How to maintain the car in winter

The first is very hard tires. In winter, rubber will become hard and brittle, not only will the friction coefficient be reduced, but it is also easier to leak air and puncture tires than other seasons. In winter, you should often clean up the inclusions in the tire pattern to avoid using tires with large wear, and the four tires are the same brand, the same pattern, and the same specifications. In winter, the air pressure is low, and the tire must be full of gas to prevent puncture.

The validity period of the antifreeze is generally two years, and the expired antifreeze will cause corrosion of the cylinder body, and even serious damage to the engine. In addition, the freezing point of the antifreeze is generally around -25 ° C, and if you go to a colder place, you need to change the antifreeze with a lower freezing point. The specifications of the antifreeze should be selected, even in the coldest northeast region of China, your car can be alive and well.

Batteries are most afraid of low temperatures, and the battery capacity in low temperature environments is much lower than that at room temperature. Therefore, in winter, the electrolyte of the battery should be replenished in time, and the terminal post of the battery should be cleaned, and the special grease should be coated to protect it to ensure reliable starting and extend the life of the battery. If the vehicle is parked in the open for several weeks, the battery should be removed to prevent the battery from freezing and damaging.

In winter, you must not use tap water as glass cleaning liquid. Once the temperature is too low, pure water and tap water will freeze, and sometimes even break the container. Therefore, in winter, be sure to use a special glass cleaning liquid. When driving, the windows are generally closed, and the cold and warm air ducts are the only channels for air communication inside and outside the carriage. Cleaning the cold and warm air ducts is not only hygienic, but also reduces the volatile odor of interior materials.
