Dorman 904-002 EGR Cooler for 3.0L EcoDiesel Jeep Ram

The Dorman 904-002 is an OE FIX Exhaust Gas Recirculation (EGR) Cooler specifically designed to address common failure points in the factory EGR cooler on select Jeep Grand Cherokee SUVs and Ram 1500 trucks equipped with the 3.0L EcoDiesel engine. This patent-pending design offers a more permanent repair solution than dealership replacements.

Why the Factory EGR Cooler Fails:

Original equipment EGR coolers on these vehicles typically fail due to internal soot buildup caused by exhaust gases flowing too quickly over the fins in the factory design, preventing adequate cooling time. O-ring damage during installation of prior replacements is another common failure point.

Dorman's Improved Design Features:

• Helical restrictor and tube design slows exhaust gas flow to prevent soot accumulation and clogging
• Heat-resistant stainless steel construction for superior durability
• Revised gland design protects O-rings during installation and helps prevent leaks
• Reuses original equipment valve and actuator, eliminating the need to purchase the entire cooler assembly
• Direct-fit replacement engineered to match OE form, fit, and function

This Dorman OE FIX solution provides a cost-effective alternative to dealership repairs while addressing the root causes of EGR cooler failure in EcoDiesel applications.
