The outline of cooling closed with the non-congelation of liquid contains an electric heater, a wide tank, the bomb of cooling the liquid, the thermostat and the ventilator.

Electric heater and wide tank

The electric heater with an angry current has tanks of the artificial material.

The wide tank is done from the transparent material and has designations of the maximum and least levels of cooling the liquid.

Pressure of opening of the valve of excessive pressure in a cork of a wide tank: 120 – 140 kPa.

Bomb of cooling the liquid

The centrifugal bomb of cooling the liquid located in an advanced wall of the cylinder block puts itself in the action for a side belt together with the creator.

Supporter

The supporter with the electric walk of the thermal sensor of the electric heater is located in a drain cork.

Thermostat

The temperature began to open: 85-89 °C.

Temperature of full opening: 102 ±3 °C.
