Reseal the EGR valve mounting joint and keep recirculated exhaust gas routed through its intended path with the Standard Ignition Exhaust Gas Recirculation (EGR) Valve Gasket VG124. It fits as a direct-fit replacement for the 2004-2005 Chevrolet Silverado 2500 HD, the 2005 Chevrolet Silverado 3500, the 2004-2005 GMC Sierra 2500 HD, and the 2004-2005 GMC Sierra 3500.
- Sealing job: forms the seal at the joint between the EGR valve and its mating surface, helping contain the recirculated exhaust gas the EGR system meters back toward the intake.
- Direct fit: a direct-fit replacement for the listed applications, installing where the EGR valve mounts.
- Service part: a common replace-on-service item whenever the EGR valve is removed, since old gaskets are typically not reusable.
The EGR system recirculates a metered amount of exhaust gas to lower combustion temperatures and help reduce NOx. If a leaking or crushed gasket at this joint is the cause of an exhaust leak, rough idle, or a stored EGR-related code, this gasket replaces the failed seal. Diagnose the underlying cause before replacing, as those symptoms can have other sources.
Manufacturer part number: VG124.
Frequently Asked Questions
What does this gasket do?
It seals the joint between the EGR valve and its mounting surface, helping contain the recirculated exhaust gas as it passes through the EGR system.
Which vehicles does the VG124 fit?
The 2004-2005 Chevrolet Silverado 2500 HD, 2005 Chevrolet Silverado 3500, 2004-2005 GMC Sierra 2500 HD, and 2004-2005 GMC Sierra 3500. See the Buyer's Guide tab to confirm your vehicle.
What are signs this gasket may need replacing?
An exhaust leak or hissing at the EGR valve, rough idle, or a stored EGR-related code can be signs the gasket is leaking. Diagnose the cause before replacing.
Can I reuse the old gasket?
EGR valve gaskets are generally single-use. Install a new gasket whenever the EGR valve is removed rather than reusing the original.
Is the EGR valve included?
No. This listing is for the EGR valve gasket only; the EGR valve and any fasteners are not included.
