• Stainless steel construction for corrosion resistance
• Built to help reduce stress fracture risk in high-heat exhaust routing
• 30-inch length with 0.63-inch inside diameter and 0.63-inch outside diameter
• Threaded end 1 design for the specified application
• Package contents: EGR tube
• Part number: 598-148

Detailed Description

This EGR line is made for vehicles that need a replacement exhaust gas recirculation tube with the same basic design and connection style as the original equipment part. It is a fit for 2002 Ford Explorer, 2003 Ford Explorer built to 2/03/03, 2002 Mercury Mountaineer, and 2003 Mercury Mountaineer built to 2/03/03. The stainless steel construction helps the tube stand up to exhaust heat, corrosion, and carbon-related restriction in the EGR path. If you are replacing a damaged or restricted EGR tube on an Explorer or Mountaineer, Dorman 598-148 provides a direct-fit service part for the listed applications. This part cross-references OE number 1L2Z9D477CA for the same application.

What It Helps Address

• EGR tube cracking from heat cycling and vibration
• Corrosion in the exhaust gas recirculation line
• Carbon buildup that can restrict EGR flow
• Check engine light concerns related to EGR tube failure
• Exhaust leaks at the EGR tube connection points

Installation Notes and Tips

Verify the vehicle build date before ordering, since the 2003 Ford Explorer and 2003 Mercury Mountaineer coverage applies only to units built to 2/03/03. Inspect the mating surfaces, threaded connection, and nearby EGR components before installation. Clean carbon deposits from the mounting area and confirm the tube routing matches the original layout on the vehicle. Professional installation is recommended for proper sealing and fitment.

Quality Assurance

Dorman designs this EGR tube as a direct replacement for the original equipment part, with materials and construction selected to match the demands of the exhaust gas recirculation system. Part number 598-148 is built for the listed Ford Explorer and Mercury Mountaineer applications.
