How to fix a leaking radiator on an Audi 80?

My Audi 80 has been leaking radiator fluid and I'm not sure how to fix it. It seems to be coming from the bottom of the radiator. Any advice would be appreciated!

First, check the radiator hose and clamps for any cracks or leaks. If they are in good condition, the leak may be coming from the radiator itself. Try using a radiator sealant to fix the leak.

You may need to replace the radiator if the sealant doesn't work. This is a fairly simple task and can save you from further leaks. Make sure to properly dispose of the old radiator.

Check your coolant levels regularly to prevent leaks. Low coolant levels can cause overheating, which can lead to radiator leaks. Also, make sure to flush and refill your coolant every year.
