Cooling System

Preventive Maintenance

While the engine is running at a high temperature room, frequently check the temperature indicator.

Level Check (Daily)

1. Remove radiator cap.

2. If necessary, complete the level with potable water up to the lower part of the filling neck.

Caution: Never check the engine coolant level immediately after stopping the engine. This could cause aserious burning.

3. If level is frequently low, operate the engine and check it for eventual leakages.

4. If it is necessary to fill up the radiator while engine is still hot, keep it at a middle acceleration regime.

Caution: Do not drain the engine coolant from a hot engine with its coolant system pressurized.

NP 085.70.67 25


4. With the engine turned off, refill the cooling system by the coolant

expansion tank nozzle until the fluid starts to leak through the draining

hole on top of thermostatic valves cover.

Cooling System Filling

(MS 4.1 TA Radiator Capacity: 17 liters)

1. Check the cooling system level capacity (engine/radiator/expansion tank,

if applicable) on Instruction and/or User's Manual supplied by the final

product manufacturer.

Caution: Never check the engine coolant level immediately afterstopping the engine. This could cause a serious burning.

2. Remove radiator cap.

3. Remove coolant bleeding plug, located at cylinder head front end.

NP 085.70.6726


Caution: Only fill the expansion tank with coolant with theengine cold. The coolant should contain: 60% cleanwater, 40% anti-freeze additive.

At low temperature areas, composition of coolantshould be: 50% clean water, 50% antifreeze additive.

Carefully read the instructions on the product packingbefore using it.

NP 085.70.67 27


Coolant Circuit Drainage

Caution: Do not drain the engine coolant from a hot engine with its coolant system pressurized.

deformation.

NP 085.70.6728


Engine Coolant Refilling

After draining the cooling circuit, follow the instructions from section "Refilling"for refilling the system with engine coolant.

Coolant nozzle cap

The cap controls the cooling system's internal pressure by means of its reliefand depressor valve. If it is necessary to remove the cap while the engine ishot, turn it until its first step for internal pressure relieving before its removal.In case it is defective, never try to fix it, but replace it for a new one instead.

Caution: Never operate an engine with the coolant capremoved. Never improvise another type of cap.

NP 085.70.67 29


Fuel System

Preventive Maintenance

Fuel is an important factor to assure the good engine operation without failures for a long time. Fuel must be clean, exemptof water and impurities.

If the fuel to be used in your engine was stored, see FUEL STORAGE.

During the engine operation, watch the fuel indicator.

Fill the fuel tank before it reaches its minimum fuel level to avoid suctioning the dirt deposited on its bottom and damagingthe filter.

Refueling

1. Clean filling nozzle cap whenever is necessary.

2. At end of each operation day, fill the fuel tank up to avoid air humidity condensation inside it.

Caution: After refueling, keep the fuel tank cap well closed. Never improvise. If the cap has any problem,replace it for an original part.

Bleed air from the system whenever the engine stops due to a lack of fuel.

Do not smoke nor approach any type of exposed flame or sparks during refueling, because dieselfuel is highly inflammable.

NP 085.70.6730


3. In periods of intense cold weather (0°C or less), add 20% of aviation

kerosene to diesel fuel. This procedure will prevent a fuel piping obstruction

by paraffin contained in diesel fuel.

During refueling, put kerosene first into the tank and then add the fuel.

Note: Use only aviation kerosene at places where temperatureis below zero degree centigrade (0°C).

Fuel Filter and Pre-Filter

The filters retain the fuel impurities, in a manner that the system receives aclean fuel, this way avoiding damages to engine fuel injection pump andinjection nozzles.

Note: Use only genuine filter elements and replace them withinthe recommended periods

NP 085.70.67 31


Filter and Pre-Filter Drainage

Daily, to avoid a premature filter obstruction and to assure the fuel injectionpump and injection nozzles durability, it is necessary to drain the filter beforethe first start.

1. Loosen drainage plug on filter and pre-filter head.

2. Manually operate the bleeding pump to drain water, sediment and

impurities from filter.

3. Retighten drain plug as soon as clean fuel flows.

NP 085.70.6732


Filters replacement

Before disassembling it, clean the external surfaces of filter and pre-filter.

1. Drain the filter and pre-filter.

Lubricating Oil and Filter Change

If the engine operates in places with a great dust concentration or other harmful condition for its good operation, it will benecessary to reduce the change interval of both filter and lubricating oil.

Caution: After the first revision (2500 km) or 50 h, the lubricating oil, together with the filter, mustobligatorily be replaced at most each 7.500 km (200 hours) or 6 months, prevailing what occursfirst

During the drainage, lubricating oil will be hot and could cause burns.

Belt

If the engine stops due to overheating, or if the battery is frequentlydischarged, check the belt for loosening or breakage.

Belt Tension Check

The tension is correct if the belt is displaced by approximately 10 mm whenyour thumb presses it at a middle point between water pump and alternatorpulleys.

Otherwise, adjust it by loosening the adjustment arm and distribution housingcover bolts.

Conservation of inactive engines

In order to avoid corrosion in an engine that will be inactive for a long period, it is necessary to take the following measures:

1. Correctly clean the outer parts of the engine.

2. Run engine up to the normal operating temperature. Next, stop it and drain the oil from oil sump.

3. Remove the oil sump, clean the oil suction pipe and replace the lubricant oil filter cartridge.

4. Clean breath pipe.

5. After reinstalling the filter, fill the oil sump up to the maximum level, marked on lubricant oil dipstick with SHELL ENSIS

ENGINE MOTOR oil.

6. Drain the fuel tank and fill it with SHELL CALIBRATION FLUID B oil.

7. Run engine until it reaches its normal operating temperature.

8. Drain engine coolant from engine and radiator.

9. Remove air filter or any extension of the intake piping and protect the air intake opening with adhesive tape.

10. Remove exhaust pipe and protect exhaust and intake manifolds openings.

11. Disconnect the battery and remove it for storage.

Caution: Handle battery carefully, it contains acid. Protect your eyes and hands.

12. Remove fan belt.

13. Complete battery electrolyte level with distillated water. Clean battery terminals, lubricate them with grease and

charge the battery. Do not use quick charging. Store it in a fresh, dry and dust free place. Complete its charge once

a month.

14. Clean starter motor and alternator terminals and apply a thin layer of grease. If the vehicle is exposed to the weather,

protect the alternator, starter motor, and instruments panel.

15. Clean starter motor and alternator terminals and apply a thin coat of grease on them. If the vehicle is to be stored

outside, then alternator, starter motor and instruments panel must be protected from bad weather

Engine preparation to return to operation

Before starting an engine which has been inactive for a long time, take the following cautions:

. Perfectly clean all the outer parts.

2. Close all engine block and radiator drain plugs and fill cooling system with clean water. Check it for leakages.

3. Turn the fan by hand to assure the water pump seals are free.

4. Install fan belt and adjust its tension.

5. Remove valves cover, lubricate rocker arms with engine oil and install it again.

6. Clean and install air filter and intake duct, remove the adhesive tape from intake and exhaust manifolds.

7. Install exhaust pipe.

8. Pressurize the engine oil galleries with oil (50/60 lbf/in.²) and turn crankshaft by hand in order to detach it from

bearing shells. Depressurize the system and remove pressurization tank.

9. Connect the battery(ies):

Caution: Do not invert cables position in relation to battery poles during terminals connection.First connect positive terminal.

10. Remove the excess of grease from alternator and starter motor terminals. Check if all connections are OK.

11. Drain oil from oil sump and fill it up to correct level with the recommended oil.

12. Remove adhesive tape from fuel tank nozzle or fuel tank pipe breath.

13. Drain fuel from fuel tank and fill it with a new one.

14. Replace fuel filter element.

15. Bleed air from fuel system.

Note: By following these instructions, theengine will not be damaged byreturning to work.

MWM INTERNATIONAL Motores Ltda.is not responsible for damaging to theengine caused by incorrectprocedures.

Fuel storage

Clean fuel, free of water, impurities and foreign materials are important factors to assure a good engine operation, for a longtime and without failures.

Water, dirt and sulfur contained in fuel are responsible for dregs formation in oil sump, deposits in compression ringsgrooves, cylinders walls, injection nozzles and exhaust valves, besides impairing the good operation of fuel injection pump.The usage of recommended lubricants contributes efficiently to neutralize, to avoid or to reduce the harmful effects ofthese products during engine operation.

The function of the engine fuel filtering system is to avoid that dirt and impurities from fuel could damage fuel injectionsystem high precision parts.

Careless refueling overloads the engine fuel filtering system, compromising its main purpose.

NP 085.70.6746


Influence of altitude in engine performance

When naturally aspirated engines are used at high altitude locations, the atmospheric air rarefaction will affect theirperformance. The quantity of air decreases, while fuel delivery remains the same, making the air-fuel mixture richer andlowering its power due to the incomplete combustion.

In this case, it is necessary to decrease the amount of fuel delivered to combustion chamber.

Note: Any adjustment or fuel injection pump setting must be done at the pump manufacturer Distributor..

Any other information can be requested to Service and Marketing Department of MWM INTERNATIONAL Motores Ltda.São Bernardo do Campo, SP, Brazil, or any representative of our Dealers and / or Authorized Service Network.
