Recommended Actions
Steam or hot coolant can cause severe burns.Do not loosen the filler cap or the pressure cap on a hot engine.Allow the engine to cool before removing the filler cap or the pressure cap.
Table 2
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 the Coolant Level
Coolant Level
Result: The coolant level is OK.
Proceed to Test Step 3.
Result: The coolant level is NOT OK.
Repair: Add coolant. Determine the cause of the low coolant level.
If the problem is not resolved, proceed to Test Step 3.
3. Check the Cooling System for Leaks
A. Inspect the coolant for presence of bubbles.
Leaks
Result: No presence of bubbles and the cylinder liners are OK.
Proceed to Test Step 4.
Result: There is leakage and/or the cylinder liners are damaged.
Repair: Repair any leaks. Replace any damaged cylinder liners.
If the problem is not resolved, proceed to Test Step 4.
4. Check the Heat Exchanger for Problems
A. Check the cooling fins on the heat exchanger for dirt and for debris.
B. Check for sufficient flow and temperature of the cooling water through the heat exchanger.
C. Ensure that the size of the heat exchanger is sufficient.
Heat Exchanger
Result: The heat exchanger is OK.
Proceed to Test Step 5.
Result: A problem with the heat exchanger has been discovered.
Repair: If the temperature of the cooling water is too high, determine the cause. Clean the components or replace the heat exchanger.
If the problem is not resolved, proceed to Test Step 5.
5. Check the Coolant Temperature Sensor
Note: The sensor may be indicating an incorrect temperature that is within the normal range of the sensor.
A. Connect Cat ET.
B. Use Cat ET to monitor the following temperature:
- Coolant temperature
Note: The temperature should rise steadily as the engine is warmed.
C. Ensure that the temperature is reasonable.
D. Reference the reading to another temperature indicator when possible. Refer to Testing
