老話說的“五油三水”是保養維修中常見的幾個液體，冷卻液就是三水中的一員，就像人體不能缺水一樣，汽車也少不了冷卻液，不然也發動機很容易開鍋。所以，當車主遇見寶馬車顯示加注冷卻劑的提示，大多也是手足無措，不懂怎么處理，下面就濟南哪里有寶馬汽車維修的廠家來講一下這個問題。

As the old saying goes, "five oil and three water" is a common liquid in maintenance and repair. Coolant is one of the three water. Just like the human body cannot lack water, cars cannot lack coolant, otherwise the engine is easy to boil. Therefore, when the car owner meets the prompt of adding coolant displayed by BMW, most of them are at a loss and don't know how to deal with it. Next, let's talk about where there is a BMW maintenance manufacturer in Jinan.

方法/步驟

Method/step

1、是否誤報

1. False alarm or not

這個一般是液位傳感器及其相關線路的問題。要看是不是誤報，我們只能手動打開冷卻液蓋，實際的觀察液位是否正常。

This is generally the problem of the liquid level sensor and its related circuits. To see if there is a false alarm, we can only open the coolant cap manually and observe whether the liquid level is normal.

2、發動機冷卻

2. Engine cooling

車子停放在水平地面，等發動機冷卻。

The car is parked on the level ground, waiting for the engine to cool down.

3、點火

3. Ignition

車子進入點火狀態。

The car enters the ignition state.

4、檢查水溫

4. Check water temperature

冷卻系統經過加壓，只能等發動機完全冷卻以后才能擰開水箱蓋。冷卻液溫度表必須顯示低于70°C，否則可能會被溢出的高溫冷卻液燙傷。

The cooling system is pressurized, and the water tank cap can only be unscrewed after the engine is completely cooled. The coolant temperature gauge must display below 70 ° C, or you may be scalded by the overflowing high temperature coolant.

5、加注口操作

5. Filler operation

用塊布放在防凍液加注口的蓋子上，逆時針旋轉加注口半圈，釋放剩下的壓力。

Place a cloth on the cover of the antifreeze filler, and turn the filler counterclockwise for half a turn to release the remaining pressure.

6、觀察

6. Observation

再旋轉加注口，直至取下蓋子；如果冷卻液在冷態時與加注口上的標示棒齊平或在熱態時高出約1.5厘米，則表示水箱內有足夠的冷卻液。

Then rotate the filler until the cap is removed; If the coolant is flush with the marking rod on the filler opening when it is cold or about 1.5 cm higher when it is hot, it means that there is enough coolant in the water tank.

7、冷卻液真的少了

7. The coolant is really low

冷卻液是各種添加劑和蒸餾水的混合物，水會蒸發，所以，隨著用車公里數的增加，冷卻液確實會有所消耗。

The coolant is a mixture of various additives and distilled water, and the water will evaporate. Therefore, with the increase of vehicle mileage, the coolant will indeed be consumed.

那這里就有問題了，到底是正常消耗？還是冷卻系統泄漏？這個只能提示“加注冷卻劑”后，我們加滿冷卻液，然后再觀察，如果短期再提示，說明不是正常消耗。更多相關汽車維修保養事項就來我們網站http://www.cnjqf.com咨詢看看吧！

Then there is a question. Is it normal consumption? Or is the cooling system leaking? This can only prompt that after "adding coolant", we fill up the coolant, and then observe. If we prompt again in a short time, it means that it is not normal consumption. Come to our website for more information about car maintenance http://www.cnjqf.com Consult and see!
