Nissens 989447 Exhaust Gas Recirculation (EGR) Cooler

Exhaust Gas Recirculation Cooler Overview

The Nissens 989447 exhaust gas recirculation cooler is built for Mercedes-Benz Sprinter diesel applications that need controlled exhaust heat management. It uses a stacked-plate steel design and is evaluated for thermal performance under high-temperature, high-pressure exhaust flow conditions.

Key Features

• Steel construction for durability in exhaust system service.
• Stacked-plate design for efficient heat transfer.
• Thermal performance examined under exhaust-flow conditions.
• No gasket or seal included.
• No vacuum bypass included.

Detailed Description

This EGR cooler is engineered for emission control service on Mercedes-Benz Sprinter 2500, Sprinter 3500, and Sprinter 3500XD diesel models. 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.

Nissens 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.

What This Part Helps Address

• Restricted exhaust gas recirculation flow caused by internal buildup or wear.
• Loss of cooling efficiency in the EGR circuit.
• Emission system faults related to cooler performance.
• Heat management issues in the recirculation path.

Installation Notes and Tips

Verify fitment against the listed Mercedes-Benz Sprinter 2500, Sprinter 3500, and Sprinter 3500XD applications before ordering. This cooler does not include a gasket or seal, and it does not include a vacuum bypass. Inspect adjoining EGR components, seals, and mounting surfaces during replacement to help ensure proper system operation.

Quality Assurance

Nissens evaluates thermal performance under simulated exhaust-system conditions to verify the cooler’s behavior in high heat and pressure environments. Part number 989447 is built for emission control service where consistent heat exchange is required.
