How to make an anti-freeze

I poured another bottle of anti-freeze into the washer reservoir and thought that a whole canister of 5 liters was spent on a trip along the highway to the dacha and back (about 250 km in total)!

I consume fluid moderately, but it still turns out a lot.

. But we are engineers! So you can try to make this liquid with your own hands.

The Internet is replete with recommendatory articles, they say, "Do it yourself." But the advice there is usually mediocre. But first things first. Let’s analyze the options.

To do this, you need to understand how anti-freeze works.

The mechanism here is simple. .

In practice, most often seasoned with dyes and flavors. Detergents are sometimes added.

Previously instead of isopropyl alcohol. As a result, it turned out that vision is lost from methanol, and drivers actively get drunk from ethanol. After all, some even managed to drink this bormatuha.

How to make an anti-freeze

You can add something like regular salt to the water. It contains sodium, which is the so-called flux. But salt will destroy all structural elements of the car and significantly accelerate the corrosion of metal elements. Truth. It has similar properties in terms of its ability to lower the crystallization point, but is less "toxic" to vehicle systems. True, the cost will also be noticeable with large volumes.

This means that our main task is to lower the crystallization point of the system, but at the same time not cause alcohol intoxication in the driver, poison him with dangerous reagents, and not disfigure the car’s systems with something like a salt solution.

I strongly advise against using ethyl alcohol.

Most of the articles on the Internet are filled with similar advice. Technically, this is possible and even convenient, but the breathalyzer can make a sound. Then tell the traffic police that you are doing the anti-freeze with your own hands. So, this advice is sent immediately to the furnace and it is no longer good.

we also immediately weed out. Its harmfulness is greatly exaggerated, but it is still a poisonous substance.

You can use vinegar. But. For the preparation of non-freezing you need. Such a mixture will keep the temperature up to -10 degrees. This is not the worst and widely known advice. But it’s also not very efficient.

There are also craftsmen who use ammonia, but I do not advise doing this either. First, it stinks very nuclear. Secondly, the paintwork of the car will thank you very much. The advice is again ineffective.

It remains that it would be optimal to use the same isopropyl alcohol and mix it with tap water.


The cost will be commensurate with the finished product. This is due to the fact that when manufacturers (even garage ones) make "non-freezing on stream", they.

For liquids up to -30 degrees , you will need to mix equal parts of IPA and water. To save money, you can buy IPS on an industrial scale.

It turns out that there are not so many options. It turns out that doing the anti-freeze yourself is not always profitable. It is much easier to find a cheap concentrate and save on canisters by using home water or buying canisters in bulk.

It would be interesting to know about your experience in this matter! Write in the comments.
