What is the reason why the automobile cooling fan does not turn?

According to Bian Xiao, many friends don't know much about cars. For example, many people have asked the problem that the automobile cooling fan does not turn. If you want to know, please read Bian Xiao's introduction below, hoping to inspire and help you.

The non-rotation of automobile cooling fan may be caused by the blockage of air conditioning filter element, insufficient refrigerant or the blockage of warm air water tank.

First of all, you need to check whether the filter element of the air conditioner is blocked. If the cooling fan is not running, the water temperature of the engine will rise. At present, the cooling fans used in automobiles all adopt electronic temperature control. Only when the water temperature reaches a certain requirement will the cooling fan work normally. If the water temperature meets the requirements, the cooling fan does not turn, indicating that the relay of the cooling fan is faulty.

It is also possible that the temperature control switch fails, which will also have a certain impact on the cooling fan of the car, so it should be checked regularly. http://wWw ./

The water temperature relay is damaged, usually due to poor line contact or fault. If there is no response, the relay needs to be replaced directly. If the temperature control switch is damaged, the water temperature in the car will rise and the cooling fan will not be energized normally. If the fan is damaged, the load generated by the fan may be too large, or the line of the fan may be short-circuited. If there is something wrong with the line, you need to check it carefully. If it doesn't work, replace it with a new one.

Radiator is very important to engine, which is related to driving safety. If something goes wrong, it must be repaired in time.
