Detailed Description

This Dorman exhaust gas recirculation line is built as a direct replacement for the original equipment EGR tube used on select Ford F-250 Super Duty, F-350 Super Duty, and Excursion models. Part number 598-144 matches the original tube’s basic design and connection style, helping restore proper exhaust gas recirculation routing in diesel emission control systems. The stainless steel construction is selected for durability in high-temperature exhaust environments where corrosion, cracking, and soot buildup can affect performance.

This part cross-references Standard Ignition ETB73 for the same application.

Common Issues This Part May Address

• Cracked or stress-fractured EGR tube
• Corrosion at the tube body or connection points
• Restricted exhaust gas recirculation flow from carbon buildup
• Exhaust leaks caused by a damaged recirculation line
• Emission system faults related to EGR tube failure

Installation Notes and Tips

Verify vehicle build date before ordering, especially for 2005 Ford F-250 Super Duty and 2005 Ford F-350 Super Duty models listed from 11/30/04. Confirm the existing tube routing, connector style, and dimensions against the original part before installation. Inspect adjoining EGR components and sealing surfaces for wear, soot accumulation, or damage that could affect the repair.

Quality Assurance

Dorman designs this EGR tube as a direct OE replacement with the same core features and components as the original tube. The stainless steel construction supports long-term service in demanding exhaust gas recirculation applications.
