What is the reason for the high temperature alarm when Chery QQ car is at low idle speed?

I have been in this situation. Please check whether the fan is running. Check the way to turn on the air conditioner when the engine is idling. At this point, the fan will be forced to start. If the fan does not turn after turning on the air conditioner, there are only two possibilities: the fan is damaged or the fan fuse is blown. In most cases, the fuse is blown. When driving, the water temperature will not be too high because the wind cools and the water tank enters a large cycle. I once drove back to Shanghai from Jiangyin under such circumstances.

Another possibility is that your water tank is short of water. Check the scale of the kettle.
