Delphi EG10593 Exhaust Gas Recirculation (EGR) Valve

OE-Style EGR Valve for Ford and Lincoln

Delphi EG10593 is an exhaust gas recirculation (EGR) valve built for negative back pressure systems used across a wide range of Ford, Lincoln, and Mercury applications. It is a direct-fit emission control component for restoring proper exhaust gas recirculation function on vehicles such as the Ford F-150, Ford Expedition, and Lincoln Navigator.

Key Features

• Negative back pressure EGR valve design
• Threaded terminal type with 1 round female connector
• 1 vacuum port with 0.196 in. (5 mm) diameter
• 2 mounting holes for OE-style installation
• Gasket included; exhaust port not included
• Built using OE-based design specifications and validation testing
• Delphi part number EG10593

Product Details

Delphi EG10593 is engineered for emission control service where a negative back pressure EGR valve is required. Delphi applies OE heritage, material selection standards, and manufacturing controls developed from more than a century of original-equipment experience. The result is a replacement EGR valve designed around factory-style fit, connector layout, and vacuum-port configuration for service on Ford F-150, Ford Expedition, Ford E-150, and related applications. This part cross-references Standard Ignition EGV464 and EGV537 for the same application. Delphi EG10593 is a practical choice when replacing a worn or sticking EGR valve on compatible Ford and Lincoln trucks, vans, and SUVs.

What It Helps Address

• Rough idle caused by an EGR valve that is sticking open or closed
• Check engine light related to EGR flow or valve performance
• Emissions test failure tied to exhaust gas recirculation faults
• Driveability issues from improper exhaust gas recirculation control
• Vacuum-related EGR operation problems on negative back pressure systems

Installation Notes

Verify negative back pressure EGR system requirements before installation. Confirm the round female connector, threaded terminal style, 1 vacuum port, and 2-bolt mounting pattern match the original part. The gasket is included; mounting hardware is not listed in the package contents. Clean the mounting surface and inspect vacuum lines and electrical connections before installing the new valve. Fits 1997-2003 Ford F-150, N/A; Fits 2000-2004 Ford Expedition, N/A; Fits 1998-2004 Lincoln Navigator, N/A.

Quality Assurance

Delphi uses OE-based design specifications, validation testing, and controlled manufacturing processes to support consistent part quality. EG10593 reflects Delphi’s original-equipment engineering approach for emission control service.
