When you think of changing your serpentine belt, do you also think of spending hours draining, refilling, and bleeding your cooling system? If you do, I'm guessing you own a 1999-2001 Ford 7.3L Powerstroke. For optimal coolant flow Ford, snaked the upper radiator hose of the 7.3L through the serpentine belt, making it impossible to change the belt without draining and refilling the cooling system. Luckily, Mishimoto has a solution to make draining your cooling system to change the serpentine belt a thing of the past.--Our 1999-2001 Ford 7.3L Powerstroke coolant hose reroute kit shifts the path of the upper coolant hose behind the serpentine belt, allowing you to replace the belt without draining the coolant. This kit includes the upper reroute hose, silicone replacement lower hose, and hose clamps for a complete refresh of your radiator hoses. These Powerstroke coolant hoses are manufactured from a combination of high-grade silicone and four layers of heat-resistant embedded fibers to provide the ultimate in durability and performance. The Mishimoto 7.3L Powerstroke silicone coolant hose reroute kit, like all our Powerstroke performance parts, includes our signature Lifetime Warranty.
