2881692 | Genuine OEM Cummins ISB 6.7L EGR Cooler Kit

The Genuine OEM Cummins 2881692 EGR Cooler Kit is designed for compatible Cummins ISB 6.7L diesel engines used in commercial trucks and other heavy-duty applications. This exhaust gas recirculation cooler helps reduce the temperature of recirculated exhaust gases before they return to the engine intake system.

As part of the engine's emissions control system, the EGR cooler supports proper exhaust gas temperature management and helps reduce nitrogen oxide (NOx) emissions.

APPLICATIONS

The Cummins 2881692 EGR Cooler Kit is associated with selected Cummins ISB 6.7L diesel engine applications.

Potential applications include:

• Cummins ISB 6.7L Diesel Engines

• Medium-Duty Commercial Trucks

• Heavy-Duty Commercial Vehicle Applications

• Selected Commercial Buses

• Other Equipment Equipped with Compatible Cummins ISB 6.7L EGR Systems

Replacement catalogs identify applications within the 2011–2018 Cummins ISB 6.7L engine family.

Important: Compatibility depends on the engine serial number, emissions configuration, original cooler design, and OEM part number. Not all Cummins 6.7L EGR coolers are interchangeable.

FUNCTION

The Cummins 2881692 EGR Cooler Kit is part of the exhaust gas recirculation system.

The EGR cooler transfers heat from recirculated exhaust gases to the engine cooling system before those gases are introduced into the intake stream. Lowering exhaust gas temperature helps control combustion temperatures and reduce NOx emissions.

A worn, damaged, or failing EGR cooler may cause symptoms such as:

• Engine coolant loss without an obvious external leak

• White exhaust smoke or steam caused by coolant entering the exhaust system

• EGR system diagnostic trouble codes

• Reduced engine performance or power derating

• Exhaust gas recirculation temperature irregularities

• Engine overheating or cooling system problems

WHY REPLACE AN EGR COOLER KIT?

A leaking, cracked, or restricted EGR cooler can interfere with exhaust gas temperature control and affect the operation of the engine's emissions system.

Replacing a defective cooler with the correct Genuine OEM Cummins 2881692 EGR Cooler Kit helps restore intended exhaust gas cooling and EGR system performance.

Proper EGR cooler operation supports emissions compliance, reliable engine operation, and appropriate temperature management in the exhaust gas recirculation circuit.
