An ideal upgrade for the brittle stock radiator, the Mishimoto 1978–1986 GM C/K Truck X-Line Performance Aluminum Radiator provides your truck with enhanced reliability and improved cooling efficiency. Whether you use your classic for daily driving or take it to the track, don't overlook the importance of installing an upgraded classic truck radiator in your engine. A stock radiator cannot handle the heat that comes along with having a great deal of horsepower. This GM C/K truck radiator is manufactured using durable aircraft-quality aluminum end tanks, precision TIG-welded to an efficient brazed aluminum core. The inlet and outlets provide precise leak-free connections. This classic car radiator also includes a magnetic oil drain plug, which effectively removes metal fragments circulating in the cooling system. As with all our aluminum radiators, every GM C/K truck radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
