Description
The Mishimoto MMHOSE-GM-5U Silicone Upper Radiator Hose replaces the aging rubber upper radiator hose on the 1968-1972 Chevrolet Chevelle with a five-layer silicone construction designed to outlast the factory part. Finished in black and backed by the Mishimoto Lifetime Warranty, this Classic Line cooling component ships with two worm-gear clamps so installation stays straightforward.
Rubber hoses are prone to cracking, softening, and collapsing over time, and Mishimoto built this silicone hose to address exactly that. Each hose in Mishimoto’s Cooling lineup is layered from five plies of silicone with heat-resistant embedded fibers, giving it improved heat and pressure tolerance compared to the OEM rubber hose it replaces. It is a specific-fit, performance-grade hose engineered for the exact routing of the applications below, and the included worm-gear clamps mean you don’t need to source separate hardware to complete the swap. Whether the Chevelle sees regular cruise nights or occasional show duty, this silicone upper radiator hose is built to keep coolant flowing reliably.
Vehicle Applications
This hose is engineered as a specific fit for a range of GM platforms centered on the classic Chevelle. It covers the Chevrolet Chevelle across the 300 in 1968, the 300 Deluxe from 1968-1969, the Concours and Nomad from 1968-1972, the Concours Estate and Greenbrier from 1969-1972, the Base trim from 1970-1972, and the Malibu and SS trims from 1971-1972.

Additional coverage includes the 1971-1972 Chevrolet Bel Air, Biscayne, Brookwood, Caprice, and Impala, plus the 1971-1972 GMC Sprint.
