Mishimoto Silicone Coolant Overflow Y-Hose for 2017-2019 Ford F-250/F-350 (6.7L) MMHOSE-F2D-17OV

Fits 2017-2019 Ford F-250 and F-350 Super Duty (6.7L).

The 6.7L Powerstroke is a workhorse, but the factory cooling system relies on plastic overflow hose fittings that are prone to cracking and leaking over time. The Mishimoto MMHOSE-F2D-17OV silicone coolant overflow hose eliminates these vulnerabilities. By replacing the multi-piece factory assembly with a single, seamless silicone Y-hose, you remove six potential leak points and ensure long-term cooling reliability for your Ford Super Duty.

This direct-fit hose is constructed from heavy-duty multi-layer silicone, offering superior heat and pressure resistance compared to factory rubber. It features an integrated one-way valve to maintain precise coolant flow and includes protective heat sleeves to shield the silicone from extreme engine bay temperatures. The kit comes complete with stainless steel worm-gear clamps for a secure, leak-free installation and is backed by the Mishimoto Lifetime Warranty.
