Health preservation, called "health preservation", "health preservation" and "health preservation" in ancient times, refers to the methods of strengthening physique, preventing diseases and prolonging life through various methods. People will try their best to prolong life. Similarly, car owners and friends also hope that their cars will not be "sick" and always serve themselves. Car maintenance experts say that after the average car has been used for more than seven years, problems will follow. Knowing some "ways of keeping in good health" of cars can make cars "prolong life". There is basically no problem for a car with a good foundation to be used for one year in the "newborn period", but it should be used with caution because the car is in the running-in period. The running-in period is generally around 5000 kilometers. During the running-in period, vehicles should not overspeed or overload, which can prolong the service life of vehicles and lay a good foundation for future use. Three years of "adolescence", more careful, no hidden dangers. When a child reaches puberty, his body will change, and at the same time, he will increase some "small temper", and so will cars. Three-year-old cars have the best performance, but some wearing parts may wear out and minor faults begin to increase. For example, brake pads and three filters (air filter, oil filter and machine filter) need to be inspected frequently. Many car owners think that their vehicles have been in operation for two years, and they are familiar with them and don't care so much about new cars. Speeding and overloading are commonplace, and some minor problems are not fixed. In fact, this is the easiest way to leave hidden dangers for future vehicle use. Please also take care of your car owners and friends, and don't lose too much because of small things. Five-year "middle-aged" physical examination on time reduces the use of faulty vehicles and enters the "middle-aged" period after about five years. At this time, the engine, transmission and other components may begin to have problems. At this time, the host's friends will be willing to pay, and the "disease" to be cured will be completely cured. Generally speaking, at this time, the family car traveled about 654.38+ 10,000 kilometers. Although the quality of cars is very reliable now, after all, time waits for no one, not to mention that the rubber parts and paint of cars have begun to age and the engine has begun to "get sick". At this time, it is necessary to send the car to a professional repair shop for a comprehensive "physical examination" to reduce the chance of failure. Experts remind car owners and friends that tires, circuits, timing belts, engine rubber parts, clutch plates, braking systems and steering systems all need special care, and the tires should not be used more than 654.38 million kilometers, even if the tires are not broken; At this time, the vehicle circuit system is most prone to failure, such as short circuit. It is suggested that car owners should not install high-power audio and other electrical equipment at will to prevent circuit overload from causing fire.
