Do you need to change antifreeze for new cars? Does antifreeze need to be replaced?

Generally, manufacturers recommend that the antifreeze be replaced in two years, but if there is no flocculent precipitation in the antifreeze tank after inspection, and the color has not deteriorated significantly, it can continue to be used.

But if the ambient temperature is very low, it is advisable to replace it regularly to ensure freeze protection performance.

New cars do not need to replace antifreeze, and there is no problem if there is no shortage of antifreeze within five years, of course, the freezing point of antifreeze needs to be tested every year.

New cars generally do not need to replace antifreeze, and under normal circumstances, antifreeze is generally replaced once every two years, so new cars do not need to be replaced.

Antifreeze DAO liquid, but also according to the environment of the car to make a flexible choice, it is recommended that the owner consult the relevant personnel of the 4S shop in time to avoid it.

There is a problem with the vehicle in winter.

Attached: Precautions for the use of automobile antifreeze:

1. Before adding car antifreeze, you need to check whether there is leakage in the cooling system of the car engine.

When there are no leaks in the engine's cooling system, the owner proceeds to the next step.

2. Before adding new antifreeze, the cooling system of the engine needs to be cleaned to avoid some impurities mixed into it and affected.

Normal use effect.

3. In the process of daily driving, it is necessary to check the antifreeze of the car to check its performance and use, and the general antifreeze.

The validity period is 2 years or 40,000 km.

4. When adding automotive antifreeze, it is not recommended to mix antifreeze from different manufacturers, and antifreeze additives from different manufacturers may not.

In the same way, there may be a decrease in performance or other precipitation after mixing, which will affect the cooling effect of the engine.

5. Check the liquid level of antifreeze in time, it is recommended to check it once a month, and it is necessary to check it when the car is cool, and do not check the hot car.

Check, otherwise the hot water spray is very easy to cause scalding.

Hello: Different vehicle manufacturers will have different replacement cycles for coolant, but most of them recommend that car owners replace the coolant every 2 years or 40,000 kilometers, because the driving situation of each car is different, you can choose to replace it according to the actual use, and check the use of coolant in time. If the coolant is found to be lower than the minimum scale value (the normal value of coolant should be between max and min), it should be added in time, otherwise the cooling performance of the engine will be affected.

Precautions for adding coolant:

1. Coolant can not be mixed: it is best not to mix different types of coolant, so as not to cause chemical reaction, precipitation or bubbles, which will cause damage to the rubber seal, which will cause water leakage at the water seal of the water pump and welds, and cause engine damage in serious cases. However, the current general-purpose coolant solves this problem to a certain extent.

2. The human body should not touch antifreeze: antifreeze and its additives are toxic substances, do not touch them with your hands, and place them in a safe place after use. The unused coolant should not be used again, and the waste coolant should be disposed of in strict accordance with the relevant regulations, otherwise it is easy to cause chemical reactions.

3. Necessary inspection before filling: Before filling coolant, the engine cooling system should be thoroughly inspected, and if there is leakage, it should be repaired in time before adding coolant.

Fourth, it is recommended not to add water to the coolant: if tap water is added to the cooling system, it will affect the normal operation of the cooling system due to freezing in winter, and even cause the freezing and cracking of the engine and water tank.

Extended information: The full name of coolant should be called antifreeze coolant, which is coolant with antifreeze function, and it can be seen from the name that it has two main functions: the first is antifreeze, and the second is cooling.

Many people think that coolant is only used in winter, and obviously this statement is wrong, coolant is not just used in winter, it is used all year round. So whether it's cold or heat, cars can't do without coolant. Proper use of coolant not only protects the engine's cooling system and improves heat dissipation, but also improves engine efficiency and extends its service life.

Hope it helps!

New cars do not need to change antifreeze, the antifreeze when the vehicle leaves the factory, the freezing point is generally about minus 40 degrees, generally even if the car has been driven for two years, the freezing point value of antifreeze loss can rise to about minus 30 degrees.

The new car does not need to change the antifreeze within three years, the original antifreeze is better, the new car does not move anything for three years, and it is enough to change the oil, oil filter, and air filter when it reaches a certain number of kilometers.

In the case of a new car, generally speaking, there is no need to consider replacing the antifreeze, but the antifreeze should also be checked, but if the new car has a long inventory period and the landlord has not replaced it, then it can also be replaced as appropriate.

Antifreeze. It needs to be replaced, and ordinary family cars are generally replaced every two years or 40,000 kilometers. Of course, you can decide to replace it according to the actual use, after all, it is not a problem to walk an extra 10,000 kilometers or extend the service life for an extra year and a half.

However, if the car is used very strongly, it needs to be replaced in advance.

However, it is worth noting that the replacement of the antifreeze coolant has not yet been reached.

Within the time limit, if the antifreeze coolant is found to be lower than the minimum value (the normal capacity of the antifreeze coolant should be between min and max), it should be increased in time, otherwise it will cause heating up and affect the cooling efficiency of the engine.

Generally speaking, antifreeze needs to be replaced every 2 years or so, or after about 40,000 kilometers of driving, the antifreeze needs to be replaced. To replace the antifreeze, you need to choose high-quality, the same brand, the same color of the product, the hot car can not be directly filled with antifreeze, you need to cool down the car before adding, to avoid high temperature burns. The shelf life of antifreeze is generally about 2 years, and the high-quality and long-lasting ones can reach 5 years.

The antifreeze will not extend the shelf life because it is unopened, and if it is stored for a long time, some of the chemical components inside may fail, and the antifreeze will also oxidize and deteriorate after being used for a long time, which needs to be replaced, otherwise it will have a certain degree of impact on the cooling system or engine. Antifreeze can not be mixed, different brands, different colors of antifreeze, the formula composition may be different, if mixed, a variety of chemical components may react, will affect the effectiveness of antifreeze; It is also not possible to replace antifreeze with water, the water is easy to boil, and it will produce large star water vapor, which seriously affects the cooling effect, and the freezing point of the water is high, it is easy to freeze, and the water contains impurities and anion and ion, which will produce scale and cause blockage after a long time.

Today share the car antifreeze replacement cycle.

Of course, the antifreeze for new cars is also new and does not need to be replaced. Usually antifreeze is replaced every two years.

Pacific Automobile Network] The anti-eye tracking jelly of the new car needs to be replaced. Coolant has a shelf life, and most of the coolant has a shelf life of about two years, once the shelf life is exceeded, it means that it needs to be replaced. That is to say, the new car has added coolant to the original car, and it needs to be replaced once after two years of use or about 40,000 kilometers.

Antifreeze, also known as antifreeze coolant, means coolant with antifreeze function. Antifreeze prevents coolant from freezing and cracking radiators and engine blocks or caps when the coolant freezes during a cold winter shutdown.

In addition to antifreeze, antifreeze also has the following advantages:

Anti-corrosion function: 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.

Protective effect of antifreeze:

1. It plays a role in anti-corrosion protection for the components of the cooling system.

2. Prevent scale and avoid reducing the heat dissipation effect of the radiator.

3. Ensure that the engine can work within the normal temperature range.

Therefore, the antifreeze of the engine must have the characteristics of anti-freezing, anti-boiling, anti-corrosion, waterproof and non-foaming, and is not affected by the season and region. Among them, freezing point and boiling point are the basic indicators of antifreeze.

Antifreeze for new cars needs to be replaced. Coolant has an expiration date. Most coolants have a shelf life of about two years. Once the expiration date is exceeded, it means that it needs to be replaced. In other words, after the original car is filled with coolant, the new car needs to be replaced for two years or about 40,000 kilometers.

Antifreeze, also known as antifreeze coolant, refers to coolant with antifreeze function. Antifreeze prevents the coolant from freezing the radiator and freezing the engine block or cylinder head when the cold winter months are stopped.

In addition to antifreeze, antifreeze has the following advantages:

Corrosion protection: The engine and its cooling system are made of metals, including copper, iron, aluminum, steel, and solder. These metals are exposed to water at high temperatures, and will corrode and rust over time. Antifreeze not only does not corrode the engine cooling system, but also has the function of anti-corrosion and rust removal.

Protective effect of antifreeze:

1.It acts as an anti-corrosion factor in protecting the components of the cooling system.

The second is to prevent scaling and avoid reducing the heat dissipation effect of the radiator.

3.Make sure the engine can work within the normal temperature range.

Therefore, the engine antifreeze must have the characteristics of anti-freezing, anti-boiling, anti-corrosion, anti-fouling, and no foaming rock, regardless of the season and region. Among them, freezing point and boiling point are the basic indicators of antifreeze.

Millions of car purchase subsidies.

No, the new car leaves the factory with antifreeze and performs very well.

Precautions for antifreeze for new cars:

1. The lid cannot be opened when the car is hot, because the pressure in the cooling system is very high, and the high-temperature coolant inside will be sprayed out after the lid is opened.

2. When replacing the antifreeze, if the inside of the cooling system of the engine is not cleaned, there will be some scale and other sediments left in it, which will make the antifreeze change significantly in a short period of time. If the color of the antifreeze changes, it is an indication that it has deteriorated. Therefore, before replacing the antifreeze, make sure that the old antifreeze has been thoroughly drained and that the cooling system has been cleaned internally.

3. Do not mix different models. The mixing of different types of engine coolant can cause sediment or bubbles, which can reduce the effectiveness of use. When replacing the coolant, the cooling system should be rinsed with clean water before adding new coolant and water.

The car antifreeze can be replaced by itself, but it cannot be cleaned by changing it by itself. If you replace the antifreeze of the original car and choose the same antifreeze as the original car model, you can replace it yourself. Because there is no added water or no celestial inferior antifreeze, even if it is not cleaned, it does not affect the effect of antifreeze.

1.To replace the antifreeze by yourself, you must store it well and not sprinkle it on the road at will, because the antifreeze of the original car is oily, which is easy to make passing vehicles skid. Moreover, the oily antifreeze seeps into the soil, and all the soil with antifreeze will not grow plants, which is also a kind of pollution to the environment.

2.Change the antifreeze yourself, and test the water temperature after changing. After the engine warms up, the temperature must be maintained at 100 degrees Celsius, because the normal working temperature of the engine is 97 degrees Celsius, the water temperature gauge pointer on the instrument has been in the middle position, and the water tank cooling fan must be able to automatically rotate and stop automatically to be considered a normal return, only the water temperature is normal to travel.

1. Before changing the antifreeze, you must wait 10 minutes after the car is turned off. Antifreeze has a high temperature and burns easily after driving.

2. Comprehensive inspection of vehicles: check whether there are signs of leakage and cracks in the pipeline, and check the five-way water pipe. If this part of the antifreeze leaks, replace the water hose or reconnect as needed.

3. Lift the vehicle with a jack.

4. Unscrew the screws of the bottom shell of the water tank with a wrench, and use the waste basin to undertake the old liquid.

5. Cover the expansion box lid with a thick towel, slowly release it until the air pressure is exhausted, and then remove the box cover completely. Pressurize the water inlet of the expansion tank with a compressed air blowpipe gun or a thick towel to remove antifreeze from the engine block as much as possible.

6. Add softened water and idle for 5 minutes to fully clean the inside of the cooling circulation system.

7. Add new antifreeze to the upper limit of the water level.

8. Idle for 5 minutes, then observe the scale of the antifreeze kettle, and fill it up.
