How do I replace the serpentine belt on my Audi 80?

I recently noticed some fraying on the edges of my serpentine belt and I'm worried it might fail soon. I want to replace it myself but I'm not sure where to start or what tools I'll need.

Replacing the serpentine belt on an Audi 80 is a fairly straightforward process. You'll need a serpentine belt tool, a wrench or socket set, and a diagram of the belt routing.

First, locate the serpentine belt tensioner and use the tool to release the tension on the belt. Then, carefully remove the belt from each pulley. Take note of the routing so you can replace it correctly.

Before installing the new belt, make sure all the pulleys are clean and free of debris. It's also a good idea to check their alignment to ensure proper operation.
