The stacked-plate layout supports heat exchange within the recirculation circuit, while the steel body is suited to the demands of hot exhaust gas flow. Part number 989447 is a direct reference for buyers replacing a worn or restricted cooler in the Sprinter platform, and it cross-references Mercedes-Benz numbers 6511400675 and 6511400700 for the same application.\u003c\/p\u003e\u003cp\u003eNissens tests thermal performance to reflect the high-temperature and pressure conditions found in exhaust systems, which is important when selecting an EGR cooler for Mercedes-Benz Sprinter service. If you are sourcing a replacement for a Mercedes-Benz Sprinter 2500 or Sprinter 3500, confirm the vehicle’s exact configuration against the listed fitment before installation. Part number 989447 is also referenced by A6511400675 and A6511400700.\u003c\/p\u003e\u003ch2\u003eWhat This Part Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestricted exhaust gas recirculation flow caused by internal buildup or wear.\u003c\/li\u003e\n\u003cli\u003eLoss of cooling efficiency in the EGR circuit.\u003c\/li\u003e\n\u003cli\u003eEmission system faults related to cooler performance.\u003c\/li\u003e\n\u003cli\u003eHeat management issues in the recirculation path.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify fitment against the listed Mercedes-Benz Sprinter 2500, Sprinter 3500, and Sprinter 3500XD applications before ordering.
