Why is the factory coolant overflow hose prone to leaking?

The factory coolant overflow hose on these trucks uses plastic fittings that can become brittle and crack over time, especially under the high temperatures of the engine bay. This cracking leads to coolant leaks and potential overheating issues.

What makes the Mishimoto hose a better option?

This Mishimoto hose is made from multi-layer silicone, which is more durable and flexible than the factory rubber and plastic components. Its one-piece design eliminates multiple connection points where leaks commonly occur, and it includes heat sleeves for added protection.

Does this hose come with everything needed for installation?

Yes, this kit includes the silicone Y-hose with an integrated one-way valve and protective heat sleeves, along with new worm-gear clamps to ensure a secure and reliable seal during installation.

About this part

Product Details

Your 2020-2025 Ford F-250 Super Duty with the 6.7L Powerstroke engine relies on a robust cooling system, but the factory coolant overflow hose often uses plastic fittings that can become brittle and crack over time. This can lead to coolant leaks, potential overheating, and costly downtime. Mishimoto offers a direct-fit, one-piece silicone Y-hose designed specifically to replace those common failure points.

This updated hose swaps out the weak plastic connections for a seamless, multi-layer silicone construction that's built to last. It features an integrated one-way valve to ensure proper coolant flow and comes with protective heat sleeves to shield it from the high temperatures found in the engine bay. The one-piece design effectively removes six potential leak points found in the factory setup, giving you a more reliable cooling system.

Included with the hose are new worm-gear clamps to create a solid, consistent seal. This Mishimoto hose is a well-built upgrade designed to handle the demands of the Powerstroke platform, keeping your truck running strong.
