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.

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.

Check 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

(see manifold gauge mount)

2.

Run the engine at the speed of 1500 r/m or so;

3.

Check the compressor according to the following items:

(a)

The HP gauge readings under the normal system should

satisfy the specified value of (1.4-1.7)MPa , that of LP

gauge should meet the specified value of (0.15-0.2)MPa .

(b)

Whether there is abnormal sound;

(c)

Whether there is leakage at the shaft oil seal.

If any problem is found, repair or change the compressor.

between the clutch lead and the grounding lead with the

ohmn meter.

General Introduction

In case there is damage to body and/or part, protection measures

should be taken first to prevent the vehicle from damaging before

repairing them.

Example:

1.

Protection adhesive strap should be contacted on the relative

part of body when conduct the disassembling and mounting

operation.

 2.

When prizing the body parts with screwdriver or scraper, those

body parts head or the edge of screwdriver or scraper should

be wrapped with adhesive strap to prevent paint layer and the

body from damaging.

If the antirust is damaged when repairing other parts, it should be

recoated in time.

Example:

1.

In case the sealing agent, paint layer or priming coat on the

body is damaged due to peel-off or crack, etc. the correspond-

ing antirust shall be used for reparation.

2.

If the hinge or plate is loosened or torn down, the antirust

should be re-coated after repairing them.

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;
