Re: Radiator fans cycle when heat turned on

On most cars setting the heater to the defrost position turn the AC on and the fans will run. Try the heat in one of the positions that doesn't defrost. That is normal for most cars & trucks, and yes it will take longer for the engine to reach normal temperature. Of course if you don't have AC my answer isn't correct.
