0B-24 MAINTENANCE AND LUBRICATION
FINAL INSPECTION
Seats
Check that seat slides smoothly and locks securely at
any position. Also check that reclining mechanism of
front seat back allows it to be locked at any angle.
Seat Belt
Inspect belt system including webbing, buckles, latch
plates, retractors and anchors for damage or wear.
If ªREPLACE BELTº label on front seat belt is visible,
replace belt.
Check that seat belt is securely locked.
Battery Electrolyte Level Check
Check that the electrolyte level of all battery cells is
between the upper and lower level lines on the case.
If battery is equipped with built-in indicator, check bat-
tery condition by the indicator.
Accelerator Pedal Operation
Check that pedal operates smoothly without getting
caught or interfered by and other part.
Engine Start
Check engine start for readiness.
On automatic transmission vehicles, try to start the
engine in each select lever position. The starting mo-
tor should crank only in ªPº (Park) or ªNº (Neutral).
On manual transmission vehicles, place the shift le-
ver in ªNeutral,º depress clutch pedal fully and try to
start.
Exhaust System Check
Check for leakage, cracks or loose supports.
Clutch (For Manual transmission)
Check for the following:

Clutch is completely released when depressing
clutch pedal.

No slipping clutch occurs when releasing pedal and
accelerating.

Clutch itself is free from any abnormal condition.
Gearshift or Select Lever (Transmission)
Check gear shift or select lever for smooth shifting to
all positions and for good performance of transmis-
sion in any position.
With automatic transmission equipped vehicle, also
check that shift indicator indicates properly according
to which position select lever is shifted to.
With automatic transmission equipped vehicle, make
sure that vehicle is at complete stop when shifting se-
lect lever to ªPº range position and release all brakes.
Brake
[Foot brake]
Check the following:

that brake pedal has proper travel,

that brake works properly,

that it is free from noise,

that braking force is applied equally on all wheels,

and that brake do not drag.
[Parking brake]
Check that lever has proper travel.
WARNING:
With vehicle parked on a fairly steep slope,
make sure nothing is in the way downhill to
avoid any personal injury or property damage.
Be prepared to apply regular brake quickly
even if vehicle should start to move.
Check to ensure that parking brake is fully effective
when the vehicle is stopped on the safe slope and
brake lever is pulled all the way.
WARNING:
When carrying out road tests, select a safe
place where no man or no running vehicle is
seen so as to prevent any accident.
WARNING:
Before performing the following check, be
sure to have enough room around the vehicle.
Then, firmly apply both the parking brake and
the regular brakes. Do not use the accelerator
pedal. If the engine starts, be ready to turn off
the ignition promptly. Take these precautions
because the vehicle could move without warn-
ing and possibly cause personal injury or
property damage.

Check that engine responds readily at all speeds.

Check that engine is free from abnormal noise and
abnormal vibration.
Body, Wheels and Power Transmitting System
Check that body, wheels and power transmitting sys-
tem are free from abnormal noise and abnormal
vibration or any other abnormal condition.

Check that speedometer, odometer, fuel meter, tem-
perature gauge, etc. are operating accurately.
Lights

AIR CONDITIONING (OPTIONAL) 1B-9
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.

9) Check for each pressure of low side and high side if it is within
shaded range of graph.
If each gauge reading is out of specified pressure, correct de-
fective part referring to following Test Diagnosis table.
Example:
Gauges should read as follows when ambient
temperature is 30
C.
Pressure on high pressure
gauge (HI):1400 ± 1750 kPa
14.0 ± 17.5 kg / cm
2
Pressure on high pressure
gauge (LO):230 ± 350 kPa
2.3 ± 3.5 kg / cm
2
NOTE:
Pressure registered on gauge varies with ambient temper-
ature. Therefore, use left graphs when determining if pres-
sures are normal or not.
10) Check inlet port temperature-to-outlet port temperature rela-
tionship using graph.
For example, if evaporator inlet port temperature is 25
C
(77
F) and center duct air outlet temperature is 8
C (46.4
F),
their crossing point is within acceptable range as shown in
graph.
11) If crossing point is out of acceptable range, diagnose trouble
referring to following Performance Diagnosis table.

REFRIGERANT RECOVERY, EVACUATION AND CHARGING
WARNING:

Your eyes should not be exposed to refrigerant (liquid).
Any liquid Refrigerant-134a escaping by accident shows a temperature as low as approx. ± 6C
(42.8F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a seri-
ous injury. To protect your eyes against such accident, it is necessary to always wear goggles. Should
it occur that HFC-134a (R-134a) strikes your eye(s), consult a doctor immediately.
± DO NOT USE YOUR HAND TO RUB THE AFFECTED EYE(S). INSTEAD, use quantities of fresh cold
water to splash it over the affected area to gradually raise temperature of such area above freezing
point.
± Obtain proper treatment as soon as possible from a doctor or eye specialist.

Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.

Refrigerant must not be handled near where welding or steam cleaning is performed.

Refrigerant should be kept at a cold and dark place. It should never be stored where a high tempera-
ture is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle (including
trunk room).

Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazardous
to health.

16 mm pipe: 33 N
.m (3.3 kg-m, 23.8 lb-ft)

Route drain hose so that drained water does not make any contact to vehicle components.
HANDLING REFRIGERANT HFC-134a (R-134a)

When handling refrigerant, always wear goggles to protect your eyes.

Avoid you direct contact to liquid refrigerant.

Do not heat refrigerant container higher than 40C (104F).

Do not discharge refrigerant into atmosphere.

Do not allow liquid refrigerant to touch bright metals. Refrigerant combined with moisture is corrosive and will
tarnish surfaces of bright metals including chrome.

After recovering refrigerant from system, the amount of compressor oil removed must be measured and the same
amount added to the system.
REFRIGERANT RECOVERY
When discharging refrigerant out of A / C system, always recover it by using refrigerant recovery and recycling
equipment. Discharging refrigerant HFC-134a (R-134a) into atmosphere would cause adverse effect to environ-
ments.
NOTE:
When handling recovery and recycling equipment, be sure to follow the instruction manual for the equip-
ment.
REFRIGERANT CHARGE
Charge a proper amount of refrigerant to A / C system according to charging procedure described in recovery, evac-
uation and charging.
CAUTION:
Do not perform an additional refrigerant charging to A / C system. This cause it to overcharge.
