You rely on your Duramax to get where you need to go, whether hauling the family fifth wheel or driving out to the job site.
The factory radiator hoses for the Duramax L5P are constructed from a mixture of molded rubber and plastic.
As your truck endures countless high-stress miles, hours of idle time, and thousands of heat cycles, those materials will begin to degrade, harden, and potentially develop leaks.
That's why this replacement silicone coolant hose kit has been designed by Mishimoto 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 needed 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.
