Is there any way to solve the problem of car boiling?

Changing to a waterless coolant with a high boiling point can solve the situation of the car boiling, but the waterless coolant is good, the boiling point reaches 190 °, it will not open the pot, there is no pressure in the water pipe, it is safe and reliable, and the cost performance is also very high.

The problem of the car cooling system, the thermostat may fail, the principle is that when the weather is cold, in order to ensure that the car heats up quickly, the thermostat is in a closed state, at this time, the cooling water (antifreeze or water) inside the car can only be circulated for a small time, that is, through the internal circulation of the cylinder body, when the weather is hot, the thermostat is automatically opened, and the cooling water is circulated and cooled through the cylinder and the water tank, when the thermostat is broken and cannot be opened, the cooling water can only be circulated for a small time, resulting in a high water temperature (the water tank is boiling). It is also possible that the cooling water circulation is blocked due to excessive scale, causing the car water tank to boil. In addition, the water tank fan does not run due to failure, and the heat dissipation is not good, causing the water tank to boil.

Check the cooling system, this problem should be taken seriously, it is easy to increase the cylinder if the cooling is not good, causing damage to the car engine. The solution, it is possible to replace the thermostat, it is possible that the fan wiring is not in good contact, and it is necessary to clean the water tank.

Car water temperature is always too high, why? The normal working temperature of the water-cooled engine is generally about 80-90 °, and the water will begin to boil when the water temperature exceeds this temperature, commonly known as boiling the pot, and the lid on the radiator will be sprayed out as soon as you open it, which will cause your engine efficiency to decrease, accelerate sluggishly, fuel consumption will increase sharply, and the lubricating oil will deteriorate and gelatinize, and then it will burst tiles.

If the water temperature is high and the fan is not turning, then immediately check your fan system, relays, sensors, motors, etc. If the fan is running normally, check the temperature difference between the upper and lower pipes of your water tank, if the temperature difference between the upper and lower pipes is relatively large, the biggest possibility is that your antifreeze has poor fluidity, or even no flow, and the first problem at this time is the problem of the thermostat.

"Boiling", in automotive terms, refers to the boiling point of the cooling water in the engine tank, which means that the water inside is boiled.

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.

<> under the scorching summer sun, driving for too long, and then encountering traffic jams from time to time, if you are not careful, the car "heat stroke" will occur. There are many reasons why your engine can overheat, and when this happens, try to check the following recommendations:

1.Thermostat Blockage: Thermostats that do not switch on and off properly are usually caused by mechanical failure or incomplete filling of the cooling system. The temperature coefficient of the newer thermostat is different from the original one, which is the cause of failure.

2.Fan problem: The fan motor does not move or the fan clutch is faulty, and it cannot be cooled normally.

3.Coolant leakage: If the pipe of the cooling system is ruptured, the coolant will be lost and the heat dissipation will not operate normally; This situation can be improved by simply changing the new pipe.

4.Radiator cover: If the lid pressure of the radiator is not the same, it will cause the spring to loosen and the lid will not close tightly.

5.Exhaust: The three-way catalytic converter is blocked or the tube is ruptured, causing the exhaust to be blocked, causing the engine to overheat.

6.Water pump: After the long-term use of the water pump is highly worn, the parts are worn out and fall off; The only solution is to replace the pump with a new one.

Fault phenomenon: The water temperature gauge needle quickly points to the 100 position. There was a noticeable drop in engine power. When the cold car starts, the engine water temperature rises rapidly and boils, and then turns normal after the cooling water is replenished.

1. The V-belt of the fan is broken or the fixed fulcrum of the generator is loose and displaced. 2.The main valve of the thermostat falls off.

3.The pump shaft is loose from the impeller. 4.

Serious leakage of cooling water. 5.The cylinder gasket is broken, the water jacket communicates with the cylinder, and the high-pressure gas flows into the waterway.

Fault judgment and elimination, if the engine suddenly overheats in the car, should pay attention to the dynamics of the ammeter, if the engine speed is increased, the ammeter does not indicate charging, and the discharge 3-5a position and "0"If the engine temperature is very high and the radiator temperature is low, it means that the pump shaft and blades are loose, and the cooling water circulation is interrupted. If the temperature difference between the engine and the radiator is not large, the cooling system should be checked for serious water leaks. If the temperature rises rapidly when the car is cold, it starts.

The cooling water boiled, and the main valve of the multi-system thermostat fell off and was stuck in the radiator inlet pipe, which hindered the large circulation of cooling water. Because this fault can make the pressure of the cooling system rise rapidly, when the internal pressure rises to a certain extent, it will suddenly impulse the main valve that is stuck and change its orientation, and suddenly turn on the large circulation water path, at this time, the boiling water will quickly rush through the radiator cover. Burnout of the cylinder gasket can sometimes cause water to overflow and exhaust bubbles from the radiator mouth, giving the illusion of boiling cooling water.

This is mainly due to the ablation of the cylinder head gasket or the crack of the cylinder head and cylinder liner, which makes the high-pressure gas run through the water jacket, so that fierce bubbles emerge.

<> "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 solution to the car boiling: 1. Reduce the speed of the car and drive the car to the side of the road, and don't rush to turn off the engine; 2. Put on gloves, add a multi-folded wet cloth to the lid of the water tank, and unscrew a small slit in the lid of the water tank; 3. After the water vapor is discharged and the pressure of the water tank drops, add cool water or antifreeze. Measures to prevent the car from boiling:

1. The owner should do a good job of seasonal maintenance in a timely manner, and frequently check the heat dissipation system to keep the fans, radiators and other parts sensitive; 2. Don't ignore the cleaning of the surface of the water tank; 3. Pay attention to the water temperature when driving for long distances or for a long time.

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 ignition is turned off at this time, the parts are in a state of expansion, and the gap between the accessories is very small, which will cause some soft metals to fall off after the shutdown, and some will 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.

2. Avoid pouring cold water on the engine. When cooling, avoid pouring cold water on the engine, which may cause the engine block to burst due to sudden cooling. The right thing to do is:

Put on gloves, then add a folded damp cloth to the water tank cover, gently unscrew the water tank cover through a small slit, wait for the water vapor to be discharged slowly, and then add cold water or anti-source freeze after the water tank pressure drops. 3. Water pipe seepage: Due to the water pipe seepage and insufficient cooling water, distilled water or pure water can be added for emergency use, and maintenance can be carried out when it is convenient. Just be careful not to open the lid of the radiator when the car is hot, so as not to be scalded by the water vapor sprayed by the internal pressure.

If there is enough water, check the fan behind the tank. When the water temperature is high, the fan will run even after the heat is turned off. If the fan doesn't move, turn the fan blades first to see if the fan motor is stuck.

It is usually easy to turn. 4. If the water temperature is a little high when you usually drive, you should pay attention to whether there is too much soil, cotton wool or gravel on the surface of the water tank, which will reduce the heat dissipation capacity of the water tank. When washing the car, the best friend Sakura is good to clean up.

For older models, high water temperatures may be caused by limescale deposits in the tank and engine, which need to be cleaned in a specialty store.

The whole water tank is like a boiling teapot going straight out of steam, because the weather temperature is not high, hit ** ask me why do I boil? In fact, 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.

When it comes to the "boiling" of cars, many drivers are no strangers to it and have seen it more or less. But when it comes to what to do after the car is boiled, I believe many people will say that they don't know. In fact, during driving, if the driver finds that the water temperature of the car is very high (to the red line of the water temperature gauge) or the engine emits white smoke, the first thing to do is to pull over immediately and turn on double flashing.

Then look at whether the vehicle is driving at low speed or driving at high speed, because the treatment of "boiling" in these two cases is different.

If it is boiling at low speed, the correct way is to pull over immediately, turn off the engine, open the engine compartment cover to dissipate heat, and then call the 4S shop to wait for rescue.

If the engine is running at high speed before boiling, the correct thing to do is to pull over and let the car engine run at idle for a while, and remember not to turn off the engine immediately. Because before the "boiling", the engine is in a high-speed state, and a large amount of heat generated by the engine has not yet been dissipated, if the ignition is turned off at this time, the cooling water in the radiator will not be able to circulate the work, and the temperature in the engine will soar rapidly. Therefore, in this case, the car should be left idling on the side of the road for a while before turning off, and the engine compartment should also be opened 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.
