Exhaust Gas Recirculation (EGR) Cooler: Notes

The EGR cooler removes heat from the exhaust gases before the gases enter the intake manifold. The EGR cooler is located above the right hand valve cover. When the exhaust gases are directed through the EGR cooler, coolant from the engine cooling system reduces the exhaust gas temperature. The exhaust gases are directed through the EGR cooler by a PCM controlled EGR cooler bypass valve.
