BALL BEARING 1292380 - Caterpillar

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 Codes" 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
CoolantWater Temperature Regulator and/or Pressure Relief Valve
Water temperature regulator
Pressure relief valveEngine Cooling Fan (if equipped)
Faulty engine cooling fan (if equipped)Coolant Pump
Inspection of the coolant pumpCoolant Temperature Sensor
Coolant temperature sensor and/or the circuitRecommended Actions
Coolant
Inspect the coolant level. If necessary, add coolant.
Check for the correct 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, "Cooling System" 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.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.Inspection of the Coolant Pump
Inspect the impeller of the coolant pump for damage and/or erosion.
Make sure that the drive gear is not loose on the drive shaft of the coolant pump.
If necessary, replace the coolant pump. Refer to Disassembly and Assembly for the correct procedure.Coolant Temperature Sensor and/or the Circuit
Check the reading of the coolant temperature on Cat ET. The temperature should rise steadily as the engine is warmed. Ensure
