Description
The Mishimoto MMHOSE-F46-98BK is a black silicone radiator hose kit built specifically for the 1998-2003 Ford F-150 4.6L V8, giving you a direct replacement for the factory upper and lower radiator hoses before age-related rubber degradation turns into a coolant puddle in your driveway. Molded from high-grade 4-ply silicone with heat-resistant embedded fibers, this Performance-grade, specific-fit kit is rated to a maximum temperature of 330°F and arrives with everything needed to get it installed.
Mishimoto engineered this Cooling system hose kit to replace aging rubber hoses that are prone to cracking, swelling, and leaking over time. Because the hoses are molded from silicone rather than standard rubber, they’re built to resist the heat and pressure cycles that break down factory hoses, helping keep coolant contained and your F-150’s cooling system running the way it should. The kit is offered in black, blue, or red, with this listing covering the black version, and every Mishimoto cooler and hose kit is backed by the Mishimoto Lifetime Warranty.
