The charge air cooler (CAC) in a Freightliner is an essential component of the engine's air intake system. Its primary function is to cool the compressed air from the turbocharger before it enters the engine's intake manifold resulting in a denser air, which increases the engine's efficiency and power output while reducing emissions as well as upholding the engine optimum fuel efficiency as per the manufacturer’s specifications.

Maintaining the charge air cooler is crucial for ensuring optimal engine performance and efficiency. Regular inspection and cleaning are necessary to prevent the buildup of dirt, debris, and other contaminants that can restrict airflow and reduce cooling efficiency. Additionally, any leaks or damage to the charge air cooler must be promptly repaired to prevent loss of boost pressure and increased fuel consumption. Find out more...
