OEM GM Thermostats

Refine Results

The thermostat on your GM vehicle is made to regulate the temperature in your engine, so you don't run too hot or too cold. Should you notice a change in your temperature gauge (or, like we talk about in this article, you are overheating), you may have a failing thermostat. If so, you need a new OEM thermostat.

  • OEM thermostats are made to meet GM's factory standards for performance, so it will be able to handle your model's needs.
  • OEM GM thermostats are made from quality materials that make it last as long as the original thermostat.
  • A GM thermostat is an exact fit replacement part that never needs to be modified in order to get it to fit.

When you buy your OEM GM parts from us, you'll get fast, affordable shipping. Order today and get back on the road.
