Product Description

The Mishimoto MMHOSE-F2D-17OV Silicone Coolant Overflow Hose is a direct-fit upgrade for 2017-2019 Ford Super Duty trucks equipped with the 6.7L Powerstroke diesel engine. The OEM coolant overflow hose assembly often uses brittle plastic fittings that are prone to cracking and leaking under heat and heavy duty use. This one-piece silicone hose replaces multiple failure points with a seamless design that improves coolant system durability and reliability. 

Constructed from rugged multi-layer silicone with integrated heat protective sleeves, the MMHOSE-F2D-17OV also features a built-in one-way valve to maintain proper coolant flow and includes high-quality worm-gear clamps for a secure, leak-resistant installation. Backed by Mishimoto's Lifetime Warranty, this hose is ideal for owners looking to enhance the longevity and performance of the Powerstroke cooling system under daily driving, towing, and heavy load conditions.
