Looking for an efan for 02 5.9
Did you fab up a shroud? or just mount the fans to the radiator?
I did the same thing on an old Wagoneer I had and fab'd up a shroud that worked pretty well. My concern is that I use this truck to pull my travel trailer about once a month and do not want one of the ebay fans to fail me out on the road pulling a trailer.

to be perfectly frank: I mounted the fans directly to the radiator with ties.. and left the oe shroud in place.. reason: I wasn't sold on this 'efan' thing and wanted to keep things returnable until i felt them out..
they draw around 15a each when they fire, but settle back to around 10a to run them.. I used the probe temperature as the trigger, and have them set for around 182~185*.. (i run a 180* stat).. at idle, such as stuck in traffic, they toggle 'on', and run for about 10~15 seconds, and toggle off for around 30 seconds.. I've never come close to overheating..
all this said: when the fans fail (and they've lasted a LOT longer than I would ever have expected), I will construct a shroud and use a controller that toggles power based on temperature.. such as a dakota controller.. this eliminates ANY concern for spike.. they kick in barely moving as the temperature breaks, say, 160*.. then slowly increase speed until moving wide open at, say, 190*.. you can even have one operate in this manner, and the other kick full on if the temperature jumps to, say, 190*.. this eliminates the concern about power uses, and protects the fans by adding juice in a modular fashion.. they are DC motors, so they turn based on juice received- the capacitors are usually blown on a DC motor when full juice is laid to them...
I will always use efans, from now one.. here's why:
I did it for one simple reason, and that reason alone, which was BACKING a heavy trailer a pretty good distance into a barn, where space was limited and the only way to do it was that long back-up..
I would near overheating, and I hated it.. every time this would happen.. I went to efans to keep the air moving through the rad no matter the direction of movement, or the speed.. it worked, and payed off in spades.. furthermore: there was an unexpected side benefit- torque off the line was improved by what my levi's dyno tells me is at least 30#'s.. right off the line, as in idle, as in- the PERFECT spot for these motors..
if towing is your use, I'll go so far as to tell you you're crazy if you DON'T do it.. the added torque off the line is worth it all by itself..
i'll offer this as an install tip:
use heavy gauge wiring, in shroud tube, w/ soldered and heat shrunk connections from the battery to the controller, and med/heavy gauge from the controller to the fans themselves.. all heat shrunk, soldered connections, wrapped, and affixed permanently.. the wiring is the important thing.. the fans are almost consumable.. I put my controller behind the passenger headlight, and the probe in the rad below the rec'd location, which makes it about 1/3 the way down to the bottom directly above the bottom tube..
oh- and protect all of it, including your PCM/alternator with relays and fuses.. don't be shy with those.. I've installed a 60a relay, and two 40a fuses on either side (overkill), as well as 25a inline to the fans themselves.. (again, overkill)
good luck dude!!
edit: the fans are procomp 16" S blades.. here..
