Fig. 2.51. Thermostat: 1–engine party; 2–radiator party; 3–the pump of cooling liquid; 4–thermostat; 5–thermostat case; 6–oil cooler (LF engines and L3); 7–heater hose (L8) engines; 8–bottom hose of a radiator

In system спользуется the wax thermostat with a pin. In the plastic case of the thermostat the thermostat from stainless steel is established. When the temperature of cooling liquid of the engine – is lower than 75 °C, the thermostat stops coolant circulation through a radiator for improvement of warming up of the engine. When the temperature of cooling liquid of the engine is between 80 °C and 84 °C, the valve of the thermostat starts to open, cooling liquid starts to circulate through a radiator for stabilization of temperature of the engine (fig. 2.51).
