Product Details

Standard Ignition ETB159 is an EGR tube used in the emission control system to route exhaust gases between components as part of the vehicle’s recirculation circuit. The tube measures 24 inches long with a 1.54-inch inner diameter and includes a gasket or seal for the connection. This part cross-references ACDelco 2-40208 for the same application. If you are replacing a worn or leaking EGR tube on a Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, or GMC Sierra 3500 HD, ETB159 provides the specified fitment for those model years.

Common Replacement Reasons

• EGR leak at the tube or sealing surface
• Cracked, corroded, or heat-damaged EGR tubing
• Emission system fault codes related to exhaust gas recirculation flow
• Exhaust odor or soot buildup around the EGR connection
• Failed inspection tied to emission control system condition

Installation Notes

Verify the tube length, inner diameter, and connection points before installation. Inspect mating surfaces for carbon buildup or corrosion, and replace damaged seals or gaskets as needed. Because no mounting bracket is included, confirm the vehicle’s existing bracketry and hardware are serviceable before beginning the repair. Always match the part to the exact vehicle application listed for 2017-2022 Chevrolet Silverado 2500 HD and Silverado 3500 HD, or 2017-2022 GMC Sierra 2500 HD and Sierra 3500 HD.
