Refrigerant Charging Procedure
6) Leave it at least 5 to 10 minutes after closing the
valves on low-/high-pressure sides, and then check
the low-pressure gauge reading for any changes.
When the gauge reading changes, this is a sign of
leakage. Check the pipe or hose connector points,
and repair if necessary. Repeat the procedure from
1) after repairing the faulty part.
7) If there are no leaks, further evacuate the sys-
tem 20 to 30 minutes.
8) Close all valves and stop the vacuum pump.
9) Following the can tap operation manual instruc-
tions, install it to refrigerant can.
10) Disconnect the vacuum pump from center
hose, and connect the hose to tap valve.
11) When a 13.6 kg (30 lb) refrigerant container is
used, measure the refrigerant amount in use using
a weighting scale before connecting to center hose.
12) Open the valve on HFC-134a source.13) Loosen the center hose connection on manifold
gauge (if applicable, press a purge valve on mani-
fold gauge) only for a couple of seconds to allow
the air in the center hose to escape by the refriger-
ant.
14) Make sure that the high-pressure valve of man-
ifold gauge is closed, and then open the low-pres-
sure side valve only to charge the refrigerant.
CAUTION:
Do not open the high-pressure valve. Be sure to
open the low-pressure valve.
15) Close the low-pressure valve when the low-
pressure gauge reading reaches 200 kPa (1,500
mmHg, 59.1 inHg).
16) Using a leak tester, check the system for refrig-
erant leaks.
17) After confirming that there are no leaks with the
leak test, charge the required amount of refrigerant.
18) If the HFC-134a source is empty, close the low-
pressure valve and then close the valve on can tap
before replacing the empty source. Restart charg-
ing operation after replacing the HFC-134a source
with a new one and purging.
19) Close the low-pressure valve if the charge rate
of refrigerant becomes worse.
20) Confirm that both the low-/high-pressure
valves are closed. Start the engine with A/C switch
OFF.
21) Quickly repeat A/C switch ON-OFF cycles a
few times to prevent initial compressor damage.

Refrigerant Leak Check
5. Refrigerant Leak Check
A: INSPECTION
1) Operate the A/C system for approx. 10 minutes,
and confirm that the high-pressure side shows at
least 690 kPa (7.03 kg/cm
2, 100 psi). Then stop the
engine to start the leak test.
2) Starting from the connection between the high-
pressure 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 the pressure
switch (triple pressure switch) and high-pressure
pipe.
4) Check the connections between the 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 the compressor and
hoses.
6) Check the machined area of 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 28 g (1.0 oz) per year. This is not a problem.
8) Starting from the connection between the low-
pressure 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 two parts
Connection between the pipe and plate
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 switch to ON, and run the
blower at high speed for 1 minute. Stop the blower
to check the ventilation grille on the instrument pan-
el. While moving the tester closer to the grille, run
the blower for 1 or 2 seconds, then stop it. Check
the grille at that point for at least 10 seconds.
12) Check the valve in the service port.
13) Visually check the rubber seal in the service
port cap.

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-

Engine Coolant
2. RELATIONSHIP OF SUBARU COOLANT
CONCENTRATION AND FREEZING TEM-
PERATURE
The concentration and safe operating temperature
of the SUBARU Genuine Coolant is shown in the
diagram. Measuring the temperature and specific
gravity of the coolant will provide this information.
[Example]
If the coolant temperature is 25°C (77°F) and its
specific gravity is 1.054, the concentration is 35%
(point A), the safe operating temperature is −14°C
(7°F) (point B), and the freezing temperature is −
20°C (−4°F) (point C).
3. PROCEDURE TO ADJUST THE CONC
ENTRATION OF THE COOLANT
To adjust the concentration of the engine coolant
according to temperature, find the proper fluid con-
centration in the above diagram and replace the
necessary amount of coolant with an undiluted so-
lution of SUBARU Genuine Coolant (concentration
50%).
The amount of coolant that should be replaced can
be determined using the diagram.
[Example]
Assume that the engine coolant concentration must
be increased from 25% to 40%. Find point A, where
the 25% line of the engine coolant concentration in-
tersects with the 40% curve of the necessary the
engine coolant concentration, and read the scale
on the vertical axis of the graph at height A. The
quantity of the engine coolant to be drained is 2.12
(2.2 US qt, 1.8 Imp qt). Drain 2.12 (2.2 US qt, 1.8
Imp qt) of coolant from the cooling system and add
2.12 (2.2 US qt, 1.8 Imp qt) of the undiluted solu-
tion of SUBARU Genuine Coolant.
If the engine coolant concentration of 50% is need-
ed, drain all the coolant and refill with the undiluted
solution only.

ATF
16.ATF
A: INSPECTION
CAUTION:
The level of ATF varies with fluid temperature.
Pay attention to the fluid temperature when
checking ATF level.
1) Raise the ATF temperature by driving a distance
of 5 to 10 km (3 to 6 miles). Otherwise, idle the en-
gine to raise ATF temperature to 70 — 80°C (158
— 176°F) on Subaru Select Monitor.
TION, Subaru Select Monitor.>
2) Make sure the vehicle is level.
3) After selecting all positions (P, R, N, D, 3, 2, 1),
set the select lever in “P” range. Measure the ATF
level with the engine idling for one or two minutes.
4) Make sure that ATF level is above the center of
upper and lower level.
NOTE:
When the transmission is hot, the level should be
above the center of upper and lower marks, and
when it is cold, the level should be found below the
center of these two marks.
5) If the ATF level is below the center between up-
per and lower marks, add the recommended ATF
until the ATF level is found above the center be-
tween upper and lower marks.
CAUTION:
Use care not to exceed the upper limit level.
Remember that the addition of ATF to the up-
per limit mark when the transmission is cold
will result in overfilling of ATF, causing a trans-
mission failure.
6) Check ATF level after raising ATF temperature
to 70 — 80°C (158 — 176°F) by running the vehicle
or by idling the engine again.7) Check the ATF for leaks.
Check for leaks in the transmission. If there are
leaks, it is necessary to repair or replace gasket, oil
seals, plugs or other parts.
B: REPLACEMENT
1. AUTOMATIC TRANSMISSION FLUID
1) Drain the ATF by removing drain plug.
NOTE:
Before starting work, cool off ATF well.
2) Replace the gasket with a new one, and then
tighten the specified torque.
Tightening torque:
25 N·m (2.5 kgf-m, 18.1 ft-lb)
3) Fill ATF up to the middle of the “COLD” side on
level gauge by using the gauge hole.
Recommended fluid:
