The first-generation Cummins offered the venerable 6BT engine, a true legend in reliability, simplicity, and power potential. Keeping up on maintenance items is key to retaining that famous reliability. Coolant hoses are an often-overlooked piece of the reliability puzzle which, after 30 years of service, are likely to need some attention. Upgrade from rubber hoses to the Mishimoto Silicone Radiator Hose kit for superior durability, greater resistance to degradation, and improved styling. Mishimoto silicone hoses are constructed from high-grade silicone with embedded heat-resistant fibers. This combination of materials provides superior temperature resistance up to 330?F. This kit includes replacement silicone radiator hoses and a complete set of high-quality stainless-steel worm gear clamps for easy installation. Available in your choice of black, blue, or red silicone, this kit also adds some additional engine bay style. As with all our products, this silicone radiator hose kit includes the Mishimoto Lifetime Warranty.
