Mishimoto's Duramax coolant hose kits are constructed from a combination of high-grade silicone and four layers of heat-resistant fibers to provide superior durability and increased pressure tolerance. Mishimoto is proud to release a silicone Duramax coolant hose kit specifically for the 2001-2005 6.6L Duramax. The Mishimoto silicone Duramax coolant hose kit is engineered to retain flawless factory fitment and provide years of reliable service. A cooling system is only as strong as its weakest link. Old rubber hoses are prone to failure from years of abuse. Upgrade your Duramax with Mishimoto's Duramax coolant hoses for the ultimate in performance and style. The Mishimoto Duramax coolant hose kit, like all of our Duramax performance parts, comes with the Mishimoto Lifetime Warranty.
