Compressor Oil
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
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 on the A/C switch.
3) Turn the temperature control switch to MAX
COOL.
4) Put in RECIRC position.
5) Turn the blower control switch to HI. (For models
with rear coolers, also turn the rear cooler fan
switch to HI)
6) Leave in this condition for 10 minutes.
B: REPLACEMENT
NOTE:
•If a component has been replaced, add an ap-
propriate amount of compressor oil (same as the
amount of remaining oil in removed component).
•When replacing the compressor, the new com-
pressor will already have the specified amount of
oil in it. Install the new compressor after removing
the same amount of oil that is remaining in the com-
pressor removed.
