If you're looking to upgrade your GM 3100 Series parts, look no further! The Mishimoto 1955--1959 GM 3100 Series Truck X-Line Performance Aluminum Radiator provides your car with enhanced reliability, improved cooling efficiency, and is an ideal upgrade for the brittle stock radiator. Whether you use your classic for daily driving or take it to the track, many people overlook the importance of installing an upgraded radiator in their engine. A stock radiator cannot handle the heat that comes along with having a great deal of horsepower. The Mishimoto GM 3100 Series Truck X-Line Aluminum 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 GM 3100 Series performance radiator also includes a Magnetic Oil Drain Plug, which effectively removes metal fragments circulating in the cooling system. As with all our products, this GM 3100 Series radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
