Good To Know

Q: Does this gasket need sealant during installation? A: Most water pump housing gaskets of this type install dry unless the service manual specifies otherwise. Follow your model's torque and assembly procedure for best results.

Q: How do I know if the housing gasket has failed? A: Coolant weeping around the pump housing or a dropping coolant level often points to a failed gasket. Confirm the leak source before ordering a replacement.

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