Why did seasoned Soviet drivers pour sugar into the engine cooling system?
The era of the carburetor “Zhiguli” and “ZiLkov” has long gone into history. However, some techniques used by motorists of that era can still be useful.

The cars that drove en masse on the roads of our country 30-40 years ago, of course, were much simpler in design than electric cars, hybrids and, in general, all modern vehicles – packed with electronics, security systems and other fruits of the evolution of the automotive industry. But despite all this, automotive internal combustion engines still retain the cooling system virtually unchanged in their design. Its “improvement” over the decades has largely been reduced to the appearance of only new antifreeze compositions.

This tells us that the ‘wills of our ancestors’ in the field of engine cooling can still be successfully used by modern car owners. One of them concerns sugar. Nowadays it is difficult to imagine, but at the end of the last century many cars drove with plain water in the radiator. Especially freight transport. Wandering to his dump truck on a winter morning with a bucket of boiling water – a very normal ‘picture’ from that time. Because the water was drained from the car’s cooling system at night so that it would not freeze.

“Tosol”, a Soviet antifreeze, was used mainly on passenger cars. But sometimes it did not save the system from freezing – the quality of this fluid was also Soviet. That is to say: unstable and unpredictable. In addition, at that time it was considered normal to add water to the cooling system, which was initially filled with antifreeze, when a noticeable drop in the coolant level was observed.

And then one day a cunning driver realized that the boiling point of a solution of ordinary table sugar is higher than that of pure water. And sweet syrup freezes in noticeably stronger frosts than “ash-two-o”. From this it was concluded that a solution of sugar in water can be used as a substitute for ‘antifreeze’.

Garage geniuses have empirically discovered that to obtain homemade antifreeze you need to dissolve more than a kilogram of sugar in two liters of tap water. Less concentration does not work. In moderate frosts, the resulting product did not turn into ice and well coped with the functions of cooling the engine in the heat. Except it was impossible to drive with such “ersatz antifreeze” all the time. The sugar gradually broke down, decomposed, and after a few months the homemade “antifreeze” had to be replaced.

Now, in an emergency, such a recipe may be in high demand. For example, when you urgently need to add coolant to the system, but normal antifreeze is not available, because the situation takes place, for example, somewhere far from specialized car shops.

This does not mean that every car owner now has to have a five-kilogram bag of sugar and a jerry can of water in the car. Of course not. But knowing how to prevent the engine from drying out with improvised means is useful in any case.
