GENERAL INFORMATION 0A-9

When disconnecting vacuum hoses, attach a tag describing
the correct installation positions so that the hoses can be re-
installed correctly.

After servicing fuel, oil, coolant, vacuum, exhaust or brake
systems, check all lines related to the system for leaks.

For vehicles equipped with fuel injection systems, never dis-
connect the fuel line between the fuel pump and injector
without first releasing the fuel pressure, or fuel can be
sprayed out under pressure.
PRECAUTIONS FOR CATALYTIC CONVERTER
For vehicles equipped with a catalytic converter, use only un-
leaded gasoline and be careful not to let a large amount of un-
burned gasoline enter the converter or it can be damaged.
± Conduct a spark jump test only when necessary, make it as
short as possible, and do not open the throttle.
± Conduct engine compression checks within the shortest
possible time.
± Avoid situations which can result in engine misfire (e.g.
starting the engine when the fuel tank is nearly empty).

Engine Coolant Change
WARNING:
To help avoid danger of being burned, do not remove radia-
tor cap while engine and radiator are still hot. Scalding fluid
and steam can be blown out under pressure if cap is taken
off too soon.
1) Remove radiator cap when engine is cool.
2) Loosen radiator drain plug to drain coolant.
3) Remove reservoir, which is on the side of radiator, and drain.
4) Tighten plug securely. Also reinstall reservoir.
5) Fill radiator with specified amount of coolant, and run engine for
2 or 3 minutes at idle. This drives out any air which may still be
trapped within cooling system. STOP ENGINE. Add coolant as
necessary until coolant level reaches the filler throat of radiator.
Reinstall radiator cap.

CAUTION:
When changing engine coolant, use mixture of 50% wa-
ter and 50% ANTIFREEZE / ANTICORROSION COOLANT
for the market where ambient temperature falls lower
than ±16C (3F) in winter, and mixture of 70% water and
30% ANTIFREEZE / ANTICORROSION COOLANT for the
market where ambient temperature doesn't fall lower
than ±16C (3F).
Even in a market where no freezing temperature is antici-
pated, mixture of 70% water and 30% ANTIFREEZE / AN-
TICORROSION COOLANT should be used for the pur-
pose of corrosion protection and lubrication.
ITEM 1-6
Exhaust System Inspection
WARING:
To avoid danger of being burned, do not touch exhaust sys-
tem when it is still hot. Any service on exhaust system
should be performed when it is cool.
When carrying out periodic maintenance, or the vehicle is raised for
other service, check exhaust system as follows:

Check rubber mountings for damage, deterioration, and out of
position.

Check exhaust system for leakage, loose connections, dents and
damages.
If bolts or nuts are loose, tighten them to specification.

Check nearby body areas for damaged, missing, or misposi-
tioned parts, open seams, holes, loose connections or other de-
fects which could permit exhaust fumes to seep into the vehicle.

Make sure that exhaust system components have enough clear-
ance from the underbody to avoid overheating and possible dam-
age to the floor carpet.

Any defects should be fixed at once.

1B-8 AIR CONDITIONING (OPTIONAL)
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.

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

REMOVING MANIFOLD GAUGE SET
When A / C system has been charged with a specified amount of re-
frigerant, remove manifold gauge set as follows:
1) Close low pressure-side valve of manifold gauge set, (The high
pressure-side valve is closed continuously during the process
of charging.).
2) Close refrigerant container valve.
3) Stop engine.
4) Using shop rag, remove charging hoses from service valves.
This operation must be performed rapidly.
WARNING:
High pressure-side is naturally under high pressure.
So, care must be used to protect your eyes and skin.
5) Put caps on service valves.
LEAK-TESTING REFRIGERANT SYSTEM
Whenever a refrigerant leak is suspected in the system or any ser-
vice operation has been performed which may result in disturbing
lines or connections, it is advisable to test for leaks.
Common sense should be used in performing any refrigerant leak
test, since the need and extent of any such test will, in general, de-
pend upon the nature of a complaint and the type of a service per-
formed on the system.
LIQUID LEAK DETECTORS
There are a number of fittings and places throughout the air condi-
tioning system where a liquid leak detector solution may be used
to pinpoint refrigerant leaks.
By merely applying the solution to the area in question with a swab,
bubbles will form within seconds if there is a leak.
For confined areas, such as sections of the evaporator and con-
denser, an electronic (gas) leak detector is more practical for deter-
mining leaks.
WARNING:

To prevent explosions or fires, make sure that there are no
flammables in the vicinity.

When exposed to fire, the refrigerant turns into a poison-
ous gas (phosgene). Do not inhale this gas.

REPLENISHING COMPRESSOR OIL
When replacing air conditioning parts with new ones, it is necessary
to replenish oil by the amount supposedly remaining in each part.
When changing gas only
When it is unavoidable to change gas without replacing any compo-
nent part for engine removal and installation or for some other rea-
son, replenish 20 cc oil. When replenishing gas only, oil replenish-
ment it not necessary.
When replacing compressor
Compressor oil is sealed in each new compressor by the amount
required for air conditioner cycle. Therefore, when using a new
compressor for replacement, drain oil from it by the amount calcu-
lated as follows.
