COMPRESSOR
ON-VEHICLE INSPECTION
1. Connect the manifold gauge set.
2. Run the engine at 1,500 rpm.
3. Check the compressor flow:
a) High pressure is not low and low pressure is not
higher than normal.
b) Metallic sound.
c) Check to be sure that the high-pressure and low-
pressure gauges show the same value immedi-
ately after the air conditioner is switched OFF.
If both gauges show the same value immediate-
ly, it can be assumed that the gasket or the valve
inside the compressor is damaged.
4. Stop the engine.
5. Check the shaft seal and others for leakage.
6. Inspect the drive plate pulley magnetic clutch for
signs of oil.
7. Check the clearance between the drive plate and
pulley. (Refer to page 16—21.)
If any of the above checks reveal faults, repair the
compressor or magnetic clutch.

REMOVAL OF COMPRESSOR
1. Perform the Oil Return Operation. (See below.)
2. Disconnect the battery ground cable.
3. Disconnect the clutch lead wire from the wiring
harness.
4. Discharge the refrigerant from the refrigeration
system.
5. Disconnect the two flexible hoses. Plug the open
fittings immediately to keep moisture out of the
system.
6. Loosen the drive belt.
7. Remove the compressor mounting bolts and the
compressor.

Oil Return Operation
1. If the refrigerant level is low, charge the system to
the specified amount.
2. Run the engine and air conditioner at idle and at
maximum cooling for at least 20 minutes.

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.

76G16X-638
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.
