GENERAL INFORMATION 0A-17
Improperly formed or damaged terminals.
Check each connector terminal in problem circuits carefully
to ensure good contact tension by using the corresponding
mating terminal.
If contact tension is not enough, reform it to increase contact
tension or replace.
Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor con-
nection by shaking it by hand lightly. If any abnormal condi-
tion is found, repair or replace.
Wire insulation which is rubbed through, causing an intermit-
tent short as the bare area touches other wiring or parts of
the vehicle.
Wiring broken inside the insulation. This condition could
cause continuity check to show a good circuit, but if only 1 or
2 strands of a multi-strand-type wire are intact, resistance
could be far too high.
If any abnormality is found, repair or replace.
1. Check contact tension by inserting and removing just once.
2. Check each terminal for bend and proper alignment.

GENERAL INFORMATION 0A-25
FASTENER INFORMATION
METRIC FASTENERS
Most of the fasteners used for this vehicle are metric. When replacing any fasteners, it is most important that
replacement fasteners be the correct diameter, thread pitch and strength.
FASTENER STRENGTH IDENTIFICATION
Most commonly used metric fastener strength property classes are 4T, 6.8, 7T, 8.8 and radial line with the class
identification embossed on the head of each bolt. Some metric nuts will be marked with punch, 6 or 8 mark
strength identification on the nut face. Figure shows the different strength markings.
When replacing metric fasteners, be careful to use bolts and nuts of the same strength or greater than the origi-
nal fasteners (the same number marking or higher). It is likewise important to select replacement fasteners of
the correct diameter and thread pitch. Correct replacement bolts and nuts are available through the parts divi-
sion.
Metric bolts : Identification class numbers or marks correspond to bolt strength (increasing numbers represent
increasing strength).
STANDARD TIGHTENING TORQUE
Each fastener should be tightened to the torque specified in each section of this manual. If no description or
specification is provided, refer to the following tightening torque chart for the applicable torque for each fastener.
When a fastener of greater strength than the original one is used, however, use the torque specified for the orig-
inal fastener.
1. Nut strength identification
NOTE:
 For the flanged bolt, flanged nut and self-lock nut of 4T and 7T strength, add 10% to the tightening
torque given in the chart below.
 The chart below is applicable only where the fastened parts are made of steel light alloy.

1B-10 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 15 – 35°C (59 – 95°F).
2) Make sure that high pressure valve (1) and low pressure
valve (2) of manifold gauge set (3) are firmly closed.
3) Connect high pressure charging hose (4) to high pressure
service valve (5), and connect low pressure charging hose
(6) to low pressure service valve (7).
4) Bleed the air in charging hoses (4), (6) by loosening their
respective nuts on manifold gauge set (3), utilizing the refrig-
erant pressure. When a hissing sound is heard, immediately
tighten nut.
5) Warm up engine to normal operating temperature (engine
coolant temperature at 80 – 90°C (176 – 194°F)) and keep it
at specified idle speed. (Radiator cooling fan should not be
working when checking pressure and temperature.)
6) Turn A/C switch to ON position, and set blower fan switch at
“H” (4th position), temperature dial at “COOL”, air outlet con-
trol dial at “FACE” and fresh/recirculation control dial at
“RECIRCULATION”. (Confirm that A/C compressor and radi-
ator/condenser cooling fan are working.)
Keep all windows, doors and engine food open.
Performance diagnosis condition
7) With dry bulb thermometer (1) inserted into center duct air
outlet and another one set near evaporator air inlet, read
temperature indicated on each thermometer. CAUTION:
Do not interchange high and low pressure charging
hoses by mistake.
Ambient temperature 15 – 35°C (59 – 95°F)
Engine rpm Keep to 1,500 rpm.

AIR CONDITIONING (OPTIONAL) 1B-23
1) Connect high charging hose (1) and low charging hose (2) of
manifold gauge set (3) respectively as follows :
High charging hose (1) → High pressure charging valve (4)
on condenser outlet pipe
Low charging hose (2) → Low pressure charging valve (5)
on suction pipe
2) Attach center charging hose (6) of manifold gauge set (3) to
vacuum pump (7).
3) Operate vacuum pump (7), and then open discharge side
valve (Hi) (8) of manifold gauge set (3).
If there is no blockage in the system, there will be an indica-
tion on high pressure gauge (9).
In this case, open the other side valve (Lo) (10) of the set
and repair the system.
4) Approximately 10 minutes later, low pressure gauge (11)
should show a vacuum lower than –760 mmHg providing no
leakage exists.
5) Evacuation should be carried out for a total of at least 15
minutes.
6) Continue evacuation until low pressure gauge (9) indicates a
vacuum less than –760 mmHg, and then close both valves
(8), (10).
7) Stop vacuum pump (7). Disconnect center charging hose (6)
from pump inlet. Now, the system is ready for charging
refrigerant.
CHECKING SYSTEM FOR PRESSURE LEAKS
After completing the evacuation, close manifold gauge high pres-
sure valve and low pressure valve and wait 10 minutes. Verify
that low pressure gauge reading has not changed.NOTE:
 If the system does not show a vacuum below –760
mmHg, close both valves, stop vacuum pump and
watch movement of low pressure gauge.
 Increase in the gauge reading suggests existence of
leakage. In this case, repair the system before continu-
ing its evacuation.
 If the gauge shows a stable reading (suggesting no
leakage), continue evacuation.
CAUTION:
If the gauge reading moves closer to “0”, there is a leak
somewhere. Inspect the tubing connections, make nec-
essary corrections, and evacuate system once again,
making sure that there are no leaks.

MAGNET CLUTCH
INSPECTION
Check clutch plate and clutch pulley for wear and oil soaked
conditions respectively.
Check clutch pulley bearing for noise, wear and grease leak-
age.
Measure clutch coil for resistance at 20°C (68°F).
If the measured resistance does not remain within tolerance,
replace magnet clutch assembly.
