DISPOSAL
1. FULLY EXTEND SHOCK ABSORBER ROD
2. Normal Type:
DRILL HOLE TO REMOVE GAS FROM CYLINDER
Using a drill, make a hole in the cylinder, as shown in the illustra-
tion to discharge the gas inside.
CAUTION:
The discharged gas is harmless, but be careful of chips
which may fly out when drilling.
3. Auto Leveler Type:
DRILL HOLE TO REMOVE GAS FROM CYLINDER
Using a drill, make a hole on the shaded area of the cylinder,
as shown in the illustration to discharge the gas inside.
CAUTION:

Be sure to perform the procedure in the order, the
high pressure chamber and the low pressure cham-
ber.

Wear protective goggles and cover the absorber with
a plastic bag or like when boring.

The discharged gas is harmless, but be careful of
chips which may fly out when drilling.

(c) Connect terminals 2 and 3 on the wire harness side con-
nector through a 3.4 watts test bulb.
(d) Turn the ignition switch ON, check that the bulb comes on
and the receiver gauge needle moves towards the full
side.
HINT:
Because of silicon oil in the gauge, it will take a short time for
the needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
4. INSPECT FUEL LEVEL WARNING LIGHT OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 2 and 3 on the wire harness side con-
nector.
(c) Turn the ignition switch ON and check that the warning
light comes on.
If the warning light does not come on, test the bulb or inspect
the wire harness.
5. INSPECT ENGINE COOLANT TEMPERATURE SEND-
ER GAUGE RESISTANCE
(a) Disconnect the engine coolant temperature sender
gauge.
(b) Measure the resistance between terminals 1 and 2 of the
connector according to the value(s) in the table below.
Temperature °C (°F)Resistance (W)
±20 (±4)13,840 to 16,330
20 (68)2,320 to 2,590
80 (176)310 to 326
110 (230)139.9 to 143.5
If resistance value is not as specified, replace the engine cool-
ant sender gauge.
6. INSPECT OIL PRESSURE SENDER OPERATION
(a) Disconnect the connector from the oil pressure sender.
(b) Check that no continuity exists between terminal and
ground with the engine stopped.
(c) Check that continuity exists between terminal and ground
with the engine running.
HINT:
Oil pressure should be over 24.5 kPa (0.25 kgf/cm
2, 3.55 psi).
If operation is not as specified, replace the oil pressure sender.

HOOD SUPPORT
REPLACEMENT
1. REMOVE HOOD SUPPORT
(a) Remove the bolt and hood support from the hood.
HINT:
While supporting the hood by hand, remove the hood support
from the hood.
(b) Remove the bolt and hood support.
2. IF NECESSARY, REPLACE HOOD SUPPORT
NOTICE:
Handling the hood support

Do not disassemble the support as the cylinder is
filled with pressurized gas.

If the hood support is to be replaced, drill a 2.0 ± 3.0
mm (0.079 ± 0.118 in.) hole in the area shown in the il-
lustration to completely release the high pressure
gas before disposing of it.

When drilling, chips may fly out so work carefully.

The gas is colorless, odorless and non ± toxic.

When working, handle the hood support carefully.
Never score or scratch the exposed part of the piston
rod, and allow any paint or oil to get on it.

Do not turn the piston rod and cylinder with the hood
support fully extended.
3. INSTALL HOOD SUPPORT
(a) Install the bolt and hood support to the body.
Torque: 22 N´m (224 kgf´cm, 16 ft´lbf)
(b) Install the bolt and hood support to the hood.

1. REMOVE BACK DOOR STAY
(a) Slide the clip, then remove the back door stay from the
back door.
HINT:
While supporting the back door with your hand, remove the
back door stay.
(b) Slide the clip, then remove the bolts and back door stay
from the body.
2. IF NECESSARY, REPLACE BACK DOOR STAY
NOTICE:
When handling the back door stay.

Do not disassemble the back door stay because the
cylinder is filled with pressurized gas.

If the back door stay is to be replaced, drill a 2.0 ± 3.0
mm (0.079 ± 0.118 in.) hole in the bottom of the back
door stay as shown in the illustration to completely
release the high±pressure gas before disposing of it.

When drilling, chips may fly out so work carefully.

The gas is colorless, odorless and non±toxic.

When working, handle the back door stay carefully.
Never score or scratch the exposed part of the piston
rod, and never allow paint or oil to get on it.

Do not turn the piston rod and cylinder with the back
door stay fully extended.
3. INSTALL BACK DOOR STAY
(a) Install the bolts and back door stay to the body.

PRECAUTION
1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED
AREA OR NEAR AN OPEN FLAME
2. ALWAYS WEAR EYE PROTECTION
3. BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN
YOUR EYES OR ON YOUR SKIN
If liquid refrigerant gets in your eyes or on your skin.
(a) Wash the area with lots of cool water.
CAUTION:
Do not rub your eyes or skin.
(b) Apply clean petroleum jelly to the skin.
(c) Go immediately to a physician or hospital for professional
treatment.
4. NEVER HEAT CONTAINER OR EXPOSE IT TO OPEN
FLAME
5. BE CAREFUL NOT TO DROP CONTAINER OR NOT TO
APPLY PHYSICAL SHOCKS TO IT
6. DO NOT OPERATE COMPRESSOR WITHOUT
ENOUGH REFRIGERANT IN REFRIGERATION SYS-
TEM
If there is not enough refrigerant in the refrigerant system, oil lu-
brication will be insufficient and compressor burnout may occur.
Necessary care should be taken to avoid this.
7. DO NOT OPEN PRESSURE MANIFOLD VALVE WHILE
COMPRESSOR IS OPERATING
If the high pressure valve is opened, refrigerant flows in the re-
verse direction and could cause the charging cylinder to rup-
ture, so open and close only the low pressure valve.
8. BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH
REFRIGERANT
If refrigerant is overcharged, it causes problems such as insuffi-
cient cooling, poor fuel economy, engine overheating, etc.
