Description
The Mishimoto MMHOSE-GM-18L Silicone Lower Radiator Hose replaces the aging rubber hose in classic GM and specialty vehicles with a five-layer silicone construction built for heat and pressure. Finished in black and backed by the Mishimoto Lifetime Warranty, this Cooling system component is engineered as a direct, specific-fit upgrade rather than a generic universal hose, and it ships with the hardware needed to get it installed.
Rubber hoses degrade over time from constant heat cycling, leading to cracking, swelling, and eventual failure. Mishimoto addresses this with a silicone hose reinforced by heat-resistant embedded fibers across five layers, which improves heat tolerance and pressure tolerance compared to the factory rubber piece. The hose carries a Performance grade rating and a maximum temperature rating of 330°F, giving classic car owners and specialty truck owners a more durable cooling system component whether the vehicle sees regular cruising or occasional show duty. Two worm-gear clamps are included so the hose can be installed without hunting down separate hardware, and the recommended clamp torque is 22 in-lbs (2.5NM), with an operating range of 18-27 in-lbs (2-3NM) and a maximum of 27 in-lbs (3NM).
Vehicle Applications
This Mishimoto silicone lower radiator hose is a specific fit for the 1966-1968 Chevrolet Bel Air, Biscayne, and Caprice, the 1966-1967 Chevrolet Impala, and the 1967 Chevrolet Camaro. It also fits the 1995 Ford F-250 and F-350 in Eddie Bauer, Special, XL, and XLT trims, as well as the 1997 Pontiac Firebird. Mishimoto notes direct fit application for the 1966-1968 Chevrolet Impala equipped with the 383 or 327 engine.
