Troubleshooting Test Steps    Values    Results    
1. Coolant
A. Inspect the coolant level.
   
Engine coolant level
   
Result: The engine coolant level is OK.
Proceed to Test Step 2.
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.
   
2. Coolant Temperature Sensor and/or the Circuit
A. 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 3.
Result: The temperature sensor is not working properly.
Troubleshoot the circuit and the coolant temperature sensor. Refer to Troubleshooting, "Sensor Signal (Analog, Passive) - Test".
   
3. 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 4.
Result: The pressure relief valve and/or the water temperature regulator are not operating properly.
Clean the components and/or replace the components.
   
4. 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 5.
Result The radiator fins are damaged.
Remove any dirt and/or debris and straighten any bent fins.
Result The radiator has internal blockage.
Remove the blockage.
   
5. Heat Exchanger
A. Check for sufficient flow and temperature of the cooling water through the heat exchanger.
   
Heat exchanger
   
Result The flow of cooling water is sufficient.
Proceed to Test Step 6.
Result The flow of cooling water is not sufficient.
Determine the location of the obstruction. If the temperature of the cooling water is too high, determine the cause. Ensure that the size of the heat exchanger is sufficient. Make the necessary repairs.
   
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.
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 operating correctly.
Proceed to Test Step 7.
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.
Proceed to Test Step 8.
Result The coolant pump is not operating correctly.
If necessary, replace the coolant pump. Refer to Disassembly and Assembly for the correct procedure.
   
8. Cylinder Head Gasket
A.Remove the cylinder head. Refer to the Disassembly and Assembly manual.
B. Check the cylinder liner projection. Refer to the Systems Operation/Testing and Adjusting manual.
C. Pressure test the head for leaks.
D. Install a new cylinder head gasket and new water seals in the spacer plate. Refer to the Disassembly and Assembly manual.
   
Head gasket
    Result The cylinder head was checked for leaks and the gasket was replaced.
Verify that the problem was corrected.
   Complete the procedure in the order in which the steps are listed. 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).
