Packaged by Turner BMW Water Pumps for BMW 1 Series

Clear BMW chassis

The water pump is a known failure point on most BMWs, new and old. Older model BMWs come from the factory with a mechanical fan that features a plastic impeller. If your BMW still has a water pump with a plastic impeller, you should upgrade to one with a metal impeller to avoid future failure. New BMWs utilize an electric water pump that cost BMW millions of dollars to design - when it is working it is great, unfortunately these fail so regularly that we recommend replacing your electric water pump every 60,000 miles to avoid stranding yourself on the side of the road. We have hand selected the best OE suppliers for replacement water pumps so you don't have to pay the high cost of Genuine BMW. However, if you're someone who only puts Genuine BMW parts on your car, we understand - that's why we have those available for you as well.

The stock thermostat is designed to open at 97C. This leaves your engine running fairly hot, and running for quite awhile before your thermostat will begin operation. With the Mishimoto Racing thermostat, the activation temperature becomes 74C. That's 23C cooler, meaning you can rest easy knowing your engine will stay cooler to help avoid all the problems that can be associated with an engine running hot.

This packages covers the major components you would install along with a new water pump or thermostat. On the N54 cars (135i, 335i, 535i) the water pump and theremostat are mounted together. In fact, to get to the thermostat, BMW expects you to remove the water pump. This package covers the whole job. With the electric water pump now an integral part of the efficiency and performance of the engine, staying on top of its maintenance and replacement is the smart thing to do.

Our water pump/thermostat overhaul includes:

OEM VDO electric water pump, p/n 11517588885 or 11517632426
OEM mounting screws for water pump (set of 3), p/n 11517602123
OEM Behr thermostat, p/n 11537549476
Original BMW connecting hose from thermostat to water pump, p/n 11537545665
Original BMW hose clamps for hose (x 2)

The water pump on the N54 engine has more cooling responsibilities than ever before. Not only must it provide cooling for the engine, but it's also pumping fluid used to cool the turbocharger oil and automatic transmission oil. The good news is that the pump only works when, and only as much, as it needs to. The engine computer dictates how much fluid needs to be pumped through the system depending on the load. That means the system can actually stop the pump when warmer temperatures are needed. No longer is the pump spinning all the time from an engine-driven belt. The bad news is that it's now an electrical part, so a failure is usually immediate and with no warning. And if the electronics are at fault, there is no way to rebuild or repair it. Fortunately, the engine computer will force a shut down or reduce power if a problem occurs, preventing catastrophic engine damage.

How to avoid a water pump failure in the future? Replacing the water pump as part of a regular interval schedule will ensure you always have a functioning pump in place. Since this technology is relatively new for BMW, therefore the lifecycle of the pump isn't yet known, we have been recommending replacement every 80-100k miles. This package of OE/OEM parts covers everything with Original BMW coolant offered to finish off the job. A proper bleeding procedure must be followed with the new electric pump.

This water pump package fits the following BMWs with the N54 engine:
2007-2010 E60 BMW 535i 535xi 535i xDrive
2008-2010 E82 BMW 135i
2011-2012 E82 BMW 1M Coupe
2006-2010 E90 BMW 335i 335xi 335i xDrive - Sedan
