Re-examination of antifreeze: the surprise was better!

Half of the antifreeze sold is unfit for use — these were the findings of the study two years ago. 17 checking of newly acquired samples, experts found out how the situation has changed.Alexey Revin “driving”ExpertMichael Kolodochkin “driving”Expert

Examination of antifreeze, we spent a year and a half ago, has revealed an alarming situation on the market of coolants: many of them were highly inflammable! Moreover, to distinguish between combustible from non-combustible when buying impossible. After all, in appearance it is not clear that instead of expensive ethylene glycol manufacturer used a cheaper mixture of glycerol plus methanol, which boils at 64 °C.

What happens inside a hot motor with this antifreeze? Low-boiling liquid produces cavitation: when boiling creates air bubbles that explode, gnawing the metal particles from the block, liners, nozzles, vanes of the pump. In addition, there are steam tubes, and antifreeze ceases to circulate, which can lead to overheating of the motor. And if the methanol is boiled off, the remaining aqueous solution of glycerol, and will freeze in winter. The consequences in any case was bad — the engine will need expensive repairs.

The results of the previous examination confirmed the content of methanol in the half antifreeze. To do this, didn’t even need the chromatograph, which determines the composition of the liquid. When we measured the boiling point we just burned antifreeze. Normal fluid should not burn.

Buying the most popular antifreeze, even this time we tried to fire them. And no liquid from the twelve broke out. Do manufacturers no longer use cheap and harmful ingredients? We decided to take a run at one of the suburban market, where he bought half a dozen cans. The result is two fluid, Nizhnekamsk Sapsan and Dzerzhinsky Uniх, broke out! (As always, remember: the results of our studies apply only to specific samples of products purchased.)

However, a remarkable trend emerges. If two years ago half available on the market antifreeze was bad, now such times-two and obchelsya. Us is twice as nice. After all, that threat of antifreeze became much smaller, there is our merit. Our expertise not only help to buy good products and components, but also encourage producers to carefully monitor the quality of their products.
