The importance of car maintenance

Spring is a romantic season and a rainy season. During the period of Spring Festival travel rush in Guangzhou, cold and warm air meet, return to the south, and rain happens from time to time, which also adds extra troubles to riders. Because rain is acidic, paint, chassis and other parts are easily corroded. At the same time, coupled with the humid weather, bacteria can easily breed in every dead corner of the car, and the air conditioner will 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, in the process of using the car, it is necessary to check the engine compartment frequently and clean it regularly.

In addition, with the warming of the weather, rubber parts such as wipers and tires are also 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 rain water is not cleaned when the wiper works, 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 feel. 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 an odor when using the car air conditioner, which often happens 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 often installed inside the dashboard, which is a huge project for the owner and is inefficient.

If you want to solve this kind of 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, switch to the natural wind mode, let the evaporation box rise to the same temperature as the outside of the vehicle, and let the water on the surface of the evaporation box 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 water 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 the funds permit. Brother Lu suggested that friends who like car washing should use high-pressure water guns and some acidic or alkaline cleaners with caution. After all, there are not many acids, alkalis and sticky substances attached to the car paint for daily use.

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

Don't forget to change the liquid.

For riders living in the northern region, using lower grade engine oil in winter can improve the grade in spring. Every kind of oil has a label, such as 0W40, 5W30, etc. The larger the number before W, the better the high-temperature fluidity of lubricating oil, which is suitable for spring and summer use. 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 engine 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, the antifreeze has no impurities and has not reached the replacement cycle, it usually does not need to be replaced. 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 Min 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 the 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 that car maintenance is a thing that can't be ignored, whether in spring or other seasons.
