The importance of car maintenance

Spring is a romantic season and a rainy season. During the period of Spring Festival travel rush in Guangzhou, the convergence of cold and warm air, returning to the southern sky and rain occurred from time to time, which also added extra troubles to the riders. Because rain is acidic, paint, chassis and other parts are easily corroded. At the same time, coupled with the humid weather, every dead corner in the car is easy to breed bacteria, and the air conditioner will also have an odor. It is worth noting that wet weather will also bring additional safety hazards to driving. Therefore, it is very important to maintain and use cars correctly.

1, the key parts should be checked in time.

The first step of car maintenance is to check the key parts in time. As early as the Spring Festival holiday, many people will drive to the countryside to visit relatives, and there will be dust or sand in the engine compartment. If it is not cleaned, it will seriously affect the heat dissipation of the engine. Therefore, it is necessary to check the engine compartment frequently and clean it regularly during the use of the car.

In addition, as the weather gets warmer, rubber parts such as wipers and tires are prone to cracking and aging. Considering the abundant rain in spring, if the wiper and tires can't work normally, it will directly affect the safety of people in the car. The way we check the wiper is also relatively simple. If the wiper can't clean the rain when working, or the wiper blade cracks and hardens, it needs to be replaced.

Brake oil is also worth checking. The replacement cycle of brake oil is relatively long, usually 40,000 kilometers or once every two years. However, due to the high humidity in spring, once the brake oil is mixed with water, the braking force of the vehicle will be reduced or even completely lost. However, it is far from satisfying the actual demand to judge whether the brake oil will continue to be used only according to the color, taste and feeling. Only qualitative or quantitative analysis of the brake oil is accurate. Generally speaking, when the moisture absorbed by brake oil reaches 2.5%, it is necessary to replace it with new brake oil.

2. Hygienic problems caused by moisture

The rising temperature and humidity provide a hotbed for the rapid propagation of bacteria. I believe that many riders will have a smell when using car air conditioners, which often appears, especially in older vehicles. Generally speaking, the main source of automobile air conditioning odor is bacteria growing on the leaves of evaporation box.

There are many products on the market to remove the odor inside the car, such as activated carbon bag and car air purifier. But the most effective way is to remove the evaporation box and clean it. However, the evaporation box is usually installed inside the dashboard, which is a huge project and inefficient for the owner.

If you want to solve this problem simply, try the method suggested by Brother Wheel: Turn off the air conditioner and refrigeration three minutes before the vehicle arrives at the destination, and switch to the natural wind mode, so that the evaporation box can rise to the same temperature as the outside of the vehicle, and the water on the surface of the evaporation box can evaporate as soon as possible. Or, when the vehicle is parked, adjust the air conditioning temperature to the highest, and let the hot air dry the moisture in the evaporation box and air conditioning pipeline.

Of course, in addition, the vehicle should be clearly defined inside and outside. The first is car paint, which contains acidic substances. When there is a lot of rain in spring, the car paint can be carefully cleaned and waxed, and the car clothes can be attached if funds permit. Lu Ge suggested that friends who like to wash cars should use high-pressure water guns and some acidic or alkaline cleaners with caution. After all, in daily automobile use, there are not many acids, alkalis or sticky substances attached to automobile paint.

Secondly, in the car, when cleaning the car, we can clean the exposed positions such as car seat cushion, foot pad, steering wheel cover and air outlet of air conditioner, and if possible, we can do a negative ion ozone disinfection. This way can disinfect every corner of the car and make the air inside the car fresh enough. Especially for used cars or newly used cars, negative ion ozone disinfection is very necessary.

Don't forget to change the liquid.

For riders living in the north, use lower grade engine oil in winter, which can improve the grade in spring. Every oil has a label, such as 0W40, 5W30, etc. The greater the number before W, the better the fluidity of lubricating oil at high temperature, which is suitable for use in spring and summer. The number after W indicates the viscosity of engine oil at 100℃, and the higher the number, the higher the viscosity.

But if you usually use multi-viscosity oil, you don't need to change it. Because this kind of engine oil contains many special additives, it is easy to flow in low temperature environment, but it can maintain proper viscosity in high temperature environment and always has good lubrication performance.

In addition, pay attention to adding antifreeze. If your car environment is mainly in the urban area, there is no impurity in the antifreeze and it has not reached the replacement cycle, it is usually not necessary to replace it. However, like engine oil, it needs to be kept in sufficient quantity to ensure the normal operation of the engine. If the oil content of the kettle is as low as the minimum line, it needs to be added. However, it should be noted that the added stock solution is best consistent with the coolant used in the original car, because the components of different coolants are different, so as to avoid chemical reaction between the two coolants and block the engine waterway.

Step 4 write it at the end

There are still many skills in car maintenance and car use in spring. This paper focuses on some important or easily overlooked methods. I believe that if you can check the above points in time, you will be able to keep the vehicle in better working condition and the interior environment will be healthier, which is of course related to your own mentality and driving habits. Need to be reminded, whether in spring or other seasons, car maintenance is a thing that can not be ignored.
