Delphi EG10031 EGR Valve

Delphi EG10031 EGR Valve Overview

The Delphi EG10031 is an electronic exhaust gas recirculation valve built for precise emissions control and OE-style fitment. It uses a 5-terminal blade connection with a single female oval connector, and it includes a gasket and exhaust port for a cleaner replacement on service jobs.

Backed by Delphi’s OE heritage and decades of supplier experience, this EGR valve is built with the application knowledge expected in a direct-fit emission control part. It is a practical replacement for 1995 Chevrolet Astro, Blazer, and S10, plus 1995 GMC Jimmy, Safari, and Sonoma, with additional 1994 optional applications.

Key Features

• Electronic EGR valve design for controlled exhaust gas recirculation
• Positive backpressure configuration
• 5-terminal blade connection with female oval connector
• Gasket included for installation
• Exhaust port included
• OE-focused engineering from Delphi
• Part number: EG10031

Detailed Product Description

Delphi EG10031 is an exhaust gas recirculation valve for emission control systems that require electronic operation and positive backpressure calibration. It is built for direct replacement use on 1995 Chevrolet Astro, 1995 Chevrolet Blazer, 1995 Chevrolet S10, 1995 GMC Jimmy, 1995 GMC Safari, and 1995 GMC Sonoma, with 1994 Chevrolet S10, 1994 Chevrolet S10 Blazer, 1994 GMC Jimmy, 1994 GMC Sonoma, and 1994 Oldsmobile Bravada listed as optional fitments. This part cross-references Standard Ignition EGV515 for the same application.

Delphi draws on OE experience and supplier knowledge developed with major automakers, and that background is reflected in the design and application coverage of the EG10031. If you are replacing a worn EGR valve on a 1995 Chevrolet S10 or a 1995 GMC Sonoma, this part number provides a focused match for the original emission-control function.

What This Part Helps Address

• Rough idle caused by a sticking EGR valve
• 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 or backpressure-related EGR system malfunction

Installation Notes and Tips

Verify the connector style, terminal count, and backpressure configuration before installation. The EG10031 uses a female oval connector with five male blade terminals, so matching the electrical connection is important for proper operation. The included gasket should be replaced during service, and the exhaust port should be inspected for carbon buildup or sealing damage before the new valve is installed.

For fitment confirmation, compare the vehicle year, make, model, and EGR system configuration against the listed applications for 1995 Chevrolet Astro, Blazer, and S10, as well as 1995 GMC Jimmy, Safari, and Sonoma.

Quality Assurance

Delphi builds this replacement EGR valve with OE heritage and application knowledge developed through long-term supplier experience with leading automakers. The EG10031 is engineered to support consistent emission-control performance in the listed applications.
