Step 1 - Purchase Parts

You will need the following parts and supplies to perform this repair.

Water Pump

The water pump on your BMW takes a pounding...not only is it mounted against the engine block but it has to pump thousands of gallons of hot coolant through its lifespan. These brutal conditions take a toll on the mechanical parts so only the best built water pumps survive! This Genuine BMW water pump is the same factory unit that would be installed at the dealership. Don't get sucked in by cheaper aftermarket water pumps...they are not built the same as a factory pump
