O? YES
NO
Is the inlet air temperature greater than 170°F? YES
NO
Recommended Test Procedure:
Install a temperature probe in the air compressor inlet hose or fitting as close to the
compressor as possible. Operate the vehicle such that the engine is at operating
temperature and the compressor is loaded/pumping. Record the compressor air inlet
temperature and note the ambient temperature. To obtain the maximum air inlet
temperature, add the difference between the recorded inlet temperature and the noted
ambient temperature to the maximum expected ambient temperature.
Was the restriction measured per the recommended procedure? YES
NO
If no, describe the procedure used: ___________________________________________
