2. If the receiver-dehydrator has been exposed to
the atmosphere for any amount of time, (more than
5 minutes), the receiver-dehydrator should be re-
placed, since the life of the dessicant is probably
expended.
3. Evacuate and charge system. Refer to CHARG-ING AND DISCHARGING SYSTEM.

AND EXPANSION VALVE. GTRemoval
1. Disconnect negative battery cable.
2. Discharge system. Refer to, DISCHARGING
SYSTEM.3. While system is discharging, remove attaching
screws and lift out luggage tray. See Figure
9B-87.Figure 98.88 Evaporator Cover Assembly and
Attaching Screws GT
Figure 98.87 Luggage Tray
4. Remove all evaporator cover screws and removecover. See Figure
9B-88.
5. Remove electrical plug connector from the resis-tor assembly and unplug blower motor connection
and remove ground wire. See Figure
9B-90.6. From underneath evaporator housing, discon-
nect two (2) drain hoses. See Figure
9B-91.
7. From under car remove 4 nuts securing

and
9B-93.8. Remove inlet and outlet pipes from evaporator
and tape closed the refrigerant lines and also the

ends of lines and inlet and outlet ports of expansion
valve.
Installation5. Install resistor assembly.
6. Install evaporator assembly into car and install
mounting bracket. See Figure

If expansion valve or refrigerant lines have been ex-
posed to
,the atmosphere for any amount of time and
moisture may have entered the valve or the system,
flush the system and install new receiver-dehydrator
or valve as necessary.7. Untape the refrigerant lines and the inlet and
outlet pipes from the evaporator and install using
new o-rings on line fittings.
Due to the possible adjustment difficulties involved
if the expansion valve is disassembled, disaisembly of
the valve is not recommended. The valve may be
cleaned by submerging it in a bath of trichlorethy-
lene, alcohol, or similar solvent. Dry by blowing iil-tered compressed air through the outlet port of the
valve. The filter screen at the inlet port may be re-
placed. Remove screen by threading a lo-32 NF
screw intp old filter screen. With a washer and a nut
on the screw arranged to work as a puller screw, hold
the body of the screw and turn the nut. Insert the
new filter screen into the inlet port and lightly tap
screen only enough to seat.
1. Install expansion valve using new o-rings during
installation. Lubricate o-rings prior to installation
using No. 525 viscosity oil.
2. Install evaporator assembly and case attaching
screws.
3. Install blower motor assembly into case and se-
cure with attaching screws.
4. Install finger guard shields and fan housing case.Figure 98-97 Refrigerant Hoses and Hose Clamps
