How do I fix a leaking coolant tank on my Audi 80?

I have noticed that the coolant tank on my Audi 80 is leaking. How can I fix this issue on my own without going to a mechanic?

First, check the coolant level and make sure it is not too low. If it is low, top it up with the correct type of coolant for your Audi 80. Next, inspect the coolant tank for any cracks or damage. If you see any, you will need to replace the entire tank. If the tank is not damaged, it may just be a loose hose or clamp causing the leak. Tighten any loose connections or replace any damaged hoses.
