How can I check the coolant level on my Audi 80?

I've noticed my Audi 80's temperature gauge fluctuating and I suspect the coolant level may be low. How can I check and add more coolant if needed?

To check the coolant level on your Audi 80, first make sure the engine is cool. Then, locate the coolant expansion tank in the engine bay and check the level against the minimum and maximum marks on the side.

If the coolant level is below the minimum mark, top it up with a 50/50 mix of water and coolant. Be sure to use the correct type of coolant for your Audi 80's engine.

It's also a good idea to check for any leaks or cracks in the coolant system while you're checking the level. If you notice any, be sure to get them repaired as soon as possible.
