&How to check common faults of second-hand cars
[Xinxiang second-hand cars]
Introduction: Cars all have common faults. Generally speaking, they occur many times and with high frequency, but they will not be fatal to the overall performance of the vehicle. Injurious glitches. Common faults include: engine failure to ignite, difficulty in starting, reduced engine power, large consumption of gasoline and oil, abnormal engine noise (such as valve knocking), incomplete clutch separation, noise from the chassis transmission system, and excessive acceleration time and distance. For a long time, the driving speed decreases, steering and brake failure occur, oil leakage, water leakage, air leakage occurs, electrical equipment, lighting lights, and other auxiliary electrical equipment fail, etc. These are common faults. Many of them can be eliminated by experienced drivers themselves.
Xinxiang Used Cars
It was established in 2010 and has been in business for more than 10 years now. It has its own place in the second-hand car industry, and it goes without saying much about its qualifications. The company's Gao Xiaozhong has been working in the second-hand car market for more than ten years. He has very rich experience in second-hand cars and has also accumulated his own personal connections.
Many vehicles will also have the above problems due to natural deterioration, improper operation by the original owner, etc. So what are the causes of these failures?
, natural deterioration.
During the long-term use of the vehicle, the various matching parts will wear each other, or be corroded by the medium, and the materials will be fatigued, aged, and deformed. These are the effects of natural deterioration, which will cause certain parts to fail and cause mutual interaction between parts, creating a vicious cycle. Natural deterioration accounts for the largest proportion of common vehicle failures around the year.
, Design and manufacturing are inherently deficient.
That is, the design and structure of the vehicle itself are unreasonable and imprecise, the material selection does not meet the requirements, and the strength is insufficient. The parts used have manufacturing defects, insufficient accuracy, etc. These are inherent deficiencies that will definitely cause hidden troubles for the vehicle on the road. Currently, manufacturers are implementing recalls for design defects. For example, one manufacturer recalled and replaced its rear shock-absorbing system.
, Improper maintenance.
For different brands and models, manufacturers will stipulate corresponding maintenance measures based on different structures and materials. Some car owners do not perform maintenance on their vehicles as required or on time, and do not perform according to the technical requirements of the specifications, resulting in poor technical condition of the vehicle and accelerating the occurrence of failures. For example, adding lubricating oil that does not meet the requirements will increase the wear of the matching parts, and even cause failures such as tile burning, shaft holding, and cylinder pulling.
, Improper operation.
The original car owner’s incorrect driving habits and incorrect operations may cause potential vehicle failures, such as not lifting the clutch pedal, rushing to refuel or brake, etc. Long-term overloading, speeding, and long-term driving in harsh road conditions and climatic conditions, such as bumpy roads, etc., will cause loosening and damage of mechanical parts, shortening the life of the vehicle.
