Oil check
The compressor oil must be checked and
adjusted as follows when replace compressor or
performance system service:
1. Perform the oil return operation (p.11).
2. Remove the old compressor from the vehicle.
3. Drain the oil through both suction and
discharge ports. To drain maximum amount of
oil, with both ports facing down, slowly
position
the
compressor
at
different
orientations, then rotate the compressor
armature plate 3 ~ 5 turns. Repeat 2 ~ 3 times.
4. Check the oil for contamination.
5. Adjust the oil amount of the new replacement
compressor per chart below. In case additional
oil need to be added, fill oil through the suction
port (see table below).
CAUTION!
All of the oil cannot be removed when
draining the compressor as some remains as
an oil film on the inside of the compressor
and the system components. Therefore, refer
to the table at left when recharging the
compressor with oil. Excess oil adversely
affects the cooling capacity and the
