ON-VEHICLE SERVICE
HEATER, AIR CONDITIONER AND VENTILATION
55A-64
When a compressor is installed at the factory, it con-
tains 120 mL of compressor oil. While the A/C sys-
tem is in operation, the oil is carried through the
entire system by the refrigerant. Some of this oil will
be trapped and retained in various parts of the sys-
tem.
When the following system components are
changed, it is necessary to add oil to the system to
replace the oil being removed with the component.
Compressor oil: ZXL 100PG
Quantity
Evaporator: 60 mL
Condenser: 15 mL
Flexible suction hose: 10 mL
Receiver: 10 mL

2. Close the high and low-pressure valve of the
gauge manifold.
3. Connect the charging hose (blue) to the low-
pressure valve and connect the charging hose
(red) to the high-pressure valve of the gauge
manifold.
CAUTION
• To connect the quick joint, press section A
firmly against the service valve until a click is
heard.
• When connecting, run your hand along the
hose while pressing to ensure that there are
no bends in the hose.
4. Install the quick joint (for low-pressure) to the
charging hose (blue), and connect the quick joint
(for high-pressure) to the charging hose (red).
NOTE: The high-pressure service valve is on the
A/C pipe and the low-pressure service valve is on
the suction hose.
5. Connect the quick joint (for low-pressure) to the
low-pressure service valve and connect the quick
joint (for high-pressure) to the high-pressure
service valve.
6. Start the engine.
7. Set the A/C controls as follows:
• Mode selection dial: FACE position
• Temperature control dial: MAX COOL position
• Air selection: Recirculated air position
• Blower speed selection dial: 4 position
8. Adjust engine speed to 900 r/min with A/C clutch
engaged.
9. Engine should be warmed up with hood, doors
and windows opened.
