Refrigerant Leak Check
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
5. Refrigerant Leak Check
A: INSPECTION
1) At engine speed below 1500rpm, operate the A/
C system for approx. 10 minutes, and confirm that
the high-side pressure shows at least 690 kPa
(7.03 kg/cm2, 100 psi). Then stop the engine to
start the leak test.
2) Starting from the connection between high-pres-
sure pipe and evaporator, check the system for
leaks along the high-pressure side through the
compressor. The following items must be checked
thoroughly.
3) Check the joint and seam between pressure
switch (dual switch) and high-pressure pipe.
4) Check the connections between condenser and
pipes, and welded joints on the condenser.
The leak tester may detect the oil on the condenser
fins as a leak.
5) Check the joint between compressor and hoses.
6) Check the machined area of the compressor and
other joints on the compressor.
7) Check the compressor shaft seal at the area
near the center of compressor clutch pulley.
Some shaft seals show a slight amount of leakage,
about 3 g (0.1 oz) per year. This is not a problem.
8) Starting from the connection between low-pres-
sure pipe and evaporator, check the system for
leakage along the low-pressure side through the
compressor. The following items must be checked
thoroughly.
•Connection between 2 parts
•Connection between pipe and plate
•Connection between pipes
9) Visually check the rubber area of the flexible
hose for cracks.
Check the entire length of the flexible hose, espe-
cially the connection with the metal hose end.
CAUTION:
Carefully check the external surface of hoses
and tubes at approx. 25 mm (0.98 in) per sec-
ond.
10) Disconnect the drain hose from the heater
case, and check the hose end for at least 10 sec-
onds.
After the test is finished, reconnect the drain hose.
11) Turn the ignition key to the ON position, and
run the blower at high speed for approx. 1 minute.
Stop the blower to check the ventilation grill on the
instrument panel. While moving the tester closer to
the grill, run the blower for 1 or 2 seconds, then stop
it. Check the grill at that point for at least 10 sec-
onds.
12) Check the valve in the service port.
13) Visually check the rubber seal in the service
port cap.

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.

CAUTION:
•Subaru Select Monitor is required for reading DTC, performing diagnosis and reading current data.
•Remove foreign matter (dust, water, oil, etc.) from the body integrated unit connector during re-
moval and installation.
•For model with immobilizer, registration of immobilizer may be needed after the replacement of
controller etc. For detailed procedure, refer to the REGISTRATION MANUAL FOR IMMOBILIZER.
NOTE:
