With the development of the times, more and more people have experienced the convenience that cars bring to people's lives. For Xiao Bai, who just bought a new car, the joy of buying a new car is not over yet, and he will face the big problem of difficult car maintenance.

2. Can the liquid in the water tank become water?

Everyone has boiled water at home. You should know that the boiling point of water is about 100 degrees, and the boiling point is low. When the temperature is below 0 degrees, water will freeze again. Therefore, this liquid has no stability, which will seriously damage the water tank, auxiliary water tank, water pipe, engine and so on. In places with poor water quality, such as hard water (with more minerals), scale will also be produced on the cooling system, thus affecting the cooling effect. Coolant Coolant has the characteristics of rust prevention, high boiling point and low freezing point, and its stability and safety are relatively high.

The most important thing in driving is safety.

The most important thing in driving is safety. The parts most closely related to safety are tires and brake pads. Automobile tires must be regularly inspected and maintained by professional testing institutions to ensure the smooth operation of tires and improve driving safety. As the most important performance of the car, the braking performance of the car is naturally consumed due to long-term use, so it is necessary for the owner to check the brake pads regularly and replace them in the repair shop if necessary.

4. Precautions for driving in summer

Driving in summer, due to the influence of high temperature, there are many hidden dangers when driving, especially for older cars, the wear and tear of internal parts of cars and the details of cars need our special attention. Don't drive too high tire pressure in summer. The surface temperature is high in summer. After long-distance driving, the tire itself is overheated, the air pressure in the tire becomes larger, the tire becomes soft, and it is easy to puncture.

After buying a car, I can't bear to drive.

Although some people have become car owners, they usually "don't want to drive" and only drive out to play on holidays. In fact, this way of using cars is very harmful to cars. The surfaces of transmission parts such as engine and gearbox will rust due to frequent direct contact with air, and the service life of batteries will also be affected by long-term natural discharge. The best way is to run for 30 to 40 minutes every few days. Besides, always using short-distance cars will also hurt cars. The car is moving at any time, but it is not far away, which is an important reason for car injuries. From the engine start-up to the stable stage, the parts on the car are most seriously worn, and it takes about 20 minutes to make up the power consumed by starting the car battery once. This habit of using a car can easily make the car break down early.

6. Reduce unnecessary burdens

If you put some heavy items in the car for a long time, it will increase the fuel consumption of the car in a subtle way, so items that are not used for a long time cannot be placed in the car.

7. Don't step on the brake for a long time without releasing it. This waiting time is already too long. The engine consumes enough oil to travel 65,438+0 kilometers when it is idling for 3 minutes. Therefore, once the waiting time is too long, it is best to turn off the engine, but if it stops for a short time, it is best to idle.
