Apricot yielded plentiful yellow foam,
and the air smelled like a barber shop.

The best coolant (coolant) is water. And the heat capacity is excellent, and the price tag is missing as a class! In addition, it was water that for decades allowed drivers to feel like real men: unscrew the cork in winter, pour boiling water out of the bucket, and knowingly start the ice motor … The modern driver is deprived of such nuances of communicating with technology. He sometimes opens the hood with difficulty. And the fact that the coolant is able to freeze or boil does not even think. Meanwhile, it was precisely this danger that prompted us to experience modern antifreeze. Rather, the fact that in this capacity they sometimes strive to sell us. A dozen samples purchased are pictured. The numbering is borrowed from the test reports and is not related to the rating of drugs.
In this device with a solid name (Bauman-Frome device), the temperature of the onset of crystallization of the coolant is evaluated according to GOST 28084–89:
ANTOSOL? ANTIFREEZE? COOLANT?
The correct name for what we tested is “low-freezing coolants”. According to GOST 28084–89, the only regulatory document in Russia. You can discuss its pros and cons for a long time, but one thing is clear: he is the only protection against outright bodyagie. Formally, the standard serves as the basis for the development of regulatory documentation for new fluids, but it also has a loophole. In other words, if I do not make coolant based on ethylene glycol, then I have the right to ignore this GOST in general. Today it is fashionable to produce various products and preparations, guided not by standards, but by their own technical specifications. But how can one not conform to one's own technical specifications if they enter only knowingly win-win information in them? Here and then “antifreezes” arise, freezing already at –20 ºC and boiling before the teapot on the stove. The main pests that cause such disgraces are glycerin and methanol. Our opinion on these components is given below. Why did they talk about them just now? The answer, of course, comes down to money: glycerin costs a penny, it is very beneficial to use it. But methanol is trying to draw out the deficiencies of glycerol, while adding its own …
Evaluation of foaming properties. Everything is simple here: the less foam and the faster it disappears, the better the liquid

WHAT TO BUY?
When every second pack carries a hidden danger, giving advice is difficult. Therefore, we recommend using the results of our tests. Well, if the liquid has the approval of a respected automaker, you can safely trust it. However, it is useful to clarify the status of such approval on the official website of this manufacturer.

REFERENCE
Glycerin is added to the coolant because it is very beneficial: it is almost free! But, alas, viscous, especially in the cold. Therefore, methanol is called for help. But he boils already at 64.5 ºC and even dissolves everything in a row. The result is deplorable.
FROM CHECKED COOLING LIQUIDS ONLY HALF SAFETY
WHAT AND WHY CHECKED
Appearance
Assess color, the presence of impurities and sediment, stratification, etc.
Density
It allows you to identify the product and, in particular, to confirm the quantitative content of ethylene glycol and water.
The temperature at which crystallization begins
The temperature at which the first ice crystals appear in the coolant, and the product begins to transition from a liquid state to a sludge (porridge-like mass).
Fractional data
This indicator “will not miss” the coolant with the addition of monohydric alcohols or other low boiling fractions.
Corrosive effect
The effect on the metal components of the cooling system is taken into account. Note that GOST does not take into account the cavitation effect of the coolant.
Foaming
It is checked whether the foam will create global overheating zones on the engine surface at certain temperatures, pumping speeds and antifreeze turbulence.
Rubber swelling
Evaluation of the impact on rubber (softening, swelling, drying, cracking and hardening).
Hydrogen indicator
Shows acidic or alkaline environment. Indirect indicator of antifreeze corrosion.
