors.g) Inlet and exhaust manifolds (Chapter 4).h) Oil filter (Chapter 1).i) Fuel pump - carburettor engines only

(Chapter 4).j) Flywheel/driveplate (Part A or B of this

Chapter).

Note: When removing the externalcomponents from the engine, pay closeattention to details that may be helpful orimportant during refitting. Note the fittedposition of gaskets, seals, spacers, pins,washers, bolts, and other small items.4 If you are obtaining a “short” engine (whichconsists of the engine cylinder block/crankcase, crankshaft, pistons andconnecting rods all assembled), then thecylinder head, sump, oil pump, and timing beltwill have to be removed also.5 If you are planning a complete overhaul, theengine can be dismantled, and the internalcomponents removed, in the order givenbelow, referring to Part A or B of this Chapterunless otherwise stated.a) Inlet and exhaust manifolds (Chapter 4).b) Timing belt, sprockets and tensioner(s).c) Cylinder head.d) Flywheel/driveplate.e) Sump.f) Oil pump.g) Piston/connecting rod assemblies

(Section 10).h) Crankshaft (Section 11).

6 Before beginning the dismantling andoverhaul procedures, make sure that you haveall of the correct tools necessary. Refer to“Tools and working facilities” for furtherinformation.

7 Cylinder head - dismantling 3Note: New and reconditioned cylinder headsare available from the manufacturer, and fromengine overhaul specialists. Be aware thatsome specialist tools are required for thedismantling and inspection procedures, andnew components may not be readily available.It may therefore be more practical andeconomical for the home mechanic topurchase a reconditioned head, rather thandismantle, inspect and recondition the originalhead.1 Remove the cylinder head as described inPart A or B of this Chapter (as applicable).2 If not already done, remove the inlet andexhaust manifolds with reference to therelevant Part of Chapter 4.3 Remove the camshaft(s), followers andshims (as applicable) as described in Part A orB of this Chapter.4 Using a valve spring compressor, compresseach valve spring in turn until the split colletscan be removed. Release the compressor,and lift off the spring retainer, spring andspring seat. Using a pair of pliers, carefullyextract the valve stem seal from the top of theguide (see illustrations).5 If, when the valve spring compressor isscrewed down, the spring retainer refuses tofree and expose the split collets, gently tapthe top of the tool, directly over the retainer,with a light hammer. This will free the retainer.

6 Withdraw the valve through the combustionchamber.7 It is essential that each valve is storedtogether with its collets, retainer, spring, andspring seat. The valves should also be kept intheir correct sequence, unless they are sobadly worn that they are to be renewed. Ifthey are going to be kept and used again,place each valve assembly in a labelledpolythene bag or similar small container (seeillustration). Note that No 1 valve is nearest tothe transmission (flywheel/driveplate) end ofthe engine.8 On XU engines extract the gauze oil filterfrom the oil gallery in the cylinder head (seeillustration).

8 Cylinder head and valves -cleaning and inspection 2

1 Thorough cleaning of the cylinder head andvalve components, followed by a detailedinspection, will enable you to decide howmuch valve service work must be carried outduring the engine overhaul. Note: If theengine has been severely overheated, it is bestto assume that the cylinder head is warped -check carefully for signs of this.

Cleaning2 Scrape away all traces of old gasketmaterial from the cylinder head.3 Scrape away the carbon from thecombustion chambers and ports, then washthe cylinder head thoroughly with paraffin or asuitable solvent.

4 Scrape off any heavy carbon deposits thatmay have formed on the valves, then use apower-operated wire brush to removedeposits from the valve heads and stems.

InspectionNote: Be sure to perform all the followinginspection procedures before concluding thatthe services of a machine shop or engineoverhaul specialist are required. Make a list ofall items that require attention.

Cylinder head5 Inspect the head very carefully for cracks,evidence of coolant leakage, and otherdamage. If cracks are found, a new cylinderhead should be obtained.6 Use a straight-edge and feeler blade tocheck that the cylinder head surface is notdistorted (see illustration). If it is, it may bepossible to have it machined, provided that

the cylinder head is not reduced to less thanthe specified height.7 Examine the valve seats in each of thecombustion chambers. If they are severelypitted, cracked, or burned, they will need tobe renewed or re-cut by an engine overhaulspecialist. If they are only slightly pitted, thiscan be removed by grinding-in the valveheads and seats with fine valve-grindingcompound, as described below.8 Check the valve guides for wear byinserting the relevant valve, and checking forside-to-side motion of the valve. A very smallamount of movement is acceptable. If themovement seems excessive, remove thevalve. Measure the valve stem diameter (seebelow), and renew the valve if it is worn. If thevalve stem is not worn, the wear must be inthe valve guide, and the guide must berenewed. The renewal of valve guides is bestcarried out by a Peugeot dealer or engineoverhaul specialist, who will have thenecessary tools available. Where no valvestem diameter is specified, seek the advice ofa Peugeot dealer on the best course of action.9 If renewing the valve guides, the valve seatsshould be re-cut or re-ground only after theguides have been fitted.

Valves10 Examine the head of each valve forpitting, burning, cracks, and general wear.Check the valve stem for scoring and wearridges. Rotate the valve, and check for anyobvious indication that it is bent. Look for pitsor excessive wear on the tip of each valvestem. Renew any valve that shows any suchsigns of wear or damage.11 If the valve appears satisfactory at thisstage, measure the valve stem diameter atseveral points using a micrometer (seeillustration). Any significant difference in thereadings obtained indicates wear of the valvestem. Should any of these conditions beapparent, the valve(s) must be renewed.12 If the valves are in satisfactory condition,they should be ground (lapped) into theirrespective seats, to ensure a smooth, gas-tight seal. If the seat is only lightly pitted, or ifit has been re-cut, fine grinding compoundonly should be used to produce the requiredfinish. Coarse valve-grinding compoundshould not be used, unless a seat is badlyburned or deeply pitted. If this is the case, the

cylinder head and valves should be inspectedby an expert, to decide whether seat re-cutting, or even the renewal of the valve orseat insert (where possible) is required.13 Valve grinding is done as follows. Placethe cylinder head upside-down on a bench.14 Smear a trace of (the appropriate gradeof) valve-grinding compound on the seat face,and press a suction grinding tool onto thevalve head (see illustration). With a semi-rotary action, grind the valve head to its seat,lifting the valve occasionally to redistribute thegrinding compound. A light spring placedunder the valve head will greatly ease thisoperation.15 If coarse grinding compound is beingused, work only until a dull, matt even surfaceis produced on both the valve seat and thevalve, then wipe off the used compound, andrepeat the process with fine compound. Whena smooth unbroken ring of light grey mattfinish is produced on both the valve and seat,the grinding operation is complete. Do notgrind-in the valves any further than absolutelynecessary, or the seat will be prematurelysunk into the cylinder head.16 When all the valves have been ground-in,carefully wash off all traces of grindingcompound using paraffin or a suitable solvent,before reassembling the cylinder head.

Valve components17 Examine the valve springs for signs ofdamage and discoloration. No minimum freelength is specified by Peugeot, so the onlyway of judging valve spring wear is bycomparison with a new component.18 Stand each spring on a flat surface, and

check it for squareness. If any of the springsare damaged, distorted or have lost theirtension, obtain a complete new set of springs.It is normal to renew the valve springs as amatter of course if a major overhaul is beingcarried out.19 Renew the valve stem oil seals regardlessof their apparent condition.

9 Cylinder head - reassembly 31 Lubricate the stems of the valves, andinsert the valves into their original locations(see illustration). If new valves are beingfitted, insert them into the locations to whichthey have been ground.2 Refit the spring seat then, working on thefirst valve, dip the new valve stem seal in freshengine oil. Carefully locate it over the valveand onto the guide. Take care not to damagethe seal as it is passed over the valve stem.Use a suitable socket or metal tube to pressthe seal firmly onto the guide (seeillustration).3 Locate the valve spring on top of its seat,then refit the spring retainer.4 Compress the valve spring, and locate thesplit collets in the recess in the valve stem.Release the compressor, then repeat theprocedure on the remaining valves.

5 With all the valves installed, place thecylinder head flat on the bench and, using ahammer and interposed block of wood, tapthe end of each valve stem to settle thecomponents.6 Refit the camshaft(s), followers and shims(as applicable) as described in Part A or B ofthis Chapter.7 On XU engines refit the gauze oil filter(clean) to the oil gallery in the cylinder head. Ifthe filter is damaged fit a new one.8 The cylinder head can then be refitted asdescribed in Part A or B of this Chapter.

10 Piston/connecting rodassembly - removal 4

1 Remove the cylinder head, sump and oilpump as described in Part A or B of thisChapter (as applicable).2 If there is a pronounced wear ridge at thetop of any bore, it may be necessary toremove it with a scraper or ridge reamer, toavoid piston damage during removal. Such aridge indicates excessive wear of the cylinderbore.3 Using a hammer and centre-punch, paint orsimilar, mark each connecting rod big-endbearing cap with its respective cylindernumber on the flat machined surfaceprovided; if the engine has been dismantledbefore, note carefully any identifying marksmade previously (see illustration). Note thatNo 1 cylinder is at the transmission (flywheel)end of the engine.4 Turn the crankshaft to bring pistons 1 and 4to BDC (bottom dead centre).5 Unscrew the nuts from No 1 piston big-endbearing cap. Take off the cap, and recover thebottom half bearing shell (see illustration). Ifthe bearing shells are to be re-used, tape thecap and the shell together.6 To prevent the possibility of damage to thecrankshaft bearing journals, tape over theconnecting rod stud threads (seeillustration).7 Using a hammer handle, push the piston upthrough the bore, and remove it from the topof the cylinder block. Recover the bearingshell, and tape it to the connecting rod forsafe-keeping.8 Loosely refit the big-end cap to theconnecting rod, and secure with the nuts -this will help to keep the components in theircorrect order.9 Remove No 4 piston assembly in the sameway.10 Turn the crankshaft through 180° to bringpistons 2 and 3 to BDC (bottom dead centre),and remove them in the same way.

11 Crankshaft - removal 41 Remove the crankshaft sprocket and the oilpump as described in Part A or B of thisChapter (as applicable). Also unbolt andremove the timing belt rear cover noting theposition of the special retaining studs (seeillustration).2 Remove the pistons and connecting rods,as described in Section 10. If no work is to bedone on the pistons and connecting rods,there is no need to remove the cylinder head,or to push the pistons out of the cylinderbores. The pistons should just be pushed farenough up the bores that they are positionedclear of the crankshaft journals.3 Check the crankshaft endfloat as describedin Section 14, then proceed as follows.

TU series aluminium block engines 4 Work around the outside of the cylinderblock, and unscrew all the small (6 mm) boltssecuring the main bearing ladder to the baseof the cylinder block. Note the correct fitteddepth of both the front and rear crankshaft oilseals in the cylinder block/main bearingladder.5 Working in a diagonal sequence, evenlyand progressively slacken the ten large (11 mm) main bearing ladder retaining bolts

by a turn at a time. Once all the bolts areloose, remove them from the ladder.6 With all the retaining bolts removed,carefully lift the main bearing ladder castingaway from the base of the cylinder block.Recover the lower main bearing shells, andtape them to their respective locations in thecasting. If the two locating dowels are a loosefit, remove them and store them with thecasting for safe-keeping.7 Lift out the crankshaft, and discard both theoil seals. Remove the oil pump drive chainfrom the end of the crankshaft. Wherenecessary, slide off the drive sprocket, andrecover the Woodruff key.8 Recover the upper main bearing shells, andstore them along with the relevant lowerbearing shell. Also recover the twothrustwashers (one fitted either side of No 2main bearing) from the cylinder block.

12 Cylinder block/crankcase -cleaning and inspection 2

Cleaning1 Remove all external components andelectrical switches/sensors from the block.For complete cleaning, the core plugs shouldideally be removed (see illustration). Drill asmall hole in the plugs, then insert a self-tapping screw into the hole. Pull out the plugsby pulling on the screw with a pair of grips, orby using a slide hammer.2 On aluminium block engines with wet liners,remove the liners, referring to paragraph 18.3 Where applicable, undo the retaining boltand remove the piston oil jet spray tube frominside the cylinder block.4 Scrape all traces of gasket from the cylinderblock/crankcase, and from the main bearing

ladder (where fitted), taking care not todamage the gasket/sealing surfaces.5 Remove all oil gallery plugs (where fitted).The plugs are usually very tight - they mayhave to be drilled out, and the holes re-tapped. Use new plugs when the engine isreassembled.6 If any of the castings are extremely dirty, allshould be steam-cleaned.7 After the castings are returned, clean all oilholes and oil galleries one more time. Flush allinternal passages with warm water until thewater runs clear. Dry thoroughly, and apply alight film of oil to all mating surfaces, toprevent rusting. On cast-iron block engines,also oil the cylinder bores. If you have accessto compressed air, use it to speed up thedrying process, and to blow out all the oilholes and galleries.

8 If the castings are not very dirty, you can doan adequate cleaning job with hot (as hot asyou can stand!), soapy water and a stiff brush.Take plenty of time, and do a thorough job.Regardless of the cleaning method used, besure to clean all oil holes and galleries verythoroughly, and to dry all components well.On cast-iron block engines, protect thecylinder bores as described above, to preventrusting.9 All threaded holes must be clean, to ensureaccurate torque readings during reassembly.To clean the threads, run the correct-size tapinto each of the holes to remove rust,corrosion, thread sealant or sludge, and torestore damaged threads (see illustration). Ifpossible, use compressed air to clear theholes of debris produced by this operation.

10 Apply suitable sealant to the new oilgallery plugs, and insert them into the holes inthe block. Tighten them securely.11 Where applicable, clean the threads of thepiston oil jet retaining bolt, and apply a dropof thread-locking compound to the boltthreads. Refit the piston oil jet spray tube tothe cylinder block, and tighten its retainingbolt to the specified torque setting.12 If the engine is not going to bereassembled right away, cover it with a largeplastic bag to keep it clean; protect all matingsurfaces and the cylinder bores as describedabove, to prevent rusting.

Inspection

Cast-iron cylinder block13 Visually check the castings for cracks andcorrosion. Look for stripped threads in thethreaded holes. If there has been any historyof internal water leakage, it may be worthwhilehaving an engine overhaul specialist checkthe cylinder block/crankcase with specialequipment. If defects are found, have themrepaired if possible, or renew the assembly.14 Check each cylinder bore for scuffing andscoring. Check for a wear ridge at the top of thecylinder, indicating that the bore is badly worn.15 If the necessary measuring equipment isavailable, measure the bore diameter of eachcylinder liner at the top (just under the wearridge), centre, and bottom of the cylinderbore, parallel to the crankshaft axis.16 Next, measure the bore diameter at thesame three locations, at right-angles to thecrankshaft axis. Compare the results with thefigures given in the Specifications. Where nofigures are stated by Peugeot, if there is anydoubt about the condition of the cylinderbores seek the advice of a Peugeot dealer orsuitable engine reconditioning specialist.17 At the time of writing, it was not clearwhether oversize pistons were available for allmodels. Consult your Peugeot dealer for thelatest information on piston availability. Ifoversize pistons are available then it may bepossible to have the cylinder bores reboredand fit the oversize pistons. If it provesoversize pistons are not available, and thebores are worn, renewal of the block seems tobe the only option.

Aluminium cylinder block with wet liners18 Remove the liner clamps (where used),then use a hard wood drift to tap out eachliner from the inside of the cylinder block.When all the liners are released, tip thecylinder block/crankcase on its side andremove each liner from the top of the block.As each liner is removed, stick masking tapeon its left-hand (transmission side) face, andwrite the cylinder number on the tape. No 1cylinder is at the transmission (flywheel/driveplate) end of the engine. Remove the O-ring from the base of each liner, and discard(see illustrations).19 Check each cylinder liner for scuffing andscoring. Check for signs of a wear ridge at thetop of the liner, indicating that the bore isexcessively worn.20 If the necessary measuring equipment isavailable, measure the bore diameter of eachcylinder liner at the top (just under the wearridge), centre, and bottom of the cylinderbore, parallel to the crankshaft axis.21 Next, measure the bore diameter at thesame three locations, at right-angles to thecrankshaft axis. Compare the results with thefigures given in the Specifications.22 Repeat the procedure for the remainingcylinder liners.23 If the liner wear exceeds the permittedtolerances at any point, or if the cylinder linerwalls are badly scored or scuffed, thenrenewal of the relevant liner assembly will benecessary. If there is any doubt about thecondition of the cylinder bores, seek theadvice of a Peugeot dealer or engine recondi-tioning specialist.24 If renewal is necessary, new liners,complete with pistons and piston rings, canbe purchased from a Peugeot dealer. Notethat it is not possible to buy liners individually- they are supplied only as a matchedassembly complete with piston and rings.25 To allow for manufacturing tolerances,pistons and liners are separated into threesize groups. The size group of each piston isindicated by a letter (A, B or C) stamped ontoits crown, and the size group of each liner isindicated by a series of 1 to 3 notches on theupper lip of the liner; a single notch for group A, two notches for group B, and three

notches for group C. Ensure that each pistonand its respective liner are both of the samesize group. It is permissible to have differentsize group piston and liner assemblies fittedto the same engine, but never fit a piston ofone size group to a liner in a different group.26 Prior to installing the liners, thoroughlyclean the liner mating surfaces in the cylinderblock, and use fine abrasive paper to polishaway any burrs or sharp edges which mightdamage the liner O-rings. Clean the liners andwipe dry, then fit a new O-ring to the base ofeach liner. To aid installation, apply a smear ofoil to each O-ring and to the base of the liner.27 If the original liners are being refitted, usethe marks made on removal to ensure thateach is refitted the correct way round, and isinserted into its original position. Insert eachliner into the cylinder block, taking care not todamage the O-ring, and press it home as faras possible by hand. Using a hammer and ablock of wood, tap each liner lightly but fullyonto its locating shoulder. Wipe clean, thenlightly oil, all exposed liner surfaces, toprevent rusting.28 With all four liners correctly installed, usea dial gauge (or a straight-edge and feelerblade) to check that the protrusion of eachliner above the upper surface of the cylinderblock is within the limits given in the Specifi-cations. The maximum difference betweenany two liners must not be exceeded.29 If new liners are being fitted, it ispermissible to interchange them to bring thedifference in protrusion within limits. Keepeach piston with its respective liner.30 If liner protrusion cannot be broughtwithin limits, seek the advice of a Peugeotdealer or engine reconditioning specialistbefore proceeding with the engine rebuild.

13 Piston/connecting rodassembly - inspection 3

1 Before the inspection process can begin,the piston/connecting rod assemblies mustbe cleaned, and the original piston ringsremoved from the pistons.2 Carefully expand the old rings over the topof the pistons. The use of two or three oldfeeler blades will be helpful in preventing therings dropping into empty grooves (seeillustration). Be careful not to scratch thepiston with the ends of the ring. The rings arebrittle, and will snap if they are spread too far.They’re also very sharp - protect your handsand fingers. Note that the third ringincorporates an expander. Always remove therings from the top of the piston. Keep each setof rings with its piston if the old rings are to bere-used.3 Scrape away all traces of carbon from thetop of the piston. A hand-held wire brush (or apiece of fine emery cloth) can be used, oncethe majority of the deposits have beenscraped away.

4 Remove the carbon from the ring groovesin the piston, using an old ring. Break the ringin half to do this (be careful not to cut yourfingers - piston rings are sharp). Be careful toremove only the carbon deposits - do notremove any metal, and do not nick or scratchthe sides of the ring grooves.5 Once the deposits have been removed,clean the piston/connecting rod assemblywith paraffin or a suitable solvent, and drythoroughly. Make sure that the oil return holesin the ring grooves are clear.6 If the pistons and cylinder bores are notdamaged or worn excessively, and if thecylinder block does not need to be rebored,the original pistons can be refitted. Normalpiston wear shows up as even vertical wearon the piston thrust surfaces, and slightlooseness of the top ring in its groove. Newpiston rings should always be used when theengine is reassembled.7 Carefully inspect each piston for cracksaround the skirt, around the gudgeon pinholes, and at the piston ring “lands” (betweenthe ring grooves).8 Look for scoring and scuffing on the pistonskirt, holes in the piston crown, and burnedareas at the edge of the crown. If the skirt isscored or scuffed, the engine may have beensuffering from overheating, and/or abnormalcombustion which caused excessively highoperating temperatures. The cooling andlubrication systems should be checkedthoroughly. Scorch marks on the sides of thepistons show that blow-by has occurred. Ahole in the piston crown, or burned areas atthe edge of the piston crown, indicates thatabnormal combustion (pre-ignition, knocking,or detonation) has been occurring. If any ofthe above problems exist, the causes must beinvestigated and corrected, or the damage willoccur again. The causes may includeincorrect ignition/injection pump timing, or afaulty injector (as applicable).9 Corrosion of the piston, in the form ofpitting, indicates that coolant has beenleaking into the combustion chamber and/orthe crankcase. Again, the cause must becorrected, or the problem may persist in therebuilt engine.10 On aluminium-block engines with wetliners, it is not possible to renew the pistonsseparately; pistons are only supplied with

piston rings and a liner, as a part of a matchedassembly (see Section 12). On iron-blockengines, pistons can be purchased from aPeugeot dealer.11 Examine each connecting rod carefully forsigns of damage, such as cracks around thebig-end and small-end bearings. Check thatthe rod is not bent or distorted. Damage ishighly unlikely, unless the engine has beenseized or badly overheated. Detailed checkingof the connecting rod assembly can only becarried out by a Peugeot dealer or enginerepair specialist with the necessaryequipment.12 On XU series engines, due to thetightening procedure for the connecting rodbig-end cap retaining nuts, it is highlyrecommended that the big-end cap nuts andbolts are renewed as a complete set prior torefitting.13 On all 8-valve engines the gudgeon pinsare an interference fit in the connecting rodsmall-end bearing. Therefore, piston and/orconnecting rod renewal should be entrustedto a Peugeot dealer or engine repairspecialist, who will have the necessary toolingto remove and install the gudgeon pins.14 On 16-valve engines, the gudgeon pinsare of the floating type, secured in position bytwo circlips. On these engines, the pistonsand connecting rods can be separated asfollows.15 Using a small flat-bladed screwdriver,prise out the circlips, and push out thegudgeon pin (see illustrations). Handpressure should be sufficient to remove thepin. Identify the piston and rod to ensure

correct reassembly. Discard the circlips - newones must be used on refitting.16 Examine the gudgeon pin and connectingrod small-end bearing for signs of wear ordamage. Wear can be cured by renewing boththe pin and bush. Bush renewal, however, is aspecialist job - press facilities are required,and the new bush must be reamed accurately.17 The connecting rods themselves shouldnot be in need of renewal, unless seizure orsome other major mechanical failure hasoccurred. Check the alignment of theconnecting rods visually, and if the rods arenot straight, take them to an engine overhaulspecialist for a more detailed check.18 Examine all components, and obtain anynew parts from your Peugeot dealer. If newpistons are purchased, they will be suppliedcomplete with gudgeon pins and circlips.Circlips can also be purchased individually.19 Position the piston so that the arrow onthe piston crown is positioned as shown inrelation to the connecting rod big-end bearingshell cutouts (see illustration). Apply a smearof clean engine oil to the gudgeon pin. Slide itinto the piston and through the connectingrod small-end. Check that the piston pivotsfreely on the rod, then secure the gudgeon pinin position with two new circlips. Ensure thateach circlip is correctly located in its groove inthe piston.

14 Crankshaft - inspection 2Checking crankshaft endfloat1 If the crankshaft endfloat is to be checked,this must be done when the crankshaft is stillinstalled in the cylinder block/crankcase, butis free to move (see Section 11).2 Check the endfloat using a dial gauge incontact with the end of the crankshaft. Pushthe crankshaft fully one way, and then zerothe gauge. Push the crankshaft fully the otherway, and check the endfloat. The result canbe compared with the specified amount, andwill give an indication as to whether newthrustwashers are required (see illustration).3 If a dial gauge is not available, feeler bladescan be used. First push the crankshaft fullytowards the flywheel/driveplate end of theengine, then use feeler blades to measure thegap between the web of No 2 crankpin andthe thrustwasher (see illustration).

Inspection4 Clean the crankshaft using paraffin or asuitable solvent, and dry it, preferably withcompressed air if available. Be sure to cleanthe oil holes with a pipe cleaner or similarprobe, to ensure that they are not obstructed.

5 Check the main and big-end bearingjournals for uneven wear, scoring, pitting andcracking.6 Big-end bearing wear is accompanied bydistinct metallic knocking when the engine isrunning (particularly noticeable when theengine is pulling from low speed) and someloss of oil pressure.7 Main bearing wear is accompanied bysevere engine vibration and rumble - gettingprogressively worse as engine speedincreases - and again by loss of oil pressure.8 Check the bearing journal for roughness byrunning a finger lightly over the bearingsurface. Any roughness (which will beaccompanied by obvious bearing wear)indicates that the crankshaft requiresregrinding (where possible) or renewal.9 If the crankshaft has been reground, checkfor burrs around the crankshaft oil holes (theholes are usually chamfered, so burrs shouldnot be a problem unless regrinding has beencarried out carelessly). Remove any burrs witha fine file or scraper, and thoroughly clean theoil holes as described previously.10 Using a micrometer, measure thediameter of the main and big-end bearingjournals, and compare the results with theSpecifications (see illustration). Bymeasuring the diameter at a number of pointsaround each journal’s circumference, you willbe able to determine whether or not thejournal is out-of-round. Take themeasurement at each end of the journal, nearthe webs, to determine if the journal istapered. Compare the results obtained withthose given in the Specifications. Where nospecified journal diameters are quoted, seekthe advice of a Peugeot dealer.11 Check the oil seal contact surfaces ateach end of the crankshaft for wear anddamage. If the seal has worn a deep groove inthe surface of the crankshaft, consult anengine overhaul specialist; repair may bepossible, but otherwise a new crankshaft willbe required.12 At the time of writing, it was not clearwhether Peugeot produce oversize bearingshells for all of these engines. On someengines, if the crankshaft journals have notalready been reground, it may be possible tohave the crankshaft reconditioned, and to fit

15 Main and big-end bearings -inspection 2

1 Even though the main and big-end bearingsshould be renewed during the engineoverhaul, the old bearings should be retainedfor close examination, as they may revealvaluable information about the condition ofthe engine. The bearing shells are graded bythickness, the grade of each shell beingindicated by the colour code marked on it.2 Bearing failure can occur due to lack oflubrication, the presence of dirt or otherforeign particles, overloading the engine, orcorrosion (see illustration). Regardless of thecause of bearing failure, the cause must becorrected (where applicable) before theengine is reassembled, to prevent it fromhappening again.3 When examining the bearing shells, removethem from the cylinder block/crankcase, themain bearing ladder/caps (as appropriate), theconnecting rods and the connecting rod big-end bearing caps. Lay them out on a cleansurface in the same general position as theirlocation in the engine. This will enable you tomatch any bearing problems with thecorresponding crankshaft journal. Do nottouch any shell’s bearing surface with yourfingers while checking it, or the delicatesurface may be scratched.4 Dirt and other foreign matter gets into theengine in a variety of ways. It may be left inthe engine during assembly, or it may passthrough filters or the crankcase ventilationsystem. It may get into the oil, and from thereinto the bearings. Metal chips from machiningoperations and normal engine wear are oftenpresent. Abrasives are sometimes left inengine components after reconditioning,especially when parts are not thoroughlycleaned using the proper cleaning methods.Whatever the source, these foreign objectsoften end up embedded in the soft bearingmaterial, and are easily recognised. Largeparticles will not embed in the bearing, andwill score or gouge the bearing and journal.The best prevention for this cause of bearingfailure is to clean all parts thoroughly, andkeep everything spotlessly-clean duringengine assembly. Frequent and regular engineoil and filter changes are also recommended.5 Lack of lubrication (or lubricationbreakdown) has a number of interrelatedcauses. Excessive heat (which thins the oil),overloading (which squeezes the oil from thebearing face) and oil leakage (from excessivebearing clearances, worn oil pump or highengine speeds) all contribute to lubrication

breakdown. Blocked oil passages, whichusually are the result of misaligned oil holes ina bearing shell, will also oil-starve a bearing,and destroy it. When lack of lubrication is thecause of bearing failure, the bearing materialis wiped or extruded from the steel backing ofthe bearing. Temperatures may increase tothe point where the steel backing turns bluefrom overheating.6 Driving habits can have a definite effect onbearing life. Full-throttle, low-speed operation(labouring the engine) puts very high loads onbearings, tending to squeeze out the oil film.These loads cause the bearings to flex, whichproduces fine cracks in the bearing face(fatigue failure). Eventually, the bearingmaterial will loosen in pieces, and tear awayfrom the steel backing.7 Short-distance driving leads to corrosion ofbearings, because insufficient engine heat isproduced to drive off the condensed waterand corrosive gases. These products collectin the engine oil, forming acid and sludge. Asthe oil is carried to the engine bearings, theacid attacks and corrodes the bearingmaterial.8 Incorrect bearing installation during engineassembly will lead to bearing failure as well.Tight-fitting bearings leave insufficient bearingrunning clearance, and will result in oilstarvation. Dirt or foreign particles trappedbehind a bearing shell result in high spots onthe bearing, which lead to failure.9 Do not touch any shell’s bearing surfacewith your fingers during reassembly; there is arisk of scratching the delicate surface, or ofdepositing particles of dirt on it.10 As mentioned at the beginning of thisSection, the bearing shells should be renewedas a matter of course during engine overhaul;to do otherwise is false economy. Refer toSection 18 for details of bearing shellselection.

16 Engine overhaul - reassemblysequence

1 Before reassembly begins, ensure that allnew parts have been obtained, and that allnecessary tools are available. Read throughthe entire procedure carefully to familiariseyourself with the work involved, and to ensurethat all items necessary for reassembly of theengine are at hand. In addition to all normaltools and materials, thread-locking compoundwill be needed. A suitable tube of liquidsealant will also be required for the joint facesthat are fitted without gaskets. It isrecommended that Peugeot’s own product(s)are used, which are specially formulated forthis purpose.2 In order to save time and avoid problems,engine reassembly can be carried out in thefollowing order:

a) Crankshaft (Section 18).b) Piston/connecting rod assemblies

(Section 19).c) Oil pump .d) Sump (See Part A or B - as applicable).e) Flywheel (See Part A or B - as applicable).f) Cylinder head (See Part A or B - as

applicable).g) Timing belt tensioner and sprockets, and

timing belt (See Part A or B - asapplicable).

h) Engine external components.

3 At this stage, all engine components shouldbe absolutely clean and dry, with all faultsrepaired. The components should be laid out(or in individual containers) on a completelyclean work surface.

17 Piston rings - refitting 31 Before fitting new piston rings, the ring endgaps must be checked as follows.2 Lay out the piston/connecting rodassemblies and the new piston ring sets, sothat the ring sets will be matched with thesame piston and cylinder during the end gapmeasurement and subsequent enginereassembly.3 Insert the top ring into the first cylinder, andpush it down the bore using the top of thepiston. This will ensure that the ring remainssquare with the cylinder walls. Position thering near the bottom of the cylinder bore, atthe lower limit of ring travel. Note that the topand second compression rings are different.The second ring is easily identified by the stepon its lower surface, and by the fact that itsouter face is tapered.4 Measure the end gap using feeler blades.5 Repeat the procedure with the ring at thetop of the cylinder bore, at the upper limit ofits travel, and compare the measurements

with the figures given in the Specifications(see illustration). Where no figures are given,seek the advice of a Peugeot dealer or enginereconditioning specialist.6 If the gap is too small (unlikely if genuinePeugeot parts are used), it must be enlarged,or the ring ends may contact each otherduring engine operation, causing seriousdamage. Ideally, new piston rings providingthe correct end gap should be fitted. As a lastresort, the end gap can be increased by filingthe ring ends very carefully with a fine file.Mount the file in a vice equipped with softjaws, slip the ring over the file with the endscontacting the file face, and slowly move thering to remove material from the ends. Takecare, as piston rings are sharp, and are easilybroken.7 With new piston rings, it is unlikely that theend gap will be too large. If the gaps are toolarge, check that you have the correct ringsfor your engine and for the particular cylinderbore size.8 Repeat the checking procedure for eachring in the first cylinder, and then for the ringsin the remaining cylinders. Remember to keeprings, pistons and cylinders matched up.9 Once the ring end gaps have been checkedand if necessary corrected, the rings can befitted to the pistons.10 Fit the piston rings using the sametechnique as for removal. Fit the bottom (oilcontrol) ring first, and work up. When fittingthe oil control ring, first insert the expander(where fitted), then fit the ring with its gappositioned 180° from the expander gap.Ensure that the second compression ring isfitted the correct way up, with its identificationmark (either a dot of paint or the word “TOP”stamped on the ring surface) at the top, andthe stepped surface at the bottom (seeillustration). Arrange the gaps of the top andsecond compression rings 120° either side ofthe oil control ring gap. Note: Always followany instructions supplied with the new pistonring sets - different manufacturers may specifydifferent procedures. Do not mix up the topand second compression rings, as they havedifferent cross-sections.

18 Crankshaft - refitting andmain bearing runningclearance check

4Selection of new bearing shellsTU series engine1 On early engines, both upper and lowermain bearing shells were of the samethickness, with only two sizes of bearingshells being available: a standard size for usewith the standard crankshaft, and a set ofoversize bearing shells for use once thecrankshaft bearing journals have beenreground.2 However, since February 1992, thespecified main bearing running clearance hasbeen significantly reduced. This has beenachieved by the introduction of three differentgrades of bearing shell, in both standard sizesand oversizes. The grades are indicated by acolour-coding marked on the edge of eachshell, which denotes the shell’s thickness, aslisted in the following table. The upper shell onall bearings is of the same size (class B,colour code black), and the running clearanceis controlled by fitting a lower bearing shell of

the required thickness. This arrangement hasbeen fitted to all engines produced sinceFebruary 1992 and, if possible, should also befitted to earlier engines during overhaul. Seekthe advice of your Peugeot dealer on partsavailability and the best course of action whenordering new bearing shells.

3 On early engines, the correct size of bearingshell must be selected by measuring therunning clearance as described under thesub-heading below.4 On engines produced since February 1992,when the new bearing shell sizes wereintroduced, the crankshaft and cylinderblock/crankcase have reference marks onthem, to identify the size of the journals andbearing bores.5 The cylinder block reference marks are onthe right-hand (timing belt) end of the block,and the crankshaft reference marks are on theright-hand (timing belt) end of the crankshaft,on the right-hand web of No 4 crankpin (seeillustration). These marks can be used toselect bearing shells of the required thicknessas follows.6 On both the crankshaft and block there aretwo lines of identification: a bar code, which isused by Peugeot during production, and arow of five letters. The first letter in thesequence refers to the size of No 1 bearing (atthe flywheel/driveplate end). The last letter inthe sequence (which is followed by an arrow)refers to the size of No 5 main bearing. Thesemarks can be used to select the requiredbearing shell grade as follows.7 Obtain the identification letter of both therelevant crankshaft journal and the cylinderblock bearing bore.

block letters are listed across the top of thechart, and the crankshaft letters down theside, trace a vertical line down from therelevant cylinder block letter, and a horizontalline across from the relevant crankshaft letter,and find the point at which both lines cross.This crossover point will indicate the grade oflower bearing shell required to give thecorrect main bearing running clearance. Forexample, the illustration shows cylinder blockreference G, and crankshaft reference T,crossing at a point within the area of Class A,indicating that a blue-coded (Class A) lowerbearing shell is required to give the correctmain bearing running clearance (seeillustration).8 Repeat this procedure so that the requiredbearing shell grade is obtained for each of thefive main bearing journals.

XU series engine9 On some early engines, both the upper andlower bearing shells were of the samethickness.10 However, on later engines the mainbearing running clearance was significantlyreduced. To enable this to be done, fourdifferent grades of bearing shell wereintroduced. The grades are indicated by acolour-coding marked on the edge of eachshell, which denotes the shell’s thickness, aslisted in the following table. The upper shell onall bearings is of the same size, and therunning clearance is controlled by fitting alower bearing shell of the required thickness.Note: On all XU series engines, upper shellsare easily distinguished from lower shells, bytheir grooved bearing surface; the lower shellshave a plain surface. It was not clear at the time of writing whether undersize bearingshells are available for 1998 cc engine. Referto your Peugeot dealer for the latestinformation.

11 On most later engines, new bearing shellscan be selected using the reference marks onthe cylinder block/crankcase. The cylinderblock marks identify the diameter of thebearing bores, and the crankshaft marks thediameter of the crankshaft journals. Where nomarks are present, the bearing shells can onlybe selected by checking the runningclearance (see below).12 The cylinder block reference marks are onthe left-hand (flywheel/driveplate) end of theblock, and the crankshaft reference marks areon the end web of the crankshaft (seeillustration). These marks can be used toselect bearing shells of the required thicknessas follows.13 On both the crankshaft and block thereare two lines of identification: a bar code,which is used by Peugeot during production,and a row of five letters. The first letter in thesequence refers to the size of No 1 bearing (at

the flywheel/driveplate end). The last letter inthe sequence (which is followed by an arrow)refers to the size of No 5 main bearing. Thesemarks can be used to select the requiredbearing shell grade as follows.14 Obtain the identification number/letter ofboth the relevant crankshaft journal and thecylinder block bearing bore. Noting that thecrankshaft references are listed across thetop of the chart, and the cylinder blockreferences down the side, trace a vertical linedown from the relevant crankshaft reference,and a horizontal line across from the relevantcylinder block reference, and find the point atwhich both lines cross. This crossover pointwill indicate the grade of lower bearing shellrequired to give the correct main bearingrunning clearance. For example, theillustration shows crankshaft reference 6, andcylinder block reference H, crossing at a pointwithin the RED area, indicating that a Red-coded (Class D) lower bearing shell is requiredto give the correct main bearing runningclearance (see illustration).15 Repeat this procedure so that therequired bearing shell grade is obtained foreach of the five main bearing journals.16 Seek the advice of your Peugeot dealeron parts availability, and on the best course ofaction when ordering new bearing shells.Note: On early models, at overhaul it isrecommended that the later bearing shellarrangement is fitted. This, however, shouldonly be done if the lubrication systemcomponents are upgraded (necessitatingreplacement of the oil pump relief valve pistonand spring as well as the pump sprocket and

drive chain) at the same time. If the newbearing arrangement is to be used withoutuprating the lubrication system, Peugeot statethat Blue (Class A) lower bearing shells shouldbe fitted. Refer to your Peugeot dealer forfurther information.17 Since there are no bearing identificationmarks, the relevant main bearing shell grademust be selected by measuring the mainbearing running clearance.

Main bearing running clearance checkTU series engine18 On early engines, if the modified bearingshells are to be fitted, obtain a set of newblack (Class B) upper bearing shells and newblue (Class A) lower bearing shells. On later(February 1992-on) engines where themodified bearing shells are already fitted, therunning clearance check can be carried outusing the original bearing shells. However, it ispreferable to use a new set, since the resultsobtained will be more conclusive.19 Clean the backs of the bearing shells, andthe bearing locations in both the cylinderblock/crankcase and the main bearing ladder.20 Press the bearing shells into theirlocations, ensuring that the tab on each shellengages in the notch in the cylinder

block/crankcase or main bearing ladderlocation. Take care not to touch any shell’sbearing surface with your fingers. Note thatthe grooved bearing shells, both upper andlower, are fitted to Nos 2 and 4 main bearings(see illustration). If the original bearing shellsare being used for the check, ensure that theyare refitted in their original locations. Theclearance can be checked in either of twoways.21 One method (which will be difficult toachieve without a range of internalmicrometers or internal/external expandingcalipers) is to refit the main bearing laddercasting to the cylinder block/crankcase, withthe bearing shells in place. With the castingretaining bolts correctly tightened, measurethe internal diameter of each assembled pairof bearing shells. If the diameter of eachcorresponding crankshaft journal is measuredand then subtracted from the bearing internaldiameter, the result will be the main bearingrunning clearance.22 The second (and more accurate) methodis to use a product known as “Plastigauge”.This consists of a fine thread of perfectly-round plastic, which is compressed betweenthe bearing shell and the journal. When theshell is removed, the plastic is deformed, andcan be measured with a special card gauge

supplied with the kit. The running clearance isdetermined from this gauge. Plastigaugeshould be available from your Peugeot dealer,otherwise enquiries at one of the largerspecialist motor factors should produce thename of a stockist in your area. Theprocedure for using Plastigauge is as follows.23 With the main bearing upper shells inplace, carefully lay the crankshaft in position.Do not use any lubricant; the crankshaftjournals and bearing shells must be perfectlyclean and dry.24 Cut several lengths of the appropriate-size Plastigauge (they should be slightlyshorter than the width of the main bearings),and place one length on each crankshaftjournal axis (see illustration).25 With the main bearing lower shells inposition, refit the main bearing ladder casting,tightening its retaining bolts as described inparagraph 45. Take care not to disturb thePlastigauge, and do not rotate the crankshaftat any time during this operation.26 Remove the main bearing ladder casting,again taking great care not to disturb thePlastigauge or rotate the crankshaft.27 Compare the width of the crushedPlastigauge on each journal to the scaleprinted on the Plastigauge envelope, to obtainthe main bearing running clearance (seeillustration). Compare the clearancemeasured with that given in the Specificationsat the start of this Chapter.28 If the clearance is significantly differentfrom that expected, the bearing shells may bethe wrong size (or excessively worn, if theoriginal shells are being re-used). Beforedeciding that different-size shells are required,make sure that no dirt or oil was trappedbetween the bearing shells and the caps orblock when the clearance was measured. Ifthe Plastigauge was wider at one end than atthe other, the crankshaft journal may betapered.29 If the clearance is not as specified, usethe reading obtained, along with the shellthicknesses quoted above, to calculate thenecessary grade of bearing shells required.When calculating the bearing clearancerequired, bear in mind that it is always betterto have the running clearance towards the

Use yourfingernail, or a wooden or plastic scraperwhich is unlikely to score the bearingsurfaces.

XU series engine32 On early engines, if the later bearing shellsare to be fitted, obtain a set of new upperbearing shells, and new green or grey (asapplicable) lower bearing shells (seeparagraph 10). On later engines where themodified bearing shells are already fitted, therunning clearance check can be carried outusing the original bearing shells. However, it ispreferable to use a new set, since the resultsobtained will be more conclusive.33 Clean the backs of the bearing shells, andthe bearing locations in both the cylinderblock/crankcase and the main bearing caps.34 Press the bearing shells into theirlocations, ensuring that the tab on each shellengages in the notch in the cylinderblock/crankcase or bearing cap. Take carenot to touch any shell’s bearing surface withyour fingers. Note that the upper bearingshells all have a grooved bearing surface,whereas the lower shells have a plain bearingsurface (see illustration). If the original

bearing shells are being used for the check,ensure that they are refitted in their originallocations.35 The clearance can be checked in two ways.36 One method (which will be difficult toachieve without a range of internalmicrometers or internal/external expandingcalipers) is to refit the main bearing caps tothe cylinder block/crankcase, with bearingshells in place. With the cap retaining boltstightened to the specified torque, measure theinternal diameter of each assembled pair ofbearing shells. If the diameter of eachcorresponding crankshaft journal is measuredand then subtracted from the bearing internaldiameter, the result will be the main bearingrunning clearance.37 The second, and more accurate, methodis to use Plastigauge. The method is asdescribed above in paragraphs 17 to 26,substituting “main bearing caps” for allreferences to the main bearing ladder casting.38 Note that Peugeot do not specify a mainbearing running clearance for 1905 ccengines. The figure given in the Specificationsis a guide figure which is typical for this typeof engine. On these engines, therefore, alwaysrefer to your Peugeot dealer for details of theexact running clearance before condemningthe components concerned.

Peugeot garages use the toolshown, which acts as a clamp. Metal strips(such as old feeler blades) can be used,provided all burrs which may damage thesealing strips are first removed (seeillustrations).73 Where applicable, oil both sides of themetal strips, and hold them on the sealingstrips. Fit the No 1 main bearing cap, insertthe bolts loosely, then carefully pull out themetal strips in a horizontal direction, using apair of pliers (see illustrations).74 Tighten all the main bearing capbolts/nuts evenly to the specified torque.Using a sharp knife, trim off the ends of theNo 1 bearing cap sealing strips, so that theyprotrude above the cylinder block/crankcasemating surface by approximately 1 mm (seeillustrations).75 On 1580 cc, 1761 cc and 1905 ccengines, refit the centre main bearing sideretaining bolts and sealing washers (one at thefront of the block, and one at the rear) andtighten them both to the specified torque.76 Fit a new crankshaft rear oil seal asdescribed in Part B of this Chapter.77 Refit the piston/connecting rodassemblies to the crankshaft as described inSection 19.

19 Piston/connecting rodassembly - refitting and big-end bearing clearance check

4Selection of bearing shells1 On most engines, there are two sizes ofbig-end bearing shell produced by Peugeot; astandard size for use with the standardcrankshaft, and an oversize for use once thecrankshaft journals have been reground.

2 Consult your Peugeot dealer for the latestinformation on parts availability. To be safe,always quote the diameter of the crankshaftbig-end crankpins when ordering bearingshells.3 Prior to refitting the piston/connecting rodassemblies, the big-end bearing runningclearance should be checked as follows.

Big-end bearing running clearance check4 Clean the backs of the bearing shells, andthe bearing locations in both the connectingrod and bearing cap.5 Press the bearing shells into their locations,ensuring that the tab on each shell engages inthe notch in the connecting rod and cap. Takecare not to touch any shell’s bearing surfacewith your fingers (see illustration). If the

original bearing shells are being used for thecheck, ensure that they are refitted in theiroriginal locations. The clearance can bechecked in either of two ways.6 One method is to refit the big-end bearingcap to the connecting rod, ensuring that theyare fitted the correct way around (seeparagraph 20), with the bearing shells inplace. With the cap retaining nuts correctlytightened, use an internal micrometer orvernier caliper to measure the internaldiameter of each assembled pair of bearingshells. If the diameter of each correspondingcrankshaft journal is measured and thensubtracted from the bearing internal diameter,the result will be the big-end bearing runningclearance.7 The second, and more accurate, method isto use Plastigauge (see Section 18).8 Ensure that the bearing shells are correctlyfitted. Place a strand of Plastigauge on each(cleaned) crankpin journal.9 Refit the (clean) piston/connecting rodassemblies to the crankshaft, and refit thebig-end bearing caps, using the marks madeor noted on removal to ensure that they arefitted the correct way around.10 Tighten the bearing cap nuts as describedbelow in paragraph 21 or 22 (as applicable).Take care not to disturb the Plastigauge orrotate the connecting rod during thetightening sequence.11 Dismantle the assemblies without rotatingthe connecting rods. Use the scale printed onthe Plastigauge envelope to obtain the big-end bearing running clearance.12 If the clearance is significantly differentfrom that expected, the bearing shells may bethe wrong size (or excessively worn, if theoriginal shells are being re-used). Make surethat no dirt or oil was trapped between thebearing shells and the caps or block when theclearance was measured. If the Plastigaugewas wider at one end than at the other, thecrankshaft journal may be tapered.13 Note that Peugeot do not specify arecommended big-end bearing runningclearance. The figure given in the Specifica-tions is a guide figure, which is typical for this

type of engine. Before condemning thecomponents concerned, refer to your Peugeotdealer or engine reconditioning specialist forfurther information on the specified runningclearance. Their advice on the best course ofaction to be taken can then also be obtained.14 On completion, carefully scrape away alltraces of the Plastigauge material from thecrankshaft and bearing shells. Use yourfingernail, or some other object which isunlikely to score the bearing surfaces.

Final piston/connecting rodrefitting15 Note that the following procedureassumes that the cylinder liners (where fitted)are in position in the cylinder block/crankcaseas described in Section 12, and that thecrankshaft and main bearing ladder/caps arein place (see Section 18).16 Ensure that the bearing shells arecorrectly fitted as described earlier. If newshells are being fitted, ensure that all traces ofthe protective grease are cleaned off usingparaffin. Wipe dry the shells and connectingrods with a lint-free cloth.17 Lubricate the cylinder bores, the pistons,and piston rings, then lay out eachpiston/connecting rod assembly in itsrespective position.18 Start with assembly No 1. Make sure thatthe piston rings are still spaced as describedin Section 17, then clamp them in positionwith a piston ring compressor.19 Insert the piston/connecting rod assemblyinto the top of cylinder/liner No 1. On petrolengines, ensure that the arrow on the pistoncrown is pointing towards the timing belt endof the engine and on Diesel engines ensurethat the cloverleaf-shaped cut-out on thepiston crown is towards the front (oil filterside) of the cylinder block. Using a block ofwood or hammer handle against the pistoncrown, tap the assembly into the cylinder/lineruntil the piston crown is flush with the top ofthe cylinder/liner (see illustration).20 Ensure that the bearing shell is stillcorrectly installed. Liberally lubricate thecrankpin and both bearing shells. Taking carenot to mark the cylinder/liner bores, pull the

piston/connecting rod assembly down thebore and onto the crankpin. Refit the big-endbearing cap, tightening its retaining nutsfinger-tight at first. Note that the faces withthe identification marks must match (whichmeans that the bearing shell locating tabsabut each other). 21 On TU series engines, tighten the bearingcap retaining nuts evenly and progressively tothe specified torque setting.22 On XU series engines, tighten the bearingcap retaining nuts evenly and progressively tothe stage 1 torque setting. Fully slacken bothnuts, then tighten them to the stage 2 torquesetting. Once both nuts have been tightenedto the stage 2 setting, angle-tighten themthrough the specified stage 3 angle, using asocket and extension bar. It is recommendedthat an angle-measuring gauge is used duringthis stage of the tightening, to ensureaccuracy (see illustrations). If a gauge is notavailable, use a dab of white paint to makealignment marks between the nut and bearingcap prior to tightening; the marks can then beused to check that the nut has been rotatedsufficiently during tightening.23 On all engines, once the bearing capretaining nuts have been correctly tightened,rotate the crankshaft. Check that it turnsfreely; some stiffness is to be expected if newcomponents have been fitted, but thereshould be no signs of binding or tight spots.24 Refit the remaining three piston/connecting rod assemblies in the same way.25 Refit the cylinder head and oil pump asdescribed in Part A or B of this Chapter (asapplicable).

disconnecting the ignition HT coil lead fromthe distributor cap, and earthing it on thecylinder block. Use a jumper lead or similarwire to make a good connection. On modelswith a static (distributorless) ignition system,disable the ignition system by disconnectingthe LT wiring connector from the ignition HTcoil, referring to Chapter 5B for information.3 Turn the engine on the starter until the oilpressure warning light goes out. Refit thespark plugs, and reconnect the spark plug(HT) leads, referring to Chapter 1 for furtherinformation. Reconnect any HT leads or wiringwhich was disconnected in paragraph 2.4 Start the engine, noting that this may take a

little longer than usual, due to the fuel systemcomponents having been disturbed.5 While the engine is idling, check for fuel,water and oil leaks. Don’t be alarmed if thereare some odd smells and smoke from partsgetting hot and burning off oil deposits. On16-valve engines, some valvegear noise maybe heard at first; this should disappear as theoil circulates fully around the engine, andnormal pressure is restored in the hydraulictappet mechanism.6 Assuming all is well, keep the engine idlinguntil hot water is felt circulating through thetop hose, then switch off the engine.7 Check the ignition timing and the idle

speed settings, then switch the engine off.8 After a few minutes, recheck the oil andcoolant levels as described in Chapter 1, andtop-up as necessary.9 If they were tightened as described, there isno need to re-tighten the cylinder head boltsonce the engine has first run after reassembly.10 If new pistons, rings or crankshaftbearings have been fitted, the engine must betreated as new, and run-in for the first 500 miles (800 km). Do not operate the engineat full-throttle, or allow it to labour at lowengine speeds in any gear. It is recommendedthat the oil and filter be changed at the end ofthis period.

1 General information andprecautions

General informationThe cooling system is of pressurised type,

comprising a coolant pump driven by thetiming belt, an aluminium crossflow radiatorwith integral expansion tank, electric coolingfan(s), a thermostat, heater matrix, and allassociated hoses and switches.

The system functions as follows. Coldcoolant in the bottom of the radiator passesthrough the bottom hose to the coolant pump,where it is pumped around the cylinder blockand head passages, and through the oilcooler(s) (where fitted). After cooling thecylinder bores, combustion surfaces andvalve seats, the coolant reaches theunderside of the thermostat, which is initiallyclosed. The coolant passes through theheater, and is returned via the cylinder blockto the coolant pump.

When the engine is cold, the coolantcirculates only through the cylinder block,cylinder head, and heater. When the coolantreaches a predetermined temperature, thethermostat opens, and the coolant passesthrough the top hose to the radiator. As thecoolant circulates through the radiator, it iscooled by the inrush of air when the car is inforward motion. The airflow is supplementedby the action of the electric cooling fan(s)when necessary. Upon reaching the bottom ofthe radiator, the coolant has now cooled, andthe cycle is repeated.

When the engine is at normal operatingtemperature, the coolant expands, and someof it is displaced into the expansion tank,incorporated in the side of the radiator.Coolant collects in the tank, and is returned tothe radiator when the system cools.

On models with automatic transmission, aproportion of the coolant is recirculated fromthe bottom of the radiator through thetransmission fluid cooler mounted on thetransmission. On models fitted with an engineoil cooler, the coolant is also passed throughthe oil cooler.

The electric cooling fan(s) mounted in frontof the radiator are controlled by athermostatic switch. At a predeterminedcoolant temperature, the switch/sensoractuates the fan.

Precautions

2 Cooling system hoses -disconnection and renewal 2

Note: Refer to the warnings given in Section 1of this Chapter before proceeding. Hosesshould only be disconnected once the enginehas cooled sufficiently to avoid scalding.1 If the checks described in Chapter 1 reveala faulty hose, it must be renewed as follows.2 First drain the cooling system (see Chapter 1). If the coolant is not due forrenewal, it may be re-used, providing it iscollected in a clean container.3 To disconnect a hose, proceed as follows,according to the type of hose connection.

Conventional hose connections -general instructions4 On conventional connections, the clipsused to secure the hoses in position may beeither standard worm-drive clips ordisposable crimped types. The crimped typeof clip is not designed to be re-used andshould be replaced with a worm drive type onreassembly.5 To disconnect a hose, use a screwdriver toslacken or release the clips, then move themalong the hose, clear of the relevantinlet/outlet. Carefully work the hose free. Thehoses can be removed with relative easewhen new - on an older car, they may havestuck.6 If a hose proves to be difficult to remove, tryto release it by rotating its ends beforeattempting to free it. Gently prise the end of

the hose with a blunt instrument (such as aflat-bladed screwdriver), but do not apply toomuch force, and take care not to damage thepipe stubs or hoses. Note in particular that theradiator inlet stub is fragile; do not useexcessive force when attempting to removethe hose. If all else fails, cut the hose with asharp knife, then slit it so that it can be peeledoff in two pieces. Although this may proveexpensive if the hose is otherwiseundamaged, it is preferable to buying a newradiator. Check first, however, that a newhose is readily available.7 When fitting a hose, first slide the clips ontothe hose, then work the hose into position. Ifcrimped-type clips were originally fitted, usestandard worm-drive clips when refitting thehose. If the hose is stiff, use a little soapywater as a lubricant, or soften the hose bysoaking it in hot water. Do not use oil orgrease, which may attack the rubber.8 Work the hose into position, checking that itis correctly routed, then slide each clip backalong the hose until it passes over the flaredend of the relevant inlet/outlet, beforetightening the clip securely.9 Refill the cooling system with reference toChapter 1.10 Check thoroughly for leaks as soon aspossible after disturbing any part of thecooling system.

Radiator hose(s) - bayonet-type connectionNote: A new O-ring should be used whenreconnecting the hose.

Removal11 On later models, the radiator hoses areconnected to the radiator using a plasticbayonet-type connection. To disconnect thistype of connector, proceed as follows.12 Twist the end of the hose (with theconnector) anti-clockwise until the clips onthe connector are clear of the retaining lugson the radiator stub, then pull the end of thehose from the radiator. Recover the O-ringfrom the end of the hose connector (seeillustrations).

Refitting13 Fit a new O-ring to the hose connector,then reconnect the hose using a reversal of

3•2 Cooling, heating and ventilation systems

2.12a Twist the connector until the clips (A) are clear of the lugs (B)

Warning: Do not attempt toremove the expansion tank fillercap, or to disturb any part of thecooling system, while the

engine is hot, as there is a high risk ofscalding. If the expansion tank filler capmust be removed before the engine andradiator have fully cooled (even thoughthis is not recommended), the pressure inthe cooling system must first be relieved.

Cover the cap with a thick layer of cloth,to avoid scalding, and slowly unscrew thefiller cap until a hissing sound is heard.When the hissing has stopped, indicatingthat the pressure has reduced, slowlyunscrew the filler cap until it can beremoved; if more hissing sounds areheard, wait until they have stopped beforeunscrewing the cap completely. At alltimes, keep well away from the filler capopening, and protect your hands.

Do not allow antifreeze to come intocontact with your skin, or with the paintedsurfaces of the vehicle. Rinse off spillsimmediately, with plenty of water. Neverleave antifreeze lying around in an opencontainer, or in a puddle in the drivewayor on the garage floor. Children and petsare attracted by its sweet smell, butantifreeze can be fatal if ingested.

If the engine is hot, the electric coolingfan may start rotating even if the engine isnot running. Be careful to keep yourhands, hair, and any loose clothing wellclear when working in the enginecompartment.

Refer to Section 10 for precautions tobe observed when working on modelsequipped with air conditioning.

the removal procedure. Twist the end of thehose fully clockwise to ensure that theretaining clips are engaged with the lugs onthe radiator stub.

3 Radiator - removal, inspectionand refitting 3

Removal1 Disconnect the battery negative lead.2 Where applicable, disconnect the wiringfrom the coolant level sensor, mounted in theright-hand side of the radiator.3 Similarly, where applicable disconnect thewiring from the cooling fan switch, mountedleft-hand side of the radiator.4 Drain the cooling system as described inChapter 1.5 Where applicable, depress the securing

clip, and release the air inlet tube from thebody front panel, above the radiator (seeillustrations).6 Where applicable, disconnect the wiringplug and the vacuum hose from the MAPsensor, located above the radiator, thenunscrew the two bolts securing the sensormounting bracket to the body front panel, andremove the sensor.7 Disconnect the upper radiator hose fromthe left-hand end of the radiator, withreference to Section 2.8 It is now necessary to disconnect the lowerradiator hose(s) from the right-hand side ofthe radiator. On some models, particularlythose where conventional hose clips are used,this is a straightforward task. On other models(where bayonet connectors are used on alarge-capacity radiator), it is impossible togain access to the lower radiator hoseconnections without removing the body frontpanel assembly, as described in Chapter 11(see illustration).9 Once all the radiator hoses have beendisconnected, proceed as follows.10 If not already done, working at the top ofthe radiator, release the two securing clips,and tilt the radiator back towards the engine(see illustration).11 Lift the radiator from the enginecompartment (see illustration).

Inspection12 If the radiator has been removed due tosuspected blockage, reverse-flush it asdescribed in Chapter 1. Clean dirt and debrisfrom the radiator fins, using an air line (inwhich case, wear eye protection) or a soft

brush. Be careful, as the fins are sharp, andeasily damaged.13 If necessary, a radiator specialist canperform a “flow test” on the radiator, toestablish whether an internal blockage exists.14 A leaking radiator must be referred to aspecialist for permanent repair. Do notattempt to weld or solder a leaking radiator,as damage to the plastic components mayresult.15 In an emergency, minor leaks from theradiator can be cured by using a suitableradiator sealant, in accordance with itsmanufacturer’s instructions, with the radiatorin situ.16 If the radiator is to be sent for repair orrenewed, remove all hoses, and the coolingfan switch (where fitted).17 Inspect the condition of the radiatormounting rubbers, and renew them ifnecessary.

Refitting18 Refitting is a reversal of removal, bearingin mind the following points:

a) Ensure that the lower lugs on the radiatorare correctly engaged with the mountingrubbers in the body panel.

b) Reconnect the hoses with reference toSection 2, using new O-rings whereapplicable.

c) Where applicable, refit the body frontpanel assembly, referring to Chapter 11.

d) On completion, refill the cooling systemas described in Chapter 1.

Take care not to strainthe coolant hose(s) connected to the cover(see illustrations).5 Lift the thermostat from the housing, andrecover the sealing ring(s) (see illustration).

Testing6 A rough test of the thermostat may bemade by suspending it with a piece of string ina container full of water. Heat the water tobring it to the boil - the thermostat must openby the time the water boils. If not, renew it.7 If a thermometer is available, the preciseopening temperature of the thermostat maybe determined; compare with the figuresgiven in the Specifications. The openingtemperature is also marked on the thermostat.8 A thermostat which fails to close as thewater cools must also be renewed.

Refitting9 Refitting is a reversal of removal, bearing inmind the following points:a) Examine the sealing ring(s) for signs of

damage or deterioration, and if necessary,renew.

b) Ensure that the thermostat is fitted thecorrect way round, with the spring(s)facing into the housing.

c) On completion, refill the cooling systemas described in Chapter 1.

5 Electric cooling fan(s) -testing, removal and refitting 4

Testing1 Current supply to the cooling fan(s) is viathe ignition switch (see Chapter 10) and a fuse(see Chapter 12). The circuit is completed bythe cooling fan thermostatic switch, which (onmost models) is mounted in the radiator. Onmodels with air conditioning, the cooling fansare controlled by the “Bitron” sensor - seeSection 6.2 If a fan does not appear to work, run the

engine until normal operating temperature isreached, then allow it to idle. The fan shouldcut in within a few minutes (before thetemperature gauge needle enters the redsection, or before the coolant temperaturewarning light comes on). If not, switch off theignition and disconnect the wiring plug fromthe cooling fan switch. Bridge the twocontacts in the wiring plug using a length ofspare wire, and switch on the ignition. If thefan now operates, the switch is probablyfaulty, and should be renewed.3 If the fan still fails to operate, check thatbattery voltage is available at the feed wire tothe switch; if not, then there is a fault in thefeed wire (possibly due to a fault in the fanmotor, or a blown fuse). If there is no problemwith the feed, check that there is continuitybetween the switch earth terminal and a goodearth point on the body; if not, then the earthconnection is faulty, and must be re-made.4 If the switch and the wiring are in goodcondition, the fault must lie in the motor itself.The motor can be checked by disconnecting itfrom the wiring loom, and connecting a 12-volt supply directly to it.

Removal5 Remove the radiator (see Section 3).6 Remove the front grille panel (Chapter 11).7 Working behind the fan blades, unscrewthe three motor securing bolts, and withdrawthe motor/fan assembly forwards from theshroud (see illustration). The plug on themotor will be released from the wiringconnector as the motor is pulled forwards.

Refitting8 Refitting is a reversal of removal, but refitthe radiator with reference to Section 3.

6 Cooling system electricalswitches and sensors -testing, removal and refitting

2Electric cooling fan thermostaticswitch - models without airconditioning

Testing1 Testing of the switch is described inSection 5, as part of the electric cooling fantest procedure.

Removal2 The switch is located in the left-hand sideof the radiator. The engine and radiator shouldbe cold before removing the switch.3 Disconnect the battery negative lead.4 Partially drain the cooling system to justbelow the level of the switch (see Chapter 1).Alternatively, have ready a suitable bung toplug the switch aperture in the radiator whenthe switch is removed. If this method is used,take great care not to damage the radiator,and do not use anything which will allowforeign matter to enter the radiator.5 Disconnect the wiring plug from the switch.6 Carefully unscrew the switch from theradiator, and recover the sealing ring. If thesystem has not been drained, plug the switchaperture to prevent further coolant loss.

Refitting7 Refitting is a reversal of removal, using anew sealing ring. Tighten the switch, and refill(or top-up) the cooling system (see Chapter 1).8 On completion, start the engine and run ituntil it reaches normal operating temperature.Continue to run the engine, and check that thecooling fan cuts in and out correctly.

It will be self-evidentwhich type of switch is used. If no switch isfitted to the radiator, the “Bitron” sensor isused to control the fan(s).

Coolant temperature gauge/temperature warning lightsender

Testing11 The coolant temperature gauge/warninglight sender is screwed into the thermostathousing.12 The temperature gauge (where fitted) isfed with a stabilised voltage from theinstrument panel feed (via the ignition switchand a fuse). The gauge earth is controlled bythe sender. The sender contains a thermistor -an electronic component whose electricalresistance decreases at a predetermined rateas its temperature rises. When the coolant iscold, the sender resistance is high, currentflow through the gauge is reduced, and thegauge needle points towards the blue (cold)end of the scale. As the coolant temperaturerises and the sender resistance falls, currentflow increases, and the gauge needle movestowards the upper end of the scale. If thesender is faulty, it must be renewed.13 On models with a temperature warninglight, the light is fed with a voltage from theinstrument panel. The light earth is controlledby the sender. The sender is effectively aswitch, which operates at a predeterminedtemperature to earth the light and completethe circuit. If the light is fitted in addition to agauge, the senders for the gauge and light areincorporated in a single unit, with two wires,one each for the light and gauge earths. Onmodels with air conditioning, the light isoperated via the “Bitron” sensor - seeparagraphs 19 to 21.14 If the gauge develops a fault, first checkthe other instruments; if they do not work atall, check the instrument panel electrical feed.If the readings are erratic, there may be a faultin the voltage stabiliser, which will necessitaterenewal of the stabiliser (the stabiliser isintegral with the instrument panel printedcircuit board - see Chapter 12). If the fault liesin the temperature gauge alone, check it asfollows.15 If the gauge needle remains at the “cold”end of the scale when the engine is hot,disconnect the sender wiring plug, and earththe relevant wire to the cylinder head. If theneedle then deflects when the ignition isswitched on, the sender unit is proved faulty,and should be renewed. If the needle stilldoes not move, remove the instrument panel(Chapter 12) and check the continuity of thewire between the sender unit and the gauge,

and the feed to the gauge unit. If continuity isshown, and the fault still exists, then thegauge is faulty, and the gauge unit should berenewed.16 If the gauge needle remains at the “hot”end of the scale when the engine is cold,disconnect the sender wire. If the needle thenreturns to the “cold” end of the scale whenthe ignition is switched on, the sender unit isproved faulty, and should be renewed. If theneedle still does not move, check theremainder of the circuit as describedpreviously.17 The same basic principles apply to testingthe warning light. The light should illuminatewhen the relevant sender wire is earthed.

Removal and refitting18 The procedure is similar to that describedpreviously in this Section for the electriccooling fan thermostatic switch. On somemodels, access to the switch is very poor, andother components may need to be removedbefore the sender unit can be reached.

“Bitron” temperature sensor -models with air conditioning

Testing19 The sensor forms part of the airconditioning “Bitron” control system (seeSection 11). Testing of the sensor should beentrusted to a Peugeot dealer.

Removal and refitting20 The “Bitron” temperature sensor isscrewed into the thermostat housing, which isbolted onto the left-hand end of the cylinderhead.21 The procedure is similar to that describedpreviously in this Section for the electriccooling fan thermostatic switch. On somemodels, access to the switch is very poor, andother components may need to be removedbefore the sender unit can be reached.

Coolant temperature sensor -fuel injection models

Testing22 The fuel injection system coolanttemperature sensor is screwed into thethermostat housing, which is bolted onto theleft-hand end of the cylinder head.23 The sensor is a thermistor (see paragraph12). The fuel injection/engine managementelectronic control unit (ECU) supplies thesensor with a set voltage and then, bymeasuring the current flowing in the sensorcircuit, it determines the engine’stemperature. This information is then used, inconjunction with other inputs, to control theinjector opening time (pulse width). On somemodels, the idle speed and/or ignition timingsettings are also temperature-dependent.24 If the sensor circuit should fail to provideadequate information, the ECU’s back-upfacility will override the sensor signal. In thisevent, the ECU assumes a predeterminedsetting which will allow the fuel

injection/engine management system to run,albeit at reduced efficiency. When this occurs,the warning light on the instrument panel willcome on, and the advice of a Peugeot dealershould be sought. The sensor itself can onlybe tested using special Peugeot diagnosticequipment. Do not attempt to test the circuitusing any other equipment, as there is a highrisk of damaging the ECU.

Removal and refitting25 The procedure is similar to that describedpreviously in this Section for the electriccooling fan thermostatic switch. On somemodels, access to the switch is very poor, andcertain components may need to be removedbefore the sensor can be reached.

7 Coolant pump - removal and refitting 4

Note: A new pump gasket or O-ring (asapplicable) will be required on refitting.

Removal1 The coolant pump is driven by the timingbelt, and is bolted to the cylinder block at thetiming belt end of the engine. Note that on 1.4litre aluminium cylinder block engines, thecoolant pump is bolted to a separate housingwhich is in turn bolted to the side of thecylinder block.2 Drain the cooling system as described inChapter 1.3 Remove the timing belt as described inChapter 2.4 Where necessary, for access to the coolantpump, remove the timing belt tensionerand/or the rear timing belt cover as describedin Chapter 2.5 On 1.4 litre engines, support the engine byplacing a trolley jack and interposed block ofwood under the sump, then remove the upperengine mounting as described in Chapter 2.6 Remove the securing bolts, and withdrawthe pump from the cylinder block (access ismost easily obtained from under the wheelarch). Recover the gasket or the O-ring, asapplicable (see illustrations).7 On 1.4 litre aluminium cylinder blockengines, if desired, the pump impeller housingcan be removed from the rear of the coolantpump housing. Access is most easilyobtained from underneath the vehicle (it maybe necessary to remove the exhaust heatshield). Disconnect the coolant hoses fromthe impeller housing (be prepared for coolantspillage), then remove the securing bolts andwithdraw the impeller housing. Again, recoverthe O-ring.

Refitting8 Ensure that all mating faces are clean.9 Where applicable, refit the impeller housingto the pump housing, using a new O-ring.Reconnect the coolant hoses.

8 Heating and ventilationsystem - general information

1 The heating/ventilation system consists of ablower motor (housed behind the facia), facelevel vents in the centre and at each end ofthe facia, and air ducts to the front footwells.2 Two types of system are fitted to the modelrange. On basic specification models, theheating/ventilation system is manually-controlled. On higher specification models,the system is electronically-controlled. Thecomponents of both systems are identical,with the exception of the control unit.Additionally, on models with the electroni-cally-controlled system, temperature sensorsand a thermostat are fitted to automaticallycontrol the temperature of the air inside thevehicle according to the position of thetemperature control knob.3 The control unit is located in the facia, andthe controls operate flap valves to deflect andmix the air flowing through the various parts ofthe heating/ventilation system. The flap valves

are contained in the air distribution housing,which acts as a central distribution unit,passing air to the various ducts and vents.4 Cold air enters the system through the grilleat the rear of the engine compartment. Ifrequired, the airflow is boosted by the blower,and then flows through the various ducts,according to the settings of the controls. Staleair is expelled through ducts at the rear of thevehicle. If warm air is required, the cold air ispassed over the heater matrix, which isheated by the engine coolant.5 A recirculation switch enables the outsideair supply to be closed off, while the air insidethe vehicle is recirculated. This can be usefulto prevent unpleasant odours entering fromoutside the vehicle, but should only be usedbriefly, as the recirculated air inside thevehicle will soon become stale.

10 Air conditioning system -general information andprecautions

General information1 An air conditioning system is available oncertain models up to 1992, and on all modelsfrom 1993. It enables the temperature ofincoming air to be lowered, and alsodehumidifies the air, which makes for rapiddemisting and increased comfort.2 The cooling side of the system works in thesame way as a domestic refrigerator.Refrigerant gas is drawn into a belt-drivencompressor, and passes into a condensermounted on the front of the radiator, where itloses heat and becomes liquid. The liquidpasses through an expansion valve to anevaporator, where it changes from liquidunder high pressure to gas under low

pressure. This change is accompanied by adrop in temperature, which cools theevaporator. The refrigerant returns to thecompressor, and the cycle begins again.3 Air blown through the evaporator passes tothe air distribution unit, where it is mixed withhot air blown through the heater matrix toachieve the desired temperature in thepassenger compartment.4 The heating side of the system works in thesame way as on models without airconditioning (see Section 9).5 The operation of the system is controlledelectronically by the “Bitron” control unit,which controls the electric cooling fan(s), thecompressor, and the facia-mounted warninglight. Any problems with the system should bereferred to a Peugeot dealer.

Precautions6 When an air conditioning system is fitted, itis necessary to observe special precautionswhenever dealing with any part of the system,

or its associated components. If for anyreason the system must be disconnected,entrust this task to your Peugeot dealer or arefrigeration engineer.

7 The refrigerant is potentially dangerous,and should only be handled by qualifiedpersons. If it is splashed onto the skin, it cancause frostbite. It is not itself poisonous, butin the presence of a naked flame (including acigarette) it forms a poisonous gas.Uncontrolled discharging of the refrigerant isdangerous, and potentially damaging to theenvironment.8 Do not operate the air conditioning systemif it is known to be short of refrigerant, as thismay damage the compressor.

11 Air conditioning systemcomponents - removal andrefitting

The only operation which can be carried outeasily without discharging the refrigerant isrenewal of the compressor drivebelt. This isdescribed in Chapter 1. (The “Bitron”temperature sensor may be renewed usingthe information in Section 6.) All otheroperations must be referred to a Peugeotdealer or an air conditioning specialist.

If necessary, the compressor can beunbolted and moved aside, withoutdisconnecting its flexible hoses, afterremoving the drivebelt.

3•10 Cooling, heating and ventilation systems

Warning: Do not attempt toopen the refrigerant circuit.Refer to the precautions givenin Section 10.

Warning: The refrigerationcircuit may contain a liquidrefrigerant (Freon), and it istherefore dangerous to

disconnect any part of the system withoutspecialised knowledge and equipment.

1 General information andprecautions

The fuel system consists of a fuel tankmounted under the rear of the car, amechanical fuel pump, and a carburettor. Thefuel pump is operated by an eccentric on thecamshaft, and is mounted on the rear of thecylinder head. The air cleaner contains adisposable paper filter element, andincorporates a flap valve air temperaturecontrol system; this allows cold air from theoutside of the car, and warm air from theexhaust manifold, to enter the air cleaner inthe correct proportions.

The fuel pump lifts fuel from the fuel tank tothe carburettor via a filter located in the rear ofthe engine compartment, and supplies it to thecarburettor via an anti-percolation chamber.The anti-percolation chamber ensures that thesupply of fuel to the carburettor is kept at aconstant pressure, and is free of air bubbles.Excess fuel is returned from the anti-percolation chamber to the fuel tank.

The carburettor is either a Solex 34-34 Z1 orSolex 32-34 Z2 twin-choke carburettor, orWeber 36TLP single-choke carburettor (seeSection 11), mixture enrichment for cold startingis by automatic choke on the Solex carburettorand a cable-operated choke control on theWeber carburettor. On the Solex carburettor avacuum-operated choke unloader, acceleratorpump and full load enrichener device are fittedto govern the fuel requirements of the engineover its full operating range.

The exhaust system consists of three orfour sections according to model. The frontpipe is in one or two sections; where it is intwo sections the rear section may be plain orinclude a catalytic converter, where it is in onesection it may include a catalytic converter. Allmodels are fitted with an Intermediate pipeand silencer, and a tailpipe and silencer. Thesystem is suspended throughout its entirelength by rubber mountings.

2 Air cleaner assembly -removal and refitting 2

Removal

TU engine1 Slacken the retaining clips (where fitted),and disconnect the vacuum hose andbreather hose from the front of the air cleanerhousing-to-carburettor duct (see illustration).Where the crimped-type Peugeot hose clipsare fitted, cut the clips and discard them; usestandard worm-drive hose clips on refitting.2 Slacken the retaining clips, then lift the ductoff the top of the carburettor and air cleanerhousing. Disconnect the air temperaturecontrol valve hose from the end of the duct,and remove the duct from the enginecompartment (see illustrations). Recover therubber sealing ring(s) from the top of thecarburettor and/or air cleaner housing (asapplicable).3 Disconnect the inlet duct from the front of

the air cleaner housing, and remove the aircleaner housing from the enginecompartment.4 To remove the inlet duct assembly, undothe retaining bolts securing the duct to theleft-hand wing valance, then release thefastener securing the rear of the duct to thecylinder head (see illustration). Disconnectthe hot-air inlet hose from the exhaustmanifold shroud, and remove the duct andhose assembly from the engine compartment.

Before carrying outany operation on the fuel system, refer tothe precautions given in “Safety first!” atthe beginning of this manual, and followthem implicitly. Petrol is a highlydangerous and volatile liquid, and theprecautions necessary when handling itcannot be overstressed.

b) Where applicable, ensure that the aircleaner housing locating peg is correctlyengaged with its mounting on the top ofthe transmission (see illustration).

c) Prior to tightening the air cleaner-to-carburettor duct retaining clips, ensurethat the duct is correctly seated on boththe air cleaner housing and carburettorflanges.

3 Air cleaner air temperaturecontrol system - informationand component renewal

2General information

TU engine1 The system is controlled by a heat-sensitivevacuum switch, mounted in the end of the aircleaner housing-to-carburettor duct. Whenthe engine is started from cold, the switch isopen, allowing inlet manifold depression toact on the air temperature control valvediaphragm in the inlet duct. This vacuumcauses the diaphragm to rise, drawing a flapvalve across the cold-air inlet, thus allowingonly (warmed) air from the exhaust manifold toenter the air cleaner.2 As the temperature of the exhaust-warmedair in the air cleaner-to-carburettor duct rises,the wax capsule in the vacuum switchdeforms and closes the switch, cutting off thevacuum supply to the air temperature controlvalve assembly. As the vacuum supply is cut,the flap is gradually lowered across the hot-air

inlet until, when the engine is fully warmed-upto normal operating temperature, only cold airfrom the front of the car is entering the aircleaner.3 To check the system, allow the engine tocool down completely, then slacken theretaining clip and disconnect the inlet ductfrom the front of the control valve assembly;the flap valve in the duct should be securelyseated across the hot-air inlet. Start theengine; the flap should immediately rise toclose off the cold-air inlet, and should thenlower steadily as the engine warms up, until itis eventually seated across the hot-air inletagain.4 To check the vacuum switch, disconnectthe vacuum pipe from the control valve whenthe engine is running, and place a finger overthe pipe end. When the engine is cold, fullinlet manifold vacuum should be present inthe pipe, and when the engine is at normaloperating temperature, there should be novacuum in the pipe.5 To check the air temperature control valveassembly, slacken the retaining clip anddisconnect the inlet duct from the front of thevalve assembly; the flap valve should besecurely seated across the hot-air inlet.Disconnect the vacuum pipe, and suck hardat the control valve stub; the flap should riseto shut off the cold-air inlet.6 If either component is faulty, it must berenewed.

XU engine7 Cold air is drawn into the system from theinlet duct fitted to the front panel.

8 Hot air is drawn from the collector plateover the exhaust manifold. These two ductsjoin together at the air inlet mixer housingwhich contains a control flap operated by awax thermostat (see illustrations).9 When the engine is cold the thermostatcontracts and the control flap closes off thecold air duct and opens the hot air duct. Asthe air being collected from the exhaustmanifold becomes warmer, so the thermostatprogressively closes off the warm air duct andopens the cold air duct.10 If the thermostat should fail, renew themixer housing.11 All the ducts are held by worm drive clips.12 Additional breather pipes are connectedto the air filter housing on certain models.

Vacuum switch (TU engine) - renewal13 Remove the air cleaner housing-to-carburettor duct, as described in para-graphs 1 and 2 of Section 2.14 Bend up the tangs on the switch retainingclip, then remove the clip, along with its seal,and withdraw the switch from inside the duct(see illustrations). Examine the seal for damageor deterioration, and renew if necessary.15 On refitting, ensure that the switch andduct mating surfaces are clean and dry, andposition the switch inside the duct.16 Fit the seal over the switch unions, andrefit the retaining clip. Ensure that the switchis pressed firmly against the duct, and secureit in position by bending down the retainingclip tangs. Refit the duct as described inSection 2.

4 Fuel pump - testing, removal and refitting 2

Note: Refer to the warning note in Section 1before proceeding.

Testing1 To test the fuel pump on the engine,disconnect the outlet pipe which leads to thecarburettor. Hold a wad of rag by the pumpoutlet while an assistant spins the engine onthe starter. Keep your hands away from theelectric cooling fan. Regular spurts of fuelshould be ejected as the engine turns. Becareful not to spill fuel onto hot enginecomponents.2 The pump can also be tested by removingit. With the pump outlet pipe disconnectedbut the inlet pipe still connected, hold the wadof rag by the outlet. Operate the pump leverby hand, moving it in and out; if the pump is ina satisfactory condition, the lever shouldmove and return smoothly, and a strong jet offuel should be ejected.

Removal3 Identify the pump inlet and outlet hoses,and slacken both retaining clips (seeillustration). Where the crimped-typePeugeot hose clips are fitted, cut the clips anddiscard them; use standard worm-drive hoseclips on refitting. Place wads of rag beneaththe hose unions to catch any spilled fuel, thendisconnect both hoses from the pump; plugthe hose ends to minimise fuel loss.

TU engine4 Where fitted remove the insulating coverfrom the fuel pump, then slacken and removethe bolts securing the pump to the rear of thecylinder head. Remove the pump along withits insulating block. Check the block andrenew it if necessary.

XU engine5 Unscrew the nuts securing the pump to thedistributor end of the cylinder head and lift offthe pump (see illustration).6 Remove the insulating block from the studson the cylinder head.

Refitting7 Ensure that the pump and cylinder headmating surfaces are clean and dry, then offerup the insulating block and refit the pump tothe cylinder head. Tighten the pump retainingbolts/nuts to the specified torque, then refitthe pump insulating cover where fitted8 Reconnect the inlet and outlet hoses to therelevant pump unions, and securely tightentheir retaining clips.

5 Fuel gauge sender unit -removal and refitting 3

Note: Refer to the warning note in Section 1before proceeding.

Removal1 Disconnect the battery negative lead.

2 For access to the sender unit, fold the rearseat cushion forwards or remove the rearseats as described in Chapter 11.3 Using a screwdriver, carefully prise theplastic access cover from the floor to exposethe sender unit (see illustration).4 Disconnect the wiring connector from thesender unit (see illustration).

5 Mark the hoses for identification purposes,then slacken the feed and return hose clips.Where the crimped-type Peugeot hose clipsare fitted, cut the clips and discard them; usestandard worm-drive hose clips on refitting.Disconnect both hoses from the top of thesender unit, and plug the hose ends.6 Noting the alignment marks on the tank,sender unit and the locking ring, unscrew thering and remove it from the tank. This is bestachieved by using a screwdriver on the raisedribs of the locking ring, as follows. Carefullytap the screwdriver to turn the ring anti-clockwise until it can be unscrewed by hand.7 Carefully lift the sender unit from the top ofthe fuel tank, taking great care not to bend thesender unit float arm, or to spill fuel onto theinterior of the vehicle. Recover the rubbersealing ring and discard it - a new one mustbe used on refitting. If necessary remove thefilter from the bottom of the unit and wash it inclean fuel.

Refitting8 Refitting is a reversal of the removalprocedure, noting the following points:a) Prior to refitting, fit a new rubber sealing

ring to the sender unit.b) Refit the sender unit to the tank, aligning

its arrow with the centre of the threealignment marks on the fuel tank. Securethe sender in position with the lockingring, and check that the locking ring,sender unit and fuel tank marks are allcorrectly aligned.

c) Ensure that the feed and return hoses arecorrectly reconnected and securelyretained by their clips.

6 Fuel tank - removal and refitting 3

Note: Refer to the warning note in Section 1before proceeding.

Removal1 Before removing the fuel tank, all fuel mustbe drained from the tank. Since a fuel tankdrain plug is not provided, it is preferable tocarry out the removal operation when the tankis nearly empty. Before proceeding,disconnect the battery negative lead andsyphon or hand-pump the remaining fuel fromthe tank.2 Remove the exhaust system and relevantheat shield(s) as described in Section 16.3 From underneath the vehicle, disconnectthe handbrake cable at the equaliser bracket.4 Release the handbrake primary cable fromthe clips in the fuel tank. Position the cableclear of the tank, so that it will not hinder theremoval procedure.5 Disconnect the wiring connector from thefuel gauge sender unit, as described inSection 5.6 Working at the right-hand side of the fueltank, release the retaining clips thendisconnect the filler neck vent pipe and mainfiller neck hose from the fuel tank/filler neck.Where necessary, also disconnect thebreather hose(s). Some breather hoses arejoined to the tank with quick-release fittings; todisconnect these fittings, slide the cover along

the hose then depress the centre ring and pullthe hose out of its fitting (see illustration).7 Trace the fuel feed and return hoses backfrom the right-hand side of the tank to theirunion with the fuel pipes. Slacken theretaining clips and disconnect both hosesfrom the fuel pipes. Where the crimped-typePeugeot hose clips are fitted, cut the clips anddiscard them; use standard worm-drive hoseclips on refitting. Plug the hose and pipe ends,to prevent the entry of dirt into the system.8 Place a trolley jack with an interposed blockof wood beneath the tank, then raise the jackuntil it is supporting the weight of the tank.9 Slacken and remove the retaining nut andbolts, then remove the two support rods fromthe underside of the tank (see illustration).10 Slowly lower the fuel tank out of position,disconnecting any other relevant vent pipes asthey become accessible (where necessary),and remove the tank from underneath the car.11 If the tank is contaminated with sedimentor water, remove the sender unit (Section 5),and swill the tank out with clean fuel. The tankis injection-moulded from a synthetic material- if seriously damaged, it should be renewed.However, in certain cases, it may be possibleto have small leaks or minor damage repaired.Seek the advice of a specialist beforeattempting to repair the fuel tank.

Refitting12 Refitting is the reverse of the removalprocedure, noting the following points:

a) When lifting the tank back into position,take care to ensure that none of the hoses

become trapped between the tank andvehicle body.

b) Ensure that all pipes and hoses arecorrectly routed, and securely held inposition with their retaining clips.

c) Reconnect the handbrake cables andadjust the handbrake (see Chapter 9).

d) On completion, refill the tank with a smallamount of fuel, and check for signs ofleakage prior to taking the vehicle out onthe road.

7 Accelerator cable - removal,refitting and adjustment 2

Removal1 Working in the engine compartment, freethe accelerator inner cable from thecarburettor throttle cam, then pull the outercable out from its mounting bracket rubbergrommet (see illustrations). Where fitted,slide the flat washer off the end of the cable,and remove the spring clip.2 Working back along the length of the cable,free it from any retaining clips or ties, notingits correct routing.3 Where necessary remove the lower trimfrom below the driver’s side of the facia panel.4 Working from inside the vehicle, disconnectthe cable from the accelerator pedal bydepressing the lugs on the plastic end fittingand pushing the fitting from the pedal (seeillustration).

5 Release the outer cable from its retainer onthe pedal mounting bracket, then tie a lengthof string to the end of the cable.6 Return to the engine compartment, releasethe cable grommet from the bulkhead andwithdraw the cable. When the end of thecable appears, untie the string and leave it inposition - it can then be used to draw thecable back into position on refitting.

Refitting7 Tie the string to the end of the cable, thenuse the string to draw the cable into positionthrough the bulkhead. Once the cable end isvisible, untie the string, then clip the outercable into its pedal bracket retainer, and clipthe inner cable into position in the pedal end.The remaining procedure is a reversal ofremoval, but adjust it as follows.

Adjustment8 Remove the spring clip from the acceleratorouter cable. Ensuring that the throttle cam isfully against its stop, gently pull the cable outof its grommet until all free play is removedfrom the inner cable.9 With the cable held in this position, refit thespring clip to the last exposed outer cablegroove in front of the rubber grommet andwasher. When the clip is refitted and the outercable is released, there should be only a smallamount of free play in the inner cable (seeillustration).10 Have an assistant depress the acceleratorpedal, and check that the throttle cam opensfully and returns smoothly to its stop.11 For models fitted with automatictransmission refer to Chapter 7, Part B.

8 Accelerator pedal - removal and refitting 2

Removal1 Disconnect the accelerator cable from thepedal as described in Section 7.2 Remove the screws from the pedal pivotbush and lift out the pedal (see illustration).3 Examine the pivot bush and shaft for signsof wear, and renew as necessary.

Refitting4 Refitting is a reversal of the removalprocedure, applying a little multi-purposegrease to the pedal pivot point. Oncompletion, adjust the accelerator cable asdescribed in Section 7.

9 Choke cable - removal,refitting and adjustment 2

Removal1 Release the choke inner cable from thecarburettor linkage.2 Slacken and remove the retaining bolt andremove the outer cable retaining clamp.3 Slacken the retaining clip securing therubber collar to the outer cable, and slide thecollar off the cable. Where the originalcrimped-type Peugeot hose clip is still fitted,cut the clip and discard it; use a standardworm-drive hose clip on refitting.4 Working back along the length of the cable,free it from any retaining clips or ties, notingits correct routing. Tie a length of string to theend of the choke inner cable.5 Working from inside the vehicle, pull thechoke lever fully out, to gain access to theretaining screw. Unclip the choke lever fromthe facia and withdraw the lever and cableassembly from the facia, disconnecting thewiring from the lever switch (where fitted) as itbecomes accessible. Once the end of thecable appears through the lever aperture,untie the string and leave it in position in thevehicle - it can then be used to draw the cableback into position on refitting.

Refitting6 Tie the string to the end of the choke cable,then use the string to draw the cable intoposition through the bulkhead into the enginecompartment. Once the cable end is fully inposition, untie the string.7 Reconnect the wiring connector (wherefitted), and clip the choke lever in its faciapanel aperture.8 From within the engine compartment,ensure that the outer cable is correctly seatedin the bulkhead grommet. Work along the

cable, securing it in position with all therelevant retaining clips and ties, and ensuringthat the cable is correctly routed.9 Slide the rubber collar and retaining cliponto the end of the cable, then engage theinner end of the cable with carburettorlinkage. Align the rubber collar with thecarburettor bracket, then refit the retainingclip and securely tighten its retaining bolt.Adjust the cable as described below.

Adjustment10 Slacken the clip securing the rubber collarto the outer cable. Where the crimped-typePeugeot hose clip is still fitted, cut the clipand discard it; use a standard worm-drivehose clip on refitting (see illustration).11 Ensuring that the choke lever is flush withthe facia panel and the carburettor linkage isfully against its stop, move the outer cable inthe rubber collar until the position is foundwhere there is only a small amount of free playpresent in the inner cable. Hold the outercable in this position, and securely tighten theclip securing the rubber collar to the outercable.12 Have an assistant operate the chokelever, and check that the choke linkage closesfully and returns smoothly to its stop. Ifnecessary, repeat the adjustment procedure.

10 Unleaded petrol - generalinformation and usage

Note: The information given in this Chapter iscorrect at the time of writing. If updatedinformation is required, check with a Peugeotdealer. If travelling abroad, consult one of themotoring organisations (or a similar authority)for advice on the fuel available.

The fuel recommended by Peugeot is givenin the Specifications Section of this Chapter,followed by the equivalent petrol currently onsale in the UK.

All Peugeot 405 carburettor models aredesigned to run on 95 octane petrol. Bothleaded and unleaded petrol can be usedwithout modification. Super leaded (97 octane, UK “4-star”) and super unleaded(98 octane) petrol can also be used if wished,though there is no advantage in doing so.

e) Refit the air cleaner duct as described inSection 2.

f) On completion, check and, if necessary,adjust the idle speed and mixture settingsas described in Chapter 1.

13 Carburettor - fault diagnosis,overhaul and adjustments 2

Fault diagnosis1 If a carburettor fault is suspected, alwayscheck first that the ignition timing is correctlyset, that the spark plugs are in good conditionand correctly gapped, that the acceleratorand choke cables are correctly adjusted, andthat the air cleaner filter element is clean; referto the relevant Sections of Chapter 1, Chapter5 or this Chapter. If the engine is running veryroughly, first check the valve clearances asdescribed in Chapter 1, then check thecompression pressures as described inChapter 2.2 If careful checking of all the aboveproduces no improvement, the carburettormust be removed for cleaning and overhaul.3 Prior to overhaul, check the availability ofcomponent parts before starting work; notethat most sealing washers, screws andgaskets are available in kits, as are some ofthe major sub-assemblies. In most cases, itwill be sufficient to dismantle the carburettorand to clean the jets and passages.

OverhaulNote: Refer to the warning note in Section 1before proceeding. Only carry out theprocedures described in this Section, asspecial gauges are required for a moredetailed overhaul. The following procedureapplies to the Solex 34-34 Z1 carburettor.4 Remove the carburettor from the vehicle asdescribed in Section 12.5 Unscrew the idle cut-off solenoid from thecarburettor body, and remove it along with itsplunger and spring. To test the solenoid,connect a 12-volt battery to it (positive

terminal to the solenoid terminal, negativeterminal to the solenoid body), and check thatthe plunger is retracted fully into the body.Disconnect the battery, and check that theplunger is pushed out by spring pressure. Ifthe valve does not perform as expected, andcleaning does not improve the situation, thesolenoid valve must be renewed.6 Remove the five screws and lift off thecarburettor upper body.7 Tap out the float pivot pin and remove thefloat assembly, needle valve, and floatchamber gasket. Check that the needle valveanti-vibration ball is free in the valve end, thenexamine the needle valve tip and seat for wearor damage. Examine the float assembly andpivot pin for signs of wear and damage. Thefloat assembly must be renewed if it appearsto be leaking - shake the float to detect thepresence of fuel inside.8 Unscrew the fuel inlet union and inspect thefuel filter. Clean the filter housing of debrisand dirt, and renew the filter if it is blocked.9 Undo the four screws, detach theaccelerator pump cover, and remove thepump diaphragm and spring, noting whichway around they are fitted. Examine thediaphragm for signs of damage anddeterioration, and renew if necessary.Remove the choke pull-down diaphragm andpart-load enrichment diaphragms, andexamine them in the same way.10 Unscrew the idle jet from the upper body.11 Unscrew both the primary and secondarycombined air correction jets and emulsiontubes.12 Using a long thin screwdriver, unscrewthe main jets from the bottom of the emulsiontube drillings. Invert the carburettor and catchthe jets as they fall out of the drillings.13 Remove the idle mixture adjustmentscrew tamperproof cap. Screw the screw inuntil it seats lightly, counting the exactnumber of turns required to do this, thenunscrew it. On refitting, screw the screw inuntil it seats lightly, then back the screw off bythe number of turns noted on removal, toreturn the screw to its original position.14 Clean the jets, carburettor bodyassemblies, float chamber and internaldrillings. An air line may be used to clear theinternal passages once the carburettor is fullydismantled. Caution: If high pressure air isdirected into drillings and passages wherea diaphragm is fitted, the diaphragm islikely to be damaged.

15 Use a straight edge to check allcarburettor body assembly mating surfacesfor distortion.16 To test the carburettor heating element,connect a multimeter, set to the resistance

function, between the heater wiring terminaland the carburettor body. A resistancereading of approximately 0.25 to 0.5 ohmsshould be obtained. If an open-circuit ispresent, or an extremely high resistancereading is obtained, it is likely that the heatingelement is faulty. A heating element repair kitis available from your Peugeot dealer. Torenew the element undo the screw andremove the retaining plate, then slide theelement holder, pin, element and insulatingplate, noting each component correct fittedlocation. Fit the new components, ensuringeach one is correctly positioned, and securelytighten the retaining screws. Note: Ensurethat the insulating plate is correctly positionedbetween the heating element and body so thatthere is no danger of the element shorting outon the carburettor body.17 On reassembly renew any worncomponents and fit a complete set of newgaskets and seals. A jet kit and a gasket andseal kit are available from your Peugeotdealer.18 Reassembly is a reversal of thedismantling procedure. Ensure that all jets aresecurely locked in position, but take greatcare not to overtighten them. Ensure that allmating surfaces are clean and dry, and that allbody sections are correctly assembled withtheir fuel and air passages correctly aligned.Prior to refitting the carburettor to the vehicle,set the float height, throttle valve fast idle andchoke pull-down settings as described below.

Adjustments

Idle speed and mixture19 Refer to Chapter 1.

Float height setting (Solex carburettor)20 Invert the carburettor body, so that thefloat is at the top and the needle valve isdepressed. Measure the distance betweenthe upper edge of the float and the sealingface of the upper body (with its gasket fitted).This measurement should be as given in theSpecifications at the start of this Chapter.21 If necessary, the float height can beadjusted by carefully bending the small tangon the float arm which contacts the needlevalve.

Throttle valve fast idle setting (Solex carburettor)22 Invert the carburettor and pull thecarburettor choke linkage to fully close thechoke valve. The fast idle screw will buttagainst the fast idle cam and force the throttlevalve open slightly.23 Using the shank of a twist drill, measurethe clearance between the edge of the throttlevalve and bore, and compare this to theclearance given in the Specifications at thestart of this Chapter. If necessary, adjust byturning the fast idle adjustment screw in theappropriate direction until the specifiedclearance is obtained (see illustration).

Aerosol cans of carburettorcleaner are widely availableand can prove very useful inhelping to clear internal

passages of stubborn obstructions.

Choke pull-down setting (Solex carburettor)24 Pull the carburettor choke linkage to fullyclose the choke valve, and hold the linkage inthis position.25 Attach a hand-held vacuum pump to thechoke pull-down diaphragm, and apply avacuum to the diaphragm so that thediaphragm rod is pulled fully into thediaphragm body. In the absence of a vacuumpump, the rod can be pushed into thediaphragm with a small screwdriver.26 With the rod fully retracted, use the shankof a twist drill to measure the clearancebetween the edge of the choke valve andbore, and compare this to the clearance givenin the Specifications (see illustration). Ifnecessary, remove the plug from thediaphragm cover and adjust by turning theadjustment screw. Once the pull-down settingis correctly adjusted, refit the plug to thediaphragm cover and remove the vacuumpump (where used).

Float height setting (Weber carburettor)27 For float and level settings, remove thefloat chamber cover and hold it vertically.

28 With the gasket in position, use a steelrule or vernier calipers to check the height ofthe floats. Bend the float tongue andconnecting bars if necessary.

Choke opening after starting (Weber carburettor)29 Remove the air inlet from the top of thecarburettor. Pull the choke control knob outfully to close the choke flap.30 Disconnect the vacuum pipe from theanti-flood capsule.31 Connect a hand vacuum pump (or amodified bicycle pump) to the capsule. Applyvacuum (400 mm Hg approx.) to the capsule.The choke flap should open far enough toadmit a drill shank or rod 5 mm in diameter.32 Adjust if necessary by means of the screwon the anti-flood capsule.33 Disconnect the vacuum pump, remakethe original vacuum connection, and close thechoke flap.34 Having adjusted the anti-flood capsule,move the choke opening roller into the recessof the cam as shown (see illustration).35 Check that the choke flap opening justadmits a drill shank or rod 8 mm in diameter.36 Adjust by turning the nut shown (seeillustration) after removing the carburettor.

Disconnect the front pipe from themanifold, and where applicable recover thegasket.5 Where fitted, loosen the clamp nuts andrelease the power-assisted steering andcoolant pipes from the brackets (seeillustration).6 Undo the retaining nuts securing themanifold to the head (see illustration).Manoeuvre the manifold out of the enginecompartment, and discard the manifoldgaskets.

Refitting7 Refitting is the reverse of the removal

procedure, noting the following points:a) Examine all the exhaust manifold studs for

signs of damage and corrosion; removeall traces of corrosion, and repair orrenew any damaged studs.

b) Ensure that the manifold and cylinderhead sealing faces are clean and flat, andfit the new manifold gaskets (seeillustration). Tighten the manifoldretaining nuts to the specified torque.

c) Reconnect the front pipe to the manifoldusing the information given in Section 16.

16 Exhaust system - general information, removaland refitting

3General information1 The exhaust system sections are joined byflanged joints or clamped cone joints. Excepton TU engines the manifold to downpipe jointis of the spring-loaded ball type, to allow formovement in the exhaust system. On TUengines the spring-loaded joint is located atthe rear of the front pipe. On early modelsearth straps are fitted between the underbodyand the exhaust system (see illustration).2 The system is suspended throughout itsentire length by rubber mountings.

Removal3 Each exhaust section can be removedindividually, or alternatively, the completesystem can be removed as a unit. Even if only

one part of the system needs attention, it isoften easier to remove the whole system andseparate the sections on the bench.4 To remove the system or part of thesystem, first jack up the front or rear of the carand support it on axle stands (see “Jackingand Vehicle Support”). Alternatively, positionthe car over an inspection pit or on car ramps.

Front pipe5 Undo the nuts/bolts securing the front pipeflange joint to the manifold, and the single boltsecuring the front pipe to its mountingbracket. Separate the flange joint and collectthe gasket or spring cup and springs.6 Slacken and remove the nuts from the frontpipe rear flange joint, and recover the clampor spring cups and springs. Withdraw thefront pipe from underneath the vehicle, andrecover the gasket.

Front pipe extension7 Undo the nuts from the front pipe rearflange joint, and the clamp bolts from theextension pipe rear joint.8 Withdraw the extension from under thevehicle and recover the gaskets.

Intermediate pipe9 Undo the clamp bolts at each end of theintermediate pipe, then remove the pipe fromunder the vehicle.

Centre silencer10 Slacken the clamping ring bolts anddisengage the clamps from the front and rearflange joints.

Complete system14 Undo the nuts securing the front pipeflange joint to the manifold, and the single boltsecuring the front pipe to its mountingbracket. Separate the flange joint and collectthe gasket. Free the system from all itsmounting rubbers and lower it from under thevehicle.

Heat shield(s)15 The heat shields are secured to theunderside of the body (and on some modelsto the fuel tank) by various nuts and bolts (see illustration). Each shield can beremoved once the relevant exhaust sectionhas been removed. If a shield is being

removed to gain access to a componentlocated behind it, it may prove sufficient insome cases to remove the retaining nutsand/or bolts, and simply lower the shield,without disturbing the exhaust system.

Refitting16 Each section is refitted by reversing theremoval sequence, noting the following:a) Ensure that all traces of corrosion have

been removed from the flanges andrenew all necessary gaskets.

b) Inspect the rubber mountings for signs ofdamage or deterioration, and renew asnecessary.

c) Prior to assembling the spring-loadedjoint, a smear of high-temperature greaseshould be applied to the joint matingsurfaces.

d) Where joints are secured together by aclamping ring, apply a smear of exhaustsystem jointing paste to the flange joint,to ensure a gas-tight seal. Tighten theclamping ring nuts evenly andprogressively to the specified torquesetting, so that the clearance between theclamp halves remains equal on eitherside.

e) Prior to tightening the exhaust systemfasteners, ensure that all rubbermountings are correctly located, and thatthere is adequate clearance between theexhaust system and vehicle underbody.Move the system side-to-side, and up-and-down, to ensure it will not hitanything when the car is moving.

1 General information andprecautions

The fuel system consists of a fuel tank(which is mounted under the rear of the car,with an electric fuel pump immersed in it), afuel filter, fuel feed and return lines, and thethrottle body assembly (which incorporatesthe single fuel injector and the fuel pressureregulator). In addition, there is an ElectronicControl Unit (ECU) and various sensors,electrical components and related wiring. Theair cleaner contains a disposable paper filterelement, and incorporates a flap valve airtemperature control system. This allows coldair from the outside of the car and warm airfrom around the exhaust manifold to enter theair cleaner in the correct proportions.

Refer to Section 7 for further information onthe operation of each fuel injection system,and to Section 18 for information on theexhaust system.

Throughout Part B, it is occasionallynecessary to identify vehicles by their enginecodes rather than by engine capacity. Refer tothe relevant Part of Chapter 2 for furtherinformation on engine code identification.

Note: Residual pressure will remain in thefuel lines long after the vehicle was last used.When disconnecting any fuel line, firstdepressurise the fuel system as described inSection 8.

6 Unleaded petrol - generalinformation and usage

Note: The information given in this Chapter iscorrect at the time of writing. If updatedinformation is thought to be required, checkwith a Peugeot dealer. If travelling abroad,consult one of the motoring organisations (or asimilar authority) for advice on the fuelavailable.

The fuel recommended by Peugeot is givenin the Specifications Section of this Chapter,followed by the equivalent petrol currently onsale in the UK.

All Peugeot 405 single-point injectionmodels are designed to run on fuel with aminimum octane rating of 95 (RON). Allmodels are equipped with catalyticconverters, and therefore must be run onunleaded fuel only. Under no circumstancesshould leaded (UK “4-star”) fuel be used, asthis may damage the catalytic converter.

Super unleaded petrol (98 octane) can alsobe used in all models if wished, though thereis no advantage in doing so.

7 Fuel injection systems -general information

Note: The fuel injection ECU is of the “self-learning” type, meaning that as it operates, italso monitors and stores the settings whichgive optimum engine performance under alloperating conditions. When the battery isdisconnected, these settings are lost and theECU reverts to the base settings programmedinto its memory at the factory. On restarting,this may lead to the engine running/idlingroughly for a short while, until the ECU has re-learned the optimum settings. This process isbest accomplished by taking the vehicle on aroad test (for approximately 15 minutes),covering all engine speeds and loads,concentrating mainly in the 2500 to 3500 rpmregion.

Fenix 1B system1 The Fenix 1B system is an integratedsingle-point fuel injection/ignition system.Using inputs from various sensors, theelectronic control unit computes the optimumfuel injector pulse duration, and ignitionadvance setting, to suit the prevailing engineoperating conditions.2 The electronic control unit receives signalsfrom the following sensors.a) Engine speed/position sensor.b) Manifold absolute pressure (MAP) sensor.c) Inlet air temperature sensor.d) Throttle position sensor.e) Coolant temperature sensor.f) Oxygen sensor.

3 The fuel injection unit houses the fuelinjector, the fuel pressure regulator, thethrottle position switch, and the idle speedcontrol valve. The single fuel injector injectsfuel upstream of the throttle valve.4 Idle speed is controlled by the electroniccontrol unit, via the idle speed control valve.5 The oxygen sensor allows the electroniccontrol unit to control the air/fuel mixturewithin very fine limits, to enable the use of acatalytic converter.6 All the information supplied to theelectronic control unit is computed andcompared with pre-set values stored in the

4.3 Adjust the accelerator cable asdescribed in text

Warning: Many of theprocedures in this Chapterrequire the removal of fuel linesand connections, which may

result in some fuel spillage. Beforecarrying out any operation on the fuelsystem, refer to the precautions given in“Safety first!” at the beginning of thismanual, and follow them implicitly. Petrolis a highly dangerous and volatile liquid,and the precautions necessary whenhandling it cannot be overstressed.

module memory, to determine the requiredperiod of injection.7 The electronic control unit constantly variesthe fuel mixture, engine idle speed, andignition timing to provide optimum engineefficiency under all operating conditions, andto reduce exhaust gas emissions. The mixturestrength is accurately controlled to maintain itwithin the operating limits of the catalyticconverter.

Bosch Monopoint MA3.0 system8 The Bosch Monopoint MA3.0 enginemanagement (fuel injection/ignition) systemincorporates a closed-loop catalytic converterand an evaporative emission control system,and complies with the latest emission controlstandards. The system operates as follows.9 The fuel pump, immersed in the fuel tank,pumps fuel from the fuel tank to the fuelinjector, via a filter mounted underneath therear of the vehicle. Fuel supply pressure iscontrolled by the pressure regulator in thethrottle body assembly. The regulatoroperates by allowing excess fuel to return tothe tank.10 The electrical control system consists ofthe ECU, along with the following sensors.

a) Throttle potentiometer - informs the ECUof the throttle position, and the rate ofthrottle opening or closing.

b) Coolant temperature sensor - informs theECU of engine temperature.

c) Inlet air temperature sensor - informs theECU of the temperature of the air passingthrough the throttle body.

d) Lambda sensor - informs the ECU of theoxygen content of the exhaust gases(explained in Part D of this Chapter).

e) Microswitch (built into the idle speedstepper motor) - informs the ECU whenthe throttle valve is closed (ie when theaccelerator pedal is released).

f) Crankshaft sensor - informs the ECU ofengine speed and crankshaft position

g) Vehicle speed sensor (fitted to thegearbox) - informs the ECU of road speed.

11 All the above information is analysed bythe ECU and, based on this, the ECUdetermines the appropriate ignition andfuelling requirements for the engine. The ECUcontrols the fuel injector by varying its pulsewidth - the length of time the injector is heldopen - to provide a richer or weaker mixture,as appropriate. The mixture is constantlyvaried by the ECU, to provide the best settingfor cranking, starting (with either a hot or coldengine), warm-up, idle, cruising, andacceleration. Refer to Chapter 5 for furtherinformation on the ignition system.12 The ECU also has full control over theengine idle speed, via a stepper motor whichis fitted to the throttle body. The motorpushrod rests against a cam on the throttlevalve spindle. When the throttle valve isclosed, the ECU uses the motor to vary theopening of the throttle valve and so controlsthe idle speed.

13 The ECU also controls the exhaust andevaporative emission control systems, whichare described in Part D of this Chapter.14 If there is an error in any of the readingsobtained from either the coolant temperaturesensor, the inlet air temperature sensor or thelambda sensor, the ECU enters its back-upmode. In this event, the ECU ignores theabnormal sensor signal, and assumes a pre-programmed value which will allow the engineto continue running (albeit at reducedefficiency). If the ECU enters this back-upmode, the warning light on the instrumentpanel will come on, and the relevant faultcode will be stored in the ECU memory.15 If the warning light comes on, the vehicleshould be taken to a Peugeot dealer at theearliest opportunity. A complete test of theengine management system can then becarried out, using a special electronicdiagnostic test unit which is simply pluggedinto the system’s diagnostic connector.

Magneti Marelli G5 and G6 systems16 A Magneti Marelli engine management(fuel injection/ignition) system is fitted to 1580 cc XU5 engines.17 The fuel injection side of the systemoperates as described in the followingparagraphs. Refer to Chapter 5 for informationon the ignition side of the system.18 The fuel pump, immersed in the fuel tank,pumps fuel from the fuel tank to the fuelinjector, via a filter. Fuel supply pressure iscontrolled by the pressure regulator in thethrottle body assembly. The regulatoroperates by allowing excess fuel to return tothe tank. To reduce emissions and to improvedriveability when the engine is cold, enginecoolant is passed through the manifold andaround the throttle body assembly.19 The electrical control system consists ofthe ECU, along with the following sensors.

a) Manifold absolute pressure (MAP) sensor- informs the ECU of the load on theengine (expressed in terms of inletmanifold vacuum).

b) Crankshaft sensor - informs the ECU ofthe crankshaft position and engine speed.

c) Throttle potentiometer - informs the ECUof the throttle position, and the rate ofthrottle opening/closing.

d) Coolant temperature sensor - informs theECU of the engine temperature.

e) Fuel/air mixture temperature sensor -informs the ECU of the fuel/air mixturecharge temperature entering the engine.

f) Lambda (oxygen) sensor - informs theECU of the oxygen content of the exhaustgases (explained in greater detail in Part Dof this Chapter).

20 In addition, the ECU senses batteryvoltage (adjusting the injector pulse width tosuit, and using the stepper motor to increasethe idle speed and, therefore, the alternatoroutput if the voltage is too low). Short-circuitprotection and diagnostic capabilities are

incorporated into the ECU, and it can bothreceive and transmit information via theengine management circuit diagnosticconnector, thus permitting engine diagnosisand tuning by special diagnostic equipment.21 All the above signals are compared by theECU, using digital techniques, with set valuespre-programmed (mapped) into its memory.Based on this information, the ECU selectsthe response appropriate to those values andcontrols the ignition HT coil (see Chapter 5),and the fuel injector (varying its pulse width -the length of time the injector is held open - toprovide a richer or weaker mixture, asappropriate). The mixture, idle speed andignition timing are constantly varied by theECU, to provide the best settings for cranking,starting (with either a hot or cold engine),warm-up, idle, cruising and acceleration.22 The ECU regulates the engine idle speedvia a stepper motor which is fitted to thethrottle body. The motor has a pushrodcontrolling the opening of an air passagewhich bypasses the throttle valve. When thethrottle valve is closed, the ECU controls themovement of the motor pushrod, whichregulates the amount of air which flowsthrough the throttle body passage, and socontrols the idle speed. The bypass passageis also used as an additional air supply duringcold starting.23 The ECU also controls the exhaust andevaporative emission control systems, whichare described in Part D of this Chapter.24 If there is an error in any of the readingsobtained from any of the engine managementcircuit sensors, the ECU enters its back-upmode. In this event, the ECU ignores theabnormal sensor signal, and assumes a pre-programmed value which will allow the engineto continue running (albeit at reducedefficiency). On entering this back-up mode,the engine management warning light in theinstrument panel will come on, informing thedriver of the fault, and the relevant fault codewill be stored in the ECU memory.25 If the warning light comes on, the vehicleshould be taken to a Peugeot dealer at theearliest opportunity. A complete test of theengine management system can then becarried out, using a special electronicdiagnostic test unit which is simply pluggedinto the system’s diagnostic connector.

8 Fuel injection system -depressurisation 2

Note: Refer to the warning note in Section 1before proceeding.

Fuel/exhaust systems - single-point fuel injection models 4B•3

Warning: The followingprocedure will merely relievethe pressure in the fuel system -remember that fuel will still be

present in the system components, andtake precautions accordingly beforedisconnecting any of them.

1 The fuel system referred to in this Section isdefined as the tank-mounted fuel pump, thefuel filter, the fuel injector and the pressureregulator in the injector housing, and themetal pipes and flexible hoses of the fuel linesbetween these components. All these containfuel which will be under pressure while theengine is running, and/or while the ignition isswitched on. The pressure will remain forsome time after the ignition has beenswitched off, and it must be relieved in acontrolled fashion when any of thesecomponents are disturbed for servicing work.2 Disconnect the battery negative terminal.3 Place a suitable container beneath theconnection or union to be disconnected, andhave a large rag ready to soak up anyescaping fuel not being caught by thecontainer.4 Slowly loosen the connection or union nutto avoid a sudden release of pressure, andposition the rag around the connection, tocatch any fuel spray which may be expelled.Once the pressure is released, disconnect thefuel line. Plug the pipe ends, to minimise fuelloss and prevent the entry of dirt into the fuelsystem.5 An alternative method of depressurising thefuel system is to remove either the fuel pumpfuse or the fuel pump relay and start theengine. Allow the engine to idle until it stops.Turn the engine over on the starter once ortwice to ensure that all pressure is released,then switch off the ignition. Always disconnectthe battery negative lead before carrying outwork on the fuel system, and do not forget torefit the fuse or relay when work is complete.

9 Fuel pump - removal and refitting 2

Note: Refer to the warning note in Section 1before proceeding. The fuel pump is mountedeither on the outside of the fuel tank (external)or on the inside of the fuel tank (internal)according to model.

The pump is located under theright-hand cover.9 Disconnect the wiring connector from thefuel pump, and tape the connector to thevehicle body, to prevent it from disappearingbehind the tank (see illustration).10 Mark the hoses for identificationpurposes, then slacken the feed and returnhose retaining clips. Where the crimped-typePeugeot hose clips are fitted, cut the clips anddiscard them; use standard worm-drive hoseclips on refitting. Disconnect both hoses fromthe top of the pump, and plug the hose ends.11 Noting the alignment marks on the tank,pump cover and the locking ring, unscrew thering and remove it from the tank (seeillustration). This is best accomplished byusing a screwdriver on the raised ribs of thelocking ring. Carefully tap the screwdriver to

turn the ring anti-clockwise until it can beunscrewed by hand.12 Displace the pump cover, then reach intothe tank and unclip the pump from the tankbase. Lift the fuel pump assembly out of thefuel tank, taking great care not to damage thefilter, or to spill fuel onto the interior of thevehicle. Recover the rubber sealing ring anddiscard it - a new one must be used onrefitting (see illustrations).13 Note that the fuel pump is only availableas a complete assembly - no components areavailable separately.

RefittingExternal mounted14 Slide the pump into the rubber mountingstraps and secure with a new plastic cable-tie.15 Reconnect the fuel inlet and outlet hoses.16 Reconnect the electrical connections.17 Lower the vehicle to the ground andreconnect the battery negative lead.18 Start the engine and check for leaks.

13 Fuel injection system -testing and adjustment 3

Testing1 If a fault appears in the fuel injectionsystem, first ensure that all the system wiringconnectors are securely connected and freeof corrosion. Ensure that the fault is not due topoor maintenance; ie, check that the aircleaner filter element is clean, the spark plugsare in good condition and correctly gapped,the valve clearances are correctly adjusted,the cylinder compression pressures arecorrect, the ignition timing is correct, and thatthe engine breather hoses are clear andundamaged, referring to Chapters 1, 2 and 5for further information.2 If these checks fail to reveal the cause ofthe problem, the vehicle should be taken to aPeugeot dealer for testing. A wiring blockconnector is incorporated in the enginemanagement circuit, into which a specialelectronic diagnostic tester can be plugged.The connector is clipped to the rear of theECU mounting box. The tester will locate thefault quickly and simply, alleviating the needto test all the system components individually,which is a time-consuming operation that alsocarries a risk of damaging the ECU.

Adjustment3 Experienced home mechanics with aconsiderable amount of skill and equipment(including a tachometer and an accuratelycalibrated exhaust gas analyser) may be ableto check the exhaust CO level and the idlespeed. However, if these are found to be inneed of adjustment, the car must be taken toa Peugeot dealer for further testing.4 On the Fenix and Bosch systems, noadjustment is possible. Should the idle speedor exhaust gas CO level be incorrect, then afault must be present in the fuel injectionsystem.5 On the Magneti Marelli system, it ispossible to adjust the mixture setting (exhaustgas CO level) and ignition timing. However,adjustments can be made only by re-programming the ECU, using specialdiagnostic equipment connected to thesystem via the diagnostic connector.

1 General information andprecautions

The fuel supply system consists of a fueltank (mounted under the rear of the car), withan electric fuel pump either mountedexternally or internally in the tank, a fuel filter,fuel feed and return lines. The fuel pumpsupplies fuel to the fuel rail, which acts as areservoir for the four fuel injectors which injectfuel into the inlet tracts. The fuel filterincorporated in the feed line from the pump tothe fuel rail ensures that the fuel supplied tothe injectors is clean.

Refer to Section 6 for further information onthe operation of each fuel injection system,and to Section 21 for information on theexhaust system. Throughout this Section, it isalso occasionally necessary to identifyvehicles by their engine codes rather than byengine capacity alone. Refer to the relevantPart of Chapter 2 for further information onengine code identification.

Note: Residual pressure will remain in thefuel lines long after the vehicle was last used.When disconnecting any fuel line, firstdepressurise the fuel system as described inSection 7.

Note: At the time of writing little informationwas available for the Sagem-Lucas injectionsystem.

4C•2 Fuel/exhaust systems - multi-point fuel injection models

Warning: Many of theprocedures in this Chapterrequire the removal of fuel linesand connections, which may

result in some fuel spillage. Beforecarrying out any operation on the fuelsystem, refer to the precautions given in“Safety first!” at the beginning of thismanual, and follow them implicitly. Petrolis a highly dangerous and volatile liquid,and the precautions necessary whenhandling it cannot be overstressed.

information is thought to be required, checkwith a Peugeot dealer. If travelling abroad,consult one of the motoring organisations (or asimilar authority) for advice on the fuelavailable.

The fuel recommended by Peugeot is givenin the Specifications Section of this Chapter,followed by the equivalent petrol currently onsale in the UK.

All multi-point injection models aredesigned to run on fuel with a minimumoctane rating of 95 (RON). All models with acatalytic converter must be run on unleadedfuel only. Under no circumstances shouldleaded fuel (UK “4-star”) be used, as this maydamage the converter.

6 Fuel injection systems -general information

Note: On later models the fuel injection ECUis of the “self-learning” type, meaning that as itoperates, it also monitors and stores thesettings which give optimum engineperformance under all operating conditions.When the battery is disconnected, thesesettings are lost and the ECU reverts to thebase settings programmed into its memory atthe factory. On restarting, this may lead to theengine running/idling roughly for a short while,until the ECU has re-learned the optimumsettings. This process is best accomplished bytaking the vehicle on a road test (forapproximately 15 minutes), covering all enginespeeds and loads, concentrating mainly in the2500 to 3500 rpm region.

Bosch L3.1 (Jetronic) system1 The Bosch L3.1 fuel injection system is ofthe intermittent type operating under lowpressure. Fuel is drawn from the rear-mounted fuel tank by an externally-mountedfuel pump and delivered through an in-linefilter to the injectors. A pressure regulatormounted on the outlet side of the fuel rail, andconnected by pipe to the inlet manifold tosense vacuum, maintains a constant pressureat the injectors according to the depression inthe inlet manifold, returning excess fuel to thefuel tank.2 A pulse damper on the inlet side of the fuel

rail damps out the pressure pulses caused bythe operation of the injectors.3 The electronic control unit (ECU) andairflow meter are mounted on the air filterhousing. The ECU uses signals from varioussensors to determine the opening period ofthe injectors for any given engine operatingcondition. The inputs are as follows.a) Amount of air being drawn in by the

engine via the airflow meter.b) Inlet air temperature via the thermistor

mounted in the airflow meter.c) Engine speed and angular position via the

injection (coolant) thermistor.d) Throttle position via the throttle switch

unit.4 The injectors operate simultaneously,spraying fuel onto the inlet side of the inletvalves.5 A supplementary air device is fitted to thesystem to compensate for the extra fuelrequired during cold start conditions.

Bosch LU2-Jetronic system6 The principle of operation of the LU2-Jetronic system is similar to that described forthe L3.1-Jetronic system but with thefollowing differences.a) A single-barrel throttle body is fitted.b) An oxygen sensor is fitted.c) A catalytic converter is fitted.

7 The most significant difference is that theLU2-Jetronic system incorporates an oxygensensor in the exhaust system, which enablesthe electronic control unit to carry out finefuel/air mixture adjustment to allow the use ofa catalytic converter.

Bosch Motronic MP3.1 system8 The principle of operation of the MotronicMP3.1 system is similar to that described forthe L3.1-Jetronic system but with thefollowing differences.a) The ECU controls the ignition system in

addition to the fuel injection system,providing an integrated enginemanagement system.

b) A static (distributorless)ignition system isused.

c) An inlet air temperature sensor and amanifold absolute pressure (MAP) sensorare used in place of the airflow meter.

d) An engine speed/position sensor is usedto provide information on engine speedand crankshaft position.

Bosch Motronic M1.3 system9 The principle of operation of the MotronicM1.3 system is similar to that described forthe L3.1-Jetronic system but with thefollowing differences.a) The ECU controls the ignition system and

the fuel injection system, providing anintegrated engine management system.

b) An engine speed/position sensor is usedto provide information on engine speedand crankshaft position.

c) The ECU controls the idle speed under allengine operating conditions, via an idlespeed control valve. No supplementary airdevice is fitted.

d) An oxygen sensor is fitted to enable theECU to control the air/fuel mixture veryaccurately, allowing the use of a catalyticconverter.

e) A knock sensor, mounted in the cylinderblock is used to detect the onset ofengine knock, or pre-ignition. Thisenables the ECU to select the optimumignition advance for the prevailing engineoperating conditions without risk ofdamage to the engine.

Bosch Motronic ML4.1 system10 The principle of operation of the MotronicML4.1 system is similar to that described forthe L3.1-Jetronic system but with thefollowing differences.a) The ECU incorporates a cold start

function and a fault memory.b) The mixture adjustment by-pass screw is

replaced by an adjustment screw on thethrottle potentiometer.

c) The throttle housing has a double body.d) Idle speed is maintained at a

predetermined level (regardless of load)by an idle speed valve.

Bosch Motronic MP5.1 system11 The Bosch Motronic MP5.1 enginemanagement (fuel injection/ignition) systemincorporates a closed-loop catalytic converterand an evaporative emission control system,and complies with the very latest emissioncontrol standards. Refer to Chapter 5 fordetaisl on the ignition side of the system; thefuel side of the system operates as follows.12 The fuel pump (which is immersed in thefuel tank) supplies fuel from the tank to thefuel rail, via a filter mounted underneath therear of the vehicle. Fuel supply pressure iscontrolled by the pressure regulator in the fuelrail. When the optimum operating pressure ofthe fuel system is exceeded, the regulatorallows excess fuel to return to the tank.13 The electrical control system consists ofthe ECU, along with the following sensors:a) Throttle potentiometer - informs the ECU

of the throttle position, and the rate ofthrottle opening/closing.

4C

b) Coolant temperature sensor - informs theECU of engine temperature.

c) Inlet air temperature sensor - informs theECU of the temperature of the air passingthrough the throttle housing.

d) Lambda sensor - informs the ECU of theoxygen content of the exhaust gases(explained in Part D of this Chapter).

e) Crankshaft sensor - informs the ECU ofcrankshaft position and speed of rotation.

f) Manifold Absolute Pressure (MAP) sensor- informs the ECU of the load on theengine (expressed in terms of inletmanifold vacuum).

g) Vehicle speed sensor - informs the ECUof the vehicle speed.

14 All the above signals are analysed by theECU which selects the fuelling responseappropriate to those values. The ECU controlsthe fuel injectors (varying the pulse width - thelength of time the injectors are held open - toprovide a richer or weaker mixture, asappropriate). The mixture is constantly variedby the ECU, to provide the best setting forcranking, starting (with either a hot or coldengine), warm-up, idle, cruising andacceleration.15 The ECU also has full control over theengine idle speed, via an auxiliary air valvewhich bypasses the throttle valve. When thethrottle valve is closed, the ECU controls theopening of the valve, which in turn regulatesthe amount of air entering the manifold, andso controls the idle speed.16 The ECU also controls the exhaust andevaporative emission control systems, whichare described in Part D of this Chapter.17 An electric heating element is fitted to thethrottle housing; the heater is supplied withcurrent by the ECU, and warms the throttlehousing on cold starts to prevent possibleicing of the throttle valve.18 If there is an abnormality in any of thereadings obtained from either the coolanttemperature sensor, the inlet air temperaturesensor or the lambda sensor, the ECU entersits back-up mode. In this event, it ignores theabnormal sensor signal and assumes a pre-programmed value which will allow the engineto continue running (albeit at reducedefficiency). If the ECU enters this back-upmode, the warning light on the instrumentpanel will come on, and the relevant faultcode will be stored in the ECU memory.19 If the warning light comes on, the vehicleshould be taken to a Peugeot dealer at theearliest opportunity. A complete test of theengine management system can then becarried out, using a special electronicdiagnostic test unit which is simply pluggedinto the system’s diagnostic connector.

Magneti Marelli 8P system20 The Magneti Marelli 8P enginemanagement (fuel injection/ignition) system isvery similar in operation to the Bosch MP5.1system described above, apart from the idlespeed control system.

21 On the Magneti Marelli system, the idlespeed is controlled by the ECU via a steppermotor fitted to the throttle housing. The motorhas a pushrod controlling the opening of anair passage which bypasses the throttle valve.When the throttle valve is closed, the ECUcontrols the movement of the motor pushrod,which regulates the amount of air which flowsthrough the throttle housing passage, socontrolling the idle speed. The bypasspassage is also used as an additional airsupply during cold starting.

7 Fuel injection system - depressurisation 2

Note: Refer to the warning note in Section 1before proceeding.

1 The fuel system referred to in this Section isdefined as the tank-mounted fuel pump, thefuel filter, the fuel injectors, the fuel rail andthe pressure regulator, and the metal pipesand flexible hoses of the fuel lines betweenthese components. All these contain fuelwhich will be under pressure while the engineis running, and/or while the ignition isswitched on. The pressure will remain forsome time after the ignition has beenswitched off, and must be relieved in acontrolled fashion when any of thesecomponents are disturbed for servicing work.2 Disconnect the battery negative terminal.3 Place a container beneath the connection/union to be disconnected, and have a largerag ready to soak up any escaping fuel notbeing caught by the container.4 Slowly loosen the connection or union nutto avoid a sudden release of pressure, andwrap the rag around the connection, to catchany fuel spray. Once the pressure is released,disconnect the fuel line. Plug the pipe ends, tominimise fuel loss and prevent the entry of dirtinto the fuel system.

8 Fuel pump - removal and refitting 3

Refer to Chapter 4B, Section 9.

9 Fuel gauge sender unit -removal and refitting 3

Refer to Chapter 4A, Section 5. Where thefuel pump is mounted externally there are nofuel pipe connections to the sender unit.

10 Fuel tank - removal and refitting 3

Refer to Chapter 4A, Section 6, noting thatit will be necessary to depressurise the fuelsystem before the feed and return hoses aredisconnected (see Section 7). It will also benecessary to disconnect the wiring connectorfrom the internal fuel pump before loweringthe tank out of position.

11 Fuel injection system -testing and adjustment 2

Testing1 If a fault appears in the fuel injectionsystem, first ensure that all the system wiringconnectors are securely connected and freeof corrosion. Ensure that the fault is not due topoor maintenance; ie, check that the aircleaner filter element is clean, the spark plugsare in good condition and correctly gapped,the cylinder compression pressures arecorrect, the ignition timing is correct, and thatthe engine breather hoses are clear andundamaged, referring to Chapters 1, 2 and 5for further information.2 If these checks fail to reveal the cause ofthe problem, the vehicle should be taken to asuitably-equipped Peugeot dealer for testing.On later models a wiring block connector isincorporated in the engine managementcircuit, into which a special electronicdiagnostic tester can be plugged. The testerwill locate the fault quickly and simply,alleviating the need to test all the systemcomponents individually, which is a time-consuming operation that carries a risk ofdamaging the ECU.

Adjustment

Bosch L3.1 and MP3.1 systems3 Before attempting to adjust the idle speedor mixture (CO), ensure that the followingconditions are met.a) Ignition system is in good condition and

correctly adjusted.b) Air filter is clean.c) Throttle initial positions correctly adjusted.d) Throttle switch correctly adjusted.e) Engine must be hot, the cooling fan

having cut in at least once, but the fanmust not be running during the actualadjustment.

4 Idle speed is adjusted using the idle speedadjustment screw on the throttle housing (seeillustration). Turn the screw clockwise todecrease the idle speed, or anti-clockwise toincrease the speed.5 To adjust the idle mixture, prise out thetamperproof cap covering the mixture (CO)adjustment screw on the airflow meter unit.

4C•4 Fuel/exhaust systems - multi-point fuel injection models

Warning: The followingprocedure will merely relievethe pressure in the fuel system -remember that fuel will still be

present in the system components andtake precautions accordingly beforedisconnecting any of them.

6 Connect an exhaust gas analyser to thevehicle in accordance with the manufacturer’sinstructions.7 Start the engine and allow it to idle. Turnthe mixture adjustment screw in or out toobtain the specified CO content (seeillustration).8 Re-adjust the idle speed as previouslydescribed.9 On completion, stop the engine, remove alltest equipment and fit a new tamperproof capto the screw.

Bosch ML4.1 system10 The idle speed is non-adjustable. It iscontrolled by the idle speed regulator valve.11 To check the mixture (CO), first ensurethat the conditions in paragraph 3 are met.12 Connect an exhaust gas analyser to thevehicle in accordance with the manufacturer’sinstructions.13 Remove the tamperproof cap from themixture adjustment screw on the airflow meterhousing.14 Turn the screw clockwise to increase andanti-clockwise to decrease CO content untilthe specified CO level is obtained.15 Remove all test equipment and fit a newtamperproof plug to the screw.

Bosch LU2-Jetronic system16 Idle speed is adjusted as described forthe Bosch L3.1 system (see illustration).

17 Idle mixture is not adjustable, and isautomatically regulated by the electroniccontrol unit according to signals provided bythe oxygen sensor.

Bosch Motronic M1.3 system18 Idle speed is only adjustable on 8-valveengines; on 16-valve engines it is controlledby the ECU. On 8-valve engines use theprocedure given in paragraphs 3 and 4.19 Adjustment of idle mixture is as given inparagraphs 5 to 9.

MM8P, Sagem-Lucas 4GJ, Bosch Motronic 5.1, Bosch Motronic 3.2 systems20 Experienced home mechanics with aconsiderable amount of skill and equipment(including a tachometer and an accuratelycalibrated exhaust gas analyser) may be ableto check the exhaust CO level and the idle

speed. However, if these are found to be inneed of adjustment, the car must be taken toa suitably-equipped Peugeot dealer for furthertesting. Neither the mixture adjustment(exhaust gas CO level) nor the idle speed areadjustable, and should either be incorrect, afault must be present in the fuel injectionsystem.

The carburettor typewill partially obstruct the injector ports causingerratic running and loss of power.

19 ACAV inlet system (16-valvemodels) - general information,removal and refitting

3General information1 To ensure optimum efficiency at highengine speeds, and maximum torque at lowerengine speeds, 16-valve models have an inletmanifold with a variable inlet tract system. Thesystem is called ACAV (variable acousticcharacteristic induction).2 The inlet manifold is divided into two tractsof different length and diameter; a long tract(for low-speed torque) which is 650 mm long,diameter 36 mm, and a short tract (for high-speed power) which is 370 mm long, diameter45 mm.3 Situated between the manifold and thecylinder head is a line of four butterfly valves,mounted in an alloy housing. Mounted oneither end of the housing is a vacuumdiaphragm assembly. Each diaphragm isconnected to the butterfly valve spindles via apushrod. The vacuum diaphragms areconnected to an electrically-operatedsolenoid valve, which is in turn connected tothe braking system vacuum pump. The pumpis mounted on the end of the cylinder head,and is driven off the left-hand end of the inletcamshaft.4 At engine speeds below 1800 rpm andabove 5080 rpm, the ECU closes the solenoidvalve, shutting off the vacuum supply to thediaphragms, and the butterfly valves are

closed. With the valves closed, the short inlettracts are closed, and the incoming air flowsonly through the long inlet tract, boosting thetorque output.5 At engine speeds between 1800 rpm and5080 rpm, the ECU opens the solenoid valve.The vacuum present in the pump is thenallowed to act on the vacuum diaphragms,which draws the pushrods into the diaphragmbodies, and opens up the four butterfly valves.With the valves open, the incoming air isallowed to flow through both the short andlong inlet tracts, for maximum power.6 To check the system, start the engine andallow it to idle. Slowly increase the enginespeed, whilst observing the vacuumdiaphragm pushrods. At approximately 1800rpm, the pushrods should be drawn into thediaphragm bodies (valves open). Release thethrottle cam, and allow the engine to idleagain; the pushrods should extend from thediaphragms (valves closed).7 To check the operation of the solenoidvalve, disconnect the vacuum pipe from thediaphragm. Start the engine, and allow it toidle. Place your finger over the end of thepipe; no vacuum should be present in thepipe. Slowly increase the engine speed; atapproximately 1800 rpm, vacuum should befelt in the pipe. Allow the engine to idle again,and check that the vacuum supply is switchedoff. If this is not the case, either the solenoidvalve or its supply voltage is at fault.8 To check the operation of either vacuumdiaphragm assembly, disconnect the vacuumpipe, and suck hard at the control valve stub;the pushrod should be drawn into thediaphragm body, and the valve should open.If this is not the case, the vacuum diaphragmis faulty.

Removal and refitting

ACAV valve assembly9 Remove the inlet manifold as described inSection 18.10 Bearing in mind the information given inSection 7, slacken the retaining clip, anddisconnect the fuel feed and return hosesfrom their unions on the fuel rail.

1 General information

1 All models have various built-in fuel systemfeatures which help to minimise emissions,and all models have at least the crankcaseemission-control system described below.Models with a catalytic converter are alsofitted with the exhaust and evaporativeemission control systems.2 Most models are able to run on 95 RONunleaded fuel, but the following early enginesmust use 97 RON leaded fuel. However it maybe possible to use unleaded fuel if the ignitionis retarded by 3° - check with your Peugeotdealer.a) TU3 (K1A)b) TU3A (K1G)c) XU92C (D2D)d) XU9J2 (D6A)e) XU9J4 (D6C)f) XU52C (B2A)

Crankcase emission control3 To reduce the emission of unburnedhydrocarbons from the crankcase into theatmosphere, the engine is sealed, and theblow-by gases and oil vapour are drawn fromthe crankcase, through a wire-mesh oilseparator, into the inlet tract, to be burned bythe engine during normal combustion.4 Under conditions of high manifolddepression (idling, deceleration) the gases willbe sucked positively out of the crankcase.Under conditions of low manifold depression(acceleration, full-throttle running) the gasesare forced out of the crankcase by the(relatively) higher crankcase pressure; if theengine is worn, the raised crankcase pressure(due to increased blow-by) will cause some ofthe flow to return under all manifoldconditions.

Exhaust emission control5 To minimise the amount of pollutants whichescape into the atmosphere, some models

are fitted with a catalytic converter in theexhaust system. On all models where acatalytic converter is fitted, the system is ofthe “closed-loop” type; a lambda (oxygen)sensor in the exhaust system provides the fuelinjection/ignition system ECU with constantfeedback, enabling the ECU to adjust themixture to provide the best possibleconditions for the converter to operate.6 The lambda sensor has a built-in heatingelement, controlled by the ECU through thelambda sensor relay, to quickly bring thesensor’s tip to an efficient operatingtemperature. The sensor’s tip is sensitive tooxygen, and sends the ECU a varying voltagedepending on the amount of oxygen in theexhaust gases. If the inlet air/fuel mixture istoo rich, the exhaust gases are low in oxygen,so the sensor sends a low-voltage signal. Thevoltage rises as the mixture weakens and theamount of oxygen in the exhaust gases rises.Peak conversion efficiency of all majorpollutants occurs if the inlet air/fuel mixture ismaintained at the chemically-correct ratio forthe complete combustion of petrol - 14.7parts (by weight) of air to 1 part of fuel (the

“stoichiometric” ratio). The sensor outputvoltage alters in a large step at this point, theECU using the signal change as a referencepoint, and correcting the inlet air/fuel mixtureaccordingly by altering the fuel injector pulsewidth (the length of time that the injector isopen).

Evaporative emission control7 To minimise the escape into theatmosphere of unburned hydrocarbons, anevaporative emissions control system is fittedto later models (see illustration). The fueltank filler cap is sealed, and a charcoalcanister, mounted underneath the front left-hand wing, collects the petrol vapoursgenerated in the tank when the car is parked.The canister stores them until they can becleared from the canister (under the control ofthe fuel injection/ignition system ECU) via thepurge solenoid valve. When the valve isopened, the fuel vapours pass into the inlettract, to be burned by the engine duringnormal combustion.8 To ensure that the engine runs correctlywhen it is cold and/or idling, the ECU does not

open the purge control valve until the enginehas warmed up and is under load; the valvesolenoid is then modulated on and off, toallow the stored vapour to pass into the inlettract.

Remove the left-hand front wheel.4 Remove the left-hand front wheel arch linerwith reference to Chapter 11.5 Disconnect the hoses from the canister,noting their locations to ensure correctrefitting.6 Unscrew the clamp bolt, and lift thecanister from its clamp on the body panel.Alternatively, the complete clampbracket/canister assembly can be removed ifdesired. Store or dispose of the canistercarefully - it may contain fuel vapour.7 Refitting is a reversal of removal, but ensurethat the hoses are correctly reconnected asnoted before removal.

Purge valve(solenoid valve) - renewal8 The purge valve is located in the hoserunning from the carbon canister to thethrottle body/inlet manifold. The valve may bemounted on a bracket, or may simply beattached to the hoses, depending on model.

9 To remove the valve, first disconnect thebattery negative lead.10 Where applicable, unbolt the valvebracket, then disconnect the wiring plug.11 Disconnect the hoses from the valve,noting their locations to ensure correctrefitting, then withdraw the valve.12 Refitting is a reversal of removal, ensuringthat the hoses are correctly reconnected, asnoted before removal.

Exhaust emission control

Testing13 The performance of the catalyticconverter can be checked only by measuringthe idle mixture setting (exhaust gas COcontent) using an accurately calibratedexhaust gas analyser.14 If the CO level at the tailpipe is too high,the vehicle should be taken to a Peugeotdealer so that the complete fuel injection andignition systems, including the lambda sensor,can be thoroughly checked using the specialdiagnostic equipment.15 Once this has been done, any fault mustlie in the catalytic converter, which should berenewed as described below.

Catalytic converter - renewal16 Refer to Part A of this Chapter, for thecentre silencer.

Lambda sensor - renewalNote: The lambda sensor is fragile, and willnot work if it is dropped or knocked, if itspower supply is disrupted, or if any cleaningmaterials are used on it.17 According to model the Lambda sensor islocated either in the exhaust downpipe or inthe exhaust centre section.18 Where necessary, jack up the front of thecar and support on axle stands (see “Jackingand Vehicle Support”).19 Trace the wiring back from the lambdasensor to the connector and disconnect it.20 Unscrew the sensor and remove it alongwith its sealing washer.21 Refitting is a reversal of the removalprocedure, using a new sealing washer.Ensure that the sensor is securely tightened.Check that the wiring is correctly routed, andin no danger of contacting either the exhaustsystem or the engine.

3 Catalytic converter - generalinformation and precautions

The catalytic converter is a reliable andsimple device, which needs no maintenancein itself, but there are some facts of which anowner should be aware, if the converter is tofunction properly for its full service life.a) DO NOT use leaded petrol in a car

equipped with a catalytic converter - thelead will coat the precious metals,reducing their converting efficiency, andwill eventually destroy the converter.

b) Always keep the ignition and fuel systemswell-maintained in accordance with themanufacturer’s schedule.

c) If the engine develops a misfire, do notdrive the car at all (or at least as little aspossible) until the fault is cured.

d) DO NOT push- or tow-start the car - thiswill soak the catalytic converter inunburned fuel, causing it to overheatwhen the engine does start.

e) DO NOT switch off the ignition at highengine speeds.

f) DO NOT use fuel or engine oil additives -these may contain substances harmful tothe catalytic converter.

g) DO NOT continue to use the car if theengine burns oil to the extent of leaving avisible trail of blue smoke.

h) Remember that the catalytic converteroperates at very high temperatures. DONOT, therefore, park the car in dryundergrowth, or over long grass or pilesof dead leaves after a long run.

i) Remember that the catalytic converter isFRAGILE - do not strike it with toolsduring servicing work.

j) In some cases, a sulphurous smell (likethat of rotten eggs) may be noticed fromthe exhaust. This is common to manycatalytic converter-equipped cars, andonce the car has covered a few thousandmiles the problem should disappear.

k) The catalytic converter, used on a well-maintained and well-driven car, shouldlast for between 50 000 and 100 000miles - if the converter is no longereffective, it must be renewed.

1 General information andprecautions

General informationThe engine electrical system consists

mainly of the charging and starting systems.Because of their engine-related functions,these components are covered separatelyfrom the body electrical devices such as thelights, instruments, etc (which are covered inChapter 12). Refer to Part B for information onthe ignition system.

The electrical system is of the 12-voltnegative earth type.

The battery is of the low maintenance or“maintenance-free” (sealed for life) type and ischarged by the alternator, which is belt-drivenfrom the crankshaft pulley.

The starter motor is of the pre-engagedtype incorporating an integral solenoid. On

starting, the solenoid moves the drive pinioninto engagement with the flywheel ring gearbefore the starter motor is energised. Oncethe engine has started, a one-way clutchprevents the motor armature being driven bythe engine until the pinion disengages fromthe flywheel.

PrecautionsFurther details of the various systems are

given in the relevant Sections of this Chapter.While some repair procedures are given, theusual course of action is to renew thecomponent concerned. The owner whoseinterest extends beyond component renewalshould obtain a copy of the “AutomobileElectrical & Electronic Systems Manual”,available from the publishers of this manual.

It is necessary to take extra care whenworking on the electrical system to avoiddamage to semi-conductor devices (diodesand transistors), and to avoid the risk ofpersonal injury. In addition to the precautions

given in “Safety first!” at the beginning of thismanual, observe the following when workingon the system:

Always remove rings, watches, etc beforeworking on the electrical system. Even withthe battery disconnected, capacitivedischarge could occur if a component’s liveterminal is earthed through a metal object.This could cause a shock or nasty burn.

Do not reverse the battery connections.Components such as the alternator,electronic control units, or any othercomponents having semi-conductor circuitrycould be irreparably damaged.

If the engine is being started using jumpleads and a slave battery, connect thebatteries positive-to-positive and negative-to-negative (see “Roadside Repairs - jumpstarting”). This also applies when connectinga battery charger.

Never disconnect the battery terminals,the alternator, any electrical wiring or anytest instruments when the engine is running.

Do not allow the engine to turn thealternator when the alternator is notconnected.

Never “test” for alternator output by“flashing” the output lead to earth.

Never use an ohmmeter of the typeincorporating a hand-cranked generator forcircuit or continuity testing.

Always ensure that the battery negativelead is disconnected when working on theelectrical system.

Before using electric-arc weldingequipment on the car, disconnect thebattery, alternator and components such asthe fuel injection/ignition electronic controlunit to protect them from the risk of damage.

The radio/cassette unit fitted as standardequipment by Peugeot is equipped with abuilt-in security code to deter thieves. If thepower source to the unit is cut, the anti-theftsystem will activate. Even if the powersource is immediately reconnected, theradio/ cassette unit will not function until thecorrect security code has been entered.Therefore, if you do not know the correctsecurity code for the radio/cassette unit donot disconnect the battery negative terminalof the battery or remove the radio/cassetteunit from the vehicle. If a Peugeotradio/cassette unit is fitted, refer to“Radio/cassette unit anti-theft system -precaution” in the reference section at therear of this manual.

2 Electrical fault-finding -general information

Refer to Chapter 12.

3 Battery - testing and charging 1Standard and low maintenancebattery - testing1 If the vehicle covers a small annual mileage,it is worthwhile checking the specific gravityof the electrolyte every three months todetermine the state of charge of the battery.Use a hydrometer to make the check andcompare the results with the following table.The temperatures quoted in the table areambient (air) temperatures. Note that thespecific gravity readings assume anelectrolyte temperature of 15°C (60°F); forevery 10°C (50°F) below 15°C (60°F) subtract0.007. For every 10°C (50°F) above 15°C(60°F) add 0.007.

Above Below 25°C(77°F) 25°C(77°F)

Fully-charged 1.210 to 1.230 1.270 to 1.29070% charged 1.170 to 1.190 1.230 to 1.250Discharged 1.050 to 1.070 1.110 to 1.130

2 If the battery condition is suspect, first

check the specific gravity of electrolyte ineach cell. A variation of 0.040 or morebetween any cells indicates loss of electrolyteor deterioration of the internal plates.3 If the specific gravity variation is 0.040 ormore, the battery should be renewed. If thecell variation is satisfactory but the battery isdischarged, it should be charged asdescribed later in this Section.

Maintenance-free battery - testing4 In cases where a “sealed for life”maintenance-free battery is fitted, topping-upand testing of the electrolyte in each cell is notpossible. The condition of the battery cantherefore only be tested using a batterycondition indicator or a voltmeter.5 Certain models may be fitted with a “Delco”type maintenance-free battery, with a built-incharge condition indicator. The indicator islocated in the top of the battery casing, andindicates the condition of the battery from itscolour. If the indicator shows green, then thebattery is in a good state of charge. If theindicator turns darker, eventually to black,then the battery requires charging, asdescribed later in this Section. If the indicatorshows clear/yellow, then the electrolyte levelin the battery is too low to allow further use,and the battery should be renewed. Do notattempt to charge, load or jump start a batterywhen the indicator shows clear/yellow.6 If testing the battery using a voltmeter,connect the voltmeter across the battery andcompare the result with those given in theSpecifications under “charge condition”. Thetest is only accurate if the battery has notbeen subjected to any kind of charge for theprevious six hours. If this is not the case,switch on the headlights for 30 seconds, thenwait four to five minutes before testing thebattery after switching off the headlights. Allother electrical circuits must be switched off,so check that the doors and tailgate are fullyshut when making the test.7 If the voltage reading is less than 12.2 volts,then the battery is discharged, whilst areading of 12.2 to 12.4 volts indicates apartially discharged condition.8 If the battery is to be charged, remove itfrom the vehicle (Section 4) and charge it asdescribed later in this Section.

Standard and low maintenancebattery - chargingNote: The following is a guide only. Alwaysrefer to the manufacturer’s recommendations(often printed on a label attached to thebattery) before charging a battery.9 Charge the battery at a rate of 3.5 to 4amps and continue to charge the battery atthis rate unt il no further rise in specific gravityis noted over a four hour period.10 Alternatively, a trickle charger charging atthe rate of 1.5 amps can safely be usedovernight.11 Specially rapid “boost” chargers whichclaim to restore the battery in 1 to 2 hours are

not recommended, as they can cause damageto the battery plates through overheating.12 While charging the battery, note that thetemperature of the electrolyte should neverexceed 37.8°C (100°F).

Maintenance-free battery - chargingNote: The following is a guide only. Alwaysrefer to the manufacturer’s recommendations(often printed on a label attached to thebattery) before charging a battery.13 This battery type takes considerablylonger to fully recharge than the standardtype, the time taken being dependent on theextent of discharge, but it can take anythingup to three days.14 A constant voltage type charger isrequired, to be set, when connected, to 13.9to 14.9 volts with a charger current below 25amps. Using this method, the battery shouldbe usable within three hours, giving a voltagereading of 12.5 volts, but this is for a partiallydischarged battery and, as mentioned, fullcharging can take considerably longer.15 If the battery is to be charged from a fullydischarged state (condition reading less than12.2 volts), have it recharged by your Peugeotdealer or local automotive electrician, as thecharge rate is higher and constant supervisionduring charging is necessary.

4 Battery - removal and refitting 1Note: On models with a Peugeot anti-theftalarm system, disable the alarm beforedisconnecting the battery (see Chapter 12). Ifa Peugeot radio/cassette unit is fitted, refer to“Radio/cassette unit anti-theft system -precaution”.

Removal1 The battery is located at the right-hand rearcorner of the engine compartment.2 Disconnect the battery terminals, negativeterminal first, by unscrewing the wing nuts orclamp bolts. The negative terminal mustalways be disconnected first, andreconnected last (see illustration).

3 Unscrew the nuts and remove the batteryclamp.4 Lift the battery from the battery tray. Notethe fuel damper bracket on fuel injectionmodels and the fuel pipes on carburettormodels.5 If necessary, release the wiring clips andunbolt the battery tray from the enginecompartment.

Refitting6 Refitting is a reversal of removal, but smearpetroleum jelly on the terminals whenreconnecting the leads, and always reconnectthe positive lead first, and the negative leadlast.

5 Charging system - testing 2Note: Refer to the warnings given in “Safetyfirst!” and in Section 1 of this Chapter beforestarting work.1 If the ignition warning light fails to illuminatewhen the ignition is switched on, first checkthe alternator wiring connections for security.If satisfactory, check that the warning lightbulb has not blown, and that the bulbholder issecure in its location in the instrument panel.If the light still fails to illuminate, check thecontinuity of the warning light feed wire fromthe alternator to the bulbholder. If all issatisfactory, the alternator is at fault, andshould be renewed or taken to an auto-electrician for testing and repair.2 If the ignition warning light illuminates whenthe engine is running, stop the engine andcheck that the drivebelt is correctly tensioned(see Chapter 1) and that the alternatorconnections are secure. If all is so farsatisfactory, have the alternator checked byan auto-electrician for testing and repair.3 If the alternator output is suspect eventhough the warning light functions correctly,the regulated voltage may be checked asfollows.4 Connect a voltmeter across the batteryterminals, and start the engine.5 Increase the engine speed until thevoltmeter reading remains steady; the reading

should be approximately 12 to 13 volts, andno more than 14 volts.6 Switch on as many electrical accessories(eg, the headlights, heated rear window andheater blower) as possible, and check that thealternator maintains the regulated voltage ataround 13 to 14 volts.7 If the regulated voltage is not as stated, thefault may be due to worn brushes, weak brushsprings, a faulty voltage regulator, a faultydiode, a severed phase winding, or worn ordamaged slip rings. The alternator should berenewed or taken to an auto-electrician fortesting and repair.

6 Alternator drivebelt -removal, refitting andtensioning

2Refer to the procedure given for the

auxiliary drivebelt in Chapter 1.

7 Alternator -removal and refitting 3

Removal1 Disconnect the battery negative lead.2 Disconnect the electrical connections onthe rear of the alternator (see illustration).3 Loosen the alternator mounting andadjustment strap bolts, push the alternatorinward and slip the drivebelt off the pulley.4 Remove the adjustment strap bolts andalternator pivot bolts and lift off the alternator(see illustrations).

Refitting5 Refit in reverse order, tensioning the belt asdescribed in Section 6.

8 Alternator -testing and overhaul 2

If the alternator is thought to be suspect, itshould be removed from the vehicle and takento an auto-electrician for testing. Most auto-

electricians will be able to supply and fitbrushes at a reasonable cost. However, checkon the cost of repairs before proceeding as itmay prove more economical to obtain a newor exchange motor.

9 Starting system - testing 2Note: Refer to the precautions given in“Safety first!” and in Section 1 of this Chapterbefore starting work.1 If the starter motor fails to operate when theignition key is turned to the appropriateposition, the following possible causes maybe to blame.a) The battery is faulty.b) The electrical connections between the

switch, solenoid, battery and startermotor are somewhere failing to pass thenecessary current from the batterythrough the starter to earth.

c) The solenoid is faulty.d) The starter motor is mechanically or

electrically defective.2 To check the battery, switch on theheadlights. If they dim after a few seconds,this indicates that the battery is discharged -recharge (see Section 3) or renew the battery.If the headlights glow brightly, operate theignition switch and observe the lights. If theydim, then this indicates that current isreaching the starter motor - therefore, the faultmust lie in the starter motor. If the lightscontinue to glow brightly (and no clickingsound can be heard from the starter motorsolenoid), this indicates that there is a fault inthe circuit or solenoid - refer to the followingparagraphs. If the starter motor turns slowlywhen operated, but the battery is in goodcondition, then this indicates that either thestarter motor is faulty, or there is considerableresistance somewhere in the circuit.3 If a fault in the circuit is suspected,disconnect the battery leads (including theearth connection to the body), the starter/solenoid wiring, and the engine/transmissionearth strap. Thoroughly clean the connections,reconnect the leads and wiring, then use avoltmeter or test light to check that full battery

voltage is available at the battery positive leadconnection to the solenoid, and that the earthis sound. Smear petroleum jelly around thebattery terminals to prevent corrosion -corroded connections are among the mostfrequent causes of electrical system faults.4 If the battery and all connections are ingood condition, check the circuit bydisconnecting the wire from the solenoidblade terminal. Connect a voltmeter or testlight between the wire end and a good earth(such as the battery negative terminal), andcheck that the wire is live when the ignitionswitch is turned to the “start” position. If it is,then the circuit is sound - if not, the circuitwiring can be checked as described inChapter 12.5 The solenoid contacts can be checked byconnecting a voltmeter or test light betweenthe battery positive feed connection on thestarter side of the solenoid, and earth. Whenthe ignition switch is turned to the “start”position, there should be a reading or lightedbulb, as applicable. If there is no reading orlighted bulb, the solenoid is faulty, and shouldbe renewed.6 If the circuit and solenoid are provedsound, the fault must lie in the starter motor.In this event, it may be possible to have thestarter motor overhauled by a specialist, butcheck on the cost of spares beforeproceeding, as it may prove more economicalto obtain a new or exchange motor.

10 Starter motor -removal and refitting 3

Removal1 Disconnect the battery negative lead.2 Disconnect the electrical connections to thestarter motor (see illustration).3 Where necessary, loosen the bolts securingthe rear support bracket to the cylinder block(see illustration).4 Where necessary, unscrew the nutssecuring the rear of the starter motor to thesupport bracket.5 Remove the bolts securing the starter

motor to the gearbox housing (seeillustration). Note the location of any bracketsto ensure correct refitting.6 Unclip the crankcase breather hose fromthe bracket.7 Swing the bracket rearward, thenmanoeuvre the starter motor from the engine.

Refitting8 Refitting is a reversal of the removalprocedure.

11 Starter motor -testing and overhaul 2

If the starter motor is thought to be suspect,it should be removed from the vehicle andtaken to an auto-electrician for testing. Mostauto-electricians will be able to supply and fitbrushes at a reasonable cost. However, checkon the cost of repairs before proceeding as itmay prove more economical to obtain a newor exchange motor.

12 Ignition switch -removal and refitting 2

The ignition switch is integral with thesteering column lock, and can be removedwith reference to Chapter 10.

13 Oil pressure warning lightswitch - removal and refitting 2

Removal1 The switch is located at the front of thecylinder block, above the oil filter mounting.Note that on some models access to theswitch may be improved if the vehicle isjacked up and supported on axle stands sothat the switch can be reached fromunderneath (see “Jacking and VehicleSupport”).2 Disconnect the battery negative lead.

3 Remove the protective sleeve from thewiring plug (where applicable), thendisconnect the wiring from the switch.4 Unscrew the switch from the cylinder block,and recover the sealing washer. Be preparedfor oil spillage, and if the switch is to be leftremoved from the engine for any length oftime, plug the hole in the cylinder block.

Refitting5 Examine the sealing washer for signs ofdamage or deterioration and if necessaryrenew.6 Refit the switch, complete with washer, andtighten it securely. Reconnect the wiringconnector.7 Lower the vehicle to the ground then checkand, if necessary, top-up the engine oil asdescribed in Chapter 1.

14 Oil level sensor -removal and refitting 2

According to model the oil level sensor islocated on the front side of the cylinder blockjust to the right of the oil filter, or on the rearleft-hand side of the cylinder block.

The removal and refitting procedure is asdescribed for the oil pressure switch inSection 13. Access is most easily obtainedfrom underneath the vehicle (see illustration).

1 Ignition system - general information

Breakerless Electronic ignition system

All carburettor models, and models fittedwith the Bosch L3.1-Jetronic and Bosch LU2-Jetronic fuel injection systems are equipped

with a breakerless electronic ignition systemis used. The system comprises solely of theHT ignition coil and a distributor mounted onthe left-hand end of the cylinder head anddriven by the camshaft. On carburettormodels the coil is mounted on a bracketattached to the cylinder block, and on modelsfitted with L3.1 and LU2 systems it is mountedon the inlet manifold.

The distributor contains a reluctor mountedonto its shaft and a magnet and stator fixed to

its body. The ignition amplifier unit is alsomounted onto the side of the distributor body.The system operates as follows.

When the ignition is switched on but theengine is stationary the transistors in theamplifier unit prevent current flowing throughthe ignition system primary (LT) circuit.

As the crankshaft rotates, the reluctormoves through the magnetic field created bythe stator. When the reluctor teeth are inalignment with the stator projections a small

AC voltage is created. The amplifier unit usesthis voltage to switch the transistors in theunit and complete the ignition system primary(LT) circuit.

As the reluctor teeth move out of alignmentwith the stator projections the AC voltagechanges and the transistors in the amplifierunit are switched again to interrupt theprimary (LT) circuit. This causes a high voltageto be induced in the coil secondary (HT)windings which then travels down the HT leadto the distributor and onto the relevant sparkplug.

A TDC sensor is fitted to the rear of theflywheel but the sensor is not part of theignition system. It is there to be used fordiagnostic purposes only.

Integral ignition/fuel injection system

On fuel-injected models except the L3.1and LU2 systems, the ignition system isintegrated with the fuel injection system toform a combined engine management systemunder the control of one ECU (See therelevant Part of Chapter 4 for furtherinformation).

The Bosch Motronic ML4.1 and Fenix 1Bsystems retain the distributor cap and rotorarm assembly in order to distribute the sparkto the cylinders, together with a conventionalignition coil.

All other models use a static (distribu-torless) ignition system, consisting only of afour output ignition coil. The ignition coilactually consists of two separate HT coilswhich supply two cylinders each (one coilsupplies cylinders 1 and 4, and the othercylinders 2 and 3). Under the control of theECU, the ignition coil operates on the “wastedspark” principle, ie. each spark plug sparkstwice for every cycle of the engine, once onthe compression stroke and once on theexhaust stroke - the spark on the exhauststroke has no effect on the running of theengine, and is therefore “wasted”. The ECUuses its inputs from the various sensors tocalculate the required ignition advance settingand coil charging time.

On some models a knock sensor isincorporated into the ignition system. Thesensor is mounted onto the cylinder head andprevents the engine “pinking” under load. Thesensor is sensitive to vibration and detects theknocking which occurs when the engine startsto “pink” (pre-ignite). The knock sensor sendsan electrical signal to the ECU which in turnretards the ignition advance setting until the“pinking” ceases.

Direct ignition systemThe ignition system on 1998 cc XU10J4

(16-valve) models is of the “direct” type. Thesystem components consist of two amplifiermodules, four ignition HT coils, and a knocksensor. The ignition system is integrated withthe fuel injection system, to form a combinedengine management system under the control

of one ECU via the ignition amplifier modules.Each ignition amplifier module operates two

HT coils; the ignition HT coils are integral withthe plug caps, and are pushed directly ontothe spark plugs, one for each plug. Thisremoves the need for any HT leadsconnecting the coils to the plugs. The ECUuses the inputs from the various sensors tocalculate the required ignition advance settingand coil charging time.

The knock sensor is mounted onto thecylinder head, and prevents the engine“pinking” under load. The sensor detectsabnormal vibration, and is thus able to detectthe knocking which occurs when the enginestarts to “pink” (pre-ignite). The knock sensorsends an electrical signal to the ECU, which inturn retards the ignition advance setting untilthe “pinking” ceases.

2 Ignition system - testing 2

Breakerless Electronic ignition systemNote: Refer to the precautions given inSection 1 of Part A of this Chapter beforestarting work. Always switch off the ignitionbefore disconnecting or connecting anycomponent and when using a multi-meter tocheck resistances.

General1 The components of electronic ignitionsystems are normally very reliable; most faultsare far more likely to be due to loose or dirtyconnections or to “tracking” of HT voltagedue to dirt, dampness or damaged insulationthan to the failure of any of the system’scomponents. Always check all wiringthoroughly before condemning an electricalcomponent and work methodically toeliminate all other possibilities before decidingthat a particular component is faulty.2 The old practice of checking for a spark byholding the live end of an HT lead a shortdistance away from the engine is notrecommended; not only is there a high risk ofa powerful electric shock, but the HT coil oramplifier unit will be damaged. Similarly,never try to “diagnose” misfires by pulling offone HT lead at a time.

Engine will not start3 If the engine either will not turn over at all,or only turns very slowly, check the batteryand starter motor. Connect a voltmeter acrossthe battery terminals (meter positive probe tobattery positive terminal), disconnect theignition coil HT lead from the distributor capand earth it, then note the voltage readingobtained while turning over the engine on thestarter for (no more than) ten seconds. If thereading obtained is less than approximately9.5 volts, first check the battery, starter motorand charging system as described in therelevant Sections of this Chapter.4 If the engine turns over at normal speed butwill not start, check the HT circuit byconnecting a timing light (following themanufacturer’s instructions) and turning theengine over on the starter motor; if the lightflashes, voltage is reaching the spark plugs,so these should be checked first. If the lightdoes not flash, check the HT leadsthemselves followed by the distributor cap,carbon brush and rotor arm using theinformation given in Chapter 1.5 If there is a spark, check the fuel system forfaults referring to the relevant part of Chapter4 for further information.6 If there is still no spark, check the voltage atthe ignition HT coil “+” terminal; it should bethe same as the battery voltage (ie, at least11.7 volts). If the voltage at the coil is morethan 1 volt less than that at the battery, checkthe feed back through the fusebox andignition switch to the battery and its earth untilthe fault is found.7 If the feed to the HT coil is sound, check thecoil’s primary and secondary windingresistance as described later in this Section;renew the coil if faulty, but be careful to checkcarefully the condition of the LT connectionsthemselves before doing so, to ensure thatthe fault is not due to dirty or poorly-fastenedconnectors.8 If the HT coil is in good condition, the faultis probably within the amplifier unit ordistributor stator assembly. Testing of thesecomponents should be entrusted to aPeugeot dealer.

Engine misfires9 An irregular misfire suggests either a looseconnection or intermittent fault on the primarycircuit, or an HT fault on the coil side of therotor arm.10 With the ignition switched off, checkcarefully through the system ensuring that allconnections are clean and securely fastened.If the equipment is available, check the LTcircuit as described above.11 Check that the HT coil, the distributor capand the HT leads are clean and dry. Check theleads themselves and the spark plugs (bysubstitution, if necessary), then check thedistributor cap, carbon brush and rotor arm asdescribed in Chapter 1.12 Regular misfiring is almost certainly due toa fault in the distributor cap, HT leads or spark

5B•2 Ignition system

Warning: Voltages produced byan electronic ignition systemare considerably higher thanthose produced by conventional

ignition systems. Extreme care must betaken when working on the system withthe ignition switched on. Persons withsurgically-implanted cardiac pacemakerdevices should keep well clear of theignition circuits, components and testequipment.

plugs. Use a timing light (paragraph 4 above)to check whether HT voltage is present at allleads.13 If HT voltage is not present on anyparticular lead, the fault will be in that lead orin the distributor cap. If HT voltage is presenton all leads, the fault will be in the sparkplugs; check and renew them if there is anydoubt about their condition.14 If no HT voltage is present, check the HTcoil; its secondary windings may be breakingdown under load.

Integral and Direct ignition systems15 If a fault appears in the enginemanagement (fuel injection/ignition) systemfirst ensure that the fault is not due to a poorelectrical connection or poor maintenance; ie,check that the air cleaner filter element isclean, the spark plugs are in good conditionand correctly gapped, that the enginebreather hoses are clear and undamaged,referring to Chapter 1 for further information.Also check that the accelerator cable iscorrectly adjusted as described in the relevantpart of Chapter 4. If the engine is running veryroughly, check the compression pressuresand the valve clearances as described inChapter 2A.16 On systems with a distributor cap androtor arm, check these items as described inthe previous sub-section.17 If these checks fail to reveal the cause ofthe problem the vehicle should be taken to asuitably equipped Peugeot dealer for testing.A wiring block connector is incorporated in

the engine management circuit into which aspecial electronic diagnostic tester can beplugged. The tester will locate the fault quicklyand simply alleviating the need to test all thesystem components individually which is atime consuming operation that carries a highrisk of damaging the ECU.18 The only other ignition system checkswhich can be carried out by the homemechanic are those described in Chapter 1,relating to the spark plugs, and the ignitioncoil test described in this Chapter. Ifnecessary, the system wiring and wiringconnectors can be checked as described inChapter 12 ensuring that the ECU wiringconnector(s) have first been disconnected.

3 Ignition HT coil(s) - removal, testing and refitting 2

Direct ignition models10 Disconnect the battery negative terminal.There are four separate ignition HT coils, oneon the top of each spark plug.11 To gain access to the coils, undo the eightbolts, noting the correct fitted position of thewiring clip, and remove the access cover fromthe centre of the cylinder head cover.12 To remove an HT coil, depress theretaining clip and disconnect the wiringconnector, then pull the coil off the spark plugand remove it along with its rubber seal.

Testing13 Testing of the coil consists of using amultimeter set to its resistance function, tocheck the primary (LT “+’“to “-” terminals) andsecondary (LT “+” to HT lead terminal)windings for continuity, bearing in mind thaton the four output, static type HT coil thereare two sets of each windings. Compare theresults obtained to those given in the Specifi-cations at the start of this Chapter. Note theresistance of the coil windings will vary slightlyaccording to the coil temperature, the resultsin the Specifications are approximate valuesfor when the coil is at 20°C.14 Check that there is no continuity betweenthe HT lead terminal and the coil body/mounting bracket.

15 If the coil is thought to be faulty, have yourfindings confirmed by a Peugeot dealer beforerenewing the coil.

6 Ignition timing - checking and adjustment 3

Breakerless Electronic ignition system1 To check the ignition timing, a stroboscopictiming light will be required. It is alsorecommended that the flywheel timing mark ishighlighted as follows.2 Remove the plastic cover from the apertureon the front of the transmission clutchhousing. Using a socket and suitableextension bar on the crankshaft pulley bolt,slowly turn the engine over until the timingmark (a straight line) scribed on the edge ofthe flywheel appears in the aperture. Highlightthe line with quick-drying white paint - typist’scorrection fluid is ideal (see illustrations).3 Start the engine, allow it to warm up tooperating temperature, and then stop it.4 Disconnect the vacuum hose from thedistributor diaphragm, and plug the hose end.5 Connect the timing light to No 1 cylinderspark plug lead (No 1 cylinder is at thetransmission end of the engine) as describedin the timing light manufacturer’s instructions.6 Start the engine, allowing it to idle at thespecified speed, and point the timing light at

the transmission housing aperture. Theflywheel timing mark should be aligned withthe appropriate notch on the timing plate(refer to the Specifications for the correctsetting). The numbers on the plate indicatedegrees Before Top Dead Centre (BTDC).7 If adjustment is necessary, slacken the twodistributor mounting nuts, then slowly rotatethe distributor body as required until theflywheel mark and the timing plate notch arebrought into alignment. Once the marks arecorrectly aligned, hold the distributorstationary and tighten its mounting nuts.Recheck that the timing marks are stillcorrectly aligned and, if necessary, repeat theadjustment procedure.8 When the timing is correctly set, increasethe engine speed, and check that the pulleymark advances to beyond the beginning ofthe timing plate reference marks, returning tothe specified mark when the engine is allowedto idle. This shows that the centrifugaladvance mechanism is functioning; if adetailed check is thought necessary, this mustbe left to a Peugeot dealer having thenecessary equipment. Reconnect the vacuumhose to the distributor, and repeat the check.The rate of advance should significantlyincrease if the vacuum diaphragm isfunctioning correctly, but again a detailed

check must be left to a Peugeot dealer.9 When the ignition timing is correct, stop theengine and disconnect the timing light.

Integral and Direct ignition systems10 On these systems, there are no timingmarks on the flywheel or crankshaft pulley.The timing is constantly being monitored andadjusted by the engine management ECU,and nominal values cannot be given.Therefore, it is not possible for the homemechanic to check the ignition timing.11 The only way in which the ignition timingcan be checked is using special electronictest equipment, connected to the enginemanagement system diagnostic connector(refer to the relevant Part of Chapter 4 forfurther information).12 On models with Magneti Marelli enginemanagement systems, adjustment of theignition timing is possible. However,adjustments can be made only by re-programming the ECU using the special testequipment (see relevant Part of Chapter 4).13 On all other models, with Bosch enginemanagement systems, no adjustment of theignition timing is possible. Should the ignitiontiming be incorrect, then a fault must bepresent in the engine management system.

1 General information

The braking system is of the servo-assisted, dual-circuit hydraulic type. Thearrangement of the hydraulic system is suchthat each circuit operates one front and onerear brake from a tandem master cylinder.Under normal circumstances, both circuitsoperate in unison. However, in the event ofhydraulic failure in one circuit, full brakingforce will still be available at two wheels.

Some large-capacity engine models havedisc brakes all round as standard; othermodels are fitted with front disc brakes andrear drum brakes. ABS is fitted as standard tocertain models, and is offered as an option onmost other models (refer to Section 23 forfurther information on ABS operation).

The front disc brakes are actuated bysingle-piston sliding type calipers, whichensure that equal pressure is applied to eachdisc pad.

On models with rear drum brakes, the rearbrakes incorporate leading and trailing shoes,which are actuated by twin-piston wheelcylinders. On models not equipped with anunderbody-mounted rear brake pressureregulating valve, the wheel cylindersincorporate integral pressure-regulatingvalves, which control the hydraulic pressureapplied to the rear brakes. The regulatingvalves help to prevent rear wheel lock-upduring emergency braking. On some models,an underbody-mounted load-sensitive rearpressure-regulating valve is fitted. A self-adjust mechanism is incorporated, toautomatically compensate for brake shoewear. As the brake shoe linings wear, thefootbrake operation automatically operatesthe adjuster mechanism, which effectively

lengthens the shoe strut and repositions thebrake shoes, to remove the lining-to-drumclearance.

On models with rear disc brakes, thebrakes are actuated by single-piston slidingcalipers which incorporate mechanicalhandbrake mechanisms. A load-sensitivepressure-regulating valve is fitted to regulatethe hydraulic pressure applied to the rearbrakes. The regulating valve is similar to thatfitted to drum brake models with ABS, andhelps to prevent rear wheel lock-up duringemergency braking.

On all models, the handbrake provides anindependent mechanical means of rear brakeapplication.

Note: When servicing any part of thesystem, work carefully and methodically; alsoobserve scrupulous cleanliness whenoverhauling any part of the hydraulic system.Always renew components (in axle sets, whereapplicable) if in doubt about their condition,and use only genuine Peugeot replacementparts, or at least those of known good quality.Note the warnings given in “Safety first” and atrelevant points in this Chapter concerning thedangers of asbestos dust and hydraulic fluid.

2 Hydraulic system - bleeding 2

General1 The correct operation of any hydraulicsystem is only possible after removing all airfrom the components and circuit; this isachieved by bleeding the system.2 During the bleeding procedure, add onlyclean, unused hydraulic fluid of therecommended type; never re-use fluid thathas already been bled from the system.Ensure that sufficient fluid is available beforestarting work.3 If there is any possibility of incorrect fluidbeing already in the system, the brakecomponents and circuit must be flushedcompletely with uncontaminated, correctfluid, and new seals should be fitted to thevarious components.4 If hydraulic fluid has been lost from thesystem, or air has entered because of a leak,ensure that the fault is cured beforeproceeding further.

Warning: Hydraulic fluid ispoisonous; wash offimmediately and thoroughly inthe case of skin contact, and

seek immediate medical advice if any fluidis swallowed or gets into the eyes. Certaintypes of hydraulic fluid are inflammable,and may ignite when allowed into contactwith hot components; when servicing anyhydraulic system, it is safest to assume

that the fluid is inflammable, and to takeprecautions against the risk of fire asthough it is petrol that is being handled.Hydraulic fluid is also an effective paintstripper, and will attack plastics; if any isspilt, it should be washed off immediately,using copious quantities of fresh water.Finally, it is hygroscopic (it absorbsmoisture from the air) - old fluid may becontaminated and unfit for further use.When topping-up or renewing the fluid,always use the recommended type, andensure that it comes from a freshly-opened sealed container.

Warning: Do not attempt tobleed any part of the hydraulicsystem on models equippedwith the Bendix “integral” ABS.

Special equipment is required, and thetask must be referred to a Peugeot dealer.

5 Park the vehicle on level ground, switch offthe engine and select first or reverse gear, thenchock the wheels and release the handbrake.6 Check that all pipes and hoses are secure,unions tight and bleed screws closed. Cleanany dirt from around the bleed screws.7 Unscrew the master cylinder reservoir cap,and top the master cylinder reservoir up to the“MAX” level line; refit the cap loosely, andremember to maintain the fluid level at leastabove the “MIN” level line throughout theprocedure, or there is a risk of further airentering the system.8 There are a number of one-man, do-it-yourselfbrake bleeding kits currently available from motor accessory shops. It is recommended thatone of these kits is used whenever possible, as they greatly simplify the bleeding operation,and also reduce the risk of expelled air and fluid being drawn back into the system. If such a kit is not available, the basic (two-man) method must be used, which is described indetail below.9 If a kit is to be used, prepare the vehicle asdescribed previously, and follow the kitmanufacturer’s instructions, as the proceduremay vary slightly according to the type beingused; generally, they are as outlined below inthe relevant sub-section.10 Whichever method is used, the samesequence must be followed to ensure theremoval of all air from the system.

Bleeding - basic (two-man) method11 Collect a clean glass jar, a suitable lengthof plastic or rubber tubing which is a tight fitover the bleed screw, and a ring spanner to fitthe screw. The help of an assistant will also berequired.12 Remove the dust cap from the first screwin the sequence (see illustrations). Fit thespanner and tube to the screw, place the

other end of the tube in the jar, and pour insufficient fluid to cover the end of the tube.13 Ensure that the master cylinder reservoirfluid level is maintained at least above the“MIN” level line throughout the procedure.14 Have the assistant fully depress the brakepedal several times to build up pressure, thenmaintain it on the final downstroke.15 While pedal pressure is maintained,unscrew the bleed screw (approximately oneturn) and allow the compressed fluid and air toflow into the jar. The assistant should maintainpedal pressure, following it down to the floor ifnecessary, and should not release it untilinstructed to do so. When the flow stops,tighten the bleed screw again, have theassistant release the pedal slowly, andrecheck the reservoir fluid level.16 Repeat the steps given in paragraphs 14and 15 until the fluid emerging from the bleedscrew is free from air bubbles. If the mastercylinder has been drained and refilled, and airis being bled from the first screw in thesequence, allow approximately five secondsbetween cycles for the master cylinderpassages to refill.17 When no more air bubbles appear, tightenthe bleed screw securely, remove the tubeand spanner, and refit the dust cap. Do notovertighten the bleed screw.18 Repeat the procedure on the remainingscrews in the sequence, until all air isremoved from the system and the brake pedalfeels firm again.

Bleeding - using a one-way valve kit19 As their name implies, these kits consistof a length of tubing with a one-way valvefitted, to prevent expelled air and fluid beingdrawn back into the system; some kits includea translucent container, which can bepositioned so that the air bubbles can bemore easily seen flowing from the end of thetube.20 The kit is connected to the bleed screw,which is then opened. The user returns to thedriver’s seat, depresses the brake pedal witha smooth, steady stroke, and slowly releasesit; this is repeated until the expelled fluid isclear of air bubbles (see illustration).21 Note that these kits simplify work so

much that it is easy to forget the mastercylinder reservoir fluid level; ensure that this ismaintained at least above the “MIN” level lineat all times.

Bleeding - using a pressure-bleeding kit22 These kits are usually operated by thereservoir of pressurised air contained in thespare tyre. However, note that it will probablybe necessary to reduce the pressure to alower level than normal; refer to theinstructions supplied with the kit.23 By connecting a pressurised, fluid-filledcontainer to the master cylinder reservoir,bleeding can be carried out simply by openingeach screw in turn (in the specified sequence),and allowing the fluid to flow out until no moreair bubbles can be seen in the expelled fluid.24 This method has the advantage that thelarge reservoir of fluid provides an additionalsafeguard against air being drawn into thesystem during bleeding.25 Pressure-bleeding is particularly effectivewhen bleeding “difficult” systems, or whenbleeding the complete system at the time ofroutine fluid renewal.

All methods26 When bleeding is complete, and firmpedal feel is restored, wash off any spilt fluid,tighten the bleed screws securely, and refittheir dust caps.27 Check the hydraulic fluid level in themaster cylinder reservoir, and top-up ifnecessary (Chapter 1).28 Discard any hydraulic fluid that has beenbled from the system; it will not be fit for re-use.29 Check the feel of the brake pedal. If itfeels at all spongy, air must still be present inthe system, and further bleeding is required.Failure to bleed satisfactorily after areasonable repetition of the bleedingprocedure may be due to worn mastercylinder seals.30 On models with ABS, reconnect the wiringconnector to the hydraulic modulatorassembly.

3 Hydraulic pipes and hoses -renewal 4

Note: Before starting work, refer to the note atthe beginning of Section 2 concerning thedangers of hydraulic fluid.1 If any pipe or hose is to be renewed,minimise fluid loss by first removing themaster cylinder reservoir cap, then tighteningit down onto a piece of polythene to obtain anairtight seal. Alternatively, flexible hoses canbe sealed, if required, using a proprietarybrake hose clamp; metal brake pipe unionscan be plugged (if care is taken not to allowdirt into the system) or capped immediatelythey are disconnected. Place a wad of ragunder any union that is to be disconnected, tocatch any spilt fluid.2 If a flexible hose is to be disconnected,unscrew the brake pipe union nut beforeremoving the spring clip which secures thehose to its mounting bracket (seeillustration).3 To unscrew the union nuts, it is preferableto obtain a brake pipe spanner of the correctsize; these are available from most largemotor accessory shops. Failing this, a close-fitting open-ended spanner will be required,though if the nuts are tight or corroded, theirflats may be rounded-off if the spanner slips.In such a case, a self-locking wrench is oftenthe only way to unscrew a stubborn union, butit follows that the pipe and the damaged nutsmust be renewed on reassembly. Alwaysclean a union and surrounding area beforedisconnecting it. If disconnecting acomponent with more than one union, make acareful note of the connections beforedisturbing any of them.4 If a brake pipe is to be renewed, it can beobtained, cut to length and with the unionnuts and end flares in place, from Peugeotdealers. All that is then necessary is to bend itto shape, following the line of the original,before fitting it to the car. Alternatively, mostmotor accessory shops can make up brakepipes from kits, but this requires very carefulmeasurement of the original, to ensure thatthe replacement is of the correct length. Thesafest answer is usually to take the original tothe shop as a pattern.

5 On refitting, do not overtighten the unionnuts. It is not necessary to exercise bruteforce to obtain a sound joint.6 Ensure that the pipes and hoses arecorrectly routed, with no kinks, and that theyare secured in the clips or brackets provided.After fitting, remove the polythene from thereservoir, and bleed the hydraulic system asdescribed in Section 2. Wash off any spiltfluid, and check carefully for fluid leaks.

4 Front brake pads - renewal 2

1 Apply the handbrake, then jack up the frontof the vehicle and support it on axle stands(see “Jacking and Vehicle Support”). Removethe front roadwheels.2 Trace the brake pad wear sensor wiringback from the pads, and disconnect it fromthe wiring connector (see illustration). Notethe routing of the wiring, and free it from anyrelevant retaining clips.3 Push the piston into its bore by pulling thecaliper outwards.4 There are two different types of front brakecaliper fitted to the models covered in thismanual as follows.a) Models with solid front discs -

Bendix calipers.b) Models with ventilated front discs -

Girling calipers.

Warning: Renew both sets offront brake pads at the sametime - never renew the pads ononly one wheel, as uneven

braking may result. Note that the dustcreated by wear of the pads may containasbestos, which is a health hazard. Neverblow it out with compressed air, and don’tinhale any of it. An approved filteringmask should be worn when working onthe brakes. DO NOT use petrol orpetroleum-based solvents to clean brakeparts; use brake cleaner or methylatedspirit only.

Bendix caliperNote: A new pad retaining plate spring clipshould be used on refitting.5 Using pliers, extract the small spring clipfrom the pad retaining plate, and then slidethe plate out of the caliper (see illustrations).6 Withdraw the pads from the caliper, thenmake a note of the correct fitted position ofeach anti-rattle spring, and remove the springfrom each pad (see illustration).7 First measure the thickness of each brakepad’s friction material (see illustration). Ifeither pad is worn at any point to the specifiedminimum thickness or less, all four pads mustbe renewed. Also, the pads should be renewedif any are fouled with oil or grease; as there isno satisfactory way of degreasing frictionmaterial, once contaminated. If any of thebrake pads are worn unevenly, or are fouledwith oil or grease, trace and rectify the causebefore reassembly. New brake pads and springkits are available from Peugeot dealers.8 If the brake pads are still serviceable,carefully clean them using a clean, fine wirebrush or similar, paying particular attention tothe sides and back of the metal backing. Cleanout the grooves in the friction material, andpick out any large embedded particles of dirtor debris. Carefully clean the pad locations inthe caliper body/mounting bracket.9 Prior to fitting the pads, check that theguide pins are free to slide easily in the caliperbody/mounting bracket, and check that therubber guide pin gaiters are undamaged.Brush the dust and dirt from the caliper andpiston, but do not inhale it, as it is injurious to

health. Inspect the dust seal around the pistonfor damage, and the piston for evidence offluid leaks, corrosion or damage. If attentionto any of these components is necessary,refer to Section 10.10 If new brake pads are to be fitted, thecaliper piston must be pushed back into thecylinder to make room for them. Either use aG-clamp or similar tool, or use suitable piecesof wood as levers. Provided that the mastercylinder reservoir has not been overfilled withhydraulic fluid, there should be no spillage,but keep a careful watch on the fluid levelwhile retracting the piston. If the fluid levelrises above the “MAX” level line at any time,the surplus should be siphoned off or ejectedvia a plastic tube connected to the bleedscrew (see Section 2). Note: Do not syphonthe fluid by mouth, as it is poisonous; use asyringe or an old poultry baster.11 Fit the anti-rattle springs to the pads, sothat when the pads are installed in the caliper,the spring end will be located at the oppositeend of the pad in relation to the pad retainingplate.12 Locate the pads in the caliper, ensuringthat the friction material of each pad is againstthe brake disc, and check that the anti-rattlespring ends are at the opposite end of the padto which the retaining plate is to be inserted.Note that if the pads are installed correctly,looking at the pads from the front of thevehicle, the innermost pad groove must behigher than the outer pad groove. Ensure thatthe pads are fitted correctly beforeproceeding (see illustrations).

13 Slide the retaining plate into place, andinstall the new small spring clip at its innerend. It may be necessary to file an entrychamfer on the edge of the retaining plate, toenable it to be fitted without difficulty.14 Reconnect the brake pad wear sensorwiring connectors, ensuring that the outerwire is correctly routed through the anti-rattlespring loops, and that both wires passthrough the loop of the bleed screw cap.15 Depress the brake pedal repeatedly, untilthe pads are pressed into firm contact withthe brake disc, and normal (non-assisted)pedal pressure is restored.16 Repeat the above procedure on theremaining front brake caliper.

Discard the guidepin bolt - a new bolt must be used on refitting.20 With the lower guide pin bolt removed,pivot the caliper upwards, away from thebrake pads and mounting bracket, taking carenot to strain the flexible brake hose (seeillustration).21 Withdraw the two brake pads from thecaliper mounting bracket, and examine themas described above in paragraphs 7 to 10.22 Apply a little brake grease to the rear ofthe pads, then Install the pads in the calipermounting bracket, ensuring that the frictionmaterial of each pad is against the brake disc(see illustration).23 Position the caliper over the pads, andpass the pad warning sensor wiring throughthe caliper aperture and underneath theretaining clip (see illustration). If the threadsof the new guide pin bolt are not already pre-

coated with locking compound, apply asuitable thread-locking compound to them.Pivot the caliper into position, then install theguide pin bolt, tightening to the specifiedtorque setting while retaining the guide pinwith an open-ended spanner. Whereapplicable, refit the dust cover to the guidepin.24 Reconnect the brake pad wear sensorwiring connector, ensuring that the wiring iscorrectly routed through the loop of thecaliper bleed screw cap.25 Depress the brake pedal repeatedly, untilthe pads are pressed into firm contact withthe brake disc, and normal (non-assisted)pedal pressure is restored.26 Repeat the procedure on the remainingfront brake caliper.27 Refit the roadwheels, then lower thevehicle to the ground and tighten theroadwheel bolts to the specified torquesetting.28 Check the hydraulic fluid level asdescribed in Chapter 1.

All calipers29 New pads will not give full brakingefficiency until they have bedded in. Beprepared for this, and avoid hard braking asfar as possible for the first hundred miles or soafter pad renewal.

5 Rear brake pads - renewal 2

Note: A new upper caliper guide pin bolt mustbe used on refitting.1 Chock the front wheels, then jack up therear of the vehicle and support securely onaxle stands (see “Jacking and VehicleSupport”). Remove the rear roadwheels.2 Disconnect the handbrake cable end fromthe operating lever on the caliper.3 Where applicable, prise off the dust cover,then slacken and remove the upper caliperguide pin bolt, using a slim open-endedspanner to prevent the guide pin itself fromrotating. Discard the guide pin bolt - a newbolt must be used on refitting.4 With the upper guide pin bolt removed,pivot the caliper downwards, away from thebrake pads and mounting bracket, taking carenot to strain the flexible brake hose.5 Withdraw the brake pads from the calipermounting bracket.6 First measure the thickness of each brakepad’s friction material. If either pad is worn atany point to the specified minimum thicknessor less, all four pads must be renewed. Also,the pads should be renewed if any are fouledwith oil or grease; there is no satisfactory wayof degreasing friction material, oncecontaminated.

Provided thatthe master cylinder reservoir has not beenoverfilled with hydraulic fluid, there should beno spillage, but keep a careful watch on thefluid level while retracting the piston. If thefluid level rises above the “MAX” level line atany time, the surplus should be siphoned offor ejected via a plastic tube connected to thebleed screw (see Section 2). Note: Do notsyphon the fluid by mouth, as it is poisonous;use a syringe or an old poultry baster.10 Retract the caliper piston by applyingpressure, and turning it clockwise. A specialtool is available for this purpose but a pair ofcirclip pliers or any similar tool can be usedinstead. Take care not to damage the surfaceof the piston. Turn the piston to position thenotches in the piston on the centreline of theslot in the front of the caliper.11 Fit the pads, sliding them into position inthe caliper bracket, with the friction materialagainst the disc.12 If the threads of the new guide pin bolt arenot already pre-coated with lockingcompound, apply a suitable thread-lockingcompound to them. Pivot the caliper intoposition, then install the guide pin bolt,tightening to the specified torque setting whileretaining the guide pin with an open-endedspanner. Where applicable, refit the dustcover to the guide pin.13 Reconnect the handbrake cable to thecaliper.

Beprepared for this, and avoid hard braking asfar as possible for the first hundred miles or soafter pad renewal.

6 Rear brake shoes - renewal 3

1 Remove the brake drum (see Section 9).2 Working carefully, and taking the necessaryprecautions, remove all traces of brake dustfrom the brake drum, backplate and shoes.3 Measure the thickness of the frictionmaterial of each brake shoe at several points;if either shoe is worn at any point to thespecified minimum thickness or less, all fourshoes must be renewed as a set. The shoesshould also be renewed if any are fouled withoil or grease; there is no satisfactory way ofdegreasing friction material, oncecontaminated.4 If any of the brake shoes are worn unevenly,or fouled with oil or grease, trace and rectifythe cause before reassembly.5 To renew the brake shoes, proceed asdescribed under the relevant sub-heading.

Bendix brake shoesNote: The components encountered may varyin detail, but the principles described in thefollowing paragraphs are equally applicable toall models. Make a careful note of the fittedpositions of all components before dismantling.6 On early models, unhook the shoe retainersprings from the brake backplate using aforked tool similar to that shown. The tool canbe improvised using a screwdriver with anotch in the blade. The tool is pushed throughthe centre of the spring, and the spring hookcan then be released from the backplate (seeillustrations).7 On later models, using a pair of pliers,remove the shoe retainer spring cups bydepressing and turning them through 90º (seeillustration). With the cups removed, lift offthe springs and withdraw the retainer pins.8 Ease the shoes out one at a time from thelower pivot point, to release the tension of thereturn spring, then disconnect the lower returnspring from both shoes (see illustration).9 Ease the upper end of both shoes out fromtheir wheel cylinder locations, taking care notto damage the wheel cylinder seals, anddisconnect the handbrake cable from thetrailing shoe (see Haynes Hint). The brakeshoe and adjuster strut assembly can then bemanoeuvred out of position and away fromthe backplate. Do not depress the brake pedaluntil the brakes are reassembled.

Warning: Brake shoes must berenewed on both rear wheels atthe same time - never renew theshoes on only one wheel, as

uneven braking may result. Also, the dustcreated by wear of the shoes may containasbestos, which is a health hazard. Neverblow it out with compressed air, and don’tinhale any of it. An approved filteringmask should be worn when working onthe brakes. DO NOT use petrol orpetroleum-based solvents to clean brakeparts; use brake cleaner or methylatedspirit only.

10 With the shoe and adjuster strut assemblyon a bench, make a note of the correct fittedpositions of the springs and adjuster strut, touse as a guide on reassembly. Release thehandbrake lever stop-peg (if not alreadydone), then carefully detach the adjuster strutbolt retaining spring from the leading shoe.Disconnect the upper return spring, thendetach the leading shoe and return springfrom the trailing shoe and strut assembly.Unhook the spring securing the adjuster strutto the trailing shoe, and separate the two.11 If genuine Peugeot brake shoes are beinginstalled, it will be necessary to remove thehandbrake lever from the original trailing shoe,and install it on the new shoe. Secure thelever in position with a new retaining clip. Allreturn springs should be renewed, regardlessof their apparent condition; spring kits arealso available from Peugeot dealers.12 Withdraw the adjuster bolt from the strut,and carefully examine the assembly for signsof wear or damage. Pay particular attention tothe threads of the adjuster bolt and theknurled adjuster wheel, and renew ifnecessary. Note that left-hand and right-handstruts are not interchangeable - they aremarked “G” (gauche) and “D” (droit)respectively. Also note that the strut adjusterbolts are not interchangeable; the left-handstrut bolt has a left-handed thread, and theright-hand bolt a right-handed thread.13 Ensure that the components on the end ofthe strut are correctly positioned, then apply alittle high-melting-point grease to the threads

of the adjuster bolt (see illustration). Screwthe adjuster wheel onto the bolt until only asmall gap exists between the wheel and thehead of the bolt, then install the bolt in the strut.14 Fit the adjuster strut retaining spring tothe trailing shoe, ensuring that the shorterhook of the spring is engaged with the shoe.Attach the adjuster strut to the spring end,then ease the strut into position in its slot inthe trailing shoe.15 Engage the upper return spring with thetrailing shoe, then hook the leading shoe ontothe other end of the spring, and lever theleading shoe down until the adjuster bolt headis correctly located in its groove. Once thebolt is correctly located, hook its retainingspring into the slot on the leading shoe.16 Peel back the rubber protective caps, andcheck the wheel cylinder for fluid leaks orother damage; check that both cylinderpistons are free to move easily. Refer toSection 12, if necessary, for information onwheel cylinder renewal.17 Prior to installation, clean the backplate,and apply a smear of high-temperature brakegrease or anti-seize compound to all thosesurfaces of the backplate which bear on theshoes, particularly the wheel cylinder pistonsand lower pivot point (see illustration). Do notallow the lubricant to foul the friction material.18 Ensure that the handbrake lever stop-pegis correctly located against the edge of thetrailing shoe, and remove the elastic band orcable-tie (as applicable) fitted to the wheelcylinder.

19 Manoeuvre the shoe and strut assemblyinto position on the vehicle, and engage theupper end of both shoes with the wheelcylinder pistons. Attach the handbrake cableto the trailing shoe lever. Fit the lower returnspring to both shoes, and ease the shoes intoposition on the lower pivot point (seeillustrations).20 Tap the shoes to centralise them with thebackplate, then refit the shoe retainer pinsand springs, and secure them in position withthe spring cups.21 Using a screwdriver, turn the strutadjuster wheel to expand the shoes until thebrake drum just slides over the shoes.22 Refit the brake drum as described inSection 9.23 Repeat the above procedure on theremaining rear brake.24 Once both sets of rear shoes have beenrenewed, adjust the lining-to-drum clearanceby repeatedly depressing the brake pedal.Whilst depressing the pedal, have anassistant listen to the rear drums, to check

With the cup removed, liftoff the spring, then withdraw the retainer pinand remove the shoe from the backplate.Unhook the adjusting lever spring, andremove it from the leading shoe.30 Detach the adjuster strut, and remove itfrom the trailing shoe.31 Remove the trailing shoe retainer springcup, spring and pin as described above, thendetach the handbrake cable and remove theshoe from the vehicle. Do not depress thebrake pedal until the brakes are reassembled.

32 If genuine Peugeot brake shoes are beinginstalled, it will be necessary to remove theadjusting lever from the original leading shoe,and install it on the new shoe. All returnsprings should be renewed, regardless of theirapparent condition; spring kits are alsoavailable from Peugeot dealers.33 Withdraw the forked end from the adjusterstrut, and carefully examine the assembly forsigns of wear or damage. Pay particularattention to the threads and the knurledadjuster wheel, and renew if necessary. Notethat left-hand and right-hand struts are not

interchangeable; the left-hand fork has a left-handed thread, and the right-hand fork aright-handed thread.34 Peel back the rubber protective caps, andcheck the wheel cylinder for fluid leaks orother damage; check that both cylinderpistons are free to move easily. Refer toSection 12, if necessary, for information onwheel cylinder renewal.35 Prior to installation, clean the backplate,and apply a thin smear of high-temperaturebrake grease or anti-seize compound to allthose surfaces of the backplate which bear onthe shoes, particularly the wheel cylinderpistons and lower pivot point. Do not allowthe lubricant to foul the friction material.36 Ensure that the handbrake lever stop-pegis correctly located against the edge of thetrailing shoe, and remove the elastic band orcable-tie (as applicable) fitted to the wheelcylinder.37 Locate the upper end of the trailing shoein the wheel cylinder piston, then refit theretainer pin and spring, and secure it inposition with the spring cup. Connect thehandbrake cable to the lever.38 Screw in the adjuster wheel until theminimum strut length is obtained, then hookthe strut into position on the trailing shoe(note that the left and right-hand adjusters arenot interchangeable - see paragraph 33).Rotate the adjuster strut forked end, so thatthe cut-out of the fork will engage with theleading shoe adjusting lever once the shoe isinstalled (see illustration).39 Fit the spring to the leading shoeadjusting lever, so that the shorter hook of thespring engages with the lever.40 Slide the leading shoe assembly intoposition, ensuring that it is correctly engagedwith the adjuster strut fork, and that the forkcut-out is engaged with the adjusting lever.Ensure that the upper end of the shoe islocated in the wheel cylinder piston, thensecure the shoe in position with the retainerpin, spring and spring cup.41 Install the upper and lower return springs,then tap the shoes to centralise them with thebackplate.42 Using a screwdriver, turn the strutadjuster wheel to expand the shoes until thebrake drum just slides over the shoes.43 Refit the brake drum as described inSection 9.44 Repeat the above procedure on theremaining rear brake.45 Once both sets of rear shoes have beenrenewed, adjust the lining-to-drum clearance

by repeatedly depressing the brake pedal.Whilst depressing the pedal, have anassistant listen to the rear drums, to checkthat the adjuster strut is functioning correctly;if so, a clicking sound will be emitted by thestrut as the pedal is depressed.46 Check and, if necessary, adjust thehandbrake as described in Section 17.47 On completion, check the hydraulic fluidlevel as described in Chapter 1.

All shoes48 New shoes will not give full brakingefficiency until they have bedded in. Beprepared for this, and avoid hard braking asfar as possible for the first hundred miles or soafter shoe renewal.

7 Front brake disc - inspection,removal and refitting 2

Note: Before starting work, refer to the note atthe beginning of Section 4 concerning thedangers of asbestos dust.

InspectionNote: If either disc requires renewal, BOTHshould be renewed at the same time, toensure even and consistent braking. Newbrake pads should also be fitted.1 Apply the handbrake, then jack up the frontof the car and support it on axle stands (see“Jacking and Vehicle Support”). Remove theappropriate front roadwheel.2 Slowly rotate the brake disc so that the fullarea of both sides can be checked; removethe brake pads if better access is required tothe inboard surface. Light scoring is normal inthe area swept by the brake pads, but if heavyscoring or cracks are found, the disc must berenewed.3 It is normal to find a lip of rust and brakedust around the disc’s perimeter; this can bescraped off if required. If, however, a lip hasformed due to excessive wear of the brakepad swept area, then the disc’s thicknessmust be measured using a micrometer (seeillustration). Take measurements at severalplaces around the disc, at the inside andoutside of the pad swept area; if the disc has

worn at any point to the specified minimumthickness or less, the disc must be renewed.4 If the disc is thought to be warped, it can bechecked for run-out. Either use a dial gaugemounted on any convenient fixed point, whilethe disc is slowly rotated, or use feeler bladesto measure (at several points all around thedisc) the clearance between the disc and afixed point, such as the caliper mountingbracket (see illustration). If the measurementsobtained are at the specified maximum orbeyond, the disc is excessively warped, andmust be renewed; however, it is worthchecking first that the hub bearing is in goodcondition (Chapters 1 and/or 10). Also try theeffect of removing the disc and turning itthrough 180º, to reposition it on the hub; if therun-out is still excessive, the disc must berenewed.5 Check the disc for cracks, especiallyaround the wheel bolt holes, and any otherwear or damage, and renew if necessary.

Removal6 On models with Bendix calipers, removethe brake pads as described in Section 4.7 On models with Girling calipers, unscrewthe two bolts securing the caliper mountingbracket to the hub carrier (see illustration).Using a piece of wire or string, tie the caliperto the front suspension coil spring, to avoidplacing any strain on the fluid hose.8 Use chalk or paint to mark the relationshipof the disc to the hub, then remove thescrew(s) securing the brake disc to the hub,and remove the disc (see illustration). If it istight, lightly tap its rear face with a hide orplastic mallet.

Refitting9 Refitting is the reverse of the removalprocedure, noting the following points:a) Ensure that the mating surfaces of the

disc and hub are clean and flat.b) Align (if applicable) the marks made on

removal, and securely tighten the discretaining screws.

c) If a new disc has been fitted, use asuitable solvent to wipe any preservativecoating from the disc, before refitting thecaliper.

d) On models with Girling calipers, refit thecaliper as described in Section 10.

e) On models with Bendix calipers, refit thepads as described in Section 4.

f) Refit the roadwheel, then lower thevehicle to the ground and tighten theroadwheel bolts to the specified torque.On completion, repeatedly depress thebrake pedal until normal (non-assisted)pedal pressure returns.

Note: Before starting work, refer to the note atthe beginning of Section 4 concerning thedangers of asbestos dust.

Removal1 Chock the front wheels, then jack up therear of the vehicle and support it on axlestands (see “Jacking and Vehicle Support”).Remove the appropriate rear roadwheel.2 Remove the drum retaining screw (seeillustration).3 It should now be possible to withdraw thebrake drum by hand. It may be difficult toremove the drum due to the brake shoesbinding on the inner circumference of thedrum. If the brake shoes are binding, proceedas follows.a) First check that the handbrake is fully

released, then referring to Section 17 forfurther information, fully slacken thehandbrake cable adjuster nut, to obtainmaximum free play in the cable.

b) Insert a screwdriver through the accesshole in the rear of the backplate (prise outthe blanking plug, where applicable), so

that it contacts the handbrake operatinglever on the trailing brake shoe. Push thelever until the stop-peg slips behind thebrake shoe web, allowing the brake shoesto retract fully (see illustrations). Thebrake drum can now be withdrawn.

InspectionNote: If either drum requires renewal, BOTHshould be renewed at the same time, toensure even and consistent braking. Newbrake shoes should also be fitted.4 Working carefully, remove all traces ofbrake dust from the drum, but avoid inhalingthe dust, as it is injurious to health.5 Clean the outside of the drum, and check itfor obvious signs of wear or damage, such ascracks around the roadwheel bolt holes;renew the drum if necessary.6 Examine carefully the inside of the drum.Light scoring of the friction surface is normal,but if heavy scoring is found, the drum mustbe renewed. It is usual to find a lip on thedrum’s inboard edge which consists of amixture of rust and brake dust; this should bescraped away, to leave a smooth surfacewhich can be polished with fine (120- to 150-grade) emery paper. If, however, the lip is dueto the friction surface being recessed byexcessive wear, then the drum must berenewed.7 If the drum is thought to be excessivelyworn, or oval, its internal diameter must bemeasured at several points using an internal

micrometer. Take measurements in pairs, thesecond at right-angles to the first, andcompare the two, to check for signs of ovality.Provided that it does not enlarge the drum tobeyond the specified maximum diameter, itmay be possible to have the drum refinishedby skimming or grinding; if this is not possible,the drums on both sides must be renewed.Note that if the drum is to be skimmed, BOTHdrums must be refinished, to maintain aconsistent internal diameter on both sides.

Refitting8 If a new brake drum is to be installed, use asuitable solvent to remove any preservativecoating that may have been applied to itsinterior. Note that it may also be necessary toshorten the adjuster strut length, by rotatingthe strut wheel, to allow the drum to pass overthe brake shoes.9 Ensure that the handbrake lever stop-peg iscorrectly repositioned against the edge of thebrake shoe web (see illustration), and ensurethat the mating faces of the hub and brakedrum are clean, then slide the brake drumonto the hub.10 Refit and tighten the drum retainingscrew.11 Depress the footbrake several times tooperate the self-adjusting mechanism.12 Repeat the above procedure on theremaining rear brake assembly (wherenecessary), then check and, if necessary,adjust the handbrake cable as described inSection 17.13 On completion, refit the roadwheel(s),then lower the vehicle to the ground andtighten the wheel bolts to the specifiedtorque.

17 Handbrake - checking andadjustment 2

Checking1 The handbrake is correctly adjusted whenthe rear wheels are fully locked when thehandbrake lever has been pulled up by six toeight notches. This adjustment tolerance willbe maintained if the automatic adjustermechanism is operating correctly tocompensate for brake shoe/pad wear.2 To check the adjustment, proceed asfollows.3 Start the engine and release the handbrake.4 Depress the brake pedal fully two or threetimes with the engine running, then stop theengine.5 Chock the front wheels, then jack up therear of the vehicle, and support securely onaxle stands (see “Jacking and VehicleSupport”).6 Apply the handbrake between six to eightnotches, and check that both rear wheels arelocked. If the wheels do not lock, or if thewheels lock before the handbrake lever hasmoved through at least six notches, adjust themechanism as follows.

Adjustment - rear drum brakes7 With the vehicle raised and supported at

the rear, where applicable, remove the rearbody undershield for access to the handbrakecable adjuster (see illustration).8 Slacken the locknut on the handbrakeadjuster mechanism and turn the adjuster nutuntil the brake shoes are just beginning todrag on the drums.9 Pull up the handbrake lever, and check thatboth rear wheels are locked with the leverpulled up between six and eight notches. Ifnot, readjust using the adjuster nut asnecessary.10 With the mechanism correctly adjusted,tighten the adjuster locknut then, whereapplicable, refit the rear body undershield,and lower the vehicle to the ground.11 Check that the “handbrake on” warninglight illuminates with the handbrake lever atthe first notch of its travel. If necessary, adjustthe switch as described in Chapter 12.

23 Anti-lock braking system(ABS) - general information

General1 ABS is available as an option on certainmodels covered by this manual, and is fittedas standard equipment on some models. Thepurpose of the system is to prevent thewheel(s) locking during heavy braking. This isachieved by automatic release of the brake onthe relevant wheel, followed by re-applicationof the brake. The system comprises anelectronic control module, a hydraulicmodulator block, the hydraulic solenoidvalves and accumulators, the electrically-driven pump, and the roadwheel sensors.2 The system operates on all four wheels,and vehicles may be fitted with rear disc orrear drum brakes.3 The system prevents wheel lock-up byregulating the hydraulic pressure to thebrakes.4 Solenoids (which control the fluid pressureto the calipers) are controlled by the electroniccontrol unit, which itself receives signals fromthe wheel sensors (fitted to all four wheels),which monitor the speed of rotation of eachwheel. By comparing these speed signalsfrom the wheels, the control unit candetermine the speed at which the vehicle istravelling. It can then use this speed todetermine when a wheel is decelerating at anabnormal rate, compared to the speed of thevehicle, and therefore predicts when a wheelis about to lock. During normal operation, thesystem functions in the same way as a non-ABS braking system.5 The ABS system is fail-safe, and should afailure occur, a self-monitoring test facility isincorporated in the system which can be usedin conjunction with dealer test equipment forfault diagnosis.6 Three different types of ABS may be fitted,depending on model, as follows.

Bendix “integral” ABS7 This system is fitted to certain models up to1993 as standard equipment. The system isfitted instead of a conventional system, andthe brake pedal acts directly on the hydrauliccontrol unit, which replaces the mastercylinder and vacuum servo in a conventionalbraking system.8 The system operates at very high fluidpressure, typically 158 to 183 bar, generatedby an electric pump fitted to the modulatorassembly.9 The system is fail-safe and will continue tooperate even if one wheel sensor should fail.In the event of total failure, the control unit willrevert the system to normal braking.

Bendix “additional” ABS10 The Bendix “additional” system is fitted asan option to certain models, and the ABScomponents are fitted in addition to theconventional braking system components.11 The system uses the pressure providedby the conventional master cylinder andvacuum servo.12 The system is fail-safe, and conventionalbraking is maintained through the servo and master cylinder in the event of an ABSfailure.13 The braking system can be safely bled,and the fluid can be renewed as described inChapter 1, as the system operates using theconventional pressure supplied by the mastercylinder and servo.

Bosch 2E “additional” ABS14 The Bosch 2E additional system is fittedto certain later models from 1993, and issimilar to the Bendix “additional” systemdescribed previously.

1 General information

The independent front suspension is of theMacPherson strut type, incorporating coilsprings and integral telescopic shockabsorbers. The MacPherson struts arelocated by transverse lower suspension arms,which utilise rubber inner mounting bushes.The front hub carriers, which carry the wheelbearings, brake calipers and the hub/discassemblies, are bolted to the MacPhersonstruts. The hub carriers are connected to thelower arms via balljoints attached to the hubcarriers. A front anti-roll bar is fitted to allmodels. The anti-roll bar is rubber-mountedonto the subframe, and is connected to thelower arms via drop links.

The rear suspension is of the semi-independent trailing arm type, which consistsof two trailing arms, linked by a tubularcrossmember. A torsion bar is fittedtransversely between each trailing arm andthe opposite suspension side member. Ananti-roll bar is fitted between the trailing arms.The complete rear axle assembly is mountedonto the vehicle underbody via four rubbermountings.

The steering column has a universal jointfitted in the centre of its length, which isconnected to an intermediate shaft having asecond universal joint at its lower end. Thelower universal joint is clamped to the steeringgear pinion by means of a clamp bolt.

The steering gear is mounted onto the frontsubframe, and is connected by two trackrods, with balljoints at their outer ends, to thesteering arms projecting rearwards from theswivel hubs. The track rod ends are threaded,to facilitate adjustment.

Power-assisted steering is fitted asstandard on some models, and is available asan option on most others. The hydraulicpower steering system is powered by a belt-driven pump, which is driven off thecrankshaft pulley.

2 Front hub carrier assembly -removal and refitting 3

RemovalNote: All Nyloc nuts disturbed on removalmust be renewed as a matter of course. Thesenuts have threads which are pre-coated withlocking compound (this is only effective once).A balljoint separator tool will be required forthis operation.Note: Do not allow the vehicle to rest on itswheels with one or both driveshaftsdisconnected from the swivel hubs, asdamage to the wheel bearing(s) may result. Ifmoving the vehicle is unavoidable, temporarilyinsert the outer end of the driveshaft(s) in thehub(s) and tighten the hub nut(s).Note: It is recommended that a coil springcompressor tool is used during the removaland refitting of the hub carrier. The hub carrier

can be removed without a spring compressor,but because of the long length of the strutwith the spring in a released state, it is difficultto separate the hub carrier from the strut, andunacceptable strain could be exerted on thedriveshaft joint. Do not attempt to use a make-shift method of compressing the spring, asthere is a risk of component damage andpersonal injury.Note: Two different types of hub carrierassembly may be fitted, depending on model.The earlier hub carriers are solid. The later hubcarriers are hollow, and can be identified fromthe hole at the top of the assembly (seeillustration 2.19a). When refitting note thatthe torque wrench settings differ for the twotypes of hub carrier (see “Specifications”).Modified lower arms are fitted in conjunctionwith the later hub carriers, and the early andlate type components are not interchangeable- if components are renewed, make sure thatthe correct new parts are obtained.1 Chock the rear wheels, then firmly apply thehandbrake. Jack up the front of the vehicle,and support it on axle stands (see “Jackingand Vehicle Support”). Remove theappropriate front roadwheel.2 On models with ABS, remove the wheelsensor as described in Chapter 9.3 Remove the R-clip, and withdraw thelocking cap from the driveshaft retaining nut(see illustration).4 Refit at least two roadwheel bolts to thefront hub, and tighten them securely. Have anassistant firmly depress the brake pedal, toprevent the front hub from rotating, then using

a socket and extension bar, slacken andremove the driveshaft retaining nut.Alternatively, a tool can be fabricated fromtwo lengths of steel strip (one long, one short)and a nut and bolt; the nut and bolt formingthe pivot of a forked tool. Bolt the tool to thehub using two wheel bolts, and hold the toolto prevent the hub from rotating as thedriveshaft nut is undone.5 Unscrew the two bolts securing the brakecaliper/mounting bracket assembly to theswivel hub, and slide the caliper assembly offthe disc. Recover the mounting plate, whereapplicable. Using a piece of wire or string, tiethe caliper to the front suspension coil spring,to avoid placing any strain on the hydraulicbrake hose.6 Use chalk or paint to mark the relationshipof the disc to the hub, then remove thescrew(s) securing the brake disc to the hub,and remove the disc. If it is tight, lightly tap itsrear face with a hide or plastic mallet.7 Where applicable, slacken and remove thebolt securing the wiring/hose retainingbracket to the top of the hub carrier.8 To ease removal of the hub carrier, fitspring compressor tools to the coil spring onthe strut, in accordance with themanufacturer’s instructions, and lightlytighten the compressors. Note that the hubcarrier can be removed without using springcompressors, but difficulty may beencountered disconnecting hub carrier fromthe lower end of the strut.9 Unscrew the bolt securing the anti-roll bardrop link to the lower arm.

10 Slacken and partially unscrew the trackrod end nut (unscrew the nut as far as the endof the threads on the balljoint to preventdamage to the threads as the joint isreleased), then release the balljoint using aballjoint separator tool. Remove the nut.11 Similarly, slacken the lower balljoint nut(securing the hub carrier to the lower arm),then release the balljoint using a separatortool (see illustration). Remove the nut.12 Undo the nut and withdraw the hubcarrier-to-suspension strut clamp bolt, notingthat the bolt fits from the rear of the vehicle(see illustration).13 Where applicable, tighten the compressortools, and compress the spring sufficiently toenable the lower end of the strut to bedisconnected from the hub carrier.14 Insert a lever into the slot in the hubcarrier, and spread the slot until the hubcarrier can be released from the strut.

15 Free the hub carrier assembly from theend of the strut, then release it from the outerconstant velocity joint splines, and remove itfrom the vehicle. If necessary, tap the end ofthe driveshaft (using a soft-faced mallet) tofree it from the hub carrier. Support the free,outboard end of the driveshaft by suspendingit using wire or string - do not allow thedriveshaft to hang down under its own weight.

Refitting16 Where applicable, fit the springcompressor tools in position as duringremoval, ensure that the driveshaft outerconstant velocity joint and hub splines areclean, then slide the hub fully onto thedriveshaft splines.17 Slide the hub carrier assembly fully ontothe suspension strut, aligning the slot in thehub carrier with the lug on the base of thestrut. Also ensure that the stop boss on thestrut is in contact with the top surface of thehub carrier (see illustration). Release the toolused to spread the hub carrier slot.18 Insert the hub carrier-to-suspension strutclamp bolt from the rear side of the strut, thenfit a new nut to the clamp bolt, and tighten itto the specified torque.19 Two types of hub carrier may be fitted.The later type can be identified from the holeat the top of the assembly (see illustration).When refitting a later type hub carrier,proceed as follows.

a) After tightening the clamp bolt, measurethe gap between the hub carrier clamplugs (see illustration). The gap must notbe less than specified. If the gap is lessthan specified, proceed as follows.

b) Check the condition of the lower end ofthe strut. If the strut cylinder has beencrushed, the shock absorber will bedamaged, and the strut must be renewed.

c) If the strut is not damaged, but the gapbetween the clamp lugs is still less thanspecified, renew the hub carrier.

To spread the slot in the hubcarrier, engage an 8.0 mmAllen key or hexagon bit inthe slot, then turn the key/bitto spread the slot.

20 Align the balljoint with the lower arm, thenfit the balljoint nut, and tighten to the specifiedtorque.21 Engage the track rod balljoint in the hubcarrier, then fit a new retaining nut and tightenit to the specified torque.22 Refit the bolt securing the anti-roll bardrop link to the lower arm, and tighten to thespecified torque.23 Refit the brake disc to the hub, ensuringthat the marks made before removal arealigned, then refit the brake caliper/mountingbracket. Apply suitable locking fluid to thecaliper/mounting bracket bolts then, whereapplicable refit the mounting plate, ensuringthat the plate is fitted so that its bend curvesaway from the caliper body, and refit thebolts. Tighten the bolts to the specifiedtorque.24 Lubricate the inner face and threads ofthe driveshaft retaining nut with clean engineoil, and refit it to the end of the driveshaft. Usethe method employed on removal to preventthe hub from rotating, and tighten thedriveshaft retaining nut to the specified torque(see Chapter 8). Check that the hub rotatesfreely.25 Engage the locking cap with thedriveshaft nut so that one of its cut-outs isaligned with the driveshaft hole. Secure thecap with the R-clip.26 Where applicable, slacken and removethe spring compressor tools.27 Where applicable, refit the ABS wheelsensor as described in Chapter 9.28 Where applicable, refit the wiring retainingbracket to the top of the hub carrier, andtighten its retaining bolt securely. Ensure thatthe earth lead is in position beneath the bolt,where applicable.29 Refit the roadwheel, then lower thevehicle to the ground and tighten theroadwheel bolts to the specified torque.

3 Front hub bearings - renewal 4Note: The bearing is a sealed, pre-adjustedand pre-lubricated, double-row roller type,and is intended to last the car’s entire servicelife without maintenance or attention. Neverovertighten the driveshaft nut beyond thespecified torque wrench setting in an attemptto “adjust” the bearing.Note: A press will be required to dismantleand rebuild the assembly; if such a tool is notavailable, a large bench vice and spacers(such as large sockets) will serve as anadequate substitute. The bearing’s inner racesare an interference fit on the hub; if the innerrace remains on the hub when it is pressedout of the hub carrier, a knife-edged bearingpuller will be required to remove it.1 Remove the hub carrier assembly asdescribed in Section 2.2 Support the hub carrier securely on blocks

or in a vice. Using a tubular spacer whichbears only on the inner end of the hub flange,press the hub flange out of the bearing. If thebearing’s outboard inner race remains on thehub, remove it using a bearing puller (see noteabove).3 Extract the bearing retaining circlip from theinner end of the hub carrier assembly (seeillustration).4 Where necessary, refit the inner race backin position over the ball cage, and securelysupport the inner face of the hub carrier.Using a tubular spacer which bears only onthe inner race, press the complete bearingassembly out of the hub carrier.5 Thoroughly clean the hub and hub carrier,removing all traces of dirt and grease, andpolish away any burrs or raised edges whichmight hinder reassembly. Check both forcracks or any other signs of wear or damage,and renew them if necessary. Renew thecirclip, regardless of its apparent condition.6 On reassembly, apply a light film of oil tothe bearing outer race and hub flange shaft, toaid installation of the bearing.7 Securely support the hub carrier, and locatethe bearing in the hub. Press the bearing fullyinto position, ensuring that it enters the hubsquarely, using a tubular spacer which bearsonly on the bearing outer race.8 Once the bearing is correctly seated,secure the bearing in position with the newcirclip, ensuring that it is correctly located inthe groove in the hub carrier.9 Securely support the outer face of the hubflange, and locate the hub carrier bearinginner race over the end of the hub flange.

Press the bearing onto the hub, using atubular spacer which bears only on the innerrace of the hub bearing, until it seats againstthe hub shoulder. Check that the hub flangerotates freely, and wipe off any excess oil orgrease.10 Refit the hub carrier assembly asdescribed in Section 2.

4 Front suspension strut -removal and refitting 3

RemovalNote: All Nyloc nuts disturbed on removalmust be renewed as a matter of course. Thesenuts have threads which are pre-coated withlocking compound (this is only effective once).Note: It is recommended that a coil springcompressor tool is used during the removaland refitting of the strut. The strut can beremoved without a spring compressor, butbecause of the long length of the strut with thespring in a released state, it is difficult toseparate the hub carrier from the strut, andunacceptable strain could be exerted on thedriveshaft joint. Do not attempt to use a make-shift method of compressing the spring, asthere is a risk of component damage andpersonal injury.1 Chock the rear wheels, apply thehandbrake, then jack up the front of thevehicle and support on axle stands (see“Jacking and Vehicle Support”). Remove theappropriate roadwheel.2 Working in the engine compartment, wereapplicable remove the plastic cover from thestrut top mounting, then slacken but do notremove the two strut top mounting nuts (seeillustration).3 Where applicable, unclip any wiring and/orhoses from the strut.4 Unscrew the bolt securing the anti-roll bardrop link to the strut.5 Undo the nut and withdraw the hub carrier-to-suspension strut clamp bolt, noting that thebolt fits from the rear of the strut (seeillustration). Discard the nut - a new one mustbe used on refitting.6 To ease removal of the hub carrier, fit springcompressor tools to the coil spring on the strut,

in accordance with the manufacturer’sinstructions, and lightly tighten thecompressors. Note that the strut can beremoved without using spring compressors, butdifficulty may be encountered disconnectinghub carrier from the lower end of the strut.7 Insert a lever into the slot in the hub carrier,and spread the slot until the hub carrier canbe released from the strut.

8 Free the hub carrier from the strut, thenremove the two strut top mounting nuts, andwithdraw the strut from under the wheel arch.

Refitting9 Where applicable, fit the coil springcompressors as during removal, thenmanoeuvre the strut assembly into position.Feed the top mounting studs through theholes in the body, and fit the mounting nuts.10 Engage the lower end of the strut with thehub carrier. Align the slot in the hub carrierwith the lug on the base of the strut. Alsoensure that the stop bosses on the strut are incontact with the top surface of the hub carrier.Release the tool used to spread the hubcarrier slot.11 Insert the hub carrier-to-suspension strutclamp bolt from the rear side of the strut, thenfit a new nut to the clamp bolt, and tighten itto the specified torque.

12 Refit the bolt securing the anti-roll bardrop link to the strut.13 Tighten the two strut top mounting nuts tothe specified torque.14 Where applicable, carefully slacken andthen remove the spring compressors.15 Where applicable, clip any wiring/hosesinto position on the strut.16 Refit the roadwheel, then lower thevehicle to the ground and tighten theroadwheel bolts to the specified torque.

5 Front suspension strut -overhaul 3

Note: The components encountered may varyin detail, but the principles described in thefollowing paragraphs are equally applicable toall models. Make a careful note of the fittedpositions of all components beforedismantling.1 With the strut removed as described inSection 4, clean the exterior of the unit, thenmount it in a soft-jawed vice.

2 If not already done, fit coil springcompressors in accordance with themanufacturer’s instructions, and compressthe spring until the pressure on the topmounting is relieved.3 Unscrew the top mounting nut. Use a ringspanner to unscrew the nut, and counterholdthe piston rod using a 7.0 mm Allen key (seeillustration).4 Remove the nut and recover the washer,then lift off the cupped washer, mountingplate, rubber buffer, and the two dishedplates.5 Lift off the upper spring seat.6 Withdraw the washer and the rubber gaiter.7 Remove the bump stop.8 Remove the coil spring. If the spring is to berenewed, remove the compressors, otherwiseleave them in position for reassembly.9 Inspect the strut for signs of leakage fromthe piston rod seal. With the strut heldvertically, operate the piston over its full rangeof movement in both directions, checking thatthe resistance is even and firm. If theresistance is weak or jerky, if there is any fluidseepage, or if there is any damage to the strutor corrosion of the piston rod, then strut mustbe renewed. Note that struts should alwaysbe renewed in pairs. At the same time, checkthe coil spring for condition, and any signs ofdistortion or damage. If spring renewal isnecessary, again note that both front springsshould be renewed as a pair.10 Reassemble the strut using a reversal ofthe dismantling procedure, and following theaccompanying illustration sequence (seeillustrations 5.10a to 5.10l).

Warning: Before attempting todismantle the front suspensionstrut, a suitable tool to hold thecoil spring in compression must

be obtained. Adjustable coil springcompressors are readily-available, and arerecommended for this operation. Anyattempt to dismantle the strut withoutsuch a tool is likely to result in damage orpersonal injury.

6 Front suspension lower arm - removal, overhaul and refitting

4RemovalNote: All Nyloc nuts disturbed on removalmust be renewed as a matter of course. Thesenuts have threads which are pre-coated withlocking compound (this is only effective once).A balljoint separator tool will be required forthis operation.Note: Two different types of hub carrierassembly may be fitted, depending on model.The earlier hub carriers are solid. The later hubcarriers are hollow, and can be identified fromthe hole at the top of the assembly (seeillustration 2.19a). When refitting note thatthe torque wrench settings differ for the twotypes of hub carrier (see “Specifications”).Modified lower arms are fitted in conjunctionwith the later hub carriers, and the early andlate type components are not interchangeable

- if components are renewed, make sure thatthe correct new parts are obtained.1 Apply the handbrake, then jack up the frontof the vehicle and support on axle stands (see“Jacking and Vehicle Support”). Remove therelevant roadwheel.2 Remove the bolt securing the anti-roll bardrop link to the lower arm (see illustration).3 Slacken and partially unscrew the lowerballjoint nut (unscrew the nut as far as the endof the threads on the balljoint to preventdamage to the threads as the joint isreleased), then release the balljoint using aballjoint separator tool. Remove the nut.4 Counterhold the nut, and unscrew the lowerarm front pivot bolt (see illustration).Withdraw the bolt.5 Unscrew the two lower arm rear securingnuts (see illustration).6 Working at the rear of the subframe, loosenthe two subframe rear mounting bolts to allowthe rear of the subframe to be lowered

Overhaul8 Thoroughly clean the lower arm and thearea around the arm mountings, removing alltraces of dirt and underseal if necessary, thencheck carefully for cracks, distortion or anyother signs of wear or damage, payingparticular attention to the mounting bushes,and renew components as necessary.9 Examine the shank of the pivot bolt forsigns of wear or scoring, and renew ifnecessary.10 Examine the mounting bushes fordeterioration or damage.11 The mounting bushes can be renewed,but a press or suitable alternative tools will berequired. If the rear mounting bush isrenewed, it must be pressed into the positionshown, and the marks on the bush and thelower arm must be aligned. Note that somebushes have two alignment marks, in whichcase the mark nearest the bolt hole should beignored. Use a little silicon lubricant to aidfitting of the bushes (see illustrations).

Refitting12 Refitting is a reversal of removal, bearingin mind the following points.a) Renew all Nyloc nuts.b) Tighten all fixings to the specified torque.c) On completion, have the front wheel

alignment checked at the earliestopportunity with reference to Section 25.

RemovalNote: All Nyloc nuts disturbed on removalmust be renewed as a matter of course. Thesenuts have threads which are pre-coated withlocking compound (this is only effective once).Note: After refitting, the anti-roll baradjustment should be checked by a Peugeotdealer at the earliest opportunity (thesuspension must be compressed usingspecial equipment in order to carry out thecheck).1 Apply the handbrake, then jack up the frontof the vehicle and support on axle stands (see“Jacking and Vehicle Support”). Remove theroadwheels.2 Remove the bolts securing the anti-roll bardrop links to the lower arms.3 Unscrew the bolts securing the drop linksto the ends of the anti-roll bar, and withdrawthe drop links (see illustration). If necessary,counterhold the ends of the drop links using asuitable Allen key or hexagon bit.4 Make (horizontal) alignment marks betweenthe anti-roll bar and the clamps securing theanti-roll bar to the subframe, so that the anti-roll bar can be fitted in exactly the sameposition.5 Unscrew the clamp bolts, then withdrawthe clamp assemblies. Recover the spacers.Note that there is no need to remove themetal clamps (fitted on the bar, at the insideedges of the main clamps), which prevent theanti-roll bar from moving laterally (seeillustration).6 Manipulate the anti-roll bar out from underthe vehicle. Note that it may be necessary toloosen the two subframe rear mounting boltsto allow the rear of the subframe to belowered sufficiently to allow clearance toremove the anti-roll bar. Note that the

9 Front suspension subframe -removal and refitting 4

RemovalNote: All Nyloc nuts disturbed on removalmust be renewed as a matter of course. Thesenuts have threads which are pre-coated withlocking compound (this is only effective once).1 Apply the handbrake, then jack up the frontof the vehicle and support securely on axlestands (see “Jacking and Vehicle Support”).2 Remove the suspension lower arms asdescribed in Section 6.3 Remove the steering gear (see Section 19).4 Remove the rear engine mounting asdescribed in Chapter 2.5 Where applicable, release the clip securing theclutch cable to the subframe (see illustration).6 Where applicable, remove the screwsand/or clips securing the underbody shieldsand wheel arch liners to the subframe (seeillustration).7 Work around the subframe, and release anypipes, hoses and wiring from the clips andbrackets on the subframe. Note that it may be

necessary to disconnect certain componentson some models. Make a note of the routingof all pipes, hoses and wiring to ensurecorrect refitting.8 Support the subframe using a trolley jackand interposed block of wood. Make sure thatthe jack is positioned to adequately supportthe subframe without danger of the assemblyfalling off the jack.9 Unscrew the four subframe mounting bolts,and carefully lower the subframe from underthe vehicle (see illustration). Note that thesubframe rear mounting bolts may be coveredby plastic plugs on certain models.

Refitting10 From approximately November 1988,revised subframe rear mounting bolts wereintroduced. The later bolts incorporate acaptive washer in place of the Bellville washerfitted to earlier bolts. If the earlier Bellvillewashers are found to be cracked, the laterbolts with captive washers should be fitted. Itis advisable to take the opportunity to fit thelater type of bolts as a matter of course, toavoid possible problems in the future.11 From approximately mid-1992, thesubframe rear mountings were modified. Therear mounting bolts were increased in sizefrom M12 to M14, and torque wrench settingwas changed accordingly.12 Subframes with M14 bolts can beidentified from the 6.0 mm holes locatedbehind the rear mountings (see illustration).13 Body shells with fixings provided for theM14 bolts can be identified from the two

b) Refit the rear engine mounting withreference to Chapter 2.

c) Refit the steering gear (see Section 19).d) Refit the lower arms with reference to

Section 6.e) Tighten all fixings to the specified torque.

10 Rear hub assembly - removal and refitting 4

RemovalNote: Do not remove the hub assembly unlessit is absolutely necessary. A puller will be

required to draw the hub assembly off thestub axle, and the hub bearing will almostcertainly be damaged by the removalprocedure. A new oil seal support cup, and anew hub nut and hub cap will be required onrefitting.1 On models with rear disc brakes, removethe brake disc as described in Chapter 9.2 On models with rear drum brakes, removethe brake drum as described in Chapter 9. Ifdesired, to improve access for hub removal,also remove the brake shoes.3 Where applicable, remove the ABS wheelsensor as described in Chapter 9. Note thatthere is no need to disconnect the wiringconnector, but move the sensor to one side,clear of the working area.4 Using a hammer and a large flat-bladedscrewdriver, carefully tap and prise the capout of the centre of the hub.

Discard the hub nut - a new nutmust used on refitting.6 Using a puller, draw the hub assembly offthe stub axle, along with the outer bearingrace. With the hub removed, use the puller todraw the inner bearing race off the stub axle,then remove the oil seal support cup, notingwhich way around it is fitted (seeillustrations).7 Refit the races to the hub bearing, andcheck the hub bearing for signs of roughness.It is recommended that the bearing should berenewed as a matter of course, as it is likely tohave been damaged during removal. Thismeans that the complete hub assembly mustbe renewed, since it is not possible to obtainthe bearing separately.8 With the hub removed, examine the stubaxle shaft for signs of wear or damage. Thestub axle is integral with the trailing arms, andif damaged, the complete assembly must berenewed.

Refitting9 Lubricate the stub axle shaft with cleanengine oil, then slide on the new oil sealsupport cup, ensuring it is fitted the correctway round.10 Fit the new bearing inner race, and tap itfully onto the stub axle using a hammer and atubular drift which bears only on the flat insideedge of the race (see Tool Tip overleaf).

11 Ensure that the bearing is packed withgrease, then slide the hub assembly onto thestub axle. Fit the new outer bearing race, andtap it into position using a tubular drift until thehub nut can be fitted to finally draw the hubinto position (see illustrations).12 Fit the thrustwasher and new hub nut, andtighten the hub nut to the specified torque.Stake the nut firmly into the groove on thestub axle to secure it in position, then tap thenew hub cap into place in the centre of thehub (see illustrations).13 Refit the rear brake disc, or the brakedrum (and shoes, where applicable), asdescribed in Chapter 9.

11 Rear hub bearing - renewal

It is not possible to renew the rear hubbearing separately. If the bearing is worn, thecomplete rear hub assembly must berenewed. Refer to Section 10 for hub removaland refitting procedures.

12 Rear suspensioncomponents - general

1 Although it is possible to remove the rearsuspension torsion bars, trailing arms and

anti-roll bar independently of the completerear axle assembly, it is essential to havespecial tools available to complete the worksuccessfully (see illustration).2 Due to the complexity of the tasks, and therequirement for special tools to accurately setthe suspension geometry on refitting, theremoval and refitting of individual rearsuspension components is considered to bebeyond the scope of DIY work, and should beentrusted to a Peugeot dealer.3 Procedures for removal and refitting of therear shock absorbers, and the complete rearsuspension assembly are given in Sections 13and 14 respectively.

Testing5 Examine the shock absorber for signs offluid leakage or damage. Test the operation ofthe shock absorber, while holding it in anupright position, by moving the piston througha full stroke and then through short strokes of50 to 100 mm. In both cases, the resistancefelt should be smooth and continuous. If theresistance is jerky, or uneven, or if there is anyvisible sign of wear or damage, renewal isnecessary.6 Also check the rubber mounting bushes fordamage and deterioration. New bushes canbe fitted using a long bolt, nut and spacers todraw the bush into position. Lubricate the newbush with soapy water to aid fitting.7 Inspect the shanks of the mounting boltsfor signs of wear or damage, and renew asnecessary.

Refitting8 Prior to refitting the shock absorber, mountit upright in the vice, and operate it fullythrough several strokes in order to prime it.Apply a smear of multi-purpose grease toboth the shock absorber mounting bolts.9 Manoeuvre the shock absorber intoposition, and insert its mounting bolts (withwashers in place). Note that the bolts fit fromthe inside of the vehicle, ie the nuts fit on theroadwheel side of the shock absorber.10 Fit the washers and new nuts to themounting bolts, but do not tighten the fixingsat this stage.11 Measure the distance between the shockabsorber bolt centres, and load the vehicle (byadding weight to the luggage compartment)until a distance of 328.0 mm is obtainedbetween the bolt centres. Tighten the shockabsorber mounting nuts and bolts to thespecified torque.12 Drive the vehicle off the ramps.

14 Rear axle assembly - removal and refitting 4

RemovalNote: Before carrying out this procedure, it isadvisable to run the fuel tank as near empty aspossible to minimise the amount of fuel whichhas to be drained from the tank.1 Chock the front wheels, then jack up therear of the vehicle and support securely onaxle stands, until the trailing arms are atmaximum extension, with the roadwheels stillresting on the ground (see “Jacking andVehicle Support”).2 Where applicable, remove the rearunderbody shield.3 Remove the rear and intermediate exhaustsections as described in Chapter 4.4 Empty the fuel tank by either disconnectingthe filler pipe and draining, or by siphoning thefuel out through the filler neck. In either case,collect the fuel in a container which can besealed.5 Disconnect the fuel filler pipe from the tank(If not already done). Plug the open ends ofthe tank and the hose to prevent dirt ingress.6 Remove the rear exhaust heat shield fromthe underbody.7 Disconnect the handbrake cables from theadjuster mechanism under the rearunderbody, with reference to Chapter 9.8 Release the handbrake cables from anyclips and brackets, and move them clear ofthe suspension components to facilitateremoval.9 Loosen the fuel tank support strap bolts asfar as possible without removing them, andlower the fuel tank.10 Disconnect the brake fluid pipes at theunions on the rear suspension assembly, withreference to Chapter 9. Plug the open ends ofthe unions.11 On models with a load-sensitive rearbrake pressure regulating valve, disconnectthe hydraulic pipes at the valve. Again, plugthe opens ends of the pipes and the valve.12 Where applicable, remove the rear ABSwheel sensors. Note that there is no need to

disconnect the wiring connectors, but unclipthe wiring harnesses from the rear suspensioncomponents, and move the sensors to oneside, clear of the working area.13 Place a trolley jack under the rearsuspension tubular crossmember to supportthe suspension assembly.14 Make a final check to ensure that allrelevant pipes and wires have beendisconnected to facilitate removal of thesuspension assembly.15 Using a long-reach splined adapter,unscrew the suspension assembly rearsecuring bolts, accessible through the holesin the suspension assembly side members(see illustration).16 Working at the front of the suspensionassembly, unscrew the two bolts on each sidesecuring the front mountings to theunderbody (see illustration).17 Lower the trolley jack slightly, and pull thesuspension rearwards. If necessary, raise thevehicle body in order for the suspension toclear the fuel tank, then withdraw thesuspension assembly from under the vehicle.

Refitting18 Refitting is a reversal of the removalprocedure, bearing in mind the followingpoints.a) Tighten all fixings to the specified torque.b) Bleed the brake hydraulic system as

described in Chapter 9.c) Adjust the handbrake mechanism as

described in Chapter 9.d) On completion, have the rear ride height

checked by a Peugeot dealer.

15 Vehicle ride height - checking 5Checking of the vehicle ride height requires

the use of Peugeot special tools to accuratelycompress the suspension in a suspensionchecking bay.

The operation should be entrusted to aPeugeot dealer, as it not possible to carry outchecking accurately without the use of theappropriate tools.

Warning: Refer to theprecautions given in Chapter 12,Section 24 before proceeding.Note that the air bag control

module is integral with the steering wheel.Additionally, note the following points.

Inspection14 The steering column incorporates atelescopic safety feature. In the event of afront-end crash, the shaft collapses andprevents the steering wheel injuring the driver.Before refitting the steering column, examinethe column and mountings for signs ofdamage and deformation, and renew asnecessary.15 Check the steering column shaft for signsof free play in the column bushes, and checkthe universal joint for signs of damage orroughness in the joint bearings. If any damageor wear is found on the steering columnuniversal joint or shaft bushes, the columnmust be renewed as an assembly.16 Similarly, where applicable, examine theintermediate shaft and renew if the universaljoint is worn.17 If Nyloc-type nuts were used to secure thesteering column, these must be renewed as amatter of course.

Refitting18 Refitting is a reversal of removal, bearingin mind the following points.19 If the intermediate shaft has beenremoved, make sure that the bulkheadgrommet is not dislodged on refitting.20 Align the marks made on the intermediateshaft and the steering column shaft beforeremoval.21 On models fitted with an air bag, do nottighten the column shaft pinch-bolt or refit thetrim panel until the procedure given inparagraph 27 has been carried out.22 Ensure that the column height adjusterlever is in the released position when thecolumn securing nuts/bolts are refitted.23 Renew any Nyloc nuts.24 Tighten all fixings to the specified torque.25 Refit the steering wheel as described inSection 16.26 Where applicable, refit the air bag asdescribed in Chapter 12.27 On models with an air bag, on completion,carry out the following procedure.a) Move the steering column to its fully

raised position, then check that theclearance between the rear face of thesteering wheel and the front faces of the

steering column shrouds is 8.0 mm. If theclearance is not as specified, proceed asfollows.

b) Loosen the steering column shaft-to-intermediate shaft pinch-bolt, then slidethe steering shaft as necessary to give thespecified clearance between the steeringwheel and the shrouds.

c) Tighten the pinch-bolt, and refit the trimpanel.

18 Ignition switch/steeringcolumn lock - removal andrefitting

3Removal1 Disconnect the battery negative lead.2 Remove the steering column shrouds asdescribed in Chapter 11.3 Working under the steering column, locatethe three ignition switch wiring connectors,and separate the two halves of eachconnector. Unclip the connectors from thebracket, and release the wiring harness fromany clips.4 Insert the ignition key and turn it to alignwith the small arrow on the lock rim.5 Unscrew the lock securing screw (seeillustration).6 Using a small screwdriver, depress the lockretaining lug, whilst simultaneously pulling thelock from the housing using the key (seeillustration).7 Withdraw the lock assembly, feeding thewiring up through the steering column tube.

8 To separate the ignition switch from thelock, proceed as follows.a) Remove the two securing screws from the

rear of the lock (see illustration).b) Slide the rear section from the lock body

(see illustration).c) Slide the ignition switch unit from the lock

body (see illustration).

Refitting9 When refitting the ignition switch to thelock, first ensure that the ignition key isremoved from the lock, and ensure that theswitch wiper is turned anti-clockwise as far aspossible. Check that the lugs on the wiperengage with the cut-outs in the lock body.10 Refit the lock using a reversal of theremoval procedure.

19 Steering gear assembly -removal, overhaul and refitting 3

RemovalNote: All Nyloc nuts disturbed on removalmust be renewed as a matter of course. Thesenuts have threads which are pre-coated withlocking compound (this is only effective once).1 Disconnect the battery negative lead.2 Apply the handbrake, then jack up the frontof the vehicle and support securely on axlestands (see “Jacking and Vehicle Support”).Remove the roadwheels.3 If desired, to improve access, remove thewheel arch liners, referring to Chapter 11.

4 On models with power steering, drain thehydraulic fluid as follows.a) Remove the cap from the fluid reservoir.b) Place a container under the high pressure

fluid pipe union on the steering gear, thenunscrew the union.

c) Allow the fluid to drain into the container.d) Turn the steering from lock-to-lock

several times to completely drain thesystem.

e) Disconnect the low pressure hose fromthe steering gear.

5 Where applicable, unbolt the heat shieldfrom the steering gear.6 On manual gearbox models, prise the capfrom the gear linkage pivot, then unscrew thelinkage pivot bolt. Move the gear linkage clearof the steering gear, and tie it up out of theway using wire or string.7 Make alignment marks between the end ofthe intermediate shaft and the steering gearpinion, then unscrew the clamp bolt securingthe intermediate shaft universal joint to thepinion.8 Working on one side of the vehicle, slackenand partially unscrew the track rod end nut(unscrew the nut as far as the end of thethreads on the balljoint to prevent damage tothe threads as the joint is released), thenrelease the balljoint using a balljoint separatortool (see illustration). Remove the nut.9 Repeat the procedure on the remaining sideof the vehicle.10 Unscrew the two bolts securing thesteering gear to the subframe. Recover thewashers, and spacers, taking careful note oftheir positions to ensure correct refitting.11 Rotate the steering gear around itshorizontal axis, so that the pinion is at thebottom, then withdraw the assembly fromunder the right-hand wheel arch.

Overhaul12 Examine the steering gear assembly forsigns of wear or damage, and check that therack moves freely throughout the full length ofits travel, with no signs of roughness orexcessive free play between the steering gearpinion and rack. It is possible to overhaul thesteering gear assembly housing components,but this task should be entrusted to a Peugeotdealer. The only components which can berenewed easily by the home mechanic are the

steering gear gaiters, the track rod balljointsand the track rods. Track rod, track rodballjoint and steering gear gaiter renewalprocedures are covered in Sections 24, 23and 20 respectively.13 On models with power steering, inspectall the steering gear fluid unions for signs ofleakage, and check that all union nuts aresecurely tightened. Also examine the steeringgear hydraulic ram for signs of fluid leakage ordamage, and if necessary renew it.

RefittingNote: There have been a number ofmodifications to the steering gear and thesubframe, which alter the dimension of thesteering gear-to-subframe mounting points.Different thicknesses of spacer are fittedbetween the rack and the subframe, andunder the mounting bolt heads. Due to themany combinations of different components,and the non-interchangeability of the differentcomponents, if either the steering gear orsubframe are to be renewed, the advice of aPeugeot dealer should be sought.14 Refitting is a reversal of removal, bearingin mind the following points.a) Use new nuts when reconnecting the

track rod ends.b) Tighten all fixings to the specified torque.c) On models with power steering, fill and

bleed the hydraulic system as describedin Section 21.

d) On completion, have the front wheelalignment checked at the earliestopportunity.

20 Steering gear rubber gaiters - renewal 4

Manual steering gear1 Remove the track rod balljoint as describedin Section 23.2 Mark the correct fitted position of the gaiteron the track rod, then release the retainingclips and slide the gaiter off the steering gearhousing and track rod end.3 Thoroughly clean the track rod and thesteering gear housing, using fine abrasivepaper to polish off any corrosion, burrs orsharp edges, which might damage the newgaiter’s sealing lips on installation. Scrape offall the grease from the old gaiter, and apply itto the track rod inner balljoint. (This assumesthat grease has not been lost or contaminatedas a result of damage to the old gaiter. Usefresh grease if in doubt.)4 Carefully slide the new gaiter onto the trackrod end, and locate it on the steering gearhousing. Align the outer edge of the gaiterwith the mark made on the track rod prior toremoval, then secure it in position with newretaining clips.5 Refit the track rod balljoint as described inSection 23.

Power-assisted steering gear6 On power-assisted steering gear assem-blies, it is only possible to renew the gaiternearest the drive pinion, ie the right-handgaiter on right-hand-drive models, and theleft-hand gaiter on left-hand-drive models.This can be renewed as described above inparagraphs 1 to 5.7 The task of renewing the opposite gaitershould be entrusted to a Peugeot dealer. Thisis necessary since it is not possible to passthe gaiter over the steering rack stud to whichthe hydraulic ram is fixed. Therefore, thesteering gear must be dismantled and therack removed from the housing to allow thegaiter to be renewed.8 The only task on this end of the assemblywhich can be carried out by the homemechanic is the renewal of the track rod innerballjoint dust cover. The dust cover can berenewed once the track rod balljoint has beenremoved as described in Section 23. Onrefitting, ensure that the dust cover iscorrectly located on the track rod and steeringrack, then refit the balljoint.

21 Power steering system -bleeding 2

1 This procedure will only be necessary whenany part of the hydraulic system has beendisconnected.2 Referring to Chapter 1, remove the fluidreservoir filler cap, and top-up with thespecified fluid to the maximum level mark.3 With the engine stopped, slowly move thesteering from lock-to-lock several times topurge out the trapped air, then top-up thelevel in the fluid reservoir. Repeat thisprocedure until the fluid level in the reservoirdoes not drop any further.4 Start the engine, then slowly move thesteering from lock-to-lock several times topurge out any remaining air in the system.Repeat this procedure until bubbles cease toappear in the fluid reservoir.5 If, when turning the steering, an abnormalnoise is heard from the fluid lines, it indicatesthat there is still air in the system. Check thisby turning the wheels to the straight-aheadposition and switching off the engine. If thefluid level in the reservoir rises, then air ispresent in the system, and further bleeding isnecessary.6 Once all traces of air have been removedfrom the power steering hydraulic system,turn the engine off and allow the system tocool. Once cool, check that fluid level is up tothe maximum mark on the power steeringfluid reservoir, topping-up if necessary (referto “Weekly Checks” if necessary).

23 Track rod end - removal and refitting 3

RemovalNote: A new track rod end-to-hub carrier nutmust be used on refitting.1 Apply the handbrake, then jack up the frontof the vehicle and support it on axle stands(see “Jacking and Vehicle Support”). Removethe appropriate front roadwheel.2 If the balljoint is to be re-used, use astraight-edge and a scriber, or similar, to markits relationship to the track rod.

3 Hold the track rod, and unscrew the trackrod end locknut by a quarter of a turn. Do notmove the locknut from this position, as it willserve as a handy reference mark on refitting(see illustration).4 Slacken and partially unscrew the track rodend-to-hub carrier nut (unscrew the nut as faras the end of the threads on the balljoint toprevent damage to the threads as the joint isreleased), then release the balljoint using aballjoint separator tool (see illustration).Remove the nut.5 Counting the exact number of turnsnecessary to do so, unscrew the track rodend from the track rod.6 Count the number of exposed threadsbetween the end of the track rod end and thelocknut, and record this figure. If a new trackrod end is to be fitted, unscrew the locknutfrom the old track rod end.7 Carefully clean the balljoint and the threads.Renew the track rod end if its balljointmovement is sloppy or too stiff, if excessivelyworn, or if damaged in any way; carefullycheck the stud taper and threads. If theballjoint gaiter is damaged, the complete trackrod end assembly must be renewed; it is notpossible to obtain the gaiter separately.

Refitting8 If a new track rod end is to be fitted, screwthe locknut onto its threads, and position it so

that the same number of exposed threads arevisible, as were noted prior to removal.9 Screw the track rod end onto the track rodby the number of turns noted on removal. Thisshould bring the locknut to within a quarter ofa turn of the end face of the track rod, with thealignment marks that were made on removal(if applicable) lined up.10 Engage the balljoint taper with the hubcarrier, then fit a new retaining nut and tightenit to the specified torque.11 Refit the roadwheel, then lower thevehicle to the ground and tighten theroadwheel bolts to the specified torque.12 Check and, if necessary, adjust the frontwheel toe setting as described in Section 25,then securely tighten the track rod endlocknut.

24 Track rod - removal and refitting 4

RemovalNote: A new inner balljoint lockwasher mustbe used on refitting.1 Remove the track rod end as described inSection 23.2 Either release the retaining clips and slidethe steering gear gaiter off the end of the trackrod, or release the track rod balljoint dustcover from rack, and slide it off the track rod(as applicable). Refer to Section 20 for furtherinformation.3 Unscrew the track rod inner balljoint fromthe steering rack end, preventing the steeringrack from turning by holding the balljoint lockwasher with a pair of grips. Take great carenot to mark the surfaces of the rack andballjoint.4 Remove the track rod assembly, anddiscard the lock washer - a new one must beused on refitting.5 Examine the track rod inner balljoint forsigns of slackness or tight spots, and checkthat the track rod itself is straight and freefrom damage. If necessary, renew the trackrod; it is also recommended that the steeringgear gaiter/dust cover is renewed.

Refitting6 Locate the new lock washer assembly onthe end of the steering rack, and apply a fewdrops of locking fluid to the track rod innerballjoint threads.7 Screw the balljoint into the steering rack,and tighten it whilst retaining the lock washerwith a pair of grips. Again, take great care notto damage or mark the track rod balljoint orsteering rack.8 Where a gaiter was removed, carefully slideon the new gaiter, and locate it on the steeringgear housing. Turn the steering fully fromlock-to-lock, to check that the gaiter iscorrectly positioned on the track rod, thensecure it in position with new retaining clips.

25 Wheel alignment andsteering angles - generalinformation

General1 A car’s steering and suspension geometryis defined in four basic settings - all angles areexpressed in degrees (toe settings are alsoexpressed as a measurement); the relevantsettings are camber, castor, steering axisinclination, and toe-setting. With theexception of front wheel toe-setting, none ofthese settings are adjustable.

Front wheel toe setting -checking and adjustment2 Due to the special measuring equipmentnecessary to accurately check the wheelalignment, and the skill required to use itproperly, checking and adjustment is best leftto a Peugeot dealer or similar expert. Notethat most tyre-fitting shops now possesssophisticated checking equipment. Thefollowing is provided as a guide, should theowner decide to carry out a DIY check.3 The front wheel toe setting is checked bymeasuring the distance between the front andrear inside edges of the roadwheel rims.Proprietary toe measurement gauges areavailable from motor accessory shops.Adjustment is made by screwing the balljointsin or out of their track rods, to alter theeffective length of the track rod assemblies.4 For accurate checking, the vehicle must beat the kerb weight, ie unladen and with a full

tank of fuel, and the ride height must becorrect (see Section 15). Particularly note thatthe suspension must be compressed to theappropriate reference height. Accuratechecking and adjustment must be entrustedto a Peugeot dealer. The following informationis provided for reference only.5 Before starting work, check first that thetyre sizes and types are as specified, thencheck the tyre pressures and tread wear, theroadwheel run-out, the condition of the hubbearings, the steering wheel free play, and thecondition of the front suspension components(Chapter 1). Correct any faults found.6 Park the vehicle on level ground, check thatthe front roadwheels are in the straight-aheadposition, then rock the rear and front ends tosettle the suspension. Release the handbrake,and roll the vehicle backwards 1 metre, thenforwards again, to relieve any stresses in thesteering and suspension components.7 Measure the distance between the frontedges of the wheel rims and the rear edges ofthe rims. Subtract the rear measurement fromthe front measurement, and check that theresult is within the specified range.8 If adjustment is necessary, apply thehandbrake, then jack up the front of thevehicle and support it securely on axle stands.Turn the steering wheel onto full-left lock, andrecord the number of exposed threads on theright-hand track rod end. Now turn thesteering onto full-right lock, and record thenumber of threads on the left-hand side. Ifthere are the same number of threads visibleon both sides, then subsequent adjustmentshould be made equally on both sides. If thereare more threads visible on one side than theother, it will be necessary to compensate forthis during adjustment. Note: It is mostimportant that after adjustment, the same

number of threads are visible on each trackrod end.9 First clean the track rod end threads; if theyare corroded, apply penetrating fluid beforestarting adjustment. Release the rubber gaiteroutboard clips (where necessary), and peelback the gaiters; apply a smear of grease tothe inside of the gaiters, so that both are free,and will not be twisted or strained as theirrespective track rods are rotated.10 Use a straight-edge and a scriber orsimilar to mark the relationship of each trackrod to its track rod end then, holding eachtrack rod in turn, unscrew its locknut fully.11 Alter the length of the track rods, bearingin mind the note made in paragraph 8. Screwthem into or out of the track rod ends, rotatingthe track rod using an open-ended spannerfitted to the flats provided. Shortening thetrack rods (screwing them into their balljoints)will reduce toe-in/increase toe-out.12 When the setting is correct, hold the trackrods and securely tighten the track rod endlocknuts. Check that the balljoints are seatedcorrectly in their sockets, and count theexposed threads to check the length of bothtrack rods. If they are not the same, then theadjustment has not been made equally, andproblems will be encountered with tyrescrubbing in turns; also, the steering wheelspokes will no longer be horizontal when thewheels are in the straight-ahead position.13 If the track rod lengths are the same,lower the vehicle to the ground and re-checkthe toe setting; re-adjust if necessary. Whenthe setting is correct, securely tighten thetrack rod end locknuts. Ensure that the rubbergaiters are seated correctly, and are nottwisted or strained, and secure them inposition with new retaining clips (wherenecessary).

1 General information

The bodyshell is made of pressed steelsections, and is available in 4-door Saloonand 5-door Estate configuration. Mostcomponents are welded together, but someuse is made of structural adhesives. The frontwings are bolted on.

The bonnet, doors and some othervulnerable panels are made of zinc-coatedmetal, and are further protected by beingcoated with an anti-chip primer prior to beingsprayed.

Extensive use is made of plastic materials,mainly in the interior, but also in exteriorcomponents. The front and rear bumpers andthe front grille are injection-moulded from asynthetic material which is very strong, andyet light. Plastic components such as wheelarch liners are fitted to the underside of thevehicle, to improve the body’s resistance tocorrosion.

2 Maintenance -bodywork and underframe 1

The general condition of a vehicle’sbodywork is the one thing that significantly

affects its value. Maintenance is easy, butneeds to be regular. Neglect, particularly afterminor damage, can lead quickly to furtherdeterioration and costly repair bills. It isimportant also to keep watch on those partsof the vehicle not immediately visible, forinstance the underside, inside all the wheelarches, and the lower part of the enginecompartment.

The basic maintenance routine for thebodywork is washing - preferably with a lot ofwater, from a hose. This will remove all theloose solids which may have stuck to thevehicle. It is important to flush these off insuch a way as to prevent grit from scratchingthe finish. The wheel arches and underframeneed washing in the same way, to remove anyaccumulated mud which will retain moistureand tend to encourage rust. Strangelyenough, the best time to clean the underframeand wheel arches is in wet weather, when themud is thoroughly wet and soft. In very wetweather, the underframe is usually cleaned oflarge accumulations automatically, and this isa good time for inspection.

Periodically, except on vehicles with a wax-based underbody protective coating, it is agood idea to have the whole of theunderframe of the vehicle steam-cleaned,engine compartment included, so that athorough inspection can be carried out to seewhat minor repairs and renovations arenecessary. Steam-cleaning is available at

many garages, and is necessary for theremoval of the accumulation of oily grime,which sometimes is allowed to become thickin certain areas. If steam-cleaning facilities arenot available, there are one or two excellentgrease solvents available, which can bebrush-applied; the dirt can then be simplyhosed off. Note that these methods shouldnot be used on vehicles with wax-basedunderbody protective coating, or the coatingwill be removed. Such vehicles should beinspected annually, preferably just prior toWinter, when the underbody should bewashed down, and any damage to the waxcoating repaired. Ideally, a completely freshcoat should be applied. It would also be worthconsidering the use of such wax-basedprotection for injection into door panels, sills,box sections, etc, as an additional safeguardagainst rust damage, where such protection isnot provided by the vehicle manufacturer.

After washing paintwork, wipe off with achamois leather to give an unspotted clearfinish. A coat of clear protective wax polishwill give added protection against chemicalpollutants in the air. If the paintwork sheenhas dulled or oxidised, use a cleaner/polishercombination to restore the brilliance of theshine. This requires a little effort, but suchdulling is usually caused because regularwashing has been neglected. Care needs tobe taken with metallic paintwork, as specialnon-abrasive cleaner/polisher is required to

avoid damage to the finish. Always check thatthe door and ventilator opening drain holesand pipes are completely clear, so that watercan be drained out. Brightwork should betreated in the same way as paintwork.Windscreens and windows can be kept clearof the smeary film which often appears, by theuse of proprietary glass cleaner. Never useany form of wax or other body or chromiumpolish on glass.

3 Maintenance - upholstery and carpets 1

Mats and carpets should be brushed orvacuum-cleaned regularly, to keep them freeof grit. If they are badly stained, remove themfrom the vehicle for scrubbing or sponging,and make quite sure they are dry beforerefitting. Seats and interior trim panels can bekept clean by wiping with a damp cloth. If theydo become stained (which can be moreapparent on light-coloured upholstery), use alittle liquid detergent and a soft nail brush toscour the grime out of the grain of thematerial. Do not forget to keep the headliningclean in the same way as the upholstery.When using liquid cleaners inside the vehicle,do not over-wet the surfaces being cleaned.Excessive damp could get into the seams andpadded interior, causing stains, offensiveodours or even rot. If the inside of the vehiclegets wet accidentally, it is worthwhile takingsome trouble to dry it out properly, particularlywhere carpets are involved. Do not leave oil orelectric heaters inside the vehicle for thispurpose.

4 Minor body damage - repair 2Repairs of minor scratches in bodywork

If the scratch is very superficial, and doesnot penetrate to the metal of the bodywork,repair is very simple. Lightly rub the area ofthe scratch with a paintwork renovator, or avery fine cutting paste, to remove loose paintfrom the scratch, and to clear the surroundingbodywork of wax polish. Rinse the area withclean water.

Apply touch-up paint to the scratch using afine paint brush; continue to apply fine layersof paint until the surface of the paint in thescratch is level with the surroundingpaintwork. Allow the new paint at least twoweeks to harden, then blend it into thesurrounding paintwork by rubbing the scratcharea with a paintwork renovator or a very finecutting paste. Finally, apply wax polish.

Where the scratch has penetrated rightthrough to the metal of the bodywork, causingthe metal to rust, a different repair technique

is required. Remove any loose rust from thebottom of the scratch with a penknife, thenapply rust-inhibiting paint, to prevent theformation of rust in the future. Using a rubberor nylon applicator, fill the scratch withbodystopper paste. If required, this paste canbe mixed with cellulose thinners, to provide avery thin paste which is ideal for filling narrowscratches. Before the stopper-paste in thescratch hardens, wrap a piece of smoothcotton rag around the top of a finger. Dip thefinger in cellulose thinners, and quickly sweepit across the surface of the stopper-paste inthe scratch; this will ensure that the surface ofthe stopper-paste is slightly hollowed. Thescratch can now be painted over as describedearlier in this Section.

Repairs of dents in bodyworkWhen deep denting of the vehicle’s

bodywork has taken place, the first task is topull the dent out, until the affected bodyworkalmost attains its original shape. There is littlepoint in trying to restore the original shapecompletely, as the metal in the damaged areawill have stretched on impact, and cannot bereshaped fully to its original contour. It isbetter to bring the level of the dent up to apoint which is about 3 mm below the level ofthe surrounding bodywork. In cases where thedent is very shallow anyway, it is not worthtrying to pull it out at all. If the underside of thedent is accessible, it can be hammered outgently from behind, using a mallet with awooden or plastic head. Whilst doing this,hold a suitable block of wood firmly againstthe outside of the panel, to absorb the impactfrom the hammer blows and thus prevent alarge area of the bodywork from being“belled-out”.

Should the dent be in a section of thebodywork which has a double skin, or someother factor making it inaccessible frombehind, a different technique is called for. Drillseveral small holes through the metal insidethe area - particularly in the deeper section.Then screw long self-tapping screws into theholes, just sufficiently for them to gain a goodpurchase in the metal. Now the dent can bepulled out by pulling on the protruding headsof the screws with a pair of pliers.

The next stage of the repair is the removalof the paint from the damaged area, and froman inch or so of the surrounding “sound”bodywork. This is accomplished most easilyby using a wire brush or abrasive pad on apower drill, although it can be done just aseffectively by hand, using sheets of abrasivepaper. To complete the preparation for filling,score the surface of the bare metal with ascrewdriver or the tang of a file, oralternatively, drill small holes in the affectedarea. This will provide a really good “key” forthe filler paste.

To complete the repair, see the Section onfilling and respraying.

Repairs of rust holes or gashes in bodywork

Remove all paint from the affected area,and from an inch or so of the surrounding“sound” bodywork, using an abrasive pad or awire brush on a power drill. If these are notavailable, a few sheets of abrasive paper willdo the job most effectively. With the paintremoved, you will be able to judge the severityof the corrosion, and therefore decidewhether to renew the whole panel (if this ispossible) or to repair the affected area. Newbody panels are not as expensive as mostpeople think, and it is often quicker and moresatisfactory to fit a new panel than to attemptto repair large areas of corrosion.

Remove all fittings from the affected area,except those which will act as a guide to theoriginal shape of the damaged bodywork (egheadlamp shells etc). Then, using tin snips ora hacksaw blade, remove all loose metal andany other metal badly affected by corrosion.Hammer the edges of the hole inwards, inorder to create a slight depression for the fillerpaste.

Wire-brush the affected area to remove thepowdery rust from the surface of theremaining metal. Paint the affected area withrust-inhibiting paint; if the back of the rustedarea is accessible, treat this also.

Before filling can take place, it will benecessary to block the hole in some way. Thiscan be achieved by the use of aluminium orplastic mesh, or aluminium tape.

Aluminium or plastic mesh, or glass-fibrematting is probably the best material to usefor a large hole. Cut a piece to theapproximate size and shape of the hole to befilled, then position it in the hole so that itsedges are below the level of the surroundingbodywork. It can be retained in position byseveral blobs of filler paste around itsperiphery.

Aluminium tape should be used for small orvery narrow holes. Pull a piece off the roll, trimit to the approximate size and shape required,then pull off the backing paper (if used) andstick the tape over the hole; it can beoverlapped if the thickness of one piece isinsufficient. Burnish down the edges of thetape with the handle of a screwdriver orsimilar, to ensure that the tape is securelyattached to the metal underneath.

Bodywork repairs - filling and respraying

Before using this Section, see the Sectionson dent, deep scratch, rust holes and gashrepairs.

Many types of bodyfiller are available, butgenerally speaking, those proprietary kitswhich contain a tin of filler paste and a tube ofresin hardener are best for this type of repair.A wide, flexible plastic or nylon applicator willbe found invaluable for imparting a smoothand well-contoured finish to the surface of thefiller.

11•2 Bodywork and fittings

Mix up a little filler on a clean piece of cardor board - measure the hardener carefully(follow the maker’s instructions on the pack),otherwise the filler will set too rapidly or tooslowly. Using the applicator, apply the fillerpaste to the prepared area; draw theapplicator across the surface of the filler toachieve the correct contour and to level thesurface. As soon as a contour thatapproximates to the correct one is achieved,stop working the paste - if you carry on toolong, the paste will become sticky and beginto “pick-up” on the applicator. Continue toadd thin layers of filler paste at 20-minuteintervals, until the level of the filler is justproud of the surrounding bodywork.

Once the filler has hardened, the excesscan be removed using a metal plane or file.From then on, progressively-finer grades ofabrasive paper should be used, starting with a40-grade production paper, and finishing witha 400-grade wet-and-dry paper. Always wrapthe abrasive paper around a flat rubber, cork,or wooden block - otherwise the surface ofthe filler will not be completely flat. During thesmoothing of the filler surface, the wet-and-dry paper should be periodically rinsed inwater. This will ensure that a very smoothfinish is imparted to the filler at the final stage.

At this stage, the “dent” should besurrounded by a ring of bare metal, which inturn should be encircled by the finely“feathered” edge of the good paintwork.Rinse the repair area with clean water, until allof the dust produced by the rubbing-downoperation has gone.

Spray the whole area with a light coat ofprimer - this will show up any imperfections inthe surface of the filler. Repair theseimperfections with fresh filler paste orbodystopper, and once more smooth thesurface with abrasive paper. If bodystopper isused, it can be mixed with cellulose thinners,to form a really thin paste which is ideal forfilling small holes. Repeat this spray-and-repair procedure until you are satisfied thatthe surface of the filler, and the featherededge of the paintwork, are perfect. Clean therepair area with clean water, and allow to dryfully.

The repair area is now ready for finalspraying. Paint spraying must be carried outin a warm, dry, windless and dust-freeatmosphere. This condition can be createdartificially if you have access to a large indoorworking area, but if you are forced to work inthe open, you will have to pick your day verycarefully. If you are working indoors, dousingthe floor in the work area with water will helpto settle the dust which would otherwise be inthe atmosphere. If the repair area is confinedto one body panel, mask off the surroundingpanels; this will help to minimise the effects ofa slight mis-match in paint colours. Bodyworkfittings (eg chrome strips, door handles etc)will also need to be masked off. Use genuinemasking tape, and several thicknesses ofnewspaper, for the masking operations.

Before commencing to spray, agitate theaerosol can thoroughly, then spray a test area(an old tin, or similar) until the technique ismastered. Cover the repair area with a thickcoat of primer; the thickness should be builtup using several thin layers of paint, ratherthan one thick one. Using 400 grade wet-and-dry paper, rub down the surface of the primeruntil it is really smooth. While doing this, thework area should be thoroughly doused withwater, and the wet-and-dry paper periodicallyrinsed in water. Allow to dry before sprayingon more paint.

Spray on the top coat, again building up thethickness by using several thin layers of paint.Start spraying in the centre of the repair area,and then, using a circular motion, workoutwards until the whole repair area andabout 2 inches of the surrounding originalpaintwork is covered. Remove all maskingmaterial 10 to 15 minutes after spraying onthe final coat of paint.

Allow the new paint at least two weeks toharden, then, using a paintwork renovator or avery fine cutting paste, blend the edges of thepaint into the existing paintwork. Finally, applywax polish.

Plastic componentsWith the use of more and more plastic body

components by the vehicle manufacturers (egbumpers. spoilers, and in some cases majorbody panels), rectification of more seriousdamage to such items has become a matterof either entrusting repair work to a specialistin this field, or renewing completecomponents. Repair of such damage by theDIY owner is not really feasible, owing to thecost of the equipment and materials requiredfor effecting such repairs. The basic techniqueinvolves making a groove along the line of thecrack in the plastic, using a rotary burr in apower drill. The damaged part is then weldedback together, using a hot air gun to heat upand fuse a plastic filler rod into the groove.Any excess plastic is then removed, and thearea rubbed down to a smooth finish. It isimportant that a filler rod of the correct plasticis used, as body components can be made ofa variety of different types (eg polycarbonate,ABS, polypropylene).

Damage of a less serious nature (abrasions,minor cracks etc) can be repaired by the DIYowner using a two-part epoxy filler repair.Once mixed in equal parts, this is used insimilar fashion to the bodywork filler used onmetal panels. The filler is usually cured intwenty to thirty minutes, ready for sandingand painting.

If the owner is renewing a completecomponent himself, or if he has repaired itwith epoxy filler, he will be left with theproblem of finding a suitable paint for finishingwhich is compatible with the type of plasticused. At one time, the use of a universal paintwas not possible, owing to the complex rangeof plastics encountered in body componentapplications. Standard paints, generally

speaking, will not bond to plastic or rubbersatisfactorily, but suitable paints to match anyplastic or rubber finish, can be obtained fromdealers. However, it is now possible to obtaina plastic body parts finishing kit whichconsists of a pre-primer treatment, a primerand coloured top coat. Full instructions arenormally supplied with a kit, but basically, themethod of use is to first apply the pre-primerto the component concerned, and allow it todry for up to 30 minutes. Then the primer isapplied, and left to dry for about an hourbefore finally applying the special-colouredtop coat. The result is a correctly-colouredcomponent, where the paint will flex with theplastic or rubber, a property that standardpaint does not normally posses.

5 Major body damage - repair 5Where serious damage has occurred, or

large areas need renewal due to neglect, itmeans that complete new panels will needwelding-in, and this is best left toprofessionals. If the damage is due to impact,it will also be necessary to check completelythe alignment of the bodyshell, and this canonly be carried out accurately by a Peugeotdealer using special jigs. If the body is leftmisaligned, it is primarily dangerous, as thecar will not handle properly, and secondly,uneven stresses will be imposed on thesteering, suspension and possiblytransmission, causing abnormal wear, orcomplete failure, particularly to such items asthe tyres.

1 General information andprecautions

The electrical system is of 12-volt negativeearth type. Power for the lights and allelectrical accessories is supplied by alead/acid type battery, which is charged bythe alternator.

This Chapter covers repair and serviceprocedures for the various electricalcomponents not associated with the engine.Information on the battery, alternator andstarter motor can be found in Chapter 5.

It should be noted that, prior to working onany component in the electrical system, thebattery negative terminal should first bedisconnected, to prevent the possibility ofelectrical short-circuits and/or fires.Caution: If the radio/cassette player fittedhas an anti-theft security code, (thestandard unit has), refer to the precautionin the Reference section of this manualbefore disconnecting the battery.

Warning: Before carrying outany work on the electricalsystem, read the precautions in“Safety first!” at the beginningof this manual, and in Chapter 5.

2 Electrical fault finding -general information

Note: Refer to the precautions given in“Safety first!” and in Section 1 of this Chapterbefore starting work. The following tests relateto testing of the main electrical circuits, andshould not be used to test delicate electroniccircuits (such as anti-lock braking systems),particularly where an electronic controlmodule is used.

General1 A typical electrical circuit consists of anelectrical component, any switches, relays,motors, fuses, fusible links or circuit breakersrelated to that component, and the wiring andconnectors which link the component to boththe battery and the chassis. To help topinpoint a problem in an electrical circuit,wiring diagrams are included after thischapter.2 Before attempting to diagnose an electricalfault, first study the appropriate wiringdiagram, to obtain a more completeunderstanding of the components included inthe particular circuit concerned. The possiblesources of a fault can be narrowed down bynoting whether other components related tothe circuit are operating properly. If severalcomponents or circuits fail at one time, theproblem is likely to be related to a shared fuseor earth connection.3 Electrical problems usually stem fromsimple causes, such as loose or corrodedconnections, a faulty earth connection, ablown fuse, a melted fusible link, or a faultyrelay (refer to Section 3 for details of testingrelays). Visually inspect the condition of allfuses, wires and connections in a problemcircuit before testing the components. Usethe wiring diagrams to determine whichterminal connections will need to be checked,in order to pinpoint the trouble-spot.4 The basic tools required for electrical fault-finding include a circuit tester or voltmeter (a12-volt bulb with a set of test leads can alsobe used for certain tests); a self-powered testlight (sometimes known as a continuity tester);an ohmmeter (to measure resistance); abattery and set of test leads; and a jumperwire, preferably with a circuit breaker or fuseincorporated, which can be used to bypasssuspect wires or electrical components.Before attempting to locate a problem withtest instruments, use the wiring diagram todetermine where to make the connections.5 To find the source of an intermittent wiringfault (usually due to a poor or dirtyconnection, or damaged wiring insulation), a“wiggle” test can be performed on the wiring.This involves wiggling the wiring by hand, tosee if the fault occurs as the wiring is moved.It should be possible to narrow down thesource of the fault to a particular section ofwiring. This method of testing can be used in

conjunction with any of the tests described inthe following sub-Sections.6 Apart from problems due to poorconnections, two basic types of fault canoccur in an electrical circuit - open-circuit, orshort-circuit.7 Open-circuit faults are caused by a breaksomewhere in the circuit, which preventscurrent from flowing. An open-circuit fault willprevent a component from working, but willnot cause the relevant circuit fuse to blow.8 Short-circuit faults are caused by a “short”somewhere in the circuit, which allows thecurrent flowing in the circuit to “escape” alongan alternative route, usually to earth. Short-circuit faults are normally caused by abreakdown in wiring insulation, which allows afeed wire to touch either another wire, or anearthed component such as the bodyshell. Ashort-circuit fault will normally cause therelevant circuit fuse to blow.

Finding an open-circuit9 To check for an open-circuit, connect onelead of a circuit tester or voltmeter to eitherthe negative battery terminal or a known goodearth.10 Connect the other lead to a connector inthe circuit being tested, preferably nearest tothe battery or fuse.11 Switch on the circuit, bearing in mind thatsome circuits are live only when the ignitionswitch is moved to a particular position.12 If voltage is present (indicated either bythe tester bulb lighting or a voltmeter reading,as applicable), this means that the section ofthe circuit between the relevant connectorand the battery is problem-free.13 Continue to check the remainder of thecircuit in the same fashion.14 When a point is reached at which novoltage is present, the problem must liebetween that point and the previous test pointwith voltage. Most problems can be traced toa broken, corroded or loose connection.

Finding a short-circuit15 To check for a short-circuit, firstdisconnect the load(s) from the circuit (loadsare the components which draw current froma circuit, such as bulbs, motors, heatingelements, etc).16 Remove the relevant fuse from the circuit,and connect a circuit tester or voltmeter to thefuse connections.17 Switch on the circuit, bearing in mind thatsome circuits are live only when the ignitionswitch is moved to a particular position.18 If voltage is present (indicated either bythe tester bulb lighting or a voltmeter reading,as applicable), this means that there is ashort-circuit.19 If no voltage is present, but the fuse stillblows with the load(s) connected, thisindicates an internal fault in the load(s).

Finding an earth fault20 The battery negative terminal is

connected to “earth” - the metal of theengine/transmission and the car body - andmost systems are wired so that they onlyreceive a positive feed, the current returningvia the metal of the car body. This means thatthe component mounting and the body formpart of that circuit. Loose or corrodedmountings can therefore cause a range ofelectrical faults, ranging from total failure of acircuit, to a puzzling partial fault. In particular,lights may shine dimly (especially whenanother circuit sharing the same earth point isin operation), motors (eg wiper motors or theradiator cooling fan motor) may run slowly,and the operation of one circuit may have anapparently-unrelated effect on another. Notethat on many vehicles, earth straps are usedbetween certain components, such as theengine/transmission and the body, usuallywhere there is no metal-to-metal contactbetween components, due to flexible rubbermountings, etc.21 To check whether a component isproperly earthed, disconnect the battery, andconnect one lead of an ohmmeter to a knowngood earth point. Connect the other lead tothe wire or earth connection being tested. Theresistance reading should be zero; if not,check the connection as follows.22 If an earth connection is thought to befaulty, dismantle the connection, and cleanback to bare metal both the bodyshell and thewire terminal or the component earthconnection mating surface. Be careful toremove all traces of dirt and corrosion, thenuse a knife to trim away any paint, so that aclean metal-to-metal joint is made. Onreassembly, tighten the joint fastenerssecurely; if a wire terminal is being refitted,use serrated washers between the terminaland the bodyshell, to ensure a clean andsecure connection. When the connection isremade, prevent the onset of corrosion in thefuture by applying a coat of petroleum jelly orsilicone-based grease, or by spraying on (atregular intervals) a proprietary ignition sealer.

3 Fuses and relays - general information

Fuses1 Fuses are designed to break a circuit whena predetermined current is reached, in orderto protect the components and wiring whichcould be damaged by excessive current flow.Any excessive current flow will be due to afault in the circuit, usually a short-circuit (seeSection 2).2 The main fuses are located in the fusebox,below the steering column on the driver’s sideof the facia.3 For access to the fuses, on models up to1992, turn the two securing clips through aquarter-turn, then drop the fusebox paneldown from the facia. On models from 1993,

12•2 Body electrical system

prise off the cover to expose the fusebox (seeillustrations).4 Additional fuses may be located in thefusebox on the right-hand side of the enginecompartment, in front of the suspension strut,and/or at the front left-hand corner of theengine compartment (see illustration).5 A blown fuse can be recognised from itsmelted or broken wire.6 To remove a fuse, first ensure that therelevant circuit is switched off.7 Using the plastic tool provided in thefusebox, pull the fuse from its location (seeillustration).8 Spare fuses are provided in the blankterminal positions in the fusebox.9 Before renewing a blown fuse, trace andrectify the cause, and always use a fuse of thecorrect rating. Never substitute a fuse of ahigher rating, or make temporary repairs using

wire or metal foil; more serious damage, oreven fire, could result.10 Note that the fuses are colour-coded asfollows. Refer to the wiring diagrams fordetails of the fuse ratings and the circuitsprotected.

Colour RatingOrange 5ARed 10ABlue 15AYellow 20AClear or white 25AGreen 30A11 If desired, on models from 1993, thefusebox can be withdrawn from the facia asfollows.a) Pull off the fusebox cover.b) Locate the red plastic clip at the left-hand

side of the fusebox, and pull the clip torelease (see illustration).

c) Slide the fusebox to the left, and then pullthe assembly out from the facia (seeillustration).

12 The following fuses are located in theengine compartment fusebox(es).a) Cooling fan.b) ABS.c) Fuel pump (petrol engines).d) Oxygen sensor (petrol engines).e) Engine management electronic control

unit (petrol engines).

Relays13 A relay is an electrically-operated switch,which is used for the following reasons:a) A relay can switch a heavy current

remotely from the circuit in which thecurrent is flowing, allowing the use oflighter-gauge wiring and switch contacts.

b) A relay can receive more than one controlinput, unlike a mechanical switch.

c) A relay can have a timer function - forexample, the intermittent wiper relay.

14 Most of the relays are located under thefacia, behind the main fusebox, and mountedon various brackets around the steeringcolumn. The rear wiper motor relay is locatedin the tailgate, behind the tailgate trim panel.On some models, additional engine-relatedrelays are located in the relay box mounted atthe front left-hand corner of the enginecompartment, or in the left-hand corner of thescuttle (see illustrations).15 If a circuit or system controlled by a relaydevelops a fault, and the relay is suspect,operate the system. If the relay is functioning,

it should be possible to hear it “click” as it isenergised. If this is the case, the fault lies withthe components or wiring of the system. If therelay is not being energised, then either therelay is not receiving a main supply or aswitching voltage, or the relay itself is faulty.Testing is by the substitution of a known goodunit, but be careful - while some relays areidentical in appearance and in operation,others look similar but perform differentfunctions.16 To remove a relay, first ensure that therelevant circuit is switched off. The relay canthen simply be pulled out from the socket,and pushed back into position.

8 Headlight beam alignment -general information andcomponent renewal

1 Accurate adjustment of the headlight beamis only possible using optical beam-settingequipment, and this work should therefore becarried out by a Peugeot dealer or suitably-equipped workshop.2 For reference, the headlights can be finelyadjusted using a suitable-sized Allen key torotate the adjuster assemblies fitted to the

rear of each light unit. The outer adjusteralters the vertical height of the beam, whilstthe inner adjuster alters the horizontal positionof the beam (see illustrations). Prior toadjustment, ensure the vehicle is unladen, andthat the adjuster units (see below) are both setto position “0”, or “1”, as applicable.3 Each headlight unit is equipped with athree- or four-position vertical beam adjusterunit (depending on model) - this can be usedto adjust the headlight beam, to compensatefor the relevant load which the vehicle iscarrying. The adjuster units may beincorporated into the vertical beam adjusteron the back of the headlight, or on certainmodels, an adjuster switch is provided on thefacia. On models with adjusters mounted onthe headlights, access to them can be gainedwith the bonnet open. The adjusters shouldbe positioned as follows according type, andthe load being carried in the vehicle.

General1 Some models in the range are fitted with ananti-theft alarm system as standard equipment.The alarm is automatically armed and disarmedusing the remote central locking transmitter(where applicable). When the system isactivated, the alarm indicator light, located onthe facia, will flash continuously. In addition tothe alarm function, the system alsoincorporates an engine immobiliser.2 Additionally, certain petrol engine modelsare fitted with a coded engine immobiliserdevice, operated by a key pad in the centreconsole.

Anti-theft alarm system

Early models3 Note that if the doors are operated usingthe key, the alarm will not be armed ordisarmed (as applicable). Locking the doorswith the central locking remote transmitter isthe only means of activating the alarm system.4 The alarm system protects the doors andboot or tailgate, as applicable.5 Should the alarm system become faulty, thevehicle should be taken to a Peugeot dealerfor examination.

Later models6 Note that if the doors are operated usingthe key, the alarm will not be armed ordisarmed (as applicable). If for some reasonthe remote central locking transmitter failswhilst the alarm is armed, the vehicle must beunlocked using the key. In this case, the alarmsystem will activate, and must be disarmedusing the master switch (see paragraph 8).7 The alarm system has switches on thebonnet, tailgate and each of the doors. It alsohas ultrasonic sensing, which detectsmovement inside the vehicle, via sensorsmounted on either side of the vehicle interior. Ifrequired, the ultrasonic sensing facility can beswitched off, whilst retaining the switched sideof the system. To switch off the ultrasonicsensing, with the ignition switch off, depressthe alarm switch (mounted on the right of thesteering column) until the alarm indicator lighton the facia is continuously lit. Now, when thedoors are locked using the remote centrallocking transmitter, and the alarm is armed,only the switched side of the alarm system isoperational (and the alarm indicator light willrevert to its flashing mode). This facility isuseful, as it allows you to leave thewindows/sunroof open, and still arm the alarm.If the windows/sunroof are left open with theultrasonic sensing not switched off, the alarmmay be falsely triggered by a gust of wind.8 To deactivate the complete alarm system, amaster switch is provided in the enginecompartment, behind the left-hand headlight.The switch is operated by a dedicated key,and is protected by a plastic cover.9 Should the alarm system become faulty, thevehicle should be taken to a Peugeot dealerfor examination.

Coded engine immobiliser

10 This device cuts out the enginemanagement system, and prevents the enginefrom being started unless a confidential codeis keyed into the pad located in the centreconsole.11 The code can be chosen by the owner,and full details are given in the vehiclehandbook.12 When the ignition is turned on, if the greenlight on the key pad is illuminated, the systemis not working, and the engine can be startednormally. If the red light is illuminated, thesystem is working (the engine cannot bestarted, and the alarm will sound if starting isattempted).13 To de-activate the system, enter thecorrect code, which should be confirmed byfour flashes from the green light, and fourbeeps. The red light should go out, and theengine can them be started.14 If the wrong code is entered, the red lightwill stay on, and the engine cannot be started.

Disconnecting the battery

Early models15 If the battery has been disconnected,when it is reconnected, the alarm will beactivated.16 The alarm must be de-activated using theremote central locking transmitter.

Later models17 The following precautions should beobserved when disconnecting andreconnecting the battery leads on a vehicleequipped with an alarm system.18 Before disconnecting the battery, de-activate the alarm siren, using the dedicatedkey.19 When reconnecting the battery, as soonas the battery is connected, the alarm isautomatically activated. Use the remotetransmitter to turn off the alarm, then activatethe alarm siren using the dedicated key.

24 Air bag system - generalinformation, precautions andsystem de-activation

General information1 A driver’s side air bag is fitted as standardequipment on later models, and is an optionon all other models. The air bag is fitted in thesteering wheel centre pad.2 The system is armed only when the ignitionis switched on, however, a reserve powersource maintains a power supply to thesystem in the event of a break in the mainelectrical supply. The system is activated by a

“g” sensor (deceleration sensor), and iscontrolled by an electronic control unit whichis integral with the steering wheel.3 The air bag is inflated by a gas generator,which forces the bag out from its location inthe steering wheel.

Precautions

General precautions4 The following precautions must beobserved when carrying out work on a vehicleequipped with an air bag.a) Do not disconnect the battery with the

engine running.b) Before carrying out any work in the vacinity

of the air bag, removal of any of the air bagcomponents, or any welding work on thevehicle, de-activate the system asdescribed in the following sub-Section.

c) Do not attempt to test any of the air bagsystem circuits using test meters or anyother test equipment.

d) If the air bag warning light comes on, orany fault in the system is suspected,consult a Peugeot dealer without delay.Do not attempt to carry out faultdiagnosis, or any dismantling of thecomponents.

Precautions to be taken whenhandling an air baga) Transport the air bag by itself, bag

upward.b) Do not put your arms around the air bag.c) Carry the air bag close to the body, bag

outward.d) Do not drop the air bag or expose it to

impacts.e) Do not try to dismantle the air bag unit.f) Do not connect any form of electrical

equipment to any part of the air bag circuit.

Precautions to be taken when storingan air bag unita) Store the unit in a cupboard with the air

bag upward.b) Do not expose the air bag to

temperatures above 80ºC.c) Do not expose the air bag to flames.d) Do not attempt to dispose of the air bag -

consult a Peugeot dealer.e) Never refit an air bag which is known to

be faulty or damaged.

De-activation of air bag system5 The system must be de-activated beforecarrying out any work on the air bagcomponents or surrounding area.a) Switch off the ignition.b) Remove the ignition key.c) Switch off all electrical equipment.

12•20 Body electrical system

Warning: Do not forget theimmobiliser code - if the correctcode cannot be entered, theengine management electronic

control unit must be renewed.

Warning: The followingprecautions must be observedwhen working on vehiclesequipped with an air bag

system, to prevent the possibility ofpersonal injury.

d) Disconnect the battery negative lead.e) Insulate the battery negative terminal and

the end of the battery negative lead toprevent any possibility of contact.

f) Wait for at least ten minutes beforecarrying out any further work.

Activation of air bag system6 To activate the system on completion ofany work, proceed as follows.a) Ensure that there are no occupants in the

vehicle, and that there are no looseobjects around the vacinity of the steeringwheel. Close the vehicle doors andwindows.

b) Insert the ignition key, and switch on theignition.

Spare parts are available from many sources,including maker’s appointed garages, accessoryshops, and motor factors. To be sure ofobtaining the correct parts, it may sometimes benecessary to quote the vehicle identificationnumber. If possible, it can also be useful to takethe old parts along for positive identification.Items such as starter motors and alternatorsmay be available under a service exchangescheme - any parts returned should be clean.

Our advice regarding spare part sources isas follows.

Officially-appointed garagesThis is the best source of parts which are

peculiar to your car, and are not otherwisegenerally available (eg badges, interior trim,certain body panels, etc). It is also the onlyplace at which you should buy parts if thevehicle is still under warranty.

Accessory shopsThese are good places to buy materials and

components needed for the maintenance ofyour car (oil, air and fuel filters, spark plugs,light bulbs, drivebelts, oils and greases, brakepads, touch-up paint, etc). Parts like this soldby a reputable shop are of the same standardas those used by the car manufacturer.

Motor factorsGood factors will stock all the more

important components which wear outcomparatively quickly and can sometimessupply individual components needed for theoverhaul of a larger assembly. They may alsohandle work such as cylinder block reboring,crankshaft regrinding and balancing, etc.

Tyre and exhaust specialistsThese outlets may be independent or

members of a local or national chain. Theyfrequently offer competitive prices whencompared with a main dealer or local garage,but it will pay to obtain several quotes beforemaking a decision. Also ask what ‘extras’ maybe added to the quote - for instance, fitting anew valve and balancing the wheel are bothoften charged on top of the price of a newtyre.

Other sourcesBeware of parts or materials obtained from

market stalls, car boot sales or similar outlets.Such items are not invariably sub-standard,but there is little chance of compensation ifthey do prove unsatisfactory. In the case ofsafety-critical components such as brakepads there is the risk not only of financial lossbut also of an accident causing injury ordeath.

Buying Spare Parts REF•3

Vehicle identification numbersModifications are a continuing and

unpublicised process in vehicle manufacture,quite apart from major model changes. Spareparts lists are compiled upon a numericalbasis, the individual vehicle identificationnumbers being essential to correct identifi-cation of the component concerned.

When ordering spare parts, always give asmuch information as possible. Quote the carmodel, year of manufacture, body and enginenumbers, as appropriate.

The Vehicle Identification Number (VIN)plate is riveted to the top of the front crosspanel in the engine compartment. It is alsostamped into the right-hand side of the enginebulkhead.

The Engine number is situated on the frontof the cylinder block, just below the cylinderhead. On TU engines it is near the left-handend of the engine, on XU10 engines it is mid-way, and on XU5, XU7 and XU9 engines it ison the right-hand end. Note: The first part ofthe engine number gives the engine code - eg, “XU5”.

The Vehicle paint code is stamped into theleft-hand inner wing panel.

Other identification numbers or codes arestamped on major items such as the gearbox,final drive housing, distributor etc.

Whenever servicing, repair or overhaul workis carried out on the car or its components, itis necessary to observe the followingprocedures and instructions. This will assist incarrying out the operation efficiently and to aprofessional standard of workmanship.

Joint mating faces and gasketsWhen separating components at their

mating faces, never insert screwdrivers orsimilar implements into the joint between thefaces in order to prise them apart. This cancause severe damage which results in oilleaks, coolant leaks, etc upon reassembly.Separation is usually achieved by tappingalong the joint with a soft-faced hammer inorder to break the seal. However, note thatthis method may not be suitable wheredowels are used for component location.

Where a gasket is used between the matingfaces of two components, ensure that it isrenewed on reassembly, and fit it dry unlessotherwise stated in the repair procedure. Makesure that the mating faces are clean and dry,with all traces of old gasket removed. Whencleaning a joint face, use a tool which is notlikely to score or damage the face, and removeany burrs or nicks with an oilstone or fine file.

Make sure that tapped holes are cleanedwith a pipe cleaner, and keep them free ofjointing compound, if this is being used,unless specifically instructed otherwise.

Ensure that all orifices, channels or pipesare clear, and blow through them, preferablyusing compressed air.

Oil sealsOil seals can be removed by levering them

out with a wide flat-bladed screwdriver orsimilar tool. Alternatively, a number of self-tapping screws may be screwed into the seal,and these used as a purchase for pliers orsimilar in order to pull the seal free.

Whenever an oil seal is removed from itsworking location, either individually or as partof an assembly, it should be renewed.

The very fine sealing lip of the seal is easilydamaged, and will not seal if the surface itcontacts is not completely clean and free fromscratches, nicks or grooves. If the originalsealing surface of the component cannot berestored, and the manufacturer has not madeprovision for slight relocation of the sealrelative to the sealing surface, the componentshould be renewed.

Protect the lips of the seal from any surfacewhich may damage them in the course offitting. Use tape or a conical sleeve wherepossible. Lubricate the seal lips with oil beforefitting and, on dual-lipped seals, fill the spacebetween the lips with grease.

Unless otherwise stated, oil seals must befitted with their sealing lips toward thelubricant to be sealed.

Use a tubular drift or block of wood of theappropriate size to install the seal and, if theseal housing is shouldered, drive the sealdown to the shoulder. If the seal housing is

unshouldered, the seal should be fitted withits face flush with the housing top face (unlessotherwise instructed).

Screw threads and fasteningsSeized nuts, bolts and screws are quite a

common occurrence where corrosion has setin, and the use of penetrating oil or releasingfluid will often overcome this problem if theoffending item is soaked for a while beforeattempting to release it. The use of an impactdriver may also provide a means of releasingsuch stubborn fastening devices, when usedin conjunction with the appropriatescrewdriver bit or socket. If none of thesemethods works, it may be necessary to resortto the careful application of heat, or the use ofa hacksaw or nut splitter device.

Studs are usually removed by locking twonuts together on the threaded part, and thenusing a spanner on the lower nut to unscrewthe stud. Studs or bolts which have broken offbelow the surface of the component in whichthey are mounted can sometimes be removedusing a stud extractor. Always ensure that ablind tapped hole is completely free from oil,grease, water or other fluid before installingthe bolt or stud. Failure to do this could causethe housing to crack due to the hydraulicaction of the bolt or stud as it is screwed in.

When tightening a castellated nut to accepta split pin, tighten the nut to the specifiedtorque, where applicable, and then tightenfurther to the next split pin hole. Neverslacken the nut to align the split pin hole,unless stated in the repair procedure.

When checking or retightening a nut or boltto a specified torque setting, slacken the nutor bolt by a quarter of a turn, and thenretighten to the specified setting. However,this should not be attempted where angulartightening has been used.

For some screw fastenings, notablycylinder head bolts or nuts, torque wrenchsettings are no longer specified for the latterstages of tightening, “angle-tightening” beingcalled up instead. Typically, a fairly low torquewrench setting will be applied to thebolts/nuts in the correct sequence, followedby one or more stages of tightening throughspecified angles.

Locknuts, locktabs and washersAny fastening which will rotate against a

component or housing during tighteningshould always have a washer between it andthe relevant component or housing.

Spring or split washers should always berenewed when they are used to lock a criticalcomponent such as a big-end bearingretaining bolt or nut. Locktabs which arefolded over to retain a nut or bolt shouldalways be renewed.

Self-locking nuts can be re-used in non-critical areas, providing resistance can be feltwhen the locking portion passes over the boltor stud thread. However, it should be notedthat self-locking stiffnuts tend to lose their

effectiveness after long periods of use, andshould be renewed as a matter of course.

Split pins must always be replaced withnew ones of the correct size for the hole.

When thread-locking compound is foundon the threads of a fastener which is to be re-used, it should be cleaned off with a wirebrush and solvent, and fresh compoundapplied on reassembly.

Special toolsSome repair procedures in this manual

entail the use of special tools such as a press,two or three-legged pullers, springcompressors, etc. Wherever possible, suitablereadily-available alternatives to themanufacturer’s special tools are described,and are shown in use. In some instances,where no alternative is possible, it has beennecessary to resort to the use of amanufacturer’s tool, and this has been donefor reasons of safety as well as the efficientcompletion of the repair operation. Unless youare highly-skilled and have a thoroughunderstanding of the procedures described,never attempt to bypass the use of anyspecial tool when the procedure describedspecifies its use. Not only is there a very greatrisk of personal injury, but expensive damagecould be caused to the components involved.

Environmental considerationsWhen disposing of used engine oil, brake

fluid, antifreeze, etc, give due consideration toany detrimental environmental effects. Do not,for instance, pour any of the above liquidsdown drains into the general sewage system,or onto the ground to soak away. Many localcouncil refuse tips provide a facility for wasteoil disposal, as do some garages. If none ofthese facilities are available, consult your localEnvironmental Health Department, or theNational Rivers Authority, for further advice.

With the universal tightening-up oflegislation regarding the emission of environ-mentally-harmful substances from motorvehicles, most current vehicles havetamperproof devices fitted to the mainadjustment points of the fuel system. Thesedevices are primarily designed to preventunqualified persons from adjusting the fuel/airmixture, with the chance of a consequentincrease in toxic emissions. If such devicesare encountered during servicing or overhaul,they should, wherever possible, be renewedor refitted in accordance with the vehiclemanufacturer’s requirements or currentlegislation.

The jack supplied with the vehicle tool kitshould only be used for changing theroadwheels - see “Wheel changing” at thefront of this manual. When carrying out anyother kind of work, raise the vehicle using ahydraulic (or “trolley”) jack, and alwayssupplement the jack with axle standspositioned under the vehicle jacking points.

When using a hydraulic jack or axle stands,always position the jack head or axle standhead under, or adjacent to one of the relevantwheel changing jacking points (seeillustration).

To raise the front of the vehicle, position thejack with an interposed block of woodunderneath the centre of the front subframe.Alternatively, the vehicle can be jacked underthe front crossmember, but a block of wood100 x 100 x 780 mm will be required betweenthe jack and the crossmember. Do not jackthe vehicle under the sump, or any of thesteering or suspension components.

The procedure for raising the rear of thevehicle is as described for the front, but placethe jack under either the rear axle tube, forwhich a shaped block of wood approximately100 mm long will be required, or under therear panel using a 150 x 150 x 1200 mm blockof wood. Do not attempt to raise the vehiclewith the jack positioned under the sparewheel, as the vehicle floor will almost certainlybe damaged.

The jack supplied with the vehicle locatedin the jacking points in the ridges on theunderside of the sills. Ensure that the jackhead is correctly engaged before attemptingto raise the vehicle.

Never work under, around, or near a raisedvehicle, unless it is adequately supported in atleast two places.

Radio/cassette unit Anti-theft System - PrecautionThe radio/cassette unit fitted to later

models as standard equipment by Peugeot isequipped with a built-in security code, todeter thieves. If the power source to the unit iscut, the anti-theft system will activate. Even ifthe power source is immediately reconnected,the radio/cassette unit will not function untilthe correct security code has been entered.Therefore if you do not know the correctsecurity code for the unit, do not disconnect

the battery negative lead, or remove theradio/cassette unit from the vehicle.

To enter the security code, press the“on/off” button; the unit display will show“CODE”.The security code can then beentered using the buttons 1 to 6 on the unit.The unit will be activated automatically if thecorrect code is entered.

If the incorrect code is entered, the unit willlock, and the word “SECURITY” will be

displayed for 2 minutes. After 2 minutes, it willbe possible to enter a code again. If 3 wrongcodes are entered, the unit will lock for 2 hours.To clear the locking function, leave the unit andthe ignition switched on during this period.

If the security code is lost or forgotten, seekthe advice of your Peugeot dealer. Onpresentation of proof of ownership, a Peugeotdealer will be able to provide you with a newsecurity code.

IntroductionA selection of good tools is a fundamental

requirement for anyone contemplating themaintenance and repair of a motor vehicle.For the owner who does not possess any,their purchase will prove a considerableexpense, offsetting some of the savings madeby doing-it-yourself. However, provided thatthe tools purchased meet the relevant nationalsafety standards and are of good quality, theywill last for many years and prove anextremely worthwhile investment.

To help the average owner to decide whichtools are needed to carry out the various tasksdetailed in this manual, we have compiledthree lists of tools under the followingheadings: Maintenance and minor repair,Repair and overhaul, and Special. Newcomersto practical mechanics should start off withthe Maintenance and minor repair tool kit, andconfine themselves to the simpler jobs aroundthe vehicle. Then, as confidence andexperience grow, more difficult tasks can beundertaken, with extra tools being purchasedas, and when, they are needed. In this way, aMaintenance and minor repair tool kit can bebuilt up into a Repair and overhaul tool kit overa considerable period of time, without anymajor cash outlays. The experienced do-it-yourselfer will have a tool kit good enough formost repair and overhaul procedures, and willadd tools from the Special category when it isfelt that the expense is justified by the amountof use to which these tools will be put.

Maintenance and minor repair tool kit

The tools given in this list should beconsidered as a minimum requirement ifroutine maintenance, servicing and minorrepair operations are to be undertaken. Werecommend the purchase of combinationspanners (ring one end, open-ended theother); although more expensive than open-ended ones, they do give the advantages ofboth types of spanner.M Combination spanners:

Metric - 8 to 19 mm inclusiveM Adjustable spanner - 35 mm jaw (approx.)M Spark plug spanner (with rubber insert) -

petrol modelsM Spark plug gap adjustment tool - petrol

modelsM Set of feeler gaugesM Brake bleed nipple spannerM Screwdrivers:

Flat blade - 100 mm long x 6 mm diaCross blade - 100 mm long x 6 mm dia

M Combination pliersM Hacksaw (junior)M Tyre pumpM Tyre pressure gaugeM Oil canM Oil filter removal toolM Fine emery clothM Wire brush (small)M Funnel (medium size)

Repair and overhaul tool kitThese tools are virtually essential for

anyone undertaking any major repairs to amotor vehicle, and are additional to thosegiven in the Maintenance and minor repair list.Included in this list is a comprehensive set ofsockets. Although these are expensive, theywill be found invaluable as they are soversatile - particularly if various drives areincluded in the set. We recommend the half-inch square-drive type, as this can be usedwith most proprietary torque wrenches.

The tools in this list will sometimes need tobe supplemented by tools from the Special list:M Sockets (or box spanners) to cover range in

previous list (including Torx sockets)M Reversible ratchet drive (for use with

sockets)M Extension piece, 250 mm (for use with

sockets)M Universal joint (for use with sockets)M Torque wrench (for use with sockets)M Self-locking gripsM Ball pein hammerM Soft-faced mallet (plastic/aluminium or

rubber)M Screwdrivers:

Special toolsThe tools in this list are those which are not

used regularly, are expensive to buy, or whichneed to be used in accordance with theirmanufacturers’ instructions. Unless relativelydifficult mechanical jobs are undertakenfrequently, it will not be economic to buymany of these tools. Where this is the case,you could consider clubbing together withfriends (or joining a motorists’ club) to make ajoint purchase, or borrowing the tools againsta deposit from a local garage or tool hirespecialist. It is worth noting that many of thelarger DIY superstores now carry a largerange of special tools for hire at modest rates.

The following list contains only those toolsand instruments freely available to the public,and not those special tools produced by thevehicle manufacturer specifically for its dealernetwork. You will find occasional referencesto these manufacturers’ special tools in thetext of this manual. Generally, an alternativemethod of doing the job without the vehiclemanufacturers’ special tool is given. However,sometimes there is no alternative to usingthem. Where this is the case and the relevanttool cannot be bought or borrowed, you willhave to entrust the work to a dealer.M Valve spring compressorM Valve grinding toolM Piston ring compressorM Piston ring removal/installation toolM Cylinder bore honeM Balljoint separatorM Coil spring compressors (where applicable)M Two/three-legged hub and bearing pullerM Impact screwdriverM Micrometer and/or vernier calipersM Dial gaugeM Stroboscopic timing lightM Dwell angle meter/tachometerM Universal electrical multi-meterM Cylinder compression gaugeM Hand-operated vacuum pump and gaugeM Clutch plate alignment setM Brake shoe steady spring cup removal toolM Bush and bearing removal/installation setM Stud extractorsM Tap and die setM Lifting tackleM Trolley jack

Buying toolsReputable motor accessory shops and

superstores often offer excellent quality toolsat discount prices, so it pays to shop around.

Remember, you don’t have to buy the mostexpensive items on the shelf, but it is alwaysadvisable to steer clear of the very cheaptools. Beware of ‘bargains’ offered on marketstalls or at car boot sales. There are plenty ofgood tools around at reasonable prices, butalways aim to purchase items which meet therelevant national safety standards. If in doubt,ask the proprietor or manager of the shop foradvice before making a purchase.

Care and maintenance of toolsHaving purchased a reasonable tool kit, it is

necessary to keep the tools in a clean andserviceable condition. After use, always wipeoff any dirt, grease and metal particles using aclean, dry cloth, before putting the tools away.Never leave them lying around after they havebeen used. A simple tool rack on the garageor workshop wall for items such asscrewdrivers and pliers is a good idea. Storeall normal spanners and sockets in a metalbox. Any measuring instruments, gauges,meters, etc, must be carefully stored wherethey cannot be damaged or become rusty.

Take a little care when tools are used.Hammer heads inevitably become marked,and screwdrivers lose the keen edge on theirblades from time to time. A little timelyattention with emery cloth or a file will soonrestore items like this to a good finish.

Working facilitiesNot to be forgotten when discussing tools

is the workshop itself. If anything more thanroutine maintenance is to be carried out, asuitable working area becomes essential.

It is appreciated that many an owner-mechanic is forced by circumstances toremove an engine or similar item without thebenefit of a garage or workshop. Having donethis, any repairs should always be done underthe cover of a roof.

Wherever possible, any dismantling shouldbe done on a clean, flat workbench or table ata suitable working height.

Any workbench needs a vice; one with a jawopening of 100 mm is suitable for most jobs.As mentioned previously, some clean drystorage space is also required for tools, as wellas for any lubricants, cleaning fluids, touch-uppaints etc, which become necessary.

Another item which may be required, andwhich has a much more general usage, is anelectric drill with a chuck capacity of at least 8mm. This, together with a good range of twistdrills, is virtually essential for fittingaccessories.

Last, but not least, always keep a supply ofold newspapers and clean, lint-free ragsavailable, and try to keep any working area asclean as possible.

REF•8 MOT Test ChecksThis is a guide to getting your vehicle through the MOT test.

Obviously it will not be possible to examine the vehicle to the samestandard as the professional MOT tester. However, working throughthe following checks will enable you to identify any problem areasbefore submitting the vehicle for the test.

Where a testable component is in borderline condition, the testerhas discretion in deciding whether to pass or fail it. The basis of suchdiscretion is whether the tester would be happy for a close relative orfriend to use the vehicle with the component in that condition. If thevehicle presented is clean and evidently well cared for, the tester maybe more inclined to pass a borderline component than if the vehicle isscruffy and apparently neglected.

It has only been possible to summarise the test requirements here,based on the regulations in force at the time of printing. Test standardsare becoming increasingly stringent, although there are someexemptions for older vehicles. For full details obtain a copy of the Haynespublication Pass the MOT! (available from stockists of Haynes manuals).

An assistant will be needed to help carry out some of these checks.

The checks have been sub-divided into four categories, as follows:

HandbrakeM Test the operation of the handbrake.Excessive travel (too many clicks) indicatesincorrect brake or cable adjustment.M Check that the handbrake cannot bereleased by tapping the lever sideways. Checkthe security of the lever mountings.

FootbrakeM Depress the brake pedal and check that itdoes not creep down to the floor, indicating amaster cylinder fault. Release the pedal, waita few seconds, then depress it again. If thepedal travels nearly to the floor before firmresistance is felt, brake adjustment or repair isnecessary. If the pedal feels spongy, there isair in the hydraulic system which must beremoved by bleeding.

M Check that the brake pedal is secure and ingood condition. Check also for signs of fluidleaks on the pedal, floor or carpets, whichwould indicate failed seals in the brake mastercylinder.M Check the servo unit (when applicable) byoperating the brake pedal several times, thenkeeping the pedal depressed and starting theengine. As the engine starts, the pedal willmove down slightly. If not, the vacuum hose orthe servo itself may be faulty.

Steering wheel and column M Examine the steering wheel for fractures orlooseness of the hub, spokes or rim. M Move the steering wheel from side to sideand then up and down. Check that the steering wheel is not loose on the column,indicating wear or a loose retaining nut.Continue moving the steering wheel as before,but also turn it slightly from left to right. M Check that the steering wheel is not looseon the column, and that there is no abnormal

movement of the steering wheel, indicatingwear in the column support bearings orcouplings.

Windscreen and mirrors M The windscreen must be free of cracks orother significant damage within the driver’sfield of view. (Small stone chips areacceptable.) Rear view mirrors must besecure, intact, and capable of being adjusted.

REF

Seat belts and seats Note: The following checks are applicable toall seat belts, front and rear.

M Examine the webbing of all the belts(including rear belts if fitted) for cuts, seriousfraying or deterioration. Fasten and unfasteneach belt to check the buckles. If applicable,check the retracting mechanism. Check thesecurity of all seat belt mountings accessiblefrom inside the vehicle.M The front seats themselves must besecurely attached and the backrests mustlock in the upright position.

Doors M Both front doors must be able to be openedand closed from outside and inside, and mustlatch securely when closed.

Vehicle identificationM Number plates must be in good condition,secure and legible, with letters and numberscorrectly spaced – spacing at (A) should betwice that at (B).

M The VIN plate (A) and homologation plate(B) must be legible.

Electrical equipmentM Switch on the ignition and check the operation of the horn.M Check the windscreen washers and wipers,examining the wiper blades; renew damagedor perished blades. Also check the operationof the stop-lights.

M Check the operation of the sidelights andnumber plate lights. The lenses and reflectorsmust be secure, clean and undamaged. M Check the operation and alignment of theheadlights. The headlight reflectors must notbe tarnished and the lenses must beundamaged.M Switch on the ignition and check the operation of the direction indicators (includingthe instrument panel tell-tale) and the hazardwarning lights. Operation of the sidelights andstop-lights must not affect the indicators - if itdoes, the cause is usually a bad earth at therear light cluster.M Check the operation of the rear foglight(s),including the warning light on the instrumentpanel or in the switch.

FootbrakeM Examine the master cylinder, brake pipesand servo unit for leaks, loose mountings, corrosion or other damage.

M The fluid reservoir must be secure and thefluid level must be between the upper (A) andlower (B) markings.

M Inspect both front brake flexible hoses forcracks or deterioration of the rubber. Turn thesteering from lock to lock, and ensure that thehoses do not contact the wheel, tyre, or anypart of the steering or suspension mechanism.With the brake pedal firmly depressed, checkthe hoses for bulges or leaks under pressure.

Steering and suspensionM Have your assistant turn the steering wheelfrom side to side slightly, up to the point wherethe steering gear just begins to transmit thismovement to the roadwheels. Check forexcessive free play between the steeringwheel and the steering gear, indicating wear orinsecurity of the steering column joints, thecolumn-to-steering gear coupling, or thesteering gear itself.M Have your assistant turn the steering wheelmore vigorously in each direction, so that theroadwheels just begin to turn. As this is done,examine all the steering joints, linkages,fittings and attachments. Renew anycomponent that shows signs of wear or damage. On vehicles with power steering,check the security and condition of the steering pump, drivebelt and hoses.M Check that the vehicle is standing level,and at approximately the correct ride height.

Shock absorbersM Depress each corner of the vehicle in turn,then release it. The vehicle should rise andthen settle in its normal position. If the vehiclecontinues to rise and fall, the shock absorberis defective. A shock absorber which hasseized will also cause the vehicle to fail.

2Checks carried outWITH THE VEHICLE ON THEGROUND

REF•10 MOT Test Checks

Exhaust systemM Start the engine. With your assistant holding a rag over the tailpipe, check theentire system for leaks. Repair or renewleaking sections.

Jack up the front and rear of the vehicle,and securely support it on axle stands.Position the stands clear of the suspensionassemblies. Ensure that the wheels areclear of the ground and that the steeringcan be turned from lock to lock.

Steering mechanism M Have your assistant turn the steering fromlock to lock. Check that the steering turnssmoothly, and that no part of the steeringmechanism, including a wheel or tyre, foulsany brake hose or pipe or any part of the bodystructure.M Examine the steering rack rubber gaitersfor damage or insecurity of the retaining clips.If power steering is fitted, check for signs ofdamage or leakage of the fluid hoses, pipes orconnections. Also check for excessivestiffness or binding of the steering, a missingsplit pin or locking device, or severe corrosionof the body structure within 30 cm of anysteering component attachment point.

Front and rear suspension andwheel bearings M Starting at the front right-hand side, graspthe roadwheel at the 3 o’clock and 9 o’clockpositions and shake it vigorously. Check forfree play or insecurity at the wheel bearings,suspension balljoints, or suspension mount-ings, pivots and attachments.M Now grasp the wheel at the 12 o’clock and6 o’clock positions and repeat the previousinspection. Spin the wheel, and check forroughness or tightness of the front wheelbearing.

M If excess free play is suspected at acomponent pivot point, this can be confirmedby using a large screwdriver or similar tool andlevering between the mounting and thecomponent attachment. This will confirmwhether the wear is in the pivot bush, itsretaining bolt, or in the mounting itself (the boltholes can often become elongated).

M Carry out all the above checks at the otherfront wheel, and then at both rear wheels.

Springs and shock absorbers M Examine the suspension struts (whenapplicable) for serious fluid leakage, corrosion,or damage to the casing. Also check thesecurity of the mounting points.M If coil springs are fitted, check that thespring ends locate in their seats, and that thespring is not corroded, cracked or broken.M If leaf springs are fitted, check that allleaves are intact, that the axle is securelyattached to each spring, and that there is nodeterioration of the spring eye mountings,bushes, and shackles.

M The same general checks apply to vehiclesfitted with other suspension types, such astorsion bars, hydraulic displacer units, etc.Ensure that all mountings and attachments aresecure, that there are no signs of excessivewear, corrosion or damage, and (on hydraulictypes) that there are no fluid leaks or damagedpipes.M Inspect the shock absorbers for signs ofserious fluid leakage. Check for wear of themounting bushes or attachments, or damageto the body of the unit.

Driveshafts(fwd vehicles only)M Rotate each front wheel in turn and inspectthe constant velocity joint gaiters for splits ordamage. Also check that each driveshaft isstraight and undamaged.

Braking system M If possible without dismantling, checkbrake pad wear and disc condition. Ensurethat the friction lining material has not wornexcessively, (A) and that the discs are notfractured, pitted, scored or badly worn (B).

M Examine all the rigid brake pipesunderneath the vehicle, and the flexiblehose(s) at the rear. Look for corrosion, chafingor insecurity of the pipes, and for signs ofbulging under pressure, chafing, splits ordeterioration of the flexible hoses.M Look for signs of fluid leaks at the brakecalipers or on the brake backplates. Repair orrenew leaking components.M Slowly spin each wheel, while yourassistant depresses and releases thefootbrake. Ensure that each brake is operatingand does not bind when the pedal is released.

REF

M Examine the handbrake mechanism,checking for frayed or broken cables,excessive corrosion, or wear or insecurity ofthe linkage. Check that the mechanism workson each relevant wheel, and releases fully,without binding.M It is not possible to test brake efficiencywithout special equipment, but a road testcan be carried out later to check that thevehicle pulls up in a straight line.

Fuel and exhaust systemsM Inspect the fuel tank (including the fillercap), fuel pipes, hoses and unions. Allcomponents must be secure and free fromleaks.M Examine the exhaust system over its entirelength, checking for any damaged, broken ormissing mountings, security of the retainingclamps and rust or corrosion.

Wheels and tyres M Examine the sidewalls and tread area ofeach tyre in turn. Check for cuts, tears, lumps,bulges, separation of the tread, and exposureof the ply or cord due to wear or damage.Check that the tyre bead is correctly seatedon the wheel rim, that the valve is sound and

properly seated, and that the wheel is notdistorted or damaged. M Check that the tyres are of the correct sizefor the vehicle, that they are of the same sizeand type on each axle, and that the pressuresare correct.M Check the tyre tread depth. The legalminimum at the time of writing is 1.6 mm overat least three-quarters of the tread width.Abnormal tread wear may indicate incorrectfront wheel alignment.

Body corrosionM Check the condition of the entire vehiclestructure for signs of corrosion in load-bearing areas. (These include chassis boxsections, side sills, cross-members, pillars,and all suspension, steering, braking systemand seat belt mountings and anchorages.)Any corrosion which has seriously reducedthe thickness of a load-bearing area is likely tocause the vehicle to fail. In this caseprofessional repairs are likely to be needed.M Damage or corrosion which causes sharpor otherwise dangerous edges to be exposedwill also cause the vehicle to fail.

Petrol modelsM Have the engine at normal operatingtemperature, and make sure that it is in goodtune (ignition system in good order, air filterelement clean, etc).M Before any measurements are carried out,raise the engine speed to around 2500 rpm,and hold it at this speed for 20 seconds. Allowthe engine speed to return to idle, and watch

for smoke emissions from the exhausttailpipe. If the idle speed is obviously muchtoo high, or if dense blue or clearly-visibleblack smoke comes from the tailpipe for morethan 5 seconds, the vehicle will fail. As a ruleof thumb, blue smoke signifies oil being burnt(engine wear) while black smoke signifiesunburnt fuel (dirty air cleaner element, or othercarburettor or fuel system fault).M An exhaust gas analyser capable ofmeasuring carbon monoxide (CO) andhydrocarbons (HC) is now needed. If such aninstrument cannot be hired or borrowed, alocal garage may agree to perform the checkfor a small fee.

CO emissions (mixture)M At the time of writing, the maximum COlevel at idle is 3.5% for vehicles first used afterAugust 1986 and 4.5% for older vehicles.From January 1996 a much tighter limit(around 0.5%) applies to catalyst-equippedvehicles first used from August 1992. If theCO level cannot be reduced far enough topass the test (and the fuel and ignitionsystems are otherwise in good condition) thenthe carburettor is badly worn, or there is someproblem in the fuel injection system orcatalytic converter (as applicable).

HC emissionsM With the CO emissions within limits, HCemissions must be no more than 1200 ppm(parts per million). If the vehicle fails this testat idle, it can be re-tested at around 2000rpm; if the HC level is then 1200 ppm or less,this counts as a pass.M Excessive HC emissions can be caused byoil being burnt, but they are more likely to bedue to unburnt fuel.

Diesel modelsM The only emission test applicable to Dieselengines is the measuring of exhaust smokedensity. The test involves accelerating theengine several times to its maximumunloaded speed.

Note: It is of the utmost importance that theengine timing belt is in good condition beforethe test is carried out.

M Excessive smoke can be caused by a dirtyair cleaner element. Otherwise, professionaladvice may be needed to find the cause.

REF•12 Fault Finding

IntroductionThe vehicle owner who does his or her own maintenance according

to the recommended service schedules should not have to use thissection of the manual very often. Modern component reliability is suchthat, provided those items subject to wear or deterioration areinspected or renewed at the specified intervals, sudden failure iscomparatively rare. Faults do not usually just happen as a result ofsudden failure, but develop over a period of time. Major mechanicalfailures in particular are usually preceded by characteristic symptomsover hundreds or even thousands of miles. Those components whichdo occasionally fail without warning are often small and easily carriedin the vehicle.

With any fault-finding, the first step is to decide where to begininvestigations. Sometimes this is obvious, but on other occasions, alittle detective work will be necessary. The owner who makes half adozen haphazard adjustments or replacements may be successful incuring a fault (or its symptoms), but will be none the wiser if the faultrecurs, and ultimately may have spent more time and money than wasnecessary. A calm and logical approach will be found to be moresatisfactory in the long run. Always take into account any warningsigns or abnormalities that may have been noticed in the periodpreceding the fault - power loss, high or low gauge readings, unusualsmells, etc - and remember that failure of components such as fuses orspark plugs may only be pointers to some underlying fault.

The pages which follow provide an easy-reference guide to themore common problems which may occur during the operation of thevehicle. These problems and their possible causes are groupedunder headings denoting various components or systems, such asEngine, Cooling system, etc. The Chapter and/or Section which dealswith the problem is also shown in brackets. Whatever the fault,certain basic principles apply. These are as follows:

Verify the fault. This is simply a matter of being sure that you knowwhat the symptoms are before starting work. This is particularlyimportant if you are investigating a fault for someone else, who maynot have described it very accurately.

Don’t overlook the obvious. For example, if the vehicle won’t start, isthere fuel in the tank? (Don’t take anyone else’s word on this particularpoint, and don’t trust the fuel gauge either!) If an electrical fault is

indicated, look for loose or broken wires before digging out the test gear.Cure the disease, not the symptom. Substituting a flat battery with

a fully-charged one will get you off the hard shoulder, but if theunderlying cause is not attended to, the new battery will go the sameway. Similarly, changing oil-fouled spark plugs for a new set will getyou moving again, but remember that the reason for the fouling (if itwasn’t simply an incorrect grade of plug) will have to be establishedand corrected.

Don’t take anything for granted. Particularly, don’t forget that a“new” component may itself be defective (especially if it’s beenrattling around in the boot for months), and don’t leave componentsout of a fault diagnosis sequence just because they are new orrecently-fitted. When you do finally diagnose a difficult fault, you’llprobably realise that all the evidence was there from the start.

6 Automatic transmissionNote: Due to the complexity of the automatic transmission, it isdifficult for the home mechanic to properly diagnose and service thisunit. For problems other than the following, the vehicle should betaken to a dealer service department or automatic transmissionspecialist.

Fluid leakagemm Automatic transmission fluid is usually deep red in colour. Fluid

leaks should not be confused with engine oil, which can easilybe blown onto the transmission by air flow.

mm To determine the source of a leak, first remove all built-up dirtand grime from the transmission housing and surrounding areas,using a degreasing agent or by steam-cleaning. Drive the vehicleat low speed, so that air flow will not blow the leak far from itssource. Raise and support the vehicle, and determine where theleak is coming from. The following are common areas of leakage.

a) Fluid pan (Chapter 1 and 7B).b) Dipstick tube (Chapter 1 and 7B).c) Transmission-to-fluid cooler fluid pipes/unions (Chapter 7B).

Transmission fluid brown, or has burned smellmm Transmission fluid level low, or fluid in need of renewal

(Chapter 1).

General gear selection problemsmm Chapter 7B deals with checking and adjusting the selector cable

on automatic transmissions. The following are commonproblems which may be caused by a poorly-adjusted cable:

a) Engine starting in gears other than Park or Neutral.b) Indicator on gear selector lever pointing to a gear other than the

one actually being used.c) Vehicle moves when in Park or Neutral.d) Poor gear shift quality, or erratic gear changes.

mm Refer to Chapter 7B for the selector cable adjustment procedure.

Transmission will not downshift (kickdown) with accelerator pedal fully depressedmm Low transmission fluid level (Chapter 1).mm Incorrect selector cable adjustment (Chapter 7B).

Engine will not start in any gear, or starts in gears other than Park or Neutralmm Incorrect starter/inhibitor switch adjustment - where applicable

(Chapter 7B).mm Incorrect selector cable adjustment (Chapter 7B).

Transmission slips, shifts roughly, is noisy, or has no drive in forward or reverse gearsmm There are many probable causes for the above problems, but the

home mechanic should be concerned with only one possibility -fluid level. Before taking the vehicle to a dealer or transmissionspecialist, check the fluid level and condition of the fluid asdescribed in Chapter 1. Correct the fluid level as necessary, orchange the fluid and filter if needed. If the problem persists,professional help will be necessary.

Clicking or knocking noise on turns (at slow speed on full-lock)mm Lack of constant velocity joint lubricant, possibly due to

damaged gaiter (Chapter 8).mm Worn outer constant velocity joint (Chapter 8).

Vibration when accelerating or deceleratingmm Worn inner constant velocity joint (Chapter 8).mm Bent or distorted driveshaft (Chapter 8).
