How can I troubleshoot a coolant leak in my Audi 80?

I've noticed a small puddle of coolant under my car and I suspect it could be a leak. What are the possible causes and how can I fix it?

The most common cause of coolant leaks in Audi 80s is a faulty water pump. Check for any signs of leakage around the water pump and replace it if necessary. Don't forget to refill the coolant after replacing the pump.

Another potential cause of coolant leaks is a cracked radiator. Check for any visible cracks or damage to the radiator and replace it if needed. Make sure to thoroughly bleed the air out of the cooling system after replacing the radiator.

It's also possible that the coolant leak is coming from a damaged or worn-out hose. Inspect all your hoses and replace any that are leaking, cracked, or brittle. Don't forget to check the clamps and make sure they are tight.
