Compressor Oil
6. Compressor Oil
A: OPERATION
NOTE:
Before making repairs, conduct the oil return oper-
ation to return the compressor oil in circulation with
the refrigerant to the compressor.
1) Increase the engine speed to 1,500 rpm.
2) Turn ON the A/C switch.
3) Turn the temperature control dial to MAX COOL.
4) Set the air inlet select switch to RECIRC posi-
tion.
5) Turn the fan dial to HI.
6) Leave in this condition for 10 minutes.
B: REPLACEMENT
NOTE:
If a component is replaced, add an appropriate
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.
