COMPRESSOR(for 2TR-FE)

ADJUST COMPRESSOR OIL

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
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.
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.
