6. REFRIGERANT OVERCHARGE OR INSUFFICIENT COOLING OF CONDENSER
Symptom seen in
refrigeration systemProbable causeDiagnosisRemedy
(1) Clean condenser
(2) Check fan motor
operation
(3) If (1) and (2) are in
normal state, check
amount of refrigerant
Charge proper amount

Pressure too high on both
low and high pressure
sides

No air bubbles seen
through the sight of glass
even when the engine
rpm is lowered.

(1) Check compressor oil to
see if dirty or insufficient
(2) Evacuate air and charge

RECEIVER
ON±VEHICLE INSPECTION
1. OPEN THE HOOD
2. INSPECT SIGHT GLASS AND FITTING FOR LEAKAGE
Using a gas leak tester, check for leakage, check for leakage.
If there is leakage, check the tightening torque at the joints.
RECEIVER REMOVAL
1. OPEN THE HOOD
2. DISCHARGE REFRIGERANT IN REFRIGERATION
SYSTEM
INSTALLATION HINT: Evacuate air from refrigeration sys-
tem.
Charge system with refrigerant and inspect for leakage of re-
frigerant.
Specified amount:
700 +50 g (24.96 +1.76 oz.)
3. REMOVE FRONT BUMPER
(See page BO±8)
4. REMOVE RADIATOR SUPPORT UPPER SEAL
Remove the 12 clips and radiator support upper seal.
5. REMOVE LIQUID TUBES FROM RECEIVER
Remove the 2 bolts and both tubes from the receiver.
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf
INSTALLATION HINT: Lubricate the new O±rings with com-
pressor oil and install the tubes.
6. REMOVE RECEIVER
Remove the holder bolt and pull the receiver upward from the
receiver holder.
REMOVAL NOTICE: Cap the open fitting immediately to
keep moisture out of system.
INSTALLATION HINT: If receiver was replaced, add com-
pressor oil to the compressor.
Add 10 cc (2.9 fl.oz.)
Compressor oil:

ON±VEHICLE INSPECTION
1. CHECK QUANTITY OF GAS DURING REFRIGERATION
CYCLE
2. INSTALL MANIFOLD GAUGE SET
3. RUN ENGINE
Run the engine at 1,500 rpm for at least 5 minutes. Then
check that the high pressure reading is 1.371.57 MPa (14±16
kgf/cm
2, 199±228 psi).
4. CHECK EXPANSION VALVE
If the expansion valve is faulty, the low pressure reading will
drop to 0 kPa (0 kgf/cm
2, 0 psi).
HINT: When the low pressure drops to 0 kPa (0 kgf/cm
2, 0
psi), feel the receiver's IN and OUT sides for zero tempera-
ture difference.
EXPANSION VALVE REMOVAL
1. REMOVE EVAPORATOR
(See page AC±82)
2. REMOVE EXPANSION VALVE
Using a hexagon wrench, remove the 2 bolts and separate
the evaporator and expansion valve.
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf)
INSTALLATION HINT: Lubricate the new O±ring with com-
pressor oil and install the tubes.

GENERAL REPAIR INSTRUCTIONS
1. Use fender, seat and floor covers to keep the vehicle
clean and prevent damage.
2. During disassembly, keep parts in the appropriate order
to facilitate reassembly.
3. Observe the following:
(a) Before performing electrical work, disconnect the
negative cable from the battery terminal.
(b) If it is necessary to disconnect the battery for inspec-
tion or repair, always disconnect the cable from the
negative (-) terminal which is grounded to the ve-
hicle body.
(c) To prevent damage to the battery terminal post, loos-
en the terminal nut and raise the cable straight up
without twisting or prying it.
(d) Clean the battery terminal posts and cable terminals
with a clean shop rag. Do not scrape them with a file
or other abrasive objects.
(e) Install the cable terminal to the battery post with the
nut loose, and tighten the nut after installation. Do
not use a hammer to tap the terminal onto the post.
(f) Be sure the cover for the positive (+) terminal is prop-
erly in place.
4. Check hose and wiring connectors to make sure that they
are secure and correct.
5. Non-reusable parts
(a) Always replace cotter pins, gaskets, O-rings and oil
seals etc. with new ones.
(b) Non-reusable parts are indicated in the component
illustrations by the ºº symbol.
6. Precoated parts
Precoated parts are bolts and nuts, etc. that are coated
with a seal lock adhesive at the factory.
(a) If a precoated part is retightened, loosened or
caused to move in any way, it must be recoated with
the specified adhesive.
(b) When reusing precoated parts, clean off the old
adhesive and dry with compressed air. Then applyIN022-02
