老话说的“五油三水”是保养维修中常见的几个液体，冷却液就是三水中的一员，就像人体不能缺水一样，汽车也少不了冷却液，不然也发动机很容易开锅。所以，当车主遇见宝马车显示加注冷却剂的提示，大多也是手足无措，不懂怎么处理，下面就
济南哪里有宝马汽车维修的厂家来讲一下这个问题。
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/步骤
Method/step
1、是否误报
1. False alarm or not
这个一般是液位传感器及其相关线路的问题。要看是不是误报，我们只能手动打开冷却液盖，实际的观察液位是否正常。
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、发动机冷却
2. Engine cooling
车子停放在水平地面，等发动机冷却。
The car is parked on the level ground, waiting for the engine to cool down.
3、点火
3. Ignition
车子进入点火状态。
The car enters the ignition state.
4、检查水温
4. Check water temperature
冷却系统经过加压，只能等发动机完全冷却以后才能拧开水箱盖。冷却液温度表必须显示低于70°C，否则可能会被溢出的高温冷却液烫伤。
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
用块布放在防冻液加注口的盖子上，逆时针旋转加注口半圈，释放剩下的压力。
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、观察
6. Observation
再旋转加注口，直至取下盖子；如果冷却液在冷态时与加注口上的标示棒齐平或在热态时高出约1.5厘米，则表示水箱内有足够的冷却液。
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、冷却液真的少了
7. The coolant is really low
冷却液是各种添加剂和蒸馏水的混合物，水会蒸发，所以，随着用车公里数的增加，冷却液确实会有所消耗。
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.
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.lutongqixiu.com Consult and see!
