RECEIVER/DRIER-A/C
DESCRIPTION
The receiver/drier (1) stores unnecessary refrigerant,
filters the refrigerant, helps remove moisture from the
refrigerant and retains any refrigerant vapor that may
leave the A/C condenser (2) until it becomes a liquid.
The receiver/drier is installed on the high-side of the
A/C system and is connected directly to the right end
of the A/C condenser. The receiver/drier can be easily
serviced by removing the front fascia.
OPERATION
The receiver/drier performs a filtering action to prevent foreign material in the refrigerant from contaminating the A/C
expansion valve. Refrigerant enters the receiver/drier as a high-pressure, low temperature liquid. Desiccant inside
the receiver/drier absorbs any moisture which may have entered and become trapped within the refrigerant system.
In addition, during periods of high demand operation of the A/C system, the receiver/drier acts as a reservoir to
store surplus refrigerant.
The receiver/drier cannot be repaired. If the receiver/drier is faulty or damaged, or if an internal failure of the A/C
compressor has occurred, the receiver/drier must be replaced.
REMOVAL
WARNING: Refer to the applicable warnings and cautions for this system before performing the following
operation (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - WARNINGS) and (Refer to 24 - HEAT-
ING & AIR CONDITIONING/PLUMBING - CAUTIONS). Failure to follow the warnings and cautions could result
in possible personal injury or death.
1. Recover the refrigerant from the refrigerant system
(Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING
-
STANDARD
PROCEDURE
-
REFRIGERANT SYSTEM RECOVERY).
2. Disconnect and isolate the negative battery cable.
3. Remove the front fascia (Refer to 23 - BODY/EX-
TERIOR/FRONT FASCIA - REMOVAL).
4. Remove the screw (1) that secures the receiver/
drier mounting bracket (2) to the right end of the
A/C condenser (3).
5. Remove the bolt (4) that secures the receiver/drier
(5) to the A/C condenser.
6. Disconnect the receiver/drier from the A/C con-
denser and remove and discard the dual-plane
seal.

7. Install plugs in, or tape over the opened receiver/drier fitting and the condenser ports.
INSTALLATION
NOTE: If the receiver/drier is being replaced, add 30 milliliters (1 fluid ounce) of refrigerant oil to the refrig-
erant system. Use only the refrigerant oil of the type recommended for the A/C compressor in the vehicle.
1. Position the receiver/drier (5) into the engine com-
partment.
2. Remove the tape or plugs from the receiver/drier
fitting and the ports of the A/C condenser (3).
3. Lubricate a new dual-plane seal with clean refriger-
ant oil and install it onto the receiver/drier fitting.
Use only the specified seal as it is made of a spe-
cial material for the R-134a system. Use only
refrigerant oil of the type recommended for the A/C
compressor in the vehicle.
4. Connect the receiver/drier to the right end of the
A/C condenser.
5. Install the bolt (4) that secures the receiver/drier to
the A/C condenser. Tighten the bolt to 22 N·m (16
ft. lbs.).
6. Install the receiver/drier mounting bracket (2) onto
the A/C condenser.
7. Install the screw (1) that secures the receiver/drier
mounting bracket onto the A/C condenser. Tighten the screw to to 5 N·m (44 in. lbs.).
8. Install the front fascia (Refer to 23 - BODY/EXTERIOR/FRONT FASCIA - INSTALLATION).
9. Reconnect the negative battery cable.
10. Evacuate the refrigerant system (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD
PROCEDURE - REFRIGERANT SYSTEM EVACUATE).
11. Charge the refrigerant system (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD PRO-
CEDURE - REFRIGERANT SYSTEM CHARGE).

REFRIGERANT-A/C
DESCRIPTION
The refrigerant used in this air conditioning system 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-flammable, 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 A/C system. Even a small amount of R-12 refrigerant
added to an R-134a refrigerant system will cause A/C compressor failure, refrigerant oil sludge or poor A/C system
performance. In addition, the polyalkylene glycol (PAG) synthetic refrigerant oils used in an R-134a refrigerant sys-
tem are not compatible with the mineral-based refrigerant 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 refrigerant system is not accidentally contaminated with the
wrong refrigerant (R-12). There are also labels posted in the engine compartment of the vehicle and on the A/C
compressor to identify that the A/C system is equipped with R-134a refrigerant.
