Charge Air Coolers (CACs) for trucks and semis

Charge air coolers, often abbreviated to CACs and sometimes called intercoolers, are key parts of every truck and semi equipped with a turbocharger or a supercharger. CACs cool the compressed air generated by the turbo or supercharger before it enters the combustion chamber of the engine. 

CACs also increase the oxygen content of the compressed air, which increases combustion efficiency, decreases fuel consumption, and lowers emissions. It’s crucial to keep charge air coolers well-maintained to keep your truck running safe and optimal, reducing costs and lowering the risk of malfunctions

Maintaining a Charged Air Cooler (CAC)

A well-maintained CAC can make sure the engine receives a consistent stream of cool, dense air that promotes efficient combustion and improves your engine power. Without a functioning CAC, the engine can receive excessive hot air intake, leading to overheating and increased wear on engine components. 

Frequent inspections are necessary to find any signs of CAC damage. Look for any cracks, leaks, or bent fins. The damaged components should be replaced as soon as possible. Remember to regularly remove any dirt or debris that may have accumulated around the fins to keep the airflow efficient.

Carefully check the CAC hoses and piping for any signs of leaks to prevent pressure loss, and keep monitoring engine performance for any signs of issues to catch problems early on.
