03 View BMW DiagramSee this part on the official exploded view→This is a genuine BMW radiator cap, part number 17 11 7 639 021. The number stamped on the part is 17117639021; BMW's catalog files it under the short number 7639021. You will find it on our Cooling System shelf, under Radiator with mounting. It supersedes the older number 7516004, 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 11 diagrams, among them Cooling water expansion tank (17_0272) and Expansion Tank/Tubing (17_0343). It weighs about 90 g (0.2 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
