So I bought a Continental belt from ECS and swapped out the old one, only to find that it was 2-3cm too big. So I decided to deal with it for a month and then today I decided I had had enough. So I went to Canadian tire to buy one and surprisingly they had 1 Certified brand belt in stock. Get home only to find out it fits the same as the Continental. The Continental is 10 x 965mm and the Certified is an 11 x 965mm. Any ideas as to why this could be? Also "yes" I have it around both the fan, alt, and crank pulley. I'm at the point that I'm considering extending the tensioner bracket a few cm. As a side note the car is a 85' 325e running with Motronic 1.3 w/ 87' hardware. ie alt, tensioner (it was less rusty) and crank pulley. From what I see on RealOEM and other sites it makes no difference. Any help would be appreciated.

New Alt + Fan Belt loose
When you tried the 10mm smaller did you loosen the alternator gear bolt thing? You are supposed to loosen it then fit the belt then tighten it. Mine was messed up so I undid one of the pulleys and slipped the belt over the pulley then got the pulley to line up and it was perfect.BMW tech
