What Is an EGR Cooler?
Mobile Mechanic • Canberra & ACT • Transparent Quotes
An EGR cooler (Exhaust Gas Recirculation cooler) lowers the temperature of exhaust gases before they are routed back into the intake. Cooling the exhaust helps reduce NOx emissions and improves combustion stability—especially on many modern diesel engines. Over time, EGR coolers can clog with soot/carbon, leak coolant internally, or crack, triggering warning lights and drivability issues.
What it does Cools recirculated exhaust gas to reduce NOx and keep intake temperatures controlled. Common failures Soot blockage, coolant leaks, internal cracks, sticking bypass valve, gasket leaks.
⚠️ Symptoms of an EGR cooler problem Coolant loss with no obvious external leak, white exhaust smoke/steam, overheating, rough idle, limp mode, DPF issues, or a check engine light related to EGR flow/temperature.
