PLUMBING
RECEIVER/DRIER
DESCRIPTION
The receiver/drier is mounted in a bracket secured
to the left front strut tower in the engine compart-
ment. The receiver/drier is connected between the
front and rear sections of the liquid line between the
condenser outlet and the evaporator inlet. The receiv-
er/drier cannot be repaired. If the receiver/drier is
faulty or damaged, or if the refrigerant system has
been contaminated or left open to the atmosphere for
an indeterminable period or if the compressor has
failed, it must be replaced.
OPERATION
The receiver/drier performs a filtering action to
prevent foreign material in the refrigerant from con-
taminating the expansion valve. A desiccant bag is
mounted inside the receiver/drier canister to absorb
any moisture which may have entered and become
trapped within the refrigerant system. In addition,
during periods of high demand air conditioner opera-
tion, the receiver/drier acts as a reservoir to store
surplus refrigerant. Refrigerant enters the receiver/
drier as a high-pressure, low-temperature liquid.
REMOVAL
WARNING: REVIEW THE WARNINGS AND CAU-
TIONS IN THE FRONT OF THIS SECTION BEFORE
PERFORMING THE FOLLOWING OPERATION (Refer
to 24 - HEATING & AIR CONDITIONING/PLUMBING -
WARNING) and (Refer to 24 - HEATING & AIR CON-
DITIONING/PLUMBING - CAUTION).
(1) Recover the refrigerant from the refrigerant
system(Refer to 24 - HEATING & AIR CONDITION-
ING/PLUMBING - STANDARD PROCEDURE).
(2) Remove the bolts that secure the front and rear
sections of the liquid line to the top of the receiver/
drier (Fig. 15).
(3) Disconnect the liquid line fittings from the
receiver/drier.
(4) Remove the seals from the liquid line fittings
and discard.
(5) Install a plug in, or tape over the opened liquid
line fittings and the receiver/drier ports.
(6) Loosen the clamp that secures the receiver/
drier to the mounting bracket.
(7) Remove the receiver/drier from the engine com-
partment.

INSTALLATION
NOTE: If the receiver/drier is being replaced, add 30
milliliters (1 fluid ounce) of refrigerant oil to the
refrigerant system. Use only refrigerant oil of the
type recommended for the compressor in the vehi-
cle.
(1) Position the receiver/drier onto the mounting
bracket on the front left strut tower.
(2) Tighten the clamp that secures the receiver/
drier to the mounting bracket.
(3) Remove the tape or plugs from the liquid line
fittings and the receiver/drier ports.
(4) Lubricate new rubber O-ring seals with clean
refrigerant oil and install them on the liquid line fit-
tings.
(5) Connect the front and rear sections of the liq-
uid line to the receiver/drier.
(6) Install the bolts that secures the liquid line fit-
tings to the receiver/drier. Tighten the bolts to 7 N·m
(62 in. lbs.).
(7) Evacuate the refrigerant system (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING -
STANDARD PROCEDURE - REFRIGERANT SYS-
TEM EVACUATE).
(8) Charge the refrigerant system (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING -
STANDARD PROCEDURE - REFRIGERANT SYS-
TEM CHARGE).
