Personal injury can result from hot coolant, steam and alkali.At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.Remove filler cap slowly to relieve pressure only when engine is stopped and radiator cap is cool enough to touch with your bare hand.Cooling System Conditioner contains alkali. Avoid contact with skin and eyes.

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. Verify that the Engine is not Operating in Extreme Ambient Conditions
Ambient Conditions
Result: The engine is not operating in extreme conditions.
Proceed to Test Step 3.
Result: The engine is operating in extreme conditions.
Refer to Operation within the safety section of the Operation and Maintenance Manual (OMM) for the safe operating temperature range.
If the problem is not resolved, proceed to Test Step 3.
3. Check the Coolant Level
Coolant Level
Result: The coolant level is OK. There is no foam or aeration.
Proceed to Test Step 4.
Result: The coolant level is NOT OK.
Repair: Check the cooling system for leaks. Refer to Troubleshooting, "Coolant Level is Low" for additional information. Repair any leaks immediately.
Result: The engine coolant contains foam or aeration.
Repair: Repair the condition that is causing the foam or aeration. Refer to Test and Adjust, "Testing the Cooling System"
If the problem is not resolved, proceed to Test Step 4.
4. Check the Coolant Temperature Sensor
Note: The sensor may be indicating an incorrect temperature that is within the normal range of the sensor.
A. Connect Cat ET.
B. Use Cat ET to monitor the following temperature:
- Coolant temperature
Note: The temperature should rise steadily as the engine is warmed.
C. Ensure that the temperature is reasonable.
D. Reference the reading to another temperature indicator when possible. Refer to Testing and Adjusting, "Testing the Cooling System" for additional information.
Sensor
Result: The temperature sensor is OK.
Proceed to Test Step 6.
Result: The temperature sensor is NOT OK.
If the problem is not resolved, proceed to Test Step 5.
5. Inspect the Electrical Connectors and the Wiring
A. Turn the main disconnect switch to the OFF position.
B. Thoroughly inspect the connectors. Refer to Troubleshooting, "Electrical Connectors-Inspect" for additional information.
C. Perform a 45 N (10 lb) pull test on the connector wires.
D. Check the harness for abrasions and pinch points.
Connectors and Wiring
Result: The connectors and wiring appear to be OK.
Repair: Replace the sensor.
If the problem is not resolved, proceed to Test Step 6.
Result: There is a problem with the connectors and/or wiring.
Repair: Repair or replace the connectors or wiring. Ensure that all the seals are properly in place and ensure that the connectors are coupled.
If the problem is not resolved, proceed to Test Step 6.
6. Check the NOx Reduction System (NRS) Cooler Leak
A. Refer to Testing and Adjusting, "Exhaust Cooler (NRS) - Test" for additional information.
NRS Cooler
Result: An NRS cooler has a leak.
Proceed to Test Step 7.
Repair: Replace the failed NRS cooler. Refer to Disassembly and Assembly manual for additional information.
Result: The NRS coolers do not leak.
If the problem is not resolved, proceed to Test Step 7.
7. Inspect the Pressure Relief Valve
A. Pressure-test the cooling system. Refer to Testing and Adjusting, "Testing the Cooling System" for additional information.
B. Check that the seating surfaces of the pressure relief valve and the radiator cap are clean and undamaged.
Relief Valve
Result: The pressure relief valve and the radiator cap are operating correctly.
Proceed to Test Step 8.
Result: The pressure relief valve or the radiator cap is not operating correctly.
Repair: Clean or replace damaged pressure relief valve or the radiator cap.
If the problem is not resolved, proceed to Test Step 8.
8. Check the Water Temperature Regulators
Note: The water temperature regulators should not begin to open until jacket water reaches opening temperature for the regulators.
A. Allow the engine to cool and then start the engine. Check the hose at the outlet for the jacket water. If the hose is warm and normal operating temperature is not achieved yet, a regulator may be stuck open.
B. If the water temperature regulators are malfunctioning, check the water temperature regulators. Refer to Testing and Adjusting, "Testing the Cooling System" for additional information.
Regulators
Result: The temperature regulators are OK.
Proceed to Test Step 9.
Result: The temperature regulators are NOT OK.
Repair: Replace the water temperature regulators.
If the problem is not resolved, proceed to Test Step 9.
9. Check the Radiator for Problems
A. Check the cooling fins on the radiator for dirt and for debris.
B. Check for sufficient flow and temperature of the cooling water through the radiator.
C. Ensure that the size of the radiator is sufficient.
Ensure that the radiator size is sufficient. An undersized radiator does not have enough area for the effective release of heat. An undersized radiator may cause the engine to run at a temperature that is higher than normal. The normal temperature is dependent on the ambient temperature.
Radiator
Result: The radiator is OK.
Proceed to Test Step 10.
Result: A problem with the radiator has been discovered.
Repair: If the temperature of the cooling water is too high, determine the cause. Clean the components or replace the radiator.
If the problem is not resolved, proceed to Test Step 10.
