Troubleshooting Test Steps    Values    Results    
1. Extreme Ambient Conditions
A. Make sure 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 2.
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.
   
2. Coolant
A. Inspect the coolant level.
B. Inspect the coolant for foaming or aeration.
   
Engine coolant level
   
Result: The engine coolant level is OK and there is no foam or aeration.
Proceed to Test Step 3.
Result: The engine coolant level is not OK.
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"
   
3. Coolant Temperature Sensor and/or the Circuit
A. Connect Cat ET.
B. Start the engine.
C. Check the reading of the coolant temperature on Cat ET. The temperature should rise steadily as the engine is warmed. Ensure that the temperature is reasonable.
   
Coolant temperature sensor
   
Result: The temperature sensor is working properly.
Proceed to Test Step 4.
Result: The temperature sensor is not working properly.
Troubleshoot the circuit and the coolant temperature sensor. Refer to Troubleshooting, "Sensor Signal (Analog, Passive) - Test".
   
4. Water Temperature Regulator and/or Pressure Relief Valve
A. Pressure-test the cooling system. Refer to Systems Operation/Testing and Adjusting for the correct procedure.
B. Check that the seating surfaces of the pressure relief valve and the radiator cap are clean and undamaged.
C. Check operation of the pressure relief valve and/or the water temperature regulator.
   
Temperature regulator
   
Result: The pressure relief valve and/or the water temperature regulator are operating properly.
Proceed to Test Step 5.
Result: The pressure relief valve and/or the water temperature regulator are not operating properly.
Repair: Clean the components and/or replace the components.
   
5. Radiator
A. Check the radiator fins for dirt, debris, and/or damage.
B. Check for collapsed hoses and/or other restrictions.
C. Check the radiator for internal blockage.
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 fins are not damaged and the radiator does not have an internal blockage.
Proceed to Test Step 6.
Result The radiator fins are damaged.
Repair: Remove any dirt and/or debris and straighten any bent fins.
Result The radiator has internal blockage.
Repair: Remove the blockage.
   
6. Faulty Engine Cooling Fan (if equipped)
A. If the fan is belt driven, check for loose drive belts.
A loose fan drive belt will cause a reduction in the air flow across the radiator.
B. Check the fan clutch, if equipped.
A fan clutch or a hydraulic driven fan that is not turning at the correct speed can cause improper air speed across the radiator core. The lack of proper air flow across the radiator core can cause the coolant not to cool to the proper temperature differential.
   
Fan belt or clutch
   
Result The fan belt is tensioned correctly and the fan clutch is operating correctly.
Proceed to Test Step 7.
Result The fan belt is not tensioned correctly.
Adjust the tension of the fan drive belt, if necessary. Refer to Operation and Maintenance Manual.
Result The fan clutch is not operating correctly.
Refer to Troubleshooting, "Cooling Fan Control - Test" for troubleshooting information.
   
7. Inspection of the Coolant Pump
A. Inspect the impeller of the coolant pump for damage and/or erosion.
B. Make sure that the drive gear is not loose on the drive shaft of the coolant pump.
   
Coolant pump
   
Result The coolant pump is operating correctly.
Contact your TC for assistance in finding the cause of the high coolant temperature.
Result The coolant pump is not operating correctly.
Repair: If necessary, replace the coolant pump. Refer to Disassembly and Assembly 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).
