0A-20 GENERAL INFORMATION
In raising front or rear vehicle end off the floor by jacking, be sure
to put the jack against the center portion of the front suspension
frame or rear axle housing.
WARNING:
Never apply jack against suspension parts (i.e., stabilizer,
etc.) or vehicle floor, or it may get deformed.
If the vehicle to be jacked up only at the front or rear end,
be sure to block the wheels on ground in order to ensure
safety.
After the vehicle is jacked up, be sure to support it on
stands. It is extremely dangerous to do any work on the
vehicle raised on jack alone.
To perform service with either front or rear vehicle end jacked up,
be sure to place safety stands under chassis frame so that body is
securely supported. And then check to ensure that chassis frame
does not slide on safety stands and the vehicle is held stable for
safety's sake.

AIR CONDITIONING (OPTIONAL) 1B-25
EVACUATING
EVACUATING PROCEDURE
CAUTION:
Do not evacuate before recovering refrigerant in system.
NOTE:
Whenever opened (exposed to atmospheric air), air condition-
ing system must be evacuated by using a vacuum pump. The
A / C system should be attached with a manifold gauge set, and
should be evacuated for approx. 15 minutes.
1) Connect high charging hose (1) and low charging hose (2) of
manifold gauge set (3) respectively as follows:
High Charging Hose (1)
High pressure charging valve (4)
on Discharge Hose
Low Charging Hose (2)i
Low pressure charging valve (5)
on Suction Pipe
2) Attach center charging hose (6) of manifold gauge set (3) to vac-
uum pump (7).
3) Operate vacuum pump (7), and then open discharge-side valve
(9) (Hi) of manifold gauge set (3).
If there is no blockage in the system, there will be an indication
on high pressure gauge (10).
When this occurs, open the other-side valve (8) (Lo) of the set.
4) Approx. 10 minutes later, low pressure gauge (11) should show
a vacuum lower than ± 760 mmHg providing no leakage exists.
NOTE:
If the system does not show a vacuum below ± 760 mmHg,
close both valves, stop vacuum pump and watch move-
ment of low pressure gauge.
Increase in the gauge reading suggests existence of leak-
age. In this case, repair the system before continuing its
evacuation.
If the gauge shows a stable reading (suggesting no leak-
age), continue evacuation.
5) Evacuation should be carried out for a total of at least 15 minutes.
6) Continue evacuation until low pressure gauge indicates a vacu-
um less than ± 760 mmHg, and then close both valves (8), (9).
7) Stop vacuum pump (7). Disconnect center charging hose (6) from
pump inlet. Now, the system is ready for charging refrigerant.
CHECKING SYSTEM FOR PRESSURE LEAKS
After completing the evacuation, close manifold gauge high pres-
sure valve (HI) and low-pressure valve (LO) and wait 10 minutes.
Verify that low-pressure gauge reading has not changed.
CAUTION:
If the gauge reading moves closer to ª0º, there is a leak
somewhere. Inspect the tubing connections, make neces-
sary corrections, and evacuate system once again, making
sure that there are no leaks.

AIR CONDITIONING (OPTIONAL) 1B-33
A / C CONDENSER ASSEMBLY
INSPECTION
Check
a) condenser fins for blockage
b) condenser fittings for leakage
c) condenser fins for damage
Clogged condenser fins should be washed with water, and should
be dried with compressed air.
CAUTION:
Be careful not to damage condenser fins. If condenser fin is
bent, straighten it by using a screwdriver or pair of pliers. If
any leakage is found from fitting or tube, repair or replace
condenser.
REMOVAL
1) Disconnect negative (±) cable at battery.
2) Recover refrigerant by using recovery and recycling equipment.
Be sure to follow the instruction manual for the equipment.
The amount of compressor oil removed must be measured and
the same amount added to the system.
3) Remove front bumper assembly and remove lower stay (1) if
equipped (Refer to Section 9 ªBODY SERVICEº).
4) Disconnect compressor discharge hose (1) from condenser in-
let fittings.
CAUTION:
As soon as above hose and pipe are disconnected, cap
opened fittings so that moisture and dust do not enter
condenser.

AIR CONDITIONING (OPTIONAL) 1B-41
INSPECTION
1) Check evaporator fins for blockage. If found clogged, use com-
pressed air to clean the fins.
CAUTION:
Do not use water for cleaning of evaporator.
Be careful not to damage evaporator fins. If evaporator
fin is bent, straighten it by using a screwdriver or pair of
pliers. If any leakage is found from fitting or tube, repair
or replace evaporator.
2) Check inlet and outlet fittings for crack or scratch. Repair them
as required.
REASSEMBLY and INSTALLATION
1) Reverse removal and disassembly sequence to install cooling
unit, noting the following points.
Install uniformly the evaporator packing to dash panel hole for
expansion valve.
Adjust fresh air control cable, refer to ªHEATER CONTROL
LEVER ASSEMBLYº in Section 1A.
2) Enable air bag system. Refer to ªEnabling Air Bag Systemº in
Section 10B.
3) Evacuate and charge system. Refer to ªEVACUATINGº and
ªCHARGINGº in this section.
NOTE:
When the thermistor removed, it should be reinstalled in
original position.
If cooling unit or evaporator is replaced, pour 25 cc of refrig-
erating oil to compressor suction-side.

TIRE DIAGNOSIS
IRREGULAR AND / OR PREMATURE WEAR
Irregular and premature wear has many possible causes. Some of
them are: incorrect inflation pressures, lack of tire rotation, driving
habits, improper alignment.
If the following conditions are noted, rotation is in order:
1. Front tire wear is different from rear.
2. Uneven wear exists across the tread of any tire.
3. Left front and right front tire wear is unequal.
4. Left rear and right rear tire wear is unequal.
5. There is cupping, flat spotting, etc.
A wheel alignment check is in order if the following conditions are
noted:
1. Left front and right front tire wear is unequal.
2. Wear is uneven across the tread of any front tire.
3. Front tire treads have scuffed appearance with ªfeatherº edges
on one side of tread ribs or blocks.
WEAR INDICATOR
The original equipment tires have built-in tread wear indicators to
show when tires need replacement. These indicators will appear as
12 mm (0.47 in.) wide bands when the tire tread depth becomes 1.6
mm (0.063 in.). When the indicators appear in 3 or more grooves
at 6 locations, tire replacement is recommended.
RADIAL TIRE WADDLE
Waddle is side to side movement at the front and / or rear of the ve-
hicle. It is caused by the steel belt not being straight within the tire.
It is most noticeable at low speed, 8 to 48 km / h (5 to 30 mph). It is
possible to road test a vehicle and tell on which end of the vehicle
the faulty tire is located. If the waddle tire is on the rear, the rear end
of the vehicle will shake from side to side or ªwaddleº. From the driv-
er's seat it feels as though someone is pushing on the side of the
vehicle. If the faulty tire is on the front, the waddle is more visual.
The front sheet metal appears to be moving back and forth and the
driver feels as though he is at the pivot point in the vehicle.
Waddle can be quickly diagnosed by using a Tire Problem Detector
(TPD) and following the equipment manufacturer's recommenda-
tions.
If a TPD is not available, the more time consuming method of sub-
stituting known good tire / wheel assemblies on the problem vehicle
can be used as follows:

STALL TEST
This test is to check overall performance of automatic transmission
and engine by measuring stall speed at ªDº and ªRº ranges. Be sure
to perform this test only when transmission fluid is at normal operat-
ing temperature and its level is between FULL and LOW marks.
CAUTION:
Do not run engine at stall more than 5 seconds continu-
ously, for fluid temperature may rise excessively high.
After performing stall test, be sure to leave engine running
at idle for longer than 30 seconds before another stall test.
1) Apply parking brake and block wheels.
2) Install tachometer.
3) Start engine with select lever shifted to ªPº.
4) Depress brake pedal fully.
5) Shift select lever to ªDº and depress accelerator pedal fully while
watching tachometer. Read engine rpm quickly when it has be-
come constant (stall speed).
6) Release accelerator pedal immediately after stall speed is
checked.
7) In the same way, check stall speed in ªRº range.
