What an EGR Cooler Does

An EGR cooler lowers the temperature of exhaust gases before they are routed back into the intake system. This process helps reduce NOx emissions and supports compliance with modern diesel emissions regulations. A properly functioning EGR cooler is essential for maintaining engine performance and emissions system efficiency.

Common Engine Platforms Using EGR Coolers

EGR coolers are used across many heavy-duty diesel engines including:

• Cummins ISX, X15 and ISB 6.7 engines
• Detroit Diesel DD13, DD15 and DD16 engines
• Paccar MX-13 and MX-11 engines
• Volvo D11, D13 and D16 engines
• Mack MP7, MP8 and MP10 engines
• International A26 and MaxxForce engines
• Hino J08 and A09 engines

Common Signs of EGR Cooler Failure

• Coolant loss with no visible external leak
• White smoke from the exhaust
• Coolant contamination in the exhaust system
• EGR-related fault codes
• Engine overheating or temperature-related issues
• Check engine light and emissions derate conditions

A failing EGR cooler can lead to serious engine and aftertreatment issues if not replaced in time. Early diagnosis is important to avoid additional damage and costly downtime.

Why Correct Fitment Matters

EGR coolers are engine-specific and emissions-system specific. To confirm compatibility quickly provide:

• Engine serial number
• Current EGR cooler part number
• Year / Make / Model of truck
• VIN number if available
• Photos of the cooler tag if available
