Section 28 (Heating / Air Conditioning System): Compressor: Installation

WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.

ADJUST COMPRESSOR OIL
1. When replacing the cooler compressor assembly with a new one, gradually discharge the inert gas (helium) from the service valve, and drain the following amount of oil from the vents indicated by the arrows in the illustration before installation

  The drain bolt and washer can be reused.
  
  Standard:
  
  (Oil capacity inside a new compressor and pulley: 130 + 15 cc (4.6 + 0.51 fl.oz.)) - (Remaining oil amount in the removed compressor and pulley) = (Oil amount to be removed when replacing the compressor)
  NOTE:
  - If a new compressor is installed without removing some oil, due to 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 refrigeration system failure.
  - If the volume of oil remaining in the removed compressor is too small, check for oil leakage.
  - Be sure to use ND-OIL 8 or equivalent for compressor oil.
INSTALL COMPRESSOR AND PULLEY
