• Description:

  This genuine Ford EGR by-pass valve controls the routing of exhaust gas within the exhaust gas recirculation system on the 2018-2021 Ford F-150 equipped with the 3.0L Power Stroke diesel engine. The by-pass valve directs exhaust flow through or around the EGR cooler depending on operating conditions, supporting proper emissions control and engine temperature management. Built to original equipment specifications, it is the updated revision of this service part and addresses the durability concern associated with the earlier version, in which the valve shaft could fracture and release a loose thrust washer that risked being drawn into the engine. Owners typically seek this component in connection with the diesel EGR by-pass valve service action, after an EGR-related warning, or when correcting a known shaft failure on the affected trucks. A failed or weakened by-pass valve can disturb exhaust routing, set diagnostic codes, and in the worst case allow internal hardware to break free, so installing the improved revision restores correct and safer operation. As a Ford catalog by-pass valve for the diesel application, it is engineered to fit the listed F-150 model years and withstand the heat and pressure of the EGR circuit. During installation, follow the factory service procedure, inspect the connected EGR cooler and tubes, use any required new fasteners and seals, and clear stored codes afterward. Choosing the original Ford valve helps ensure reliable emissions operation and proper protection for the diesel engine.
