Product Details

The Dorman 904388 Exhaust Gas Recirculation (EGR) Cooler is a direct replacement component engineered to match the fit and function of the original EGR cooler on compatible Dodge Ram heavy-duty diesel trucks. This critical emissions system component cools exhaust gases before they are recirculated back into the engine, reducing combustion temperatures and harmful nitrogen oxide (NOx) emissions.

Key Features:

  • Direct replacement design ensures proper fit and function on specified applications
  • Durable construction using quality materials including stainless steel components for long service life
  • Rigorously tested through heat transfer testing, burst testing, and vehicle try-on validation
  • OEM benchmarking ensures reliable cooling performance and emissions control
  • Engineered to restore proper EGR system operation on heavy-duty diesel applications

This replacement EGR cooler addresses common failure symptoms including engine misfires, coolant loss, white smoke from the exhaust, and increased emissions. Backed by Dorman's century of automotive aftermarket experience and supported by a team of product engineers in the United States, this cooler provides a cost-effective repair solution for maintaining emissions compliance and engine performance. OEM reference number 68003399AA.
