Many car owners know the replacement cycle of engine oil, and even know that brake oil needs to be replaced every two years, but it is easy to ignore the replacement of antifreeze coolant. Many car owners do not know what the replacement cycle of antifreeze coolant is, nor do they know how to buy it. Let’s give you some popular science.
How long is the replacement cycle of antifreeze coolant?
It is said that the manual of each car is a "Sunflower Book". Even if you know nothing about the vehicle, just go into seclusion and practice once. Although you cannot guarantee that you know everything about the vehicle, at least you have a basic understanding. So when to change the antifreeze coolant in your car, you will know it by opening the user manual.
Most family cars are replaced every two years or forty thousand kilometers. Of course, this is just a reference replacement cycle. You can change it according to the actual usage, because it is not a big problem if you walk one or two million kilometers more or the service cycle is extended by about one or two years. If the car is strong, you can replace it in advance.
However, if the antifreeze coolant has not been replaced, 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 it will affect the cooling performance of the engine.
How to add antifreeze coolant?
Speaking of adding antifreeze coolant, there is another precaution here, that is, do not mix antifreeze coolant between different brands

How to add antifreeze coolant?
Speaking of adding antifreeze coolant, there is another precaution here, that is, do not mix antifreeze coolant between different brands and models to avoid failure of antifreeze coolant due to different chemical compositions.
In other words, when replacing antifreeze coolant, it is best to choose the same brand and model. If you change to different brands of antifreeze coolant, it is best to emptiate the antifreeze coolant inside the engine in advance, and clean all cooling lines before adding.
How to choose antifreeze coolant? Compared to engine oil, choosing antifreeze coolant is much easier. As the name suggests, antifreeze coolant not only has cooling function, but also prevents condensation at low temperatures to ensure normal operation.
How to choose antifreeze coolant?
When purchasing antifreeze coolant, we can choose according to the lowest temperature of the place where we are using. It is best to have the freezing point of the antifreeze coolant about 15° lower than the local minimum temperature to ensure that the antifreeze coolant strikes when the weather is extremely abnormal.
[General antifreeze coolant is around 70 yuan, and its performance can meet daily use]
For general models, the use of universal antifreeze coolant can meet daily needs, and the price is generally around 70 yuan. This type of brand can be bought and used immediately. The main brands that can be selected are Castro, Shell and Great Wall.
It should be noted that some antifreeze coolant must be used in proportion to water to achieve "effect". Many car owners use it directly without reading the instructions after buying it, which eventually leads to the engine "opening". Therefore, no matter which antifreeze coolant you buy, it is best to read the instructions before use to ensure that everything is foolproof.
Is antifreeze coolant reliable without replacement in life?
Currently, some "lifelong freezing coolants" have been launched on the market. Compared with ordinary antifreezing coolants, their biggest advantage is that they do not need to be replaced during the lifetime use of the vehicle, which reduces the hassle. For this kind of product, I personally recommend that car owners choose carefully.
[The antifreeze coolant with the main "no replacement for life" is priced at more than 1,000 yuan]
Because these antifreeze coolants are often more than 1,000 yuan, they are relatively expensive. Although it does not need to be replaced throughout your life, it is difficult to ensure that there is no need to add it during use. What's more, if the price is more than 1,000 yuan, if it is replaced with ordinary antifreeze coolant, even if the labor cost per replacement is 50 yuan, the total cost of replacement is about 120 yuan.
I believe everyone will forget it when it comes to this point. The cost of replacing ordinary antifreeze coolant 10 times is equivalent to a bottle of "lifelong antifreeze coolant". If you change ordinary antifreeze coolant 10 times, you will have to run 400,000 kilometers. If a vehicle crashes and causes the water tank to explode, then more than 1,000 yuan will be wasted. Personally, this expensive product has more gimmicks than its practical significance, so it is better to choose carefully.
Can water replace antifreeze coolant?
The harm of using water instead of antifreeze coolant is not as serious as the market says. If it is a short-term emergency use, adding water is OK, and it will not damage the thermostat or block the cooling waterway. In the racing yard, there are many racing cars that directly use water as coolant. Moreover, if you find that the antifreeze coolant is lower than the minimum value and there is no antifreeze coolant to add around you, you can also add water to temporarily replace it. After all, the reduction of antifreeze coolant is mainly caused by the evaporation of moisture.
After seeing this, you should know when to replace the antifreeze coolant and how to choose. If your antifreeze coolant has not been replaced, hurry up and it will be too late to regret it after the engine is "boiled".
