CAMSHAFT GP 2925867 - Caterpillar

order to find the cause of a high water temperature shutdown, perform the following procedure.
Check For The Diagnostic Fault.
Check for a CID 110 or CID 269 diagnostic code that is active. See Testing And Adjusting, "Troubleshooting Diagnostic Codes".Expected Result: CID 110 or CID 269 should not be showing. This means that CID 110 or CID 269 are not active.Results:
OK: Proceed to Step 2.
NOT OK: Correct the active CID 110 or CID 269 prior to proceeding with this procedure. See the topic Testing And Adjusting, "Troubleshooting Diagnostic Codes". STOP.
Check Obvious Causes.
Check the water level.
Check fan drive belts.
Check for other obvious causes of high water temperature.Expected Result: No obvious cause should exist.
OK: Proceed to Step 3.
NOT OK: An obvious cause exists. Correct the fault. Refer to the Engine Service Manual. STOP.
Check Setpoint P015.Note: Setpoint P015 describes high water temperature.
View setpoint P015. Make a note of setpoint P015. See System Operation, "Engine/Generator Setpoint Viewing OP2-0".
Compare the setpoints which are viewed with the specified setpoints of the particular generator set.Expected Result: The value of the setpoint that is viewed and the specified setpoint value should agree.Results:
OK: Proceed to Step 4.
NOT OK: The setpoints do not agree. Reprogram setpoint P015. See System Operation, "Engine/Generator Programming OP5-0". STOP.
Check The High Water Temperature Function.
Turn the engine control switch (ECS) to OFF/RESET. Then, turn the ECS to START.
Allow water temperature to stabilize.
Check and note the actual water temperature which is showing on the lower display.
Compare the temperature that is viewed on the lower display with setpoint P015. P015 is noted in Step 3.Expected Result: The actual temperature which is showing on the lower display should be less than setpoint P015. This actual temperature should not cause a high water temperature shutdown.Results:
OK: The actual temperature is less than the setpoint P015 and the high water temperature indicator does not FLASH. The problem is not present now. The problem may be intermittent. Check the harness. Check all of the electrical connections on the water temperature circuit. See Testing And Adjusting, "Electrical Connector - Inspect". STOP.
OK: The actual temperature is less than the setpoint P015 and the high water temperature indicator remains FLASHING. Therefore, the GSC+ is faulty. Replace the GSC+. See Testing And Adjusting, "EMCP Electronic Control (Generator Set) - Replace". STOP.
NOT OK: Actual temperature is greater than the setpoint P015. The temperature is correct for a high water temperature shutdown. The engine should be shutdown and the high water temperature indicator should FLASH. The GSC+ is operating properly. Refer to the Engine Service Manual in order to find the cause of high water temperature. STOP.Note: Check the accuracy of the temperature which is shown on the lower display of the GSC+. Install a temperature gauge as close as possible to the coolant temperature sensor. The temperature gauge must be in a high coolant flow.
