The water temperature of the car is not high, and the electronic fan often turns how to check

At present, there are three kinds of domestic automobile fans, electronic fans, silicone oil fans, electromagnetic clutch fans, electronic fans are generally used in passenger cars such as cars, and the latter two are generally used in commercial vehicles such as buses and trucks. However, the principle is to control the fan power supply according to the engine circulating water temperature signal transmitted by the outlet water temperature sensor.

If the coolant level is normal, it is generally a problem with the outlet water temperature sensor connected to the fan, especially the mono fan, which works entirely on the temperature signal.

If it is a commercial vehicle, or it can be confirmed that it is a silicone oil fan or an electromagnetic clutch fan, then in addition to checking the water temperature sensor, there is also a check whether the fan itself can be separated and suction is normal, and it is best to go to the 4S store to diagnose it, and the general vehicle diagnostic instrument can quickly find the problem.

Normally, the engine temperature is still very high after the ignition is turned off, so the electronic fan will continue to work for a period of time to dissipate heat from the engine, so there is no need to worry. If it keeps turning, it is necessary to check the water temperature sensor and related wiring problems.

Hello! Check whether the sensor is damaged first, and then check whether the speed switch of the electronic fan itself is out of order. FYI.

The electronic fan automatically senses that the water temperature reaches 93 degrees Celsius and starts working. The electronic fan works normally, and if it doesn't, it doesn't work properly.

Hello. It's the water temperature sensor that's wrong. Hope it helps.

There should be nothing wrong, don't worry about going to the car repair office to let someone else check it.

If the temperature of the lower water pipe is low and the upper water pipe is very hot, it is basically determined that the circulation is slow, resulting in slow external circulation, the opening and closing degree of the thermostat is not enough, and the impeller of the water pump is damaged.

The car engine fan keeps turning, and the water temperature is not high; Generally, there are two reasons: one is caused by the damage and failure of the thermostat, the thermostat is a valve that controls the flow path of the coolant, and it is also an automatic temperature control device, the thermostat is to maintain the engine temperature, and the fan will not stop when the thermostat fails; Second, because the engine coolant is insufficient or leaking, the engine car fan keeps rotating, and when the coolant leaks out, the engine will rise; The normal water temperature of a car is around 90.

In addition, if there is a problem with the fan, it will also lead to long-term non-stop rotation, and the general car fan will not keep rotating all the time, if it still does not stop rotating for a long time after turning off, it means that there is a problem with the fan; For electronic fans, circuit failures cause the electronic fans to rotate constantly; In the case of silicone oil fans, damage to the silicone clutch will also cause the fan to rotate constantly. These faults can lead to low water temperatures.

Question: The car turns off and the key doesn't turn.

Ask if Cruze is an electronic thermostat.

The temperature of the water in the car is not high, but the temperature of the engine is high, and it can be observed that it will not turn after dissipating the heat for a while.

Hello friends, the electronic cooling fan is based on the water temperature, and after reaching the set temperature, it has been rotating; Reference.

The temperature sensor or fan circuit is broken. Find an experienced master to check carefully.

If the water temperature is not high, you have to turn it, and if the engine is overheated, you have to turn it.

It's custom designed! Unless the thermostat is broken!!

The elimination steps for the water temperature of the car engine to reach 90 degrees and the electronic fan does not rotate are as follows:

First of all, check whether the engine water temperature sensor is faulty, the water temperature sensor failure will cause the ECU computer board to not receive the signal of high engine water temperature.

Secondly, check whether the engine temperature control switch is faulty, the temperature control switch failure will cause the electronic fan to fail to open.

Then check whether the engine electronic fan is faulty, the internal short circuit of the electronic fan will directly cause the electronic fan not to work.

Finally, check the ECU (central control computer board) of the car, which is the "brain" of the car. ECU failure can lead to the occurrence of various malfunctions of the vehicle.

Hello, why is the water temperature in my car not high, and the fan clutch is always on.

Hello, this depends on whether the fan can be stopped, if it keeps rotating, the corresponding seat can be solved by checking several aspects.

Hello, this normal water temperature is about 90 degrees, the fan of this vehicle is turned on as a thermostat, it will open normally when it reaches about 82 to 87 degrees, and after the water temperature drops, this fan will turn off, then there is no problem with this.

If the water temperature is not high, it is always open, and when you drive a car, it is very noisy.

If you don't have the air conditioner on, keep it on. Then this is generally not good heat dissipation, you can first clean up the dirt on the surface of the water tank and condenser!

If there is no temperature in the morning, it is also turned on, and the temperature is also open until the temperature is around 80. After running for about 400 kilometers, it is closed.

This situation is not normal, and it is necessary to check the water temperature sensor.

It doesn't hurt the engine much! I'll go to the service station and check it out when I get home. Thank you, teacher.

Hello friends, this doesn't interfere much with the engine, as long as the water temperature is not high! Hello, happy family, I hope mine can help you Happy driving, happy Year of the Tiger, please give a thumbs up after the conversation! Your likes are very important to me, thank you very much! 

Hello: Need to check the electronic fan controller.

The normal water temperature of the car means that the fan has been rotating is normal, the fan is divided into low-speed fan and high-speed fan, and it is normal to start the engine and rotate the low-speed fan.

The reason why the electronic fan does not turn and the water temperature is high is that the plug is faulty. The car electronic fan is controlled by a thermostat, and the electronic fan is to control the engine water temperature can not be too high, it is composed of sensors, electronic fans, chips, etc. The water temperature is generally more than 90 degrees, the sensor acts, and the electronic fan is turned on to reduce the water temperature.

When the water temperature drops to the lower limit, the thermostat turns off the power and the fan stops working. Here's how to replace the cooling fan:

1. Open the hood of the car first and remove the air intake pipe located on the top of the cooling fan, so that the cooling fan can be removed smoothly;

2. The cooling fan and the air conditioning fan are located on the fan frame, with a total of four corners, each corner has a screw, use a professional tool to unscrew these four screws;

3. When all the screws are unscrewed, you can remove the cooling fan from the car;

4. Install the new cooling fan correctly on the new fan holder, screw it well, and fix the four screws at the four corners;

5. Next, start the engine to test whether the fan can operate normally, check that it is correct, and then install the intake pipe to the correct position.

The specific reason why the car fan does not turn:

1. The water temperature does not meet the requirements: the car radiator fan uses electronic temperature control to work, so generally only when the water temperature in the car reaches the required temperature, the fan will start to rotate normally, if the temperature is too low, the radiator fan will not be able to rotate.

2. Long-term wear: The fan will be used for too long and will cause serious wear, because the motor will be lost, and the shaft sleeve of the motor will be easily burned out after wearing.

3. Motor overheating: There is a motor in the fan device, and there is an overheating circuit breaker in the motor, if there is a short circuit in the coil winding, the heat will increase in a short time, resulting in the motor not rotating.

The high water temperature of the engine is mainly caused by the electronic fan not starting, the water temperature will be normal after the electronic fan troubleshooting, the electronic fan does not work, first check whether the connector is in poor contact, check the power supply and tie of the electronic fan, check whether the fan is stuck, check whether the fan motor is burned, etc., these factors will cause the electronic fan to not start.

Reasons why the tank temperature is high but the fan doesn't turn:

1.Whether the water temperature meets the requirements: Most of today's car radiator fans use electronic temperature control to work, so generally only when the water temperature in your car reaches the required temperature, the fan will start to rotate normally, if the temperature is too low, the radiator fan will not be able to rotate.

Therefore, when your car radiator fan does not rotate, you should first check whether the water temperature meets the requirements.

2.Relay failure: If the water temperature meets the requirements and the car radiator fan still does not work, then there may be a problem with the relay of the fan, if the relay fails, the car radiator fan will not work.

3.There is a problem with the temperature control switch: if there is no problem in the above two aspects, then you have to check the temperature control switch, this place sometimes has some faults, which will also have a certain impact on the operation of the car radiator fan, so you should also pay attention to check.

When the temperature of the battery pack is below 45, use a radiator to cool down, which can save system energy consumption; When the temperature is above 45, the compressor is used to cool down and quickly dissipate heat to ensure that the battery system can work continuously and stably for a long time in the range of -40 60. Regarding the life of electric vehicle batteries, in the years of development of electric vehicles, the core proposition of electric vehicles is generally range and battery life. For fuel vehicles, the life of the whole vehicle can be more than 15 years, and for automobile manufacturers, the general evaluation of the service life of the car is measured by the number of kilometers, and the current mainstream manufacturers design the service life of the car is about 300,000 kilometers, the number of years.

Since there are one or two low-voltage batteries in the car, in order to distinguish them, the high-voltage batteries are called power batteries, which is also an industry term. Similar to the role of the fuel tank of traditional automobiles, as the "energy" of new energy vehicles, the power battery system is usually composed of battery cells, battery packs, battery management systems, cooling systems, high and low voltage wiring harnesses, protective shells, and other structural parts.

During actual vehicle use, the battery.

From the above introduction, we know the importance of power battery temperature control technology. It can be said that the temperature control method of electric vehicle batteries is really a mystery, and it is indispensable for safety and efficiency. In this issue, we focus on several basic cooling system modes commonly used in the industry, and we can find that in the next period of time, the water cooling mode will be popular.

The 48V power system can store more power than the 12V power system, and the engine can be turned off for a long time in a car equipped with a start-stop system, reducing the situation where the battery is too low and the engine is started and charged frequently (if it is not recharged, the engine cannot be used), so as to avoid wasting too much fuelOf course, the emergence of the 48V system does not mean that the 12V system has been replaced by ...

The engine water temperature is high, the main fan does not start, and the water temperature is normal after eliminating the fan fault. If the fan is not working, first check whether the connector is in poor contact, check the fan power supply and grounding, check whether the fan is stuck, and check the fan motor. Regardless of burning, etc., some.

The reason why the temperature of the water tank is high but the fan does not rotate: 1. The thermostat is not faulty, the water temperature above and below the water pipe is the same but the fan does not rotate, and the water temperature sensor may be damaged; 2. The fan itself is damaged; 3. The fan power cord is not in good contact; 4. Water shortage in the water tank; 5. The thermostat is damaged. The radiator in the engine water cooling system is composed of three parts: the water inlet chamber, the water outlet chamber, the main piece and the radiator core.

Most of the car radiator fans use electronic temperature control to work, so only when the water temperature in the car reaches the required temperature, the fan will start to rotate, if the temperature is too low, the radiator fan will not be able to rotate. Therefore, when the fan does not rotate, the first thing you should do is check whether the water temperature meets the requirements.
