What It Helps Address

• EGR valve-to-intake manifold exhaust leakage
• Unstable sealing at the EGR mounting surface
• Loss of exhaust gas recirculation flow integrity
• Service replacement for worn or damaged gasket surfaces
• Fitment issues on offset bolt pattern EGR assemblies

Installation Notes and Tips

Confirm the vehicle year, make, model, and EGR configuration before ordering. This gasket is for the EGR valve to intake manifold location and is specified for steel construction with no additional package contents. Clean both mating surfaces thoroughly, inspect the flange for warpage or carbon buildup, and follow the factory torque sequence during reassembly. For GM truck service, match the offset bolt pattern and cooler-related notes to the original part.

Quality Assurance

Mahle gaskets are used by OEMs and technicians worldwide for sealing applications that require consistent fit and reliable surface contact. F31911 follows that OE-oriented approach for emission control service on the listed Chevrolet and GMC trucks.
