The Mishimoto MMHOSE-DMAX-17 Silicone Radiator Hose Kit are a superior replacement for the rubber radiator hoses in your 2017-2019 GM 6.6L Duramax L5P. The stock radiator hoses on the Duramax L5P are manufactures from a mixture of molded rubber and plastic couplers. Thousands of heat cycles, hours of idle time, and countless high-stress miles will cause the materials in your truck to deteriorate, harden, and potentially leak. That's why Mishimoto created a new silicone coolant hose kit for the 2017-2019 6.6L L5P Duramax.

The Mishimoto MMHOSE-DMAX-17 Silicone Radiator Hose Kit features all-aluminum hose junctions and five-layer silicone hoses with heat-resistant embedded fibers. This combination produces considerably more durable coolant channels that will last for years even in the most extreme conditions. This kit also includes a complete pair of stainless-steel clamps as well as a replacement O-ring for your bottom hose quick-disconnect fitting, ensuring a hassle-free installation. The Mishimoto Silicone Coolant Hose Kit comes with a Lifetime Warranty and is available in Black, Blue, or Red.
