Product Description

The **Mishimoto MMHOSE-F2D-11OV Silicone Overflow Hose** is engineered as a direct-fit upgrade for Ford Super Duty trucks equipped with the 6.7L Powerstroke diesel engine from 2011 through 2014. The factory coolant overflow hose assembly on these trucks often uses plastic fittings and multiple sections that are prone to cracking and leaking under high temperature and heavy-duty operation. This Mishimoto one-piece silicone design eliminates eight major leak points, improving reliability and service life in tough thermal environments. 

Constructed from durable multi-layer silicone with integrated heat protection sleeves and a built-in one-way valve, this overflow hose maintains optimal coolant flow and withstands the rigors of heavy towing, hauling, and extended idling. The kit includes worm-gear clamps for secure installation and is backed by the Mishimoto Lifetime Warranty, making it a robust replacement for the OEM plastic component. This part is ideal for owners looking to enhance the longevity and dependability of their Powerstroke cooling system.
