Cleaning and Inspection

CLEANING
Clean all gasket mating surfaces as necessary.

INSPECTION
Inspect and replace the water pump if it has any of the following defects:
1. Damage or cracks on the pump body.






2. Coolant leaks; if the seal is leaking, this will be evident by traces of thick deposits of dried glycol running down the pump body (3.2/3.5L), pump weep passage (2.7L) , and components below. A thin black stain below pump weep hole/passage is considered normal operation.
3. Impeller rubs inside of cylinder block (2.7L) or timing belt cover (3.2/3.5L) engines.
4. Excessively loose or rough turning bearing.

NOTE: It is normal for the water pump to weep a small amount of coolant from the weep hole (black stain on water pump body). Do not replace the water pump if this condition exists. Replace the water pump if a heavy deposit or a steady flow of engine coolant is evident on water pump body (3.2/3.5L) or from the weep passage (2.7L). This indicates a shaft seal failure and pump must be replaced. Be sure to perform a thorough analysis before replacing water pump.
