I was wondering what exacally I need to install E-fans? I know im going with the FAL 16'' fans but im not sure on the sending units. What is the best way to wire these bad boys up. If I need to wire both fans to the AC or just one. Thanks for the help in advance.

 

I wired both of mine to the a/c. I ran an ignition wire from the fuse box, and the hot and ground directly to the battery. I also have a manual override switch to turn the fans on/off with the a/c, so they arent running while going down the highway with the a/c on.

 

Any type of variable speed controler needed? Adjustable thermostat? Whats the ''ideal'' way to set them up?

 

How are you using the truck. If you go off road through deep water y ou need to hook up a power disconnect so the fans will not try to run in water. If you run on the street and do not "work" the truck a thermosta only with an AC on swich may be all you need.

I use my truck primarly as a commuter during bad weather. For my efan hookup I have the passender side hooked to the AC and it is set as the 5 degrees lower than the driver side fan. The driver side fan is wired with a manual override so I can turn the fan on at any time. I also have a relay set up with a switch so I can disable them if I need to. I am using the Troyer fan setup. I have had one controller fail closed so it stays on all of the time - now that cooler weather has set in I have diabled it. E-fans are nice to have but they can have issues. BTW: I have had thes for about 5 years.

 

Who makes a good thermostat? Should I use an adjustable or set temp?

 

my Hayden adjustable is working fine. got it for 18 bucks from auto parts store
