What is the proper way to change the timing belt on an Audi 80?

I've noticed that my Audi 80 is not running as smoothly as before and I suspect that it is due for a timing belt replacement. However, I'm not sure where to start. Can anyone provide me with step-by-step instructions, including any tools required, for changing the timing belt on my Audi 80?

First, make sure you have all the necessary tools for the job such as sockets, ratchets, and a torque wrench. Then, remove the external components blocking access to the timing belt, such as the alternator and water pump.

After removing the external components, locate the timing marks on the crankshaft and the camshaft. Use these marks to align the timing belt correctly.
