REFRIGERANT
DESCRIPTION
The refrigerant used in this air conditioning sys-
tem is a HydroFluoroCarbon (HFC), type R-134a.
Unlike R-12, which is a ChloroFluoroCarbon (CFC),
R-134a refrigerant does not contain ozone-depleting
chlorine. R-134a refrigerant is a non-toxic, non-flam-
mable, clear, and colorless liquefied gas.
Even though R-134a does not contain chlorine, it
must be reclaimed and recycled just like CFC-type
refrigerants. This is because R-134a is a greenhouse
gas and can contribute to global warming.
OPERATION
R-134a refrigerant is not compatible with R-12
refrigerant in an air conditioning system. Even a
small amount of R-12 added to an R-134a refrigerant
system will cause compressor failure, refrigerant oil
sludge or poor air conditioning system performance.
In addition, the PolyAlkylene Glycol (PAG) synthetic
refrigerant oils used in an R-134a refrigerant system
are not compatible with the mineral-based refriger-
ant oils used in an R-12 refrigerant system.
R-134a refrigerant system service ports, service
tool couplers and refrigerant dispensing bottles have

all been designed with unique fittings to ensure that
an R-134a system is not accidentally contaminated
with the wrong refrigerant (R-12). There are also
labels posted in the engine compartment of the vehi-
cle and on the compressor identifying to service tech-
nicians that the air conditioning system is equipped
with R-134a.
REFRIGERANT OIL
DESCRIPTION
The refrigerant oil used in R-134a refrigerant sys-
tems is a synthetic-based, PolyAlkylene Glycol (PAG),
wax-free lubricant. Mineral-based R-12 refrigerant
oils are not compatible with PAG oils, and should
never be introduced to an R-134a refrigerant system.
There are different PAG oils available, and each
contains a different additive package. The A/C com-
pressors for this vehicle are designed to use an ND-8
PAG refrigerant oil. Use only the refrigerant oil of
this type to service the refrigerant system.
OPERATION
After performing any refrigerant recovery or recy-
cling operation, always replenish the refrigerant sys-
tem with the same amount of the recommended
refrigerant oil as was removed. Too little refrigerant
oil can cause compressor damage, and too much can
reduce air conditioning system performance.
PAG refrigerant oil is much more hygroscopic than
mineral oil, and will absorb any moisture it comes
into contact with, even moisture in the air. The PAG
oil container should always be kept tightly capped
until it is ready to be used. After use, recap the oil
container immediately to prevent moisture contami-
nation.
STANDARD PROCEDURE
REFRIGERANT OIL LEVEL
When an A/C system is assembled at the factory,
all components except the compressor are refrigerant
oil free. After the refrigerant system has been
charged and operated, the refrigerant oil in the com-
pressor is dispersed throughout the refrigerant sys-
tem. The receiver-drier, evaporator, condenser, and
compressor will each retain a significant amount of
the needed refrigerant oil.
It is important to have the correct amount of oil in
the refrigerant system. This ensures proper lubrica-
tion of the A/C compressor. Too little oil will result in
damage to the A/C compressor. Too much oil will
reduce the cooling capacity of the A/C system.
It will not be necessary to check the oil level in the
A/C compressor or to add oil, unless there has been
an oil loss. An oil loss may occur due to a rupture orleak from a refrigerant line, a connector fitting, a
component, or a component seal. If a leak occurs, add
30 milliliters (1 fluid ounce) of refrigerant oil to the
refrigerant system after the repair has been made.
Refrigerant oil loss will be evident at the leak point
by the presence of a wet, shiny surface around the
leak.
Refrigerant oil must be added when a receiver/
drier, A/C evaporator, or A/C condenser are replaced.
See the Refrigerant Oil Capacities chart. When an
A/C compressor is replaced, the refrigerant oil must
be drained from the old compressor and measured.
Drain all of the refrigerant oil from the new compres-
sor, then fill the new compressor with the same
amount of refrigerant oil that was drained out of the
old compressor.

REAR DISCHARGE LINE
DESCRIPTION
The rear A/C discharge line is the refrigerant line
that carries refrigerant from the underbody discharge
line to the rear A/C condenser (Fig. 26). The rear A/C
discharge line is retained to the right quarter panel
by two plastic retaining clips.

INSTALLATION
NOTE: Be certain to add refrigerant oil if the rear
receiver/drier is being replaced. The refrigerant oil
must be drained from the old receiver/drier and
measured to determine the amount of refrigerant oil
to add to the new receiver/drier. Use only refriger-
ant oil of the type recommended for the rear A/C
compressor in the vehicle.
(1) If the rear receiver/drier is being replaced,
install the correct amount and type of refrigerant oil
into the new rear receiver/drier. Drain the old receiv-
er/drier and measure the refrigerant oil. Fill the new
receiver/drier with the same amount of new refriger-
ant oil that was drained out of the old receiver/drier.
NOTE: The rear receiver/drier is labeled with a
direction-of-flow arrow to indicate refrigerant flow
through the receiver/drier. Make sure to properly
install the rear receiver/drier in the correct direc-
tion.
(2) Position the rear receiver/drier to the rear A/C
condenser housing and install the retaining bracket
and bolt. Tighten the bolt to 25 N´m (18 ft. lbs.).
(3) Remove the tape or plugs from the rear liquid
line fitting and reservoir and receiver/drier ports.
