Cummins EGR Coolers
Cummins EGR coolers are critical components in the diesel emissions system, designed to reduce the temperature of exhaust gases before they are recirculated back into the engine. By lowering exhaust temperatures, the EGR cooler helps control NOx emissions and maintain stable combustion. At Advanced Truck Parts, we supply replacement EGR coolers for Cummins engines including ISX, X15, and ISB 6.7 platforms.

Cummins EGR Coolers by Engine Platform
EGR coolers work together with the EGR valve and other emissions components to regulate exhaust gas flow and temperature. Proper cooler function helps maintain engine efficiency and prevents excessive thermal stress on emissions system components.
Cummins ISX EGR Coolers
The Cummins ISX engine platform uses an EGR cooler to reduce exhaust gas temperatures before gases are routed back into the intake system. These coolers are exposed to high heat and soot buildup, which can eventually lead to clogging or internal failure.
- Cummins ISX CM871
- Cummins ISX CM2250
- Cummins ISX CM2350
A failing EGR cooler on ISX engines may cause coolant loss, white exhaust smoke, or emissions system faults.
Cummins X15 EGR Coolers
The Cummins X15 engine features an advanced emissions system that includes an EGR cooler designed to manage high exhaust temperatures while maintaining engine performance.
- Cummins X15 Efficiency Series
- Cummins X15 Performance Series
Proper EGR cooler function is essential to prevent overheating and maintain emissions compliance.
Cummins ISB 6.7 EGR Coolers
The Cummins ISB 6.7 engine uses a compact EGR cooler design commonly found in medium-duty trucks and various diesel applications. These coolers help regulate combustion temperatures and support emissions system performance.
- Cummins ISB 6.7 CM2150
- Cummins ISB 6.7 CM2350
- Medium-duty truck platforms
Common Cummins EGR Cooler Failure Symptoms
- Coolant loss without visible leaks
- White exhaust smoke
- Overheating issues
- Check engine light related to EGR system
- Exhaust gas or coolant contamination
Because EGR coolers operate under high thermal stress, failure can affect both the emissions system and overall engine performance.
Verify Fitment Before You Buy
Cummins EGR coolers must match the engine model and emissions configuration. To confirm compatibility before ordering, provide:
- Engine Serial Number (ESN)
- Truck year / make / model
- Engine model (ISX, X15, or 6.7)
- Current EGR cooler part number
This information allows our team to confirm the correct EGR cooler for your Cummins engine.
