1. Verify the Coolant Level
A. Verify that the coolant is filled to the correct level. If the coolant level is too low, air will get into the cooling system. Air in the cooling system will cause a reduction in coolant flow and pressure.
B. Check the cooling system for coolant leaks.
Coolant level
Result: The coolant level is correct.
Proceed to Test Step 2.
Result: The coolant level is not correct.
Determine the cause of the low coolant level. Refer to Troubleshooting, "Coolant Level Is Low". Verify that the problem has been corrected.
Return the unit to service.
2. Check the Cooling System Hose Routing
A. Check the cooling system clamps and hoses to make sure that they are installed in the proper location and the clamps are tight.
B. Ensure that there are no kinks or tight bends that may cause excessive restriction.
C. Check to make sure that the hoses are routed correctly.
Leaks or Kinks
Result: The coolant clamps and hoses are installed properly.
Proceed to Test Step 3.
Result: The coolant clamps and hoses are not installed properly.
Repair or replace the damaged cooling system component. Verify that the problem has been corrected. Return the unit to service.
3. Check the Expansion Tank (if equipped)
A. Check the shunt line for a restriction. A restriction of the shunt line from the expansion tank to the inlet of the jacket water pump will cause a reduction of water pump efficiency.
B. Inspect the expansion tank for a restriction that blocks the port to the shunt line.
Note: The expansion tank may be integrated into the design of the radiator top tank and may not be separate.
Shunt line
Result: The shunt line is properly installed and there are no restrictions.
Proceed to Test Step 4.
Result: The shunt line is not properly installed or there are restrictions.
Install the shunt line correctly or replace the line if necessary. Remove any restrictions that are found.
Verify that the problem has been corrected. Return the unit to service.
4. Check the Coolant Pressure Sensor For Accuracy
A. Install a mechanical pressure gauge in the coolant jacket near the coolant pressure sensor.
B. Start the engine.
C. Connect to the engine ECM using Cat® ET.
D. Allow the engine to run and record the pressure on the mechanical gauge.
E. Check the pressure reading at various engine speeds.
Coolant pressure sensor
Result: The pressure difference between the mechanical gauge and the reading in Cat® ET is less than 14 kPa (2 psi).
Proceed to Test Step 5.
Result: The pressure difference between the mechanical gauge and the reading in Cat® ET is greater than 14 kPa (2 psi).
Replace the coolant pressure sensor.
Verify that the problem has been corrected. Return the unit to service.
5. Check the Water Pump
A. Remove the water pump and check for a damaged or loose impeller, or a restriction in the water pump inlet or outlet ports.
Damaged impeller
Result: The water pump impeller is not damaged or loose and there are no restrictions.
Proceed to Test Step 6.
Result: The water pump impeller is damaged or loose, or there are restrictions.
Replace the water pump.
Verify that the problem has been corrected. Return the unit to service.
6. Check the Radiator or Heat Exchanger
A. Check the radiator or heat exchanger for a restriction. Check internally for dirt, debris, or deposits on the radiator core.
Restrictions
Result: There were deposits or restrictions in the radiator or heat exchanger.
Clean or replace the radiator or heat exchanger.
Verify that the problem has been corrected. Return the unit to service.
Result: There were no deposits or restrictions in the radiator or heat exchanger.
Proceed to Test Step 7.
7. Check the Oil Cooler
A. Check the inlet side of the oil cooler for debris or blockage.
Restrictions
Result: There was debris or restrictions in the oil cooler.
Clean or replace the oil cooler.
Verify that the problem has been corrected. Return the unit to service.
Complete the procedure in the order in which the steps are listed.
