Chevrolet Trax: Air conditioning compressor oil balancing
Draining Procedure
NOTE: Drain and measure as much of the refrigerant oil as possible
from the rear
head ports of the removed air conditioning compressor.
- Before draining oil, position the compressor vertically, (clutch facing
upwards) and let the air
conditioning compressor sit for 1 minute.
- Position the air conditioning compressor horizontally with the ports
facing downward, rotate the clutch
and shake the air conditioning compressor in order to remove as much oil
from the air conditioning
compressor as possible.
- Drain the oil from both the suction and discharge ports of the removed
air conditioning compressor into a
clean, graduated container. Rotate the air conditioning compressor shaft to
assist in draining the air
conditioning compressor.

- Measure and record the amount of oil drained from the removed air
conditioning compressor. This
measurement will be used during installation of the replacement air
conditioning compressor. Inspect oil
drained from removed air conditioning compressor. Refer to Air Conditioning
Compressor Oil
Diagnosis.
- Properly discard the used refrigerant oil.
Balancing Procedure
NOTE: The refrigerant oil in the air conditioning system must be
balanced during
air conditioning compressor replacement.
- Before installing the air conditioning compressor, the refrigerant oil
will have to be fully drained.
