7 is constantly pumped through the car (4-cylinder), 8 (5-cylinder) and 11 (6-cylinder) liters of coolant. This is done by means of a water pump, which is driven by a V-belt or toothed belt.
The path the coolant takes depends on its temperature.
When the engine is not yet warmed up, the coolant flows through a small circuit that passes through the engine and through the heat exchanger. Intake manifold and automatic starter (device enriching mixtures at start-up) additionally included in the small coolant circuit
At temperatures above 85-87°C, the thermostat opens the "large circuit", which includes the radiator. If the coolant temperature continues to rise and reaches 93°C, measured in the radiator itself, the radiator fan turns on and helps with cooling.
