Silicone Coolant Hose Kit

This upgraded line is constructed from premium materials including a robust PTFE hose, a multi-layer high-temperature silicone coolant line, and precisely CNC-machined aluminum fittings. These components work together to offer significantly improved durability, enhanced leak prevention, and long-term reliability over stock units, making it an ideal replacement for worn or failing OEM lines. This feed line addresses a common failure point in the factory cooling system. OEM coolant feed lines are susceptible to leaks caused by constant vibration and thermal expansion cycles. Spelab's design incorporates features like CNC aluminum fittings with a dual-thread design to ensure a secure, leak-free connection, and a protective sleeve to mitigate wear from vibration in high-stress turbo areas. The detachable hose-to-fitting connection also adds serviceability, allowing for easier replacement or maintenance if needed. However, due to confined spaces, tightening the turbo-side fitting may present a challenge. **Important Fitment Note:** This Turbo Coolant Feed Line is specifically designed for the 2011–2014 Ford F-250 and F-350 models equipped with the 6.7L Powerstroke engine. It is compatible only with OEM part number BC3Z-9U469-A and is NOT compatible with trucks using OEM part number FC3Z-9U469-B.
