Description
The Mishimoto MMHOSE-F2D-15OV is a one-piece silicone Y-hose engineered specifically to replace the factory coolant overflow hose on the 6.7L Powerstroke, a component notorious for plastic fittings that crack and leak over time. Built as a seamless silicone unit rather than a multi-piece plastic assembly, this hose removes the weak points that lead to coolant loss, overheating, and unplanned downtime.
Cooling system reliability starts with hardware that can handle sustained heat, and this Mishimoto overflow hose is built from multi-layer silicone designed to outlast the factory rubber hose it replaces. A one-piece design eliminates eight potential leak points found in the stock setup, while a built-in one-way valve keeps coolant flowing in the correct direction. Protective heat sleeves shield the hose from high engine bay temperatures, and the included worm-gear clamps deliver a consistent, reliable seal at every connection. Backed by the Mishimoto Lifetime Warranty, this hose is a straightforward upgrade for owners looking to get ahead of a common Powerstroke cooling system failure point.
Vehicle Applications
This hose is a direct-fit, specific-application part designed for 2015-2016 Ford F-250, F-350, F-450, and F-550 trucks equipped with the 6.7L Powerstroke diesel engine, matching the factory routing so installation follows the same path as the original plastic overflow hose.
