COMPRESSOR(for 1GR-FE) INSTALLATION

PROCEDURE


  1. ADJUST COMPRESSOR OIL


    1. When replacing the cooler compressor 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 before installation.

      Standard
      for Single Air Conditioning System:
      (The amount of oil inside a new cooler compressor: 120 to 135 cc (4.1 to 4.6 fl. oz.)) - (The amount of oil remaining in the removed cooler compressor) = (The amount of oil to be removed when replacing the compressor)
      Standard
      for Dual Air Conditioning System:
      (The amount of oil inside a new cooler compressor: 180 to 195 cc (6.1 to 6.6 fl. oz.)) - (The amount of oil remaining in the removed cooler compressor) = (The amount of oil to be removed when replacing the compressor)

      Note


      • When checking the compressor oil level, follow the A/C system precautions.

      • If a new cooler compressor 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 cooler compressor is too small, check for oil leakage.

      • Be sure to use ND-OIL 8 or equivalent for compressor oil.

  2. INSTALL COOLER COMPRESSOR ASSEMBLY
