Standard Ignition EGV629 EGR Valve

Exhaust Gas Recirculation Valve for GM Trucks and Vans

Standard Ignition EGV629 is a mechanical EGR valve built for direct-fit replacement on select Chevrolet and GMC applications. It uses stainless steel valve components for durability and a polyester-reinforced silicone diaphragm that resists thermal aging in high-temperature exhaust environments.

Compatible With 1987-1995 Chevrolet and GMC platforms including C1500, Astro, Safari, R10, R20, V10, R1500, and V1500 applications, this EGR valve is built for straightforward service on emission control systems. The Standard Ignition EGV629 also includes a reinforced gasket for complete replacement and a bolt-mount design with two bolt holes and one hose connector.

Key Features

Detailed Description

The Standard Ignition EGV629 exhaust gas recirculation valve regulates exhaust flow back into the intake stream to support proper emission control operation. Its mechanical construction and heat-resistant diaphragm are suited for older GM truck and van platforms where reliable EGR function is critical to drivability and emissions performance. This part number is a practical replacement choice for Chevrolet C1500 and GMC C1500 models, along with Chevrolet Astro and GMC Safari applications across the listed years.

This part cross-references Standard Ignition EGR125D and EGR126 for the same application.

What It Can Help Address

• Rough idle related to EGR valve sticking
• Check engine light caused by EGR flow faults
• Emissions test failures tied to EGR malfunction
• Driveability issues from improper exhaust gas recirculation
• Vacuum or sealing concerns at the EGR mounting point

Installation Notes and Tips

Verify the mounting style, bolt-hole count, and hose connection before installation. Clean the mounting surface thoroughly and inspect the EGR passage for carbon buildup before fitting the new valve and reinforced gasket. Confirm the vehicle application against the listed Chevrolet and GMC fitment for the correct year and model match.

Quality Assurance

Standard Ignition uses stainless steel valve components and a reinforced silicone diaphragm to support durability in high-heat exhaust service. The included gasket supports a complete replacement at the mounting point.
