Town & Country V6-3.8L (2009)
Water Pump - Inspection
3.3/3.8L ENGINE
Replace the water pump if it has any of the following defects:
-
Damage or cracks on the pump body.
-
Coolant leaks; this will be evident by a wet stream of coolant running down the pump body and components below. A thin stain below the weep
hole reservoir slot is considered normal operation.
-
Impeller rubs inside of chain case cover.
-
Excessively loose or rough turning bearing.
NOTE: A weepage stain that is black, brown, or grey is considered normal, if it is dry. If the weep appears wet; pressure test the cooling
system at 15-18 psi and observe the weep area. If weep area remains unchanged, do not replace the water pump for this condition.
Replace the water pump, if a steady flow of engine coolant is evident from the weep hole/reservoir slot (shaft seal failure). Be sure to
perform a thorough analysis before replacing water pump.
