The GMC Sierra became a spiritual successor of the aged C/K series trucks, though it was more luxury oriented and featured a wider range of trim levels and optional features than its predecessor. The Sierra was introduced as a distinct model in 1998 and quickly became popular enough to be nominated as the Truck of the Year. It has got a mechanically identical twin, the Chevy Silverado, which was released the same year to follow the corporate tradition of General Motors. The off-road version of the Sierra is the All Terrain trim level, which has got everything needed to explore rugged terrains in remote areas.
In order to operate safely, the internal combustion engine has to be cooled down and the excessive heat needs to be withdrawn by means of the engine cooling system. The coolant, which is usually the combination of antifreeze and water, flows through the hoses to the radiator and on the way, absorbs heat, and the radiator allows the substance to get colder. The thermostat separates two cooling circles, and when the coolant becomes hot enough, the bigger cooling circle comes in play. If you are restoring your full-size pickup and work on its cooling system, you may need GMC Sierra thermostat housing & filler necks. We are proud to offer these products at fair price.
