Service Specifications/Lubricant/Sealants14-2
GENERAL INFORMATION14100010125
The cooling system is designed to keep every part
of the engine at appropriate temperature in
whatever condition the engine may be operated.
The cooling method is of the water-cooled, pressure
forced circulation type in which the water pump
pressurizes coolant and circulates it throughout the
engine. If the coolant temperature exceeds the
prescribed temperature, the thermostat opens to
circulate the coolant through the radiator as well
so that the heat absorbed by the coolant may be
radiated into the air.The water pump is of the centrifugal type and is
driven by the drive belt from the crankshaft.
The radiator is the corrugated fin, down flow type.

HANDLING OF AUTO WINDOW SEALER
Keep the sealant in a cool place, not exposed to the direct
rays of the sun. Do not place any heavy article on the sealant
nor press it, otherwise it will become deformed. Avoid storing
the sealant for more than 6 months, because it will lose its
sealing effect.
BODY PINCH-WELD FLANGE SERVICING.
Before servicing the body pinch-weld flange, remove old
adhesive completely. If the flange requires painting, bake
it after painting is completed.

Window glass side
Reusing the glassReplacing the glass
Cleaning of adhesion surface
Competely cut off all of the residual
adhesive. Clean the adhesion surface
with isopropyl alcohol, and let dry for

SRS ± SRS Diagnosis Unit (SDU)/Air Bag Module and Clock Spring52B-28
INSPECTION52400220093

Check the SDU and brackets for dents, cracks or
deformation.

Check connector for damage, and terminals for
deformation.
Caution
If a dent, crack, deformation or rust is discovered,
replace the SDU with a new one.
NOTE
For checking of the SDU other than described above,
refer to the section concerning troubleshooting. (Refer
to P.52B-6.)
AIR BAG MODULE AND CLOCK SPRING52400240143
Caution
1. Disconnect the battery (±) terminal and wait
for 60 seconds or more before starting work.
Furthermore, the disconnected battery
terminal should be covered with tape to
insulate it. (Refer to P.52B-3, No.4.)
2. Never attempt to disassemble or repair the
air bag modules or clock spring.
If faulty, replace it.
3. Do not drop the air bag modules or clock
spring or allow contact with water, grease
or oil.
Replace it if a dent, crack, deformation or
rust is detected.4. The air bag modules should be stored on
a flat surface and placed so that the pad
surface is facing upward.
Do not place anything on top of it.
5. Do not expose the air bag modules to
temperatures over 93C.
6. After deployment of an air bag, replace the
clock spring with a new one.
7. Wear gloves and safety glasses when
handling air bags that have already
deployed.
8. An undeployed air bag module should only
be disposed of in accordance with the
procedures (Refer to P.52B-34.)

CHASSIS ELECTRICAL ± Battery54-5
CHARGING54100110029
1. When charging a battery while still installed in the vehicle,
disconnect the battery cables to prevent damage to
electrical parts.
2. The current normally used for charging a battery should
be approximately 1/10th of the battery capacity.
3. When performing a quick-charging due to lack of time,
etc., the charging current should never exceed the battery
capacity as indicated in amperes.
4. Determining if charging is completed.
(1) If the specific gravity of the battery fluid reaches
1.250 ± 1.290 and remains constant for at least one
hour.
(2) If the voltage of each cell reaches 2.5 ± 2.8 V and
remains constant for at least one hour.
Caution
1. Be careful since the battery fluid level may rise
during charging.
2. Keep all sources of fire away while charging
because there is a danger of explosion.
3. Be careful not to do anything that could generate
sparks while charging.
4. When charging is completed, replace the battery
caps, pour clean water over the battery to remove
any sulfuric acid and dry.

± General Information HEATER, AIR CONDITIONER
AND VENTILATION55-3
GENERAL INFORMATION55200010121
The heater system uses a two-way-flow full-air-mix
system that features high performance and low
operating noise, and includes an independent face
air blowing function and a cool air bypass function.The A/C system is basically the same as the
conventional system, but a new refrigerant system
has been adopted as a response to restrictions
on the use of chlorofluorocarbons.

Refrigerant and quantity gR-134a (HFC-134a), Approx. 550 ± 600
SAFETY PRECAUTIONS
Because R-134a refrigerant is a hydrofluorocarbon
(HFC) which contains hydrogen atoms in place of
chlorine atoms, it will not cause damage to the
ozone layer.
Refrigerant R-134a is transparent and colourless
in both the liquid and vapour state. Since it has
a boiling point of ± 29.8
C, at atmospheric pressure,
it will be a vapour at all normal temperatures and
pressures. The vapour is heavier than air,
non-flammable, and nonexplosive. The following
precautions must be observed when handling
R-134a.Caution
Wear safety goggles when servicing the
refrigeration system.
R-134a evaporates so rapidly at normal
atmospheric pressures and temperatures that it
tends to freeze anything it contacts. For this reason,
extreme care must be taken to prevent any liquid
refrigerant from contacting the skin and especially
the eyes. Always wear safety goggles when
servicing the refrigeration part of the A/C system.
Keep a bottle of sterile mineral oil handy when
working on the refrigeration system. Should any
liquid refrigerant get into the eyes, use a few drops
of mineral oil to wash them out. R-134a is rapidly
absorbed by the oil. Next splash the eyes with
plenty of cold water. Call your doctor immediately
even though irritation has ceased after treatment.

General Information/Service Specifications/
Lubricants/Sealant HEATER, AIR CONDITIONER
AND VENTILATION ±55-4
Caution
Do not heat R-134a above 40
C
In most instances, moderate heat is required to
bring the pressure of the refrigerant in its container
above the pressure of the system when charging
or adding refrigerant.
A bucket or large pan of hot water not over 40
C
is all the heat required for this purpose. Do not
heat the refrigerant container with a blow torch
or any other means that would raise temperature
and pressure above this temperature. Do not weld
or steam clean on or near the system components
or refrigerant lines.
Caution
Keep R-134a containers upright when charging
the system.When metering R-134a into the refrigeration system
keep the supply tank or cans in an upright position.
If the refrigerant container is on its side or upside
down, liquid refrigerant will enter the system and
damage the compressor.
Caution
1. The leak detector for R-134a should be used
to check for refrigerant gas leaks.
2. Do not allow liquid refrigerant to touch bright
metal.
Refrigerant will tarnish bright metal and chrome
surfaces, and in combination with moisture can
severely corrode all metal surfaces.
