BRAKES - Service Adiustment Procedures5-45I

BLEEDINGN65FYAN
When the master cylinder is empty of brake fluid, bleed air
from the master cylinder by proceeding with procedures (1)
thru (6). (Because this master cylinder is not equipped with a
check valve.)
When brake fluid remains in the master cylinder, proceed with
step (6).
(1) -Disconnect the brake tube from the master cylinder.
(2) Two persons should conduct the air bleeding, one person
slowly depressing the brake pedal and holding the pedal
depressed.(3) In this condition, the other person should use a finger to
close the outlet part of the master cylinder, and then the
first person should release the brake pedal.
(4) Steps (2) and (3) should be repeated three or four times,
and then the master cylinder should be filled with brake
fluid to the specified level.
NOTE
The air is completely bled from the master cylinder by steps
(1) to (4).
(5) Connect the brake tube to the master cylinder.
(6) Start the engine; then, in the sequence shown in the
illustration, bleed the air from each wheel cylinder.
Specified brake fluid: MOPAR Brake Fluid/
Conforming to DOT3
Caution
1.Use the specified brake fluid. Avoid using a mixture
of the specified brake fluid and other fluid.2. If brake fluid is exposed to the air, it will absorb
moisture; as water is absorbed from the atmos-phere, the boiling point of the brake fluid will
decrease and the braking performance will be
seriously impaired. For this reason, use a hermeti-
cally sealed 1 lit.
(1.06 qt.) or 0.5 lit. (0.52 qt.) brake
fluid container.3. Firmly close the cap of the brake fluid container
after use.
4. For vehicles with the anti-lock braking system, besure to install a filter to the master cylinder
reservoir tank when supplying brake fluid.
ORDINARY AIR-BLEEDING PROCEDURES(1) Depress the brake pedal several times until resistance is
felt; then, with the pedal depressed, loosen the bleeder
screw
l/3 to l/2 turn and then tighten it before the fluid
pressure is all gone.
(2) Release the brake pedal. Repeat this procedure until there
are no more air bubbles in the brake fluid.

NO6OSAH
1. REMOVAL OF CLUTCH COVER ASSEMBLY/P.
CLUTCH DISCDiagonally loosen bolts which attach clutch cover to
flywheel. Back off bolts in succession, one or two turns at atime, to avoid bending cover flange.
Caution
DO NOT clean clutch disc or release bearing with
cleaning solvent.
INSPECTIONNlNGCAB
CLUTCH COVER ASSEMBLYl Check the diaphragm spring end for wear and uneven
height.
Replace
If wear is evident or height difference exceeds the
limit.Limit
: 0.5 mm (.02 in.)l
Check the pressure plate surface for wear, cracks and color
change.lCheck the strap plate rivets for looseness and replace the
clutch cover assembly if loose.
CLUTCH DISCl
Check the facing for loose rivets, uneven contact, deteriora-tion due to seizure,
adhesron of oil or grease and replace
the clutch disc if defective.
l
Measure the rivet sink and replace the clutch disc if it is outof specification.Limit
: 0.3 mm (.012 in.)l
Check for torsion spring play and damage and if defective,replace the clutch disc.
l Combine the clutch disc with the input shaft and check
sliding condition and check for play in the rotating direction.If it does not slide smoothly, check after cleaning and
reassembling. If the play IS excessive, replace the clutch
drsc and/or the input shaft.
CLUTCH RELEASE BEARING
Caution
The release bearing is packed with grease, so don’t use
cleaning oil, etc. to clean it.l Check for
beanng heat damage, other damage, abnormal
noise and/or improper rotation. Also check whether or not
there IS wear at the point of contact with the diaphragm
spring.lIf there is abnormal wear at the pornt of contact with the
release fork, replace the bearing.
RELEASE FORKlIf there is abnormal wear at the
pornt of contact with the
bearing, replace the release fork.

COOLING - Troubleshooting7A7
OPERATION
1. When the output of the air conditioner*--control unit is “LO” (OV)(when the
compressor magnet clutch isdeenergized)
l When the ignition switch is at “ON” , and if
engine coolant temperature rises to
85°C
(185”F), the thermosensor contacts close,
causing current to flow through the radiator
fan motor relay (coil), thermosensor and
ground, causing the radiator fan motor relay
contacts to close.
l Current flows through the radiator fan motor
relay contacts, radiator fan motor and ground,causing the radiator fan motor to rotate.
2. When the output of the air conditioner
control unit is “HI” (approx. 12V)(when the
compressor magnet clutch is
energized)l If the therm0 sensor is “ON” when the
engine coolant temperature exceeds
85°C
(185°F). the condenser fan motor control relay
is also “ON”, thus the condenser fan as well
as the radiator fan start rotating at a high
speed.
TROUBLESHOOTING HINTS
1. Neither the radiator fan nor condenser fanrotate at
all.l Check sub fusible link
No.3.
2. Only the condenser fan does not operate.l Check dedicated fuse
No.5.
3. The radiator fan and condenser fan do notoperate
in the low speed mode, but operateotherwise.
(1)The A/C compressor magnet clutch does not
enter the “ON” state.
l Check whether the output of the air con-
ditioner control unit is available.
NOTEFor troubleshooting of the air conditioner
control unit, refer to GROUP 24.
(2)The A/C compressor magnet clutch enters
the “ON” state.

INSPECTIONNo7OcAMl Check for foreign material between radiator fins.
l Check the radiator fins for bent, or damage.
l Check the radiator for corrosion, damage rust or scale.
lCheck the radiator hoses for cracks, damage or deteriora-
tion.l Check the reserve tank for damage.
lCheck the automatic transaxle oil cooler hoses for cracking,damage or deterioration.
RADIATOR FAN MOTOR INSPECTION(1) Check to be sure that the radiator fan rotates when batten/
voltage is applied between terminals (as shown in the
figure).
(2) Check to see that abnormal noises are not produced, whilemotor is turning.
THERM0 SENSOR INSPECTIONCheck for continuity with the therm0 sensor in hot water.
NOTEImmerse therm0 sensor in hot water up to mounting thread to
check for continuity.
