Factory GM Thermostats

Thermostats were designed to help prevent your engine from overheating-- but how do they work? A spring opens and closes the thermostat, which lets coolant circulate between the engine and the radiator. Your coolant will move in the right temperature range, no matter how hot or cold the weather is.

Although thermostat failure is rare, the easiest way to tell if you need to change it is by looking at the temperature gauge. If the needle is in the center or in the cold range lightly, it's in good working condition. If, for some reason, your thermostat is not working properly, you can check for the warning signs. They include a lit Check Engine light, valve operation issues, engine problems, or AC or heating system malfunctions. If you come across any of these issues, it's best to perform a vehicle inspection.
