Product Description

The Mishimoto **MMHOSE-F2D-15OV Silicone Coolant Overflow Hose** is a direct-fit cooling system upgrade for 2015-2016 Ford Super Duty trucks equipped with the 6.7L Powerstroke diesel engine. Factory coolant overflow/Y-hose assemblies on these models often use plastic fittings that are prone to cracking and leaking over time - which can lead to coolant loss and overheating concerns. This one-piece seamless silicone hose replaces those weak OEM components with a durable, heat-resistant solution that improves long-term reliability. 

Constructed from multi-layer silicone and featuring an integrated one-way valve to maintain proper coolant routing, the MMHOSE-F2D-15OV also includes protective heat sleeves and worm-gear clamps for a secure installation. This hose is engineered to withstand the harsh engine bay environment of heavy-duty diesel applications, reducing the risk of leaks and failures compared to stock rubber and plastic hoses. Backed by the Mishimoto Lifetime Warranty, it's a dependable upgrade for owners seeking enhanced cooling system performance and durability.
