2004 Mustangs come stock with electric radiator fans, right? do electric radiator fans take horsepower from the engine when they run?

I am just curious because the tune I got set the fan to run at cooler temps, so the fan runs more.

 

Yes it's an electric fan. It doesn't cause parasitic drag like A/C or power steering. You'll want it to come on at a lower temp. and turn off at a higher temp.

 

awesome! just the answer I was looking for, thanks. The tune was done by Justin at VMP, so I don't feel that there is anything to worry about then.

 

yeah your good he knows what he's doing

 

Yeah electrical fan is much better then mechanical as it does not take HP from the engine to run.
