CUMMINS ISB 6.7L EGR Cooler For Sale (Part M4201384)
About This Cummins ISB 6.7L EGR Cooler
This is a good, used EGR cooler for the Cummins ISB 6.7L, carrying part number M4201384. The cooler lowers the temperature of recirculated exhaust gas before it returns to the intake, helping the engine's emissions system reduce nitrogen-oxide output. Internal cracks, leaks, or clogging can contribute to coolant loss, white smoke, overheating, fault codes, or poor operation. EGR coolers are matched to the engine's emissions specification, plumbing, and mounting arrangement, so model and year details matter when comparing replacements. Confirm the application and any listed part number against the cooler being removed. The part is inspected and tested before it ships, identified by its stock number (323381), and backed by included warranty coverage. Freight ships nationwide, quoted to your delivery ZIP. Use the page photos and listed details to compare it carefully with the component being replaced before purchase. Have your engine's year, make, model, and application ready and call (800) 696-5459 to confirm fitment before ordering.
