GM Thermostats

The thermostat in your vehicle is a vital part of your engine's cooling system. The purpose of the thermostat in your car is to block the flow of coolant to the radiator until your engine is warmed up. When your engine is warmed up the thermostat opens. You can tell by watching the gauges in your car when your engine has reached the correct temperature.  If your gauge goes red within the first 15 minutes your thermostat may be bad and need replacing.If the thermostat is not working properly in your vehicle, it may end up causing engine damage to do erratic coolant temperatures. If you notice your temperature gauge jumping around or see a coolant leak underneath your vehicle, you may have a bad thermostat. You do not want your engine to overheat and leave you stranded on the side of the road, waiting on a tow truck. Shop our webstore here at National GM Parts for genuine OEM thermostats for your GM vehicle. We have replacement thermostats, housings, gaskets, and seals in stock. Be sure to choose your specific GM vehicle to ensure that you have the correct thermostat for your specific vehicle. Find the thermostat you need for your specific GM vehicle below.
