Ока 360 ; Куда-то уходит ОЖ

In this video I tried to show the reasons for the gradual decrease in the coolant level in the engine; the reasons that I encountered myself, and there were more than one. By the way, these are not all the options for the loss of coolant without obvious traces that are immediately visible. I will tell you about the very first attempt to solve this problem on my Oka in the story "Oka 360; Expansion tank. Refinement". Well, and of course everyone knows that in terms of the undetected decrease in coolant, the cause may be a trivial broken cylinder head gasket.
