How to repair the broken car fan?

Maintenance method of automobile fan in Pacific Auto Network: The cooling fan can be detected by engine diagnostic instrument. If everything is all right, the mechanic needs to check whether the thermostat is out of order.

Driving in summer, in addition to always paying attention to road conditions, you also need to endure hot and high temperatures. At this time, if the radiator fan of the car fails, it will be terrible! On the other hand, after the radiator fan has a problem, how should the mechanic repair it? What Bian Xiao brings to you today is the troubleshooting method for the fan of automobile radiator. This article is full of work, so don't be distracted.

Question 1: The cooling fan does not operate and maintain when the car is driving. This problem may be that the engine water temperature does not meet the starting conditions of the cooling fan. Machinists can use engine diagnostic instruments to test the cooling fan. If everything is all right, the mechanic needs to check whether the thermostat is faulty.

Question 2: It is normal to start the cooling fan frequently after the car is turned off. Because the cooling system usually stops working after the car is turned off, and the temperature of the engine has not cooled down at this time, the cooling fan will continue to work for a while, and only when the temperature of the engine drops down will the cooling fan stop working naturally.

Problem 3: The fan does not turn when the gear is high. First, the mechanic should check whether the plug of the fan is in poor contact. In addition, check the power supply of the fan and whether the fan is stuck. These factors will cause the fan not to work at high gear.

Question 4 Abnormal noise of the fan If you hear abnormal noise when the fan is working normally, there are four situations:

1. The fan penetrates the shell;

2. The fan bearing may be damaged;

3. The fan blade is deformed;

4. Foreign matter has entered the fan.

In the above four cases, the first three cases need to replace the relevant parts, and the last case only needs to clean up the foreign objects.

After knowing how to solve the radiator fan, you also need to know how to disassemble the radiator fan correctly so as not to damage it. The following is the correct removal procedure of radiator fan:

1. Remove the engine lower baffle;

2. Remove the auxiliary water tank;

3. Panasonic coolant pipe;

4. Remove the buckle on the fan cover;

5. Remove the connecting plug and take out the fastening screw of the fan cover;

6. Remove the fixing nut of the fan.
