7.8.5.2 Charge Air Cooling
After the intake air passes through the air filter, it
passes through the turbocharger (J) which
boosts the pressure. This process heats the air
so it is passed through pipe (K) to a cooler
before entering the engine intake. The cooler is
located in the cooling box (L) behind the radiator
and should be cleaned daily with compressed
air. Refer to Section 7.9.3, Cooling Box
Maintenance.
