Water Pump with Support, BMW - F22 230i, F3X 330i/430i, G30 530i, G01 X3, G02 X4

OE BMW water pump, pulley, flow control flap, vacuum actuator, with support bracket 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 assembly with the pump and bracket (shown here) and with the water pump kit on its own (part #11518638026). The pump can be replaced on its own without the support bracket.

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.
