COMPRESSOR AND PULLEY (for 2GR-FSE 4WD): Installation

  1. ADJUST COMPRESSOR OIL 
    1. When replacing the compressor with a new one, after gradually discharging the refrigerant gas from the service valve, drain the following volume of oil from the new compressor before installation.

      Standard: 

      (Oil capacity inside a new compressor: 130 + 15 cc (4.6 + 0.51 fl.oz.)) - (Remaining oil amount in the removed compressor) = (Oil amount to be removed from the new compressor when replacing it. 

      NOTE:
      • When checking the compressor oil level, observe the precautions in the cooler removal/installation.
      • If a new compressor is installed without removing some oil remaining in the pipes of the vehicle, the oil amount becomes excessive. 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.
      • Be sure to use ND-OIL 8 for compressor oil.
  2. INSTALL COMPRESSOR ASSEMBLY 
    1. Using an E8 "Torx" socket, install the compressor with the stud bolt.
