Radiator Hoses

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.
Complete radiator coolant hose kit designed to maintain proper coolant flow and system pressure. Includes durable, heat-resistant hoses for leak prevention, reliable performance, and a precise, easy installation.

• Replaces stock plastic connectors with aluminum for greater resistance to heat and pressure
• Constructed from five layers of silicone with heat-resistant embedded fibers
• Includes new lower radiator hose O-ring for leak-free install

The 6.7L Powerstroke is a powerhouse built for serious work, but its factory coolant overflow hose uses plastic fittings that are known to crack and leak over time. Left unchecked, these leaks can lead to overheating and unexpected downtime. Upgrade your cooling system with a Mishimoto one-piece silicone Y-hose designed specifically for your 6.7L Powerstroke to eliminate those weak points and keep your truck on the road.–This direct-fit hose replaces those old, brittle plastic connections with a seamless silicone design that removes common failure points. A built-in one-way valve maintains proper coolant flow, and protective heat sleeves help guard the hose against high engine bay temperatures.–Made from multi-layer silicone that outlasts the factory rubber, this hose is built to handle the demands of the Powerstroke platform. Each kit includes new worm-gear clamps for a consistent, reliable seal and is backed by the Mishimoto Lifetime Warranty.
