长安福特 福克斯常见故障

1, about the fox after cold start sound: cold car starts the

engine parts produce Cha, Cha, Cha noise, frequency related to

engine speed, as the rise of the run time or engine temperature,

The sound is almost gone. New cars are more obvious.

Belt are the main reasons why: because the fox is multi slot

cog-type belt, new belt surface of the rubber is soft, when the

vehicle parked at low temperature after a long time, the belt

on the pulley of the contact

Will have deformation, once in motion, the deformation of the

other variant parts by different resistance during operation,

when the belt groove will cause some noise, when the runtime

After a little longer, the sound disappears due to the softening

of the belt, which is normal. In addition, if you have a few

grains of sand in your belt, you will have constant noise

It takes a long time to run, and when you look at the belt trough,

you will find that there are sand grains in the belt slot, and

the general use is not too much of an impact, and it can be solved

by removing it. The fox air conditioner belt is due

This phenomenon occurs at the bottom of the engine.

Fox started the engine room with a \"sizzling\" sound:

Why: most of it is the electronic steering pump sound. It is

designed to provide high oil pressure (high speed of oil pump) when driving at low speed, and low when driving at higher speed

Oil pressure, so the high frequency sound of turning the pump

at idle speed is larger. This is normal.

If the cab can hear clear \"zi zi\", probably because of the

booster pump installation causes: pump body, pipeline on the

vehicle body, for example, will be shaking voice

At the end of the day, the noise will be eliminated by adjusting

the position of the pump and line. This is often seen after the

car is repaired.

When the cold car is idle, the clutch pedal is lifted from the

gap, and there is a sound, and when you step on the clutch the

voice is not:

Why: we found that there were two reasons:

It is caused by the gap between the spline shaft and clutch in

the clutch. When the car starts in the morning or in a cold car,

start

Machine operation is not smooth, because of the resistance is

big, each work cycle speed change), causes the engine output

rotation speed of jitter (normal), to the clutch plate,

Due to the damping spring clearance and clutch plate, lead to

have a little noise, once the engine, engine speed smooth

operation, the noise is small (not).

2. Due to the structure of the clutch wheel cylinder is set on

the transmission input shaft sleeve, is to rely on the clutch

pressure plate by separating bearings provide cylinder return

force, so usually release bearing

It is always in contact with the pressure plate, and sometimes

it creates a sound when it is slightly touched. The reason for

the gap between the shaft sleeve of the clutch blade is the

clearance and wear (not affected).

So when you are driving, you should be careful not to make a

big impact on the clutch, especially in low gear.

The fox manual is a \"hum -\" noise in the semi-disconnection.

Cause: the vibration noise of the clutch. The clutch plate is

placed between the clutch pressure plate and the flywheel. The

reason is that the friction surface of the clutch plate is

smoother and then the clutch plate /

In the friction of the flywheel, the vibration of the clutch

is caused by noise. The structure of the clutch is a steel

corrugated lining in the friction between the two sides,

providing a variable for the separation process

Torque transfer. Once the friction and vibration of the

disconnecting process cause the vibration of the lining and

clutch friction, the noise will be generated. The occurrence

of noise usually indicates

The wear of the clutch is more serious, Sometimes you can smell the clutches of the clutch when you go

to the service station, so try to minimize the wear and tear

of the clutch.

Reduce the state of a semi-disconnecting drive.

We all know that fox started off with an engine that was more

difficult to control, and it often started off. But if you start

off with too much gas, it will make the engine

Speed is too high, will add to the clutch plate wear, so it\'s

best to start speed control within 1200 ~ 1400, and control the

throttle when the shift and the shifting speed.

Often occurs when the car started out the car, or in engine under

normal temperature, engine have a gap, empty after the gas lift,

speed decreased to 5 ~ 600 r/min and then rise to

The normal idle speed 7 ~ 800 turn/minute phenomenon, need to

clean the throttle door as soon as possible. In fact, after

cleaning the throttle and making the computer clean, you can

start off the throttle completely

Not go out.

5, winter driving instrument will be issued from time to time

\"di\" sound: this is due to the outdoor temperature found 4

degrees Celsius temperature monitoring system, 0 degrees

Celsius when prompt! Alert driver

The danger of icy roads. If it is near zero degrees Celsius,

ambient temperature changes are more frequent, and the prompt

is more likely to occur.

The sound of air conditioning in summer: this may be the sound

of air conditioning pump working, normally normal phenomenon.

Because of the hot weather, the air conditioning system has a

heavy workload and low speed

Degrees, the air conditioning system high side pressure is big,

the operation of air conditioning pump noise nature is larger,

if there is no abnormal noise, such as the problem of bearing

abnormal noise in the noise, pump, is normal. Slide in the

process of vehicle running space, usually could hear the sound

of the some air conditioning pump, such as close the a/c switch,

sound disappear immediately, can determine the voice of air

conditioning pump. If it\'s cooler in the weather, the pump\'s

voice will be relatively small.

There is a different starting point of the automatic

transmission: it is normal to lift the brakes. This is because

the wheels have a tendency to roll forward, when the brakes are

lifted, brake pads and brake pads

start

When there is relative motion, and is, to some extent, under

the action of braking force will emit sound, this is most of

the automatic transmission car (as long as it is lift brake

automatically go car) will be out

The phenomenon is very normal. If you don\'t want it to ring,

just hang the gear in the n gear, lift the brakes (note not the

car), and then hang the d, and there will be no sound.

Fox easily has a different place:

Indoors: the front panel and the cosmetic mirror light switch.

The back door is loose and the door has a \"creak\" on the side

of the door. Reposition the head pillow to adjust the guard

sleeve. The trunk is caused by clutter

Sound; Seat sound; The solution can be adjusted separately.

Outdoor: when the engine is cooled, the thermal expansion

factor of different metal materials will be \"flopper\". The

normal sound of the sound; Tire noise (normal road noise); The

road

A pebble on the surface of a tyre causes the sound of hitting

the pavement. The larger exhaust noise of a cold car; The

resonance of the iron substrate; The resonant and protective

plate of the protective plate under the tank

The noise of the upper foreign body; Cross stabilizer friction

ring with horizontal stabilizer; Transverse stabilizer Shock

absorber/gel ring; Engine/gearbox overhang.

The gap between the transmission system; The brake system is

different; The vibration of the fender is fixed and loose. The

noise of the wind and the noise of the door. Sunroof wind noise;

Outside the car reflector; The engine shields are all together Vibration noise. Engine cover resonance noise; And

so on.

Sometimes you need to determine sound comes from the engine,

transmission, or driving system, it can be through the

different gear, speed, speed will distinguish, if need

maintenance check,

It is best to be clear about the timing and the road conditions,

avoiding duplication and delay. It is best to have a warmer

weather when it happens and doesn\'t affect the safety of the

car

To repair, this avoids the other problems caused by low

temperature, poor plastic parts, and multiple disassembly.
