Mishimoto 11-14 Ford 6.7L Powerstroke Coolant Overflow Hose

If you're working on your 2011-2014 Ford F-250 Super Duty with the 6.7L Powerstroke engine, you know the factory coolant overflow hose can be a weak spot. Those plastic fittings are prone to cracking over time, which can lead to coolant leaks and potentially cause your engine to overheat. This Mishimoto Y-hose is designed to replace those failure points with a more robust, one-piece silicone design.

This hose is built from multi-layer silicone, which is known to last longer than the stock rubber and plastic components. By eliminating the factory's multiple plastic connections, this one-piece design removes eight potential leak points. It also features an integrated one-way valve to help keep coolant flowing correctly, and includes heat sleeves to protect it from the high temperatures found in the engine bay. New worm-gear clamps are included to ensure a solid seal when you install it.

This is a direct-fit replacement, meaning it’s made to install without needing any modifications. It's a well-built upgrade that addresses a common issue on these Powerstroke trucks, helping to keep your cooling system reliable.
