Cars, like people, have a life cycle between life span and car condition. In different periods of use, the condition of vehicles varies greatly. Just like young people go to the gym, middle-aged people go to the massage room and old people go to the chess room, if you want to keep your car in good condition, you need to know the precautions in different periods of maintenance.

1. Running-in period: vehicle age 1 year.

At this time, the car is in the best condition, which is equivalent to youth. If the vehicle has any quality problems, it can be found within one year.

As long as you do regular maintenance, troubleshoot in time and pay attention to safe driving.

By the way, many friends just bought cars, and I don't know when I can buy the first insurance and the second insurance. If you know what I mean, please read the manual. How to write the instructions? You can come here, because some cars are guaranteed for the first time after 2500 kilometers, only checking and not changing parts. After that, every six months or 5000 kilometers, some cars are guaranteed 5000 kilometers, and so on. The number of kilometers and hours can fluctuate slightly, but not too much. As for why, we'll talk about it later.

2. Golden period: car age 1~3 years.

Three years is the warranty period, and the maintenance cost will increase after three years, so within three years, it is also called the golden period of vehicles. During this period, although the vehicle is worn, it still has good performance and running state. For the maintenance of this period of time, it is the following aspects:

1) General dimension maintenance

2) Vehicle inspection, including but not limited to:

① Working conditions of wiper, lighting and reversing radar.

② Engine compartment

③ Chassis condition

④ Tire (including spare tire)

⑤ Brake system components

These are fragile and consumable parts, which are related to driving safety. If we want to cross the three-year warranty smoothly, we must pay attention to them.

3. Maturity: 3~5 years old.

Just like people over 30 years old, they slowly start to decline, and so do cars. In the last three to five years, the quality weakness of automobiles will begin to appear: aging parts, oil leakage, water leakage and other problems, of course, good quality is still very eye-catching.

Generally speaking, there are more used cars that are more than five years old, because at this time, the vehicles are in good appearance and can be sold at a good price. Therefore, the following aspects of the vehicle should be inspected and maintained:

① The quality of brake pads is directly related to the braking effect. The lower the cost, the faster the wear. It is suggested to replace the friction material in time according to the use situation.

② Fuel pumps that have been running for more than three years should be basically cleaned or replaced.

③ Shock absorber, a part of suspension. If you feel that driving is not as smooth as a new car, you should check the shock absorber.

When should these things be changed? Most of them are not written in the vehicle manual, so the basic idea is: pay more attention to inspection than maintenance, and solve problems in time when found.

4. Decline period: vehicle age is 6~ 10 year.

This period of time can be compared to the old age of human beings. If the vehicle has been running for six to ten years, the performance can be said to be declining year by year, and the maintenance cost will also increase year by year.

Just as human beings will inevitably get old, so will the aging of cars. Problems such as rubber parts, air conditioning, car paint and power system will become more prominent. Considering the car experience involved, it is recommended to repair or replace it if possible. Cleaning the engine and changing the oil can alleviate the decline of vehicle dynamic performance.

At the same time, it is necessary to strengthen the maintenance of automobiles, and the frequency of checking the condition of automobiles in specialty store can be appropriately increased.

5. Elimination period: 10~ 15 years old.

Although the mandatory retirement period of non-operating vehicles has been cancelled in China, the performance of each part of the vehicle has greatly deteriorated at this stage, and the owner is worried about breaking down on the road.

Last summer, a relative of Dong Ge's family took a 10-year-old car to travel, almost halfway. Do you think this is irritating? Cars in this period, let it stay in the garage to recuperate, or send it to the scrap yard to sell scrap iron. In principle, you can only drive in the urban area or within a short distance, so you should be fully prepared.

Practically speaking, it is recommended to change to a new car when using this period. If you want to use it, you must pay attention to these aspects:

① Power system maintenance

② Thoroughly clean the water tank.

③ Whether the chassis is seriously damaged or rusted.

④ Whether the suspension shock absorber leaks oil.

⑤ Pay attention to regularly check and replace tires and batteries.

In addition, in actual use, we should pay attention to try not to pull the engine speed too high to avoid fierce driving.
