FAQ'S

What Mack truck models are compatible with your charge air coolers?
Our coolers support a wide range of Mack models, including Titan, Granite, Pinnacle, and Anthem, offering matching mounting points, inlet/outlet alignment, and airflow performance.

What is the difference between bar & plate and tube & fin charge air coolers?
Bar & plate coolers are more robust and resist clogging and thermal fatigue, making them ideal for demanding duty and high-boost use. Tube & fin coolers are lighter and efficient for moderate load applications.

How do I choose the correct charge air cooler for my Mack engine?
Compare the OEM part number or measure your existing cooler’s size, inlet/outlet configuration, airflow capacity, and boost requirements. Then align to the specs shown in our catalog to select the appropriate replacement.

Can I replace only the cooler without replacing other components?
Yes — you can typically replace just the cooler if your existing hoses, clamps, and ducting are still in good condition. However, replacing the entire charge air system often yields better long-term performance.

What symptoms suggest a failing Mack charge air cooler?
Look for signs such as reduced engine power or boost, increased exhaust smoke, elevated intake air temperatures, visible oil or coolant leaks, or damage to fins. These point to performance loss and failing cooling capacity.
