Why is the water temperature high when the car runs at high speed?

Hello, there are many reasons 1. The water level is insufficient. The long water cycle will cause the water to be lost slowly, resulting in a lack of water in the tank, and we do not check and add water in time. This can easily cause the water tank to "boil".

2. The water tank is corroded. If there is dirt in the tank, such as mud, rainwater, etc., it is easy to rust the tank. 3. The water tank is leaking.

A leak in the water tank will block the water circulation and seriously cause the water tank to "boil". 4. The thermostat size cycle conversion is not working properly. 5. The speed of the cooling fan is abnormal, the cooling fan may be damaged or the wire is short-circuited, causing the fan to not work, or the cooling fan speed is very slow.

If my answer is helpful to you, please set it to.

Hello, first, it is caused by too much carbon deposit in the engine or early ignition time. When the engine has too much carbon deposit, the heat cannot be completely dissipated under the condition of high load and high speed, so the water temperature rises; An early ignition time can also cause the engine temperature to rise at high speeds. Second, it is caused by the poor heat dissipation of the water tank.

It is recommended that you check and clean the carbon deposits in the engine system, and pay attention to avoid ultra-high-speed and overload operation during driving. 3. Choose the type of spark plug correctly. Hope it helps.

This situation is mostly caused by poor heat dissipation of the heat dissipation system, and the following parts can be checked:

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 your car's 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.

4. Check whether the grounding of the ground wire near the battery and the engine water temperature sensor is not real, if the ground wire contact is not real, it is easy to cause the water temperature indicated by the water temperature gauge to be high, which is also called false high.

The cooling system of the vehicle has a large cycle and a small cycle, the small cycle is not through the radiator, commonly known as the water tank, the control of the size of the cycle is completed by the thermostat, check the working status of the thermostat, or clean the waterway of the engine block, too much scale affects the heat dissipation, and the front of your water tank should also be cleaned, long-term driving, there are many small insects and debris in the gap of the water tank, which affects the heat dissipation.

Hello! Running high speed is that the engine runs continuously for a long time, the cycle of water temperature circulation is short, the surrounding environment temperature is high, and the overall water temperature remains high, which is normal. FYI.

This must be their own engine is worn, and it is very serious, plus the speed is relatively fast on the highway, if the weather is hot, it will make your water temperature super high.

This can usually happen because the thermostat is malfunctioning and there is some problem with the coolant circulation.

When the engine temperature is low, the coolant circulates and dissipates heat inside the engine, and the heat increases after the load increases, at this time, the coolant will quickly dissipate heat through the heat dissipation tank at the front of the car, and the thermostat is the switch of the large circulation, which is installed in the main water channel, and the wax is encapsulated with wax after reaching a certain temperature, and the thermostat is opened, and the coolant is dissipated through the radiator. When the thermostat opening is not enough, the coolant circulation flow is small, and the heat dissipation is not timely, which will lead to high temperatures. Insufficient opening of the thermostat will also make the temperature difference between the inlet and outlet pipes of the cooling tank larger.

1. First of all, after finding that the water temperature is too high and stopping to the side, it should not be turned off immediately, because there are many reasons for the high water temperature, but there is probably only one fault each time, if all other functions are turned off, the water temperature will be too high, damaging the engine, the accurate approach should be to idle the park, open the hood, turn on the heater, dissipate heat as soon as possible, and pay attention to parking in a cool place. 2. Next, we have to check whether the coolant is sufficient, this situation is likely to be that the owner usually does not care about forgetting to add it in time, and it should be noted that the owner must choose the same brand and model of product when adding coolant, otherwise it may cause chemical reaction due to different components and lead to the failure of antifreeze. 3. Then, we are looking at whether the cooling fan is running normally, and the failure of the cooling fan will cause the heat generated in the car engine to be transferred to the antifreeze at high running speeds and not get timely heat dissipation, resulting in an increase in the temperature of the antifreeze.

If the fan is stuck or the insurance is burned, you can solve it as soon as possible after the power failure, if it is a line problem, it can only be handed over to the professionals of the 4S shop to overhaul. Extended Information:Car Radiator Function:

The function of the cooling system is to dissipate excess and useless heat from the engine, so that the engine can operate at normal temperature at all speeds or driving conditions.

The water tank is the heat exchanger of a water-cooled engine, which is cooled by air convection to maintain the normal operating temperature of the engine. Once the engine cooling water in the water tank boils and vaporizes and expands due to high temperature, and the pressure exceeds the set value, the pressure is discharged from the water tank cover (a), which causes the cooling water to decrease and prevent the cooling system line from bursting.

When driving, you should pay attention to whether the engine cooling water temperature gauge pointer on the dashboard is normal. In addition, if the engine cooling fan fails and the engine cooling water temperature rises or the cooling system pipeline leaks, the cooling water may also be reduced.

This is caused by a malfunction of the thermostat in the cooling system, and the solution to this problem is only necessary to replace the thermostat. The engine of the car is water-cooled, and the water-cooled engine relies on antifreeze to continuously circulate heat in the engine, and the antifreeze has two circulation paths in the engine, one is a large cycle, and the other is a small cycle. When the engine is just started, the antifreeze is circulated in a small way, and the antifreeze will not pass through the heat dissipation tank, which is conducive to the rapid heating of the engine.

After the engine is equipped with the normal operating temperature, the antifreeze will be recycled, and the antifreeze will pass through the cooling water tank to dissipate the heat, so that the engine can be kept within a reasonable operating temperature range.

The part that controls the switching between large and small cycles of antifreeze is the thermostat.

If the thermostat is damaged, the antifreeze may be circulating in large or small cycles.

If the antifreeze is constantly circulating in large quantities, it will not cause the engine to overheat.

If the antifreeze is circulating for a small amount all the time, it can cause the engine to overheat.

If the thermostat is damaged, it needs to be replaced immediately.

The antifreeze also needs to be replaced regularly, and the antifreeze will be used for a long time, and the freezing point will rise and the boiling point will decrease, which will affect the normal operation of the engine.

It is recommended that you regularly change the antifreeze when you use the car, and go to a professional store to find a professional to operate the antifreeze when you change the antifreeze.

Summary. Kiss, give you the precautions for expanding high-speed driving, oh <>

1. Vehicle inspection before driving. Dear, before driving, you should conduct a comprehensive inspection of the vehicle, 2. Adjust the rearview mirror. When the mirrors are in the best position, you can better see the situation behind the vehicle.

3. Check the on-board tools. You can use it when it matters. <>

The water temperature is high at high speeds.

Dear, Shen Hall regrets that I am happy to answer for you! <>

The reason why the water temperature is too high when the car is running at high speed is that the Fuqing antifreeze inside the engine of the vehicle is insufficient, and the cooling system of the vehicle is leaking. <>

The temperature and permeability of the flat road are not high, but as long as the high-speed runs uphill, the water temperature will rise, and it will not reach the red line, and the antifreeze will not be reduced when you drive back to check.

Dear, if this happens to your car, the thermostat of the vehicle is damaged, once the thermostat fails, the water temperature will rise abnormally, and you need to replace the thermostat with a new one in time. You also need to check the circulating water pump, the circulating water pump is damaged, it will not be able to reduce the temperature of the Biminra vehicle, and you also need to replace it with a new one. <>

If the thermostat has just been replaced, can you add the water tank cleaner to wash it?

Kiss, do you mean cleaning the thermostat?

The thermostat is new, I mean can you add a tank cleaner to the tank to clean the inside of the tank.

Dear, you can add tank cleaner to the water tank to clean the inside of the water tank. <>

Dear, you can also clean up the engine's waterway, there will also be carbon deposits. <>

Because my flat road and off-road are normal, as long as the high-speed uphill section will be high, will there be a waterway circulation pipeline blocked.

Dear, your situation in this case the engine waterway is blocked, there is a problem with the water tank, you can first clean the water tank where you do the buried cavity, look at the carbon deposition of your engine, clean it up, and then look at your vehicle situation, if the liquid potato is not improved after operation, you need to go to the repair shop to deal with it. <>

Good. Kiss, give you the expansion of high-speed driving note and shout about the <>

1. Vehicle inspection before driving. Kiss, before driving, you should conduct a comprehensive inspection of the vehicle, 2. Adjust the rearview mirror. When the mirrors are in the best position, you can better see the situation behind the vehicle.

3. Check the on-board tools. Zheng Hongsui, who can be used at a critical time, arrives. <>

Do not take off the thermostat, taking off the thermostat will affect the life of the engine, because the water temperature may be too low, and it will not completely solve the problem.

Your car is an old Civic and has been used for too long, so it is recommended that you check the engine condition to see if the engine may need to be overhauled.

You also need to check that your thermostat, water temperature sensor, fan, electronic fan, water tank, water pump, these parts are all in good condition.

In addition, I would like to remind you that it is best not to add water to the water tank of the car, and you should add antifreeze, spring, summer, autumn and winter, which is very important. If you have added water in the past and it is an old car, it is recommended to find someone to clean the water tank.

There is another thing about the water tank, many people ignore the cleaning between the water tank and the condenser, if it is very dirty, it will also affect your heat dissipation, and the heat dissipation of the water tank and condenser will also affect the heat dissipation.

After checking all these questions, you should be able to solve them. If it is only high-speed water temperature and high-speed running without locking, then it is estimated that there is really a problem with the engine condition, and the engine oil is not messy, and it is not expensive to add some semi-synthetic Mobil.
