What happens when a car boils? What to do!

Car boiling usually refers to the engine of the car (a.k.a. engine, internal combustion engine. According to the different combustion oil and ignition methods, it is divided into diesel engine and gasoline engine) The working temperature reaches a temperature that is too high for the normal working temperature range, which affects the normal operation of the machine and damages the machine. "Excessively high temperature" often refers to higher than 85 degrees Celsius, different models have different standards, the more the temperature exceeds the normal temperature, the greater the damage to the machine.

When the water tank is boiled, we must first analyze whether to open the pot at low speed or at high speed, because the treatment after boiling is different in these two cases. When the low-speed water tank is boiled, that is, the engine is in a low-speed running state before the boiling, you should immediately pull over, turn off the engine, and open the engine compartment cover to facilitate its heat dissipation, and then call the service station to wait for rescue. If the engine is running at high speed before boiling, we should immediately pull over and park the car, unlike low-speed boiling, do not extinguish the engine at this time, but idle the car and let the engine run for a while.

Because the engine was running at high speed before, a large amount of heat generated by the engine has not yet been dissipated, and this waste heat needs to be dissipated by residual cooling water.

When the car is boiled, the engine will be high due to poor heat dissipation, and then the piston and the cylinder block are stuck together.

The engine pulls the cylinder, and the boil occurs as soon as possible to pull over and wait for rescue.

Hello, will damage the engine.

It will stick to the cylinder and cool it with cold water or heat dissipation.

There are many reasons for the car to boil, in addition to the hot weather, the overload of the air conditioner, the failure of the heat dissipation element and the lack of water in the water tank will make the car boil. I have compiled the relevant content, welcome to enjoy and learn from it.

What is the reason for the car tank to boil.

1. Long-term water circulation will cause the slow loss of water, resulting in a lack of water in the water tank.

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

3. When the temperature is too high, you can use your hand to touch the temperature of the upper water pipe and the lower pipe to judge, if the temperature difference between the two water pipes is large, it can be judged that the thermostat size cycle conversion is not working properly.

4. If there is air in the cooling system, it will form air resistance, which will make the cooling water circulate poorly, resulting in high engine temperature.

5. If the vehicle is driving on a dirt road or muddy road for a long time, there will be some dirt adhering to the radiator, which will affect the heat dissipation effect over time and cause the water temperature to be too high.

Precautions for opening the car water megabox.

In summer, it is easy to open the water tank, which means that the refrigerant in the water tank has reached the boiling point, and the boiling is very harmful, and the car hurts people, so it has also attracted widespread attention.

Driving on the hot asphalt road, suddenly glanced at the water temperature gauge near the dashboard, and found that the temperature had reached 100 degrees Celsius. Maintenance experts warn that this move is too reckless. If you have been adding antifreeze, 100 degrees Celsius refers to the source is still within the normal temperature range and has not reached the boiling point, the temperature of the antifreeze is between 85 degrees Celsius and 105 degrees Celsius is considered normal, and its boiling point is 120 degrees Celsius.

If you add water, it is estimated that the pot is about to open, but do not tease and care whether it is antifreeze or water, at this time you can not open the lid of the water tank, because there is water vapor in the tank at this time, the pressure is very high, once the lid is opened, the water vapor will be sprayed out, and the consequences are very serious.

<> "High Temperature Water Tank Cooling Tips.

When the car is moving, white water vapor suddenly appears in the hood, or when the thermometer pointer rises rapidly to the high temperature "h" mark position, it means that the engine temperature is too high. This is usually caused by a lack of water in the tank, a leak, or a tank fan not working. The treatment method is as follows:

Step 1: Find a safe place to park your car immediately, but don't turn off the engine immediately. When the hood is opened, keep idling and continue to dissipate heat to increase the speed of heat dissipation.

Note: If the water temperature is too high or even boiling:

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

2. Do not attempt to open the lid of the water tank, otherwise the hot liquid jet is likely to cause burns.

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

Step 2: After some time, check if there is a water leak under the car.

Step 3: Wrap the water tank lid with a damp towel and slowly turn on the first switch (about 1 4 turns). After the water vapor pressure is released, open the water tank cover completely, check the water volume and quality in the water tank, and check whether there is any abnormality in the fan belt.

If the amount of water is insufficient, slowly add water near the highest marking line.

If the water tank is leaking or the fan belt is loose or broken, you can call the towing company and wait for the tow truck to rescue. If necessary, it is also possible to drive the car to the repair shop at low speed after the engine has completely cooled down. Keep in mind that you can't drive at a normal speed, or you could cause permanent damage to the engine.

How to maintain the water tank in winter.

In general, antifreeze should be replaced after 20,000 kilometers or a year. Never add tap water without antifreeze.

Rust and fouling of the engine water tank are the most common problems. Rust and oxide scale will restrict flow in the antifreeze cooling system, reduce heat dissipation, cause the engine to overheat, or even damage the engine.

Antifreeze oxidation can also form acids that can corrode the metal parts of the tank, causing damage and leakage of the tank. The main way to solve the problem of water tank failure is to conduct routine inspections at ordinary times. It is necessary to regularly check the tank for leaks or corrosion.

Antifreeze must be cleaned, replaced, or added to increase the boiling point and extend the service life. In general, antifreeze should be replaced after 20,000 kilometers or a year. This can increase the boiling point, prevent scaling and corrosion, improve heat dissipation, lubricate the water pump, and avoid and eliminate the damage to the engine caused by instantaneous high temperatures caused by air bubbles.

The treatment method of the car boiling: 1. When the water tank is boiled, we must first analyze whether to open the pot at low speed or at high speed, because the treatment of these two situations is different; 2. When the low-speed water tank is boiled, you should immediately pull over, turn off the engine, open the engine compartment cover to dissipate heat, and then call the service station and wait for rescue; 3. If the engine is running at high speed before boiling, you need to pull over and park the car immediately, at this time, do not turn off the engine, but should idle and let the engine run for a period of time, because the engine is running at high speed before, and the heat generated by the engine has not yet been dissipated, and these residual heat needs to be dissipated, otherwise it will be affected; 4. Generally, it is necessary to go to the repair shop for overhaul when the pot is opened.

When we encounter an alarm of high water temperature, we should first slow down, and then drive the car to the side of the road, do not rush to turn off the engine, because the water temperature is too high, which will cause the temperature of the piston, steel wall, cylinder, crankshaft, etc. to be too high, and the oil will become thinner and lose its lubrication. If the engine is turned off at this time, the parts are in a state of expansion, and the gap between the accessories is very small, which causes some soft metals to fall off after the shutdown, and some even cause the cylinder to stick. Therefore, do not turn off the heat immediately after you find that the pot is boiling, but keep idling for the time being to try to cool down.

Do not pour cold water on the engine when cooling down, as this may cause the engine block to burst due to the sudden cooling. The correct way is: put on gloves, add a multi-folded wet cloth to the water tank cover, gently unscrew the water tank cover with a small regret seam, wait for the water vapor to slowly discharge, and after the water tank pressure drops, add cold water or antifreeze.

Due to the seepage of water pipes and the lack of cooling water, distilled water or purified water can be supplemented for emergency use, and maintenance can be carried out when it is convenient. Just be careful not to open the lid of the water tank when heating the car to avoid being burned by the water vapor sprayed by the strong pressure inside. If there is enough water, look at the fan behind the tank, which should be running even after the ignition is off when the water temperature is high.

If the fan does not move, turn the fan blades first to see if the fan motor is stuck, and you can easily turn it under normal conditions. If there is no problem with the motor, check the fan fuse, which is one of the reasons for many occurrences, especially in the summer when the electricity consumption is high. Thermostat failure is also the cause of high water temperature, once the failure will cut off the cooling water circulation, when the water tank above and below the two thick glue pipes have obvious temperature difference, that is, the thermostat is damaged and faulty, need to be removed and replaced, which is generally handed over to professionals to deal with.

If the water temperature is a little high when driving, you should pay attention to whether there is too much mud, cotton wool or gravel on the surface of the water tank, which will cause the heat dissipation capacity of the water tank to decrease, and it is best to clean it up when washing the car. For older models, the high water temperature may be caused by limescale deposition in the water tank and inside the engine, so you need to go to a professional store to clean it.

Summer is a season that annoys people who have a car and socks, because in the hot summer, the car may suddenly "open the pot", burst or spontaneous combustion, among them, the most common problem encountered by the owner is "open the pot", for this problem, the old driver may have found the trick, the new driver may be experiencing, the following is for the novice to solve the problem of "boiling" the car.

What happens when the pot is boiled.

In fact, the so-called "boiling pot" means that the water in the car's water tank reaches the boiling point. The performance of "boiling the pot" is obvious, clumps of steam will come out under the car cover, and when you open the case cover, you will find that the water in the tank has boiled and even splashed outward. It was as if the car was going to be completely paralyzed, and it was not surprising that the old boss had more opportunities, and the novice would definitely be scared when he met it for the first time.

The biggest connection with "boiling" is the poor work of the engine cooling system, such as the water pump is damaged or the water supply is insufficient, the engine is short of water due to water leakage, the thermostat is not opened, the cooling fan does not rotate or the speed is not enough, the air in the waterway is not exhausted, the water tank is too dirty and the heat dissipation is poor, and the engine knocks.

What to do when you encounter "boiling the pot".

What if the car really "boils"? Don't panic, you can DIY yourself. The steps are simple:

Park the vehicle in a cool place, let the car idle and run, check whether the radiator fan is running normally, turn on the power machine cover to improve the heat dissipation rate, wait for the water temperature to drop, turn off the heat, check whether the coolant level is normal, if it is missing, slowly add the fiber supplement to fill the appropriate coolant.

In this way, the problem of "boiling the pot" is solved.

How to avoid "boiling the pot".

We not only encounter problems and solve problems, but also should prevent them early, how to prevent the car from "boiling"? First of all, check the cooling system frequently, especially to check whether the thermostat is working properly. Check whether the water tank is short of water before leaving the car every day, if there is a shortage of water, it should be filled up in time, and you can also put a bucket of water in the trunk in case of emergency.

When driving for a long distance or for a long time, you should always pay attention to the indication reading of the water temperature gauge, the normal temperature is between 85 and 95, if the water temperature is too high, it is best to stop and rest, and you can turn off the air conditioner when you are stuck in traffic. Secondly, clean the surface of the water tank frequently, because dust and the like adhere to the surface of the water tank, which will seriously affect the heat dissipation of the water tank. And do not use water with high mineral content for a long time, such as mineral water, river water, etc., as a coolant.

This kind of water can easily fill the heat dissipation system with limescale, which will affect the heat dissipation.

The first step is to find a safe place to pull over, let the vehicle idle and do not turn off, because the cooling fan and cooling after the ignition is turned off.

The fluid cycle will stop, which will make the engine hotter;

The second step is to open the hood, increase air circulation, so that the water temperature drops, and then add water to the radiator and cover it, unscrew the first gear, etc.

The internal water vapor is discharged and then opened;

The third step is not to add coolant immediately, the water will be boiled in a closed container will produce a certain pressure, if the water is boiled immediately after the fight.

Open the radiator water port, the internal pressure will make the boiling water spray out, which is likely to cause scalding;

Fourth, check whether there is any leakage in the water tank connection pipeline, and then check whether the coolant is sufficient, if there is no available coolant on the car, you can replace it with mineral water first, but replace it with a new coolant afterwards;

Fifth, in the face of engine overheating, what ordinary people can usually do is to check and add coolant, as for others like water pumps, temperature saving.

If it is caused by a malfunction, it is better to ask for rescue.

"Boiling pot", in automotive terms, refers to the cooling water in the engine tank reaching its boiling point, that is, the water inside is boiled into boiling water. There are many reasons why cars are "boiling". In addition to hot weather, empty overload operation, failure of heat dissipation elements, and lack of water in the water tank will make the car "boil".

Do you know what to do when the vehicle you're driving is "boiling"? How to prevent "boiling"?

What factors cause "boiling"?

1.A long water cycle can lead to slow water loss and a lack of water in the tank. If it is not detected and added in time, it can easily cause the tank to "boil".

2.If there is dirt in the tank, such as dirt and rainwater, it is easy for the tank to rust.

3.When the temperature is too high, you can judge the temperature of the upper and lower water pipes by touching your hands. If the temperature difference between the two water pipes is large, it can be judged that the thermostat size cycle conversion is not working properly.

4.If there is empty air in the cooling system, an air lock will be formed, resulting in poor cooling water circulation and high engine temperatures.

5.If the vehicle is driving on a dirt or muddy road for a long time, there will be some dirt sticking to the radiator, which will affect the heat dissipation effect, and over time it will cause the water temperature to be too high.

What should I do if the car boils in the middle of driving?

1.Immediately park your car in a safe place on a flat road that does not affect traffic, preferably in the shade. Place a safety warning sign 50 meters behind the car. If it is a highway, put it 150m behind the car.

Do not turn off the boiler immediately after boiling, but keep it running at a low idle speed first. If the flame is turned off at this time, the part is in an expanded state and the mating gap is small. After the ignition is turned off, some soft metals will fall off, and some will even stick to the cylinder.

2.Idle the engine and lift the hood to dissipate heat faster. When the temperature drops, add enough water to the tank.

When adding water, pad with a damp towel. First, unscrew the water cap of the radiator, let out the water vapor, and then open it all.

Do not add water immediately when boiling, as the water in the radiator will have a certain pressure after boiling. If you open the inlet of the radiator immediately, hot water will spray out, which can easily cause facial burns.

In addition, when the engine temperature is too high, avoid pouring cold water on the engine, which can cause the engine block to burst due to sudden cooling, causing irreversible consequences.

How to prevent a car from boiling? Fight.

1.Whether it's summer or not, daily maintenance is essential. You can also check if the water tank is low on water before driving. If you find that there is a lack of water, you should fill it up in time and pay attention to some small details in the car.

2.It is best to clean the radiator regularly, which will improve the heat dissipation of the engine. Take a break while driving. When resting, try to choose a cool place and open the hood for ventilation and heat dissipation.

3.The dust and cotton wool on the surface of the water tank will also affect the heat dissipation of the water tank, so it should be cleaned as much as possible.

4.Remember to pay attention to the water temperature when driving for long or long periods of time. The maximum requirement should not exceed 95. Once exceeded, the owner will be alert.
