"The engine of a concrete mixer truck overheats, which is commonly referred to by driver friends as running at high temperatures. Running the engine at high temperatures is not good, and bad luck can cause the engine to fail.".

1、如果在普通公路上发动机出现了过热，应该尽快地降低车速，把搅拌车驶到树荫下，或驶到相对比较凉快的地方，将小型搅拌车停下来。打开发动机罩盖，让发动机怠速运转，等待发动机温度逐渐恢复正常。

1. If the engine overheats on an ordinary highway, you should reduce the speed as soon as possible, drive the mixer truck into the shade of a tree, or drive to a relatively cool place, and stop the small mixer truck. Open the engine hood and allow the engine to idle, waiting for the engine temperature to gradually return to normal.

在发动机水温恢复正常之后，将发动机熄火。然后再等待一段时间，直到发动机的水温充分地下降了之后，再检查发动机的冷却水量。这时发动机的冷却水量大都严重不足。按着规定量把冷却水补足之后，再检查一下冷却系统，确认没有其他故障之后，可以起动发动机，继续行驶。

After the engine water temperature returns to normal, turn off the engine. Then wait for a further period of time until the water temperature of the engine has dropped sufficiently, and then check the cooling water volume of the engine. At this time, the cooling water volume of the engine is mostly seriously insufficient. After replenishing the cooling water according to the specified amount, check the cooling system again and confirm that there are no other faults. After that, start the engine and continue driving.

2、如果在高速公路上出现了发动机过热，需要立刻把暖风全部打开并打开车窗。由于有暖风帮助冷却水散热，能使冷却水温大幅度地下降。

2. If the engine overheats on a highway, it is necessary to immediately turn on all the heating and open the windows. Due to the help of warm air to dissipate heat from the cooling water, the cooling water temperature can significantly decrease.

这样可以持续开车，就近找到高速公路的出口，将搅拌车驶到一定的场所停下来。接下来，只要按照上述的方法，使发动机的温度降下来就行。注意，好不要把搅拌车停在路边，以免影响交通或被撞车，把小型搅拌车停在的场所。

This allows you to continue driving, find the exit of the highway nearby, and drive the mixer truck to a certain location to stop. Next, just follow the above method to lower the temperature of the engine. Be careful not to park the mixer truck on the roadside to avoid affecting traffic or being hit by a car. Park the small mixer truck in a place.
