HEATING / AIR CONDITIONING: COMPRESSOR (for 1AR-FE): ON-VEHICLE INSPECTION

ON-VEHICLE INSPECTION

1. INSPECT COMPRESSOR FOR METALLIC SOUND
(a) Check if there is abnormal metallic sound from the A/C compressor (compressor with pulley) when the A/C switch is on and the A/C compressor (compressor with pulley) operates.
If abnormal metallic sound is heard, replace the A/C compressor (compressor with pulley).
2. INSPECT REFRIGERANT PRESSURE
HINT: Refrigerant

3. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Using a gas leak detector, check for leakage of refrigerant.
If there is any leakage, replace the A/C compressor (compressor with pulley).
4. INSPECT A/C COMPRESSOR (COMPRESSOR PULLEY)
(a) Check operation of A/C compressor (compressor with pulley).
(1) Start the engine.
(2) Inspect the A/C compressor (compressor with pulley).
