近有车友抱怨：几天没开车早上开车时发现防冻液没了，那么消失的防冻液去哪儿了？下面
济南奔驰汽车维修厂家就为大家解开“防冻液消失之谜”！
Recently, some car enthusiasts complained that they had not driven for a few days and found that the antifreeze had run out when driving in the morning. So where did the lost antifreeze go? Below, the Jinan Mercedes Benz car repair manufacturer will unravel the mystery of the disappearance of antifreeze for everyone!

冷却系统渗漏
Cooling system leakage
冷却系统有很多部位可能发生渗漏，比如水管、水堵等。一般情况下，渗漏都是比较容易发现的。可是有些部位的渗漏，由于特别轻微，比较难发现，只要我们认真观察，一定能够找到渗漏的部位，然后我们对症下药，把相应的部位紧固或者重新安装就好了。
There are many parts of the cooling system that may leak, such as water pipes, water plugs, etc. In general, leakage is relatively easy to detect. However, some parts of the leakage are particularly mild and difficult to detect. As long as we carefully observe, we can definitely find the leakage area, and then we can apply the appropriate medicine to the case, tighten or reinstall the corresponding parts.

水箱盖损坏
Damaged water tank cover
冷却系统上的水箱盖并不是普通的盖子，而是在其内部带有空气阀和蒸汽阀的特制盖子。如果这个盖子出现了故障，特别是蒸汽阀开启压力过低或者处于常开位置，就会导致大量的水蒸气从这儿漏出，时间长了防冻液就会缺失，这是防冻液缺失的主要原因。
The water tank cover on the cooling system is not a regular cover, but a specially designed cover with air and steam valves inside. If this cover malfunctions, especially if the steam valve opening pressure is too low or in the normally open position, it will cause a large amount of water vapor to leak out from here, and over time, the antifreeze will be lost, which is the main reason for the loss of antifreeze.

防冻液不符合使用标准
The antifreeze does not meet the usage standards
现在汽车发动机工作温度都在90~105°C之间，为了避免防冻液沸腾，防冻液的沸点一般都在108°C以上，同时它的蒸发量也会受到严格的限制。如果防冻液不符合使用标准，会导致领取系统内部压力过大，将蒸汽阀顶开，水蒸气泄漏，久而久之就会造成防冻液缺失。
At present, the operating temperature of automobile engines is between 90 and 105 ° C. In order to avoid boiling of antifreeze, the boiling point of antifreeze is generally above 108 ° C. At the same time, its evaporation will also be strictly limited. If the antifreeze does not meet the usage standards, it will cause excessive internal pressure in the receiving system, open the steam valve, and cause water vapor leakage. Over time, it will cause a loss of antifreeze.
防冻液消耗快属于正常现象吗？
Is it a normal phenomenon for antifreeze to consume quickly?
防冻液会随着汽车的使用里程而逐渐减少，这是正常的现象。因为发动机工作的时候，会产生非常高的温度，这会让防冻液的温度也升高，一般液体温度升高后，体积会膨胀，尤其是在一个密闭的空间里，压强就会增大，防冻液的盖子上的泄压孔就会打开，防冻液就会跑出来一部分，所以防冻液慢慢减少是正常的现象。
It is normal for antifreeze to gradually decrease with the mileage of the car. Because when the engine is working, it produces a very high temperature, which also increases the temperature of the antifreeze. Generally, when the liquid temperature increases, the volume will expand, especially in a closed space, the pressure will increase, and the pressure relief hole on the antifreeze cover will open, causing some of the antifreeze to escape. Therefore, it is normal for the antifreeze to gradually decrease.
Normal loss usually affects 15% per year, and the main form of loss is natural evaporation. Without replacement, as long as it does not exceed 36%, it is normal. For more related matters, come to our website http://www.lutongqixiu.com consulting service
