Ya, where is your fan sensing temperature to turn on/off, and what temp is it set at? What is the CFM of the fan you used? Do you know your fan was definately coming on while you were towing? You could hook up a small LED on the switched side of the relay to see when it is trying to turn it on and off.

All this sounds like your 'stat is stuck open.
All good questions, my e-fan is set to come on at 180* or when I turn on my A/C, my tranny fluid is brand new as I just had a tranny service done. My sensing unit is pushed through my radiator right where the upper hose meets the unit as was instructed by Black Magic.
Don't know if it is necessary or not but that what the Black Magic instructions suggested to do.
Couple of questions...
What do you have for a temp control unit? location?
Do you have the entire shroud sealed off to the fan or is the fan just dropped in place with gaping holes all around? The outer perimeter really needs to be sealed so the fan can pull air across all fins of the radiator.
Honestly, fo me, the stocker does the job and I wasn't risking my Lifetime warranty for the hassle of an electric fan assembly. The only bonus with the electric fan are the few hp gained at the crank...
lastly, how's your transmission fluid?

Only if there is no separate condenser, where the A/C dumps heat into the cooling system. The Ram has separate A/C cooling.

Hi ya'll,
So I recently changed jobs and got a nice little bonus which I decided to put into my hobbies for once. Starting with a nice gun safe, a couple of new guns and most of all my Ram. Since day 1 it has always been a little sluggish due to it's size and weight being a Mega Cab with a Hemi. So besides some cosmetics ( nFB nerf bars, custom fitted floor mats, dash cover etc ) I installed a Wicked flow exhaust true dual in/out cutting out the restrictive y-pipe, Black Magic e-fan, new 160 amp alternator to keep up with the fan, 180* t-stat and all new HOAT coolant, new serpentine, new spark plugs( regular copper ones )a tranny tune-up, Superchips programmer and best of all, 4.56 gears w/ a Mag-Tech cover.
Now I'm running alot cooler, my temp needle used to run in the middle of the gauge and now runs at a 1/4. I came on vacation with my family, hooked up to my boat and the needle immediately started rising, I barely got to the house when my needle was at 3/4. It is a 4 hour drive to my vacation house in Lake Havasu, AZ which is about 115* outside, but the truck ran like a champ all the way here. I went to O'reilly's yesterday and bought a new radiator cap (16#) and it helped a little but the needle still goes over 1/2 and the house is only a couple miles from the lake. Without starting to replace the whole cooling system I thought I would ask for help since this forum is usaully pretty good with their ideas. Any and all help would be very much appreciated and thank you in advance for your time.
