Overhaul
1.
3.
Pull out the A,/C thermostat sensor from the evapo-
rator fins.
Remove the self-tapping screws and clamps from
the housings.
Carefully separate the housings, then remove the
evaporator.
lf necessary, remove the expansion valve.
NOTE: When loosening the expansion valve nuts, use
a second wrench to hold the expansion valve or the
evaporator pipe. Otherwise, they can be damaged
5. Assemble in the reverse order of disassembly Make
note of following items.
. Replace the O-rings with new ones at each fitting,
and apply a thin coat of refrigerant oil before
installing them.
NOTE: Be sure to use the right O-rings for HFC-
134a (R-134a) to avoid leakage.
. Install the expansion valve capillary tube so that
it is in direct contact with the suction line. Then
wrap wath taPe.
. Reinstall the Ay'C thermostat sensor to its original
location.

10. lnstall in the reverse order of removal. Make note of
the following items.
. lf you're installing a new compressor, drain all
the refrigerant oil from the removed compressor,
and measure its volume. Subtract the volume of
drained oil from '130m? 14 1/3 tl'o2,4 6 lmp'oz);
the result is the amount of oil you should drain
from the new compressor (through the suction
fifting).
. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat of refrigerant oil
before installing them
NOTE: Be sure to use the right O-rings for HFC-
134a (R-134a) to avoid leakage
. Use refrigerant oil (SP-10) for R-134a Sanden and
Hadsys spiral type compressors only'
o To avoid contamination, do not return the oil to
the container once dispensed, and never mix it
with other refrigerant oils.
. lmmediatelY after using the oil, replace the cap
on the container, and seal it to avoid moisture
absorption.
. Do not spill the refrigerant oil on the vehicle; it
may damage the painu if the refrigerant oil con-
tacts the paint, wash it off immediately
. Adjust the Ay'C compressor belt (see page 22-43)
and the power steering pump belt (see section 17)'
. Charge the system (see page 22-46), and test its
oerformance (see Page 22-241

lf you're installing a new compressor. drain all therefrigerant oil from the removed compressor. andmeasure its volume. Subtract the volume ofdrained oil from '140 ml (4 28 fl{,z, 4.9 lmpoz); theresult is the amount of oil you should drain fromthe new compressor (through the suction fifting).Replace the O-rings with new ones at each fining,and apply a thin coat of refrigerant oil beforeinstalling them. Be sure to use the right O,ringsfor HFC-134a (R-134a) to avoid leakage.
Use refrigerant oil {DENSO, ND-OtL8) for HFC-134aDENSO piston type compressors only.To avoid contamination, do not return the oil tothe container once dispensed, and never mix itwith other refrigerant oils.
lmmediately after using the oil, replace the capon the container, and seal it to avoid moisture
absorption.
Do not spill the refrigerant oil on the vehicle; itmay damage the paint; if the refrigerant oil con-tacts the paint, wash it off immediatelv.
Adjust the ly'C compressor belt (see page 22-43)and the power steering pump belt (see section 17).Charge the system (see page 22-46), and test itsperformance (see page 22-24!..

Fuel Gauge
Gauge/Sending Unit Test
!@ Do not smoke while working on tho fuel
system. Keep open tlame away trom your wotk atea.
NOTE: Refer to page 23-133 for the fuel gauge system
circuit.
'1. Check the No. 25 (7.5 A) fuse in the under-dash fuse/
relay box before testing.
2. Remove the access panel from the floor.
ACCESS PANEL
Disconnect the 3P connector from the fuel gauge
sending unit.
Connect the voltmeter positive probe to the No. 2
terminal and the negative probe to the No. I termi-
nal, then turn the ignition switch ON (ll).
There should be between 5 and 8 V.
. lf the voltage is as specified, go to step 5.
. lf the voltage is not as specified. check for:- an open in the YEUBLK or BLK wire.- poor ground (G552).
Turn the ignition switch OFF.
Attach a jumper wire between the No. 1 and No. 2
terminals, then turn the ignition switch ON (ll).

23-142
1.Check that the pointer of the fuel gauge starts mov-
ing toward the "F" mark.
CAUTION: Turn the ignition switch OFF before thepoinier reaches "F" on ihe gauge dial. Failure to do
so may damage the fuel gauge.
NOTE: The fuel gauge is a bobbin (cross-coil) type,
hence the fuel level is continuously indicated even
when the ignition switch is OFF, and the pointer
moves more slowly than that of a bimetaltype.
. lf the pointer of the fuel gauge does not move at
all, replace the gauge.
. lf the gauge is OK. inspect the fuel gauge send-
ing unit.
Remove the fuel gauge sending unit as shown.

Switches
These switches move
together; the broken straight
line between them means the,
are mechanically connected.
Other types of switches are
controlled by a coil or a solid
state circuit. Unless otherwise
noted. all switches are shown
in their normal (rest) position,
with power off.
This ground symbol (dot
and 3 lines) overlapping the
component means the housing
of the component is grounded
to the car frame or to a metal
part connected to the frame.
This symbol represents
the bus inside a ground
connector. The dots I

terminals connect to.
The ground symbol (large dot)
is the connection between the
bus and metal (grounded) part
of the car.

Solid-state
Fuses
This means power is supplied

Current rating
Diodes
A rectifier diode works like a one
way valve. lt allows current to
llow only in the direction of the
arrow.
A Zener diode blocks reverse
current at normal voltages just like
a rectifier diode. At high voltages.
however, a Zener diode allows
current to f low in reverse
oo
Each "T" lerminal (ring type)
is numbered for reference and
location. A "T" terminal is
secured with a screw or bolt.
Shielding
This represents RFI
(Radio Frequency
Interference) shielding
around a wire. The
shielding is always
connected to ground.
