Charge Air Cooler
WARNING: This page is about a different variant/trim than selected.
Electrical power for the charge air coolant pump is supplied from the PCM relay, located in the EJB . When the relay is energized, it connects power from the startup battery to the charge air coolant pump. Operation of the charge air coolant pump is controlled by the PCM with a Pulse Width Modulation (PWM) signal. When the charge air coolant pump is running, engine coolant flows from the pump outlet through the charge air cooler.
Afterwards to the charge air radiator and back to the pump inlet connection.
