Condenser
Condenser
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.

(See page AC-8)
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.

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.

Adjustment of engine cover
Remark
as the centering bolt are used as the fixing bolt to fix the
hinge of engine cover, the engine cover cannot be adjusted when
mounting, in such case, the bolt with a washer should be used to
substitute the centering bolt.
1. Adjust the engine cover in front-back and right-left
direction.
Loosen the hinge bolts on engine cover to adjust the engine
cover.
2. Adjust the engine cover leading edge vertically;
Rotate the buffer block to adjust the engine cover.
