Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A code is active or logged.
Proceed to Test Step 2.
2. Check for Insufficient Flow of Air Through the Air-to-Air Aftercooler
A. Determine the pressure differential of the inlet air across the air-to-air aftercooler (ATAAC). For specific data, refer to the TMI for your engine.
Restriction
Result: The pressure differential is NOT OK.
Repair: Clean or replace the ATAAC.
Verify that the repair eliminated the problem.
3. Check the Operation of the Cooling Fan
A. Verify that the engine cooling fan is working properly.
B. If the fan is belt driven, verify that the belt tension is adequate. Also, verify that the clutch is operating properly.
C. If the fan is hydraulically driven, verify that there is no leakage around the motor and that the pressure for the fan is adequate.
Cooling Fan
Result: The fan drive system is working properly.
Return the engine to service.
Result: The fan drive system is not working properly.
Repair: If the fan is belt driven, perform the necessary adjustments or perform any necessary repairs to the clutch or the belt tensioner.
If the fan is hydraulically driven, repair any leaks that have been discovered. Ensure that the control system for the fan is operating properly
Return the engine to service.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
