Standard Ignition EGV1240 EGR Valve

OE-Style EGR Valve for Heavy-Duty GM Trucks

Standard Ignition EGV1240 is a direct-fit Exhaust Gas Recirculation (EGR) valve for select 2011-2016 Chevrolet Silverado 2500 HD and Silverado 3500 HD, plus 2011-2016 GMC Sierra 2500 HD and Sierra 3500 HD applications. It is built as an OE replacement with electronic control and a flange mount for a factory-style service fit.

Designed to help manage combustion temperatures and NOx output, this EGR valve also addresses a common failure point: carbon buildup. Standard Ignition incorporates extra venting to reduce pressure buildup and limit carbon deposits, helping support longer service life in demanding diesel truck use.

Key Features

• Direct-fit OE replacement EGR valve
• Electronic design with 5 blade terminals
• Female oval connector for factory-style hookup
• Flange mounting style
• Gaskets included
• Engine code LML, VIN code 8
• Standard Ignition EGV1240 for diesel emission control service

Detailed Description

Standard Ignition EGV1240 is engineered for emission control service on compatible Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, and GMC Sierra 3500 HD trucks. This EGR valve helps recirculate exhaust gases to lower combustion chamber temperatures, which supports reduced NOx formation while maintaining drivability and fuel economy. The electronic valve design, female oval connector, and flange mount match the original service configuration for straightforward replacement. If you are replacing a sticking or carbon-loaded EGR valve on a 2011-2016 Silverado 2500 HD or Sierra 3500 HD, this part number is built for that application. This part cross-references ACDelco 12636492 and 12643238 for the same application.

Common Problems This Part Can Address

• Check engine light related to EGR flow or valve performance
• Rough idle caused by a sticking EGR valve
• Excessive carbon buildup in the EGR passage
• Emission control faults on diesel trucks
• Reduced engine efficiency from improper exhaust gas recirculation

Installation Notes and Tips

Verify engine code LML and VIN code 8 before ordering. Confirm the connector shape, terminal count, and flange mounting style match the original unit on the vehicle. Clean mating surfaces before installation and inspect the EGR passages for carbon deposits that could affect the new valve. For fitment, this part is listed for 2011-2016 Chevrolet Silverado 2500 HD, 2011-2016 Chevrolet Silverado 3500 HD, 2011-2016 GMC Sierra 2500 HD, and 2011-2016 GMC Sierra 3500 HD.

Quality Assurance

Standard Ignition premium EGR valves are tested for service life and built to address carbon-related failure concerns through improved venting design. The result is an OE-style replacement intended to restore proper EGR function on the listed GM heavy-duty trucks.
