Mishimoto Silicone Coolant Overflow Y-Hose for 2011-2014 Ford F-250/F-350 Super Duty (6.7L) MMHOSE-F2D-11OV

Fits 2011-2014 Ford F-250 and F-350 Super Duty (6.7L).

The 6.7L Powerstroke is a workhorse, but its factory cooling system relies on plastic fittings in the coolant overflow hose that are notorious for cracking and leaking under thermal stress. Mishimoto addresses this vulnerability with a direct-fit, one-piece silicone Y-hose designed to eliminate those weak points. By replacing the brittle plastic and multi-piece rubber assembly with seamless silicone, this hose removes eight potential leak points to ensure your truck stays on the job without overheating.

This hose is engineered for the rigors of heavy-duty diesel use, featuring multi-layer silicone construction and integrated heat sleeves to withstand high engine bay temperatures. A built-in one-way valve is included to maintain the factory-specified coolant flow and pressure. The kit comes complete with stainless steel worm-gear clamps for a secure, leak-free installation.
