This part cross-references Dorman - HELP 83845 and Gates 18993 for the same application.

What It Helps Address

• EGR cooler leakage or internal failure
• Excessive exhaust gas temperatures in the recirculation circuit
• NOx-related emissions faults
• Check engine lights tied to EGR system performance
• Rough running or drivability issues linked to EGR cooling problems

Installation Notes and Tips
