To run safely and efficiently, the operating temperature of your semi truck's engine must be maintained within a very narrow range. For this reason, your big rig is equipped with a radiator, radiator fan, water pump and other specific parts, which all together form a cooling system. Contrary to popular belief, a cooling system does not only prevent the engine from overheating, but also makes it possible to significantly improve its warm-up time, resulting in reduced fuel consumption. Take care of your cooling system and use only premium replacement and aftermarket semi truck engine cooling products we carry, and your engine will never get overheated.
