Troubleshooting Test Steps Values Results
1. Inspect the Coolant Level
Coolant Level
Result: The coolant level is low.
Repair: Add coolant to the cooling system.
2. Check the Cooling System for Leaks
Leaks
Result: There are leaks in the cooling system.
Repair: Repair or replace the parts that are leaking.
Result: There are no leaks in the cooling system.
Proceed to Test Step 3
3. Check the Coolant Temperature Sensor
1. 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. Refer to Troubleshooting, "Sensor Signal (Analog, Passive) - Test".
Coolant Temperature Sensor
Result: The coolant temperature sensor reading is not reasonable.
Repair: Repair or replace the coolant temperature sensor.
Result: The coolant temperature sensor reading is reasonable.
Proceed to Test Step 4.
4. Pressure Test the Cooling System
A. 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.
Pressure Test
Result: The pressure test results are NOT OK.
Repair: If necessary, clean the components and/or replace the components.
Result: The pressure test results are OK.
Proceed to Test Step 5.
5. Check the Radiator
A. Check the radiator fins for dirt, debris, and/or damage.
B. Check the radiator for internal blockage.
C. Ensure that the radiator size is according to the OEM specifications. 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 NOT OK.
Repair: Repair or replace the radiator.
Result: The radiator is OK.
Proceed to Test Step 6.
6. Check the Engine Cooling Fan
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. Check the fan drive belt for proper belt tension.
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. Refer to Troubleshooting, "Cooling Fan Control - Test" for troubleshooting information.
