Description
The Mishimoto MMHOSE-F2D-11OV is a one-piece silicone coolant overflow Y-hose engineered specifically for the 6.7L Powerstroke platform. It replaces the factory hose’s plastic fittings, which are known to crack and leak over time, with a seamless silicone design that removes those common failure points before they can leave you stranded.
Part of Mishimoto’s Cooling lineup, this overflow hose is built from multi-layer silicone that outlasts the factory rubber hose it replaces. An integrated one-way valve keeps coolant flowing where it should, while protective heat sleeves shield the hose from high engine bay temperatures. Because it is a direct-fit, vehicle-specific hose rather than a universal piece, installation restores factory-style routing without cutting or splicing, and the included worm-gear clamps help ensure a consistent, reliable seal at every connection.

This Mishimoto silicone Y-hose is designed for 2011–2014 Ford F-250 Super Duty trucks in FX4, King Ranch, Lariat, XL, and XLT trim, as well as 2011–2014 Ford F-350 Super Duty trucks in King Ranch, Lariat, XL, and XLT trim.
