PLATE AS 4559045 - Caterpillar

aftercooler is located at the center of the vee. The aftercooler has a core assembly that is charged with coolant. Coolant from the water pump flows through a pipe into the aftercooler. Coolant then flows through the core assembly (assemblies). Coolant flows back out the aftercooler through a different pipe.There is a connector (tube) that connects the bottom rear of each core to the cylinder block. This connector is used in order to drain the aftercooler when the coolant is drained from the engine.Inlet air from the compressor side of the turbochargers flows into the aftercooler through pipes. The air then passes through the fins of the core assembly which lowers the temperature. The cooler air flows out of the bottom of the aftercooler and into the inlet manifold. The air flows upward through the elbows to the inlet ports (passages) in the cylinder heads.There are sensors for the aftercooler water temperature and for the inlet manifold air temperature.
