The car was very hot after driving a few kilometers, and I found out what was going on when the fan

Hello, the heat generated during the car is already very large, and the heat dissipation is slow, it is recommended to check whether the fan is running normally, if it is running normally, there is no problem.

Hello, in this case, check whether the water temperature is high, the electronic fan can check whether the fuse is blowing, or you go to the repair shop to check it.

Hello, this is normal if you drive a few kilometers and the car is very hot, the fan is not turned because the water temperature of the car has not yet arrived, as long as the engine does not have a high temperature alarm.

Hello, in this case, it is possible that the engine is running and then generating a very high temperature, as long as the water temperature is not alarmed, it is generally fine.

Hello, the original temperature of the engine is relatively high, as long as his water temperature does not alarm, there is no problem.

First check whether the fan burns the fuse to replace the fuse, check the antifreeze, and add antifreeze in time if it is missing.

Idling in place will be very hot for a while, let alone driving a few kilometers, the car is no problem if there is no high temperature alarm, the fan is working according to the instructions of the temperature sensor, it will not run all the time, and it will only turn on when it reaches a certain temperature.

Hello, this is normal, the engine operation will produce a very high temperature, as long as the water temperature does not alarm, then it is no problem.

Is the drive belt broken? Is the fan stuck? Look it up, it's intuitive.

Hello, you can see if there is less antifreeze, or if the sensor is faulty. It is recommended to go to SSSS to check it out.

The entry of this fan, this depends on the water temperature of the motor vehicle, but there is a judgment of the driving computer, generally speaking, the fan will start to rotate when your temperature reaches a certain temperature.

It is normal for the temperature to be high when the engine is working, and the fan is not always rotating, as long as it does not alarm, it is generally fine.

As long as the water temperature of the vehicle does not alarm, there is no problem, and the engine works to generate a lot of heat.

There are a variety of problems that can arise in the car while driving, and drivers need to be cautious. For example, the cooling fan does not rotate, which is a more serious problem, but some drivers take it lightly. One of the cooling fans in the car is not rotating, can I continue driving?

You'll know after reading it.

The cooling fan does not turn around, but it should not continue to drive

One of the cooling fans in the car does not rotate and can no longer continue to drive, because in this case, continuing to drive is likely to cause the problem of overheating the engine temperature, and it may also cause the engine to pull the cylinder when it is strictly imitated.

You must know that after the engine is pulled, it requires a high maintenance fee, which is a little bit more than worth the loss, so if you find that the cooling fan in the car does not turn, you should go to the 4S shop or a nearby maintenance shop for inspection and repair in time.

How car cooling fans work

Now the car engine.

Most rely on coolant.

For heat dissipation, the coolant usually has two different circulation paths in the car engine, one is often referred to as the big cycle.

The other is a small loop.

In the process of engine starting, the coolant will instantly enter the small circulation, at this time the coolant will not dissipate the water tank, can not achieve the effect of heat dissipation, the purpose of this setting is also to help the engine heat up. After the engine starts, the coolant gradually enters the large circulation, at which point it can pass through the cooling water tank and use the cooling fan to achieve the effect of heat dissipation, so that the coolant can help the engine to work in the right temperature range. The cooling fan is an important component of cooling the coolant, and if the fan doesn't rotate, the engine temperature may skyrocket, and it is very likely that the cylinder will be pulled if you continue to drive.

All in all, one of the cooling fans in the car does not rotate, and it is not allowed to continue driving, because this may cause serious damage to the car, and it cannot be blindly moved forward, and it should be repaired and dealt with in a 4S shop in time.

I think of course you can, because a cooling fan, although less efficient, is enough to keep the car moving.

It should be okay, the cooling fan will not affect the normal use of the car engine, it is best to check it, and replace it if it is broken.

No, this is risky, and the temperature in the car can be too high and cause an accident.

Summary. Hello, I am your exclusive service technician, attentive, attentive and careful to help you solve the problem of using the car, the car water temperature is high, the cooling fan does not turn, but after the air conditioner is turned on, the cooling fan runs normally, in this case, it is necessary to consider whether the water temperature control system circuit of the engine has an open circuit and a short circuit to be connected. Although he shares the air conditioning and engine water temperature dissipation, its control wiring is independent.

The normal operation of the air conditioning cooling fan means that the fan itself is not faulty, and it is important to consider whether there is a fault in the control circuit of the engine water temperature cooling system.

Summary] Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

The normal operation of the air conditioning cooling fan means that the fan itself is not faulty, and it is important to consider whether there is a fault in the control circuit of the engine water temperature cooling system.

The car fan keeps turning and the water temperature is not high, which may be caused by turning on the empty switch, or it may be caused by damage to the water temperature sensor. If the water temperature sensor is damaged, it needs to be replaced with a new one. If the fan is turned on empty, it is normal.

The condenser of the car was empty in front of the water tank. When turned on, the fan needs to dissipate heat from the condenser. Of course, the fan will work.

Car air switch is a crucial comfort configuration in the car, car air switch can be used for cooling and heating. When the car is air-cooled, the compressor clutch will be engaged, and the engine will drive the compressor to run.

When the compressor is running, it can continuously compress the refrigerant and deliver the refrigerant to the evaporation tank. The refrigerant expands and absorbs heat in the evaporation chamber, allowing the refrigerant to cool the evaporation chamber. The cooling evaporation box can cool the air blown out by the blower, so that the empty air outlet of the car can blow out cold air.

Summary. Hello dear, it is a pleasure to serve you Dear, there are two factors that induce the start of the electronic fan, one is the engine water temperature, and the other is the air conditioning refrigerant pressure. The working principle is:

The engine water temperature sensor transmits the water temperature signal to the engine control unit in real time, but when the engine water temperature is higher than a certain limit, the transmission signal controls the electronic fan to start. The above is the water temperature, the air conditioner refrigerant control form is the same as the water temperature, and the two do not interfere with each other, if any of the conditions are met, the electronic fan will be activated.

You play Liang well, I have been a car for more than ten years, and I am happy to serve you. I have been engaged in the automobile-related industry for more than 10 years, and I have sufficient professional knowledge, so please feel free to ask questions. I'll hand you over your questions, so please wait a moment.

The car didn't drive long after the cooling fan began to dissipate heat.

What is the reason.

What is the reason.

Hello, I am happy to serve you Hail, there are two factors that induce the start of the electronic fan, one is the engine water temperature, and the other is the air conditioning refrigerant pressure. The working principle is: the engine water temperature sensor transmits the water temperature signal to the engine control unit in real time, but when the engine water temperature is higher than a certain limit value, the transmission signal controls the electronic fan to start.

The above is the water temperature, the air conditioner refrigerant control form is the same as the water temperature, and the two do not interfere with each other, and the rolling ridge will activate when any of the conditions are met.

Whether the car cooling fan starts to rotate depends on the coolant temperature and has nothing to do with time. When the coolant temperature reaches 98, the tank fan will automatically turn on. The car water tank fan is automatically turned on by Yupei, which cannot be controlled manually, and will not be activated at low temperatures, and the medium and high temperatures are divided into two speed gears.

Generally, 95 automatically turns on the mid-range, and 105 automatically turns on the high-end.

So this is a normal situation, oh dear, please don't worry

Does it have anything to do with coolant?

Does it have anything to do with coolant?

That's right, it has to do with coolant.

I didn't have this before, but I changed the coolant a few days ago.

If this is the case, it is because there is gas in the coolant that is not discharged when the coolant is changed, causing the coolant to not circulate.

Is it serious. It's just that this happens during this time, and it slowly normalizes with the consumption of coolant

If this is the case, it will not affect the coolant to be reduced, so add coolant.

If this is the case, it will not affect the coolant to be reduced, so add coolant.

No, it doesn't matter what coolant you have, there's not much air

If you find that the water tank fan is rotating after just turning off the engine, you can wait for a while. Because the water temperature in the water tank drops slowly, the water temperature has not dropped when the fire is just turned off, and the cooling fan will still work for a while before stopping. If the car has been completely cooled and still rotates, it may be that the cooling fan assembly or the wiring of the cooling fan is faulty.

If you find that the fan is rotating after just turning off the engine, it is recommended not to panic at this time, and you can wait for a while. Because the water temperature in the water tank drops slowly, the water temperature has not dropped when the ignition is just turned off, and the cooling fan will still work for a while before stopping.

However, if the car has been completely cooled down, and the fan still does not stop or keeps rotating, it may be that the assembly of the cooling fan or the wiring of the cooling fan is faulty or the water temperature is too high.

Automobile water tank: also known as radiator, is the main chain part of the automobile cooling system; The function is to dissipate heat, the cooling water absorbs heat in the water jacket, dissipates the heat after flowing to the radiator, and then returns to the water jacket to circulate to achieve temperature regulation. It is an integral part of the engine of the car.

Working principle: The water tank is an important part of the water-cooled engine, as an important component of the water-cooled engine heat dissipation circuit, it can absorb the heat of the cylinder block and prevent the engine from overheating due to the large specific heat capacity of the water, and the temperature rises not very much after absorbing the heat of the cylinder block, so the heat of the engine passes through the liquid circuit of cooling water, and uses water as a heat carrier to conduct heat, and then dissipates heat in a convection mode through a large area of heat sink to maintain the appropriate working temperature of the engine.

When the water temperature of the engine is high, the water pump pumps the water repeatedly to reduce the temperature of the engine. The high-temperature water enters the water tank through air cooling and circulates to the engine cylinder wall) to achieve the purpose of protecting the engine, if the water temperature is too low in winter, the water circulation will be stopped at this time to avoid the engine temperature is too low.

If you find that the fan has just started after turning off the fire, it is recommended not to panic at this time and wait a little longer. Because the water temperature in the tank drops slowly, the water temperature has not dropped when it is just turned off. At this point, the cooling fan will still work for a while and then stop.

However, if the car has been completely cooled and the fan still won't stop or continue to run, it may be that there is a problem with the components of the cooling fan or the circuitry of the cooling fan, or the water temperature is too high. It is recommended to go to the store and ask the master to check the fault.

Automobile water tank: also known as radiator, is the main component of the automobile cooling system; The function is heat dissipation. The cold side accompanies the water to absorb the heat in the water jacket.

After flowing to the radiator, the heat dissipates and then returns to the water jacket to circulate to adjust the temperature. It is an integral part of a car's engine.

Working principle: The water tank is an important part of the water-cooled engine, as an important part of the water-cooled engine heat dissipation circuit, it can absorb the heat of the cylinder block and prevent the engine from overheating. Due to the large specific heat capacity of water, the temperature of the engine does not rise much after absorbing the heat of the cylinder block, so the heat of the engine passes through the liquid circuit of the cooling water, conducts heat with water as the heat carrier, and then dissipates heat through the convection of large area of fins to maintain the appropriate working temperature of the engine.

When the engine water temperature is high, the water pump repeatedly pumps water to reduce the engine temperature. (The tank is a hollow copper tube.) The high-temperature water enters the tank, and the air is cooled and circulated to the engine cylinder wall) to protect the engine.

If the water temperature is too low in winter, the water cycle will be stopped at this time to avoid the engine temperature being too low.
