This Mishimoto one-piece silicone coolant overflow Y‑hose is a direct-fit replacement for 2015–2016 Ford 6.7L Powerstroke models, replacing fragile plastic connections with a seamless silicone design. The multi-layer silicone construction outlasts factory rubber, the integrated one-way valve helps maintain coolant flow, and included clamps ensure consistent sealing. The kit targets common failure points in the stock overflow plumbing.
