Towing with electric fan

I’m thinking about doing an electric fan conversion in my 2015 1500 5.7 Hemi to help free up some Hp and gain some MPGs.
I’m wondering if going to an electric fan will cause any overheating concerns while towing heavy loads or a travel trailer.
Anyone have experience or thoughts?

Welcome to the forum... I've used an efan for years mostly without issues. Controller failed after a couple years and was upgraded. On the highway the efan is off. In town or just idling the engine temp cycles between 186 and 203. If I think about it in town I overide the controller and just turn on the fan and let it run keeping the temp around 194. I don't tow so can't say how well it'll work. I suspect it'll maintain temperature at a reasonable level. Being supercharged I can run hot on a long boosted pull.

Thanks! I don’t tow often and when I do it’s mainly stretches of highway. I wonder if I do have any overheating issues, would adding an additional fan in front of the radiator to push air would be any help or just unnecessary strain on the electrical system
Haven’t really found a definitive answer on why Ram opted for a mechanical fan on the Hemi motors oppose to going electric 🤔

You should be fine. If you don’t overheat in town with an electric fan then it sure won’t on the highway as the radiator is getting a ton more air flow than a fan will give it.

IMO.... It would be just another thing to worry about. You will never have to worry about the factory manual fan because it will never fail......If it ain't broken don't fix it.

Mark, you are suppose to be rolling down the road with all that fresh air blowing through the radiator....
