The Kenworth T880 and Kenworth T680 both use a Charge Air Cooler (CAC) as part of their air-to-air aftercooling system. Here’s a breakdown for both models:

Kenworth T880 Charge Air Cooler (CAC)

• Designed for vocational and heavy-haul applications (construction, logging, bulk haul).
• Built to withstand higher loads, vibrations, and dirty environments.
• Often paired with PACCAR MX-13 or MX-11 engines, though some may run Cummins X15.
• Heavy-duty core design to resist leaks from extreme heat cycles and stress.

Kenworth T680 Charge Air Cooler (CAC)

• Aerodynamic on-highway tractor, focused on fuel efficiency and long-haul reliability.
• CAC optimized for airflow and cooling efficiency to complement the T680’s aerodynamic design.
• Typically paired with PACCAR MX-13, MX-11, or Cummins X15 engines.
• Emphasis on durability with lighter weight to maximize fuel economy.
