Description
The Mishimoto MMHOSE-F2D-20OV is a one-piece silicone coolant overflow Y-hose engineered specifically for the 6.7L Powerstroke, built to replace the factory hose’s plastic fittings that are prone to cracking and leaking over time. Where the OEM design relies on brittle connections, this direct-fit silicone hose is molded as a single seamless piece with an integrated one-way valve to keep coolant flowing correctly.
As part of Mishimoto’s Cooling lineup, this overflow hose is engineered to eliminate the recurring failure points found on stock 6.7L Powerstroke cooling systems. Multi-layer silicone construction is designed to outlast the factory rubber hose, while protective heat sleeves shield the hose from high engine bay temperatures that can accelerate wear. Because it’s a Specific-fit, Performance-grade component rather than a universal hose, it drops in without modification and comes with new worm-gear clamps so installers get a consistent, reliable seal at every connection.
Vehicle Applications
This hose is a direct fit for 2020 and newer Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.7L Powerstroke. Coverage spans the F-250 and F-350 Super Duty XL, XLT, Lariat, King Ranch, and Platinum trims from 2020 through 2026, with the Limited trim covered for 2020 through 2024 on both models. On the F-450 Super Duty, the XL trim is covered from 2020 through 2026, the Limited trim from 2021 through 2024, and the King Ranch, Lariat, Platinum, and XLT trims for the 2026 model year.
