Dorman 598-142 EGR Line

Dorman 598-142 EGR Tube for Ford and Lincoln

Dorman 598-142 is a direct replacement exhaust gas recirculation tube built for select Ford, Lincoln, and Mercury applications. It is made from stainless steel and engineered to resist stress fractures, corrosion, and carbon buildup blockage in the EGR passage.

Use this EGR line for a factory-style repair on a 1996-2000 Lincoln Town Car, 1996-1997 Ford Crown Victoria, and 1996-1997 Ford/Mercury Grand Marquis applications. The Dorman 598-142 matches the original tube’s key features and components for a straightforward OE-style replacement.

Key Features

• Direct replacement exhaust gas recirculation (EGR) tube
• Stainless steel construction for corrosion resistance
• Built to resist stress fractures and carbon buildup blockage
• Threaded end 1 connection
• 20-inch length with 0.25-inch inside diameter and 0.63-inch outside diameter
• Two connectors, one hose/line, and no mounting hardware included
• Cross-reference part number: F6AZ9D477A

Detailed Description

This EGR tube is designed for emissions-system repair where the original exhaust gas recirculation line has cracked, corroded, or become restricted. Dorman 598-142 follows the original equipment layout and uses stainless steel to help maintain exhaust gas flow through the EGR circuit. It is a practical replacement for drivers servicing a Lincoln Town Car EGR tube, Ford Crown Victoria EGR line, or Grand Marquis EGR tube application.

Part number 598-142 is listed as a direct replacement for OE part F6AZ9D477A and is intended for vehicles that use the same tube configuration and connector layout.

What It Helps Fix

• EGR tube cracking from heat and vibration
• Corrosion-related exhaust leaks
• Carbon buildup that restricts EGR flow
• Failed emissions inspection caused by EGR line damage
• Rough running conditions related to EGR passage restriction

Installation Notes and Tips

Verify the threaded end, connector count, length, and tube diameter against the original part before installation. Inspect adjoining EGR components, fittings, and sealing surfaces for wear or blockage so the replacement tube can function correctly. Because mounting hardware is not included, reuse or source the required hardware as needed for the vehicle.

Quality Assurance

Dorman manufactures this EGR tube as a direct-fit replacement with the same general features and components as the original equipment tube. The stainless steel construction and OE-style design support a repair focused on fit, function, and emissions-system reliability.
