Description and Operation 1-93
Turbocharger And Charge Air Cooler (CAC) Systems
Typical 6 Cylinder Turbocharger System — Air To Air Cooled (RWD Or 4WD)
Charge Air Cooler (CAC) System — Air To Liquid Cooled
The CAC system cools the intake air which has been heated by the turbocharger. The removal of heat from the pressurized air going into the CAC increases the air density which improves combustion efficiency, engine horsepower, and torque. The system consists of an additional CAC radiator in the grille, a reservoir, an electric water pump, the CAC located in the intake manifold, and tubing to interconnect these components. The CAC is positioned after the turbocharger directly in the flow of the intake air. As the heated air flows through the CAC, heat is transferred to the coolant which is circulated back to the CAC radiator to be cooled by the airflow through the grille. The CAC pump is controlled by PCM. The PCM maintains a desirable intake air temperature by monitoring the CAC coolant temperature sensor in the CAC radiator.
