Should Radiator Fan Spin?

The engine temperature should trigger the fan to turn on. It will also turn the fan off once the engine has cooled to under 200 degrees.

Are radiator fans supposed to spin?

Temperature will often determine the time that a radiator fan starts up. A temperature-sensitive switch functions to turn the fan on and off periodically. Radiator fans are designed to start when the temperature of the engine coolant reaches around 200 degrees Fahrenheit.

Why are my radiator fans not spinning?

If the fan doesn't come on, you need to look for a blown fuse or breaker. In older cars, you might have a fusible link – this is wire within an insulated block of rubber. Try to grab the end and stretch it. If the wire stretches, the wire link could be broken and you'll need to replace it.
