01 View BMW DiagramSee this part on the official exploded view→This is a genuine BMW ribbed v-belt, part number 11 28 7 636 378. The number stamped on the part is 11287636378; BMW's catalog files it under the short number 7636378. You will find it on our Engine shelf, under Other Engine parts. It supersedes the older number 1437929, so a part carrying that number is the same part.
It fits every E36 body style (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 10 diagrams, among them Belt Drive Water Pump/Alternator (11_1344) and Belt Drive Water Pump/Alternator (11_1399). It weighs about 160 g (0.4 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
