- Fail Stuck Open
Fail Stuck Closed
Your Thermostat should be open up when your car engine heats up and allow coolant to flow from radiator to engine. If your thermostat is also not working properly and there is no coolant flow through your car heater radiator then it must be stuck closed.
The thermostat controls the temperature of fluids from hoses and the radiator. That is the reason the thermostat causes the car to overheat.
Fail Stuck Open
If the thermostat is stuck in an open position and then the continuous flow of coolant will start from the radiator that can cause the engine to cold. If your engine is over-cooled then it will take more fuel consumption to run properly.
Fault Heater Fans
