    The situation you are talking about is due to the high temperature of the engine. When white water vapor suddenly emerges from the hood while the car is driving, or the water thermometer needle rises rapidly to the high temperature "H" mark, it means that the engine temperature is too high. This is usually caused by a lack of coolant in the engine, a leak, or a fan not running.

    The car water tank is prone to some minor faults, such as insufficient water level, rust of the water tank, water leakage, etc., which will directly cause "boiling". In this case, you need to pay attention to the following matters:

    First: Find a safe place to park immediately, but never turn off the engine immediately. Keep the engine idling to continue dissipating heat, while opening the hood to increase the rate of dissipation.

    Note that in case the water temperature is too high or even boiling:

    1. Do not try to continue driving, so as not to cause major accidents.

    2. Do not try to open the lid of the water tank, otherwise it is very likely that hot liquid will spray out and cause scalding.

    3. Do not pour cold water on the engine block and cylinder head, which is likely to cause the cylinder block to burst due to quenching.

    Second: After some time, check for water leaks under the car.

    Third: Wait until the water thermometer pointer is lowered to the appropriate temperature position, then turn off the engine.

    Fourth: Wrap the lid of the water tank with a wet towel, slowly open the first switch, and after the steam pressure is released, then completely open the lid of the water tank, check the water volume and quality in the water tank, and whether the fan belt is abnormal. If the amount of water is insufficient, water should be added slowly (which can be temporarily replaced by ordinary purified water) near the highest marking.

    Note: If the water tank is leaking or the fan belt is loose or broken, you can call the towing company ** and wait for the trailer rescue. If necessary, you can also wait for the engine to cool down completely, and then drive the car to the service shop for maintenance at low speed.

    Remember, you can't drive at normal speed, as there is a high risk of permanent damage to the engine.

    This phenomenon is normal.

    The working principle of the engine cooling system is as follows: the excess heat in the cylinder body is brought to the radiator outside the engine by the circulating coolant, and then the heat is discharged into the atmosphere by the cooling fan.

    The circulation of coolant is realized by using the crankshaft to drive the water pump, the water pump stops working after the flameout, and the coolant is not circulating, although the electric fan is still rotating, but the temperature of thousands of combustion chambers before the flameout will still be transmitted to the coolant and the cylinder block in the cylinder body. The water temperature sensor is mounted on the cylinder block, so the water temperature will rise by a few degrees after the ignition is turned off.

    Water tank function:

    The water tank plays an important role in the cooling and heat dissipation of the car. In the summer of continuous high temperature, the car water tank is especially prone to some small faults, insufficient water level, water tank rust, water leakage, etc. will directly cause "boiling", that is, the temperature of the water tank reaches the boiling point.

    At this time, the engine heat dissipation is poor, the temperature is too high, the expansion of parts will reduce the gap between the parts, on the other hand, the temperature is too high, the viscosity of the oil is reduced, in this case, the wear of each part is aggravated. If not treated immediately, the engine is likely to burn out and cause serious damage.

    The engine fault light is on and goes off after starting, which is normal. When the key is opened normally, the engine fault lamp, oil lamp, and battery lamp are all on, and they are all turned off after starting the car, and the instrument is not lit when the car is moving. There are too many possible reasons for the engine failure light to turn on, and it is roughly divided into the following three categories:

    1. False failure. Report the fault**, but the work is normal, it may be that a certain operation is beyond the control of the computer, and the fault of the computer feedback can be eliminated first, and then see if the fault code is still jumped. 2. Minor faults.

    There is no particularly obvious fault in the engine, according to the computer detection information and further inspection, it is found that there is really some kind of fault, which does not affect normal driving or has little impact, and needs to be found and solved in time. For example, the inlet pressure sensor is faulty, etc. 3. Major failures.

    This stool type fault can be felt by the naked eye and driving feeling, and seriously affects the normal operation of the engine, and needs to be repaired immediately. For example, the engine is obviously underpowered, and it is likely that it is an oxygen sensor.

    and so on. After the car is energized, it is time to turn the key to the first gear.

    Or after tapping the one-button start button, have you ever noticed that the engine fault light is on? The engine fault light is a faucet-like fault light on the dashboard. Then, we continue to turn the key, or press the start button again, and after the engine starts normally, the engine fault light goes out.

    What are the reasons for the engine failure light to come on, and can we continue to drive the vehicle after it is on? Next, the little car dad and everyone will talk about those questions about the engine failure light.

    First of all, this engine fault light is not only lit when the engine fails, but includes the entire power system.

    Except for a few with a separate indicator light, all other abnormal conditions of the power system will make the engine fault light on. For example, the abnormality of the oxygen sensor, the abnormality of the exhaust system, the abnormality of the fuel system, the abnormality of the air intake system, and even the abnormality of the anti-theft system are all prompted by the engine fault light is lit.

    So, let's not go to the old driver to ask, this engine fault light is on, is there a problem? The old driver is also unable to judge that the vehicle is specifically faulty just by the engine fault light, because there are indeed many obstacles in the balance. After the engine fault light is on, it needs to be professionally inspected and the specific fault location or abnormal cause of the vehicle can be determined by reading the specific fault information prompt of the driving computer.

    This is a self-check when starting the vehicle.

    The engine fault light is to detect whether the exhaust emissions are normal through the sensor, when the standard is exceeded, it will be an alarm of the engine warning light, in most cases, after the light is on, it will disappear after a while, then it means that he has no big problem, don't worry too much.

    It is likely that after the car is started, some problems caused by poor atomization in the cylinders of the fuel engine cause the engine to alarm. Then you don't have to worry about it, when the temperature comes up, the warning light will naturally go out.

    When introducing fault diagnosis to the electronic control system, don't forget to perform a basic inspection first. For example, before attempting to diagnose a failure in the ECU-controlled fuel injection system, it is important to ensure that the intake lines are leak-free, the valve is on time, and the ignition is on time.

    If these undesirable phenomena exist, the engine's anti-load alternating ability is poor, and it may stall in the case of sudden changes in working conditions, such as accelerating and braking, turning on the air conditioner and shifting the gear.

    1. It is difficult to diagnose the intermittent faults of some cars, unless the fault appears when the car is inspected.

    2. When checking for irregular idle flameout faults, sometimes it is necessary to change the spark plug.

    3. When it is suspected that the air flow meter is bad (such as the air flow meter is too dirty; When the solder joints of the internal circuit connection fall off, the contact is poor, etc.), the oscilloscope can be used to check the air flow meter signal voltage waveform. While the engine is running steadily, gently tap the air flow meter housing with a screw screw handle and observe the oscilloscope. If the waveform changes significantly or the engine stalls, replace the air flow gauge.

    Some air flow meters have loose internal connections, which can cause a sudden change in the voltage signal, which can lead to flameout. This test starts with a vibration method to make sure that the harness joints are in good contact.

    80% of the reasons for this situation are because the generator regulator of the car is broken, resulting in the output voltage being too high The dashboard self-protection restarts, it is recommended to check the car as follows:

    1. Check whether there is a place for the wire end of the dashboard, if the wire end is damaged and there is a place for the iron, this situation will occur.

    2. The contact of the generator joint is poor, check the connector of the generator, there is a plug with three wires on it, and dial the reed after unplugging.

    3. The generator regulator has a mountain problem, try another one.

    4. Try the generator control valve instead.

    1. One possibility is the problem of the car engine or oil circuit, but for the new car, the problem of the engine itself is less likely, and most of the reasons are the problem of the oil circuit.

    2. For old models, the reason for the stalling is not only the lack of driving skills, but also the stalling caused by the use of substandard oil to make the engine dry and collect carbon.

    3. It may be that the "intermittent idle stall" is caused by the engine speed sensor being too dirty, and the idle motor is stuck and the "no idling" is caused. The engine idle motor is stuck; The wire sheath of the idle motor is somewhat worn out; The idle air hole is too dirty; There is a problem with the engine throttle position sensor; There is a problem with the camshaft position sensor or the crankshaft position sensor; The engine speed sensor is faulty or too dirty; There is a problem with the idle control program in the engine's electronic control unit, and so on.

    4. As soon as the engine enters the idle operation, it will turn off, which is called "no idling", and the reasons for this failure are generally: the engine idle motor or the line of the idle motor is not delayed and damaged; Leakage of the vacuum tube of the brake vacuum booster; Broken membrane of the brake vacuum booster; air leakage in the intake manifold; There is a problem with the idle control module in the engine electronic control unit (ECU).

    Summary. Hello, if there is an abnormality in the vehicle after the car water temperature meter is on, it is best to stop and check it immediately to avoid damage caused by engine overheating. The situation you described seems to be related to an overheating engine.

    When the engine overheats, there may be a fault in the cooling system, which could be a problem with components such as the water pump, radiator, water tank, cooling fan, etc., or it could be a lack of coolant or a bubble in the cooling system. In your case, it is advisable to check that the level of the cooling system is sufficient, whether there are any leaks or leaks; Check whether the radiator, water tank, water pump and other components are operating normally; Check if the fan is working properly, etc. If you are not familiar with vehicle repair, it is recommended to send your vehicle to a professional car repair center for inspection and repair to avoid more serious consequences.

    After the car water temperature gauge is on, the car stops on the side of the road, turns off the engine, opens the hood, and starts again after a while, what is going on, what should I do?

    Hello, if there is an abnormality in the vehicle after the car water temperature meter is on, it is best to stop and check it immediately to avoid damage caused by engine overheating. The situation you described seems to be related to an overheating engine. When the engine is overheated, there may be a fault in the cooling system, which may be a problem with components such as water pumps, radiators, water tanks, cooling fans, etc., or it may be a lack of coolant or bubbles in the cooling system.

    In your case, it is advisable to check whether the liquid level of the cooling system is sufficient, whether there is any leakage or leakage; Check whether the radiator, water tank, water pump and other components are operating normally; Check if the fan is working properly. If you are not familiar with vehicle repair, it is recommended to send your vehicle to a professional car repair center for inspection and repair to avoid more serious consequences.

    Go to the repair point to check if the coolant is still there.

    If the engine water temperature is too high and the coolant level is still within the specified range, then the problem may arise in other parts of the cooling system. It may be that the cooling effect is not good due to the lack of fan operation of the radiator or the blockage of the radiator. In this case, it is advisable to re-inspect other parts of the cooling system, which may require detailed inspection and troubleshooting to find the problem.

    It is recommended that you leave your vehicle at the repair point for a more thorough inspection by a professional technician. During this time, please do not continue to drive the vehicle to avoid more serious problems.

    However, when I went to the repair shop, I found no problems.

    Dear, if there is a similar situation after inspection, it proves that the inspection is not in place and there are omissions.

    Will the dial be out of order?

    You can ask the maintenance master to clear the fault for you.

    And then there's the sign that appears and then restarts and it's gone.

    If the vehicle's water temperature is too high, the temperature warning light on the dashboard will illuminate. When you don't see the warning light coming on after restarting the vehicle, it may be because after the engine restarts, the temperature drops and returns to the normal range. However, this does not mean that the problem has gone away.

    If you notice that the vehicle's temperature dashboard is repeatedly showing similar conditions, it is advisable to check and repair the cooling system in time to avoid more serious problems caused by engine overheating.
