It is too bad about your 6.7L. You see people boasting of 500 and up on efan but also quite a few having trouble at those levels.
I'm assuming yu already went to the bigger radiator. That would seem like a good idea too. I've always had this impression that the single row radiatior is just on the ragged edge of being adequate even for stock 5.9L.
One thing I've always wondered about but it's not like I know anything about the subject....
Most of the aftermarket 2nd gen efan shrouds butt the fans right up against the rdiator. I think that means the air gets pulled in kind of a donut shape pattern, through the radiator, where the flan blades are. If that's true then not very much of the radiators surface is getting air pulled through it. Maybe not ideal.
Those aftermarket shrouds are quite a bit a bit different from the factory shroud since it had a pretty big space between the fan and radiator. I was wondering if the extra space, the factory shrouds have betweeen the clutch fan and the radiator, acts as a bit of a plenum allowing air to be drawn through the whole radiator. That is quite a bit more radiator surface area to have the air drawn through than just in a donut shape like with the aftermarket shrouds. ie I think spacing the fan away from the back of the radiator could allow more efficient BTU removal.
Naturally, that led to me wondering about how I could do this to mine. It probably wouldn't take much for someone good at metal fab. I'm a different story. I'll probably have my best luck trying to modify and kludge off the shelf objsects. I've found a few candidates I could picture bolting to the back of a modified version of my existing efan shroud...for example maybe even seal it with some rubber gasgeting...https://www.summitracing.com/parts/hre-34304m
Fairly accurate assessment. The stock mechanical fan/shroud will draw more air thru the radiator directly in line with the fan, but, it will still draw some air thru the rest of the radiator as well. The fans right up against the radiator? Not so much. Originally Posted by Ugly1

Essentially, the more space between the fan, and the radiator, assuming a full shroud, the more effective it is.
Thank you guys for all the help and responses. I bought 1x 16in fan and an adjustable fan controller and ofc all the stuff needed to do the wiring. This is my first DIY type of project Like fabrication or wiring. I have no idea how it’s going to go but I’ve been learning a lot.
I don’t think this single 16in attached directly to the stock RAD will cool enough. I already bought it tho so I’m going to give it a shot. Later down the line I’d like to buy a bigger fan, or dual fan with much stronger relay and wires. Just incase.
this is currently what I bought. From Amazon
16in Amazon fan - https://a.co/d/2vQixD2
Hayden Adjustable - https://a.co/d/7hGpkCA
ove seen people use bigger gauge wires with 2 relays and also a digital adjustable set.
the fan shroud that was listed on this thread looks awesome. It says fan size 15 in?
I’d like to beef this up eventually. Im currently just jumping into it and learning as I go. Starting cheap and learning how to use all the heat shrink and crimping, all that lovely stuff.
As for the truck plans. This truck is and will be a Daily driver with power. I intend to add performance mods but nothing insane. As for towing, no. The most weight this truck see’s is my lawn care equipment. A push mower too not a rideable one.
and occasionally hauling junk from houses. Simply, I just want a fun daily. I also enjoy drifting, well sliding around in the rain… it’s a truck I know.. but it’s fun

Actually, trucks, being very light in the rear, and rear wheel drive, lend themselves to drifting/sliding rather well. For me though, it is generally unintended.

yeah mine is unintended, sometimes.

I was mostly just posting that shroud as an example for user dodgetruck2 to illustrate my theory about what I think may be an upgrade to the type of system he might be using. That probably wouldn't be my pick for you until possibly later down the road as a possible upgrade.
I and I think most people on the forum use shrouds by companies such as TCP Performance which hold dual 16" fans. Not sure if TCP sells just the shroud these days as they seem to want to sell the whole kit on their website. Though I think there are probably plenty of options on ebay.
Back in my day they didn't have anything cool like this or I probably would have this instead of what I have now....This might not be a bad thing for someone like you.....https://www.ebay.com/itm/18557221230...Bk9SR5jEnvTIYQ

broooooo!!!! That is actually awesome. I’m definitely going to look into that. With the radiator too.
That radiator I linked, btw, is the one with the transmission oil cooler. If you have a manual you may want to look for the one without the oil cooler on it.They have those too.You'll find there are slightlyless expensive ones too but that one seems nicer with better components like it's brass valve.
