Common faults and troubleshooting methods of car cooling fan

Mar. 14, 2018

With the development of science and technology, people walking tools are more and more advanced, at any time today, the car because of its space comfortable, driving stability and high performance price ratio, and has become the mainstream of our transportation, auto cooling failure has become a more and more attention of our business, so what are the common faults automobile cooling fans, to how to repair and eliminate?

The fault

1. Does the car have a cooling fan during the exercise?

The reason:

1; The engine water temperature does not reach the cooling fan starting condition, the temperature is low.

2; The cooling fan can be tested with an engine diagnostic instrument. If the cooling fan can rotate normally, the line is normal and the thermostat is checked.

2. The car cooling fan does not turn on the air conditioner and does not refrigerate.

The reason. First check the electronic fan temperature control switch, the switch can check the failure of the electronic fan itself, and the electronic fan can heat the air conditioner evaporator to cool the air conditioning system.

3. The car engine cooling fan does not turn.

The reason is that the high water temperature of the engine is mainly caused by the failure of the electronic fan, and the water temperature will be normal after the failure of the electronic fan. Electronic fan doesn't work first check the plug is bad contact, check the power supply and take iron condition of electronic fan, check whether the fan is binding, check whether the fan motor is burning, etc., these factors will lead to the electronic fan can't start, suggest vehicles in a timely manner to the 4 s shop repair, after the troubleshooting on the road.

4. The air conditioning cooling fan is loud.

The reason is to check whether the fan has a grinding case, check whether the fan page is deformed, and whether the bearing is damaged or not, whether the fan has foreign body to enter.

5. After quenching, the cooling fan starts frequently.

The reason is to cool the engine.

The cooling system also stops after the normal car is extinguished, which often causes the engine to turn off and the temperature increases, causing damage. So now the high-grade car set up automatic cooling function, the power of the radiator is directly to the battery, remove from the engine temperature is still high, so the cooling fan is still working for a period of time, after waiting for temperature cooling stalling again, in order to avoid high temperature cause car spontaneous combustion.
