Walker 570-5100 Exhaust Gas Recirculation (EGR) Valve

Walker 570-5100 EGR Valve Overview

Walker 570-5100 is an OE replacement exhaust gas recirculation valve built to restore 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 Ranger, Ford Crown Victoria, Ford Taurus, Mercury Sable, Mazda B2300, Mazda B2500, and related applications listed below.

Key Features

• OE-style EGR valve for factory-fit replacement
• Electronically controlled design with 1 female circular connector
• 1 vacuum port and 2 mounting holes for direct installation layout
• Built from heat- and corrosion-resistant materials for under-hood exposure
• Engineered to match OE flow rate, actuation timing, electrical connectivity, and valve position control
• Walker part number 570-5100 for emissions service and repair lookup

Detailed Description

Walker 570-5100 is an exhaust gas recirculation valve that helps regulate the amount of exhaust gas routed into the intake stream. By lowering peak combustion temperatures, the valve supports reduced nitrogen oxide emissions and stable engine operation. This OE replacement is built for exact mounting and connector alignment, making it a direct-service option for vehicles such as Ford Ranger, Ford Crown Victoria, and Mazda B2500 applications. The part number 570-5100 is also useful when cross-checking service records or ordering by reference.

This part cross-references Standard Ignition EGV471 and EGV535 for the same application.

What It Helps Address

• Emissions-related fault codes tied to EGR flow or valve position
• Rough idle caused by incorrect exhaust gas recirculation
• Driveability concerns from restricted or inconsistent EGR operation
• Failed emissions inspection results related to NOx control
• Service replacement for worn or carbon-contaminated EGR valves
