CONDENSER
ON±VEHICLE INSPECTION
1. INSPECT CONDENSER FINS FOR BLOCKAGE OR
DAMAGE
If fins are clogged, wash them with water and dry with com-
pressed air.
NOTICE: Be careful not to damage the fins.
If fins are bent, straighten them with a screwdriver or pliers.
2. INSPECT CONDENSER AND FITTING FOR LEAKAGE
Using a gas leak tester, check for leakage.
If there is leakage, check the tightening torque at the joints.

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.
