This is the coolant return pipe on the back of the water pump on the N62 and N73 engines used in the E53 X5, E60 545/550, E63 645/650, E65 745/750, E70 X5, and F02 750. This pipe connects the water pump to the valley pan and it's a compression fitting (no o-rings). Whenever the water pump or valley pan are replaced this tube should also be replaced.

In the automotive industry the Rein name has quickly come to represent quality. With fitments for some of the worldaEURtms finest automobiles including BMW and Mini and guaranteed OE quality, Rein is a name you can trust.
