NOTE: Be certain to check the refrigerant oil level if
the A/C compressor is being replaced. See Refriger-
ant Oil Level in this group for the procedures. Use
only refrigerant oil of the type recommended for the
A/C compressor in the vehicle.
NOTE: If an internal failure of the A/C compressor
has occurred, the receiver/drier must be replaced.
(1) Position the A/C compressor in the engine com-
pa rtmen t and loosely install the thr ee com pr essor
reta ining bolts. Tighten th e bolts using the following
sequence to 20 N·m (14 ft. lbs.).
• Th e upper bolt at the front of t he compr essor.
• Th e lower bolt at t he fron t of the compressor.
• Th e bolt a t the r ear of th e compressor.
(2) Remove the tape or plugs from the opened
underbody suction a nd disch arge line fit tings and
compressor ports.
(3) Lubricate new rubber O-r ing seals wit h clea n
refriger ant oil and install them onto t he suct ion and
the discharge line fittings. Use only the specified

(4) Connect the under body suct ion an d dischar ge
lin es to th e A/C compressor.
(5) In st all the bolts tha t secure t he underbody suc-
tion and dischar ge lines to the A/C compr essor.
Tighten t he bolts to 21 N·m (15 ft. lbs.).
(6) Connect the wir e ha rness conn ector to the A/C
compressor clu tch coil.
(7) In st all the accessor y drive belt (Refer to 7 -

(8) Lower th e vehicle.
(9) Replace the receiver /dr ier if t he A/C compressor
is being r eplaced due t o an in ternal failur e (Refer to
24 - HE ATING & AIR CONDITIONING/P LUMBING/
RECEIVE R/DRIER - REMOVAL) and (Refer to 24 -

A/CCONDENSER
DESCRIPTION
The condenser is located in the air fl ow in fr ont of
the en gin e cooling ra diat or. The con denser is a h eat
excha nger tha t allows the high-pressure r efrigera nt
gas bein g dischar ged by the compr essor t o give up its
heat t o the air passin g over the condenser fins.
OPERATION
When t he refrigera nt gas gives up it s heat , it con-
denses. When th e refrigerant leaves the con denser, it
has become a high-pr essu re liquid refrigerant. The
volu me of a ir flowing over t he conden ser fins is crit -
ical to th e proper coolin g per formance of the air con-
ditionin g syst em. Therefor e, it is important that
