COMPRESSOR AND PULLEY (for 1NZ-FE): Installation

1. When replacing the compressor with a new one, gradually discharge the refrigerant gas from the service valve. Then drain the following amount of oil from the new compressor before installation, so that the amount of oil contained in it is the same as that in the compressor to be replaced.

   HINT:

   New compressors are filled with sufficient oil for the whole cycle. Therefore, it is necessary to drain residual oil from the condenser and cooling unit.

   Standard: (The amount of oil inside a new compressor: 90 (+15) cc (3.0 (+0.51) fl.oz.)) - (The amount of oil remaining in the removed compressor) = The amount of oil to be removed when replacing the compressor 

   NOTE:

   • When checking the compressor oil level, observe the precautions for cooler removal/ installation.
   • If a new compressor is installed without removing the amount of oil remaining in the pipes of the vehicle, the amount of oil becomes too large. This prevents heat exchange in the refrigerant cycle and causes refrigeration failure.
   • If the amount of oil remaining in the removed compressor is too small, check for oil leakage.
   • Use ND-OIL8 compressor oil.

1. Remove the attached vinyl tape from the hose.
2. Apply sufficient compressor oil (ND-OIL8) to a new O-ring and the fitting surface of the compressor.

   Compressor oil: ND-OIL8 or the equivalent 

3. Install the O-ring onto the discharge hose.
4. Install the discharge hose onto the compressor with the bolt.
