The difficult conditions in which many sectors of our country’s economy find themselves today, including the automotive industry, give a free hand to unscrupulous manufacturers of technical fluids.
As you know, car coolants are among the most popular “consumables”, the demand for which increases noticeably with the onset of the autumn-winter season. This factor plays into the hands of unscrupulous companies, which during this period try to ‘push’ counterfeit goods and even downright substandard goods through retail chains on a large scale.
The diagram here goes something like this. First, in underground laboratories, businessmen develop their own coolant formulation from inexpensive components. It is then documented in the form of certain technical conditions (TS). Then they start slaughtering their product and distributing it in large quantities.
One of the popular options for “antifreeze” body agitation is to replace expensive monoethylene glycol (MEG) with a mixture consisting of cheap glycerin and equally cheap methanol. Both components are extremely harmful to the cooling system. For example, glycerin promotes an increase in corrosion activity, especially in the cooling channels of the cylinder block. In addition, it has a high viscosity (it is tens of times greater than that of ethylene glycol) and increased density, which leads to accelerated wear of the pump.
To somehow reduce the viscosity and density of the coolant, companies add to it another harmful component – methanol. Let us not forget that this alcohol belongs to the category of dangerous technical poisons. Its use in the production of consumer products is prohibited by law. However, this is only one legal aspect. The use of methyl alcohol in the cooling system is also technically unacceptable, because methanol simply disables its parts and components.
The fact is that an aqueous solution of methyl alcohol at temperatures above 50 ° C actively interacts with aluminum alloys, destroying them (see photo above). The rate of such interaction is extremely high and is not comparable to the usual corrosion rate of metals. Chemists call this process etching, and the term is self-explanatory. According to experts, individual elements of the cooling system components (for example, the water pump impellers), which are also subject to high dynamic loads, are destroyed by methanol-glycerin antifreeze in almost one season.
Considering the rather high risk that car owners may encounter when purchasing a low-quality product when choosing the right coolants, experts recommend purchasing them only from trusted brands. And there are many of them on our market, and among them there are well-known foreign manufacturers. These include in particular the German company Bizol, whose product range includes such a popular item as the Coolant G12+ antifreeze concentrate.
Experts position this product as a new generation composition based on high-quality MEG and a package of special additives made from organic carboxylic acids. According to experts who tested Coolant G12+, this antifreeze has excellent temperature properties, which allows it to be poured into the cooling systems of various types of engines, including gas engines.
The properties mentioned above are retained for a long time, and over a wide range of operating temperatures. This makes it possible to successfully use Coolant G12+ in cars driving in the northern regions of Russia. As the developers themselves note, antifreeze effectively resists electrochemical corrosion of metals, as well as high-temperature corrosion of aluminum alloys.
