Coolant flows out of the filter base and into the EGR cooler through a tube that directs the coolant to the back of the EGR cooler.
Coolant flows through the EGR cooler and removes heat from the exhaust gasses before the exhaust arrives at the EGR valve.
Coolant exits the front of the EGR cooler and enters the coolant passage of the intake manifold. The intake manifold directs the coolant back into the front cover.
