pipes and joints at the low pressure end. Touch the high pressure area, especially the metal parts at

the high pressure end, such as compressor’s exhaust pipe, condenser, stock fluid dryer and etc, and

find these sections are hot. Be care! If you touch these positions and find that your hand is hot but

doesn’t feel burning, it is normal; and if your hand feels hurning, check whether the condenser is in

the good cooling conditio, the surface of condenser is clean without foreign materials, and etc.

If your hand feels that the temperature is not high at the high pressure end, it indicates that the

coolant level is low; and if there is no temperature which can be felt by your hand, it indicates that

the coolant fully leaks.

If the frosting symptom or water dews can be found on the fluid reservoir, it indicates that the

dessicant is broken and blocks the pipe from which the coolant flows and the temperature of high

pressure area at the front end of this reservoir is very high. In this case, solve the clogging problem

A.S.A.P, replace it with a new dryer and clean the system at the same time.

The temperature of the expansion valve is special when you feel it by hand: its coolant inlet joint is

hot while its outlet joint is cold, with some water dews. If the frosting symptom is found at the

outlet of the expansion valve, it indicates that the expansion valve port is clogged. It may be caused

due to either the foreign materials or the ice generated by the moisture which enters into the cooling

system. The trouble must be handled immediately: either clean the system, replace it with a new

dryer and expansion valve, or revacuumize it and remove the moisture.

Touch the low-pressure reservoir and find your hand feels cold, with water dews but without

frosting symptom. If there is the frosting symptom, it indicates that the system has trouble. Find out

the reason. Touch the intake and exhaust pipes of the compressor, and find that the temperature your

hand feels shall be considerably different. If not, it indicates that the coolant has fully leaked; and if

the difference is not big, it indicates that the coolant level is low.

IMPORTANT: When the A/C system is touched by hand, absolutely pay more attention to the

safety, and avoid the injured by the belt and other motion parts.

Fourth, check:

1. Check the tensile force of belt first. The tensile force of new and old belts is different. Even if it is

a new belt, its tensile force may also change considerably after the use of 5 minutes. As a

newly-installed belt, it must be regulated twice: After the first installation of the belt, its tensile

force must be regulated to the specified value; and after it operates for 30 minutes, it must be

regulated for the second time.

2. Check the magnetic clutch

3. Check the A/C blower

4. Check the high/low pressure switch and overheat protector

5. Check the heating system

6. Check the expansion valve

With the check above-metioned, make certain that the A/C system is in good working condition.

24. Check and Replacement of Three Filters

The three filters means the air cleaner, oil cleaner, and gasoline filter. These three filters are checked

and replaced as follows:

Air cleaner

Remove two screws as shown in the figure below with a cross screwdriver, take off the element of

air cleaner and then replace the element, and then reinstall the air cleaner after the replacement of

the element.

Engine oil filter

Fully drain out the engine oil, and then remove and replace the filter with a special oil filter spanner.

To ensure the sealing effect, it is best to appropriately apply a little of engine oil on the screwed end

of the new oil filter, and then reinstall it.

Fuel filter

Remove the bolts as shown in the figure below, take off the clamp from the gasoline filter, and then

remove the oil pipe joints from the both extremes, install a new gasoline filter in the reverse order.

25. Four-Wheel Alignment Check

Please refer to Service Manual For Chassis, and check the four-wheel alignment parameters with a

four-wheel alignment machine according to the parameters listed in the table below. If not

26. Lamp Check

26.1. Position Lamp:

Shift the headlamp switch on the instrument panel to the 1

st

gear position, i.e., the clearance

lamp position. In this case, the front and rear position lamps, and number plate lamp are turned

on at the same time. And, after the clearance lamp turns on, all nightlights of instrument, audio,

air conditioner, switch and etc light; and the interior backlight can be adjusted by manipulating

the nightlight regulating switch.

26.2. Low beam lamp:

After the clearance lamp turns on, if the low beam lamp switch turns on, the low beam lamp

shall light;

26.3. High beam lamp:

If the high beam lamp switch turns on, the high beam lamp shall light, and the instrument shall

display the symbol of high beam lamp at the same time;

Fog lamp:

The front fog lamp can turns on only after the clearance lamp turns on, and the rear fog lamp

can turns on only after the front fog lamp turns on;

26.4. Turn signal lamp:

A. In case that the left turn signal lamp turns on, all the left front/left/left rear turn signal

lamps shall light at the same time;

B. In case that the right turn signal lamp turns on, all the right front/right/right rear turn signal

lamps shall light at the same time;

26.5. Hazard waring light:

In case that the warning light switch turns on, six turn signal lamps shall light at the same time,

and the warning light switch flashes, the left and right turn signal indicator lights on the

instruement panel shall flash;

26.6. Stop lamp:

In case that the stop lamp switch is stepped on, the stop lamp and high mount stop lamp shall

light at the same time;

26.7. Rear luggage compartment light:

In case that the rear luggage compartment opens, this light shall light;

26.8. Door lamp:

After the door opens, the door contact switch turns on, and then the door lamp shall light.
