Water Pump (Genuine BMW) - E9X M3, E6X M5/M6

Chronic water pump failures are a thing of the past but it's still a wear and tear item that will need to be replaced at some point. For the M3 S65 V8 and M5/M6 S85 V10 it's best to plan a complete cooling overhaul in advance and a water pump must be on your list. This is the Genuine BMW replacement water pump with a new o-ring.

Don't forget that now is the best time to also replace the thermostat.
