• 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.

(A) Weep hole
(B) Vent hole
Note:
The water pump seals are lubricated by the
coolant in the cooling system. A small amount of
leakage will occur normally. Refer to illustration 69 for
the position of the weep hole and the vent hole.
Visually inspect the water pump for leaks.
Note:
If engine coolant enters the engine lubricating
system, the lubricating oil and the engine oil filter
must be replaced. This operation will remove any
contamination that is caused by the coolant and this
action will prevent any irregular oil samples.
The water pump is not a serviceable item. In order to
install a new water pump, refer to the Disassembly
and Assembly Manual, “Water Pump - Remove and
Install”.
