-- View BMW DiagramSee this part on the official exploded view→Belt tensioner — a genuine BMW part, number 64 55 7 786 076. The number stamped on the part is 64557786076; BMW's catalog files it under the short number 7786076. You will find it on our AC & Climate Control shelf, under Condenser, air conditioning. It supersedes the older number 2354037, so a part carrying that number is the same part.
It fits the E46 sedan and touring (318d, 320d and 330d, 1998–2002), with the M47 or M57 engines.
BMW draws it on 8 diagrams, among them Belt Drive Climate Compressor (11_3574) and Belt Drive Climate Compressor (11_3576). It weighs about 557 g (1.2 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
