How to Fix a Leaky Radiator in an Audi 80?

My Audi 80's radiator is leaking coolant, causing it to overheat quickly. What can I do to fix this issue and prevent it from happening again?

First, check the radiator hoses for any signs of cracks or wear and tear, as this could be the source of the leak. If the hoses are fine, then it's likely that the radiator itself has a leak. In this case, you can either patch the leak using a radiator sealant or replace the entire radiator. Either way, make sure to add fresh coolant after fixing the leak.

Another common cause of a leaky radiator is a faulty radiator cap. The cap is responsible for maintaining the right pressure in the cooling system, so if it's worn out or broken, it can cause leaks. Replace the cap with a new one and see if that stops the leak. You can also check for any loose connections or damaged seals in the cooling system and fix them accordingly.
