1、更換合適的機油
1. Change the appropriate oil
進入冬季，天氣變冷，機油會隨著溫度的下降變得粘稠，沉積在發動機底部的油底殼中。
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.
如果機油選用不當，輕則造成發動機起動過程中抖動、異響，重則造成無法起動。
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，你應該根據當地的氣候條件，更換適合氣溫的機油，建議盡量選用在較低和較高的溫度下，粘度都能保持恒定的機油。
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.
北方大部分地區冬天可以使用5W-40、5W-30等型號機油，而像東北零下幾十度的地區的話，0W-40或0W-30型號的機油會更合適。
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、更換防凍液
2. Replace antifreeze
防凍液和冷卻液，說的都是一回事兒，就是在發動機冷卻系統中循環的帶有防凍等功能的冷卻介質，通俗的講就是給發動機降溫的。
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.
主要作用為保護發動機正常良好運行，在發動機水箱內循環，起到防凍、防沸、防銹、防腐蝕等效果。
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，你應該根據當地的氣候條件，更換相應的冷卻液，保證在你所在地溫度下不凍結，一般冷卻液的冰點有-45℃、-30℃和-25℃等 3 種。
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、更換防凍玻璃水
3. Replace antifreeze glass water
入冬前要將常溫型玻璃水用完，以免凍裂水壺，并根據你當地的氣溫更換冬季防凍型玻璃水。
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.
如果你不太在乎價格，那我建議你直接選用-30℃的更好。
If you don't care much about the price, I suggest you choose - 30 ℃ directly.
4、檢查汽車電瓶
4. Check the car battery
進入冬季，由于氣溫降低，電瓶的儲電量受溫度影響也會相對下降。
In winter, due to the decrease of temperature, the storage capacity of battery will also decrease relatively under the influence of temperature.
所以你平時就要多注意檢查電瓶是否虧電，是否缺少電解液，電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、檢查或更換輪胎
5. Check or replace the tire
經常檢查輪胎花紋是否在安全線內，是無論冬季、夏季都必須要做的日常檢查。
Regularly check whether the tire pattern is within the safety line, which is a daily inspection that must be done in winter and summer.
如果輪胎磨損超過安全線、輪胎表面橡膠老化嚴重、胎側有裂紋或鼓包，那你就得及時更換了。
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.
任何品牌的輪胎都會在胎面溝槽底部設置一個磨損標記。一般轎車輪胎的磨損標記高度為 1.6 毫米（這個高度也是法定的輪胎更小溝槽深度）。
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).
輪胎的花紋和溝槽的主要作用是增大磨擦、排水等，如果你所在地區，冬季經常會出現路面有積雪，應該備一套雪地胎，同時還要養成經常清理胎花內異物的好習慣。
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.
