  Motorcraft™ Lower Hose, Hose Radiator

• Description:

  This genuine Ford Motorcraft radiator coolant hose is the molded lower radiator hose for Ford vehicles equipped with the 3.5L twin-turbocharged EcoBoost V6 engine, covering roughly the 2010-2019 model span across the multiple car and truck lines that share this engine and cooling configuration. It connects the lower radiator outlet to the engine cooling circuit and carries cooled coolant back toward the engine, handling full system pressure and temperature while resisting the underhood heat and vibration of the turbocharged application. The hose is molded from a Ford-specified reinforced rubber compound to the precise contour and length needed to route cleanly past the turbo plumbing, accessory drive, and chassis without kinking, stretching, or rubbing. Owners look for this hose when the original is leaking at an end connection or along a bend, weeping coolant, or showing cracks, soft spots, swelling, or heat-hardening, and when a failing lower hose has caused coolant loss, an overheat event, or a low-coolant warning. On boosted 3.5L engines the lower hose sees high thermal cycling and can deteriorate internally before any outside damage is visible. Cataloged as Motorcraft part number KM-5057, it is the correct lower-position molded replacement to restore a sealed cooling circuit. Verify the exact application against your engine and cooling layout, because 3.5L turbo and non-turbo cooling routings differ. When installing, drain and refill with the specified Ford coolant, replace any corroded or weakened clamps, and bleed the cooling system per the factory procedure to purge trapped air. The OEM-molded hose delivers proper fit and lasting sealing that a generic straight hose cannot match.

• Applications: 3.5L W/TURBO.
