How do I diagnose and fix a coolant leak in my Audi 80?

I've noticed that my Audi 80 is losing coolant, but I'm not sure where the leak is coming from. What steps should I take to identify and repair the leak? Is it something I can fix myself or do I need to take it to a mechanic?

First, check all of the hoses and connections in the cooling system for any visible signs of leakage. If you don't see any obvious issues, you may have a leak in the radiator or water pump. These are more complex repairs and may require professional help. However, if you're confident in your skills, you can try replacing the faulty part yourself. Just make sure to properly drain and refill the coolant.

If you notice a sweet smell inside your car or see white smoke coming from the exhaust, it's likely that you have a leak in the head gasket. This can be a tricky fix and may require specialized tools. Consider taking your Audi to a mechanic for this repair.
