Ford Powerstroke Radiator Coolant Hose - Mishimoto - Silicone - `17-`19 is a direct-fit one-piece coolant overflow Y-hose designed for the 6.7L Powerstroke (2017–2019). It replaces the factory plastic fittings with durable silicone to reduce common failure points and maintain reliable coolant flow.

Built from multi-layer silicone, this Mishimoto hose resists the heat and age-related degradation that affects factory rubber and plastic overflow lines. The one-piece design removes multiple weak connections found on stock systems, and an integrated one-way valve preserves proper coolant direction. Protective heat sleeves help the hose withstand hot engine-bay conditions, and the kit includes new worm-gear clamps for a consistent seal. Backed by Mishimoto’s warranty, this hose is aimed at owners who want a durable, serviceable solution to prevent leaks and reduce the risk of overheating-related downtime.
