How long is it reasonable to change car antifreeze? What does antifreeze do?

Antifreeze replacement. This is a need to see. The antifreeze manufacturer of the original car is required.

Some car companies may use some better antifreeze for the antifreeze installed by the factory, and it is generally replaced at 100,000 kilometers. There are also some ordinary ones. As for the normal one, I would recommend replacing it in two years.

Auto maintenance technicians, professionals, interpret professional problems! Pay attention, don't get lost, your own vehicle problems, you can consult me privately! Must be replaced, but not regularly!

Antifreeze is also not like what Tan said on the Internet, it never needs to be changed.

We all know that every time the maintenance, oil and machine filter are necessary to change the items, and the rest such as spark plugs, transmission oil and cooling water are also unknown, I feel that it is a long time and the time has not been changed, plus in the patient recommendation of the service consultant for the antifreeze Q&A, really wrote a lot, now it seems that for the knowledge of antifreeze, there are still some misunderstandings! Regarding the popular science of antifreeze, I won't do it, and those who want to know can check it on the Internet.

It is recommended to replace it in two years or 40,000 kilometers, whichever comes first. The replacement cycle is not certain, and the actual replacement cycle is still based on our car environment and habits. If the number of kilometers is a little higher, it doesn't matter if the replacement cycle is extended appropriately.

What we call antifreeze is actually coolant, and antifreeze is just one of its functions. In addition to antifreeze, there are other functions, such as anti-rust, anti-corrosion, lubrication, high boiling point, etc., all of which are the functions of coolant. How often should antifreeze be changed?

Most cars need to be replaced in 3 years or 60,000 kilometers, whichever comes first.

There is no specific replacement cycle for car antifreeze, and there is no fixed mileage, generally speaking, there are great differences in the replacement cycle and mileage of the original coolant of different car brands, some tens of thousands of kilometers, and some can reach more than a dozen, depending on their own car. The car needs to be replaced once a year if the car runs continuously for a long time, and it is necessary to see if the car is lacking often, and if so, you can add some points appropriately. If you don't run often, change the antifreeze every two years.

Generally, it is changed every two years or about 30,000 kilometers, and the antifreeze does not need to be changed frequently. Antifreeze can play a role in lubrication, protect parts from corrosion, antifreeze has a very high boiling point, and can also play a role in descaling.

I change it every two or three months. In order to prevent the car from freezing in cold weather and not being able to drive the car, antifreeze has a good effect in winter.

As long as the freezing point of the antifreeze is not low, it can be said that it does not need to be replaced permanently, and the main role of the antifreeze is to prevent the cooling water in the winter pipeline from icing, expanding and cracking the radiator and freezing the engine cylinder block. It also protects cooling parts from corrosion and is an indispensable fluid for automobile engines.

Most family cars are replaced every two years or 40,000 kilometers.

Of course, this is only a reference replacement cycle, which can be replaced according to the actual use, because it is not a big problem to go one or two thousand kilometers more or extend the use cycle for about one and a half years. If the car is used intensively, it can be replaced in advance.

However, if the antifreeze coolant is found to be less than the minimum scale value (the normal capacity of the antifreeze coolant should be between min and max), it should be increased in time, otherwise the cooling efficiency of the engine will be affected.

If the antifreeze is different from the last time you added it, then you must pay attention to clean up the last time and replace it.

Ordinary models can be replaced in about two years, and luxury models can even be replaced for up to ten years, antifreeze as the name suggests is used for antifreeze, so the role of antifreeze is to prevent the parts in the pipeline from being frozen in winter.

Car antifreeze is used in every car, it can protect our car from frostbite, whether it is for the exterior or interior of the car, it is very effective. However, car antifreeze has a shelf life, and it needs to be replaced in time after the time, if the replacement is not timely, the car may be frozen and damaged, and the loss will be very large.

The general shelf life of car antifreeze is two years, after which it needs to be replaced in a timely manner. There are also some people who choose to use water to prolong the use of antifreeze, but this method is very undesirable. Because the antifreeze has been used for two years, if you add water at this time, the impurities in the water will affect the antifreeze, and it is easy to have serious quality problems.

There are also some brands of antifreeze that have a shelf life of 4 to 5 years, but I personally feel that it is better not to use such long-term antifreeze. Because the air itself contains impurities, after 4 to 5 years, the concentration of antifreeze will be very large, and there are many impurities in it, which is very inconvenient to use, and it is easy to have some big problems, and then the gains outweigh the losses.

So the advice to you is to change the antifreeze every two years. It is best not to use antifreeze with a long shelf life, and it is better to have a short replacement cycle. Don't keep dragging it out because you are reluctant to buy antifreeze, and eventually cause irreparable consequences.

The time to change the antifreeze is determined according to the time of using the car, and the time to change the antifreeze when different people use the car is different.

kind. Most family cars are replaced every two years, perhaps 40,000 kilometers. Of course, this is just a reference for the replacement week.

Period, it can be replaced according to the actual use situation, because of the extra 10 million kilometers or the use cycle extends for more than a year and a half.

Right, it's not a big problem. If the car is strong, it can be replaced early.

The main function of car antifreeze is to control the temperature of the car engine, and to ensure the normal operation of the car in winter.

Running. Antifreeze has excellent properties such as anti-freezing in winter, anti-boiling in summer, waterproof scale and anti-corrosion throughout the year. At present, more than 95% at home and abroad.

Compared with tap water, the most significant feature of ethylene glycol is that it is antifreeze, while water cannot be antifreeze.

Secondly, ethylene glycol has a high boiling point, low volatility, moderate viscosity and small change with temperature, and good thermal stability. Hence, the ethylene glycol type.

Antifreeze is an ideal coolant.

Like the antifreeze of the car, it generally needs to be replaced every two years or 40,000 kilometers, but in the later use, the antifreeze effect of the antifreeze can be tested by the freezing point tester, and if the antifreeze effect is not a problem, the replacement cycle can be extended.

Ask how to test the freezing point.

Thank you for your question.

Generally, the chemical composition inside the antifreeze will fail after 3 years.

Although the freezing point is still very low, the chemical composition of the internal anti-corrosion and anti-oxidation has become low, so in order to prevent the antifreeze from forming scale, it can be replaced in 3 years. Thank you for adopting.

The replacement time is generally one to two years.

The full name of antifreeze 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.

Many people think that antifreeze is only used in winter, but in fact, antifreeze is used all year round.

It is recommended to replace it once every two to three years, because the effect will deteriorate after a long time, so that it is easy to appear scale in it and easily block the waterway, and accelerate the service life of the thermostat to decrease, I hope to help you hope to adopt.

Car antifreeze oil. It is usually changed once a year.

Antifreeze is also called coolant, which means coolant with antifreeze function.

What it does is:

1. Maintain the basic stable temperature of the engine, prevent the engine from overcooling or overheating, and can also play the role of anti-rust and waterproof, and protect the radiator and cylinder;

2. If it is not replaced for a long time, it will deteriorate, the anti-rust function will be reduced, and a large amount of rust and dirt will be precipitated in the radiator, which will seriously lead to the puncture of the radiator pipe or the blockage of the core. So we recommend checking every six months and replacing it every 2 years or 40,000 km.

Most family cars are replaced every two years or 40,000 kilometers. The full name of antifreeze is antifreeze coolant. As the name suggests, it has both antifreeze and cooling functions.

50% of the world's engine failure problems are caused by the cooling system, and the coolant is closely related to the cooling system, that is, antifreeze. At the same time, it should be noted that the composition of different brands of refrigerant is different. In order to prevent other chemical reactions that may occur with different substances, which will affect the effect of antifreeze, it is best to add antifreeze of the same brand when adding antifreeze, so antifreeze is also one of the important parts of the car.

First of all, antifreeze has an antiseptic function. Because the engine cooling system contains 5 metals, which are cast iron, iron, aluminum alloy, steel, copper and solder used to weld the water tank. Generally, the cylinder block of a car is cast aluminum, the cylinder block of a large truck is cast iron, and the material of the water tank is mainly copper and brass.

Antifreeze comes into contact with these metals all the time, so it must have anti-corrosion properties, and low-quality antifreeze can seriously corrode metals.

Secondly, antifreeze prevents boiling. Due to the high summer temperatures, the temperatures of the engine-related components are even more frighteningly high. If ordinary pure water is used as the cooling material, it is easy to boil at high temperatures, causing the engine to overheat and fail.

Professional antifreeze has a high boiling point and basically does not boil, which can better ensure the safety of the engine. However, this powerful performance is ignored by many car owners, who believe that antifreeze is ineffective in the summer.

It should be noted that before replacing the new antifreeze, it is best to clean the liquid channel with clean water and drain the old antifreeze. The specific operation method is to add clean water to the antifreeze recharge tank, then pour the clean water into the water tank, so that the clean water continues to flow through the engine cooling system, and then idle for 3 5 minutes to let the water circulate. The water that starts to flow out of the kettle is a little pink, continue to pour in clean water until the water that comes out is clean.

Be careful not to forget to remove the heater hose and drain the water from the heater tank.

Generally speaking, it is best to change the antifreeze of the car every two years; It can effectively protect the cooling system of the car, and will also prevent the generation of scale, have a relative heat dissipation effect, and will also protect the engine.

Under normal circumstances, the antifreeze should be replaced once after the car has traveled 40,000 kilometers; It prevents the engine of the car from being frozen and damaged, provides some protection for the generator, has a heat dissipation effect, and can also resist water scale, which can prolong the service life of the car.

Car antifreeze can generally be replaced when the car has traveled about 40,000 kilometers, and if your area is below minus 25 degrees, it does not need to be replaced; It is a coolant with antifreeze function, which can make the car continue to be used in the state of particularly low temperature in winter, and can also ensure that the car's refrigeration system does not freeze in low temperature weather.

It needs to be replaced every year, and the main function of antifreeze is to resist low temperatures and better protect the engine cylinders.

1. The antifreeze of the car is changed every two years or every 40,000 kilometers.

2. The function of antifreeze: to provide antifreeze protection for the hair and vertical training motive to resist the low temperature environment; Provides efficient heat dissipation; Prevents the coolant from icing and cracking the radiator during the cold winter shutdown, freezing the engine block and the cylinder head.

3. Precautions for the use of antifreeze: the level of antifreeze needs to be checked regularly, and if it is lower than the lower limit, it needs to be replenished in time; Observe whether there is turbid precipitate in the antifreeze, and if there is turbidity, it needs to be replaced in time; Different models of antifreeze have different colors and cannot be mixed; Before winter, it is necessary to measure the freezing point of antifreeze to prevent it from freezing.

It is enough to change the car antifreeze once every two years. When the antifreeze is matched, you must choose the brand, to see whether the preparation of the antifreeze is clear, but also to see the concentration of the antifreeze, if the local temperature is relatively low, you should choose to guess the 70% concentration, but also pay attention to the model of the antifreeze.

You can change it every two to three years. To choose some big products of Naihao brand, you should also choose some suitable for Changpeixing's own car. Xilin is very good, and it also has a very good quality search, and it will not freeze at all, which is also a big highlight, and it is also the reason why many people buy it.

minus 45 degrees. There will be no problems at all.

The antifreeze of the steam mammoth is changed about once a year or so; Choose the best choice, choose the anti-corrosion, choose the one with strong functional force, choose the anti-rust one, and choose it according to the condition of your vehicle.

Generally, it will be replaced once in about half a year, so that it can be better to protect the car with some liquid, and you can also maintain the car according to it. Some farm vehicles are more suitable for antifreeze.

The biggest headache for drivers who use coolant is limescale, which adheres to the metal surface of the water tank and water jacket, making the heat dissipation effect worse and worse, and it is also difficult to remove. High-quality antifreeze is made from distilled water with anti-scaling additives. Not only does it not produce limescale, but it also has a descaling function.

If the scale in the tank is thick, it is best to clean it thoroughly with a tank cleaner before adding antifreeze. The recommended replacement cycle for genuine antifreeze will vary from vehicle manufacturer to manufacturer, but most manufacturers recommend that car owners replace their vehicle's antifreeze every 2 years, and some manufacturers say that the replacement cycle for genuine antifreeze is 4 or 5 years. It can be replaced according to the actual use, because it is not a big problem to walk an extra 10,000 or 20,000 kilometers or extend the service life for a year and a half.

Automotive antifreeze, also known as coolant, helps to reduce engine temperatures. Because the engine generates a lot of heat when it is working, 60% of which will be distributed to the surrounding space through the cooling system. Water and methanol coolants have a low boiling point and boil easily.

If the vehicle works in conditions with boiling coolant, the engine can be damaged or even paralyzed even for a short period of time.

Antifreeze can prevent freezing in winter, so it is also called antifreeze. The temperature in winter is very low. In order for the car to continue to be used at low temperatures in winter, some substances that can reduce the freezing point of water are added to the engine coolant as antifreeze to prevent the cooling system from freezing at low temperatures.

For this reason, people sometimes refer to coolant as "antifreeze" or "thawing".

When replacing with a new antifreeze, all old antifreeze in the car must be released before adding new antifreeze. When replacing, it should be added through the water pipe of the tank (radiator), which allows the antifreeze to flow into the tank quickly. Fill the antifreeze tank for about 10 minutes, then fill the antifreeze tank with antifreeze and then refill the antifreeze for another 10 minutes.
