SPRING 7M7316 - Caterpillar

The aftercooler is located at the center of the vee. The aftercooler has a coolant charged core assembly (assemblies). 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 assembly 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 (assemblies) which lowers the temperature. The cooler air flows out of the bottom of the aftercooler and into the air chamber. The air flows through the elbows to the inlet ports (passages) in the cylinder heads.
