Description
The Mishimoto Dodge Ram 5.9L/6.7L Cummins Coolant Hose Kit (MMHOSE-RAM-03DRD) is a direct-fit replacement for the factory rubber coolant hoses on Cummins-powered Ram trucks. Molded from silicone and reinforced with four layers of heat-resistant fibers, this red hose kit is built to handle a maximum temperature rating of 330°F while retaining the factory hose routing.
This Mishimoto coolant hose kit is designed for cooling-system reliability on work trucks and modified pull trucks alike. The silicone construction efficiently reduces heat, increases pressure tolerance, and adds a layer of blowout prevention compared to the factory rubber hoses it replaces. Because the kit is a specific-fit part that retains OE routing, installation is straightforward, and it’s part of Mishimoto’s broader lineup of cooling components engineered to keep diesel cooling systems running dependably.
