Water Pump - Removal
3.5L ENGINE
The water pump on all models can be replaced without discharging the air conditioning system.
WARNING: Do not remove pressure cap with the system hot and under pressure because serious burns from coolant can occur.
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 from the weep hole (shaft seal failure). Be sure to perform a thorough analysis before replacing water pump.
