The engine cooling system is a set of devices that allow you to maintain the optimum temperature of a running internal combustion engine. Overheating can disable the machine since its  components retain only specified characteristics up to a certain temperature threshold. The cooling system consists of a cylinder block water
jacket, a cylinder head, one or more radiators, a radiator-forced cooling fan, a liquid pump, a thermostat, an expansion tank, connecting pipes, and a temperature sensor.
