Specifications

The EGR079 EGR Cooler is built for Mercedes/Detroit Diesel MBE4000 12.8L engines used in 2007–2010 heavy-duty trucks. The EGR cooler lowers exhaust-gas temperature before it re-enters the intake, reducing NOx emissions and controlling combustion heat. When a cooler fails, trucks may lose coolant, spike exhaust temps, or trigger engine derates. This replacement cooler matches OEM fitment, helping restore proper EGR flow, stable operating temperatures, and dependable drivability. Ideal for fleets and shops performing emissions repairs or preventive cooling-system service.
