The Mishimoto upper radiator hose for 1978–1986 GM C/K truck (292) replaces the factory rubber hose with a five-layer silicone construction reinforced with heat-resistant embedded fibers. That construction improves heat and pressure tolerance for classic truck cooling systems. Two worm-gear clamps are included to simplify installation, and the hose is covered by Mishimoto’s Classic Line lifetime warranty.
