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 Aluminium Radiator provides your truck 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 Aluminium Radiator is manufactured using durable aircraft-quality aluminium end tanks, precision TIG-welded to an efficient brazed aluminium core. The inlet and outlet 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 aluminium radiators, this GM 3100 Series radiator includes the Mishimoto Lifetime Warranty, ensuring superior Products quality and craftsmanship.
