Audi 90 Thermostat replacement
When do Audi 90 thermostats need to be replaced?
A car's thermostat is part of the Audi 90's cooling system, the thermostat regulates the engine’s operating temperature and flow of coolant circulation through the engine.
It keeps your Audi 90's engine at the optimum running temperature so the engine has time to warm up on startup and also cool down when it is hot.
The thermostat is a valve that opens and closes to allow or deny coolant flow. When a thermostat fails it can get stuck open or closed. This can cause the engine to overheat.
Audi 90 thermostats can fail due to a defect, old age, overheating, and sludge buildup. If it does malfunction it can lead to serious problems and should be replaced as soon as an issue is detected.
