Electric fan in a 2nd generation Ram
I've got my e-fan hanging inside the shroud. Mainly because the Taurus fan and shroud doesn't cover the entire radiator. If you turn it on its side, you'll get a little more or less 1/2 coverage. Just not good enough coverage for a single fan.
I'm only running the low side since it's winter and there is no point running the e-fan when I've got 60+mph 20 deg (or 7 deg) wind blowing through the radiator.
I've also got an adjustable thermostat from AZ turning the fan on and off. For $18 why bother with those that are $60? Besides, use a relay to control the fan and the controller only trips the relay.
The foam pad that comes with it is way to dam big to use under your hose, but I'm thinking about a thin bead of gasket sealant should do the trick. But for not I've got the temp probe attached to the rad just below the upper hose. Set the on temp and secured all the wiring.
When playing with the cooling capabilities I've let the engine temp hit 210, trip the fan and in less than 30 seconds the dash gauge is reading 170'ish.
I'm connected to a switched 12v right now, but I'm thinking of feeding the temp controller straight off the battery to get the "finish cooling" cycle after the key is turned off.
edit: I'm not sure if I gained any MPG's but one of the reasons for the e-fan conversion is shorter warm ups in the winter with out daming up the rad. When at 60-75mph the fan does not run, so I'm sure I do gain some mpg's. If your running your e-fan 100% of the time you might be better off leaving the stock mech fan since you'll prob see the same numbers, but now your putting extra strain on the alternator.

the foam pad can be used, im usin mine, jus takes a little work to get it in right,
if your battery is any weak at all, i wouldnt suggest leaving switched 12v. mine is straight to the battery and theres been a few times it wouldnt want to start back. i have a new battery now with no problems tho
i just installed my electric fan but the only fuses i could find were hot all the time i hav it fused to a hot spot now so i have to unplug it if i have the truck off were did you guys hook the fuse up to and were does the green wire go i couldnt seem to fine a spot in the A/C i dont need it know so im not to worried but i would like to have it a finished can you help me out?
