Information:
Use this procedure in order to troubleshoot high coolant temperature or use this procedure if one of the following event codes is active. Refer to Troubleshooting, "Event Code List" for information about event codes and the default trip points for these codes. You must access the monitoring system on Caterpillar Electronic Technician (ET) in order to view the current trip points for these codes.
Table 1
Event Code
Code and Description Conditions which Generate this Code System Response
E361(1) High Engine Coolant Temperature The engine coolant temperature has exceeded the trip point and the delay time has expired. The code is logged.
E361(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.
The derate is 25 percent for every degree over the trip point. The maximum derate is 100 percent.
E361(3) High Engine Coolant Temperature The engine coolant temperature has exceeded the trip point and the delay time has expired. 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
Coolant
Inspect the coolant level. If necessary, add coolant.
Check the mixture of antifreeze and water. Refer to Operation and Maintenance Manual.
Check the cooling system for leaks. Repair any leaks immediately.
Check for air in the cooling system. Refer to Systems Operation/Testing and Adjusting for the correct procedure. Water Temperature Regulator and/or Pressure Relief Valve
Pressure test the cooling system. Refer to Systems Operation/Testing and Adjusting for the correct procedure.
Check that the seating surfaces of the pressure relief valve and the radiator cap are clean and undamaged.
Check operation of the pressure relief valve and/or the water temperature regulator. If necessary, clean the components and/or replace the components. Radiator or Heat Exchanger
Radiator
Check the radiator fins for dirt, debris, and/or damage. Remove any dirt and/or debris and straighten any bent fins. Check for collapsed hoses and/or other restrictions.
Check the radiator for internal blockage. Refer to Systems Operation/Testing and Adjusting for more information. Heat Exchanger
Check for sufficient flow and temperature of the cooling water through the heat exchanger. If the flow of cooling water through the heat exchanger is insufficient, determine the location of the obstruction. If the temperature of the cooling water is too high, determine the cause. Make the necessary repairs.Faulty Engine Cooling Fan (if equipped)
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. Adjust the tension of the fan drive belt, if necessary. Refer to Operation and Maintenance Manual.
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. Coolant Pump
Inspect the impeller of the coolant pump for
