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.

PERFORMANCE DIAGNOSIS
1) Confirm that vehicle and environmental conditions are as fol-
lows.

Vehicle is not exposed to direct sun.

Ambient temperature is within 15C ± 35C (59F ± 95F).
2) Make sure that high pressure valve (1) and low pressure valve
(2) of manifold gauge are firmly closed.
3) Connect high pressure charging hose (3) to high pressure ser-
vice valve (5) on vehicle, and connect low pressure charging
hose (4) to low pressure service valve (6) on vehicle.
4) Bleed the air in charging hoses (3), (4) by loosening their respec-
tive nuts on manifold gauge, utilizing the refrigerant pressure.
When a hiss is heard, immediately tighten nut.
CAUTION:
Do not interchange high and low pressure charging
hoses by mistake.
5) Warm up engine to normal operating temperature (engine cool-
ant temperature at 80 ± 90C (176 ± 194F)) and keep it at spe-
cified idle speed. (Radiator cooling fan should not be working
when checking pressure and temperature.)
6) Turn A / C switch ON, and set blower switch at ªHIº (4th position),
temperature control knob at ªCOOLº, air outlet control knob at
ªFACEº, fresh / circulation control knob at ªCIRCULATIONº.
(Confirm that A / C compressor and condenser fan are working.)
7) Keep all windows, doors and engine food open.

5) Disconnect coupler from dual pressure switch (1).
6) Disconnect condenser outlet pipe (3).
7) Disconnect condenser cooling fan motor coupler (2).
8) Remove condenser with fan.
NOTE:
Be careful not to damage fins of condenser and radiator.
9) Remove A / C condenser cooling fan assembly from condenser.
INSTALLATION
Reverse removal sequence to install condenser, noting following
point.
1) When replacing condenser, add 20 to 30 cc of refrigerating oil
from compressor suction-side.
2) Evacuate and charge system according to previously-described
procedure.
