10. Wheel Balancing
1) Proper wheel balance may be lost if the tire is repaired
or if it wears. Check the tire for dynamic balance, and repair
as necessary.
2) To check for dynamic balance, use a dynamic balancer.
Drive in the balance weight on both the top and rear sides
of the rim.
3) Some types of balancer can cause damage to the
wheel. Use an appropriate balancer when adjusting the
wheel balance.
4) Use genuine balance weights.
Service limit: A
Weight for steel wheel;
1.6—2.0 mm (0.063—0.079 in)
Weight for aluminum wheel;
4.6—5.4 mm (0.181—0.213 in)
CAUTION:
55 g (1.94 oz) weight used with aluminum wheel is
not available.
Balance weights are available for use with any of 14-
to 15-inch wheels.
11. Installation of Wheel Assembly to
Vehicle
1) Attach the wheel to the hub by aligning the wheel bolt
hole with the hub bolt.
2) Temporarily attach the wheel nuts to the hub bolts. (In
the case of aluminum wheel, use SUBARU genuine wheel
nut for aluminum wheel.)
3) Manually tighten the nuts making sure the wheel hub
hole is aligned correctly to the guide portion of hub.
4) Tighten the wheel nuts in a diagonal selection to the
specified torque. Use a wheel nut wrench.
Wheel nut tightening torque:
88±10 N⋅m (9±1 kg-m, 65±7 ft-lb)
CAUTION:
Tighten the wheel nuts in two or three steps by
gradually increasing the torque and working
diagonally, until the specified torque is reached. For
drum brake models, excess tightening of wheel nuts
may cause wheels to “judder”.
Do not depress the wrench with a foot; Always use
both hands when tightening.
Make sure the bolt, nut and the nut seating surface
of the wheel are free from oils.
5) If a wheel is removed for replacement or for repair of a
puncture, retighten the wheel nuts to the specified torque
after running 1,000 km (600 miles).

1. Safety Precautions
1. HFC-134a AIR CONDITIONING SYSTEM
Component parts of the cooling system, refrigerant, com-
pressor oil, and other parts are not the same for the HFC-
134a system and the older CFC-12 system. Do not inter-
change parts or liquid.
Vehicles with HFC-134a air conditioning systems, use only
HFC-134a parts that are indicated on a label attached to
the vehicle. Before performing any maintenance, verify the
type of air conditioning system installed in the vehicle.
B4M0780
2. COMPRESSOR OIL
Do not use any compressor oil that is not specifically des-
ignated for the HFC-134a air conditioning system; only use
ZXL200PG. Also, do not use HFC-134a compressor oil in
the CFC-12 air conditioning system. If compression oils are
mixed, poor lubrication will result and the compressor itself
may be damaged.
Because HFC-134a compressor oil is very hygroscopic
(easily absorbs moisture), when parts of the air condition-
ing system are being removed, quickly install a blind plug
to prevent contact with the outside air. Also, always make
sure that the service container for compressor oil is tightly
closed except when in use. Store compressor oil in a tightly
closed steel container.

3. Tools and Equipment
The following section provides information about the tools
and equipment that will be necessary to properly service
the A/C system.
Since equipment may vary slightly depending on the
manufacturer, it is important to always read and follow the
manufacturer’s instructions.
CAUTION:
When working on vehicles with the HFC-134a system,
only use HFC-134a specified tools and parts. Do not
mix with CFC-12 tools and parts. If HFC-134a and
CFC-12 refrigerant or compressor oil is mixed, poor
lubrication will result and the compressor itself may be
destroyed.
In order to help prevent mixing HFC-134a and CFC-12
parts and liquid, the tool and screw type and the type
of service valves used are different. The gas leak
detectors for the HFC-134a and CFC-12 systems must
also not be interchanged.

system. A 7 to 40 N⋅m (0.7 to 4.1 kg-m, 5 to 30 ft-lb) torque
wrench with various crowfoot wrenches will be needed. Open
end or flare nut wrenches will be needed for back-up on the
tube and hose fittings.

8. Leak Testing
The following points should be kept in mind when conduct-
ing a refrigerant leak test.
1) The A/C system to be tested must have an adequate
refrigerant charge to begin with.
2) The area where the leak test is conducted must be free
of wind and drafts, with still air being the ideal condition.
3) The atmosphere where the leak test is conducted must
be free of refrigerant contamination.
4) Operate the A/C system for approx. 10 minutes, then
turn the engine off an begin the leak test.
5) Refrigerant gas is heavier than air, therefore always
hold the probe below the connection being tested.
6) When checking for a leak along a length of hose or
tube, the leak detector probe must be moved slowly,
approx. 25 mm (1 in) per second making sure probe does
not come in contact with the component being tested.
7) When checking for a leak at a certain point, the leak
detector probe must be held at that point for at least 5
seconds.
G4M0609
1. CHECK THE SYSTEM PRESSURE
With gauges connected to the A/C system, operate the A/C
and confirm that the high side pressure is above 690 kPa
(7.03 kg/cm
2, 100 psi). If not, evacuate and charge the
system before leak checking (refer to evacuation and
charging sections).
2. CLEAN CONNECTIONS BEFORE TESTING
Before testing, use a clean shop towel to wipe off refriger-
ant oil, dirt, or foreign material from all of the connections
and components to be tested.
NOTE:
Since refrigerant oil absorbs refrigerant, excess oil on or
near a connection may falsely signal a leak.
B4M0089
3. CALIBRATE LEAK DETECTOR
Refer to the manufacturer’s instructions for the particular
type of detector used and calibrate the instrument.
CAUTION:
Always make sure that the probe tip filter is clean and
free of contamination.

11. Compressor
Compressor is a swash plate type. When trouble occurs,
replace compressor as a single unit.
B4M0090
A: COMPRESSOR CLUTCH INSPECTION
Compressor clutch trouble is often caused by clutch slip-
page and noise. Check and take corrective measures, as
required.
1) Remove belt cover.
2) Check that clearance between drive plate and pulley
over the entire perimeter is within specifications.
Clearance:
0.3 — 0.6 mm (0.012 — 0.024 in)
B4M0091
3) Check that voltage applied to magnetic coil is at least
10.5 volts.
4) When noise is noted, check that it originates in either
compressor or pulley bearing.
B4M0760A
B: REMOVAL
1) Disconnect ground cable from battery.
2) Discharge refrigerant using refrigerant recovery system.

(1) Fully close low-pressure valve of manifold gauge.
(2) Connect low-pressure charging hose of manifold
gauge to low-pressure service valve.
(3) Open low-pressure manifold gauge valve slightly,
and slowly discharge refrigerant from system.
CAUTION:
Do not allow refrigerant to rush out. Otherwise, com-
pressor oil will be discharged along with refrigerant.
