What should I do if the car makes an abnormal noise?Teach you how to identify car noise

【The owner's family car knowledge】Abnormal noise is not a disease, it sounds terrible! When it comes to the abnormal noise of a car, I believe that everyone who drives a lot will feel the same. It has been troubled for a long time, but they can’t find out the cause of the abnormal noise, or choose to accept it, or continue to investigate. The unsuccessful are not among the few people. When driving on the road every day, even the small noise is enough to make people irritable and worried. Is there really a hidden danger of major problems in the vehicle? The vehicle will make a certain noise in the normal driving process. , But if this kind of noise exceeds a certain range, it can be regarded as abnormal body noise.

1. Learn to distinguish abnormal sounds that are reasonable sounds

With regard to the problem of abnormal car noise, it is difficult for ordinary car owners to distinguish which are fault abnormal noises and which are reasonable abnormal noises. Go to the repair shop to detect abnormal noise vehicles, only nearly 20% of the vehicles really have problems. For models equipped with a turbocharged engine, there must be a difference between the noise and the sound of a naturally aspirated engine; models with an engine guard plate may also produce noise due to friction; some car owners may be caused by themselves after contacting different cars. Lack of understanding of mechanical knowledge, mistaken reasonable abnormal noise for vehicle failure. Therefore, learn to distinguish abnormal car noises and avoid wasting time and energy.

Here are some abnormal noises that are not malfunctions:

Owner:When my car is driving on a highway, the engine will make a loud noise. Why do I want to check it through the "free test"?

expert:It is normal for a car to make loud noises when driving on a highway, because when the vehicle is driving at a high speed, the engine rotates at a high speed, and the sound is naturally louder than when driving at a slow speed. If the sound of the engine is uniform, it is normal. If the sound is uneven, you need to enter the station to determine the problem.

Owner:When my car is cold and rainy, the brakes will make abnormal noises. I want to know how to deal with it?

expert:Under normal circumstances, friction will occur as long as the brake is used, and there will be noise. If the noise is irregular when using the brake, check whether the running-in surface of the brake is normal. If it is raining, the brakes will make abnormal noises. If they do not, the brakes should be no problem. Because driving in rainy weather, the brakes will easily adhere to the mud and sand splashed by rain, which will cause abnormal brakes.
