W ater Pump - Inspect
•
Inspect the lub
rication system for leaks at the front
crankshaft seal, the rear crankshaft seal, the oil
pan, the oil filters and the rocker cover.
•
Inspect the fuel system for leaks. Look for loose
fuel line clamps and/or tie-wraps.
•
Inspect the piping for the air intake system and the
elbows for cracks and for loose clamps. Ensure
that hoses a
nd tubes are not contacting other
hoses, tubes, wiring harnesses, etc.
•
Inspect the
alternator belts and any accessory
drive belts for cracks, breaks or other damage.
Belts for m
ultiple 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 b
elts 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
protec
ted against the current drain of the starting
motor. Check the condition and the electrolyte level
of the batteries, unless the engine is equipped with
amain
tenance free battery.
•
Check the condition of the gauges. Replace any
gauge
s that are cracked. Replace any gauge that
can not be calibrated.

ove
rheating problems that could result in the following
conditions:
•
Cra
cks in the cylinder head
•
Apistonseizure
•
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 cont
ract.
Visually inspect the water pump for leaks. Renew
the water pum
p seal or the water pump if there
is an excessive leakage of coolant. Refer to the
Disassembly and Assembly Manual, “Water Pump
