The charge air coolant pump is an electric pump attached to the left side of the electric cooling fan shroud.

An electrical connector provides the interface between the motor of the charge air coolant pump and the vehicle wiring.

Electrical power for the charge air coolant pump is supplied from the Powertrain Control Module (PCM) relay, located in the right Engine Junction Box (EJB). When the PCM relay is energized, the PCM 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, coolant flows from the pump outlet through the charge air cooler. After the charge air cooler the coolant flows into the charge air radiator and back to the pump inlet connection.
