Note: The water pump seals are lubricated by the
coolant in the cooling system. It is normal for a small
amount of leakage to occur. Refer to illustration 63
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 will remove any contamination that
is caused by the coolant and this 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
