Description
The Mishimoto MMHOSE-F250D-03BK is a black silicone coolant hose kit engineered specifically for the 6.0L Powerstroke, a platform well known among owners for cooling system weak points at the factory rubber hoses. Built from high-grade silicone reinforced with four layers of heat-resistant embedded fibers, this kit is designed to take the place of the OE hoses before they degrade and fail on the road.
Cooling system reliability on the 6.0L Powerstroke depends heavily on hoses that can handle sustained heat and pressure, and Mishimoto’s silicone coolant hose kit was developed to address exactly that. The four-ply silicone construction offers increased pressure and temperature tolerance compared to the factory rubber components, giving these hoses the durability to endure years of use in a demanding diesel cooling system. As a direct-fit, performance-grade replacement, this kit is a straightforward upgrade for anyone looking to get ahead of a common failure point rather than wait for a hose to let go.

This coolant hose kit is a specific fit for the 2003–2004 Ford F-250 Super Duty in Lariat, XL, and XLT trims, along with the 2004 F-250 Super Duty King Ranch and Harley-Davidson Edition.
