Water Pump Clean and Inspect

WATER PUMP CLEAN AND INSPECT





1. Remove the old gasket material from the water pump sealing surfaces.
Refer to Replacing Engine Gaskets.
2. Clean all excess dirt and debris from the water pump housing.
3. Inspect the water pump for the following:
^ Gasket sealing surfaces for excessive scratches or gouging
^ Restrictions within the internal coolant passages
^ Excessive side-to-side play in the pulley shaft
^ Leakage at the water outlet housing or rear cover gasket
^ Leakage at the water pump vent hole
A stain around the vent hole is acceptable. If leakage occurs (dripping) with the engine running and the cooling system pressurized, replace the water pump.
