INSTALLATION
NOTE: The A/C liquid line is serviced in two sec-
tions. The front section connects between the A/C
condenser and the receiver/drier and includes the
high side service port and the A/C pressure trans-
ducer on the fitting for the receiver/drier. The rear
section connects between the receiver/drier and the
A/C expansion valve.

RECEI V ER / DRI ER
DESCRIPTION
The receiver/drier is mou nted in a bracket secured
to th e left front stru t tower in t he engine compar t-
ment . The receiver /dr ier is connect ed between th e
front and r ear sections of the A/C liqu id line between
the con denser outlet and t he evaporator inlet.
The receiver/drier can not be r epair ed. If th e receiv-
er/drier is faulty or dam aged, or if the r efrigera nt
system ha s been contamina ted or left open to the
atmosphere for an indet erminable period or if th e
compressor ha s fa iled, it must be repla ced.
OPERATION
The receiver/drier perform s a filter ing act ion to
pr event foreign material in the refriger ant from con-
taminat ing th e A/C expansion valve. Refriger ant
enters th e receiver/drier a s a h igh -pressu re, low tem-
perat ure liqu id. Desiccan t inside the r eceiver/drier
absorbs any moistur e which m ay have en tered and
become tra pped within the refr iger ant syst em. In
addition, during periods of high dem and operation of
the A/C system, th e receiver/drier acts a s a reservoir
to stor e surplus refr iger ant.
