When you see the drainage, you start to drain. At this time, check the temperature of the drain. The engine should be idling in the car. Other places may freeze to thaw.
Observe whether there is frost crack and water seepage in the water tank and body, and go to a professional place to check the condition of the car. You should know that you can't light a fire after the water tank freezes. Only after thawing in the above way can other operations be carried out. Expansion during freezing may cause the pipeline in the water tank to break.
Boiling the water tank is harmful to the engine, and the water thermometer usually points to 100℃. The thermometer freezes before the water tank cools, so the temperature will not change. It can be judged that the car's water tank is frozen. Moreover, we must learn to observe when the car engine is turning to prevent water from infiltrating into the cylinder. In severe cases, the engine will be scrapped.

Winter car maintenance:
Changing winter oil requires high lubrication in winter. If the temperature in your place is low in winter, you need to change the winter oil. Oil is numbered, such as 0w40 and 5w30. The smaller the number before W, the better the low-temperature fluidity of lubricating oil, the lower the viscosity of engine oil and the higher the starting speed of engine. At the same time, the lower the pour point of engine oil, the faster it can reach the lubrication part and reduce hard friction. Generally, 5w is more suitable if it is not too cold.
Preventing antifreeze from freezing The function of antifreeze is to cool down and prevent freezing. In the north where the temperature is low, antifreeze should be replaced with low-temperature resistant one, so as not to freeze the engine and even damage the engine and water tank. In addition, it should be noted that the service life of general antifreeze is 2-3 years, so it should be replaced in time.
Check and replace the right tire. Four-season tires are widely used in cars nowadays. If there is a snowy road, you need to change into winter snow tires, sometimes even more useful than four-season tires and four-wheel drive. In addition, tire rubber will harden in winter, so we should pay attention to tire aging. If it is broken or seriously aging, it needs to be replaced in time. As for the tire pressure, some people say that it can be raised a little, but it can be guaranteed to be within the normal range of the manual. If conditions permit, you can also do four-wheel positioning.
