This is a genuine BMW water hose, part number 17 11 1 723 521. The number stamped on the part is 17111723521; BMW's catalog files it under the short number 1723521. You will find it on our Cooling System shelf, under Radiator with mounting. It supersedes the older number 1723700, so a part carrying that number is the same part.

It fits the E36 sedan, coupe, convertible and touring (320i, 323i, 325i, 328i and M3, 1992–1999), with the M50, M52, S50 or S52 engines — and the European-market versions.

BMW draws it on 2 diagrams, among them Radiator/Expansion Tank/Frame (17_0093) and Radiator/Expansion Tank/Frame (17_0960). It weighs about 70 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.
