so i got this other prob with my e30, but its not a fan motor prob
the alternator belt i got from bimmer specialist was replaced with original. However, after a few kilometres of driving her the belt break off. So i installed another one and it broke off again. After installing the belt there was some squeekyin for a second or two when turning engine on. This happened to me twice, so i installed back the original belt that came with the car and its perfect. Can someone tell me what the problem is?
