Charge-Air Cooler System
The charge-air cooler (CAC) (Figure 7-7) is used to cool
engine air after it has passed through a turbocharger, but
before it enters the engine. The charge-air cooler provides
better horsepower, increased fuel efficiency, and reduces
engine emissions.
The CAC system consists of the ducting to and from the
charge-air cooler and an engine driven fan. The charge-air
cooler system must be air-tight in order to work efficiently.
The ducting consists of metal tubing, hose clamps and
bellows. The recommended installation torque of the spring
loaded T-bolt clamps is 100 lb-in (11.3 Nm). Do not
compress the spring completely, the bellows and/or clamp
may be damaged from thermal expansion of the CAC tube.
Maintenance
Check the hose clamps for proper torque.
Inspect the bellows for cracks or holes.
Clean the charge-air cooler, removing any dirt or debris.
Verify the fan is operating correctly.
