1、更换合适的机油
1. Change the appropriate oil
进入冬季，天气变冷，机油会随着温度的下降变得粘稠，沉积在发动机底部的油底壳中。
In winter, when the weather becomes cold, the oil will become viscous with the decrease of temperature and deposit in the oil pan at the bottom of the engine.
如果机油选用不当，轻则造成发动机起动过程中抖动、异响，重则造成无法起动。
If the engine oil is not selected properly, it may cause shaking and abnormal noise during engine starting, or it may cause failure to start.
所以，你应该根据当地的气候条件，更换适合气温的机油，建议尽量选用在较低和较高的温度下，粘度都能保持恒定的机油。
Therefore, you should change the engine oil suitable for the temperature according to the local climate conditions. It is recommended to try to choose the engine oil with constant viscosity at lower and higher temperatures.
北方大部分地区冬天可以使用5W-40、5W-30等型号机油，而像东北零下几十度的地区的话，0W-40或0W-30型号的机油会更合适。
In most areas of the north, 5W-40, 5W-30 and other engine oils can be used in winter, while 0w-40 or 0W-30 engine oils will be more suitable in areas with tens of degrees below zero in the northeast.
2、更换防冻液
2. Replace antifreeze
防冻液和冷却液，说的都是一回事儿，就是在发动机冷却系统中循环的带有防冻等功能的冷却介质，通俗的讲就是给发动机降温的。
Antifreeze and coolant are the same thing, that is, the cooling medium with antifreeze and other functions circulating in the engine cooling system. Generally speaking, it is to cool the engine.
主要作用为保护发动机正常良好运行，在发动机水箱内循环，起到防冻、防沸、防锈、防腐蚀等效果。
The main function is to protect the normal and good operation of the engine, circulate in the engine water tank, and play the effects of anti freezing, anti boiling, anti rust and anti-corrosion.
因此，你应该根据当地的气候条件，更换相应的冷却液，保证在你所在地温度下不冻结，一般冷却液的冰点有-45℃、-30℃和-25℃等 3 种。
Therefore, you should change the corresponding coolant according to the local climate conditions to ensure that it will not freeze at the lowest temperature in your place. Generally, the freezing point of coolant is - 45 ℃, - 30 ℃ and - 25 ℃.
3、更换防冻玻璃水
3. Replace antifreeze glass water
入冬前要将常温型玻璃水用完，以免冻裂水壶，并根据你当地的气温更换冬季防冻型玻璃水。
Before winter, use up the normal temperature glass water to avoid cracking the kettle, and replace the antifreeze glass water in winter according to your local temperature.
如果你不太在乎，那我建议你直接选用-30℃的更好。
If you don't care much about the price, I suggest you choose - 30 ℃ directly.
4、检查汽车电瓶
4. Check the car battery
进入冬季，由于气温降低，电瓶的储电量受温度影响也会相对下降。
In winter, due to the decrease of temperature, the storage capacity of battery will also decrease relatively under the influence of temperature.
所以你平时就要多注意检查电瓶是否亏电，是否缺少电解液，电解液比重是否正常等。
Therefore, you should pay more attention to check whether the battery loses power, lacks electrolyte, and whether the specific gravity of electrolyte is normal.
5、检查或更换轮胎
5. Check or replace the tire
经常检查轮胎花纹是否在线内，是无论冬季、夏季都必须要做的日常检查。
Regularly check whether the tire pattern is within the safety line, which is a daily inspection that must be done in winter and summer.
如果轮胎磨损超过线、轮胎表面橡胶老化严重、胎侧有裂纹或鼓包，那你就得及时更换了。
If the tire is worn beyond the safety line, the rubber on the tire surface is seriously aged, and there are cracks or bulges on the sidewall, you have to replace it in time.
任何的轮胎都会在胎面沟槽底部设置一个磨损标记。一般轿车轮胎的磨损标记高度为 1.6 毫米（这个高度也是法定的轮胎更小沟槽深度）。
Any brand of tire will set a wear mark at the bottom of the tread groove. Generally, the wear mark height of car tires is 1.6mm (this height is also the legal minimum groove depth of tires).
轮胎的花纹和沟槽的主要作用是增大磨擦、排水等，如果你所在地区，冬季经常会出现路面有积雪，应该备一套雪地胎，同时还要养成经常清理胎花内异物的好习惯。
The main function of tire patterns and grooves is to increase friction and drainage. If there is often snow on the road in your area in winter, you should prepare a set of snow tires, and develop the good habit of often cleaning foreign matters in the tire flowers.
