Okay, lets face it your 6.9L or 7.3L Ford IDI is a classic. We’re talking almost a 30 year old classic. So it would make sense if you needed to replace your brittle stock radiator. The Mishimoto 1983–1994 Ford 6.9L & 7.3L IDI Diesel Performance Aluminum Radiator is an ideal upgrade 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. This radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
