GENERAL PRECAUTIONS
The WARNING and CAUTION below describe some general precautions that you should observe when servicing
a vehicle. These general precautions apply to many of the service procedures described in this manual, and they
will not necessarily be repeated with each procedure to which they apply.
WARNING:
Whenever raising a vehicle for service, be sure to follow the instructions under ªVEHICLE LIFTING
POINTSº on SECTION 0A.
When it is necessary to do service work with the engine running, make sure that the parking brake
is set fully and the transmission is in Neutral (for manual transmission vehicles) or Park (for automatic
transmission vehicles). Keep hands, hair, clothing, tools, etc. away from the fan and belts when the
engine is running.
When it is necessary to run the engine indoors, make sure that the exhaust gas is forced outdoors.
Do not perform service work in areas where combustible materials can come in contact with a hot
exhaust system. When working with toxic or flammable materials (such as gasoline and refrigerant),
make sure that the area you work in is well-ventilated.
To avoid getting burned, keep away from hot metal parts such as the radiator, exhaust manifold, tail-
pipe, muffler, etc.
New and used engine oil can be hazardous. Children and pets may be harmed by swallowing new or
used oil. Keep new and used oil and used engine oil filters away from children and pets.
Continuous contact with used engine oil has been found to cause [skin] cancer in laboratory animals.
Brief contact with used oil may irritate skin. To minimize your exposure to used engine oil, wear a
long-sleeve shirt and moisture-proof gloves (such as dishwashing gloves) when changing engine oil.
If engine oil contacts your skin, wash thoroughly with soap and water. Launder any clothing or rags
if wet with oil, recycle or properly dispose of used oil and filters.
Make sure the bonnet is fully closed and latched before driving. If it is not, it can fly up unexpectedly
during driving, obstructing your view and resulting in an accident.
CAUTION:
Before starting any service work, cover fenders, seats and
any other parts that are likely to get scratched or stained dur-
ing servicing. Also, be aware that what you wear (e.g, but-
tons) may cause damage to the vehicle's finish.
When performing service to electrical parts that does not re-
quire use of battery power, disconnect the negative cable of
the battery.

0A-8 GENERAL INFORMATION
When removing the battery, be sure to disconnect the nega-
tive cable first and then the positive cable. When reconnect-
ing the battery, connect the positive cable first and then the
negative cable, and replace the terminal cover.
When removing parts that are to be reused, be sure to keep
them arranged in an orderly manner so that they may be rein-
stalled in the proper order and position.
Whenever you use oil seals, gaskets, packing, O-rings, lock-
ing washers, split pins, self-locking nuts, and certain other
parts as specified, be sure to use new ones. Also, before
installing new gaskets, packing, etc., be sure to remove any
residual material from the mating surfaces.
Make sure that all parts used in reassembly are perfectly
clean.
When use of a certain type of lubricant, bond or sealant is
specified, be sure to use the specified type.
ªAº: Sealant 99000-31150
Be sure to use special tools when instructed.

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).

COMPRESSION SYSTEM DIAGNOSIS
Compressor troubles are mainly following three types: gas leakage, noise and insufficient pressure.
Compressor gas leakages in most cases develop from the shaft seal. When detecting gas leakage, always use
a leak tester. If a small amount of oil seeps out from the shaft seal, there is no necessity of replacing the seal. The
shaft seal has been designed to allow a small amount of oil to leak out for lubricating purpose. Thus, the shaft seal
should be replaced only when a large amount of compressor oil is leaking out or when gas leakage is discovered
by using gas tester.
In regard to noise and insufficient pressure, repairs should be made only after diagnosing the trouble properly.

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.

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.
ªCº = ªAº ± ªBº
