0A-4 GENERAL INFORMATION
SERVICING AND HANDLING
WARNING:
Many of service procedures require disconnection of ªAIR
BAGº fuse and all air bag (inflator) module(s) from initiator
circuit to avoid an accidental deployment.
Driver and Passenger Air Bag (Inflator) Modules

For handling and storage of a live air bag (inflator) module,
select a place where the ambient temperature below 65
C
(150
F), without high humidity and away from electric
noise.

When carrying a live air bag (inflator) module, make sure
the bag opening is pointed away from you. In case of an
accidental deployment, the bag will then deploy with mini-
mal chance of injury. Never carry the air bag (inflator)
module by the wires or connector on the underside of the
module. When placing a live air bag (inflator) module on
a bench or other surface, always face the bag up, away
from the surface. As the live passenger air bag (inflator)
module must be placed with its bag (trim cover) facing up,
place it on the workbench with a slit or use the workbench
vise to hold it securely at its lower mounting bracket. This
is necessary so that a free space is provided to allow the
air bag to expand in the unlikely event of accidental de-
ployment. Otherwise, personal injury may result.

Never dispose of live (undeployed) air bag (inflator) mod-
ules (driver and passenger). If disposal is necessary, be
sure to deploy them according to deployment procedures
described in SECTION 10B before disposal.

The air bag (inflator) module immediately after deploy-
ment is very hot. Wait for at least half an hour to cool it off
before proceeding the work.

After an air bag (inflator) module has been deployed, the
surface of the air bag may contain a powdery residue. This
powder consists primarily of cornstarch (used to lubri-
cate the bag as it inflates) and by-products of the chemical
reaction. As with many service procedures, gloves and
safety glasses should be worn.

MAINTENANCE AND LUBRICATION 0B-19
11) Check coil spring, upper rod, lower rod and lateral rod for de-
formation and damage.
12) Check upper rod, lower rod and lateral rod bushings and bump
stopper for wear, damage and deterioration.
13) Check other suspension parts for damage, loose or missing
parts; also for parts showing signs of wear or lack of lubrication.
Replace any parts found defective in steps 1) to 13).
ITEM 6-9
Propeller Shafts and Drive Shafts Inspection
1) Check universal joint and spline of propeller shaft for rattle. If
rattle is found, replace defective part with a new one.
2) Check propeller shaft (front & rear) flange yoke bolts for tight-
ness, and retighten them as necessary.
Refer to Section 4B for tightening torque.
3) Check drive axle boots (wheel side and differential side) for
leaks, detachment, tear or other damage.
Replace boot as necessary.

GENERAL DESCRIPTION
The air conditioning system of this model differs by the country of origin (the production plant.).
One is Japan (IWATA) produced, other one is Canada (CAMI) produced.
For the details of the identification, please refer to IDENTIFICATION INFORMATION of Section 0A in this manual.
The compressor used of Japan (IWATA) produced vehicle is made of SEIKO SEIKI and the compressor used of
Canada (CAMI) produced vehicle is made of DENSO.
IDENTIFICATION OF REFRIGERATING
SYSTEM
Whether the A / C equipped with the vehicle being serviced uses re-
frigerant R-134a or R-12 is indicated on the LABEL installed the
compressor.
Also, it can be identified by the shape of the service (charge) valve.
The compressor manufacturer, it can be identified by the LABEL on
compressor body.

DIAGNOSIS OF ABNORMAL NOISE
There are various types of noise, ranging from those produced in the engine compartment to those from the pas-
senger compartment, also from rumbling noises to whistling noises.
ABNORMAL NOISE FROM COMPRESSOR
ConditionPossible CauseCorrection

During compressor operation, a
rumbling noise is heard
proportional to engine
revolutions.
Inadequate clearance in piston
area (piston or swash-plate).
Repair or replace compressor as
necessary.

A loud noise is heard at a certain
rpm, disproportionately to engine
revolution.
Loose or faulty V-belt.

Loose mounting bolts.
Adjust V-belt tension, or
replace belt.

Retighten mounting bolts.

A loud rattle is heard at low
engine rpm.
Loose compressor center bolt.
Retighten center bolt.

Replace compressor if it was
operated in this condition for a
long time.
ABNORMAL NOISE FROM MAGNETIC CLUTCH
ConditionPossible CauseCorrection

A rumbling noise is heard when
compressor is not operating.
Worn or damaged bearings.
Replace bearings.

A chattering noise is heard when
compressor is engaged.
Faulty clutch gap (excessive).

Worn clutch friction surface.

Compressor oil leaked from shaft
seal, contaminating the friction
surface.
Adjust clutch gap.

Replace clutch.

Replace compressor shaft oil
seal.
ABNORMAL NOISE FROM TUBING
ConditionPossible CauseCorrection

A droning noise is heard inside
vehicle, but not particularly
noticeable in engine
compartment.
Faulty tubing clamps.

Resonance caused by pulsation
from variations in refrigerant
pressure.
Reposition clamps or increase
the number of clamps.

Attach a silencer to tubing, or
modify its position and length.
ABNORMAL NOISE FROM CONDENSER
ConditionPossible CauseCorrection

Considerable vibration in
condenser.
Resonance from condenser
mounting stay and body.
Firmly insert a silencer between
condenser mounting stay and
body.

ABNORMAL NOISE FROM CRANKSHAFT PULLEY
ConditionPossible CauseCorrection

A large rattling noise is heard at
idle or sudden acceleration.
Loosen pulley mounting bolt.

Worn or broken bearings.
Retighten bolt.

Replace bearings.
ABNORMAL NOISE FROM TENSION PULLEY
ConditionPossible CauseCorrection

Clattering noise is heard from
pulley.

Pulley cranks upon contact.
Worn or damaged bearings.

Cracked or loose bracket.
Replace bearings.

Replace or retighten bracket.
ABNORMAL NOISE FROM EVAPORATOR
ConditionPossible CauseCorrection

Whistling sound is heard from
evaporator.
Depending on the combination of
the interior / exterior
temperatures, engine rpm and
refrigerant pressure, the
refrigerant flowing out of the
expansion valve may, under
certain conditions, make a
whistling sound.
At times, slightly decreasing
refrigerant volume may stop this
noise.

Inspect expansion valve and
replace if faulty.
ABNORMAL NOISE FROM BLOWER MOTOR
ConditionPossible CauseCorrection

Blower motor emits a chirping
sound in proportion to its speed of
rotation.

Fluttering noise or large droning
noise is heard from blower motor.
Worn or damaged motor brushes
or commutator.

Leaves or other debris
introduced from fresh air inlet to
blower motor.
Repair or replace blower motor.

Remove debris and make sure
that the screen at fresh air inlet is
intact.
