Water Pump - Inspect
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.
•
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.
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
assembly procedure.
