Chevrolet Silverado 2500 HD Radiator Coolant Hose - Mishimoto - Silicone, 6.6L Duramax - Blue - 11-16. This Mishimoto silicone coolant hose kit is designed for 6.6L Duramax Silverado/GMC trucks from 2011–2016 and offers a direct-fit replacement for worn or leaking radiator hoses.

The Mishimoto kit is built for durability and consistent cooling performance whether you run a stock truck or a modified setup. Constructed from high-grade silicone with five layers of heat-resistant embedded fibers, the hoses increase resistance to pressure and high temperatures. CNC-machined aluminum couplers and billet quick-disconnect ends provide a factory-style fit without cutting, and included T-bolt clamps simplify installation. Offered in blue to match performance builds, this kit pairs well with Mishimoto aluminum radiators and carries Mishimoto's signature lifetime warranty.
