How to Fix an Overheating Engine in My Audi 80?

I've noticed that my Audi 80's engine is overheating frequently. What could be the possible cause of this and how can I fix it?

The most common cause of an overheating engine in an Audi 80 is a malfunctioning cooling system. Check the coolant level and if it's low, top it up with a 50/50 mixture of coolant and water. If the coolant level is fine, then there might be a leak in the cooling system which needs to be repaired.

Another possible cause for an overheating engine in an Audi 80 is a faulty thermostat. It's responsible for regulating the flow of coolant through the engine. If it's not functioning properly, it can cause the engine to overheat. Consider replacing the thermostat if it's not working correctly.
