添加发动机冷却液的步骤，请问发动机冷却液怎么加？

添加发动机冷却液的步骤

1、拧下水箱盖，打开水箱放水阀，放出防冻液。

2、将一根连接于自来水管的橡胶管插入水箱加水口，打开自来水，使自来水连续不断地流经发动机冷却系统。在冲洗操作时，要使发动机怠速运转，直至水箱放出清水为止。

3、关上自来水龙头，待冷却系统的水放尽后，再关上水箱放水阀。

4、从水箱加水口加人防冻液，使防冻液充满水箱。拧开储液罐盖，加人防冻液，并达到“Max”刻度线，注意不要超过“Max”刻度线。

5、盖上水箱盖和储液罐盖，并拧紧。

6、起动发动机，怠速运转2～3 min，拧开水箱盖。这时冷却系统由于排除了部分空气，防冻液面将降低，这时应再补充防冻液，使防冻液达到“Max”刻度线为止。

【英文介绍/For English】：

1. Unscrew the water tank cover, open the water tank drain valve, and release the antifreeze.

2. Insert a rubber tube connected to the tap water pipe into the water tank filling port, turn on the tap water, and make the tap water flow through the engine cooling system continuously. During the flushing operation, run the engine at idle speed until the water tank releases clean water.

3. Close the tap, and after the water in the cooling system is drained, close the water tank drain valve.

4. Add antifreeze from the water tank filling port to fill the water tank with antifreeze. Unscrew the lid of the reservoir tank, add antifreeze, and reach the "Max" mark, be careful not to exceed the "Max" mark.

5. Cover the water tank cover and the liquid storage tank cover and tighten them.

6. Start the engine, run it at idle speed for 2-3 minutes, and unscrew the water tank cover. At this time, since the cooling system removes part of the air, the antifreeze level will decrease. At this time, the antifreeze should be replenished until the antifreeze reaches the "Max" mark.

发动机冷却液怎么加

发动机冷却液是汽车引擎中必不可少的组成部分，它具有以下几个作用：

1. 发动机散热：发动机在运行时会产生高温，如果温度过高会导致部分零件损坏，严重的话甚至会引发火灾。冷却液通过流动在发动机中，从而将散热器中吸收到的热量带走。

2. 防止冻裂：在低温环境下，水在结冰时会膨胀，如果在发动机中存在水或水质冷却剂，在冬季时间，如果没有冷却液，就会导致发动机出现冻裂现象。

3. 防腐抗蚀：冷却液中添加一些化学成分，使其具有防腐抗蚀的性能，避免因为杂质的污染而对发动机产生不良的影响。
