Description
The Mishimoto MMHOSE-GM-25U is a black silicone upper radiator hose engineered as a direct fit for the 1973-1986 Chevrolet/GMC C/K Truck equipped with the 250 4.1L or 292 4.8L engine. Built to replace the factory rubber hose that grows brittle and cracks with age, this Classic Line component is constructed from five layers of silicone reinforced with heat-resistant embedded fibers for a noticeable step up in durability.
As part of Mishimoto’s Cooling lineup, this silicone upper radiator hose is rated Performance grade and carries a maximum temperature rating of 330 degrees, giving your C/K Truck’s cooling system added heat and pressure tolerance compared to aging rubber. It’s a specific-fit hose designed to bolt in with no modification, and it comes packaged with two worm-gear clamps so installation is straightforward. Whether the truck is a weekend cruiser or a show vehicle, upgrading to a Mishimoto silicone hose helps protect against the degradation that eventually leads to cooling system failure. The hose is available in black and, like every Mishimoto Classic Line part, is backed by the Mishimoto Lifetime Warranty.
