OEM GM Thermostats

Just like in your home, the thermostat helps to regulate the temperature. In your car or truck, it helps to block the coolant as your car heats up. Once it reaches operating temperature, it opens up and allows the coolant to reach the engine.

The thermostat keeps the temperature even because if the engine overheats, it can cause catastrophic damage. This device sits between the radiator and the engine. Because it lets the engine warm up slowly, it reduces any wear and tear on the components.

Should you need to replace the thermostat in your vehicle, get a genuine OEM GM part that is specifically designed to meet the expectations of your vehicle. An Envoy may have different needs than a Silverado 1500, so a genuine GM replacement part for your specific vehicle is a much better choice than a generic aftermarket part. Genuine parts are always going to fit without modification.

You may need to replace the thermostat at some point in your vehicle’s lifetime. These parts are subject to a lot of abuse, so they can start to stick open or closed. If that happens, you are going to have an engine that is too cold or too hot, so replace it as soon as it becomes worn.
