A Dura-Lite Charge Air Cooler (CAC) for a Mack truck plays the same critical role as on any heavy-duty diesel: it cools the turbo-compressed air before it enters the engine to improve power, fuel efficiency, and engine durability. Dura-Lite’s CAC designs are built for vocational strength, high boost, and tough off-road environments.

Mack trucks engines depend on a properly functioning CAC to:

• Reduce air temperature after turbo compression.
• Increase air density for stronger combustion.
• Improve torque and fuel economy.
• Lower exhaust temperatures (protecting the turbo, EGR, DPF, DOC).
• Prevent engine overheating and detonation.

A healthy CAC is essential on heavy-haul, construction, refuse, or off-road Mack applications.
