What Can Cause the Audi 80's Engine to Overheat?

I've noticed that my Audi 80's engine has been running hot lately, reaching temperatures over 100 degrees Celsius. I've also noticed a decrease in engine performance. What are some potential causes for these symptoms and how can I prevent them?

The main cause of engine overheating in an Audi 80 is a malfunctioning cooling system. This can be caused by low coolant levels, a faulty radiator, or a broken water pump. It is important to regularly check and maintain these components to prevent engine overheating. If you notice any leaks or abnormal temperatures, it is best to have your vehicle inspected by a professional mechanic.

Another potential cause of engine overheating in an Audi 80 is a faulty thermostat. The thermostat regulates the flow of coolant to the engine and if it is stuck closed or open, it can lead to overheating. If your engine temperature gauge is fluctuating, it may be time to replace the thermostat.
