Description
The Mishimoto MMHOSE-F2D-99RRBK is a silicone coolant hose reroute kit purpose-built to solve one of the most annoying maintenance headaches on the Ford 7.3L Powerstroke: Ford originally routed the upper radiator hose through the serpentine belt, so every belt change meant draining, refilling, and bleeding the entire cooling system. This Mishimoto kit shifts that upper coolant hose behind the belt, so the belt can finally be swapped on its own.
Beyond the clever reroute design, this Mishimoto Cooling product is built from a combination of high-grade silicone reinforced with four layers of heat-resistant embedded fibers, giving it durability meant to outlast the stock rubber hose it replaces. Because the kit is a specific-fit, performance-grade part rather than a universal hose, it drops into the factory routing with the correct shape and clamps needed for a clean install. The result is a coolant hose reroute kit that turns a multi-hour, messy cooling-system service into a straightforward belt swap, while also giving you a fresh upper hose as part of the process.
Vehicle Applications
This Mishimoto coolant hose reroute kit is a specific fit for the Ford 7.3L Powerstroke Super Duty lineup: the Ford F-250 Super Duty, F-350 Super Duty, and F-450 Super Duty from 1999 through 2001, the Ford F-550 Super Duty from 1999 through 2002, and the Ford Excursion for the 2000 model year. Because Ford changed the water pump connection partway through this production run, it’s important to confirm your truck’s exact build date—found on the door jamb sticker—rather than relying on model year alone; trucks built before approximately 4/26/2001 use the earlier straight-fitting connection covered by this kit, while trucks built on or after that date use a curved water pump connection and require a different kit.
