• Description:

  This genuine Ford JL3Z-8276-B is the engine coolant reservoir hose for the 2018 through 2020 Ford F-150, cataloged by Ford as Reservoir Hose and identified as the lower reservoir hose on the 3.0L, 3.3L, and 5.0L applications. It connects the coolant expansion and degas reservoir into the engine cooling circuit, allowing coolant to flow between the reservoir and the system so the tank can vent air, accept expansion as the engine warms, and feed makeup coolant back as the system cools. Because it is a molded rubber hose that lives in the hot underhood environment, it hardens, cracks, swells, or splits with age and heat cycling, and the connection points can weep. Symptoms that send a buyer looking for this hose include a low coolant warning, coolant loss with no obvious puddle, a sweet coolant smell, seepage or crusty residue around the reservoir hose ends, and in worse cases engine overheating from air drawn into the system through a failed hose. Replacing it with the correct Ford hose restores a sealed cooling circuit and proper coolant recovery. This part is engine keyed, so confirm your truck has the 3.0L, 3.3L, or 5.0L before ordering, as other engines use different reservoir plumbing. Refill and bleed the cooling system with the specified Motorcraft coolant after installation and check for leaks. As a genuine Ford component it matches the factory routing, length, and fitting shape for a direct fit, avoiding the mismatched bends and loose connections common to universal replacement hose.
