COMPRESSOR(for 2WW) INSTALLATION

PROCEDURE

  1. INSPECT COMPRESSOR OIL

    1. E332767

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

      Standard

      (Oil capacity inside the new compressor assembly with pulley: 70 to 85 cc (2.37 to 2.87 fl.oz)) - (Remaining oil amount in the removed compressor assembly with pulley) = (Oil amount to be removed from the new compressor)

      Note:

      • If a new compressor assembly with pulley is installed without removing some oil, there will be too much oil in the system due to the oil remaining in the pipes of the vehicle. Excessive oil in the system prevents heat exchange in the refrigeration cycle and causes ineffective cooling.

      • If the amount of oil remaining in the old compressor assembly with pulley is too small, check the air conditioning system for oil leaks.

      • for HFC-134a(R134a): Make sure to use ND-OIL 8 or equivalent compressor oil.

      • for HFO-1234yf(R1234yf): Make sure to use ND-OIL 12 or equivalent compressor oil.
