Description
The Mishimoto MMHOSE-CHV-06DBL silicone coolant hose kit is a direct-fit cooling system upgrade engineered specifically for 6.6L Duramax-powered Chevrolet and GMC trucks. Molded in blue performance-grade silicone and reinforced with four layers of heat-resistant embedded fibers, this kit pairs with a 6061 aluminum CNC-machined coupler that mates the lower radiator hose directly to the factory radiator for an OEM-style, direct-fit installation.
A leaking coolant hose can lead to serious engine damage if it isn’t caught in time, and Mishimoto built this coolant hose kit to help prevent that outcome. The four-layer silicone and fiber construction increases pressure tolerance and raises the maximum temperature rating to 330°F, so the hose can efficiently reduce heat whether your Duramax is running stock or modified. Mishimoto offers this coolant hose line in black, blue, or red, with this listing covering the blue version, and every kit is backed by the Mishimoto Lifetime Warranty.
