RECEIVER-DRIER 16
RECEIVER-DRIER
ON-VEHICLE INSPECTION
1. Use a leak detector to check the sight glass, the
fusible plug, and the fittings for leakage.
Repair or replace, if necessary.
2. Check the receiver-drier for clogging.
a) Run the engine at fast idle with the air conditioner
on.
b) Check both inlet and outlet temperatures.
If there is a great difference between the two tem-
peratures, replace the receiver-drier.

REMOVAL OF RECEIVER-DRIER
1. Discharge the air conditioning system.
(Refer to page 16—9)
2. Disconnect the two liquid line pipes from the
receiver-drier.
Note:
Plug the open fittings immediately to keep
moisture out of the system.
3. Remove the receiver-drier from the bracket.
INSTALLATION OF RECEIVER-DRIER
1. Install the receiver-drier onto the bracket.
Note:
Do not remove the blind plugs until ready for
connection.
2. Connect the two liquid line pipes to the
receiver-drier.
Tightening torque:
15—25 N m (1.5—2.5 m-kg, 11—18 ft-lb)
3.
If
the receiver-drier is replaced with a new one, add
compressor oil to the compressor.
Compressor oil: 10 cc (0.61 cu in)

76G16X-006
DISASSEMBLY OF COOLING UNIT
1. Remove the screws by using a screwdriver.
2. Remove the upper case.
3. Remove the thermostat.
4. Remove the lower case.
5. Remove the expansion valve.
INSPECTION OF EVAPORATOR
1. Check the evaporator fins for blockage. If the fins
are clogged, clean them with compressed air.
Caution:
Never use water to clean the evaporator.
2. Check the fittings for cracks or scratches. Repair
or replace, if necessary.
ASSEMBLY OF COOLING UNIT
1. Connect the expansion valve to the inlet fitting of
the evaporator. Tighten the two bolts by using a
wrench.
Note:
Be sure that the O-ring is positioned on the
pipe fitting.
Specified torque: 2.7—3.4 N-m
(0.27—0.35 m-kg, 2.0—2.5 ft-lb)
2. Install the lower case onto the evaporator.
3. Install the thermostat in its original position.
4. Install the lower case onto the evaporator.

1 6 COOLING UNIT
INSTALLATION OF COOLING UNIT
1. Install the cooling unit by using the two nuts.
Note
Adjust and position the unit so that its con-
nections match those of the heater unit and
the blower unit.
2. Connect the drain hose.

5. Connect the liquid line high-pressure pipe and suc-
tion low-pressure pipe to the cooling unit.
Tightening torque:
15—22 Nm (1.5—2.5 m-kg, 11—18 ft-lb)
6. Install the instrument lower panel, shower duct and
glove box.
7. If the evaporator is replaced, add compressor oil
to the compressor.
Compressor oil: 50 cc (3.05 cu in)

REFRIGERANT LINES 1 6
REFRIGERANT LINES
ON-VEHICLE INSPECTION
1. Check all piping connections for leakage by using a leak detector. Replace if necessary.
2. Check that the hose and pipe clamps are not loose.
Tighten or replace, if necessary.
REPLACEMENT OF REFRIGERANT LINES
1. Discharge the air conditioning system. (Refer to page 16—9)
2. Replace the faulty pipe or hose.
Note:
Plug all open fittings immediately to keep moisture out of the system.
Tightening torque (fittings):
Location Tightening torque
