16 CONDENSER
CONDENSER
ON-VEHICLE INSPECTION
1. Check the condenser fins for blockage or damage.
If the fins are clogged, clean them with compressed air.
If the fins are bent, straighten them with a screwdriver or pair of pliers.
2. Check the condenser fittings for leakage.
Repair or replace, if necessary.
REMOVAL OF CONDENSER
1. Discharge the air conditioning system. (Refer to page 16—9.)
2. Remove the front grille and the air seal cover.
3. Disconnect the discharge flexible hose from the condenser inlet fitting.
4. Disconnect the liquid line pipe from the condenser outlet fitting.
Note:
Plug the open fittings immediately to keep moisture out of the system.
6. Remove the condenser.
Condenser Radiator
Hole
76G16X-637
INSTALLATION OF CONDENSER
1. Install the condenser by using the two bolts and two nuts.
2. Connect the liquid line pipe and the discharge flexible hose to the condenser.
Tightening torque:
Liquid line pipe: 15—25 Nm (1.5—2.5 m-kg, 11—18 ft-lb)
Discharge flexible hose: 15—22 N-m (1.5—2.2 m-kg, 11—16 ft-lb)
3. Install the front grille and the air seal cover.
4. If the condenser is replaced with a new one, supply compressor oil.
Compressor oil: 30 cc (1.83 cu in)
5. Evacuate, charge, and test the air conditioning system.

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)

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)
