Troubleshooting Test Steps    Values    Results    
1. Low Coolant Level and/or Coolant Leakage
A. Inspect the coolant level.
   
Coolant Level
   
Result: The engine coolant level is OK.
Proceed to Test Step 2.
Result: The engine coolant level is NOT OK.
Repair: Troubleshoot the cause of the incorrect coolant level.
1. Check for the correct mixture of antifreeze and water. Refer to Operation and Maintenance Manual.
2. Check the cooling system for leaks. Refer to Systems Operation/Testing and Adjusting, "Radiator and Cooling System - Test" for the correct procedure. Repair any leaks immediately.
3. Check for air in the cooling system. Refer to Systems Operation/Testing and Adjusting, "Testing the Cooling System" for the correct procedure.
Verify that the repair eliminated the problem.
   
2. Faulty Coolant Level Sensor
A. Check for proper operation of the coolant level sensor.
   
Coolant Level Sensor
   
Result: The coolant level sensor is not operating properly.
Repair: Replace the coolant level sensor.
Verify that the repair eliminated the problem.
   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).
