The cooling system radiator is contains two separate cooling cores. The Charge Air Cooling (CAC) core cools the intake
combustion air from the turbocharger, and the engine coolant radiator core (RAD) cools the engine.
Cooling System: Core - Clean
On a cool engine with the coolant temperature is below 50°C (120°F), inspect the cooling system radiator cores for debris.
Clean the radiator cores, if necessary. Use compressed air, high-pressure water, or steam to remove dust and debris from the
radiator core. However, the use of compressed air is preferred.
