Radiator cap — a genuine BMW part, number 17 11 7 639 022. The number stamped on the part is 17117639022; BMW's catalog files it under the short number 7639022. You will find it on our Cooling System shelf, under Radiator with mounting. It supersedes the older number 1742231, so a part carrying that number is the same part.

It fits every E36 body style (318i, 318ti, 320i, 323i, 325i and 328i, 1992–1999), with the M42, M43, M44, M50 or M52 engines — and the European-market versions.

BMW draws it on 28 diagrams, among them Expansion tank, manual gearbox (17_0140) and Expansion tank, automatic gearbox (17_0141). It weighs about 60 g (0.1 lb).

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