Hose f water valve and left radiator – BMW diagram09 View BMW DiagramSee this part on the official exploded view

This is a genuine BMW hose f water valve and left radiator, part number 64 21 8 377 663. The number stamped on the part is 64218377663; BMW's catalog files it under the short number 8377663. You will find it on our AC & Climate Control shelf, under Other Heater and Air Conditioning parts. It supersedes the older number 8390316, so a part carrying that number is the same part.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on the Water valve/Water hose (64_0621) diagram. It weighs about 139 g (0.3 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
