Whether you’re hauling the family fifth wheel or driving out
Whether you’re hauling the family fifth wheel or driving out to the job site, you rely on your Duramax to get where you need to go. The factory Duramax L5P radiator hoses are constructed from a mixture of molded rubber and plastic. As your truck endures thousands of heat cycles, hours of idle time, and countless high-stress miles, those materials will begin to degrade, harden, and potentially develop leaks. That's why Mishimoto has designed this replacement silicone coolant hose kit for your 2017-2019 6.6L L5P Duramax. This kit features hoses constructed from five layers of silicone with heat-resistant embedded fibers and all-aluminum hose junctions. This combination yields far more robust coolant passages, which will provide years of service in the harshest conditions. This kit also includes a full set of stainless-steel clamps and a replacement O-ring for your lower hose quick-disconnect fitting, providing everything you need for a hassle and leak-free installation. The Mishimoto Silicone Coolant Hose Kit is available in Black, Blue, or Red and includes our signature Mishimoto Lifetime Warranty.
