Inspect the radiator for plugged radiator fins.

Use 550 kPa [80 psi] air pressure to blow the dirt and debris from the fins. Blow the air in the opposite direction of the fan air flow.

Inspect the CAC and the clearance between the CAC and the radiator for trapped debris. Remove if necessary.

Remove any debris found.

Inspect the radiator for bent or broken fins.

NOTE: If the radiator must be replaced due to bent or broken fins which can cause the engine to overheat, refer to the OEM service manual.

Inspect the radiator for core and gasket leaks.

WARNING  If a liquid refrigerant system must be removed before removing the radiator, wear eye and face protection. Wrap a cloth around the fittings before removing. Liquid refrigerant can cause serious eye and skin injury.
