How do you replace the belts on a 99 bmw 323i?
The 323 comes with one serpentine belt that runs all the above. Changing the belt is a frickin’ nightmare. The tensioner is supposed to loosen ‘quiet easily’ if you have a correct tool, which most 323’s seem to be missing from the little tool kit on the trunk lid, plus you might need to remove the radiator cowl and fan (!) to reach all the parts. Go to the first link, and save the diagram (hopefully in color) – Print it out and laminate it if you must. The pattern of the belt is very important, and if you also have a/c, you will need to remove that belt before placing the main belt on. http://www.bimmerwerkz.com/forum/3-serie… This link has some decent photos, though I tend to think that either my car is out to drive me insane (pun intended), or it really is that easy:
