1、 The operation process when burning the engine is incorrect.

二、冷却介质缺少：①防冻液：高 档车要求一年四季都要加注防冻液；②水或蒸馏水：暂时代用；③水箱盖漏水。

2、 Lack of cooling medium: ① antifreeze: high-end vehicles are required to fill with antifreeze all year round; ② Water or distilled water: temporary substitution; ③ The water tank cover leaks.

三、水泵缺点：叶轮打滑或卡死导致正时皮带断掉；叶轮变形。

3、 Disadvantages of water pump: the impeller slips or gets stuck, resulting in the breakage of timing belt; Impeller deformation.

四、冷却电扇不转：冷却电扇或许由温控开关控制；也或许由水温传感器控制。

4、 The cooling fan does not rotate: the cooling fan may be controlled by the temperature control switch; It may also be controlled by the water temperature sensor.

五、水箱堵塞：外部堵塞应用水或气将脏物除掉；内部堵塞会影响冷却液的循环，一起会发作压力，这时会有两种效果，一种是水箱漏水，另一种是在高速行驶时水温特别高。

5、 Water tank blockage: the external blockage shall be removed with water or air; Internal blockage will affect the circulation of coolant, and pressure will occur together. At this time, there will be two effects, one is water leakage in the water tank, and the other is that the water temperature is particularly high when driving at high speed.

六、汽缸损蚀：燃烧室与水道冲，这时会从排水管排水或排白烟，构成水箱经常性缺水；水道与油道冲（机油有水呈白色）；水道与水道冲，构成缸体散热不良，尤其在高速时影响更大。

6、 Cylinder erosion: when the combustion chamber and water channel are flushed, water will be drained or white smoke will be discharged from the drain pipe, forming a frequent water shortage in the water tank; Water channel and oil channel flushing (the oil is white with water); The water channel and water channel scour constitute poor heat dissipation of the cylinder block, especially at high speed.

七、节温器损坏：如想拆掉节温器，此时应把小循环堵上，这样可以保证冷却液全部由水箱散热；装新节温器时应留心是否有过水孔。

7、 Thermostat damage: if you want to remove the thermostat, block the small circulation at this time, so as to ensure that all the coolant is dissipated by the water tank; When installing a new thermostat, pay attention to whether there is a water hole.

假设在驾御的时分发现了水温过高就要靠边泊车，但不要当即熄火。因为冷却液的温度现已很高，降温才干已达到上限，这时假设当即熄火，欢娱的冷却液也就间断了循环。过高的温度得不到冷却，发起机也是难以承受的。假设先让发起机怠速作业一会儿，不断循环的冷却液仍是可以减轻高温对发起机的影响。

If you find that the water temperature is too high during driving, you should pull over and park, but don't turn off the engine immediately. Because the temperature of the coolant is now very high and the cooling ability has reached the upper limit, it is assumed that the engine will be shut down immediately, and the happy coolant will stop circulating. Too high temperature can not be cooled, and the starter is also unbearable. If the engine is allowed to idle for a while, the circulating coolant can still reduce the impact of high temperature on the engine.

小型混凝土自动搅拌车水温过高的核心原因大概为上面介绍的内容，还有就是必定要留心在水的温度过高情况下千万千万不要灭火，否则就会对发起机构成损害。

The core reason for the high water temperature of the charging mixer is probably the content introduced above. In addition, we must pay attention not to put out the fire when the water temperature is too high, otherwise it will cause damage to the initiator.
