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.

1B-12 AIR CONDITIONING (OPTIONAL)
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.

8) With about 20 mm (0.8 in.) of dry bulb thermometer (1) inserted
into center duct air outlet and another one set near evaporator
air inlet, read temperature indicated on each thermometer.

1B-26 AIR CONDITIONING (OPTIONAL)
CHARGING
CAUTION:

ALWAYS CHARGE THROUGH LOW PRESSURE-SIDE of A / C system at after the initial charging is per-
formed from the high-pressure side with the engine stopped.

NEVER CHARGE TO HIGH PRESSURE-SIDE of A / C system with engine running.

Do not charge while compressor is hot.

When installing tap valve to refrigerant container to make a hole there through, carefully follow direc-
tions given by manufacturer.

A pressure gauge should always be used before and during charging.

The refrigerant container should be emptied of refrigerant when discarding it.

The refrigerant container should not be heated up to 40C (104F) or over.

Refrigerant container should not be reversed in direction during charging. Reversing in direction
causes liquid refrigerant to enter compressor, causing troubles, such as compression of liquid refrig-
erant and the like.
NOTE:
The air conditioning system contains HFC-134a (R-134a).
Described here is a method to charge the air conditioning system with refrigerant from the refrigerant ser-
vice container.
When charging refrigerant recovered by using the refrigerant and recycling equipment (when recycling
refrigerant), follow the procedure described in the equipment manufacturer's instruction manual.
The initial charging of the A / C system is performed from the high-
pressure side with the engine stopped.
And next, this method must be followed by charging from the low-
pressure side with the engine running.
1) Check to make sure that hoses are routed properly after eva-
cuating the system.
2) Connect Low-side hose (1) and High side hose (2) of the man-
ifold gauge set (3) in position. Thus open refrigerant container
valve (4) to purge the charging line.
3) Open the high-pressure side valve (6) and charge refrigerant to
system.
4) After a while, open the low-pressure side valve (5) and close the
high-pressure side valve (6).
WARNING:
Make sure that high pressure-side valve is closed se-
curely.
5) Start engine and keep engine speed at 1500 r / min. Then, oper-
ate air conditioning.
6) Charge A / C system with refrigerant in vapor state. At this time,
refrigerant container should be held upright.
