(1) Position the accumulator into the engine com-
partment.
(2) Install and tighten the screw that secures the
accumulator mounting bracket to the right side rail.
Tighten the screw to 11.3 N·m (100 in. lbs.).
(3) Remove the tape or plugs from the accumulator
connector block inlet and outlet ports and the refriger-
ant line fittings of the suction and liquid line assembly.
(4) Lubricate new rubber O-ring seals with clean
refrigerant oil and install them on the refrigerant
line fittings of the suction and liquid line assembly.
Use only the specified O-rings as they are made of a
special material for the R-134a system. Use only
refrigerant oil of the type recommended for the com-
pressor in the vehicle.
(5) Reconnect the refrigerant line fittings of the
suction and liquid line assembly to the accumulator
connector block inlet and outlet ports.
(6) Install and tighten the two screws that secure
the two refrigerant line fittings of the suction and
liquid line assembly to the accumulator connector
block inlet and outlet ports. Tighten the screws to 2.3
N·m (20 in. lbs.).
(7) Reinstall the low pressure clutch cycling switch
onto the accumulator(Refer to 24 - HEATING & AIR
CONDITIONING/CONTROLS/A/C LOW PRESSURE
SWITCH - INSTALLATION).
(8) If the vehicle is so equipped, reinstall the vehi-
cle speed control servo(Refer to 8 - ELECTRICAL/
SPEED CONTROL/SERVO - INSTALLATION) or
(Refer to 8 - ELECTRICAL/SPEED CONTROL/
SERVO - INSTALLATION).
(9) Reconnect the battery negative cable.
(10) Evacuate the refrigerant system(Refer to 24 -
HEATING & AIR CONDITIONING - STANDARD
PROCEDURE).
NOTE: If the accumulator is replaced, add 89 milli-
liters (3 fluid ounces) of refrigerant oil to the refrig-
erant system. Use only refrigerant oil of the type
recommended for the compressor in the vehicle.
(11) Charge the refrigerant system(Refer to 24 -
HEATING & AIR CONDITIONING - STANDARD
PROCEDURE).
CONDENSATION DRAIN TUBE
DESCRIPTION
Condensation that accumulates in the evaporator
housing is drained by a tube through the dash and
on to the ground. This tube must be kept open to
prevent condensate water from collecting in the bot-
tom of the housing.
The tapered end of the drain tube is designed to
keep contaminants from entering the heater A/C unit
housing. If the tube is pinched or blocked, condensate
cannot drain, causing water to back up and spill into
the passenger compartment. It is normal to see con-
densate drainage below the vehicle. If the tube is
damaged, it should be replaced.
REMOVAL
(1) Raise vehicle on a suitable lift.
(2) Locate rubber drain tube on right side of dash
panel under the hood (Fig. 54).
