WARNING: This page is about a different car, the 2024 Jeep Grand Wagoneer L and 2024 Jeep Grand Wagoneer. However, it is still accessible from the selected car via links, so may be relevant.
To improve engine performance the Charge Air Cooler (CAC) system is used to reduce the temperature of the air entering the combustion chambers. The temperature increase of the air entering engine is caused by the Turbocharger. The Low Temp Cooling system consists of an electric Auxiliary Coolant Pump, Charge Air Cooler, Coolant Reservoir, Charge Air Cooler Radiator, Charge Air Cooler Coolant Temperature Sensor and plumbing. The Low Temp Cooling system operates independent of the vehicle's primary cooling system.
