Engine Oil Pressure Lamp TurnsOnWhat to do if the engine oil pressure lampturns on.

It is important to maintain oil pressurewithin acceptable limits. If oil pressuredrops below the minimum psi a redwarning lamp on the oil pressure gaugeand the Stop Engine Lamp will come ON.

CAUTION

Continuing to operate your vehicle withinsufficient oil pressure will cause seri-

ous engine damage. Failure to complymay result in equipment or propertydamage.

• If the oil pressure fails to rise within10 seconds after the engine starts,stop the engine and determine thecause.

• See Engine Oil Specification for thecorrect oil pressure ranges for yourvehicle's engine.

• If the oil pressure suddenly drops,or the audible alarm and engine oilpressure warning light come onwhile driving, do the following:

1. Slow down carefully.2. Move a safe distance off the road

and stop.3. Place the transmission in neutral

(N) and set the parking brake. (SeeParking Brake Valve and Operatingthe Transmission in your vehicleOperator's Manual, fortransmission shifting and parkingbrake information.)

4. Turn OFF the engine.5. Turn ON the emergency flasher

and use other warning devices toalert other motorists.

6. Wait a 15–20 minutes to allow oil todrain into the engine oil pan, andthen check the oil level. SeeEngine Oil Level.

7. Add oil if necessary. If the problempersists, contact an authorizedPACCAR engine dealer as soon aspossible.

Check Engine Lamp Turns OnWhat to do if the check engine lamp turnson.

Or

Check Engine Lamp - Turns on when aproblem exists, but the vehicle can still besafely driven. Vehicle should be serviced tocorrect the problem but the situation shouldnot be considered an emergency.The lamp will also illuminate when a DPFregeneration or addition of diesel exhaustfluid (DEF) is required. Another function of

the check engine lamp is to warn theoperator of an impending idle shutdown.When the idle shutdown timer is 30seconds from expiring, the ECM beginsflashing the check engine warning lamponce per second. When the timer expires,the ECM will turn off the warning lamp andshut down the engine.

Engine is OverheatingThe cooling system may overheat if thecoolant level is below normal or if there issudden loss of coolant. Follow these stepsif the engine is overheating.

CAUTION

The cooling system may overheat ifthe engine coolant is at the minimumlevel. A sudden loss of coolant,caused by a split hose or broken hoseclamp could also lead to an overheatcondition. Always inspect to ensurehoses and clamps are not cracked,worn, or loose. Failure to comply may

result in equipment or property dam-age.

NOTE

The system may also temporarily over-heat during severe operating condi-tions such as:• Climbing a hill on a hot day.• Stopping after high-speed/ high-

load driving.• Debris blocking air flow through

the cooling module (radiator).

If the engine coolant temperature warninglamp comes on and the audible alarmsounds showing an overheat condition, orif you have any other reason to suspect theengine may be overheating, DO NOTTURN OFF THE ENGINE unless a lowwater warning device indicates a loss ofcoolant. Follow these steps:Follow these steps if the engine coolanttemperature is rising, or the temperature isalready above normal, and there are noother warning alarms displayed in theinstrument cluster.

1. Reduce engine speed, or stop.When stopped, place the

transmission in neutral (N) and setthe parking brake. Keep the enginerunning. See the vehicle operator'smanual for instructions ontransmission shifting and parkingbrake information.

WARNING

To reduce the chance of personal in-jury, vehicle damage and/or deathfrom overheated engines, which canresult in a fire, never leave the engineidling without an alert driver present. Ifthe engine should overheat, as indicat-ed by the engine coolant temperaturelight, immediate action is required tocorrect the condition. Continued unat-tended operation of the engine, evenfor a short time, may result in seriousengine damage or a fire. Failure tocomply may result in death, personalinjury, equipment or property damage.

WARNING

Removing the fill cap on a hot enginecan cause scalding coolant to sprayout and burn you badly. If the enginehas been in operation within the previ-ous 30 minutes, be very careful in re-moving the fill cap. Protect face,hands, and arms against escaping flu-id and steam by covering the cap witha large, thick rag. DO NOT try to re-move it until the surge tank cools downor if you see any steam or coolant es-caping. In any situation, remove thecap very slowly and carefully. Be readyto back off if any steam or coolant be-gins to escape.

NOTE

Keep the engine running at idle speedunless a warning icon turns on and re-quires an engine to be shut off.

CAUTION

Prolonged periods of idling after theengine has reached operating temper-

atures can decrease engine tempera-ture and could cause engine damagefrom inadequate lubrication. The nor-mal torsional vibrations generated canalso cause transmission wear. An idleshutdown feature, available on PAC-CAR engines, can be programmed toshut the engine down after a period oflow idle operation with no driver activi-ty. A flashing warning lamp will informthe driver of an impending shutdown.Failure to comply may result in equip-ment or property damage.

CAUTION

If the truck is equipped with powertake off (PTO) equipment, the engineshutdown system can be deactivatedwhen the PTO is operational; however,engine idle periods should not exceedfive minutes whenever possible. Fail-ure to comply may result in equipmentor property damage.

2. Check to ensure the Oil PressureGauge reads normal.

3. Make sure the engine fan is turningby switching the Engine Fan Switchfrom AUTO to MAN (Manual).

4. Increase the engine speed to aboutone-half of full operating speed, or1,100 to 1,200 rpm, maximum for 2or 3 minutes.

5. Return the engine speed to normalidle. Monitor the enginetemperature. After the temperaturereturns to normal, allow the engineto idle 3 to 5 minutes beforeshutting it off. This allows theengine to cool gradually anduniformly.

6. If overheating came from severeoperating conditions, thetemperature should have cooled bythis time. If it has not, stop theengine and let it cool beforechecking to see if the coolant islow.

7. Be sure the vehicle is parked onlevel ground or the readings maybe incorrect. Check the coolantlevel at the cooling module surgetank.

Check the coolant level after each tripwhen the engine has cooled. The coolantlevel should be visible within the surge tank—add coolant if necessary.

In somecases, the Malfunction Indicator Lamp(MIL) will activate in conjunction with theHigh Exhaust System Temperature(HEST), Diesel Particulate Filter (DPF) andDiesel Exhaust Fluid (DEF) warning lamps.

NOTE

The malfunction indicator lamp (MIL)will illuminate if the on-board diagnos-tics (OBD) system detects a possibleemissions system failure. The vehicleshould be brought in for service at thenext opportunity to ensure the condi-tion is corrected.

Diesel Particulate Filter (DPF)Warning LampThis warning symbol will appear when theDPF needs to be regenerated and thenalso during the regeneration cycle. Thisicon may also appear if the system isattempting to automatically regeneratewhile the vehicle is in Power Take Offoperation mode.

Engine aftertreatment system includes adiesel particulate filter and DPF warninglamp.

High Exhaust System Temperature(HEST) Warning LampEngine aftertreatment system includes ahigh exhaust system temperature (HEST)warning lamp.

Keep vehicle a safe distance fromcombustible items.

WARNING

Temperature of the tail pipe, exhaustpipe, the diesel particular filter (DPF) /selective catalytic reduction (SCR) de-vice and surrounding components in-cluding enclosures and steps, will beelevated during and shortly after a re-generation event or normal vehicle op-eration when engine is under high orheavy loading.

If the High Exhaust System Temperature(HEST) warning lamp is on:

• Do not park in an area ofcombustible vapors or materials.You must keep combustibles atleast 1.5 m (5 ft) away from theexhaust (outlet) stream (as it exitsthe tail pipe) while the HEST lampis illuminated. Always park yourvehicle outside. Failure to do socould ignite an explosion or harmbystanders which could result inserious injury.

• Do not park in an area wherepeople are close by. You must keep

Engine Braking SystemInformation on using the engine brakingsystem.

An engine compression brake is standardon the MX-13 engines. Optionally, thisengine may be equipped with an exahustbrake. When activated, these devices

create a braking effect on the drive wheels.Because it can help keep your vehicle’sbrakes from overheating, it can save wearand tear on the service brakes. However,the engine compression or exhaust brakeis not an emergency brake or the primaryvehicle brake.

WARNING

Do not operate the engine compres-sion brake when driving/operating yourvehicle bobtail or with a loaded or un-loaded trailer on road surfaces withpoor traction (wet, icy, or snow cov-ered roads) or in heavy traffic. Theremay not be enough weight on the rearaxle to provide traction. Brakingcaused by the normal operation of theengine compression brake couldcause you to lose control of the vehi-cle, resulting in an injury accident.Make sure the engine brake is switch-ed "OFF" when bobtailing or with anunloaded trailer. Failure to comply mayresult in death, personal injury, equip-ment or property damage.


16 Y53-1181-1K1 (08/2018)

1

WARNING

The service brakes must be used in anemergency. The engine compressionbrake alone might not stop the vehiclefast enough to prevent an accident.The engine compression brake is NOTintended as the primary brake for thevehicle, nor is it an emergency brake.The engine compression brake onlyhelps the service brakes by using en-gine back pressure to slow the drive-train. Use the service brakes for quickstops. You could be seriously injured ifyou relied only on the engine compres-sion brake to stop the vehicle in anemergency. Failure to comply may re-sult in death, personal injury, equip-ment or property damage.

CAUTION

DO NOT operate the engine brake un-til the engine oil temperature is above86°F (30°C). Operation below 86°F(30°C) could cause severe damage tothe engine. Idle the engine four mi-nutes at approximately 1000 rpm to

warm the engine before activating theengine brakes.

NOTE

If your vehicle is equipped with anti-lock brakes (ABS), operation of thecompression brake (if turned ON) maybe interrupted if the ABS system de-tects wheel-slip due to operation onslippery surfaces.

Ideally (on normal road surfaces), youshould slow your vehicle with thecompression brake (where permitted bylaw) and use the service brakes only forstopping completely. Operating this waywill greatly prolong the life of the servicebrakes.

Compression BrakeProper use of engine compression brakes.

With the compression brake switch ON, thebrake automatically creates its brakingeffect when you remove your foot from theaccelerator pedal.The brake switch is located on theaccessory dash panel. It controls whether

the brake is ON (ready to slow the vehicledown) or OFF (no braking action).

1. Do not use the engine compressionbrake to slow the vehicle downwhen you are bobtailing or pullingan empty trailer.

2. Make sure the brake is OFF beforestarting the engine.

3. After the engine is started, warmedup and you are ready to get underway, turn the engine compressionbrake switch ON for added brakingeffect.

NOTE

If your vehicle is equipped with the Ea-ton Vorad® system, operation of thecompression brake may be automati-cally activated.

Compression Brake ControlsUsing the compression brake controls.

There are two switches on the dash panelthat control the engine compression brake.A master switch turns the system ON orOFF. A second switch, located next to themaster switch, controls the braking effect.This switch allows you to choose


Y53-1181-1K1 (08/2018) 17

progressively stronger braking to slow thevehicle down.Engine compression brake controlsinclude:

• ON/OFF switch• Three-position selector switch• Clutch switch• Throttle sensor• Service brake pressure switch• Eaton Vorad® Anti-Lock Braking

SystemEngaging conditions for the enginecompression brake:

• Engine speed must be above 1,000RPM.

• Coolant temperature must beabove 59°F (15°C).

Deactivation conditions for the enginecompression brake:

• Accelerator pedal is depressed.• Clutch pedal is depressed.• Engine speed falls below 800

RPM.• ABS control is active.• ECM recognizes a system

problem.

CAUTION

Operating the engine with a compres-sion brake that will not automaticallydeactivate (i.e. when the dash switchis OFF, clutch pedal is depressed orthrottle is applied) will cause severe in-ternal engine damage. Do not operatethe engine if the compression brakewill not deactivate. Failure to complymay result in equipment or propertydamage.

Engine Compression Brake LevelSwitch OperationHow to operate the compression brake.

There are two switches that control yourvehicle’s engine compression brake. Oneswitch turns the system ON/OFF and thesecond switch controls the braking level.These switches are located on the dashswitch panel.For the three-position engine compressionbrake level switch, there will be 100percent engine braking when the switch isin the up (HIGH) position. In the middle(MEDIUM) position, there will be 66percent engine braking. In the down (LOW)

position there will be 33 percent enginebraking.With the compression brake switch ON, thecompression brake will be engaged whenthe service brake is applied. If the cruisecontrol is operated in conjunction with thecompression brake, the compression brakewill engage to maintain the cruise setspeed.Compression on\off

DrivingIntroduction and important informationabout operating your vehicle safely.

Correct care of your engine will result inlonger life, better performance, and moreeconomical operation.Follow the daily maintenance checks listedin Engine Maintenance on page 29.Check the engine oil pressure and enginecoolant gauges, warning lamps, and othergauges daily to make sure they areoperational. Normally each gauge willmake a full sweep when ignition key iscycled ON to indicate that the gauge isoperating correctly.

WARNING

Combustible vapors near the air intakesystem could be ingested into the en-gine, causing the engine to suddenlyaccelerate and overspeed. This condi-tion could result in operator losing con-trol of the vehicle if an unexpected in-crease in engine RPM occurs. Com-bustible vapors could also cause a fire.Do not operate your vehicle in an areawhere combustible chemicals or va-pors may be present. Failure to com-ply may result in death, personal in-jury, equipment or property damage.

Cold Weather StartingSteps for starting the engine in coldtemperatures.

Follow this engine starting procedure whenthe outside temperature is below 50° F(10° C).

CAUTION

To reduce the possibility of damage tothe lubricating oil pan, due to the ma-terials used in the manufacture of thelubricating oil pan, under no circum-stances should an external heatsource be applied directly or indirectlyto the lubricating oil pan.

1. Follow the Normal StartingProcedure on page 20.

Refer to the vehicle operator's manualinstructions for any additional cold weatherstarting procedures.

2. If starting a cold engine, slowlyincrease the engine speed. Thisprovides adequate lubrication tothe bearings and gives ample time

to allow the oil pressure tostabilize.

CAUTION

The use of starting aids, such as ether,may result in damage to the engineand aftertreatment system.

If an engine must idle for an extendedperiod of time, it should be done at a fastidle (1,000 RPM maximum) at coolanttemperatures below 150°F (70°C).

3. For coolant temperatures below150°F (70°C), use a low gear anddrive at moderate engine speeduntil the engine coolant hasreached operating temperature. Donot let the engine idle longer thannecessary.

CAUTION

Do not operate the engine at low idlefor long periods of time when the cool-ant temperature is below the normaloperating range. This could result inthe following:

• Fuel dilution of the lubricatingoil.

• Carbon buildup in the com-bustion chamber.

• Sticking of the valves in thecylinder head.

• Reduced performance.• Damage to aftertreatment

components.

Starting Procedure After ExtendedShutdown or Oil ChangeGuideline on starting the engine afterprolonged shutdown or oil change.

After extended shutdown or an oil changefollow the Normal Starting Procedure onpage 20.

Operating the EngineAfter the engine starts:

Monitor the oil pressure and coolanttemperature gauges frequently. Refer to Engine Oil Specifications on page 40 and Engine Coolant Specifications on page 45for recommended operating pressures andtemperatures. Shut off the engine if anypressure or temperature does NOT meetthe specifications.

Engine Operating RangeInformation on operating the engine atproper RPM.

CAUTION

Operating the engine at full throttle be-low peak torque will shorten engine lifeto overhaul, can cause serious enginedamage, and is considered engineabuse. DO NOT operate the engine atfull throttle operation below peak tor-que rpm for more than 30 seconds.Failure to comply may result in equip-ment or property damage.

PACCAR engines are designed to operateat full throttle under momentary conditionsdown to peak torque engine speed. This isconsistent with recommended operatingpractices.

CAUTION

Operating the engine beyond the max-imum engine speed can cause severeengine damage. Use proper operatingtechniques for the vehicle to preventengine overspeed. See Engine Speci-

fications for maximum engine speed.Failure to comply may result in equip-ment or property damage.

NOTE

For applications with high idle-time, tohelp reduce soot loading in the after-treatment system, avoid long periodsof idling. If idling is required, increaseidle-speed using the cruise controlfunction.

Engine ShutdownBefore stopping the engine follow theseprecautions.

NOTE

DO NOT shut off the engine immedi-ately. A hot engine stores a greatamount of heat and it does not cooldown immediately after it is shut off.Always cool the engine down beforeshutting it off. You will greatly increaseits service life.

Idle the engine at 1,000 RPM for fourminutes. Then low idle for 30 secondsbefore shutdown. This will allow circulatingcoolant and lubricating oil to carry heataway from the cylinder head, valves,pistons, cylinder liners, turbocharger, andbearings. This way you can prevent enginedamage that may result from unevencooling.

Electromagnetic InterferenceInformation on electromagneticinterference (EMI).

If not installed correctly, some vehicleaccessories (CB radios, mobiletransmitters, etc.) can generate and useradio frequency energy that may causeelectromagnetic interference (EMI)between the accessory and theelectronically controlled fuel system. Underthese conditions, PACCAR is not liable forany performance problems with either thefuel system or the accessory. EMI is notconsidered by PACCAR to be an enginefailure and therefore is not warrantable.

System EMI SusceptibilityPACCAR products are designed andtested for minimum sensitivity to incomingelectromagnetic energy. The fuel system


22 Y53-1181-1K1 (08/2018)

1

EMI susceptibility has been designed witha high tolerance against EMI and in mostnormal circumstances, if not all,electromagnetic energy-emitting devicesthat meet the Federal CommunicationsCommission legal requirements shouldcause no interference.

System EMI Radiation LevelsElectronic components are required topass various PACCAR and industry EMIspecifications. Our testing has shown thatwhen the engine is properly installed andmaintained, it will not interfere with properlyinstalled onboard communicationequipment.If any interference condition is noticed,follow these suggestions to reduce theamount of EMI:

1. Locate the accessory receivingantenna further away.

2. Check with the accessory supplierrepresentative in your area to:

• Accurately calibrate theaccessory for proper frequency,power output, and sensitivity.

• Determine the optimumantenna location by obtainingantenna reflective energy datameasurements.

• Ensure that the optimumantenna type and mountingarrangement is being used.

• Ensure the accessoryequipment is properlyconstructed for maximumfiltering to reject incomingelectromagnetic noise.

Operating on Level and DryPavementTips for driving on level and dry roads.

WARNING

Do not use the engine brake when op-erating on road surfaces with poortraction (such as wet, icy, or snow cov-ered roads or gravel). Retarders cancause the wheels to skid on a slipperysurface. You could lose control of thevehicle and/or jackknife if the wheelsbegin to skid, resulting in an accident.Failure to comply may result in death,personal injury, equipment or propertydamage.

WARNING

Do not operate the engine compres-sion brake when driving/operating yourvehicle bobtail or with a loaded or un-loaded trailer on road surfaces withpoor traction (wet, icy, or snow cov-ered roads) or in heavy traffic. Theremay not be enough weight on the rearaxle to provide traction. Brakingcaused by the normal operation of theengine compression brake couldcause you to lose control of the vehi-cle, resulting in an injury accident.Make sure the engine brake is switch-ed "OFF" when bobtailing or with anunloaded trailer. Failure to comply mayresult in death, personal injury, equip-ment or property damage.

Operating on Grades and DryPavementTips for driving on grades and dry roads.

WARNING

The engine brake is not intended asthe primary brake for the vehicle, noris it an emergency brake. The servicebrakes must be used in an emergency.Relying solely on the engine brake tostop the vehicle in an emergencycould cause an accident and lead topersonal injury. The engine brake onlyhelps the service brakes by using

pressure to slow the drive train. Youmust use the service brakes for quickor emergency stops. Failure to complymay result in death, personal injury,equipment or property damage.

WARNING

DO NOT use an exhaust brake whendriving bobtail or with an unloadedtrailer. There may not be enoughweight on the rear axle to provide trac-tion. This could cause a loss of controland jackknife resulting in an injury ac-cident. Make sure the exhaust brake isswitched “OFF” when bobtailing orwith an unloaded trailer. Failure tocomply may result in death, personalinjury, equipment or property damage.

CAUTION

Never exceed governed engine speedbecause engine damage can occur.Operating engine beyond the gov-erned speed causes additional strainon valve train and internal engine com-ponents. Operate the engine withingoverned engine speed.

NOTE

Once you have determined what thesafe speed is for your vehicle, operatethe engine brakes with the transmis-sion in the lowest gear that will notcause the engine speed to exceed therated engine speed. The optimumbraking power of the engine brakes isreached at rated engine speed. Cor-rect gear selection, therefore, is criti-cal.

The selector switch can be used to varybraking power as road conditions change.Vehicle service brakes must be used whenadditional braking power is required.Slow Down Around Curves

Tips for Operation on Slick Roads

WARNING

To reduce the possibility of personalinjury or property damage, always al-low for extra distance between yourvehicle and other objects when usingthe service brakes or engine brakes onslick roads.

The operation of any vehicle is difficult topredict on slick roads. The first 10 to 15minutes of rainfall are the most dangerous,as road dirt and oil mixed with rain create avery slippery surface.

WARNING

Do not use any of the vehicle’s retard-ers in any situation that requires an im-mediate stop and/or in situations ofpoor traction (such as wet, icy or snowcovered roads). Trying to use the re-tarder instead of the service brakesmay cause a loss of vehicle control,which may result in an accident involv-ing death or personal injury.

When driving on slick roads, start with the“ON/OFF” switch in the “OFF” position andthe two-position selector switch in the“LOW” position. If your tractor is equippedwith a twin-screw rear axle, position thepower divider switch in the “unlocked”position. Remove your foot from theaccelerator pedal to make sure the vehiclewill maintain traction with the retardingpower of the engine alone. If the vehicledrive wheels begin to skid or if there is afishtailing motion, DO NOT activate theengine brakes. If traction is maintained


26 Y53-1181-1K1 (08/2018)

using the retarding power of the enginealone and more braking power is required,switch the two-position selector switch tothe “LOW” position and activate the enginebrakes by switching the “ON/OFF” switchto the “ON” position. If the vehicle’s drivewheels begin to skid or there is a fishtailingmotion, switch the “ON/OFF” switch to the“OFF” position. If traction is maintainedwhen the engine brakes are activated andmore braking power is required, move thetwo-position selector switch to the “HI”position. Again, if the vehicle has losttraction or if there is a fishtailing motion,switch the “ON/OFF” switch to the “OFF”position. DO NOT attempt to use theengine brakes in the “HI” position.

MaintenanceRequirements

Engine MaintenanceIntroduction and important maintenancerequirements.

PACCAR recommends that the engine bemaintained according to the maintenanceschedule in this section.If the engine is operating in ambienttemperatures below 0°F (-18°C) or above100°F (38°C), perform maintenance atshorter intervals. Shorter maintenanceintervals are also required if the engine isoperated in a dusty environment or iffrequent stops are made.Some of these maintenance proceduresrequire special tools or must be completedby qualified personnel. Contact your localPACCAR authorized repair location fordetailed information.If your engine is equipped with acomponent or accessory not manufacturedby PACCAR Inc, refer to the componentmanufacturer's maintenancerecommendations.

WARNING

Never idle your vehicle for prolongedperiods of time if you sense that ex-haust fumes are entering the cab. In-vestigate the cause of the fumes andcorrect it as soon as possible. If thevehicle must be driven under theseconditions, drive only with the windowsopen. Failure to repair the source ofthe exhaust fumes may result in death,personal injury, equipment or propertydamage.

WARNING

Exhaust fumes from the engine con-tain carbon monoxide, a colorless andodorless gas. Do not breathe the en-gine exhaust gas. A poorly maintained,damaged or corroded exhaust systemcan allow carbon monoxide to enterthe cab. Entry of carbon monoxide intothe cab is also possible from other ve-hicles nearby. Failure to properly main-tain your vehicle could cause carbonmonoxide to enter the cab, resulting indeath or personal injury.

Cleaning the EngineEngine cleaning precautions.

When cleaning the engine, follow theinstructions from the vehicle manufactureroperator's manual and observe allenvironmental protection regulations.

CAUTION

Do not direct water onto electricalcomponents, plug connectors, seals orflexible hoses on the engine. Watermay enter the part causing electricaldamage or contaminating the engineoil. To prevent damage to engine com-ponents, keep the water moving at alltimes while cleaning the engine. Fail-ure to comply may result in equipmentdamage.

Coolant LevelDaily and refueling maintenance check forengine coolant level.

Replacement or top up coolant shouldhave the same antifreeze concentrationand corrosion inhibitor content as theoriginal coolant in the cooling system. Ifoperating in sub-freezing conditions, a60/40 mix of antifreeze and distilled watermay be substituted.Always dilute antifreeze to the correctconcentration based on freeze protectionbefore adding it to the cooling system.Adding or using 100% antifreeze in acooling system may result in cooling

system plugging and overheatingproblems.This procedure should be followed as partof daily and refueling maintenance checks.Perform the following steps to check thecoolant level:

1. Check that vehicle is a on a levelsurface.

2. Ensure engine has not been run forseveral hours.

CAUTION

Due to thermal expansion the coolantlevel CANNOT be checked if the cool-ant is above ambient temperature orthe engine has not completely cooled.The coolant level indicated on awarmed system will be inaccurate andcan lead to low coolant conditions dur-ing cold-starts.

3. Check coolant level. It should bevisible through the clear plasticsurge tank.

4. Add coolant as necessary untilproper level is reached.

Engine Lubricating OilRecommendations andSpecificationsPACCAR engine oil type, viscosity, andadditives.

A major factor in maintaining engineperformance and durability is the properuse of quality engine lubricating oils usedin conjunction with the appropriate oil drainand filter change intervals. Attempting toextend the oil and filter change intervalbeyond the manufacturersrecommendations may decrease enginelife due to factors such as corrosion,deposits, and wear.See Engine Lubrication and Filter Intervalsto determine which oil drain interval to usefor an application.

NOTE

It is the operator’s responsibility to fol-low these recommendations to ensurethat the engine warranty is not affect-ed.

PACCAR recommends the use of high-quality SAE 10W-30 API CK-4/CJ-4 heavy-duty engine oil.The primary PACCAR recommendation isfor the use of 10W-30 multigradelubricating oil for normal operation atambient temperatures above 5°F (-15°C).For ambient temperatures below 5°F(-15°C) SAE 5W-30 may be used, providedit meets API CK-4/CJ-4 oil specificationsand biodiesel or biodiesel blended fuel isnot used as fuel for the engine. Using amultigrade oil helps improve enginecranking in low-temperature conditions,reduces deposit formation, increasesengine durability and increases fueleconomy.Engine Oil Viscosity Chart

The cooling system in your vehicle wasfactory filled with extended life coolant thatmeets or exceeds all ASTM D6210 andCaterpillar EC-1 requirements. PACCARrecommends only using a 50/50 mixture ofdistilled water and ELC when coolingsystem service is required. A 50/50 mixtureof ELC and distilled water will providefreeze protection down to –34°F (–36.7°C),which is adequate for most locations inNorth America. For extremely coldoperating conditions, a 60/40 mixture(coolant/water ratio) can be used toprovide freeze protection down to -62°F(-52.2°C).Unless otherwise optioned, factory fillcoolant is an ethylene glycol, nitritedorganic acid technology (NOAT) extendedlife coolant (ELC) formulation at a 50:50coolant-to-distilled water mixture. Thefactory fill exceeds ASTM D6210 andCaterpillar EC-1 requirements. Maintainingcoolant chemistry and freeze protection iscritical to engine and cooling systemcomponent health and longevity.

WARNING

Coolant is toxic. DO NOT get the fluidin eyes. If contact occurs, flood eyes

with large amounts of water for 15 mi-nutes. Avoid prolonged or repeatedcontact with skin. In case of contact,immediately wash skin with soap andwater. DO NOT take internally. If swal-lowed, seek immediate medical atten-tion. DO NOT induce vomiting. Failureto comply may result in death, person-al injury, equipment or property dam-age.

CAUTION

The engine cooling system has veryspecific maintenance and inspectionrequirements. Failure to follow require-ments can damage the engine. Enginedamage can include but is not limitedto freezing, boiling, corrosion, pittedcylinder liners. This information isfound in the engine manufacturersowner’s manual. It is the owner’s re-sponsibility to follow all requirementslisted in the engine manufacturersowner’s manual.

NOTE

Coolant is harmful to the environment.Unused coolant must be stored as atoxic hazardous material in leakproofcontainers. Used coolant must beprocessed as industrial chemicalwaste. Please follow HAZMAT guide-lines with both used and unused cool-ants.

CAUTION

Use of non-genuine coolant filters cancause severe engine damage.

ConcentrationCheck the level of freeze/boiloverprotection, which is determined by theglycol concentration. Use a glycolrefractometer to determine glycol level.Add coolant to obtain the coolant/waterratio required to provide the protection youneed. A 50/50 mix of coolant and water isadequate for most applications. Forextremely cold operating conditions, theratio can be adjusted to a higherconcentration of coolant.


Y53-1181-1K1 (08/2018) 43

ConditionPerform a visual inspection of the coolant.It should have no cloudiness or floatingdebris. Determine the chemical inhibitorconcentration level by using an extendedlife coolant specific test kit or test strips.Inhibitor concentration level determinescorrosion protection. If you are concernedabout possible coolant quality,contamination, or mechanical problems,submit a coolant sample for analysis.Improper maintenance may cause coolantdegradation and could result in damage tothe cooling system and enginecomponents. Consult your dealer orthe coolant manufacturer’s representativefor recommended extended life coolant testkits, test strips, and laboratory sampleprocedures.

Coolant ExtenderAdd extended life coolant extender, ifnecessary, according to the corrosioninhibitor concentration required. DO NOTadd coolant extender to nitrite-free coolant.

Checking Coolant LevelCheck the coolant level daily. See CoolantLevel on page 30. When adding coolant,avoid mixing different brands and

formulations. If the coolant is mixed withmore than 25% of a different formulation,engine corrosion damage could occur. Ifmixing exceeds 25% of total systemvolume, it is recommended to flush andrefill the system completely with one typeof coolant.

Coolant FilterYour engine is equipped with a coolantfilter designed to capture and removeharmful deposits from the cooling systemto help prolong system life. It is a "blankfilter" and does not contain chemicals ortime-release additives. Replace it only witha blank filter at the interval specified in thePreventative Maintenance Schedule.Never use filters that contain supplementalcoolant additives (SCAs) in an ELC-filledsystem.

Fuel RecommendationsPrecautions and recomendations forselecting and using the right diesel fuel.

WARNING

The use of diesel fuel that has beenmixed with other fuels may cause anexplosion. DO NOT mix gasoline, alco-hol, or gasohol with diesel fuel. Makesure you know your fuel source anduse the recommended diesel fuel asindicated in this section of the manual.Failure to comply may result in death,

personal injury, equipment or propertydamage.

CAUTION

Dirt or water in the fuel system cancause severe damage to both the fuelpump and the fuel injectors. Due to theprecise tolerances of diesel injectionsystems, it is extremely important thatthe fuel be kept clean and free of dirtor water. Know your fuel source andmake sure all steps are taken for dis-pensing or using clean fuel in your ve-hicle. Failure to comply may result inequipment or property damage.

ENGINE MAINTENANCE - Fuel Recommendations

46 Y53-1181-1K1 (08/2018)

CAUTION

Unapproved fuel can reduce economyor possibly damage fuel system com-ponents. Unapproved fuels typically donot have enough lubricity elements inthe fuel to properly lubricate the fuelinjection system. Be sure you followthe fuel recommendations as indicatedin this section of the manual. Failure tocomply may result in equipment orproperty damage.

CAUTION

Using diesel fuels blended with lubri-cants may cause damage to your ex-haust aftertreatment system. Serviceintervals for aftertreatment systemswill be reduced. DO NOT use dieselfuel blended with lubricating oil in en-gines equipped with an aftertreatmentsystem. Failure to comply may resultin equipment or property damage.

CAUTION

DO NOT use high-sulfur diesel fuel asit will damage the exhaust aftertreat-ment system. Also, the engine will notmeet emission regulations. Use onlyultra-low-sulfur diesel (ULSD) fuel.Failure to comply may result in equip-ment or property damage.

CAUTION

If ultra-low-sulfur diesel (ULSD) fuel isnot used, the engine may not meetemission regulations, and damagemay occur to the exhaust aftertreat-ment system. The use of high-sulfurdiesel fuel will damage the exhaust af-tertreatment system and impact theengine emission. ULSD fuel is re-quired for correct operation of the af-tertreatment. The engine has been op-timized for use with an aftertreatmentsystem together with ULSD fuel tomeet the 2013 U.S. EnvironmentalProtection Agency regulations. Failure

to comply may result in equipment orproperty damage.

NOTE

PACCAR recommends that the cetanenumber of diesel fuel be a minimum of45 for engines that are expected to op-erate at temperatures below 32ºF(0ºC) and a minimum of 42 for enginesthat are operated at temperaturesabove 32ºF (0ºC).

Using diesel fuel with a lower-than-recommended cetane number can causehard starting instability, and excessivewhite smoke. To maintain satisfactoryoperation at low ambient temperatures, it isimportant to specify diesel fuel of thecorrect cetane number.PACCAR requires all permissible fuels tohave adequate fuel lubricity. Lubricity canbe determined by ASTM, specificationD6079, ISO 12156, High FrequencyReciprocating Rig (HFRR) in which the fuelmust have a wear scar diameter of 0.02 in.(0.5 mm) or less.The use of Ultra-low-sulfer-diesel (ULSD)fuel is required for this engine in order to

Warranty and the Use ofBiodiesel FuelBiodiesel information and warrantyprecautions.

PACCAR Inc. approves the use ofbiodiesel fuel blends from 6 to 20 percentby volume in diesel fuel providing that thefollowing conditions are met:

• The biodiesel used in the blendmeets ASTM Standard D6751 orEN 14214 specifications.

• The biodiesel used in the blend issourced from a BQ-9000Accredited Producer.

• The finished blend meets the fuelproperties of the ASTM StandardD975 (up to B5 blend) or D7467(B6 to B20 blend).

• The engine oil and oil filter arechanged per the modifiedschedule. See the EnginePreventative MaintenanceSchedule.

• The fuel filter is changed every25,000 miles/40,000 km.

The use of approved biodiesel fuel doesnot affect the PACCAR engine warranty.Failures caused by the use of non-approved biodiesel fuels or other fueladditives that are of unacceptable qualityor do not meet specified industry standardsare not considered as defects of parts orworkmanship by PACCAR and thereforewill not be covered by the PACCAR enginewarranty.PACCAR recommends that customersintending to use biodiesel blends becomefamiliar with the additional handlingconsiderations of these fuels such asageing, metal compatibility and tendency toabsorb water. Please reference the fuelsupplier’s technical information or industryguidelines such as the American TruckingAssociation Truck Maintenance Councildocument RP 357.In particular, operators should be awarethat biodiesel blends are more prone tocold flow (gelling) and filter plugging issuescompared to conventional diesel fuel. If

vehicles are expected to be operated intemperatures below freezing, care shouldbe taken to ensure that both the biodieselfuel used and the appropriate vehicle fuelsystem accessory heaters are utilized.Operators should also be aware thatbiodiesel energy content (by volume) islower than diesel which can reduce fueleconomy by up to two percent.

Recommendations toAvoid Fuel GellingInformation to prevent fuel gelling.

• Use appropriate fuel grade/blendfor conditions.

• Specify vehicle with proper coldweather equipment (12v electricpre-heater, fuel blending valve, fuelcoolant heater, 12v line heatersand tank heaters).

PACCAR does not recommend the use offuel additives, however, should a customerdecide there is a need for temporary use ofa winter fuel additive, PACCAR offers thefollowing guidance:

• Use an industry known, high qualityproduct (EPA approved).

Cooling SystemImportant information on replacing coolantfilters.

Your engine may be equipped with acoolant filter designed to capture andremove harmful deposits from the coolingsystem to help prolong system life. Refer tothe Preventative Maintenance Schedule forthe recommended coolant filter changeservice interval.

WARNING

Do not remove the surge tank fill capon a hot engine. It can cause scaldingcoolant to spray out and you could beburned. If the engine has been operat-ed within the last 30 minutes, be verycareful in removing the radiator cap.Protect face, hands, and arms againstescaping fluid and steam by coveringthe cap with a large, thick rag. Failureto comply may result in death, person-al injury, equipment or property dam-age

WARNING

Handle coolant and antifreeze careful-ly. Ethylene glycol antifreeze is poison-ous. Store in original fluid containeronly, and always keep out of the reachof children. Never remove the filler cap(vertically mounted) on the surge tankwhile the engine is still hot. Wait untilthe coolant temperature is below120°F (50°C). Scalding steam and flu-id under pressure may escape andcause serious personal injuries. The

pressure cap (horizontally mounted)on the surge tank should never beopened. Failure to comply may resultin death, personal injury, equipment orproperty damage.

Coolant/Antifreeze ConditionMaintenance checks for ensuring propercoolant\anti-freeze condition.


NOTE

Test the engine coolant at least twiceper year to determine if the coolantmust be replaced. If it is determinedthat the coolant should be replaced,make sure to flush the coolant system.Contact a PACCAR authorized repairlocation for flushing the coolant sys-tem.

1. Check the following anti-freezeconditions:

• Freeze point• Coolant level


Y53-1181-1K1 (08/2018) 63

2

• pH level• Nitrite level• Carboxylate level

Checking Coolant ConditionRecommended coolant checks.

To ensure the Extended Life Coolant (ELC)in your vehicle always provides maximumprotection, perform the following tests:

1. Check the coolant color at everymaintenance interval. Itshould have no cloudiness, floatingdebris, or oils.

2. Test the freeze point at least twicea year. A refractometer or teststrips can be used to measure theprotection level.

3. Determine the pH and chemicalinhibitor concentration level byusing an ELC-specific test kit ortest strips.

4. Keep the cooling system full bytopping-up using ELC pre-diluted toa 50/50 blend, unless a differentratio of water/antifreeze has beensubstituted (depending onoperating conditions).

NOTE

Inhibitor concentration level deter-mines corrosion protection. If you areconcerned about possible coolantquality, contamination, or mechanicalproblems, submit a coolant sample toyour dealer for analysis. Impropermaintenance may cause coolant deg-radation and could result in damage tothe cooling system and engine compo-nents. Consult your dealer or the cool-ant manufacturer's representative forrecommended extended life coolanttest kits, test strips, and laboratorysample procedures.
