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. INSPECT HEATER RADIATOR
If the fins are clogged, clean them with compressed air.
2. INSPECT BLOWER MOTOR OPERATION
Connect battery positive (+) lead to terminal 1 and battery neg-
ative (-) lead to terminal 2, then check that the motor rotates
smoothly.
If operation is not as specified, replace the blower motor.
3. INSPECT AIR MIX SERVOMOTOR (See page DI-1354)
4. INSPECT AIR MIX DAMPER POSITION SENSOR
(See page DI-1345)
