Electrical power for the charge air coolant pump is supplied from the charge air coolant pump relay in the Engine Junction Box 1 (EJB 1). When the ignition is switched ON, the charge air coolant pump relay is energized and provides power to the charge air coolant pump. Operation of the charge air coolant pump is controlled with a Pulse Width Modulation (PWM) signal by the Powertrain Control Module (PCM).
During operation, engine coolant flows from the outlet of the charge air coolant pump through the supercharger charge air coolers to the charge air radiator. The engine coolant then flows back to the inlet of the charge air coolant pump.
