Symptomsof a worn, clogged or faulty EGR cooler. Engine overheating: if coolant flow is restricted, the EGR cooler is unable to cool the exhaust gases. This not only allows NOx emissions to continue, it also causes overheating which can cause serious damage. Loss of coolant from the cooling system: this could be causing an internal leak
