you can check your engine codes of the module. Is it seized up? Is your engine getting hot? The module will show pending codes even if your "check engine" light isn't on. Another way to check is a little more simple... 1. take your radiator cap off. 2. do this when the car is cool to avoid injury. 3. turn your car on and let it idle for 10 minutes. see if the water in the radiator starts moving. If it doesn't and your engine temp. gauge starts to rise above normal operating temperature, then you have a faulty thermo stat.
