Dorman 904-002 Exhaust Gas Recirculation (EGR) Cooler

Dorman 904-002 EGR Cooler for EcoDiesel

Dorman 904-002 is an OE FIX exhaust gas recirculation cooler for select Jeep Grand Cherokee and Ram 1500 EcoDiesel 3.0L applications. It addresses common factory cooler failure points with an updated internal flow design while retaining the factory valve and actuator for a more direct repair.

Key Features

• OE FIX design for a more permanent EGR cooler repair
• Tube-and-helical restrictor construction slows exhaust flow to reduce soot buildup
• Rugged stainless steel construction for heat resistance
• Uses the revised gland design found on later OE versions to help protect O-rings during installation
• Specific fit for 2014-2018 Ram 1500, 2015-2019 Jeep Grand Cherokee, and 2019 Ram 1500 Classic
• Part number 904-002 for easy identification during ordering and service lookup

Detailed Description

This Dorman EGR cooler is engineered for vehicles where the original cooler has failed from internal soot accumulation or from O-rings damaged during a prior installation. By routing exhaust gases through tubes and a helical restrictor, the cooler slows gas velocity and helps limit clogging in the heat exchanger. The design also reuses the factory valve and actuator, which can reduce the need to replace the entire assembly. This makes Dorman 904-002 a practical choice for Jeep Grand Cherokee and Ram 1500 owners seeking a direct-fit emission control repair.

This part cross-references 6700102 and 68239570AC for the same application.

What It Helps Address

• EGR cooler leaks caused by internal soot buildup
• Restricted exhaust gas flow through a clogged cooler core
• O-ring damage from improper or repeated cooler installation
• Cooling performance loss in the exhaust gas recirculation system
• Need for a replacement that reuses the factory valve and actuator

Installation Notes and Tips

Verify vehicle application before installation. This cooler is a specific-fit replacement for 2014-2018 Ram 1500, 2019 Ram 1500 Classic, and 2015-2019 Jeep Grand Cherokee models equipped with the EcoDiesel 3.0 engine. Follow factory service procedures, inspect sealing surfaces carefully, and replace gaskets and O-rings as required during service to help prevent repeat leaks.

Quality Assurance

Dorman designs this OE FIX cooler as a service solution for known failure points in the original EGR cooler design. It uses stainless steel construction and a revised gland layout aligned with later OE updates for improved installation protection.
