ON±VEHICLE INSPECTION
1. CHECK QUANTITY OF GAS DURING REFRIGERATION CYCLE
2. SET ON MANIFOLD GAUGE SET (See page AC±19)
3. RUN ENGINE
Run the engine at 1,500 rpm for at least 5 minutes.
Then check that the high pressure reading is 1.37 ± 1.57 MPa (14 ± 16 kgf/cm
2, 199 ± 228 psi).
4. CHECK EXPANSION VALVE
If the expansion valve is faulty, the low pressure reading will drop to 0 kPa (0 kgf/cm
2, 0 psi).
HINT:
When the low pressure drops to 0 kPa (0 kgf/cm
2, 0 psi), check the receiver's IN and OUT sides is no temper-
ature difference.

3. REMOVE BLOWER UNIT (See page AC±35)
4. REMOVE EXPANSION VALVE
(a) Remove the piping clamp.
(b) Ply out the packing.
HINT:
Do not reuse the packing.
(c) Using a hexagon wrench, remove the 2 bolts and sepa-

INSTALLATION
1. INSTALL LIQUID TUBE AND SUCTION TUBE TO EX-
PANSION VALVE
HINT:
Lubricate 4 new O±rings with compressor oil and install the
tubes.
2. INSTALL NEW PACKING ON EXPANSION VALVE
(a) Cut off packing paper and peel off the packing paper, as
shown in the illustration.
HINT:
Leave the packing paper untaped on the tube side so that the
installing bolt hole for remains visible.
(b) Apply the packing on the expansion valve.
NOTICE:
Do not overtape the packing beyond the expansion valve
edge.

3. INSTALL EXPANSION VALVE
(a) Install the expnaion valve with the 2 bolts.
Torque: 5.4 N´m (55 kgf´cm, 48 in.´lbf)
NOTICE:
When installing the expansion valve, take care so that the
packing is not jammed with the evaporator.
HINT:
Lubricate 2 new O±rings with compressor oil and install O±rings
on the expansion valve.
(b) Peel off the remaing packing paper and apply the packing
to expansion valve.
4. INSTALL BLOWER UNIT (See page AC±38)
5. INSTALL GLOVE COMPARTMENT
(See page BO±81)
6. CONNECT LIQUID TUBE AND SUCTION TUBES TO
A/C UNIT (See page AC±33)
7. EVACUATE AIR FROM REFRIGERATION SYSTEM
AND CHARGE SYSTEM WITH REFRIGERANT
Specified amount: 800 ± 50 g (28.22 ± 1.76 oz.)
8. INSPECT FOR LEAKAGE OF REFRIGERANT
Using a gas leak detector, check for leakage of refrigerant.
If there is leakage, check the tightning torque at the joints.
