Troubleshooting Test Steps Values Results
1. Check for Low Coolant Level.
Coolant Level
Result: The engine coolant level is OK.
Proceed to Test Step 7.
Result : The engine coolant level is NOT OK.
Repair : Fill the coolant tank to the proper level if necessary.
Proceed to Test Step 2.
2. Check the Cooling System for Leaks.
Cooling system
Result : The cooling system is OK.
Proceed to Test Step 3.
Result: The cooling system is NOT OK.
Repair: Refer to Systems Operation/Testing and Adjusting, "Cooling System - Test" for the correct procedure. Repair any leaks immediately.
If the problem is not resolved, proceed to Test Step 3.
3. Check for Air in the Cooling System.
Cooling system
Result : The cooling system is OK.
Proceed to Test Step 4.
Result : There is air in the cooling system.
Repair : Refer to Systems Operation/Testing and Adjusting, "Testing the Cooling System" for the correct procedure.
If the problem is not resolved, proceed to Test Step 4.
4. Check for Leakage at the ARD Nozzle Heater O-rings (If Equipped).
Note : White exhaust smoke would be an indication of leakage past the ARD nozzle heater o-rings.
ARD nozzle heater o-rings
Result : The ARD nozzle heater o-rings are OK.
Proceed to Test Step 5.
Result : The ARD nozzle heater o-ring seals are NOT OK.
Repair : To check for leakage at the ARD nozzle heater o-rings, pressurize the cooling system and then remove the ARD head. Inspect the combustion can for signs of coolant. If the o-rings are leaking coolant, replace the ARD head.
If the problem is not resolved, proceed to Test Step 5.
5. Check for the Correct Mixture of Antifreeze and Water.
Antifreeze mixture
Result : The antifreeze and water mixture is OK.
Proceed to Test Step 6.
Result : The antifreeze and water mixture is NOT OK.
Repair : Refer to the Operation and Maintenance Manual.
If the problem is not resolved, proceed to Test Step 6.
6. Check for a Faulty Coolant Level Sensor
A. If an electrical problem with the coolant level sensor is suspected, refer to Troubleshooting, "Coolant Level - Test" for information that is related to troubleshooting an electrical problem with the coolant level sensor.
Coolant Level Sensor
Result: The coolant level sensor is not operating properly.
Repair: Replace the coolant level sensor.
