Installation

HEATING / AIR CONDITIONING: COMPRESSOR (for 2TR-FE): INSTALLATION

1. ADJUST COMPRESSOR OIL

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

Standard:

(Oil capacity inside the new compressor and magnet clutch: 180 + 15 cc (6.08 + 0.51 fl.oz.)) - (Remaining oil amount in the removed compressor and magnet clutch) = (Oil amount to be removed from the new compressor)

NOTICE:
* When checking the compressor oil level, follow the A/C system precautions.
* Since compressor oil remains in the pipes of the vehicle, if a new compressor is installed without removing some oil from the compressor, the oil amount becomes excessive. Excessive oil prevents heat exchange in the refrigerant cycle and causes refrigeration system failure.
* If the volume of oil remaining in the removed compressor and magnet clutch is small, check for oil leakage.
* Be sure to use ND-OIL 8 or equivalent compressor oil.
