Troubleshooting Test Steps Values Results
1. Diagnostic Codes
A. Use the electronic service tool to check for diagnostic codes that relate to the temperature in the cooling system.
Diagnostic Codes
Result: Diagnostic codes are not present.
Return the unit to service.
Result: Diagnostic codes are present.
Proceed to Test Step 2.
2. Coolant Level
A. Check the coolant level.
Engine coolant level
Result: The engine coolant level is low.
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 level is OK.
Proceed to Test Step 3.
3. Coolant Temperature Sensor
A. Compare the reading for the coolant temperature on the electronic service tool to the reading for the coolant temperature on a calibrated test gauge.
Coolant temperature sensor
Result: The temperature sensor is not accurate.
Repair: Troubleshoot the circuit and the coolant temperature sensor. Refer to Troubleshooting, "Sensor Signal (Analog, Passive) - Test".
Result: The temperature sensor is reading accurately.
Proceed to Test Step 4.
4. Radiator and Hoses
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 depends on the ambient temperature.
Radiator and hoses
Result: The radiator fins are blocked or damaged.
Repair: Remove any dirt and/or debris and straighten any bent fins.
Result: The radiator has internal blockage.
Repair: Remove the blockage.
Result: The radiator fins are not damaged and the radiator does not have an internal blockage.
Proceed to Test Step 5.
5. Radiator Cap and Pressure Relief Valve
A. Pressure-test the cooling system. Refer to Systems Operation, Testing, and Adjusting, "Cooling System" 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.
Radiator cap
Result: The pressure relief valve and/or the water temperature regulator are not operating correctly.
Repair: Clean the components or replace the components.
Result: The pressure relief valve and/or the water temperature regulator are operating correctly.
Proceed to Test Step 6.
6. Water Temperature Regulator
A. Check the water temperature regulator for correct operation. Refer to Systems Operation, Testing, and Adjusting, "Cooling System" for the proper procedure.
Water Temperature Regulator
Result: The water temperature regulator is not operating correctly.
Repair: Replace the water temperature regulator. Refer to Disassembly and Assembly, "Water Temperature Regulator - Remove and Install".
Result: The water temperature regulator is operating correctly.
Proceed to Test Step 7.
7. Engine Cooling Fan
A. Check that the cooling fan is operating correctly.
B. Check the engine cooling fan for damage.
Fan
Result: The cooling fan is not operating correctly.
Repair: Make sure that the cooling fan is being driven correctly. Make sure that the belt tensioner is
