Coolant level
Radiator cap and/or pressure relief valve
Water temperature regulator
Engine cooling fan
Coolant pumpRecommended Actions
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.Coolant Level
Pressurized System: Hot coolant can cause serious burns. To open the cooling system filler cap, stop the engine and wait until the cooling system components are cool. Loosen the cooling system pressure cap slowly in order to relieve the pressure.
Inspect the coolant level. If necessary, add coolant.
Compare the coolant temperature from Cat ET to the coolant temperature from a calibrated test gauge. If necessary, troubleshoot the circuit and the coolant temperature sensor. Refer to Troubleshooting, "Sensor Signal (Analog, Passive) - Test".
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.Radiator Cap and/or Pressure Relief Valve
Pressure test the cooling system. Refer to Systems Operation/Testing and Adjusting.
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 radiator cap. If necessary, clean the components and/or replace the components.Water Temperature Regulator
Check the water temperature regulator for correct operation. Refer to Systems Operation/Testing and Adjusting. If necessary, replace the water temperature regulator. Refer to Disassembly and Assembly.Engine Cooling Fan
Make sure that the engine cooling fan is correctly installed.
Make sure that the engine cooling fan is being driven correctly. Refer to Disassembly and Assembly.
Check the engine cooling fan for damage. If necessary, replace the fan. Refer to Disassembly and Assembly.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.
