Does anyone know how to change the on time of the fans. I temp is around 233 when the fans turn on but would there be a way to change the temp to 215? If anyone knows that would be great thanks. Oh would a computer programmer be needed to make these changes?

 

The PCM knows everything & controls everything, reprogramming is required to change fan On & OFF operation. The engine is designed to run hot, no need to worry unless the temp gage goes into the red zone.
