How to adjust the timing belt on an Audi 80?

I have noticed a strange noise coming from my engine and was advised to check and possibly adjust the timing belt on my Audi 80. Can someone provide steps on how to properly adjust the timing belt?

First and foremost, make sure you have all the necessary tools and equipment before attempting to adjust the timing belt.

Start by removing the engine cover to gain access to the timing belt. Be careful not to damage any other components while doing so.
