This is a package with an OEM electric water pump and thermostat for the N20/N26 4-cylinder engine used on F22 228i, 228ix (2014, 2015), F30 320i, 328i (2012, 2013, 2014, 2015), F32/F33 428i (2014, 2015), F10 528i (2012, 2013, 2014, 2015, 2016), E84 X1 28i (2013, 2014, 2015), F25 X3 28i (2012, 2013, 2014, 2015, 2016, 2017), F26 X4 28i (2015, 2016, 2017, 2018), and E89 Z4 28i (2012, 2013, 2014, 2015, 2016), including xDrive models. 

The water pump is an electrical component now and is controlled by the engine computer. It only works when it has to, including even when the engine is shut off. This reduces fuel consumption and has less parasitic drag on the engine. Failures are usually caused by the electronics inside the pump so there is almost no warning of an impending failure or early signs of overheating. One of the only warning signs of electric water pump failure is if the electric fan suddenly starts working all of the time at its highest speed. This is because the pump has stopped, or not responding, and the fans are kicking in to take up the slack. Depending on operating conditions you may only have minutes before the engine shuts off to prevent serious overheating.

There is more to these parts than just a pump and thermostat. There is a hose that connects them both (BMW part #11538645481) as well as many other hoses that could also be replaced at the same time. See below for Related Items. New water pump mounting bolts are not required but available if you want to replace them.

These are OEM cooling components manufactured by the original suppliers to BMW for these parts, as well as many other cooling parts. 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. These parts have a two year warranty.
