Perma-cool e-fan setup

nater006 · 06-19-2007, 07:48 PM

Posted a bunch of info on this fan setup in the past but took some new pics when putting in the new radiator today. I decided I hate the pull through connectors. What substantiation do I have for this? Nothing... they were just out of stock.

(They work fine!)

Fan: 14" Perma-cool. Pulls 2950cfm @ 9 amps.
Radiator: some lifetime warranty replacement aluminum dealie. Nothing special. Free. See "lifetime warranty"
Fan mount:
(1) 4' 1/4" thick aluminum stock. ~$16 at Lowes.
(4) 1/4"x1" carriage bolts. $0.07/apiece at Lowes
(8) 1/4" washers. Very cheap.
(4) 1/4"x1.5" machine screws
(8) 1/4" nuts

Grand total on the above: ~$20. Not even.

Clicky clicky for larger pic-ys.

Plain and boring, pre-screwed-with aluminum radiator. Except for the 2 holes drilled in top, and the 2 drilled in bottom

Shhh, don't tell the auto store.

1/4" thick aluminum stock. Probably a lot less elsewhere but I was there so... $16. Holes drilled in it match with the radiator holes.

I cut small spacer pieces from the aluminum stock. Still had ~1' left from the 4' piece. This keeps it off the fins and allows my fancy carriage bolt heads to not be pressed against the fins. Obviously, holes for the carriage bolts are not drilled yet since the fan I need to use to mark the holes is... still in the truck.

Okay, I forgot a pic after putting the carriage bolts in, before putting the fan on. Here is the fan, mounted up.

Mounted in the shroud. Again, totally not visible unless you lean behind the shroud and look at the radiator.

Don't rip on me for using steel hardware on aluminum - the screws are all stainless so they and the aluminum shouldn't react.

I don't have a drill press or I'd have considered drilling holes throughout the aluminum stock for better airflow, etc. Honestly, the mounts block so little, and there is a minor amount of space between the core and them so they aren't totally blocked. If the truck overheats from those, well, something bigger is going on. So, you could probably get away with drilling them out a bit.

Also, the fan looks a little used. It's been in the truck for probably 3+ years now with no difficulties whatsoever. Obviously, I just re-used it so it looks a little dull/corroded against my shiny shiny radiator

Looks pretty good, I recently joined the efan mod club and I must say I am very pleased with the results...not only is it quieter but I have picked up an easy 1.5mpg just from the efan swap alone.

nater006 · 06-19-2007, 10:32 PM

Heck yes. I loved the argument when people said "That mod costs $100. You can't justify a minor mileage increase"

I remember calculating that @ $2.50 a gallon (pipe dream, now), increasing from 20 to 21mpg takes 16,800 miles to pay off. Uh... I'm past that, and then some, and then some... and some more..

@ $3.00/gallon, it's 14,000 miles to pay off $100 assuming a 1MPG increase.

e-fan away... it's worth it for the reduction in noise alone.

BudRacing · 06-20-2007, 12:17 AM

Still waiting on mine to pay itself off. It should be any day now.

Snake Eater · 07-16-2007, 11:32 PM

I wish my mods would pay for themselves like that. Stock mpg was about 21 with easy highway, now its like 15mpg if I drive it VERY easy. lol

BudRacing · 07-17-2007, 07:44 AM

The lift and tires probably didn't help too much though.

yea. lol Just the difference in tires from stock makes it feel like your trying to tow 5k lbs. everywhere. They really slowed it down and started sucking the gas.

BudRacing · 07-17-2007, 03:23 PM

Yeah, I read your other thread about gearing. 1300 @ 65 was it?

1500 @ 65 would be ideal for me on the hwy though....

Yea but it will climb hills without downshifting though. lol

With the turbo you give it a little more go pedal, boost builds and it takes off up the steepest hills without downshifting. lol It will run 7psi steady at part throttle up hill keeping the same speed.

5 years and counting, here. It still owes me like $6.38, I think.

Yeah, I think I've got a looong way to go. I didn't gain much if any mpg.

Maybe I need to get some other things straightened out.

~~runuover~~ · 10-12-2007, 05:15 PM

what is the part number for your perma cool

s-10hater · 10-12-2007, 05:48 PM

that is how i was gonna mount mine when i do it . looks good and strong !

nater006 · 10-12-2007, 06:11 PM

It's a 19114. The 16" version should fit and work as well.

Summit's P/N is PRM-19114. You might find it cheaper elsewhere. It was only $80-85 or something when i got mine a few years ago but it's obviously gone up.

I don't have a drill press here or I'd have put holes in it for slightly improved airflow and to lighten it a little (haha, right). It's 1/4" aluminum and is pretty rigid - rigid enough to not flex and bump the core at all. The same thickness of narrower alum stock would likely work every bit as well. Just wasn't available when I needed it

The airflow doesn't really seem affected and the fan seems to do as good of a job as when it was mounted to the radiator core with the plastic connectors. For $20, works fine for me!

BudRacing · 10-15-2007, 08:18 PM

It's probably doing a better job actually... and your fan will thank you too. If they're not tight enough (which is hard to do with those zip ties they supply) they start warbling then eventually get off balance and before you know it you need a new fan.

nater006 · 10-15-2007, 08:44 PM

The cable tie items they supplied seemed to do a decent job and all, but my radiator core started leaking right where one of them was mounted, so I decided to go with a mounting method that kept the fan off the core as best as possible. Problem is, these radiators just don't have tons of strong areas.

The tanks on the side are weak (I'm sure more than a few people have had leaks spring up there), and the core isn't super sturdy either.

Oh well!
