| 1 | RH charge air cooler |
| 2 | Engine |
| 3 | LH (left hand) charge air cooler |
| 4 | Expansion hose connection (with engine cooling system) |

Electrical power for the charge air coolant pump is supplied from the intercooler water pump relay in the power distribution box. When the intercooler water pump relay is energized, it connects power from the battery, via the battery junction box (BJB) and central junction box (CJB), to the charge air coolant pump. Operation of the intercooler water pump relay is controlled by the engine control module (ECM). The intercooler water pump relay is energized continuously while the ignition is in power mode 6.
When the charge air coolant pump is running, coolant flows from the pump outlet through the charge air coolers, the charge air radiator and back to the pump inlet.
