Charge Air Cooling
After the intake air passes through the air filter, it passes
through the turbocharger (A) that boosts the air pressure.
This process heats the air so it is passed through pipe (B)
to a cooler before entering the engine intake.
The cooler is located in the cooling box (C) behind the
radiator and should be cleaned daily with compressed air.
Refer to
Maintaining Engine Cooling Box, page 339
