Pierburg brand Electric Waterpump, BMW part number 11517586925, for the E90/E91/E92/E93 non-turbo 3 series (including 2006-2011 model 325i, 325xi, 328i, 328xi, 330i and 330xi -- sedans, coupes, wagons and convertibles), the E60/E61 5 series (including 525i, 525xi, 528i, 528xi, 530i, and 530xi -- sedans and wagons), the E82 128i Coupe and 128i Convertible, Z4 3.0Si and 3.0 sDrive (N52), as well as some X3 models and more.

The electric water pump used on the N52 3.0 liter engine (and N51 SULEV version) is highly prone to failure between 60k and 100k miles. There is almost no warning of an impending failure - the fan constantly runs at 100% and the orange temperature warning light will come on in the cluster (and quickly turn to red followed by limp mode). By this point, your BMW coolant is either about to over boil, or is already steaming out from under your hood. If you're lucky, you're able to shut down the N52/N51 engine before any permanent damage is done.

Don't let this happen to your BMW! If your BMW is well above 60k miles, this pump is a ticking time bomb. It's not if it fails, it's when. Fortunately, replacement is fairly straight forward, and we have replacement electric water pumps from both BMW and the OEM supplier. New mounting bolts are included.

This is an OEM E90 water pump manufactured by Pierburg - the original supplier to BMW for this part, as well as many other electrical components. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
