1. ADJUST COMPRESSOR OIL When replacing the compressor and magnetic clutch with a new one, gradually discharge the refrigerant gas from the service valve, and drain the following amount of oil from the new compressor and magnetic clutch before installation. Standard: (Oil capacity inside the new compressor and magnetic clutch: 130 +15 cc (4.6 + 0.51 fl.oz.)) - (Remaining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be removed from the new compressor when replacing) NOTE: When checking the compressor oil level, observe the A/C system's precautions. If a new compressor and magnetic clutch is installed without removing some oil remaining in the pipes of the vehicle, the oil amount will be too large. This prevents heat exchange in the refrigerant cycle and causes refrigerant failure. If the volume of oil remaining in the removed compressor and magnetic clutch is too small, check for oil leakage.
