Engineered specifically for 2011 through 2016 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.7L Powerstroke turbo diesel engine, this genuine Ford OEM Lower Radiator Coolant Hose (BC3Z-8286-B / Motorcraft KM-5041) connects directly to the lower outlet port of the primary radiator. On the dual-radiator 6.7L Super Duty platform, the primary lower radiator hose assembly is split into two sections: the engine/water pump side (BC3Z-8286-E) and this dedicated radiator-side lower section (BC3Z-8286-B).

Subjected to thousands of hours of high coolant velocities, suction pressure changes, and road vibration, the original rubber hose softens, while its composite quick-disconnect coupler collar becomes brittle and prone to micro-cracking. Replacing a worn or weeping lower hose with genuine Ford part number BC3Z-8286-B restores factory burst resistance and leak-free sealing with a pre-installed OE quick-connect coupler that locks securely onto the primary radiator outlet stub.

Key Features & Benefits

• Genuine Ford Motorcraft Quality: Manufactured to stringent OE vehicle engineering standards for exact fitment, zero chafing, and dependable sealing.
• Pre-Assembled Quick-Connect Coupling: Features the factory-style quick-disconnect connector with internal O-ring and spring clip for a fast, leak-free radiator seal.
• Resists Suction Collapse & Ballooning: Multi-ply fiber-reinforced synthetic EPDM rubber maintains its rigid internal diameter under demanding water pump draw.
• Electro-Chemical Degradation (ECD) Resistant: Specially compounded to resist electrochemical breakdown and internal pitting caused by high-flow diesel coolant contact.
• Precision Factory Molded Contour: Pre-bent to clear lower fan shroud framing, steering links, and chassis crossmembers without rubbing or binding.
