Liquid Tank
Liquid Tank
Check to see whether there is leakage in observation window,
fusible plug and joints;
Conduct the inspection with the gas leakage detector and, if
necessary, repair or change the liquid tank.
Dismantle of Liquid Tank
1. Exhaust the refrigerant;
2. Tear down the two liquid pipes from the liquid tank;
Remark: the opened joint should be plugged with cork so as to
prevent the humid air from entering into the system.
3. Tear down the liquid tank from the tank bracket.
Mount of Liquid Tank
1. Mount the liquid tank on the liquid tank bracket;
Remark: the cover of joint should not be take down before
connecting the pipe;
2. Connect the two liquid pipes to the liquid tank;

3. Vacuumize the system and inflate the refrigerant in;
Vacuumizing time:
Dr SL SK SF SJ
Vacuumize for 20 min and main-
tain the pressure for 30min;
SY
Vacuumize for 30 min and maintain the pres-
sure for 30min.

Condenser dismantle
1. Check the radiating ribs of condenser to see whether
there is blocking or damage;
if the radiating rib is blocked, wash it with water and dry it with
compressed air.
Notice: be careful not to damage the radiating rib;
2. Check the condenser joint to see whether there is leakage;
Make reparation as requirement;
Condenser disassembly
1. Exhaust the refrigerant;
2. Tear down the median mesh and the bonnet lock bracket;
3. Disconnect the outlet hose from the entrance joint of
condenser;
4. Tear down the liquid pipe from the outlet of liquid tank;
Remark: the opened joint should be plugged with cork so as to
prevent the humid air from entering into the system.
5. Tear down the condenser:
Tear down the two bolts.
Condenser mount
1. Mount the condenser
Screw on the two bolts so that the rubber washer contacts the
mounting flanges correctly.
2. Connect the liquid pipe to the liquid tank and the outlet
hose to the condenser.

3. Mount the median mesh and the bonnet lock bracket;
4. vacuumize the air-conditioning system;
Vacuumizing time:
Dr SL SK SF SJ
vaccumize for 20min and main-
tain the pressure for 30min;
SY
vaccumize for 30min and maintain the pres-
sure for another 30min.
5. Inflate the refrigerant in the air-conditioning system and
check to see whether there is air leakage:

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.
