What should I do if the car has an abnormal noise? What should I do if the car has abnormal noise?

Perhaps, rubber and plastic products are easy to harden in winter, and abnormal noises will occur if there is a gap in the adhesive part.

Try not to run at high speed if there is an abnormal noise, and find a professional repair shop or 4S shop for a professional inspection.

If the car has an abnormal noise, go to this 4S shop to check it, check it.

The reasons for the abnormal noise of driving are: 1. The abnormal noise of the door; 2. There is an abnormal sound in the skylight; 3. Abnormal noise in the center console; 4. Abnormal sound of the chassis. The solution to the abnormal noise of driving is:

1. Tighten the screws when the door makes an abnormal noise; 2. If there is an abnormal noise in the skylight, clean the guide rail, or replace the rubber strip; 3. Check the center console; 4. Repair the chassis. The role of car maintenance: 1. Ensure the excellent performance of the vehicle; 2. Improve driving safety; 3. Reduce engine noise; 4. Extend the service life of the vehicle.

Car maintenance items: 1. Replace engine oil, oil filter, air filter, gasoline filter; 2. Check the body and tires; 3. Check the brake system; 4. Check the damage to the chassis; 5. Check the position of the oil level.

1. There is an abnormal sound in the body.

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. Workaround:

First of all, check whether there are objects in the trunk or rear seat of the car that are not fixed, easy to roll and make sound, and exclude the noise caused by some items that are not fixed.

If you find that the friction of the door and window parts of the car causes abnormal noise, you can put rubber strips on the doors and windows or pad rubber on the friction parts, etc., which may be able to reduce or eliminate the abnormal noise, but the result is only a symptom and not a cure. If none of the above problems are found, then you must go to a regular repair shop for maintenance and troubleshooting.

2. The 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.

3. There is an abnormal sound in the gearbox.

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 more complex, so we should pay attention to whether it is related to a specific speed, such as some planetary teeth that sound at about 50km 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.

Abnormal noise**1: storage compartment. I believe that most car owners do not have the habit of tidying up the storage compartment, the car has not been sorted out for several years The storage compartment must be full of messy items, so that no matter where the car is driving, as long as the engine opens the storage compartment The items in the compartment will follow the engine "beating", and the abnormal noise you hear is likely to be the vibration of the storage compartment.

In fact, it is very simple, everyone only needs to observe that when the speed increases, the louder the sound, it proves that the car transmission system is faulty. The most effective solution is to see if the car tires have a puncture, if there is, it is recommended that you go to a regular car 4S shop for maintenance.

Abnormal noise**3: abnormal noise outside the car. If the abnormal noise heard is from outside the car, we should first look at whether the doors and windows of the car are normal, and at the same time see if there are things in the trunk.

In addition, you should also check whether there is any debris around the wiper, and clean it up in time if there is one, so as not to affect the normal use of the wiper.

You must know that the service life of car pulleys is about eight years, and if you have not replaced the car pulleys for more than eight years, it will make a "cough" sound in the cold winter. If you want to change the pulley, it is recommended that you go to a regular car 4S shop to replace it, and do not do it yourself, otherwise improper operation will cause damage to the car.

1. The existence of most common abnormal noises of the engine depends on the speed state of the engine. Abnormal noise only exists when running at idle or low speed; The sound is disordered when it is maintained at a certain speed, and it makes a brief sound when it decelerates sharply; Abnormal noises occur when the engine accelerates sharply, and the sound persists when running at high speeds.

2. The abnormal noise failure of the engine is often obviously related to the working cycle of the engine, especially the abnormal noise of the crank connecting rod mechanism and the valve mechanism are related to the working cycle. Usually, the sound caused by clearances unrelated to the duty cycle is mostly due to faulty engine accessories; If there is a continuous metal friction sound emitted by a mechanical part that is not related to the duty cycle, it can be considered that some rotating part is faulty.

3. The problem of the filter collector, the rubber ring is not well sealed, so that the oil pump cannot suck up the oil normally and suck a lot of air when it is working, and the engine system is not lubricated enough, especially the hydraulic tappet part of the valve, which makes a metal knocking sound; The filter collector is clogged and does not properly draw oil into the engine lubrication system, resulting in poor lubrication.

It is generally due to the lack of rigidity of the body, after a long period of intense driving, or when walking to some bumpy roads. Some welded parts are slightly deformed, and after rubbing against each other, a sound is made, and the abnormal sound of the body generally does not have any serious dangerous consequences. However, it is more troublesome to solve, and the most common way is to add sponge or pad glue to those parts where friction occurs to try to alleviate this abnormal noise.

Abnormal noise is actually a fault warning, so it is very important to find the root cause of the noise and eliminate the noise. Language: Old drivers know that when the car has been driven for a long time, sometimes it is inevitable that there will be some noises, like an "alarm" for car failure.

If there is a sudden abnormal noise while driving, as a driver, you should be aware that there is something wrong with the car. It may be that some body parts are not fixed properly, tighten the screws and attach the tape, which can solve the problem of abnormal noise caused by the movement of the body parts. Tires have abnormal noises Most of the tires are tires.

Sometimes the problem of the vehicle is not easy to find according to the text, it is best to find a nearby professional and reliable maintenance shop to call the master to check it is more convenient, otherwise the after-sales service is OK, only the specific inspection can be effectively solved.

Hello: It is troublesome for the vehicle to have abnormal noise, and it is necessary to check the abnormal noise and eliminate it. In particular, chassis and engine squeaks must be taken into account.

If you can't check it yourself, send it to the auto repair shop for inspection!

Hello! Glad for your question.

Loose chassis generally occurs in older cars, when the car is driving in bad road conditions, the steering wheel will feel unstable, the bottom of the car will also come out of the abnormal sound, usually the old driver can feel the overall a little loose, when encountering such a situation, it means that the chassis may be loose, and the reasons for this situation are divided into several, only by understanding the reasons, can we better prevent this problem from happening.

The first reason is the aging of rubber parts, we all know that the elasticity of rubber is particularly good, which can buffer the friction between parts and reduce noise at the same time. However, this kind of thing has a lifespan, and it will age after a long time, and the elasticity is not as good as before, so the buffering capacity will decrease, resulting in abnormal noise in each part, so it is necessary to check these rubber parts regularly and replace them in time.

The second possibility is the reason for the shock absorber, the main role of this part is to inhibit **, when the car is driving in the dustpan section, it will have an impact with the road surface, and the shock absorber can well ensure the smoothness of the car, if the shock absorber is damaged, there will be a scoop phenomenon, so that the chassis is loose, so usually check the shock absorber, if there is a leakage to repair in time.

The third is the clearance of the parts, that is to say, the ball head may be loose, this part is like the joint of the human body, if the ball head is loose, there will be a large gap between the lever and other connected parts, if the gap is too large, when crossing some dustpan roads, the screws between the subframe and the suspension will be loose, then the chassis will become loose, so usually check these two parts. Thank you.

The common causes of abnormal noise of automobile engine are as follows: 1. Engine knocking. The phenomenon is the abnormal sound of the engine making a "bell".

The engine knocks on the cylinder, mainly because of the sound caused by the piston skirt hitting the cylinder wall when the engine is running. It is usually due to poor lubrication conditions. The solution is generally to replace the four sets of the engine.

2. Abnormal sound of intake and exhaust system. For example, an air intake manifold leaks a noise that occurs when idling and intensifies as the engine speed increases. 3. The engine has a "hissing" noise, which is likely to be caused by a problem with the cooling system, resulting in overheating of the engine.

4. The engine has a "squeak" abnormal sound, especially when the air conditioner is turned on. In this case, it is likely that the belt of the engine is slipping. 5. The engine has an abnormal sound of "clicking", which is likely to be carbon accumulation in the engine.

It is recommended to use high-grade gasoline. In reality, there are many types of abnormal engine noises in automobiles. For example, the abnormal noise of the engine during rapid acceleration, the abnormal noise of the engine during cold start, the abnormal noise of the engine in the idle state, etc., should be analyzed differently in each case.

It is recommended to go to a 4S shop or a professional auto repair shop in time to let the maintenance personnel check, and only by determining where the problem is, can the symptoms be repaired.

If there is a vibration sound of the window glass during driving, it can be repaired, and the window can be repaired by going to the repair shop in time.

The abnormal vibration of the window glass is generally caused by the hardening and aging caused by the drying of the new car sealing strip or the long-term maintenance of the sealing strip. The aging of the rubber strip is the biggest possible cause of the abnormal noise of the car window glass, if it is a new car abnormal noise, naturally there is no need to replace the rubber strip randomly. Simply buy a lube online, apply it evenly to the strip, and try lifting the glass several times to see if the squeak has subsided.

If the aging of the strip is more serious, it is best to replace it directly.

Extended information: The introduction of abnormal noise in automobile windows is as follows:

The gap of the sealing strip of the car card slot is easy to bring dust and particles into the process of glass lifting, which is easy to cause abnormal vibration of the window glass, and if the dust and particles accumulate more and more, causing damage to the lifting motor, it will cause abnormal noise, and even affect the lifting function. Our solution is to use a tool to clean the debris in the rails.

When the car was driving on a bumpy road, the multinational automobile group adjusted its strategy towards China and improved the Chinese market. Automobile windows will be caused by loose fastening screws or buckles with abnormal noise, including glass fixing screws, lifting rail fixing screws, door trim buckles, other screws in the door trim panel, etc. To solve this small fault, you only need to go to the 4S store and ask the clerk to tighten it.

Inside or outside the car, there is no big problem in the car, it belongs to the pedal friction noise, and the outside of the car is the sound of the gearbox clutch system, which needs to be checked and judged by the master on site!

If you hear the abnormal sound of "Zizi" in the process of driving, and this is the abnormal sound caused by the problem of the engine belt, because the abnormal sound of "Zizi" is mostly the aging of each belt group of the engine, or the belt is too loose caused by the problem of the tensioner, the friction abnormal sound, belt slippage, etc., if there is a similar "Zizi" abnormal sound, then look for the major belt groups and tensioners inside the engine, such as engine timing belt, generator belt, circulating water pump belt, air conditioning belt, power pump belt, etc. The problem that causes this abnormal noise is the abnormal sound of the engine belt, which is caused by the smooth grinding surface of the joint surface of the belt and the pulley. It usually occurs when the engine speed changes rapidly, and sometimes the belt rings when the load of the attachment driven by the belt increases.

How to solve the problem of abnormal noise of engine belt.

1. Check whether the accessories driven by the belt are damaged, stuck, loose or the power of the accessories has increased.

2. Replace the belt, or use 100 gauze to polish the joint surface of the pulley and the belt (light grinding is fine).

3. The temporary solution can be to drop 1 2 drops of oil on the joint surface of the belt and the pulley (it will not affect the belt slippage).

If it is the generator belt that rings and the headlights are more obvious, you have to take off the generator belt, turn the motor pulley to see if the generator rotates smoothly, if the generator is normal, you can check whether the battery is not stored power, because the battery storage is not good will increase the load of the generator.
