What s going on with the squeak of the Chevrolet Classic when it starts

Mine is Aveo, it doesn't have the same sound as you when starting the four-dimensional sub, but it seems that the front wheel has a sound when starting in gear, which is the car's self-test system. Is it because you didn't turn on the key? Let's go to the 4S store and ask for it.

Is it loud Do you analyze that it comes from the engine If the sound is like the squeak of a tricycle when it starts, it may be a lack of engine oil, how many kilometers have you run?

The tank belt is loose, or signs of aging, check it out! If you haven't changed it for more than 40,000 yuan, and it is often parked outdoors, it is recommended to replace it.

Can your steering wheel shake? Or does the steering wheel make a sound when the car shakes? Check that the bayonet of the steering wheel is properly stuck, and can you be sure that it is the sound of the steering wheel, maybe it is from the engine compartment, or maybe it is the sound of the rubber door seal rubbing.

The noise in the car is sometimes very uncertain, so pay more attention to it. I've encountered noise in the car, and when the car was jolting, I always felt a clattering sound coming from the dashboard, and sometimes I thought it was a sound coming from the center console. I went to SSSS for a test drive like you and was silent, and then I came back again, and then it got worse and worse for a while, and then I pondered it myself, and it turned out that one of the feet of the engine compartment cover was loose, and there was a gap.

If the steering wheel is confirmed, the sound won't be a big deal, but it's always uncomfortable. It is recommended that you think about it yourself and you will definitely find the sound source. It's the dashboard.

Just like the last time I watched a rider say, sometimes when crossing a bumpy road, you can clearly hear a sound near the cannon barrel dashboard, like the sound of plastic parts knocking, and a bit like the sound of firecrackers in the distance. But not all the time, sometimes there is and sometimes there is not. I was depressed that when I went to the 4S store several times to check, he didn't make a sound, so I couldn't find out, and I was very depressed.

Consider the oil problem first, if it is OK, please go to the 4S shop to see if there is a problem with the starter.

Which sound?? In fact, there are many places where there will be sound.

Summary. Hello. The reasons and solutions for the Chevrolet Breeze alarm keep ringing are as follows:

1. This is because the sensitivity of the immobilizer is too high, causing the device to sound the alarm if it feels a little vibration. Solution: First find the main unit of the immobilizer, under the steering wheel and in the guard plate under the A-pillar.

Then you can directly fine-tune the sensitivity to adjust the torque, but don't adjust it too low, otherwise the anti-theft coefficient of the car is very small. 2. It is because the circuit of the anti-theft host is faulty, and the solution: it is necessary to check and repair or replace the line of the anti-theft host in time.

Check out your friends, I hope it can help you.

How to solve the Chevrolet Le Feng alarm that keeps ringing.

During driving, the alarm sounds, and the double flash is turned on.

Good. I'll solve it for you right away.

Friend. The electronic door opening fails, and after the manual door is opened, the alarm does not stop.

Good. Solve your friend right away.

Click here to rate, thank you.

There was a typo. Friend.

Please check the knuckle, which is the inner and outer cage.

1. The Chevrolet Breeze engine has abnormal noise. Symptom description: There is a lot of abnormal noise in the engine compartment, and most people also judge it to be the abnormal noise of the engine compartment by the sound**, which is usually a metal screeching sound or a howling sound.

Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.

Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding. It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

2. The Chevrolet Lefeng gearbox has an abnormal sound. Symptom description: If there is a "rustle" sound inside the gearbox while the car is driving, and there is no more after pressing the clutch or accelerator, there will be a whistle-like sound when changing gears.

Solution: There are many transmission parts, and the reasons for the sound are also more complex. Note:

Whether it is related to a specific speed, such as some planetary teeth are more obvious around 50 km h. Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission. Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault.

If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.

3. Chevrolet music wind wear and tear has abnormal noise. Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry a little about the failure of the body.

Solution: The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to judge whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slide grease can be used, while special door attachment grease is used for lubrication of glass regulators, door locking mechanisms, handle mechanisms, etc. inside the door.

It may be the sound of the internal gears of the vehicle gearbox, this situation is more complicated and more serious, the owner needs to drive the vehicle to the repair department in time, and the overall inspection of the vehicle gearbox.

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. In the case of a turbocharged engine, there is a must be a difference between the sound and the sound of a naturally aspirated engine; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that they lack their own understanding of mechanical knowledge, so they can distinguish the abnormal noise of the car and avoid wasting time and energy.

How to identify the sound of a car:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off to reduce the sound to meet the diagnostic needs. The auscultation site should be kept quiet to minimize human interference.
