EXPANSION VALVE
ON±VEHICLE INSPECTION
1. CHECK QUANTITY OF GAS DURING REFRIGERATION
CYCLE
2. INSTALL MANIFOLD GAUGE SET
3. RUN ENGINE
Run the engine at 1,500 rpm for at least 5 minutes. Then
check that the high pressure reading is 1.371.57 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), feel the receiver's IN and OUT sides for zero tempera-
ture difference.
EXPANSION VALVE REMOVAL
1. REMOVE EVAPORATOR
(See page AC±82)
2. REMOVE EXPANSION VALVE
Using a hexagon wrench, remove the 2 bolts and separate
the evaporator and expansion valve.
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf)
INSTALLATION HINT: Lubricate the new O±ring with com-
pressor oil and install the tubes.

Condenser Fan:
1. INSPECT CONDENCER
(a) Disconnect the fan connector.
(b) Connect battery and ammeter to the cooling fan connector.
(c) Check that the condenser fan rotates smoothly, and check
the reading on the ammeter.
