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 OE or OEM replacement water pump and thermostat parts for the 2007+ models with the N54 twin-turbo engine. We favor OEM parts to cheaper alternatives because of better build quality and a two year warranty (most aftermarket brands only give one year).

Engine coolant and the hose may also be ordered using the options below.
