It is understood that antifreeze must be used in winter. When the temperature is below zero degrees Celsius, if the cooling system of the engine is ordinary water, it is easy to freeze, which is not conducive to the start of the car and will almost cause serious damage to the engine.
According to statistics, cooling system failure is the primary cause of engine failure, accounting for about 60% of the total number of engine failures. So don't forget to check the antifreeze in winter. Manager Wang of an automobile shop in Yangzhou Road, jiaozhou city said that antifreeze is usually changed once every two years, but if ordinary water has been added to antifreeze, the replacement cycle of antifreeze should be earlier. Pay attention to the color of antifreeze when changing, and don't mix different colors.
As far as the choice of antifreeze is concerned, the lower the freezing point, the stronger the antifreeze. At present, the freezing point of antifreeze in the market has several specifications, such as-15℃, -25℃, -30℃, -40℃ and so on. , and the selected freezing point should be lower than the lowest temperature in this area 10℃ or above.
Even though the usage of wiper spray system will be significantly reduced in winter, it cannot be ignored, especially in the northern region. Like antifreeze, although it can be replaced by clean water and washing water in summer, these substitutes may freeze in winter, so don't use them in winter. In the environment below zero degrees Celsius in winter, the frost-resistant winter glass water should be replaced, or an appropriate proportion of alcohol should be added to the glass water to achieve the purpose of lowering the freezing point and freezing resistance.
It is recommended that all car lovers do a full-body "beauty" for their cars before winter. Waxing in early winter is a good way to maintain car paint, because the number of freezing and brushing cars will be reduced after winter. In addition, the waxed car body is not easy to get wet, and the car paint is not easy to condense into ice in winter.
