BMW X5 Waterpump

Had this BMW X5 with the 4.4L motor come in this last week with a squeaking noise from the front of the engine. Luckily the owner is on top of stuff like this, and caught this early as it was the bearing in the waterpump starting to make noise. After pulling the belt, the pulley was starting to get play in the bearing, so it was time to replace! Not bad for 135k miles on the original pump! Can’t say that about BMW waterpumps very often 🙂

Waterpump is located front center of the motor, remove the fan shroud, hoses, belts, etc. You also must remove the crankshaft pulley in order for the waterpump to be removed.

Good time to replace the thermostat while in there.

And crank pulley removed and waterpump off the engine.

And the new waterpump ready to go on. The job is pretty straight forward, just messy 🙂 It is always nice to catch these pumps failing early rather than stranding a customer on the side of the road!

That was too easy….

Fully expected to see the splintered remains of a plastic coolant hose connector that had fused to the radiator.
