Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: A code is active or logged.
Proceed to Test Step 2.
2. Check for High Inlet Air Temperature
A. Refer to Troubleshooting, "Intake Manifold Air Temperature Is High".
A one degree increase in the inlet manifold temperature will increase the exhaust temperature by approximately three degrees.
Inlet air
temperature
Result: The inlet air temperature is OK.
Proceed to test Step 3.
Result: The inlet air temperature is NOT OK.
Determine the cause of the high inlet air temperature and correct the problem.
If the problem is not resolved, proceed to the next step.
3. Check for High Exhaust Temperature
A. Inspect the turbine inlet temperature probes and thermowells on each side of the engine. Ensure that the temperature probes are reading correctly.
B. Refer to Test and Adjust, "Measuring Exhaust Temperature".
C. Install thermocouples or check individual cylinders with an infrared gun. Maintain a steady load and speed during the measurement to ensure an accurate comparison of each cylinder.
Exhaust
temperature
Repair: All cylinders have comparable temperatures.
Proceed to Test Step 4.
Result: One or more of the cylinders deviate significantly from the average temperature on that bank.
Proceed to step 7.
4. Check the Air Inlet System
A. Check the compressor inlet pressure for each turbocharger.
B. Check for restriction or blockage from the compressor discharge back to the engine.
C. Check for air leaks. Inspect all hoses, tubes, bellows, and clamps from air inlet to the inlet manifold.
Air inlet
Result: Compressor inlet pressures are equal on each turbocharger.
Check for boost side or exhaust side air leaks.
Proceed to Test Step 5.
Result: Compressor inlet pressures are not equal on each turbocharger.
Check for plugged air filters or restriction between the filter and the turbocharger compressor.
Result: The compressor discharge back to engine is OK.
Proceed to Test Step 5.
Result: The compressor discharge back to the engine is NOT OK.
Repair: Remove restriction or blockage.
Result: The engine has No Air Leaks.
Proceed to Test Step 5.
Result: The engine has Air Leaks.
Determine the cause of the air leak and repair damage or leaking components.
If the problem is not resolved, proceed to the step 5.
5. Check the Exhaust System
A. Refer to Test and Adjust, "Restriction of Air Inlet and Exhaust".
B. Inspect the exhaust system lines and all hoses, tubes, bellows connections from the exhaust manifold to the muffler. Also, inspect the bellows for cracks or loose clamps. Spray the joints with soapy water and inspect for leaks.
C. Verify that all the bellows have the correct orientation. Ensure that the arrow on the bellows is pointing in the correct direction of exhaust flow.
Exhaust system
Result: The air system lines and connections are OK.
Proceed to Test Step 6.
Result: The air system lines and connections are NOT OK.
If anything is loose or cracked replace or repair any issues.
If the problem is not resolved, proceed to the step 6.
6. Check the Aftercooler (If Equipped)
A. Normal intake manifold pressure with high exhaust temperature can be caused by blockage of the fins of the aftercooler core.
B. Check for leaks and/or damage to the aftercooler.
Aftercooler
Result: The aftercooler is OK.
Proceed to Test Step 7.
Result: The aftercooler is NOT OK.
Repair: Clear restrictions and replace aftercooler or any damaged lines.
If the problem is not resolved, proceed to Test Step 7.
7. Check the Fuel Injectors
Faulty injectors that deliver too much fuel will increase exhaust temperatures.
A. Connect Cat ET to determine if any diagnostic codes for the injector solenoids are present.
B. Perform the "Injector Solenoid Test". Check that the injector solenoids are "OK" on Cat ET.
C. Perform the "Cylinder Cutout Test". Locate the misfiring cylinder and correct the problem.
Leak
Result: The injectors are OK.
Proceed to Test Step 8.
Result: The injectors are NOT OK.
Repair: Repair or replace the faulty injectors.
If the problem is not resolved, proceed to Test Step 8.
8. Inspect Turbochargers
A. Inspect turbine and compressor wheels for visible signs of damage or rubbing.
B. Inspect turbochargers and turbocharger housings for leaks.
Turbocharger
Result: The turbochargers are OK.
Proceed to Test Step 9.
Result: The turbochargers are NOT OK.
Repair: Repair the turbochargers or replace, if necessary. Refer to the engine Disassembly and Assembly manual for details.
If the problem is not resolved, proceed to Test Step 9.
9. Valve Train Inspection
A. Inspect Hydraulic Lifters to ensure that valve train is functioning correctly.
B. Inspect Valve train components for damage or wear.
Valve Train
Result: The valve train is OK.
Result: The valve train is NOT OK.
Repair: Repair the valve train or replace, if necessary. Refer to the engine Disassembly and Assembly manual for details.
Verify that the repair eliminated the problem.
