Good To Know

Q: Does this gasket require sealant during installation? A: Most installs rely on a clean, dry mating surface, though some technicians add a thin film of suitable sealant. Always follow the service manual procedure for your model.

Q: Can this gasket be reused after removal? A: Gaskets are designed for single-use sealing and should be replaced each time the housing is separated. Reusing one risks coolant leaks and overheating.

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