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 the Coolant Level
Note: If the coolant level is too low, air will get into the cooling system. Air in the cooling system will cause a reduction in coolant flow and pressure.
A. Check the cooling system for coolant leaks.
Coolant Level
Result: The coolant level is OK.
Proceed to Test Step 3.
Result: The coolant level is NOT OK.
Repair: Determine the cause of the low coolant level. Refer to Troubleshooting, "Coolant Level Is Low" for additional information.
If the problem is not resolved, proceed to Test Step 3.
3. Check the Cooling System Hose Routing
A. Check the cooling system clamps and hoses to make sure that the clamps and hoses are installed in the proper location and the clamps are tight.
B. Ensure that there are no kinks or tight bends that may cause excessive restriction.
C. Check to make sure that the hoses are routed correctly.
Leaks or Kinks
Result: The coolant clamps and hoses are installed properly.
Proceed to Test Step 4.
Result: The coolant clamps and hoses are not installed properly.
Repair: Repair or replace the damaged cooling system component.
If the problem is not resolved, proceed to Test Step 4.
4. Check the Expansion Tank
A. Check the shunt line for a restriction. A restriction of the shunt line from the expansion tank to the inlet of the jacket water pump will cause a reduction of water pump efficiency.
B. Inspect the expansion tank for a restriction that blocks the port to the shunt line.
Note: The expansion tank may be integrated into the design of the radiator top tank and may not be separate.
Shunt Line
Result: The shunt line is properly installed and there are no restrictions.
For a E2112 or 109 code, proceed to Test Step 5.
For a E563 or 1937 code, proceed to Test Step 6.
Result: The shunt line is not properly installed or there
