Good To Know

Q: When should a water pump housing gasket be replaced? A: Replace it any time the pump housing is removed, or if you notice coolant weeping at the housing joint. Reusing a compressed gasket risks a persistent leak.

Q: Is sealant needed with this gasket? A: It is made to seal once the housing is tightened to specification, so sealant is generally unnecessary. Keep the mating surfaces clean and dry during installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
