OE BMW water pump, pulley, flow control flap, and vacuum actuator for 2016+ F22 230i, F3X 330i/430i, G30 530i, G01 X3, G02 X4 models with the 4-cylinder turbo engine (B46). BMW lists the water pump two ways - the pump itself (shown here) and with the bracket and housing behind it (part #11517644809). You can replaces the pump itself with this kit. But the entire assembly is also available if you need a more extensive overhaul.

The mechanical water pump on the B46 engine is essentially a wear item. With enough miles, stress, and age/time, eventually the water pump will fail and create a coolant leak or engine overheating situation that will leave you broken down. And cooling requirements on modern cars are higher than ever leaving water pump with more cooling demands than other designs.

Fitment note: 530i, X1/X2, or X3/X4 only up to 2019 model year (not for 2020+).

This is a Genuine BMW Water Pump with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
