**Update**
over 275miles I achieved.... 18.26mpg the catch is that I had 3 days
of stop and go driving in intercity cleveland.. Pre E-fan I'd estimate
16.5-16.8mpg for that kind of driving. That holds with the 1-2mpg increase
I was expecting. I'll update again after I get back from maine. (probably resurrect this topic :)



First off I went to summit racing and special ordered a " PRO-67017
Electric Fan, Single, 15 in. Diameter, Puller, 2,800 cfm, Black, Plastic Universal."

Price was 120$ it includes wiring and thermostat. You also have an option to wire a manual switch to the fan.
Install went pretty well.. removing the old one was a pain.
The dam autozone clutch tool was the wrong size... but with a little ghetto fab
Later and voila.



After that bit of brain storming (after 30min of trying with vice grips)
We had it off in about 5min.

This pic was at my dad's shop.. extra credit if you can name the machine behind the fan.


Why is it that radiators seem to get so dinged.... *sigh*


The almost finished product... I still need to wire the A/C clutch turn on wire..
if someone has a pic of where thats at(or detailed instruction).. it would be much appreciated. Oh and wire loom is coming soon too :)

 

Looks good is it a magic machine?

 

lol its a type of high tech machining... hint ;p

 

Nice. I am getting the Black Magic #150, same as your fan, I think...only more expensive, lol.

I wanted to get the Black Magic, as it mounts on the endges, and not through the core like I read/thought the Perma-Cool like your's did.

You're 67017 kit came with the top/bottom mounting brackets?

 

CNC machine?

 

CNC is a generic term basically reflecting computer control of the axis vs manual control...

You can have cnc anything.. ie drill press.. mill

Adam its a Proform.. not permacool.
It came with clamp on brackets and also bolt on brackets.. no through
core mounting(ick)
I could have bolted it on... or clamped it on with either set of brackets

It also has a shroud and gasket, thermostat,built in relay. Its extremely easy to wire even has a special tab to put a manual control switch on it in about 3seconds.

summit racing sells them as does jegs.. but they are special order..

Overall I'm happy so far I have been getting about 17.9mpg over the last 4000
miles so I'll be tracking the mileage now to compare.

I was actually cracking jokes about my truck being a big shop vac(anyone remember how loud john griggs fan is?)

I asked my dad if he had any split loom. He replies sure a whole roll.. So I go and look and its the 2" diameter stuff.. So I said hey that will go great with teh shop vac noise of the fan.

I was really expecting it to be Hela loud.. being straight blade and all but its not. Also pulls 15amp or so continuous (not sure peak startup draw)

al least i tryed....like the fan though. i would love to but one on my truck, but kinda scared to do the wiring

 

'Eh, Pro-Form, Permacool -- they all begin with a "P"! Shoot me.

 

looks liek a mitsu wireedm or ramedm machine, most likly a wireedm...

 

*Ding* a winner.
Its a mitsu 90C Wire E.D.M

 

Look at that eye...shoot dang

Have you have seen any difference in the gas mileage yet?

 

kewl install...the machine is used to bend tubing or steel bars

 

I'll update this after I get 500miles post fan install. with gas mileage.. I'm expecting +1mpg so hopefully 19mpg now. :)

A Wire ELECTRONIC DISCHARGE MACHINE..

basically a brass wire is constantly going from a spool to a trash can..
as it passes though the part to be cut a spark jumps off burning though the
metal.. It can cut anything conductive.. carbide.. already hardened
tools, graphite.. etc.
It can be accurate to +- .0001"
Normal tolerances are more like +- .0005

Made everthing from all sorts of Tile making dies to a tire sidewall checker
for goodyear on it.

I have the same fan and installed it a few weeks ago, helped out with at least +2 mpg, I got 270miles on not an empty tank, it didn't even get to the empty line, so I figure at least 300+ miles on a full tank.

 

The "AC-allowed" wire from the mode selector switch on the dash AC panel is solid purple. You can tap it in the harness to the PCM (pin 41). You will need to tee into this wire and extend it to the positive of the fan relay coil with a diode in series. Without the diode, the fan thermostat will backfeed the purple wire and enable the AC compressor whenever the fan T-stat is closed.

Many people use the compressor clutch wire (gray/white) to trigger fan operation. It also requires a diode to keep the Efan T-stat from controlling the compressor. Even though I was advised to not wire it this way, I decided to give it a try. It doesn't work very well at all when the truck is stopped because the AC condensor doesn't reject enough heat during the compressor-off/fan-off cycles. I have since moved the wire to the AC-allowed wire (purple mentioned above) and now the AC works great, even when stopped. The only downside is that the Efan runs continuously whenever an AC-allowed mode is selected.

I would like to add an automatic control that disables the Efan above a set road speed (30 MPH, for example) but I'm still looking for a way to do it.

 

oh ya...

 

Maybe i'll just wire a switch to it lol. and if the air isnt cool enough I'll flip it.
:)

The fan is sorta unique it has all the relays and such built into it..
do I still need to use a diode?

Rand

 

It needs either a diode or a separate relay to prevent the backfeed. Maybe yours has an integral diode or relay for that purpose. Don't know. What did the instructions say?

 

The instructions were a 1 page sheet..half of which was for a different
fan kit for a mustang...
half were for warnings.. and like a 4x2 section on the page was all the instructions for the actual fan i got.
It said tap the ac compressor positive wire.. nothing about a diode.
and it included the wiring.

 

Sounds like it might have an integral diode or relay already. I would wire it up and see if it works. Be sure to verify that the fan T-stat is not forcing the compressor to run continuously. That will lead to overcooling and evaporator core freezup.

 

Subscribes...

Looks good, I like that the fan comes with all the bracketry needed and the price isn't too bad.

 

I have my AC wire tapped into the AC compressor right by the fan, it doesn't make the compressor run, has nothing to do with it. My install seems to be working real well.

 

updated

 

nice 2 mpg incresse that is awesome ... im hoping for the same ... i can not wait for my efan to come in the mail! congrats bro!

 

Is there a shorter belt required for this installation?
