radiator fan goes on together with ignition in cold weather
If you take a moment while visiting your neighborhood Dodge dealer, try to turn the fan with the motor off. It will definitely spin, so the clutch is most assuredly disengaged when the motor is cold. When the motor is cold, why would there be any need for cooling?
No matter what the fan will always spin. Even a disengaged fan will spin. If your fan spins freely for more than 1/4 of a turn when the motor is off, you have a bad fan clutch. If it doesn't spin at all of if the blade wobbles front to back you have a bad fan clutch, or a water pump.
In some instances there is a small electric fan generally used for transmission cooling or emergency engine cooling. It is a smaller radiator, but a radiator nonetheless, which is why I keep wanting that clarified.
