Installation [08/2020 - ]: Procedure

1. When replacing the cooler compressor assembly and magnetic clutch assembly with a new one, gradually discharge the refrigerant gas from the service valve and drain the following amount of oil from the new cooler compressor assembly and magnetic clutch assembly before installation.

   Standard

   (Oil capacity inside the new cooler compressor assembly and magnetic clutch assembly: 120 + 15 cc (4.1 + 0.51 fl.oz.)) - (Remaining oil amount in the removed cooler compressor assembly and magnetic clutch assembly) = (Oil amount to be removed from the new cooler compressor assembly when replacing)

   NOTE:

   • When checking the compressor oil level, follow the A/C system precautions.
   • If a new cooler compressor assembly and magnetic clutch assembly is installed without removing some of the 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 cooler compressor assembly and magnetic clutch assembly is too small, check for oil leakage.
   • Be sure to use ND-OIL 8 or equivalent compressor oil.
