Thermostat

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.  How can you tell if it is working properly?  You can tell by watching the gauges in your car.   If your gauge goes red within the first 15 minutes your thermostat may be bad and need replacing.  Shop our webstore for quality thermostats for your GM vehicle.
