How to prevent car damage in cold weather

In the cold winter, people need to keep warm and cars need to be protected. How to carry out winter car maintenance and what skills are most concerned by car lovers. The following summarizes some common sense and methods of car maintenance in winter, hoping to help everyone.

antifreezing fluid

The weather is getting colder and colder, and the core care for the car must of course start from the heart of the car-the engine. The choice of antifreeze is the most important thing for the health of the "heart" of the car, so what problems should consumers pay attention to when choosing antifreeze?

The lower the freezing point, the better. The basic indexes of antifreeze are freezing point and boiling point. Use low freezing point antifreeze in autumn and winter. The lower the freezing point, the stronger the antifreeze performance. In general, the freezing point of the selected antifreeze should be lower than the local minimum temperature 10℃ to prevent sudden weather changes.

Attention should be paid to anti-corrosion function. There are many kinds of antifreeze in the market, and the quality is inevitably mixed. The antifreeze produced by general manufacturers is put on the market only after the freezing point of antifreeze is determined. These products without formal inspection are often very corrosive, causing damage to the cooling system of automobiles. Some antifreeze will also corrode the perforated water tank and flow into the engine, causing major accidents. Therefore, users are advised to choose regular brand antifreeze.

Pay attention to the use of antifreeze.

Note 1: Try to use the same brand of antifreeze. Different brands of antifreeze will have different production formulas. If mixed, various additives are likely to have a chemical reaction, leading to the failure of additives.

Note 2: the validity period of antifreeze is mostly two years (individual products will be longer), so make sure that the products are within the validity period when adding.

Note 3: It must be replaced regularly, usually every two years or every 40,000 kilometers. Taxis should be changed more frequently. When replacing, drain the old liquid, clean the cooling system, and then replace the new liquid.

Note 4: Avoid mixing with water.

storage battery

In the initial stage of starting the automobile engine, the generator will drive the engine to supply power to the automobile electrical system, and when the engine speed reaches a certain level, it will automatically enter the charging state. Therefore, except when the generator provides all the power supply for the whole vehicle at startup, it is battery-powered at other times. Especially for engine starting and lighting, batteries are needed to provide powerful power. When the car is driving in a cold area, it is necessary to avoid the complete discharge of the battery to avoid the freezing of the electrolyte.

Don't replace the car with a battery with a larger capacity than the original battery. Because the power output of the automobile generator is fixed. If a large-capacity battery is replaced, the new battery will be under-charged, the car will not start smoothly, and the long-term battery wear will shorten its life. When the car is started, the starting time should not exceed 3 to 5 seconds each time, and the interval between restarting should not be less than 15 seconds. Because there is weak current consumption in the vehicle circuit system when parking, standing the vehicle for a long time will lead to battery exhaustion. Therefore, for vehicles that have not been used for a long time, everyone should unplug the negative battery to avoid excessive battery consumption.
