Charge Air Cooler (CAC) - Air To Liquid Cooled
WARNING: This page is about a different car, the 2020 Ford F-550 Super Duty, 2020 Ford F-450 Super Duty, 2020 Ford F-350 Super Duty, 2020 Ford F-250 Super Duty, and 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The CAC is composed of an air to liquid heat exchanger mounted next to the engine on the driver side of the vehicle and the tubing used to connect the output of the turbocharger to the intake of the engine. The CAC is designed to cool the induction air which has been heated by the turbocharger. As the heated air flows through the CAC, heat is transferred to the coolant reducing the temperature of the intake air.
