MAINTENANCE AND LUBRICATION 0B-21
STEERING
Check to ensure that steering wheel is free from instability, or abnormally heavy feeling.
Check that the vehicle does not wander or pull to one side.
ENGINE
Check that engine responds readily at all speeds.
Check that engine is free from abnormal noise and abnormal vibration.
BODY, WHEELS AND POWER TRANSMITTING SYSTEM
Check that body, wheels and power transmitting system are free from abnormal noise and abnormal vibration or
any other abnormal condition.
METERS AND GAUGE

ABNORMAL NOISE FROM CRANKSHAFT PULLEY
ABNORMAL NOISE FROM TENSION PULLEY
ABNORMAL NOISE FROM A/C EVAPORATOR
ABNORMAL NOISE FROM BLOWER FAN MOTOR
Condition Possible Cause Correction
A large rattling noise
is heard at idle or sud-
den acceleration.Loosen crankshaft pulley bolt Retighten bolt.
Condition Possible Cause Correction
Clattering noise is
heard from pulley.Worn or damaged bearing Replace tension pulley.
Pulley cranks upon
contact.Cracked or loose bracket Replace or retighten bracket.
Condition Possible Cause Correction
Whistling sound is
heard from A/C evapo-
rator.Depending on the combination of the interior/
exterior temperatures, engine rpm and refriger-
ant pressure, the refrigerant flowing out of the
expansion valve may, under certain conditions,
make a whistling soundAt times, slightly decreasing refrig-
erant volume may stop this noise.
Inspect expansion valve and
replace if faulty.
Condition Possible Cause Correction
Blower fan motor
emits a chirping
sound in proportion to
its speed of rotation.Worn or damaged motor brushes or commuta-
torRepair or replace blower fan motor.
Fluttering noise or
large droning noise is
heard from blower fan
motor.Leaves or other debris introduced from fresh air
inlet to blower fan motorRemove debris and make sure that
the screen at fresh air inlet is intact.

REFRIGERANT RECOVERY, EVACUATING AND CHARGING
OPERATION PROCEDURE FOR REFRIGERANT CHARGING
WARNING:
 Your eyes should not be exposed to refrigerant (liquid).
Any liquid HFC-134a (R-134a) escaping by accident shows a temperature as low as approximately
–6°C (32°F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a
serious 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 eyes, 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 temper-
ature 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 hazard-
ous to health.

7) When refrigerant container (1) is emptied, use the following
procedure to replace it with a new refrigerant container (1).
a) Close low pressure valve.
b) Replace empty container (1) with a refrigerant container
which has been charged with refrigerant. When using
refrigerant container tap valve (2), use the following proce-
dure for replacement.
i) Retract needle (3) and remove refrigerant container tap
valve (2) by loosening its plate nut (4).
ii) Install previously-removed refrigerant container tap valve
(2) to a new refrigerant container (1).
c) Purge any air existing in center charging hose
When using refrigerant container tap valve, use the follow-
ing procedure to purge air.
i) Once fully tighten refrigerant container tap valve (1), and
then loosen (open) plate nut (2) slightly.
ii) Open low pressure side valve (3) of manifold gauge set
(4) a little.
iii) As soon as refrigerant comes out with a “hiss” through a
clearance between refrigerant container and tap valve,
tighten plate nut (2) as well as low pressure side valve (3).
iv) Turn handle of tap valve (1) clockwise so that its needle is
screwed into the new container to make a hole for refriger-
ant flow.
8) After the system has been charged with specified amount
(330 – 390 g) of refrigerant or when low pressure gauge (1)
and high pressure gauge (2) have indicated the following
specified amount, close low pressure side valve (3) on mani-
fold gauge set (4). At this time, look into the sight glass (5) of
condenser outlet pipe (6) and check that there are no bub-
bles (7) in it, which means that the system is fully charged.

ON-VEHICLE SERVICE
SERVICE PRECAUTION
When servicing air conditioning system, note the following instructions.
REFRIGERANT LINE
Never use heat for bending pipes. When bending a pipe, try to make its bending radius as slight as possible.
Keep internal parts of air conditioning free from moisture and dirt. When disconnecting any line from system,
install a blind plug or cap to the fitting immediately.
When connecting hoses and pipes, apply a few drops of compressor oil (refrigerant oil) to seats of coupling
nuts and O-ring.
When tightening or loosening a fitting, use two wrenches, one for turning and the other for support.
Tighten flared nuts by the following specified torque.
Tightening torque
8 mm pipe : 13 N·m (1.3 kg-m, 9.5 lb-ft)
12 mm pipe : 23 N·m (2.3 kg-m, 16.6 lb-ft)
14.5 mm pipe : 33 N·m (3.3 kg-m, 23.8 lb-ft) WARNING:
Should refrigerant HFC-134a (R-134a) strike your eye(s), consult a doctor immediately.
 Do not use your hand to rub affected eye(s). Instead, use quantities of fresh cold water to splash it
over affected area to thus gradually raise its temperature above the freezing point.
 Obtain proper treatment as soon as possible from a doctor or eye specialist. Should liquid refriger-
ant HFC-134a (R-134a) get on your skin, such affected part should be treated in the same manner as
when skin is frostbitten or frozen.
