GM Thermostats

Your GM's thermostat is what helps to regulate the flow of coolant through your engine, ensuring that it operates at peak performance. The engine has to be at the right temperature to perform effectively - not too hot, and not too cold. The opening and closing of the thermostat is what helps bring coolant in to your engine space or prevent it from circulating if the engine is sufficiently cooled. The flow of coolant and use of other cooling system parts helps keep your engine functioning as it should! A failing thermostat can cause more problems down the line and cause you more repairs and stress down the line. This is why replacing a thermostat as soon as you notice signs of trouble is so important! Some symptoms of a failing car thermostat can include the obvious, like overheating of the engine. A thermostat stuck in the closed position is something that can lead to issues with coolant from the radiator. You might also notice that the temperature of the engine fluctuates often. Thermostat wear and tear can also cause poor engine performance in your GM, reducing gas mileage and causing damage over time. You can find OEM replacement thermostats for your make and model here on our site.
