Specs At A Glance

Good To Know

Q: Does this gasket require sealant during installation? A: Most water pump housing gaskets install dry, but a thin film of gasket sealant can be used if the mating surfaces are not perfectly smooth. Always torque fasteners to specification.

Q: Should I replace other gaskets at the same time? A: If you are already removing the water pump housing, inspecting and replacing related seals or O-rings is a practical step. This helps avoid repeat labor later.

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