2.1.4.4. Thermostat

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


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