Inspection On Refrigerant Quantity
Inspection on Refrigerant Quantity
1. Run the engine at the speed of 1500 r/m or so (the
atmospheric temperature should be above 35
);
2. Start the air-conditioner in the max cold air status for
several minutes;
3. Check the refrigerant quantity.
Watch the observation window on liquid tank.

Symptoms
Refrigerant quantityRepairing approaches
Air bubble occurs in the observa-
tion window
No air bubble in observation win-
dow
No temperature difference between
the inlet and outlet of compressor
Obvious temperature difference be-
tween the inlet and outlet of compressor.
Observation window is in clear status
once the air-conditioner is turned off
There is refrigerant foam on observa-
tion window after the air-conditioner
is turned off, then the observation
window becomes clear.Insufficient

NormalCheck to see whether there is leakage with the
gas leakage detector
Refers 3 and 4.
Vacuumize the system and inflate the
refrigerant, then check to see whether there is
leakage with the gas leakage detector.
Refer 5 and 6
Exhaust the redundant refrigerant until the speci-
fied quantity is satisfied.

On-vehicle inspection on expansion valve
1. Check the gaseous refrigerant quantity in the refrigeration
cycle;
2. Mount the manifold gauge;
(see Page AC-12)
3. Run the engine;
Run the engine at a speed of 2000 r/m for five minutes.
4. Check the expansion valve;
If the expansion valve is blocked, the LP readings will reduce
to 0 kPa, otherwise, the valve is normal.
Disassembly of Refrigeration Device
1. Disconnect the cathode lead from the storage cell;
2. Exhaust the refrigerant;
3. Tear down the suction pipe from the entrance joint of
refrigeration device;
4. Tear down the outlet pipe from the entrance joint of
refrigeration device;
Remark: the opened joint should be sealed with the cork to
prevent the humid air from entering into the system.
5. Tear down the insulation rings from the inlet and outlet
joints.
6. Tear down the right glove box (SY rear air-conditioner:
tear down the interior trim panel at left rear side).
7. Disconnect the plugging element;
8. Tear down the refrigeration device;
Tear down the three nuts.

inspectionofevaporator
1. Check the radiating ribs of evaporator to see whether there is
block.
If the radiating rib is blocked, clean it with the compressed air.
Notice: do not wash the evaporator with water.
2. Check the joint to see whether there is crack or scrape.
Make reparation as requirement.
Mount the evaporator parts:
(a) Connect the expansion valve to the entrance joint of evaporator
and screw up the nuts.
Remark: Carefulness should be put on the O-ring seal.
(b) Mount the bracket on the suction pipe with thermal sensor;
(c) Connect the liquid pipe to the entrance joint of expansion
valve and screw up nuts.
(d) Mount the lower cluster housing on evaporator.
(e) Mount the upper cluster housing;
(f) Mount the four screws;
(g) Mount the two clipes;
(h) Mount the HP/LP pressure rubber washer; and
(i) Connect the plugging elements;
1. Mount the refrigeration device.
Mount the refrigeration device with three nuts.
2. Connect the plugging elements;
3. Mount the right glove box (SY rear air-conditioner: mount the
interior trim panel at left rear side).
4. Mount the insulation ring on the inlet and outlet joints;
5. Connect the liquid pipe to the outlet joint of refrigeration device;

(see page AC-8)
7. Connect the cathode lead to the storage cell.
8. Vacuumize the air-conditioning system:
Vacuumizing time:
Dr SL SK SF SJ
vacuumize for 20min and maintain the
pressure for 30min
SY: vacuumize for 30min and maintain the pressure for
another 30min.
9. Inflate the refrigerant in the air-conditioning system and
check to see whether there is air leakage;
