15. DISCONNECTION OF TIE ROD ENDUsing the special tool, disconnect the tie rod end from the
knuckle.Caution
1. Be sure to tie the cord of the special tool to the
nearby part.
2. Loose the nut but do not remove it.
16. DISCONNECTION OF LOWER ARM BALL JOINT
Using the special tool, disconnect the lower arm ball joint
from the knuckle.
Caution
1. Be sure to tie the cord of the special tool to the
nearby part.
2. Loose the nut but do not remove it.
17. DISCONNECTION OF DRIVE SHAFT
(1) Insert a pry bar between the transaxle case and the
drive shaft, and then pry the drive shaft from the
transaxle.
Caution1. Do not pull on the drive shaft; doing so will
damage the T.J.; be sure to use the pry bar.
2.Do not insert the pry bar so deep as to damagedthe oil seal.
(2) Keep the removed drive shaft as far away from the
transaxle case as possible, and secure (by using rope,
etc.) the T.J. to the body so that it does not fall.
20. REMOVAL OF SPECIAL BOLTS
(1) Remove the three special bolts connecting the con-
verter to the drive plate.
NOTETo remove the special bolts of torque converter, turn
engine crankshaft with a box wrench to bring one of
the bolts to the position appropriate for removal. After
removing the bolt, turn the crankshaft in the same
manner as above and remove all remaining bolts one
after another.
(2) After removing the special bolts, push the torque
converter toward transaxle so that it does not remain onthe engine side.

kPa(psi)2OPOO14(3) If the sight glass is clear and the magnetic clutch is
disengaged; the clutch is faulty or, the system is out of
refrigerant. Perform low pressure switch test to determine
condition. Check low pressure switch, and clutch coil for
electrical continuity.
(4) If the sight glass shows foam or bubbles, the system could
be low on charge. Occasional foam or bubbles are normal
when the ambient temperature is above
43°C (110°F) or
below
21°C (70°F).Adjust the engine speed to 1,500 rpm. Block the air-flow
thru the condenser to increase the compressor discharge
pressure to 1,422 to 1,520
kPa (206 to 220 psi). If sight
glass still shows bubbles or foam, system charge level is
low.The refrigerant system will not be low on charge unless
there is a leak. Find and repair the leak. If the leak can be
repaired without discharging the system an oil level check
is not necessary. Use the procedure for correcting low
refrigerant level found in the Refrigerant System Service
Procedure Section.DUAL PRESSURE SWITCH
The dual-pressure switch is a combination of the low-pressureswitch (for checking the quantity of refrigerant) and the,
high-pressure switch (for prevention of overheating); it is
installed on the tube, and, when the pressure becomes
approximately 210 kPa (30 psi) or lower, the compressor stops,thus preventing the compressor from being damaged by heat.
When the pressure reaches 2,700
kPa (384 psi) or higher, the
compressor stops, thus preventing overheating. There is
generally no necessity for inspection; if, however, an unusual
condition, such as non-operation of the compressor is encoun-tered, check by following the procedures below.
(1) Check for continuity of the dual-pressure switch.
NOTEIf the air temperature drops to
0°C (32°F) or lower during
cold weather, the air conditioner will not operate (no
continuity).(2) If there is an insufficient amount of refrigerant, check the
refrigerant amount by looking through the sight glass of thereceiver; supply refrigerant if necessary.
(Refer to P.24-21.)

(1) Clean sealing surface.
(2) Make sure O-ring does not have any scratches.
(3) Connect fitting, install fastener, and torque to amount
shown in the illustration.
The internal parts of the refrigeration system will remain in
a state of chemical stability as long as pure-moisture-free
R-12 and refrigerant oil is used. Abnormal amounts of dirt,
moisture of air can upset the chemical stability and cause
operational troubles or even serious damage if present in
more than minute quantities.
When it is necessary to open the refrigeration system, have
everything you will need to service the system ready so the
system will not be left open any longer than necessary. Capor plug all lines and fittings as soon as they are opened to
prevent the entrance of dirt and moisture. All lines and
components in parts stock should be capped or sealed until
they are ready to be used. All tools, including the refrigerant
dispensing manifold, the gauge set manifold and test hosesshould be kept clean and dry.
COMPRESSOR DRIVE BELT ADJUSTMENT N24FJAESatisfactory performance of the air conditioning system is
dependent upon drive belt condition and tension. If the proper
tensions are not maintained, belt slippage will greatly reduce airconditioning performance and drive belt life. To avoid such
adverse effects, the following service procedure should be
followed:
(1) Measure the deflection with a force of
IOON (22 Ibs.)applied to belt mid-point between tension pulley and
compressor pulley.
(2) Any belt that has operated for a minimum of one half-hour
is considered to be a “used” belt. Adjust air conditioning
drive belt at the time of new-car preparation.
(3) Check drive belt tension at regular service intervals and
adjust as needed.
Standard value:
When a new belt is installed<1.8L Engine>4-5 mm
(.16-.2 in.)
<2.0L DOHC Engine> 4.5-5 mm (.18-.2 in.)
When the used belt’s tension is adjusted

(.22-.24 in.)

24-24 HEATERS AND AIR CONDITIONING - Service Adjustment Procedures
COMPRESSOR NOISENUFIABWhen investigating an air conditioning related noise, you must
first know the conditions when the noise occurs. These
conditions are: weather, vehicle speed, in gear or neutral,
engine temperature or any other special conditions.
Noises that develop during air conditioning operation can oftenbe misleading. For example: what sounds like a failed front
bearing or connecting rod, may be caused by loose bolts, nuts,mounting brackets, or a loose clutch assembly. Verify acces-
sory drive belt tension (power steering, or alternator).
Improper accessory drive belt tension can cause a misleading
noise when the compressor is engaged and little or no noise
when the compressor is disengaged.
Drive belts are speed sensitive. That is, at different engine
speeds, and depending upon belt tension, belts can develop
unusual noises that are often mistaken for mechanical prob-
lems within the compressor.
Adjustment Procedures
(1) Select a quiet area for testing. Duplicate conditions as
much as possible. Switch compressor on and off several
times to clearly identify compressor noise.
To duplicate high ambient conditions (high head pressure),restrict air flow through condenser. Install manifold gauge
set to make sure discharge pressure doesn’t exceed 2,070
kPa (300 psi).
(2) Tighten all compressor mounting bolts, clutch mounting
bolt, and compressor drive belt. Check to assure clutch coilis tight (no rotation or wobble).
(3) Check refrigerant hoses for rubbing or interference that cancause unusual noises.
(4) Check refrigerant charge (See “Charging the System”).
(5) Recheck compressor noise as in Step 1.
(6) If noise still exists, loosen compressor mounting bolts and
retorque. Repeat Step 1.
(7) If noise continues, replace compressor and repeat Step 1.
