Description
The Mishimoto MMHOSE-RAM-03DE coolant hose kit is a direct-fit replacement for the upper and lower radiator hoses on 5.9L and 6.7L Cummins-powered Dodge Ram trucks, built to replace cracked or leaking factory hoses with OEM-quality EPDM construction. Backed by the Mishimoto Lifetime Warranty, this specific-fit kit ships complete with worm gear clamps so your cooling system repair is ready to install.
As part of Mishimoto’s Cooling lineup, this coolant hose kit is engineered to restore reliable coolant flow for work trucks and daily drivers alike. Rather than settling for a universal hose that may not seal correctly, this kit is a specific-fit design that matches the factory routing, while the EPDM hose material is chosen to resist long-term degradation from heat and coolant exposure. The performance-grade hoses and included clamps make this a complete, ready-to-install solution for anyone dealing with a failing factory coolant hose on a Cummins-powered Ram.
