Your cooling system is the lifeline of your engine. When a water pump bearing starts whining or the thermostat cracks and leaks, you need a replacement you can actually trust. Cheap aftermarket pumps are notorious for failing early, which is why we strictly supply genuine, tested OEM units for the grafters who want to do the job once and do it right.

This is a genuine BMW water pump (manufactured by OEM supplier Saleri) carrying the part number 8514458, removed from a running B47 donor engine. It is supplied exactly as pictured, complete with the drive pulley and the attached black plastic thermostat housing.

Every cooling component that hits our bench goes through a strict visual and physical check. We manually spin the pulley to ensure the bearing is smooth with no excessive play, we inspect the metal impeller for cavitation damage, and we check the plastic thermostat housing for hairline cracks. It’s a proper, solid part ready to get your workhorse back on the road safely.

We always recommend fitting a new gasket when installing a salvaged water pump to ensure a perfect seal.
