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.
