The aftercooler is similar to a radiator. Coolant passes through the tubes in the aftercooler core. Inlet air that is warmed by the turbocharger compressor is directed through the aftercooler core. The air is cooled in the aftercooler.

Condensation can form in the passages of the aftercooler system. Drain plugs are provided for draining the moisture.
