The Mishimoto Essentials Bundle for the 1999-2001 Ford 7.3L Powerstroke has you covered. This kit has everything you need to fortify your 7.3L and ensure it runs cool in any situation, including our all-aluminum radiator, silicone radiator hoses, and both our high and low temp thermostats.Our all-aluminum radiator is a direct fit for your 7.3L and features a two-row, 2.2 in-thick core for effective cooling in any driving condition, while the precision TIG-welded aluminum end tanks ensure maximum durability over the stock plastic tanks. For even greater longevity, this kit also includes our silicone radiator hose kit. These hoses feature four layers of silicone with embedded heat-resistant fibers and will outlive your stock rubber hoses, if not your truck. Finally, we've also included both our high and low-temp thermostats to suit your climate and performance needs. Our high-temp thermostat opens 10 degrees later than the stock thermostat for faster warmup, while our low-temp thermostat opens 6 degrees earlier for more efficient cooling.Of course, all of the components in this kit are backed by the Mishimoto Lifetime Warranty, so you'll never have to worry about leaks or poor performance ever again!
