6. Compressor Oil
A: PROCEDURE
NOTE:
Before making repairs, perform the oil return oper-
ation to return the compressor oil in circulation with
the refrigerant to the compressor.
1) Increase the engine to 1,500 rpm.
2) Turn the A/C switch to ON.
3) Turn the temperature control switch to MAX
COOL.
4) Put in RECIRC position.
5) Turn the blower control switch to HI.
6) Leave in this condition for 10 minutes.
B: REPLACEMENT
NOTE:
• After replacing the component, add an appropri-
ate amount of compressor oil.
• When replacing the compressor, the new com-
pressor will already have the specified amount of
oil in it. Adjust the amount of oil so that the amount
of oil in the new compressor is the same as the
amount in the removed compressor. (Measure the
amount of oil remaining in the removed compressor
accurately. Empty the oil from the new compressor
in a clean container, then refill the new compressor
with the same amount of oil that was in the re-
moved compressor.)
