我们在影视剧中经常看到这样的场面，主人公看着冒烟的发动机舱，一筹莫展。这就是人们常说的汽车“开锅”。遇到这种情况，你会怎么样呢？估计也只是把发动机舱盖打开，看着往外冒的烟干着急。有的人甚以为发动机就要爆炸，丢下车逃跑。汽车“开锅”是指由于发动机过热导致冷却液沸腾外溢的现象。如果驾驶时温度表超过正常数值，指向H附近，或者发动机舱盖里往外冒白烟，说明很有可能“开锅”了。导致过热的原因有很多，包括冷却液不足、给冷却液降温的冷却风扇故障、节温器故障、冷却液温度传感器故障等。如果应对不当，严重时会导致不菲的发动机出现故障。因此，及时发现并正确处置过热，可以有效减少损失。
We often see such scenes in movies and TV plays. The protagonist looks at the smoking engine compartment and finds nothing to do. This is what people often say about automobiles. What will happen to you in this situation? It's estimated that it's just opening the hood of the engine and watching the smoke coming out in a hurry. Some even thought the engine was about to explode and left the car to run away. Auto "boiling" refers to the phenomenon of coolant boiling overflow caused by engine overheating. If the thermometer is above the normal value when driving, pointing to the vicinity of H, or white smoke coming out of the engine hatch, it is likely to "boil". There are many reasons for overheating, including insufficient coolant, cooling fan fault, thermostat fault, coolant temperature sensor fault, etc. If not handled properly, serious problems may result in failure of expensive engines. Therefore, timely detection and correct disposal of overheating can effectively reduce losses.
风扇传动带断裂或冷却风扇拨生故阵的情祝
Love wishes for fan drive belt breaking or cooling fan pulling out the old battle
发动机熄火！
Engine stall!
风扇传动带断裂不但会使整个冷却系统瘫痪，还会导致发电机停止工作。发电机停止工作时，仪表盘上的充电报警灯会亮起来，这也是判断汽车是否过热的依据之一。如果属于风扇传动带断裂的情况，应该熄火，等待发动机自然冷却。
Fracture of fan drive belt will not only paralyze the whole cooling system, but also cause the generator to stop working. When the generator stops working, the charging alarm light on the dashboard will turn on, which is also one of the criteria for judging whether the car is overheated or not. If the fan belt is broken, it should be extinguished and wait for the engine to cool naturally.
如果在起动状态下冷却风扇停止工作（可根据风扇声音判断），那么过热的原因就有可能是冷却风扇或温度传感器出现故障。此时好等待拖车救援，或者打开空调，使用空调风扇降温，就近维修。
If the cooling fan stops working in the starting state (which can be judged by the sound of the fan), the cause of overheating may be the failure of the cooling fan or temperature sensor. At this time, it is better to wait for the rescue of the trailer, or turn on the air conditioner, use the air conditioning fan to cool down, and repair nearby.
出现以下情况时，可能会再次发生过热现象，应该等待拖车救援。
When the following situation occurs, overheating may occur again, and the rescue of the trailer should be awaited.
①风扇传动带断裂时。
When the fan drive belt breaks.
②冷却风扇在发动机温度过高的状态下仍然不工作时。
(2) Cooling fan still does not work when engine temperature is too high.
③冷却液泄漏，补充后仍然不断减少时。
(3) When the leakage of coolant continues to decrease after replenishment.
冷却风扇工作正常，风扇传动带投有断翻的情祝
The cooling fan works normally and the fan drive belt is broken.
不要关闭发动机
Don't turn off the engine
如果风扇传动带和冷却液循环都很正常，则不要熄火，停车等待发动机冷却。通常，人们都容易觉得发动机熄火后才更容易冷却，其实不然，熄火后冷却风扇和冷却液循环都会停止，这会使发动机变得更热。发动机舱保险杠一侧装有两个螺旋式风扇，一个是在发动机工作时给发动机降温的散热风扇，一个是打开空调时用的空调风扇。所以在汽车过热时如果风扇传动带没有断裂，则好不要让发动机熄火，还可同时打开空调，这样发动机降温速度会更快。
If the fan belt and coolant circulation are normal, do not turn off, stop and wait for the engine to cool down. Usually, people tend to think that it is easier to cool the engine after it goes out. Otherwise, the cooling fan and coolant circulation will stop after the engine goes out, which will make the engine hotter. There are two spiral fans on one side of the engine compartment bumper. One is a cooling fan for the engine when the engine is working, and the other is an air conditioning fan when the air conditioning is turned on. Therefore, if the fan belt is not broken when the car is overheated, it is better not to let the engine stall, but also to turn on the air conditioner, so that the engine cooling speed will be faster.
打开发动机舱盖时避免烫伤
Avoid scalding when opening engine hatch
为了让发动机更快冷却，可以打开发动机舱盖。此时，炙热的水蒸气很可能导致双手烫伤，所以不要着急，等到合适的时机再打开发动机舱盖。待发动机冷却，冷却液温度表恢复正常后可以重新起动汽车。
In order to cool the engine faster, the engine hatch can be opened. At this point, hot water vapor is likely to cause burns on both hands, so don't worry, wait until the right time to open the engine hatch. When the engine is cooled, the coolant thermometer can be restarted to normal.
发动机完全冷却后检查冷却液余量
Check coolant allowance after complete cooling of engine
如前所述，冷却液储液罐通过软管与散热器相连，很容易辨认。正常情况下，储液罐内的冷却液液面高度应该位于MAX和MIN刻度之间。如果冷却液余量正常且底板没有冷却液溅落，表明冷却液没有渗漏。如果冷却液正在渗漏，则需要等待拖车救援，就近维修（交通事故导致散热器破裂，引发冷却液泄漏，同样会使发动机过热，这种情况下也要等待拖车救援）。
As mentioned earlier, the coolant tank is connected to the radiator through a hose and can be easily identified. Normally, the coolant level in the tank should be between the MAX and MIN scales. If the coolant allowance is normal and there is no coolant splash on the bottom plate, the coolant does not leak. If the coolant is leaking, it needs to wait for the rescue of the trailer and be repaired nearby. (Traffic accidents cause the radiator to break down and cause the coolant to leak, which will also overheat the engine. In this case, it also needs to wait for the rescue of the trailer.)
冷却液不足时应及时补充
When the coolant is insufficient, it should be replenished in time
如果冷却液储液罐内冷却液不足，要打开储液罐将冷却液补充MAX和MIN的刻度之间。如果冷却液已经完全耗尽，则应打开散热器（水箱）盖，直接加入冷却液。
If there is insufficient coolant in the coolant tank, open the tank and replenish the coolant between the MAX and MIN scales. If the coolant has been completely exhausted, the radiator (water tank) cover should be opened and the coolant should be added directly.
检查发动机润滑油
Check engine lubricants
发动机润滑油不足，温度升高，严重时会引发“开锅”现象，导致发动机出现故障。检查发动机润滑油时，要先熄火，等待5min之后再拔出润滑油标尺确认。
Insufficient lubricating oil and high temperature will cause the phenomenon of "boiling" when the engine is serious, which will lead to engine failure. When inspecting the engine lubricant, it is necessary to extinguish the engine first, and wait for 5 minutes before pulling out the lubricant gauge for confirmation.
发动机降温后去维修中心检修
After engine cooling, go to maintenance center for repair
如果补充冷却液后发动机恢复正常，应该尽快去维修中心进行检修。
If the engine returns to normal after adding coolant, it should be repaired at the maintenance center as soon as possible.
