Water Pump - Inspect
Note: If engine coolant enters the engine lubricating
system, the lubricating oil and the engine oil filter
must be replaced. Draining will remove any
contaminate and will prevent any irregular oil
samples.
In order to install a new water pump, refer to the
Disassembly and Assembly Manual, "Water Pump -
Remove and Install".
