Mishimoto diesel upgrade coolant hoses increase reliability

Hard working trucks are put under a lot more load and tougher driving conditions than the ordinary pickups, so engine cooling systems need to be tough.

One way to bullet-proof a Duramax 6.6Lā€™s cooling system is upgrading the hoses with a Mishimoto 6.6L Duramax Silicone Coolant Hose Kit for the perfect combination of performance and durability.

Mishimoto diesel coolant hoses are manufactured with high-grade silicone and five layers of heat-resistant embedded fibers to provide increased pressure and temperature tolerance. 

This hose kit also has billet CNC-machined quick-disconnect ends for a direct factory fitment on stock and modified trucks with absolutely no cutting required.

The Mishimoto 6.6L Duramax Silicone Coolant Hose Kit includes the Mishimoto Lifetime Warranty and is offered in black, blue, or red.
