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

This Mishimoto silicone hose kit is a direct-fit upgrade for 1991-1993 Dodge applications covering D250, D350, W250, W350. It replaces the weak points of the stock part with stronger materials and better flow or cooling so heat, boost and abuse stay under control on street and track duty. AutoTalent lists verified US-market fitment in the table below.

Why upgrade

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. Mishimoto engineers these kits around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.
