Detailed Description

This Dorman exhaust gas recirculation line is built for vehicles that rely on a properly functioning EGR path to route exhaust gases through the emissions system. Part number 598-204 is formed from stainless steel to help withstand heat, corrosion, and the repeated thermal cycling common in GM truck and SUV exhaust systems. It is a direct replacement for the original tube on applications such as the Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade.

This part cross-references Standard Ignition ETB50 for the same application.
