The Mishimoto Silicone Coolant Hose Kit replaces the factory rubber coolant hoses on the 6.6L Duramax with five-layer silicone hoses reinforced with heat-resistant embedded fibers for added durability and burst resistance. A 6061 aluminum CNC-machined coupler mates the lower radiator hose to the factory radiator, and T-bolt clamps are included for a secure, leak-free installation. The hoses are finished in red silicone.
