Mishimoto 11+ Chevrolet Duramax 6.6L Black Silicone Coolant Hose Kit

The five layers of heat-resistant embedded fibers within this silicone coolant hose kit are key to its improved durability. When you're dealing with the heat generated by a 6.6L Duramax engine, especially in demanding conditions or with modifications, having hoses that can handle increased pressure and temperature is critical. A leaking coolant hose can quickly lead to serious engine damage, so upgrading to a well-built silicone kit like this one from Mishimoto is a smart move for keeping your truck on the road.

These hoses are constructed from high-grade silicone, making them a solid option for both stock and modified trucks, no matter the environment. The kit includes CNC-machined 6061 aluminum couplers for the lower radiator hose, which connect directly to the factory radiator without any cutting required, ensuring a direct fit. This attention to detail in the design means installation should be straightforward, especially with the included T-bolt clamps.

This Mishimoto hose kit is designed to work perfectly with their 6.6L Duramax Aluminum Performance Radiator, creating a complete cooling system upgrade that's built to last. It's a well-made component that addresses a common failure point and offers peace of mind for owners of Chevrolet and GMC trucks from 2011 through 2016.
