Description
The Mishimoto Silicone Upper Radiator Hose (MMHOSE-GM-1U) replaces the aging rubber upper radiator hose on your Chevrolet Chevelle with a purpose-built silicone piece engineered for classic muscle car cooling systems. Molded in black and backed by the Mishimoto Lifetime Warranty, this hose is part of Mishimoto’s Classic Line and ships with everything needed to swap out your old rubber hose for good.
Rubber hoses harden, crack, and weep coolant over time, especially in a car that sees regular driving or spirited weekend cruising. Mishimoto addresses that degradation by building this Cooling hose from five layers of silicone with heat-resistant embedded fibers, giving it a level of heat and pressure tolerance that stock rubber simply can’t match. Two worm-gear clamps are included in the box, so installation is straightforward and you’re not left sourcing hardware separately. Whether you’re refreshing a numbers-matching restoration or upgrading a driver-quality Chevelle, this Mishimoto silicone hose is a durable, direct-fit way to modernize an aging cooling system.
