What is the reason why the car water tank has been boiled since the antifreeze was changed?

It is caused by the water temperature being too high due to the radiator stopping.

In fact, the high temperature of the engine makes the temperature of the antifreeze rise during the driving of the car, reaching a boiling state, and the overflow will emit white smoke when it hits the high-temperature metal.

Boiling antifreeze may be due to the radiator stopping and causing the water temperature to be too high; The antifreeze does not circulate, the thermostat is not turned on, and the water pump fails to work normally, causing the water circulation pipeline to be blocked, resulting in boiling; It may also be that the antifreeze is insufficient or the quality of the antifreeze is not good, the boiling point is low, and it is easy to boil.

Antifreeze replacement.

Engine antifreeze needs to be replaced every two or three years, but if you choose a better quality antifreeze and the engine cooling system is leak-free, then the replacement time can be extended. The most reliable way to do this is to go to a professional store and test it with an inspection tool, which saves money, saves time and is also very environmentally friendly.

If the test results show that the freezing point of the antifreeze remains below -30, then it does not need to be replaced. Otherwise, it means that the antifreeze needs to be replaced, and all the antifreeze should be cleaned when replaced, and no water or other brands of antifreeze should be added.

When this happens, the owner immediately finds a safe place to park the vehicle, but the owner must never turn off the car immediately. Keep the engine idling so that it continues to dissipate heat, while opening the engine's hood to increase the rate of dissipation.

Note: Do not do the following while the water temperature is boiling:

1. Do not try to continue driving, so as not to cause greater damage to the car.

2. Don't try to open the car's radiator lid immediately, otherwise you are likely to be scalded by the hot liquid spraying out.

3. Do not pour cold water on the engine block and cylinder head, which is very likely to cause the cylinder block to be blown up due to quenching After a period of time, we are checking whether there is water leakage under the car. Be sure to wait until the water thermometer hand has dropped to the appropriate temperature position before turning off the engine.

Wrap the water tank cover with a wet towel, and then slowly open the first channel switch (about 1 4 turns), wait for the water vapor pressure to be effectively released, and then completely open the water tank cover after the release is completed, check the water volume and quality in the water tank, and whether there is any abnormality in the fan belt. If the amount of water is insufficient, you should slowly add water to the vicinity of the highest marking. If the water tank is leaking or the fan belt is loose or broken, call the towing company's ** and wait for the tow truck to rescue.

The reason for the "boiling" of the car water tank is generally due to the insufficient water level and the water tank. Rust, water leakage, etc., that is, these causes cause the tank temperature to reach the boiling point. At this time, the engine will not dissipate heat.

On the other hand, it will lead to too high temperature, and the viscosity of the oil will decrease, which will aggravate the wear of each part.

1. The cooling water in the engine water tank reaches the boiling point, and produces a large amount of water vapor, which will produce a large number of bubbles, and a part of the cooling system is occupied by bubbles, which will make the cylinder wall around the serious water deficit, so that the engine lacks cooling, and will reduce the strength of the piston, piston ring, connecting rod and other components, and even deform, and can not bear the normal load, and at the same time, it will also destroy the normal gap between the parts, so that the normal oil film can not be maintained between the parts, and the engine will pull the cylinder and pull the swag. In other cases, the entire engine can be damaged or even scrapped.

2. Selection of antifreeze: the freezing point of antifreeze is 10 lower than the minimum temperature in winter in the place of residence. The mainstream brand products of antifreeze are basically 40-60 yuan a barrel, with a capacity of 4 liters (the volume of the general car water tank is almost 4L).

The ** of the original concentrated antifreeze may be slightly more expensive, generally about 80 yuan a bottle, and the capacity is about that. When replacing the antifreeze, it is necessary to add it in proportion, and in general, the ratio of antifreeze to water is 1:1 or 1:

A ratio of 2 is sufficient.

3. The replacement cycle and replacement method of antifreeze.

The recommended replacement cycle of the original antifreeze will vary from manufacturer to manufacturer, but the vast majority of them recommend that car owners replace the vehicle antifreeze every 2 years, and some manufacturers show that their original antifreeze replacement cycle is 4 or 5 years. But no matter what, in short, it has to be replaced, which is nothing more than the length of the replacement cycle.

4. When replacing the antifreeze, the first and most important thing is to wait for the vehicle to cool down, and do not replace the antifreeze when the engine is at a high temperature. First, there will be a risk of burns, and secondly, the release of antifreeze during the "hot car" will also affect the cooling of the vehicle.

5. When filling with new antifreeze, you can directly pour about about (depending on the model) of antifreeze into the storage tank, and stop filling after the liquid level height reaches the upper limit max position. At this time, unscrew the drain screw next to the "water pipe", and continue to start filling the antifreeze, see the antifreeze gushing out of the drain screw continuously and without bubbles, and then tighten the drain screw, so far the first time to fill the antifreeze and release the air The work is basically completed.

After starting the vehicle, idle for 3-5 minutes to let the vehicle enter the normal working temperature, and make the new antifreeze can be fully circulated in the waterway in the car, and then turn off the engine, open the reservoir will find that the liquid level height has decreased, then only need to add an appropriate amount of antifreeze to keep the liquid level between max and min.

1. The fan belt is broken, the 2-cylinder mattress is flushed, and 3. The air is not exhausted with antifreeze.

There is no need to worry about the car "boiling".

Teach you how to cope.

Under the "baking" test of hot weather, not only people are too hot to stand, but the car is also so hot that it is "boiling"! Found that the car tank is "boiling", we can do this:

1.If you encounter an alarm of high water temperature while driving, you should slow down in time and stop in a cool place on the side of the road.

2.Keep the engine idle without stalling. At this time, the parts are in an expanded state, and the flameout is easy to cause the soft metal to fall off or even stick to the cylinder.

3.When "boiling", remember not to add water immediately. When the temperature drops, unscrew the water tank with a damp cloth and add antifreeze after the water vapor is slowly discharged.

If there is no antifreeze, you can add cold water for emergency, but replace the antifreeze afterwards to avoid scale in the water tank and affect the heat dissipation performance.

Prevent the car from "boiling".

It's important to check ahead of time.

In the hot summer, it is recommended that the owner remember to check the water tank before going out, and add it in time if the antifreeze is insufficient. Usually, it is also necessary to develop the habit of cleaning the radiator sheet regularly, cleaning the water tank in time, and paying attention to the temperature of the water tank during long-distance driving, so as to avoid the "boiling" of the water tank and delaying the trip.

Boiling the pot is to indicate that the engine is overheating, antifreeze is antifreeze, and cold is generally coolant.

Cause. 1. The water temperature sensor or water temperature gauge is faulty.

Solution: Repair and replace the water temperature sensor.

2. Drive downwind or drive at low speed and high load for a long time in high temperature season.

Solution: Control the travel time and avoid driving under heavy load.

3. The ignition time is too early or too late.

Solution: Ignition at an appropriate time.

Can you change the antifreeze when the water tank of the old car is boiled Hello touch the socks, yes, wait for the temperature to drop, and then add the antifreeze to the water tank. The way to boil the pot is: 1. Park the car in a safe place and let the engine idle for a period of time; 2. After waiting for the temperature to drop, add antifreeze to the water tank.

The method of replacing the antifreeze is: 1. Open the engine compartment cover of the vehicle and find the reservoir of the antifreeze; 2. Open the antifreeze plug under the water tank and drain the old antifreeze; 3. Add new antifreeze and tighten the cap. The role of antifreeze:

1. It has the functions of anti-corrosion and rust removal; 2. The boiling point is high, which can prevent the water tank from boiling; 3. The antifreeze is made of distilled water, which has the effect of descaling.

OK. If not, there will be impurities in the water, which will react with the substances in the antifreeze liquid of the original slag, the light one will reduce the antifreeze effect, and the heavy one will deteriorate the liquid and corrode and damage the water tank.

The full name of the frozen grip hole liquid should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze prevents coolant from freezing and cracking radiators and freezing engine blocks or covers when the coolant freezes when parking in the cold winter.

It may be caused by the radiator stopping and the water temperature being too high.

In fact, the high temperature of the engine makes the temperature of the antifreeze rise and reach a boiling state, and the overflow will emit white smoke when it hits the high-temperature metal.

Boiling antifreeze may be due to the radiator stopping and causing the water temperature to be too high; The antifreeze does not circulate, the thermostat is not turned on, and the water pump fails to work normally, causing the water circulation pipeline to be blocked, resulting in boiling; It may also be that the antifreeze is insufficient or the quality of the antifreeze residue is not good, the boiling point is low, and it is easy to boil.

If the antifreeze is boiled, it is recommended to pull over, let the engine idle for a period of time, let the temperature slowly drop down, check whether the heat dissipation system is running normally, check the amount of antifreeze, if it is caused by insufficient antifreeze, after the engine temperature is reduced, replenish it in time, if there is no antifreeze, you can add a small amount of water as a last resort, and go to the nearest repair shop for repair and replacement.

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.

The following is how to deal with the antifreeze boiling: 1. Pull over and let the engine run slowly for a period of time to let the temperature slowly drop. 2. If the filial piety liquid is caused by the lack of antifreeze in Yuanzhen, it should be replenished in time after the engine temperature is reduced.

3. If there is no antifreeze, you can add a small amount of water as a last resort and go to the nearest repair shop for replacement. The following are the reasons for boiling the antifreeze: 1. The radiator stops running, causing the water temperature to be too high.

2. The antifreeze does not circulate, the thermostat is not opened or the water pump fails to work normally, resulting in the blockage of the water circulation pipeline and the boiling of the pot. 3. Insufficient antifreeze. Insufficient antifreeze is prone to boiling.

4. The quality of antifreeze is not good, the boiling point is low, and it is easy to boil.
