BMW Information | Auxiliary Drive Belt Positioning - M43TU - E46

Reference for the correct fitting position of the drive belt on M43TU or M43B19 e46 BMW engines.

The placement of the drive belt becomes unclear once it's taken off, and there are no clear instructions on how to loop it around the different pulleys. This could pose a challenge if you need to replace the belt unexpectedly, either while on the road or at home. To prepare for such an emergency breakdown situation, you can print out this image and keep it in your vehicle's glovebox.
