Description
The Mishimoto Silicone Upper Radiator Hose, part number MMHOSE-GM-3U, is a direct-fit replacement engineered specifically for the 1965-1967 Chevrolet Chevelle equipped with a 283 4.6L or 327 5.4L engine. Built from five layers of silicone reinforced with heat-resistant embedded fibers, this Classic Line hose is designed to replace the factory rubber upper radiator hose that hardens and cracks with age, giving your Chevelle a cooling system component rated to withstand up to 330°F.
Where stock rubber hoses degrade under sustained heat and pressure cycles, this Mishimoto silicone hose is built to hold up whether your Chevelle sees daily driving duty or weekend cruise nights. The five-layer silicone construction improves both heat and pressure tolerance compared to the aging rubber hose it replaces, and Mishimoto includes two worm-gear clamps so the upgrade installs as easily as it performs. As part of Mishimoto’s Cooling lineup, this hose is finished in black and backed by the Mishimoto Lifetime Warranty, so Chevelle owners can trust it as a long-term cooling system upgrade rather than a stopgap fix.
