Mishimoto Silicone Coolant Hose Kit for 2001-2005 6.6L Duramax

Mishimoto silicone coolant hose kit (MMHOSE-CHV-01DBK) for 2001-2005 Chevrolet/GMC 6.6L Duramax trucks. Black, 330°F rated silicone with included T-bolt clamps.

Description

The Mishimoto MMHOSE-CHV-01DBK is a silicone coolant hose kit engineered specifically for the 2001-2005 6.6L Duramax, built to replace aging factory rubber hoses with a four-ply silicone construction rated to withstand up to 330°F. Finished in black and backed by the Mishimoto Lifetime Warranty, this kit is designed to bolt in with flawless factory fitment while raising the ceiling on heat and pressure tolerance under the hood.

A cooling system is only as strong as its weakest link, and factory rubber hoses are often the first component to crack, swell, or fail under sustained heat. This Mishimoto cooling hose kit replaces those factory hoses with a performance-grade silicone hose built from four layers of heat-resistant fibers bonded to high-grade silicone, giving the Duramax cooling system added durability and increased pressure tolerance. Because it is engineered as a direct, specific-fit replacement rather than a universal hose, installation keeps factory routing intact, and the kit ships with the stainless steel T-bolt clamps needed to complete the job.
