This is an Illustration of the Cross Section View of the Aftercooler (Typical Example). (1) Coolant outlet port (2) Coolant inlet port (A) Coolant to the Inlet (B) Coolant to the OutletThe aftercooler is located in the center of the Vee and the aftercooler has core assemblies that are charged with coolant. Coolant from the water pump on the left side of the engine flows through the coolant inlet port (2). Coolant circulates through the core assemblies and the coolant leaves the aftercooler through the coolant outlet port (1) .Inlet air from the compressor side of the turbocharger flows into the aftercooler housing and the inlet air passes the fins in the core assemblies. The aftercooler cores lower the temperature of the air. The cooler air goes out of the bottom of the aftercooler into the air plenum and the air goes up through the inlet ports of the cylinder heads.
