What are the requirements and characteristics of antifreeze?

It depends on the use of the car in **, the south generally uses -25 degrees, and the north uses -40 degrees and -60 degrees. Anti-boiling, anti-corrosion, anti-scale, anti-freezing, anti-rust, anti-engine overheating and other characteristics.

The requirements for antifreeze in cars are not very high, and many cars used to be tap water directly at home.

This specific characteristic is that the color must be consistent, and the general manufacturer will ask to mind the use of the original car's antifreeze is better.

Vehicle antifreeze replacement, especially in northern weather, must be marked below -30°, and the replacement time is best to replace the same color as the original car.

Hello, when the antifreeze used in the vehicle is replaced, it is necessary to replace the original model of the same model, and it is not allowed to change it at will.

Hello, the main role is anti-freezing, another is anti-boiling, and the other is anti-corrosion, which can still protect the engine.

Hello, in the process of use, the engine antifreeze is best to be replaced every two years or 40,000 yuan, and the color should be the same when replacing. If you are not sure, you can check the freezing point of the antifreeze before replacing it.

Generally speaking, most of the boiling points of antifreeze are about minus 30 degrees, so it is recommended to add the same color when adding antifreeze.

Hello car owner, the antifreeze characteristics are anti-rust, high boiling point and low freezing point, only in this way can the engine be protected from corrosion, high temperature resistance without scale, avoid high temperature boiling of the engine, and prevent freezing in cold weather.

Antifreeze is universal, as long as the color is the same, the quality of Bosch or Chefu's antifreeze is better.

Hello, the main thing is the freezing point and boiling point of antifreeze, which is generally used at -25 degrees in the south and around -40 degrees in the north. Antifreeze has the effect of anti-corrosion and high temperature resistance!

Hello, if you want to add or replace a new antifreeze, it is best to go to the local 4S store to replace the original oil

Hello, this pay attention to the freezing point and boiling point, consider the same model and color as the original, and try to choose **accessories.

1. Low freezing point. The minimum freezing point should reach about 150, which can prevent the water tank and cooling.

2. The system pipeline will not be frozen and cracked, and at the same time, it will ensure that the car can be started at any time at low temperature.

3. High boiling point and low volatility. The boiling point allows J to be above 100.

4. Wheel Zen has less scale and good thermal conductivity. It fully plays a role in cooling the engine and parts for the purpose of tam punching.

5. The flash point is high, and it is not easy to catch fire.

6. It does not corrode metal and rubber.

The use of antifreeze is a very good guarantee for the car in winter, because the antifreeze can effectively prevent the engine from freezing due to the rapid change of external weather. When people start the vehicle in winter, they can quickly start the engine and fully solve the problem of people's travel. The advent of antifreeze has greatly facilitated the problem of people starting vehicles in winter.

And now the cost of antifreeze is also very low, and it is not very expensive, so many cars will choose to replace antifreeze when winter comes, the purpose is to ensure that the vehicle can be started smoothly in winter.

When it comes to using antifreeze, I think there are three things to pay attention to, the first is brand assurance. First of all, when buying antifreeze, it is recommended to buy a big brand of antifreeze, not only in terms of quality, but also the use effect is relatively good, compared with other small brands of antifreeze, I think it must be a technical failure, because the entire antifreeze research and development process and technical content are relatively high, many large brand enterprises can be successfully developed by continuously investing money and energy, which is not a small business can be developed casually, so the purchase of antifreeze must buy a big brand, in order to contribute to the safety of automobile engines.

The second point is to use a proprietary type of antifreeze. Because the engine model of each car is different, there is a corresponding antifreeze for each engine, and when you replace the antifreeze for the engine, you should use the same type of antifreeze, so as to have the effect of antifreeze.

Third, we must go to the regular manufacturer to replace the antifreeze, because replacing the antifreeze is a very important thing, and it will even affect the service life of the engine, so when you replace the antifreeze for the car, you must go to the regular manufacturer to replace it, so as to effectively ensure that the antifreeze fully plays its role, and you can't go to the three no manufacturers. This will not only lead to damage to your own car, but also cause irreparable damage to the engine, and even affect the car after winter.

Antifreeze should also be careful not to use too much during use, and should also be replaced in time to protect the vehicle, especially in winter, it must be replaced, and some effective antifreeze should be selected.

If antifreeze is used in winter, it is a very good guarantee for the car. Because of the antifreeze, it can effectively prevent the engine from freezing due to changes in the trajectory of external weather. And he can also solve the problem of people's travel.

Then when choosing antifreeze, you must choose the brand guarantee must choose the best one, so that the effect will be very good. Then each antifreeze has its own model, because the engine model of each car is different, so it also has a corresponding antifreeze for each engine.

To choose the model corresponding to the car, choose some antifreeze with better functions, be sure to use it according to the instructions when using it, and then use it in different seasons, and be sure to pay attention to the temperature when applying antifreeze.

When using, we must pay attention to replacing it in time, especially in winter, it must be used for the vehicle, which can also avoid some problems with the vehicle and avoid the situation that it cannot be driven.

"Antifreeze" is engine coolant, which is an indispensable heat dissipation medium for the normal operation of automobile engines. The main function of antifreeze is to prevent the coolant from freezing and cracking the radiator and freezing the engine block or cover when parking in the cold winter, and when the temperature is high in summer, it can effectively prevent boiling and avoid boiling. Automobile antifreeze has a large effect, which directly affects the performance and service life of the car.

Antifreeze is a substitute for water. Because it is cold in winter, the water freezes at 0 degrees Celsius. Whereas, antifreeze has a low freezing point and does not freeze.

First, the antifreeze does not contain water alkali, and long-term use will not cause water channel blockage; Second, antifreeze contains special additives, which can prevent rust and corrosion and protect the cooling system; In addition, the boiling point of antifreeze can reach 120 degrees Celsius, while the boiling point of water is only 100 degrees Celsius, so adding antifreeze can effectively prevent the pot from boiling. So, it's best to stick to antifreeze all the time, and of course, if the car breaks down outside, there won't be any problem with using water as coolant for a short period of time.

In the process of use, we must control the dosage, and we must store it well, put it in a cool and ventilated place, and pregnant female friends must not touch, and when using antifreeze, do not touch it, do not add water, and be sure to check it regularly, do not open the lid rashly, and do not use different types of antifreeze together.

It is very important to pay attention to controlling the temperature, otherwise it is easy to solidify, and in the process of use, we must ensure that there is no sprinkling outside, it is easy to have some problems, and we must pay attention to replacing it in time when using.

First of all, the antifreeze can not be directly contacted**, especially into the eyes and the human body, and there is an erosive effect, when using it should prevent leakage, do not let the oil invade the antifreeze.

What needs to be paid attention to in the process of use is that it must be used in winter, otherwise the car will be frozen because of the low temperature, and in the process of use, you should also pay attention to the dosage, replace it in time, and be sure to warm the car.

The full name of automotive antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze prevents the coolant from freezing in the cold winter months, causing the radiator to crack and freeze the engine block or cylinder head. Many people think that antifreeze is only used in winter, but we need to correct this myth.

In fact, antifreeze is not only used in winter, but also all year round. It is advisable to go to the new Punchak trunk car service chain store to replace the antifreeze.

Introduction to the functions of antifreeze.

Temperatures are low in winter. When the car is still used at low temperatures, some substances that can reduce the freezing point of water will be added to the engine coolant as antifreeze to ensure that the cooling system will not freeze at low temperatures. The full name of antifreeze is antifreeze coolant, that is, coolant with antifreeze function.

Judge the quality of antifreeze.

There are two main points to evaluate the quality of stuffy antifreeze:

First, the antifreeze effect. Ordinary antifreeze can withstand -40, and high-quality antifreeze should resist about -60, which is an important indicator to judge the quality of antifreeze.

The other is the boiling point of antifreeze. The boiling point of antifreeze should be at least above 108, and its boiling point temperature should increase as its freezing point temperature decreases. The greater the temperature difference, the better the quality of the antifreeze.

Introduction to precautions for the use of antifreeze.

Different brands of antifreeze use different metal corrosion inhibitors, so different brands of antifreeze cannot be mixed. For vehicles that use antifreeze, do not refill tap water directly. Vehicles to which distilled antifreeze should be added.

Do not recharge tap water directly. Distilled or deionized water should be added. If there are no conditions, it is better to add cold boiled water than tap water.

If antifreeze is lost due to leakage, it should be replenished with antifreeze of the same brand. Antifreeze is used all year round. Using tap water in summer is unscientific and the gains outweigh the losses.

If the owner has already replaced antifreeze with tap water in the summer, then thoroughly clean the car radiator in the winter and then add antifreeze. Some antifreeze will have a small amount of flocculent precipitation after one year of storage. This phenomenon is mostly caused by the precipitation of additives, and there is no need to throw it away.

If a large number of particles settle, the antifreeze has deteriorated and can no longer be used.

The role of antifreeze:

1. The antifreeze has the function of antifreeze and has a low freezing point. The freezing point of water is 0, and the freezing point of antifreeze can reach -25 -60. In the cold winter months, it prevents the coolant from freezing and cracking the radiator and freezing the engine block, while also ensuring that the engine can be started at any time.

2. The antifreeze has the function of anti-boiling, and the boiling point of the antifreeze is higher than that of water. Boiling point refers to the temperature at which a liquid boils. At standard atmospheric pressure, the boiling point of water is 100, while the boiling point of antifreeze is higher than 106, which can effectively prevent the "boiling" phenomenon of the engine.

3. Antifreeze has anti-corrosion function. Because the cooling system of the engine includes several metals such as steel, aluminum alloy, cast iron, copper and solder used in the welding of the water tank, the cylinder block and cylinder head are generally made of cast aluminum or cast iron, and the water tank is mainly made of copper and brass, and the antifreeze is in contact with these metals for a long time, so it must be able to protect all these metals, and the use of deionized water and appropriate additives can prevent the emergence of various corrosions.

4. Antifreeze is "oily", which can prevent the dissolution, bulging and aging of non-metallic materials such as rubber and plastics, and the antifreeze of some vehicles has a lubricating effect on the cooling system.

5. Antifreeze can prevent the formation of scale. Scale is caused by the adhesion of insoluble salts or oxide crystals on the inner surface of the cooling system. The main substances that produce scale are calcium sulfate, calcium carbonate, magnesium carbonate, etc., and the high-quality antifreeze is made of distilled water, and added with anti-scale additives, which not only does not produce scale but also has the function of descaling.

When choosing an antifreeze, the following points should generally be followed:

1. Select the freezing point (i.e., freezing point) according to the ambient temperature conditions of the unit. Freezing point is an important indicator of antifreeze, and under normal circumstances, its freezing point should be about 10 times lower than the minimum temperature in winter under local environmental conditions. The antifreeze grade is generally its freezing point value, and the purchase reference value in different regions should be different, the antifreeze with the grade of -25 can be used in the south of the Yangtze River throughout the year, and the water tank coolant with a freezing point value of -15 C can also be used in some areas; The areas north of the Yangtze River, Northeast China and Northwest China should use antifreeze of -35 -50. Note that different manufacturers and different grades of antifreeze cannot be mixed.

2. Choose antifreeze according to the different requirements of the unit engine, such as permanent antifreeze for imported engines, and direct use of antifreeze for domestic engines, which can be replaced with demineralized water in summer.

3. Choose antifreeze with anti-rust, anti-corrosion and descaling ability as much as possible. The engine and its cooling system are made of metal, including copper, iron, aluminum, steel and solder. These metals come into contact with water at high temperatures, and over time, they will be corroded and rusted.

Antifreeze not only does not corrode the engine cooling system, but also has anti-corrosion and rust removal functions.
