The path along which the coolant flows depends on its temperature.
When the engine is not yet warm, the coolant flows through a small circuit that passes through the engine and through the heat exchanger. Intake manifold and starting automation (start-up enricher) additionally included in the small coolant circuit
At temperatures above 85-87°C, the thermostat opens "big outline", which includes a heatsink. If the coolant temperature continues to rise and reaches the value of 93°C measured in the radiator itself, the radiator fan turns on and assists in cooling.
