The GMC Sierra, together with its technically identical sibling marketed as the Chevy Silverado, became available for sale back in 1998. Both pickups quickly became popular among North American drivers and were selected as the Truck of the Year multiple times. The Silverado became popular among the buyers who deal with agriculture, while the Sierra was targeted at the individual drivers searching for a convenient utility vehicle to meet their routine needs. The truck is available in several trim levels, so that every buyer can select exactly what is needed.
Everyone knows that excessive heat, which is produced by the engine during its operation, may cause serious damages if not absorbed by the coolant. And, if your gauges show that the temperature in the engine cooling system is above average, the chances are high that your thermostat has failed. When this happens, the thermostat won’t open and the coolant is not able to enter the second cooling circle, so the temperature in the system remains critically high. If you are shopping for GMC Sierra thermostats & components, you are welcome to discover a catalog of these parts in our store. We know that it is important to install a quality thermostat, so we’ve handpicked the parts which are proved to last.
