5. O-RING CONNECTIONS
•Always use a new O-ring.
•In order to keep the O-rings free of lint which can
cause a refrigerant gas leak, perform operations
without gloves and cloth.
•Apply compressor oil to O-rings to avoid sticking,
before installation.
•Use a torque wrench to tighten the O-ring fittings.
Over-tightening will cause damage to the O-ring
and cause tube end distortion.
•If the work is interrupted before completing pipe
connections, recap the tubes, components and fit-
tings with a plug or tape to prevent foreign matter
from entering.
•Visually check the surfaces and mating surfaces
of O-rings, threads and connecting points. If a fail-
ure is found, replace the applicable parts.
•Install the O-rings at a right angle to tube beads.
•Use compressor oil specified in the service man-
ual to lubricate the O-rings.
Apply oil to the top and sides of O-rings before in-
stallation.
Apply compressor oil to grooves of the tube.
•After tightening, use a clean cloth to remove ex-
cess compressor oil from the connections and any
oil which may have run on the vehicle body or other
parts.
•If any leakage is suspected after tightening, do
not tighten the connections further, but disconnect
the connections, remove the O-rings, and check
the O-rings, threads, and connections.
D: PREPARATION TOOL
CAUTION:
When working on vehicles with a HFC-134a
system, only use HFC-134a specified tools and
parts. Do not mix CFC-12 tools and parts. If
HFC-134a and CFC-12 refrigerant or compres-
sor oil is mixed, it will result in poor lubrication
and the compressor itself may be damaged.
In order to prevent the mixture of HFC-134a and
CFC-12 parts and liquid, the tool and screw
type and the type of service valves used are dif-
ferent. The gas leak detectors for the HFC-134a
and CFC-12 systems must also not be inter-
changed.

0.45±0.15 mm (0.0177±0.0059 in)
2. MAGNETIC CLUTCH OPERATION
1) Disconnect the compressor connector.
2) Connect the positive (+) lead from the battery to
the compressor connector terminal, and the nega-
tive (–) lead to the compressor body.
3) Check the magnet clutch engagement.
If there is a problem, replace the compressor.
B: REMOVAL
1) Perform the compressor oil return operation.
2) Turn the A/C switch to OFF and stop the engine.
3) Using the refrigerant recovery system, dis-
charge refrigerant.
4) Disconnect the ground cable from battery.
5) Remove the V-belts.
6) Remove the generator.
7) Remove the bolt and remove the low-pressure
hose and high-pressure hose.
8) Disconnect the compressor harness from the
body harness.
