Product Details

This Dorman EGR cooler is engineered as an OE-style replacement for vehicles that use the original cooler design prone to restriction from soot buildup. By changing the internal flow path to spiral tubes, part number 904-132 supports more efficient exhaust gas cooling while addressing a common failure point in the factory configuration. It is a direct-fit emission control component for 2007-2010 Chevrolet Silverado 2500 HD, 2007-2010 Chevrolet Silverado 3500 HD, 2007-2010 GMC Sierra 2500 HD, and 2007-2010 GMC Sierra 3500 HD applications. This part cross-references Standard Ignition ECK2 for the same application.

What It Helps Address

• EGR cooler clogging from soot and carbon buildup
• Reduced exhaust gas cooling performance caused by a restricted cooler
• Check engine lights related to EGR system flow or efficiency faults
• Rough running conditions tied to EGR system restriction
• Emission control issues on Silverado HD and Sierra HD diesel trucks
