Just be careful about using the manual switch in conjunction with the temp controller, mine threw a couple fuses from the temp controller trying to kick on when I had the manual switch turned on (fuses for the manual switch to be specific), not sure if that is isolated to my fan/controller/wiring or if it may happen to everyone, that's the main reason I just let my controller handle everything now.

To set mine I looked at the min and max temperatures that the controller activated at and then how far the **** turned (from lock to lock), did a little math and decided that I need to turn it x/y of the way to get the temp I wanted. That got me super close to what I'm running now, just had to slightly tweak it so it wasn't running too much.

I took the radiator cap off and let the truck warm up with a food thermometer stuck in the radiator neck. When the thermostat opened and the radiator started flowing, I let it get 5 degrees higher and turned the adjustment **** to turn on the fan and left it alone. Works great. I suck at math, so fltdriver has me beat! lol

So, I just got my e-fans installed today (all day project for me!), and they are working fine with the exception of coming on with the A/C. I hooked the green wire from the controller to the "DK GRN/ORG" wire at the compressor. There is also a "PPL" wire there, is that the one I should have hooked up to? Any help is appreciated.

Well, here's an update. I drove today, over 92 degrees today. I lowered the setting a little bit. It was actually set around 1/3 from the lowest. Fine until I hit traffic again. And the temp started climbing to the middle mark.

I got home, and parked in a nice sunny spot at 92 degrees outside temperature and again it started to get up past middle mark. It only went down on the street cause I started moving. But for sure, if I left it running in the heat, it would have gone way to the right high mark.

I put the shroud back on, and repeated the test and got the same results. It went to middle and I waited for it to go past middle and that's when I cut the engine. It would have overheated just sitting idling by in the hot 95 degree weather.

I figure I can't be driving around and hit unknown non moving traffic on the freeway so I took it off and put the clutch fan back on. Temp didn't go past a 1/3 afterwards.

I have a feeling that the fan just isn't strong enough. I'll have to look for OEM dual fans like unit505 mentioned for under a hundred bucks.

It was good for me to do. I learned A LOT about wiring things up. And now I learned to take off a radiator fan. I've managed to be an expert at taking off serpentine belts. I also now know how to get at the water pump in case I need to do that in the future.

So not a bad exercise. I'm sure I'll be getting another fan once I get funds but making sure its very powerful. I don't want to be stuck in LA traffic overheating! (But I am south of LA which we don't get that much traffic as they do). And the best part is all the wiring is already done. I have everything zipped tied and taped up in the engine bay.

I used the same fans unit505 did and got them for $40 (my junk yard charged $20 a fan, instead of for the entire unit), grabbed mine off of an 04 sebring sedan simply for the fact that I've got an 04 convertible and they use the same parts and I figured hey why not be able to swap some parts if needed. Any Late 90's mid 00's dodge/chrysler sedan will have that fan.

Great thanks! You wouldn't happen to have pics of it? Wonder how it is attached.

Last post on the first page is how I mounted mine with the OE radiator, when I went to the 2-row I left off the metal strapping that was between the fan and the rad. I had to cut one of the mounting hole brackets off of the fan to install with the single row radiator but it would have fit and worked out perfect with the two row that I have now.

I just drilled through the fans surrounding and bolted it to the top of the radiator, as will as made a support for the bottom and top. Pretty primitive mounting setup but it's worked flawlessly so far. I did also use a heavy duty zip tie on both sides of the fan surround to help minimize movement.

sweet writeup! I'll have to read it all later today. Thanks!

Last year I installed a 4 row brass and copper radiator purchased at Oreilly. The coolant would be cooled down so much from running thru the radiator that the temp gauge would drop a few letters when the thermastat opened. It was low quality because when I went back for the second warranty unit they no longer stocked the 4 row. It held 3/4 gallon more than a stock 2 row.

I found there is no substitute for extra capacity in the cooling system. Your existing Efan might be enough with a larger radiator. Just a thought.
