A common failure point on the water pump is a failed thermostat, cracked thermostat housing, or leaking water pump gasket. Because the water pump and thermostat are incorporated into the same housing it's common practice to replace all of the components during service.

This engine coolant thermostat kit includes the thermostat, thermostat housing gaskets, coolant hose O-rings, and all of the seals and hardware needed to fully replace any worn or leaking components related to the engine thermostat.
