Mishimoto Silicone Coolant Overflow Hose for 2020-2026 Ford F-250/F-350 (6.7L)

Fits 2020-2026 Ford F-250 and F-350 Super Duty (6.7L).

The Ford 6.7L Powerstroke is designed for heavy-duty performance, yet its factory cooling system relies on plastic overflow hose fittings that are notorious for becoming brittle, cracking, and leaking over time. These failures often lead to overheating and costly repairs. The Mishimoto silicone coolant overflow hose solves this vulnerability by replacing the multi-piece factory assembly with a robust, one-piece silicone Y-hose.

This hose is engineered with a seamless design that eliminates six potential leak points found in the OEM part. Constructed from multi-layer silicone, it offers superior durability compared to factory rubber and features protective heat sleeves to withstand high engine bay temperatures. A built-in one-way valve ensures proper coolant flow is maintained, while the included worm-gear clamps provide a secure, long-lasting seal.
