What is the purpose of a temperature unit sensor will it make your radiator fan stay on constantly?

The temperature sensor you're asking about is a device that
detects a temperature above a specific point, usually somewhere
around 180F, then closes the contacts of a switch. The switch can
directly run a motor or it may be connected to a relay. If the
contacts of the temperature sensor switch become damaged they can
weld together and the switch will stay on constantly.
