Replace your twin-turbo BMW's electric water pump BEFORE it experiences catastrophic failure!

BMW changed to an electric pump to reduce emissions and make the engine more efficient. Pumps driven from the main drive belt used up fuel which made for more emissions. Electric pumps only work when they are needed and only require the alternator to supply power. Because the engine computer regulates engine temperatures, the water pump only needs to work when it has to (including after the car has been turned off). In theory this should make the pump last longer. But it's the electronics inside that fail and will force a replacement, often without warning. Depending on operating conditions the engine may go into limp mode and require a tow! Although if you are religious about oil changes and checking/clearing fault codes you may get a soft (hidden) code for low water pump output ahead of time.

This package is made up of all OEM replacement water pump and thermostat parts for the 2007+ models with the N54 twin-turbo engine. The pump itself is a Genuine BMW, so you are assured the highest quality manufacturing on your replacement pump. This particular kit does not include the water hose connecting the pump to the thermostat (it's not always needed). We favor OEM parts to cheaper alternatives because of better build quality and a two year warranty (most aftermarket brands only give one year).

Please note: This kit is NOT for the N55 "TwinPower" single turbo models, found from 2011 forward. If your car is a 2011 or newer model, please make sure it has the N54 engine, which is a tru twin turbo configuration. Models like the 1M Coupe, 335is and Z3 35is used the N54 engine after 2010, while models like the 335i and 335xi stopped using the N54 engine after the 2010 model year. Please be sure your car has an N54 before ordering. 

We also recommend a gallon of engine coolant and the u-shaped connecting hose, which may also be ordered from the related items found below.
