在寒冷的天气下，对车主和爱车而言都是一场严峻的考验。不少车主开始担心冬天水箱会结冰。那么济南哪里修奥迪比较专业厂家今天就和大家聊一聊为什么水箱会结冰，以及该如何去解决。

In cold weather, it is a severe test for owners and their cars. Many car owners are worried that the water tank will freeze in winter. So where is the most professional manufacturer of Audi in Jinan? Let's talk about why the water tank freezes and how to solve it.

为什么水箱会结冰?

Why does the water tank freeze?

其实车主们的担忧不无道理，这是因为不少车主为了省钱，仅仅使用自来水作为车辆冷却系统的传热介质，这在以前是很常见的事情。由于水的冰点为0°C，当温度处于零下时，水箱以及冷却系统的其它部分就会容易结冰。

In fact, the concern of car owners is not unreasonable. This is because many car owners only use tap water as the heat transfer medium of the vehicle cooling system in order to save money. This is a very common thing in the past. Since the freezing point of water is 0 ° C, when the temperature is below zero, the water tank and other parts of the cooling system will easily freeze.

为了使车辆在冬季能正常出勤，现在加的都是防冻冷却液，就是具有防冻功能的冷却液，一般由水、防冻剂和添加剂组成。其中占比大的还是水，因为水的比热容较大并且热传导快，在吸收热量后容易散发。不过加入一定量的防冻剂后，可以降低冷却液的冰点。

In order to ensure the normal attendance of the vehicle in winter, the antifreeze coolant is added now, which is the coolant with antifreeze function, and is generally composed of water, antifreeze and additives. It is water that accounts for a large proportion, because water has a large specific heat capacity and fast heat transfer, which is easy to dissipate after absorbing heat. However, adding a certain amount of antifreeze can reduce the freezing point of the coolant.

但有时明明加的是冰点足够低的防冻冷却液，为什么水箱也会结冰呢?这个问题其实也很好解释。冷却液在日常的使用过程中难免会出现挥发，在酷热的夏季会更加明显。部分卡友在看到冷却液液面高度不足时，就会加点自来水应急。但是冷却液加了水后浓度会变稀，久而久之防冻性能就会有一定的损失，从而导致冷却液的冰点上升，无法抗住严寒天气，除非一直不熄车。

But sometimes the antifreeze coolant with low freezing point is clearly added. Why does the water tank freeze? This question is actually easy to explain. The coolant will inevitably volatilize during daily use, especially in the hot summer. Some users will add tap water for emergency when they see that the coolant level is insufficient. However, the concentration of the coolant will become thinner after adding water, and the antifreezing performance will be lost over time, which will lead to the rise of the freezing point of the coolant, which cannot withstand the severe cold weather, unless the vehicle is not stopped all the time.

冷却液结冰后该怎么办?

What should I do after the coolant freezes?

如果遇到这种情况，首先我们不能启动发动机，因为水箱结冰意味着整个冷却系统管路内的冷却液都凝固了。贸然打着车辆会使水泵以及皮带损坏，导致冷却系统无法正常工作。冷却系统损坏故障继而会令发动机过热，出现粘缸的状况。

In this case, we cannot start the engine at first, because the freezing of the water tank means that the coolant in the entire cooling system pipeline has solidified. The water pump and belt will be damaged if you hit the vehicle carelessly, resulting in the cooling system not working properly. If the cooling system is damaged, the engine will overheat and the cylinder will stick.

此时，我们需要仔细检查水箱和管路的状态。如果结冰程度严重，将水箱和管路胀裂，那就需要呼叫维修人员进行零件更换。如果检查后发现各部件完好，可以自行对冷却液实施解冻。

At this time, we need to carefully check the status of the water tank and pipeline. If the water tank and pipeline are cracked due to severe icing, it is necessary to call the maintenance personnel to replace the parts. If the components are found to be in good condition after inspection, you can defrost the coolant by yourself.

为了避免冷却液结冰的现象再次发生，我们应该在冬季来临前及时更换适宜当地环境温度的冷却液，万一等到冷却液结冰了再更换，机件冻坏后的维修费用很可能会更高。一般情况下，都是根据所处地区的气温来选择冷却液型号，建议选择冰点比该地区低气温低5°C~10°C为宜。

In order to prevent the phenomenon of coolant icing from happening again, we should replace the coolant that is suitable for the local ambient temperature in time before the winter comes. In case of replacing the coolant when it freezes, the maintenance cost of the parts after freezing is likely to be higher. Generally, the coolant model is selected according to the temperature of the region where it is located. It is recommended that the freezing point be 5 ° C~10 ° C lower than the low temperature of the region.

除了选择合适型号的冷却液之外，在补充冷却液时也要注意，不要混加其他型号的冷却液。因为不同的冷却液中所含的的防冻剂、添加剂是不一样的，混合使用的话可能会产生未知的化学反应，严重的话甚至造成冷却液变质和失效。不仅无法提供散热能力，损伤发动机，还会浪费冷却液。有关汽车维修或者维护的事项就来我们网站http://www.lutongqixiu.com咨询吧！

In addition to selecting the appropriate type of coolant, pay attention not to mix other types of coolant when replenishing the coolant. Because the antifreeze and additives contained in different coolants are different, mixed use may produce unknown chemical reactions, or even cause deterioration and failure of the coolant. It can not only provide heat dissipation, damage the engine, but also waste coolant. Come to our website for matters related to car repair or maintenance http://www.lutongqixiu.com Ask!
