Mishimoto 2020+ Ford 6.7L Powerstroke Coolant Overflow Hose

This Mishimoto silicone hose kit is a direct-fit upgrade for 2020-2027 Ford applications covering F-250 Super Duty, F-350 Super Duty. 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 6.7L Powerstroke is a powerhouse built for serious work, but its factory coolant overflow hose uses plastic fittings that are known to crack and leak over time. Left unchecked, these leaks can lead to overheating and unexpected downtime. Upgrade your cooling system with a Mishimoto one-piece silicone Y-hose designed specifically for your 6. These kits are engineered 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.
