OEM GM Thermostats

The thermostat on your GM vehicle is made to regulate the temperature in your engine, so you never run too hot or too cold. Should you notice a change in your temperature gauge, 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.
