Good To Know

Q: Should the housing surfaces be cleaned before installing this gasket? A: Yes, remove all old gasket material and debris from both mating surfaces so the new gasket seats evenly. Clean, flat surfaces help prevent coolant leaks after assembly.

Q: Is this gasket reusable? A: No, gaskets are single-use items and should be replaced each time the housing is removed. Reusing a compressed gasket risks leaks under cooling system pressure.

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