is it worth the time and money to change my 07 5.4 to an electric fan or just let it be? they are like $50 and if i do it is 1 big fan better than 2 small fans? thanks

 

I put in a fan from a 90's Ford Taurus, with an adjustable fan controller, wired correctly and only one fan wired at the moment. It feels differant driving, but I doubt I freed up much horse power. I pretty much did it for the hell of it after doing it to a 79 Bronco. The idea sounds good. Maybe someone with technical knowledge could chime in.

 

The change over will free up some room in front of the engine.
A sensor controlled fan will help with the airflow through the AC condenser when you are in city traffic.
You get rid of some parasitic drag on the serpentine belt.

Where did you find a electric fan for $50?
That sounds cheap.
What kind of quality do you get for that price?

 

I'm guessing it's $50/fan, and fan only. No relays, controllers or wiring looms. If I'm wrong please post a link as at that price I could use a new project. The best benefit (for me at least) would be the better A/C cooling. Summer down here is brutal with the insufficient A/C in my rig.

Do some searching on here, I remember several posts where people put in cheapo fans and controllers and ran into problems with them dying fairly quickly. Also check out Troyer Performance, they sell a solid kit.

 

it was fan only here is a link to singles and duals

i put one on my 84 (not this brand but close to it with aluminum fins) and its been great but i dont know how much harder a 5.4 modular motor is to cool then and old 300 6 cylinder

 

Benefits:Negative:
measure your radiator. then get 2 seperate fans with associated controllers. make sure to get the kind that run off of temperature switches. set one fan as the "LOW" temp fan of about 150-180F, and then one fan that runs from about 190F and higher.

traffic and idle is really the only time you need a fan. when you are driving along the natural air flow is sufficient to keep the motor cool.

 

yeah i was leaning to the twin setup and i never thought about two circuits for a back up, good thinking!! the controller i use on old blue has no temp numbers, i just started it and when the temp got almost 1/2 i turned the dial till the fan came on, do some show temp numbers and who makes them if so. i got mine at the local parts store and that was all they sold.

Check this one out. I am going to get this soon. I havn't heard of any complaints on this website yet. It does have 2 controllers. Learned about these on this website.

 

it looks nice and well put together but a little high priced, but you get what you pay for. i see they have an under drive pulley kit too, i wonder if i would feel any change from them with the fan kit because that would be over $600 and for that money it better feel faster/more powerfull

 

Dont have one on my 5.4, the old 390 has a 4800cfm dual fan setup that works great. The truck will sit in traffic in 110 degree temps and the temp gauge wont move. have never checked on mileage difs, but prob negligible. One nice benefit I noticed is that I have heat in the winter time much faster. If you do have a elec fan breakdown, you just have to keep moving. Once I had a blade connection get dirty on the controller and it kept the fan from coming on. Keeping the instructions in the glovey helped for troubleshooting.
