Mishimoto 1991-1993 Dodge 5.9L Cummins Silicone Coolant Hose Kit Black

The 6BT engine in your first-generation Cummins is a legendary piece of machinery, known for its reliability and power. Keeping up with maintenance is key to preserving that reputation, and coolant hoses are a critical, often overlooked, part of that. After 30 years, your original rubber hoses are likely showing their age and could be prone to failure. This Mishimoto silicone radiator hose kit is a smart upgrade, replacing those old rubber lines with a more durable and heat-resistant option.

These hoses are built from high-grade, 4-ply silicone and reinforced with embedded heat-resistant fibers. This construction allows them to handle temperatures up to 330°F, significantly more than standard rubber hoses. The kit comes complete with both the upper and lower radiator hoses, plus a full set of stainless-steel worm gear clamps, making installation straightforward. Beyond their improved performance, these black silicone hoses also give your engine bay a cleaner, more stylish look.
