What is the reason why the 2010 1 8t Magotan cooling fan keeps turning

Hello, there are several situations when the fan often turns.

1.If the fan is still turning, check the second step, if it does not turn, replace the temperature switch.

2.There is a short-circuit in the fan line to the positive pole.

Check for line issues.

3.The water temperature sensor is damaged or the wiring is faulty, and the computer keeps letting the fan cool down in order to protect it!

Under normal circumstances, when the car stops in place after starting the engine, the water temperature will rise rapidly, and the cooling fan will be activated frequently to prevent it"；Bring to a boil"；In low-speed driving, such as traffic jams, stop-and-go, the fan will also start as often, the reason is the same as above, if the vehicle is driving at medium and high speeds, because the speed is fast, the coolant can be fully cooled, the fan will not start, and in this state, the fan is started in time, because of the existence of various noises, ordinary people will not notice, so I judge that you should hear the sound of the fan for the first two reasons.

I suggest you go to the repair shop to check your fan relay, maybe it is damaged, or it has come into contact with **? Causing your car, the fan has been spinning, I hope mine is helpful to you, I wish you a happy drive [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The fan module is broken. Replacement can be solved. Engines generally use internal combustion engines, which do their work through the heat energy generated by combustion.

However, the effective power is only 30% to 40% of the total energy of the fuel, and the remaining energy is consumed as exhaust heat loss and mechanical friction heat loss. Especially in order to maintain the proper temperature of the cylinder, cylinder head, intake and exhaust valves.

The role of the heater fan:

The automobile radiator is composed of three parts: the water inlet chamber, the water outlet chamber and the radiator core. The coolant flows inside the radiator core and air passes through the radiator. The hot coolant cools down as it dissipates heat to the air, and the cold air heats up by absorbing the heat emitted by the coolant.

When a car is driven, the heat generated by the engine is enough to destroy the car itself. Therefore, a cooling system is installed on the car to protect it from damage and keep the engine within the proper temperature range.

1. Check whether the electronic fan is working normally, under normal circumstances, the electronic fan has two gears, one is a low-speed gear, and the other is a high-speed gear, the high-speed gear generally works when the air conditioning pressure is too high and the water temperature of the engine reaches 103 degrees Celsius.

If the car electronic fan does not have high speed or the speed of high speed is not enough, the above phenomenon will definitely occur. It should be noted that if the electronic fan does not have high speed, it is not necessarily the problem of the electronic fan, the high-speed insurance of the electronic fan is in the fuse box on the battery, if the insurance is burned, the line contact of the insurance is not real, the high and low voltage switch of the air conditioner is damaged or the fan high-speed relay is damaged, it will lead to the electronic fan without high speed.

2. Check whether the opening of the thermostat is insufficient, the thermostat will be too small at normal temperature, which will lead to the slow circulation speed of the cooling water of the engine, which will lead to the phenomenon of high water temperature at low speed.

3. Check whether the pump is idling. The Jetta avant-garde water pump impeller is plastic, and if the shaft is listed, it will cause idling when the water temperature is high, resulting in high water temperature.

Summary. Hello, the fan often rotates for three reasons, the first reason is that the fan module is damaged, after closing the key door, the fan will still turn, in this case, the replacement of the fan will always work, the second reason is that the water temperature sensor is abnormal, check whether the water temperature signal is too high, or the engine does have a high temperature, if the temperature is high, you need to replace the thermostat, the third reason is that there is a problem with the engine computer itself, or the fault caused by the high pressure of the air conditioning pipeline. There is a time limit for the first reply, if you have any questions, you can reply and answer them in detail.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

Hello, the fan often rotates is caused by three reasons, the first reason is that the fan module is damaged, after closing the key door, the fan will still turn, in this case, the replacement of the fan is always OK, the second reason is that the water temperature sensor is abnormal, check whether the water temperature signal is too high, or the engine of the group does have a high temperature, if the temperature is high, the thermostat needs to be replaced, the third reason is that the engine computer itself has a problem, Or it is a fault caused by the pressure of the air conditioning line is too high. There is a time limit for the first reply, if you have any questions, you can reply and answer them in detail.

The fact that the fan keeps turning proves that the thermostat has always thought your engine is hot. That is to say, either the engine temperature of your source state itself is higher than the sail crack letter fan starting line. Or maybe the sensor is incorrectly.

However, considering that you have changed the antifreeze to have such a situation, I guess the quality of the antifreeze is not good. The heat conduction and heat dissipation effect is not as good as before, which is caused by high machine temperature.

What's the deal with the Magotan fan that keeps turning? What's the deal with the Magotan fan that keeps turning? Volkswagen Magotan fans keep turning for the following reasons:

1. Insufficient cold water: The engine is overheated due to insufficient cooling water, and the electronic fan continues to run. 2. Water tank leakage:

The engine is overheated due to a leaking water tank, the hose is loose or damaged, and the electronic fan is constantly running. 3. Thermostat failure: due to the thermostat, the temperature reaches the benchmark temperature and cannot send water to the water tank, or the amount of water is too small, resulting in overheating of the engine and continuous operation of the electronic fan.

Note: The fan of Magotan car is based on the water temperature and engine load, and the signal is transmitted to the computer, and the engine computer controls the high and low speed relays of the fan to control the operation of the fan, and it is also affected by the pressure of the air conditioner. @2019

Summary. Hello, this problem is the fault caused by the damage of the fan control module, when the module itself is damaged, or the water temperature signal, the pressure signal of the air conditioning pipeline, the oil temperature signal and the engine load are too large will enter the protection state, so that the fan has been rotating to avoid the engine overheating, you can first check whether there is a problem with the fan module itself, after eliminating the fan fault, use the diagnostic instrument into the engine and the air conditioning computer to read the above temperature, pressure, engine load data flow, and find that the sensor is damaged and replaced.

Hello, this problem is the fault caused by the damage of the fan control module, when the module itself is damaged, or the water temperature signal, the pressure signal of the air conditioning pipeline, the oil temperature signal and the engine load will enter the protection state, so that the fan has been rotating, to avoid the engine failure and overheating, you can first check whether there is a problem with the fan module itself, after eliminating the fan fault, you can detect that Li uses the diagnostic instrument into the engine and the air conditioning computer to read the data flow of temperature, pressure, and engine load on the land, If the sensor is found to be damaged, it can be replaced.

I read the data stream, the intake air temperature shows -40 degrees, and also reports this fault code, will it affect the fan to rotate often?

Ask about custom messages].

If it is affected, solve the fault code first after there is a fault code, and then check the fan module and communication line.

Hello dear<> it's a pleasure to thaw you. 07 Magotan electronic fan how many degrees to rotate. 07 Magotan electronic fan 90 degree rotation.

The working principle of the electronic fan is that the car electronic fan is controlled by the thermostat, when the water temperature rises to the upper limit value of the thermostat is connected to the power supply, the fan starts to work, and when the water temperature is reduced to the lower limit value of the thermostat turns off the power supply, the fan stops working. The following are the reasons why the electronic fan does not rotate: 1. The motor lubrication is poor, and the electric fan does not rotate, because the lubrication of the motor is not good, resulting in the motor not being able to drag after the fan blade is installed and transported; 2. The motor is overheated, and the overheating of the motor will also cause the load capacity of the motor to deteriorate, and the effective power of the motor will become low, resulting in the inability to drive the load; 3. The starting capacitance capacity becomes smaller, and the capacitor capacity will become smaller, resulting in the starting torque of the motor becoming smaller, and the load cannot be driven; 4. If the motor is used for too long, if the electric fan is used for a long time, the motor will be lost, and the shaft sleeve of the motor will be worn out, and it will be easy to burn off.

If the motor is used for a long time, it will also increase the internal resistance of the stove-resistant motor and reduce the load capacity, resulting in the inability to drive the fan blade to rotate. <>
