Check that the tension is within A range on the auto tensioner
scale.
If the tension is not within the A range on the scale, replace the
belt with a new one.
HINT:
When replacing the drive belt with a new one, the belt's tension
should be within the B range on the belt tensioner scale.

DISASSEMBLY
1. PULL OUT EVAPORATOR TEMPERATURE SENSOR
2. REMOVE EXPANSION VALVE
Using a hexagon wrench (5.0mm, 0.20 in.), remove the 2 bolts
and separate the expansion valve and the evaporator.
Torque: 3.4 N´m (35 kgf´cm, 30 in.´lbf)
NOTICE:
Cap the open fittings immediately to keep moisture or dirt
out of the system.
HINT:
At the time of reassembly, lubricate 4 new O-rings with com-
pressor oil and install them to the valve. If evaporator is re-
placed, add compressor oil to the evaporator.
Add: 40 cc (1.4 fl.oz.)
Compressor oil: ND-OIL8 or equivalent

INSPECTION
1. CHECK EVAPORATOR FINS FOR BLOCKAGE
If the fins are clogged, remove them with compressed air.
NOTICE:
Never use water to clean the evaporator.
2. CHECK FITTINGS FOR CRACKS OR SCRATCHES
If necessary, repair or replace.

ON-VEHICLE INSPECTION
1. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Remove the glove compartment door.
(b) Remove the lower No. 2 finish panel
(See page BO-84).
(c) Remove the No. 1 cooler cover.
(1) Disconnect the connector clamp.
(2) Remove the 8 screws and No. 1 cooler cover.
(d) Using a gas leak detector, check for leaks of refrigerant.
If there is a leakage of refrigerant, check the tightening torque
at the joints or check the evaporator.
(e) Install the No. 1 cooler cover.
2. INSPECT EXPANSION VALVE
(a) Check amount of gas during refrigeration cycle.
(b) Set on manifold gauge set.
(c) Operate A/C system at ºMAX. COOLº for approx. 5 min-
utes.
(d) Check expansion valve.
Check the low pressure reading drops to 0 kPa (0
kgf/cm
2, 0 psi).
If the low pressure reading is not as specified, replace the ex-
pansion valve with the tubes.
