Event Code
Code and Description Conditions which Generate this Code System Response
E017(1) High Engine Coolant Temperature The engine coolant temperature has exceeded the trip point and the delay time has expired. The code is logged.
E015(2) High Engine Coolant Temperature The engine coolant temperature has exceeded the trip point and the delay time has expired. Engine power is derated. The code is logged.
Derate is 25 percent for every degree over the trip point. Probable Causes
Low coolant level and/or coolant leakage
Water temperature regulator and/or pressure relief valve
Radiator or heat exchanger
Engine cooling fan (if equipped)
Coolant pump
Coolant temperature sensorRecommended Actions

Troubleshooting Test Steps Values Results
1. Coolant
A. Inspect the coolant level.
B. Check for the correct mixture of antifreeze and water. Refer to Operation and Maintenance Manual.
C. Check the cooling system for leaks. Repair any leaks immediately.
D. Check for air in the cooling system. Refer to Systems Operation/Testing and Adjusting for the correct procedure.
Engine coolant level
Result: The engine coolant level, and coolant mixture is OK.
Proceed to Test Step 2.
Result: The coolant level, and coolant mixture are NOT OK.
Make the necessary repairs. Verify that the problem is resolved.
2. 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 3.
Result: The pressure relief valve and/or the water temperature regulator are not operating properly.
Clean the components and/or replace the components.
3. Radiator or Heat Exchanger
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 4.
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.
4. 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 5.
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.
5. 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 6.
Result: The coolant pump is not operating correctly.
If necessary, replace the coolant pump. Refer to Disassembly and Assembly for the correct procedure.
6. Check the 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.
Result: The temperature sensor is not working properly.
Troubleshoot the circuit and the coolant temperature sensor. Refer to Troubleshooting, "Sensor Signal (Analog, Passive) - Test".
