1、 Incorrect operation when burning the recommended vehicle.

二、冷却介质缺少：①防冻液：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: Advanced vehicles require antifreeze to be filled all year round; ② Water or distilled water: temporarily substituted; ③ The water tank cap is leaking.

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 a broken timing belt; Impeller deformation.

四、冷却电扇不转：冷却电扇或许由温控开关操控；也或许由水温传感器操控。

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

五、水箱阻塞：外部阻塞应用水或气将脏物除掉；内部阻塞会影响冷却液的循环，一起会发生压力，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 clogging: external clogging should be removed with water or gas; Internal blockage can affect the circulation of the coolant and together, pressure can occur. There are two effects: one is water leakage in the water tank, and the other is particularly high water temperature during high-speed driving.

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 is flushed with the water channel, it will drain water or discharge white smoke from the drain pipe, resulting in frequent water shortage in the water tank; Water channel and oil channel flushing (the engine oil is white with water); The water channel and the water channel are flushed, resulting in poor heat dissipation of the cylinder block, especially at high speeds.

七、节温器损坏：如想拆掉节温器，此时应把小循环堵上，这样能够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, you should plug the small circulation at this time to ensure that all cooling liquid is dissipated by the water tank; When installing a new thermostat, pay attention to whether there are water holes.
