Hey everyone! I have a pair of eletric fans from a late-model Camaro on my hands. Fans were taken out of my father's project truck and are still in great condition. In his truck, we ran the fans to two separate relays and an adjustable temperature switch that was remotely mounted on the firewall. The switch had a probe that was mounted on the intake in one of the water jackets.

Instead of getting rid of these, I wanted to put them in my '07 F150. I check Troyers website to look at the ones they offer, and how those fans work, but couldn't get any concrete information. I have an idea of how I could wire everything, but I am wondering if it will affect the computer in anyway negative. Not only that, would the alternator be able to handle electric fans, or would upgrading it be beneficial. I was thinking about wiring one fan to one temperature switch that would turn the fans on at a lower degree (mainly when in traffic or doing in-town driving), and then have the second fan come on at a higher degree (might never come on, essentially being used as a back-up).

Could anybody offer up any suggestions or recommendations on the setup? Will it work? Is there a missing link in all of this? If these fans can't be used, then that's okay. But like I said, I have them now and don't want to get rid of them.

 

Hi.

If those are out of a 5.7 litre application, they are approx 12" fans. Don't know the CFM, but I would suspect them to be marginal for cooling a much larger, heavier vehicle's cooling system adequately under all conditions.

Regardless - just go to http://www.spalusa.com/ and download their installation manual for the SPAL-PWM fan controller. You will see exactly how to connect the thingys lol!

Alternatively - Search this site - there are many articles with advice & diagrams - 'Patman03SprCrw' is one fella who's done these.. he's a good kid, and takes a lot of abuse from me with class.

Good luck, bud.

 

Great! Thanks for the reply! Spal really made it seem alot more simple than I thought it would be. The reason why we yanked them out of my father's truck, is that the fans were causing the battery to drain quickly. Since they were both wired to one temp. setting, they would both run and the voltmeter would steadily begin to drop over a few days. GMs 105 amp alt. just doens't seem to cut it. From what I understand about the controller though, it varies fan speed according to engine temp., correct? So in essence, there should be a constant 12v being drawn out by the fans use? Not only that, since I have two fans, I could wire one as the secondary and the main one as the primary. I will probably give SPAL a call this week to see if I could iron out all the details.
