The charge air cooler (CAC), also known as an intercooler, is a vital part of your International 4700 or 4900 diesel engine system. It works by cooling the compressed air from your turbocharger before it enters the engine. Cooler air means denser air, which improves combustion, boosts power, and increases fuel efficiency. If your CAC isn't performing like it should, your truck's performance, emissions, and fuel economy all take a hit.

What Does a Charge Air Cooler Do?

The charge air cooler on a diesel engine reduces the temperature of turbocharged air before it enters the intake manifold. This cooled air helps: - Improve horsepower and torque. - Reduce engine knock and stress. - Increase overall engine efficiency. - Lower emissions. It's a critical part of your intercooling system that ensures your turbocharged engine stays within safe operating temps, especially under heavy loads or long hauls.

Signs You Need a Replacement Charge Air Cooler

A bad or leaking CAC can lead to: - Loss of power and poor acceleration. - Increased exhaust smoke. - Higher fuel consumption. - Excessive heat in the engine bay. - Check engine light or fault codes related to boost pressure. A damaged CAC can also allow hot, unfiltered air or oil-contaminated air into the engine, potentially leading to long-term damage.
