Troubleshooting Test Steps
Values Results
6. Ambient Temperature
A. Check for a high ambient temperature.
Note: When outside temperatures are too high, there is insuf-
ficient temperature difference between the outside air and the
intake air.
Ambient
Temperature
Result: The ambient air temperature is high.
Repair: Operate the engine at reduced speed or reduced
power.
Result: The ambient air temperature is OK.
Proceed to Test Step 7.
7. Altitude
A. Check for operation at high altitude.
Note: The cooling capacity of the ATAAC is reduced as the
engine is operated at higher altitudes.
Altitude Result: The engine is being operated at high altitude.
Repair: Operate the engine at reduced speed or reduced
power.
Result: The engine is not being operated at high altitude.
Proceed to Test Step 8.
8. Running Condition
A. Check that the engine is not operating in the lug condition.
Note: When the load that is applied to the engine is too large,
the engine will run in the lug condition. When the engine is
running in the lug condition, engine rpm does not increase
with an increase of fuel. This lower engine rpm causes a re-
duction in coolant flow through the system.
Running
condition
Result: The engine is operating in the lug condition.
Repair: Reduce the load on the engine or, if possible, in-
crease the power rating of the engine.
Result: The engine is not operating in the lug condition.
