4. O-ring Connections
1. GENERAL
The following points should be kept in mind when assem-
bling O-ring connections.
1) Avoid unnecessary handling and contact of O-rings with
your hands, since even clean fingers contain body acids,
which can contaminate the O-ring surface.
2) Do not handle O-rings with gloves, shop towels, etc.,
since lint particles may cling to the O-ring, possibly caus-
ing a leak upon assembly.
3) Always lubricate O-rings before assembly to allow the
O-ring to seat itself properly.
4) Be certain to use torque wrenches when tightening
O-ring fittings, because overtightening can not only dam-
age the O-ring, but it can distort the tube end as well.
G4M0581
2. REMOVE PROTECTIVE SEALS
Just prior to making the connection, remove the protective
seals.
CAUTION:
If for any reason you have to stop before making a
connection, recap the tube, component or fitting.
G4M0582
Visually inspect the O-ring surface, the O-ring mating
surface, the threads and the connection points. If a defec-
tive part is found, replace it.
The O-ring must sit square against the tube bead. If
necessary, slide the O-ring into proper positionwith clean
hands.

3. LUBRICATE THE COMPONENTS
For lubrication of the components, use only refrigerant oil
as described in the appropriate service manual. Apply oil
from an oil squirt gun or other closed container. Do not use
your finger to spread the oil over the O-ring.
Apply a small amount of refrigerant oil to the top and sides
of the O-ring. The area covered by oil should include the
O-ring and the tube bead.
G4M0584
4. TORQUE THE FITTING
Using a back-up wrench in conjunction with a calibrated
torque wrench, torque the connection to the midrange of
the specification.
After completion of torquing, use a clean shop towel to
remove any excess oil from the connection or any oil that
may have dripped on the vehicle body or other parts.
CAUTION:
If a leak is suspected after torquing, do not retighten
or retorque the connection. Instead, disassemble the
connection, remove the O-ring, and inspect the O-ring,
threads, joints and seating surfaces.

3) Disconnect the connection between the expansion
valve and pipe from receiver drier.
4) Remove the expansion valve from pipes.
5) To install expansion valve, reverse removal procedures.
Properly wrap capillary tube of expansion valve with seal.
6) Check to see if the evaporator fins are clogged. If they
are, clean them with compressed air.
CAUTION:
Water must never be used to clean the evaporator.
7) Check parts that have been removed for cracks or
scratches, and repair or replace them with new ones, if
necessary.
8) Reassemble the evaporator in the reverse order of dis-
assembly.
NOTE:
Confirm that the O-ring is inserted in the specified position.
