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.

Result: The engine coolant level is not OK.

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, "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.
 

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).
