Walker 570-5059 Exhaust Gas Recirculation (EGR) Valve

Walker 570-5059 EGR Valve Overview

Walker 570-5059 is an OE replacement exhaust gas recirculation valve built to restore factory emissions control and drivability. It regulates exhaust gas flow back into the intake manifold to help lower combustion temperatures and reduce NOx output. Compatible With Ford E-150, E-250, E-350 Super Duty, Expedition, Excursion, F-150, F-250 Super Duty, F-350 Super Duty, and Lincoln Navigator applications across the listed model years.

• Built for accurate actuation timing and electrical connectivity
• Exact-fit design with original mounting locations and connector type
• Heat- and corrosion-resistant construction for under-hood exposure
• Connector shape: circle; connector gender: female; connector quantity: 1
• Mounting hole quantity: 2; vacuum port quantity: 1

Detailed Description

Walker Products Part Number 570-5059 is manufactured to meet or exceed OE specifications for flow, actuation, and electrical performance. By metering exhaust gases into the intake stream, the valve helps reduce peak combustion temperatures and supports lower nitrogen oxide emissions while maintaining normal engine operation. This part cross-references Standard Ignition EGV537 for the same application. Walker 570-5059 is a direct-fit emissions component for Ford and Lincoln trucks and SUVs, including Ford F-150, Ford Expedition, Ford Excursion, Ford E-Series vans, and Lincoln Navigator models in the listed years.

Common Issues This Part Addresses

• Check engine light related to EGR valve performance
• Rough idle caused by improper exhaust gas recirculation
• Emissions test failure tied to EGR system faults
• Reduced drivability from incorrect valve opening or closing
• Loss of factory emissions control on Ford and Lincoln applications

Installation Notes and Tips

Verify connector shape, mounting points, and vacuum port layout before installation. Confirm the stamped part number on the original valve when servicing Ford E-150 Econoline, E-250 Econoline, E-350 Econoline, and related Lincoln Navigator applications that list stamped #XL3E9D475CA. Inspect the EGR passages, gasket surfaces, and related sensors or vacuum lines for carbon buildup or damage before replacing the valve. Use the vehicle’s service information to confirm the correct application by year, make, and model.

Quality Assurance

Walker EGR valves are built as OE replacement emissions components and are engineered to meet factory specifications for fit, flow, and control. The design uses materials selected for heat and corrosion resistance to handle continuous exhaust exposure in demanding under-hood conditions.
