If you’re looking to upgrade your F250 parts, look no further! The Mishimoto 1983–1994 Ford 6.9L & 7.3L IDI Diesel Performance Aluminum Radiator is an ideal upgrade for the brittle stock radiator, and provides your truck with enhanced reliability and improved cooling efficiency. Whether your 1990 Ford F250 is a daily driver or you use your 1989 Ford F250 for serious hauling, many people overlook the importance of installing an upgraded radiator in their engine. A stock Ford radiator cannot handle the heat that comes along with having a great deal of horsepower. The Mishimoto Ford 6.9L & 7.3L IDI Diesel 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 performance aluminum radiator also includes a Magnetic Drain Plug, which effectively removes metal fragments circulating in the cooling system. As with all our products, this radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
