近有車友抱怨：幾天沒開車早上開車時發現防凍液沒了，那么消失的防凍液去哪兒了？下面
濟南奔馳汽車維修廠家就為大家解開“防凍液消失之謎”！
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!

冷卻系統滲漏
Cooling system leakage
冷卻系統有很多部位可能發生滲漏，比如水管、水堵等。一般情況下，滲漏都是比較容易發現的。可是有些部位的滲漏，由于特別輕微，比較難發現，只要我們認真觀察，一定能夠找到滲漏的部位，然后我們對癥下藥，把相應的部位緊固或者重新安裝就好了。
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.

水箱蓋損壞
Damaged water tank cover
冷卻系統上的水箱蓋并不是普通的蓋子，而是在其內部帶有空氣閥和蒸汽閥的特制蓋子。如果這個蓋子出現了故障，特別是蒸汽閥開啟壓力過低或者處于常開位置，就會導致大量的水蒸氣從這兒漏出，時間長了防凍液就會缺失，這是防凍液缺失的主要原因。
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.

防凍液不符合使用標準
The antifreeze does not meet the usage standards
現在汽車發動機工作溫度都在90~105°C之間，為了避免防凍液沸騰，防凍液的沸點一般都在108°C以上，同時它的蒸發量也會受到嚴格的限制。如果防凍液不符合使用標準，會導致領取系統內部壓力過大，將蒸汽閥頂開，水蒸氣泄漏，久而久之就會造成防凍液缺失。
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.
防凍液消耗快屬于正常現象嗎？
Is it a normal phenomenon for antifreeze to consume quickly?
防凍液會隨著汽車的使用里程而逐漸減少，這是正常的現象。因為發動機工作的時候，會產生非常高的溫度，這會讓防凍液的溫度也升高，一般液體溫度升高后，體積會膨脹，尤其是在一個密閉的空間里，壓強就會增大，防凍液的蓋子上的泄壓孔就會打開，防凍液就會跑出來一部分，所以防凍液慢慢減少是正常的現象。
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.cnjqf.com consulting service
