Picking used cars with ears
When buying a used car , you must not only look at your eyes, you must also learn to listen with your ears. Used cars tend to experience some noise, noise is normal, there may be a hidden glitch, reminding consumers to choose a used vehicle launch vehicle or test the noise. Objectively speaking, a car must be larger than the chassis of the new car after several tens of thousands of kilometers of years, noise of the engine noise, but can be seen from the vehicles with some abnormal noise symptoms. Noise, exhaust pipe, is normal aging. More than one year used cars because of the body after the rain, snow and other regular contact can cause corrosion, leakage and other phenomena, the gas will be heard "in the process, suddenly" sound, change the exhaust noise can be eliminated after. Two, the cause of engine noise analysis, engine noise is more complex. Some are. Therefore, the used car network prompts you to have some due to human negligence, resulting in light leakage, such as an oil antifreeze or defined several times more than maintenance kilometers or maintenance. The solution is to replace the part. Third, the noise of the chassis system, chassis noise caused by a variety of reasons, but as long as it is not the cause of serious resistance is no problem. For example, bearing wear, loose ball, shock absorber failure and other reasons will produce abnormal noise, I suggest you go to the store to detect fault repair. The last is the body's noise, which is due to the whole year. Because the vehicle is moving, the road vibrations cause constant torque and the entire body bends, which will surely cause the loose parts to drive kilometers.
