This Mishimoto one-piece silicone coolant overflow Y‑hose is a direct-fit replacement for 2011–2014 Ford 6.7L Powerstroke trucks, eliminating brittle plastic fittings that commonly crack. Constructed from multi-layer silicone, the hose removes multiple potential leak points and includes an integrated one‑way valve, protective heat sleeves and new worm-gear clamps for a reliable seal. It’s intended to improve durability over the factory rubber components.
