System of cooling of the engine
The system of cooling of the engine works on the following algorithm. While the engine is not heated-up, cooling liquid (OZh) is pumped over by constantly working pump only in a head and the block of cylinders, and also in the heat exchanger of a heater of salon. At OZh temperature increase to a certain level the thermostat opens a big contour of cooling and OZh circulates in addition through a radiator (from top to down) and is cooled with air passing through it. At achievement of temperature of OZh of higher value the electric fan of system of cooling which creates an additional air stream through radiator edges for more intensive heat removal from it turns on.
Before work in an impellent compartment, especially in the field of the radiator fan, surely disconnect a negative wire from the storage battery and the socket of electroconducting of the fan. The fan of a radiator can turn on because of effect of heat conductivity even at the switched-off ignition.
Do not open a cover of a broad tank of OZh before complete cooling of the engine in order to avoid a burn hot liquid or its steam.
If necessary to open a cover of a broad tank at the hot engine wind it with a thick layer of rags. Uncover slowly, gradually reducing a vapor pressure.
