Electrical power for the charge air coolant pump is supplied from the charge air coolant pump relay in the EJB (Engine Junction Box). When the relay is energized, it connects power from the battery to the charge air coolant pump. Operation of the relay is controlled by the ECM (Engine Control Module). The charge air coolant pump relay is energized continuously while the ignition is ON.
When the charge air coolant pump is running, coolant flows from the pump outlet through the charge air coolers, the charge air radiators and back to the pump intake.
