How to fix a faulty thermostat in an Audi 80?

I've noticed that my Audi 80's thermostat is not working properly. The temperature gauge constantly reads high and the engine seems to overheat quickly. Is there a way to fix this issue on my own or do I need to take it to a mechanic?

Hi Emily, it sounds like your thermostat may be stuck closed. This is a common issue in older Audi 80 models. The first step would be to check the thermostat housing for any leaks or cracks, as this can cause it to malfunction. If everything looks fine, then the thermostat will need to be replaced. You can find a replacement thermostat at any auto parts store and it shouldn't be too difficult to replace yourself. Just make sure to consult your Audi 80's manual for specific instructions.
