Maintenance Recommendations

Alternator and Fan Belts - Inspect/Adjust

Check the alternator and the battery charger for

correct operation. If the batteries are correctly

charged, the ammeter reading should be very near

zero. All batteries should be kept charged. The

batteries should be kept warm because temperature

affects the cranking power. If the battery is too cold,

the battery will not crank the engine. When the engine

is not run for long periods of time or if the engine is

run for short periods, the batteries may not fully

charge. A battery with a low charge will freeze more

easily than a battery with a full charge.

Install the gauge (1) at the center of the belt between

the alternator and the crankshaft pulley and check the

belt tension. The correct tension for a new belt is

400 N (90 lb) to 489 N (110 lb). The correct tension

for a used belt that has been in operation for 30

minutes or more at the rated speed is 267 N  (60 lb) to

356 N (80 lb).

If twin belts are installed, check and adjust the

tension on both belts.

Inspection

To maximize the engine performance, inspect the

belts for wear and for cracking. Replace belts that are

worn or damaged.

For applications that require multiple drive belts,

replace the belts in matched sets. Replacing only one

belt of a matched set will cause the new belt to carry

more load because the older belt is stretched. The

additional load on the new belt could cause the new

belt to break.

If the belts are too loose, vibration causes

unnecessary wear on the belts and pulleys. Loose

belts may slip enough to cause overheating.

Illustration 25

To check accurately the belt tension, a suitable gauge

should be used.

Battery Electrolyte Level -

Check

Batteries give  off combustible  gases  which can

explode.  A   spark  can  cause   the  combustible

gases to ignite. This can result in severe personal

injury or death.

When the engine is not run for long periods of time or

when the engine is run for short periods, the batteries

may not fully recharge. Ensure a full charge in order

to help prevent the battery from freezing. If batteries

are correctly charged, the ammeter reading should be

very near zero, when the engine is in operation.

Ensure proper ventilation for batteries that are in

an enclosure. Follow the proper procedures in or-

der to  help prevent electrical arcs  and/or sparks

near batteries. Do  not smoke when  batteries are

serviced.

All lead-acid batteries contain sulfuric acid which

can  burn the  skin and  clothing.  Always wear  a

face shield and protective clothing when working

on or near batteries.

The battery cables or the batteries  should not be

removed with the battery cover in place. The bat-

tery cover should be  removed before any servic-

ing is attempted.

Removing the battery cables or the batteries with

the cover in place may cause a battery explosion

resulting in personal injury.

1. Remove the filler caps. Maintain the electrolyte

level to the “FULL”  mark on the battery.

If the addition of water is necessary, use distilled

water. If distilled water is not available use clean

water that is low in minerals. Do not use artificially

softened water.

1. Switch the engine to the OFF position. Remove all

electrical loads.

2. Turn off any battery chargers. Disconnect any

battery chargers.

2. Check the condition of the electrolyte with a

suitable battery tester.

3. The NEGATIVE “-”  cable connects the NEGATIVE

“-”  battery terminal to the NEGATIVE  “-”  terminal

on the starting motor. Disconnect the cable from

the NEGATIVE “-”  battery terminal.

3. Install the caps.

4. Keep the batteries clean.

Clean the battery case with one of the following

cleaning solutions:

4. The POSITIVE “+”  cable connects the POSITIVE

“+”  battery terminal to the POSITIVE  “+”  terminal

on the starting motor. Disconnect the cable from

the POSITIVE “+”  battery terminal.

•   Use a solution of 0.1 kg (0.2 lb) baking soda

and 1 L (1 qt) of clean water.

Coolant Temperature

Regulator - Replace

Check the coolant level when the engine is stopped

and cool.

Replace the water temperature regulator before the

water temperature regulator fails. This is a

recommended preventive maintenance practice.

Replacing the water temperature regulator reduces

the chances for unscheduled downtime.

A water temperature regulator that fails in a partially

opened position can cause overheating or

overcooling of the engine.

A water temperature regulator that fails in the closed

position can cause excessive overheating. Excessive

overheating could result in cracking of the cylinder

head or piston seizure problems.

Illustration 33

g00285520

A water temperature regulator that fails in the open

position will cause the engine operating temperature

to be too low during partial load operation. Low

engine operating temperatures during partial loads

could cause an excessive carbon buildup inside the

cylinders. This excessive carbon buildup could result

in an accelerated wear of the piston rings and wear of

the cylinder liner.

Cooling system filler cap

Pressurized System: Hot coolant can  cause seri-

ous burns. To open the cooling system filler cap,

stop the engine and wait until the cooling system

components are cool. Loosen the cooling system

pressure.

NOTICE

Failure to  replace your  water temperature  regulator

on a  regularly scheduled  basis could  cause severe

engine damage.

1. Remove the cooling system filler cap slowly in

order to relieve pressure.

Perkins   engines incorporate a shunt design  cooling

system and require operating the engine with a water

temperature regulator installed.

2. Maintain the coolant level at the maximum mark

that is correct for your application. If the engine is

equipped with a sight glass, maintain the coolant

level to the correct level in the sight glass.

If the  water temperature  regulator is installed  incor-

rectly,  the  engine  may  overheat,  causing  cylinder

head damage.  Ensure that  the new water  tempera-

ture regulator is  installed in the original position. En-

sure that the water temperature regulator vent hole is

open.

3. Clean the cooling system filler cap and inspect the

gasket. If the gasket is damaged, discard the old

filler cap and install a new filler cap. If the gasket is

not damaged, use a suitable pressurizing pump in

order to pressure test the filler cap. The correct

pressure is stamped on the face of the filler cap. If

the filler cap does not retain the correct pressure,

install a new filler cap.

Do not use liquid gasket material on the gasket or cyl-

inder head surface.

Refer to the Disassembly and Assembly Manual,

“Water Temperature Regulator - Remove and Install”

for the replacement procedure of the water

temperature regulator, or consult your Perkins

dealer or your Perkins  distributor.

4. Inspect the cooling system for leaks.

Note: If only the water temperature regulators are

replaced, drain the coolant from the cooling system to

a level that is below the water temperature regulator

housing.

When any  servicing or  repair of  the engine  cooling

system  is  performed  the  procedure  must  be  per-

formed with the engine on level ground. This will allow

you to accurately check the coolant level. This will al-

so help in avoiding  the risk of introducing an air lock

system filler cap.

Cooling system  coolant additive  contains alkali.

To  help  prevent  personal  injury,  avoid  contact

with the skin  and the eyes. Do  not drink cooling

system coolant additive.

Note: Always discard drained fluids according to local

regulations.

2. If necessary, drain some coolant from the cooling

system into a suitable container in order to allow

space for the extra SCA.

Test for SCA Concentration

Use a Coolant Conditioner Test Kit in order to check

the concentration of the SCA.

Add the SCA, If Necessary

NOTICE

Do not exceed the  recommended amount of supple-

mental coolant additive concentration. Excessive sup-

plemental  coolant  additive  concentration  can  form

deposits on  the  higher temperature surfaces  of the

cooling system,  reducing the  engine's heat  transfer

characteristics.  Reduced heat  transfer  could cause

cracking of the cylinder head and other high tempera-

ture  components.  Excessive  supplemental  coolant

additive  concentration  could also  result  in  radiator

tube blockage, overheating, and/or accelerated water

pump seal wear. Never use  both liquid supplemental

coolant additive and the spin-on element (if equipped)

Make sure that the electrical system is OFF. Lock

out the starting controls and tag the controls “DO

NOT OPERATE”  .

NOTICE

Accumulated grease  and oil  on  an engine  is a  fire

hazard. Keep the  engine clean. Remove  debris and

fluid spills  whenever  a significant  quantity accumu-

lates on the engine.

NOTICE

Never service the air cleaner element with the engine

running since this will allow dirt to enter the engine.

Servicing the Air Cleaner Elements

Periodic cleaning of the engine is recommended.

Steam cleaning the engine will remove accumulated

oil and grease. A clean engine provides the following

benefits:

Note: The air filter system may not have been

provided by Perkins . The procedure that follows is

for a typical air filter system. Refer to the OEM

information for the correct procedure.

•   Easy detection of fluid leaks

•   Maximum heat transfer characteristics

•   Ease of maintenance

If the air cleaner element becomes plugged, the air

can split the material of the air cleaner element.

Unfiltered air will drastically accelerate internal engine

wear. Refer to the OEM information for the correct air

cleaner elements for your application.

Note: Caution must be used in order to prevent

electrical components from being damaged by

excessive water when the engine is cleaned.

Pressure washers and steam cleaners should not be

directed at any electrical connectors or the junction of

cables into the rear of the connectors. Avoid electrical

components such as the alternator, the starter, and

the ECM. Protect the fuel injection pump from fluids in

order to wash the engine.

•   Check the precleaner (if equipped) and the dust

bowl daily for accumulation of dirt and debris.

Remove any dirt and debris, as needed.

•   Operating in dirty conditions may require more

frequent service of the air cleaner element.

•   The air cleaner element should be replaced at

least one time per year. This replacement should

be performed regardless of the number of

cleanings.

Replace the dirty air cleaner elements with clean air

cleaner elements. Before installation, the air cleaner

elements should be thoroughly checked for tears and/

or holes in the filter material. Inspect the gasket or the

seal of the air cleaner element for damage. Maintain a

supply of suitable air cleaner elements for

replacement purposes.

NOTICE

Keep all parts clean from contaminants.

NOTICE

Perform this maintenance with the engine stopped.

Contaminants may  cause rapid wear and  shortened

component life.

Do not drain the oil when the engine is cold. As the oil

cools, suspended waste particles settle on the bottom

of the oil pan. The waste particles are not removed

with the draining cold oil. Drain the crankcase with the

engine stopped. Drain the crankcase with the oil

warm. This draining method allows the waste

particles that are suspended in the oil to be drained

correctly.

Note: Oil gauge (A) or oil gauge (B) may be installed

in the engine.

1. Maintain the oil level between “ADD” mark (Y) and

“FULL” mark (X) on oil level gauge (1). Do not fill

the crankcase above “FULL”  mark (X).

NOTICE

Failure to follow this recommended procedure will

cause the waste particles to be recirculated through

the engine lubrication system with the new oil.

Operating your engine when the oil level is above the

“FULL”  mark could cause your crankshaft to dip into

the oil.  The air bubbles  created from the  crankshaft

dipping into the oil  reduces the oil's lubricating char-

acteristics and could result in the loss of power.

Drain the Engine Oil

After the engine has been run at the normal operating

temperature, stop the engine. Use one of the

following methods to drain the engine crankcase oil:

2. Remove the oil filler cap and add oil, if necessary.

Clean the oil filler cap. Install the oil filler cap.

•   If the engine is equipped with a drain valve, turn

the drain valve knob counterclockwise in order to

drain the oil. After the oil has drained, turn the

drain valve knob clockwise in order to close the

drain valve.

NOTICE

Perkins   oil filters are built to Perkins  specifications.

Use  of  an  oil  filter  not  recommended  by  Perkins

could result in  severe engine damage  to the engine

bearings, crankshaft,  etc.,  as a  result  of the  larger

waste particles from unfiltered oil entering the engine

lubricating system. Only use  oil filters recommended

by Perkins .

1. Remove the oil filter with a suitable tool.

Note: The following actions can be carried out as part

of the preventive maintenance program.

2. Cut the oil filter open with a suitable tool. Break

apart the pleats and inspect the oil filter for metal

debris. An excessive amount of metal debris in the

oil filter may indicate early wear or a pending

failure.

Illustration 41

g03380736

Use a magnet to differentiate between the ferrous

metals and the nonferrous metals that are found in

the oil filter element. Ferrous metals may indicate

wear on the steel and cast iron parts of the engine.

Typical example

3. Clean the sealing surface of the cylinder block.

4. Apply clean engine oil to the new O ring seal (2).

Nonferrous metals may indicate wear on the

aluminum parts, brass parts, or bronze parts of the

engine. Parts that may be affected include the

following items: main bearings, rod bearings,

turbocharger bearings and cylinder heads.

NOTICE

Do not fill the oil filters with oil before installing  them.

This oil  would not be  filtered and could  be contami-

nated. Contaminated oil can cause accelerated wear

to engine components.

Due to normal wear and friction, it is not

uncommon to find small amounts of debris in the

oil filter. Consult your Perkins  dealer or your

Perkins  distributor in order to arrange for a further

analysis if an excessive amount of debris is found

in the oil filter.

5. Install the new oil filter (1) Spin on the oil filter until

Identificationof a suspect Fuel

Injector

Fuel leaked or spilled onto hot surfaces or electri-

cal components can cause a fire.

Work carefully around an  engine that is running.

Engine parts that  are hot, or  parts that are mov-

ing, can cause personal injury.

Make  sure  that  you wear  eye  protection  at  all

times during testing. When fuel  injection nozzles

are tested, test fluids travel through the orifices of

the  nozzle  tip  with   high  pressure.  Under  this

amount of pressure,  the test fluid can  pierce the

skin and cause serious injury to the  operator. Al-

ways  keep  the  tip  of  the  fuel  injection  nozzle

pointed away from the  operator and into the fuel

collector and extension.

NOTICE

If  your skin  comes  into contact  with high  pressure

fuel, obtain medical assistence immediately.

NOTICE

If a fuel  injector is suspected of operating  outside of

normal parameters it  should be removed by  a quali-

fied technician.  The suspect  fuel injector  should be

taken to an authorised agent for inspection.

NOTICE

Do not allow dirt to enter the fuel system. Thoroughly

clean the area around a  fuel system component that

will be disconnected. Fit a suitable cover over discon-

nected fuel system component.

Operate the engine at a fast idle speed in order to

identify the faulty fuel injector. Individually loosen and

tighten the union nut for the high pressure pipe to

each fuel injector. Do not loosen the union nut more

than half a turn. There will be little effect on the

engine speed when the union nut to the faulty fuel

injector is loosened.

Regular maintenance of the fuel injectors is

recommended by Perkins . The fuel injectors must be

removed and tested by an authorized agent. The fuel

injectors should not be cleaned as cleaning with

incorrect tools can damage the nozzle. The fuel

injectors should be renewed only if a fault with the

fuel injectors occurs. Some of the problems that may

indicate that new fuel injectors are needed are listed

below:

Maintenance Recommendations

Fuel Tank Water and Sediment - Drain

i02335436

Fuel Storage Tanks

Fuel Tank Water and Sediment

- Drain

Drain the water and the sediment from the fuel

storage tank at the following intervals:

•   Weekly

•   Service intervals

•   Refill of the tank

NOTICE

Care  must be  taken to  ensure  that fluids  are  con-

tained  during   performance  of  inspection,   mainte-

nance, testing, adjusting and repair of the product. Be

prepared to  collect the fluid  with suitable containers

before  opening any  compartment  or disassembling

any component containing fluids.

This will help prevent water or sediment from being

pumped from the storage tank into the engine fuel

tank.

If a bulk storage tank has been refilled or moved

recently, allow adequate time for the sediment to

settle before filling the engine fuel tank. Internal

baffles in the bulk storage tank will also help trap

sediment. Filtering fuel that is pumped from the

storage tank helps to ensure the quality of the fuel.

When possible, water separators should be used.

Dispose of all fluids according to local regulations and

mandates.

Fuel Tank

Fuel quality is critical to the performance and to the

service life of the engine. Water in the fuel can cause

excessive wear to the fuel system.

i02813964

Hoses and Clamps - Inspect/

Replace

Water can be introduced into the fuel tank when the

fuel tank is being filled.

Condensation occurs during the heating and cooling

of fuel. The condensation occurs as the fuel passes

through the fuel system and the fuel returns to the

fuel tank. This causes water to accumulate in fuel

tanks. Draining the fuel tank regularly and obtaining

fuel from reliable sources can help to eliminate water

in the fuel.

Inspect all hoses for leaks that are caused by the

following conditions:

•   Cracking

•   Softness

Drain the Water and the Sediment

•   Loose clamps

Fuel tanks should contain some provision for draining

water and draining sediment from the bottom of the

fuel tanks.

Replace hoses that are cracked or soft. Tighten any

loose clamps.

NOTICE

Open the drain valve on the bottom of the fuel tank in

order to drain the water and the sediment. Close the

drain valve.

Do not bend or  strike high pressure lines. Do not  in-

stall bent  or damaged lines,  tubes or hoses.  Repair

any loose  or damaged fuel  and oil  lines, tubes  and

hoses. Leaks can cause fires. Inspect all lines, tubes

and  hoses carefully.  Tighten  all connections  to the

recommended torque.  Do not clip  any other  item to

the high pressure lines.

Check the fuel daily. Allow five minutes after the fuel

tank has been filled before draining water and

sediment from the fuel tank.

Fill the fuel tank after operating the engine in order to

drive out moist air. This will help prevent

condensation. Do not fill the tank to the top. The fuel

expands as the fuel gets warm. The tank may

overflow.

Check for the following conditions:

•   End fittings that are damaged or leaking

•   Outer covering that is chafed or cut

Some fuel tanks use supply pipes that allow water

and sediment to settle below the end of the fuel

supply pipe. Some fuel tanks use supply lines that

take fuel directly from the bottom of the tank. If the

engine is equipped with this system, regular

•   Exposed wire that is used for reinforcement

•   Outer covering that is ballooning locally

•   Flexible part of the hose that is kinked or crushed

•   Armoring that is embedded in the outer covering

maintenance of the fuel system filter is important.

Maintenance Recommendations

Radiator - Clean

A constant torque hose clamp can be used in place of

any standard hose clamp. Ensure that the constant

torque hose clamp is the same size as the standard

clamp.

Note: For the correct coolant, see this Operation and

Maintenance Manual, “Fluid Recommendations”.

8. Refill the cooling system. Refer to the OEM

information for further information on refilling the

cooling system.

Due to extreme temperature changes, the hose will

harden. Hardening of the hoses will cause hose

clamps to loosen. This can result in leaks. A constant

torque hose clamp will help to prevent loose hose

clamps.

9. Clean the cooling system filler cap. Inspect the

cooling system filler cap's seals. Replace the

cooling system filler cap if the seals are damaged.

Install the, cooling system filler cap.

Each installation application can be different. The

differences depend on the following factors:

10. Start the engine. Inspect the cooling system for

leaks.

•   Type of hose

•   Type of fitting material

i02335774

•   Anticipated expansion and contraction of the hose

Radiator - Clean

•   Anticipated expansion and contraction of the

fittings

The radiator is not usually supplied by Perkins . The

following text describes a typical cleaning procedure

for the radiator. Refer to the OEM information for

further information on cleaning the radiator.

Replace the Hoses and the Clamps

Refer to the OEM information for further information

on removing and replacing fuel hoses (if equipped).

Note: Adjust the frequency of cleaning according to

The coolant system and the hoses for the coolant

system are not usually supplied by Perkins . The

following text describes a typical method of replacing

further information on the coolant system and the

hoses for the coolant system.

the effects of the operating environment.

Inspect the radiator for these items: Damaged fins,

corrosion, dirt, grease, insects, leaves, oil and other

debris. Clean the radiator, if necessary.

Personal injury can result from air pressure.

Pressurized System: Hot coolant can  cause seri-

ous burns. To open the cooling system filler cap,

stop the engine and wait until the cooling system

components are cool. Loosen the cooling system

pressure   cap  slowly   in  order   to   relieve  the

pressure.

Personal injury can result without following prop-

er  procedure. When  using  pressure air,  wear  a

protective face shield and protective clothing.

Maximum air pressure at the nozzle must be less

than 205 kPa (30 psi) for cleaning purposes.

1. Stop the engine. Allow the engine to cool.

Pressurized air is the preferred method for removing

loose debris. Direct the air in the opposite direction to

the fan's air flow. Hold the nozzle approximately 6 mm

(0.25 inch) away from the radiator fins. Slowly move

the air nozzle in a direction that is parallel with the

radiator tube assembly. This will remove debris that is

between the tubes.

2. Loosen the cooling system filler cap slowly in order

to relieve any pressure. Remove the cooling

system filler cap.

Note: Drain the coolant into a suitable, clean

container. The coolant can be reused.

3. Drain the coolant from the cooling system to a level

that is below the hose that is being replaced.

Pressurized water may also be used for cleaning. The

maximum water pressure for cleaning purposes must

be less than 275 kPa (40 psi). Use pressurized water

in order to soften mud. Clean the core from both

sides.

4. Remove the hose clamps.

Use a degreaser and steam for removal of oil and

grease. Clean both sides of the core. Wash the core

with detergent and hot water. Thoroughly rinse the

core with clean water.

5. Disconnect the old hose.

6. Replace the old hose with a new hose.

7. Install the hose clamps with a torque wrench.

Maintenance Recommendations

Starting Motor - Inspect

If the radiator is blocked internally, refer to the OEM

Manual for information regarding flushing the cooling

system.

NOTICE

For any type  of leak (coolant, lube, or fuel)  clean up

the fluid.  If leaking is  observed, find the source  and

correct the leak. If leaking is suspected, check the flu-

id levels more often than recommended until the leak

is found  or fixed,  or until  the suspicion  of a  leak is

proved to be unwarranted.

After cleaning the radiator, start the engine. Allow the

engine to operate at low idle speed for three to five

minutes. Accelerate the engine to high idle. This will

help in the removal of debris and the drying of the

core. Slowly reduce the engine speed to low idle and

then stop the engine. Use a light bulb behind the core

in order to inspect the core for cleanliness. Repeat

the cleaning, if necessary.

NOTICE

Accumulated grease and/or oil on an  engine is a fire

hazard. Remove the accumulated grease and oil. Re-

fer to  this Operation and  Maintenance Manual, “En-

gine - Clean” for more information.

Inspect the fins for damage. Bent fins may be opened

with a “comb”. Inspect these items for good condition:

Welds, mounting brackets, air lines, connections,

clamps and seals. Make repairs, if necessary.

•   Ensure that the cooling system hoses are correctly

clamped and that the cooling system hoses are

tight. Check for leaks. Check the condition of all

pipes.

i02177969

Starting Motor - Inspect

•   Inspect the water pump for coolant leaks.

Perkins  recommends a scheduled inspection of the

starting motor. If the starting motor fails, the engine

may not start in an emergency situation.

Note: The water pump seal is lubricated by the

coolant in the cooling system. It is normal for a small

amount of leakage to occur as the engine cools down

and the parts contract.

Check the starting motor for correct operation. Check

the electrical connections and clean the electrical

connections. Refer to the Systems Operation, Testing

and Adjusting Manual, “Electric Starting System -

Test” for more information on the checking procedure

and for specifications or consult your Perkins  dealer

or your Perkins distributor for assistance.

Excessive coolant leakage may indicate the need to

replace the water pump seal. For the removal of the

water pump and the installation of water pump and/or

seal, refer to the Disassembly and Assembly Manual,

“Water Pump - Remove and Install” for more

information or consult your Perkins dealer or your

Perkins  distributor.

i02177973

•   Inspect the lubrication system for leaks at the front

crankshaft seal, the rear crankshaft seal, the oil

pan, the oil filters and the rocker cover.

Walk-Around Inspection

•   Inspect the fuel system for leaks. Look for loose

fuel line clamps and/or tie-wraps.

Inspect the Engine for Leaks and

for Loose Connections

•   Inspect the piping for the air intake system and the

elbows for cracks and for loose clamps. Ensure

that hoses and tubes are not contacting other

hoses, tubes, wiring harnesses, etc.

A walk-around inspection should only take a few

minutes. When the time is taken to perform these

checks, costly repairs and accidents can be avoided.

For maximum engine service life, make a thorough

inspection of the engine compartment before starting

the engine. Look for items such as oil leaks or coolant

leaks, loose bolts, worn belts, loose connections and

trash buildup. Make repairs, as needed:

•   Inspect the alternator belts and any accessory

drive belts for cracks, breaks or other damage.

Belts for multiple groove pulleys must be replaced as

matched sets. If only one belt is replaced, the belt will

carry more load than the belts that are not replaced.

The older belts are stretched. The additional load on

the new belt could cause the belt to break.

•   The guards must be in the correct place. Repair

damaged guards or replace missing guards.

•   Wipe all caps and plugs before the engine is

serviced in order to reduce the chance of system

contamination.

Maintenance Recommendations

Water Pump - Inspect

•   Drain the water and the sediment from the fuel

tank on a daily basis in order to ensure that only

clean fuel enters the fuel system.

•   Inspect the wiring and the wiring harnesses for

loose connections and for worn wires or frayed

wires.

•   Inspect the ground strap for a good connection

and for good condition.

•   Disconnect any battery chargers that are not

protected against the current drain of the starting

motor. Check the condition and the electrolyte

level of the batteries, unless the engine is

equipped with a maintenance free battery.

•   Check the condition of the gauges. Replace any

gauges that are cracked. Replace any gauge that

can not be calibrated.

i01907756

Water Pump - Inspect

A failed water pump may cause severe engine

overheating problems that could result in the following

conditions:

•   Cracks in the cylinder head

•   A piston seizure

•   Other potential damage to the engine

Note: The water pump seal is lubricated by the

coolant in the cooling system. It is normal for a small

amount of leakage to occur as the engine cools down

and parts contract.

Visually inspect the water pump for leaks. Renew the

water pump seal or the water pump if there is an

excessive leakage of coolant. Refer to the

Disassembly and Assembly Manual, “Water Pump -

Remove and Install” for the disassembly and
