Mishimoto 17-19 Chevrolet Duramax 6.6L L5P Blue Silicone Radiator Hose Kit

Your Duramax 6.6L L5P engine in your 2017-2019 Chevrolet Silverado or GMC Sierra 2500/3500 HD works hard, whether you're towing or on the job. The factory rubber and plastic radiator hoses can degrade over time from heat cycles and high mileage, leading to potential leaks. Mishimoto developed this silicone radiator hose kit to offer a more durable solution for your truck.

This kit replaces the stock components with hoses made from five layers of silicone, reinforced with heat-resistant embedded fibers. The factory plastic connectors are swapped out for all-aluminum hose junctions, which handle heat and pressure much better. This well-built construction means these hoses are ready for years of service, even in tough conditions. Mishimoto includes all the necessary stainless-steel clamps and a new O-ring for the lower hose quick-disconnect fitting, ensuring a hassle-free and leak-free installation.
