How to install E-Fans

[dwmmatt23]

So how the hell you end up with a $40 fan? Come on share your secret

Are you serious? I paid $140, which is $40 more than the $100 you said you paid at a junkyard

Hey guys, question for you. I've seen a few posts on this thread that says the conversion works with the 34" radiator. Are you measuring width or top to bottom? On my '02 4.8 Yukon, the radiator is about 42" across the front. Does that mean I'm S.O.L.?

It's the width that's measured, the 34" radiator measurement is the actual finned part of the radiator. If you add the tanks on each side of it like you did, you will have 42" for total width!! You have the bigger radiator which means you will have no problem doing this mod!

Whew!!! Thanks for clearing that up. Now just need to get my BB tune, and I'll be good to go.

Okay, I have an 2000 Yukon Denali, I am wanting to do this too... read this thread, and ther momre I read, I got more confued somewhat.. lol...

Now, I went to junk yard today, and they had an 06 Chevy pickup of sometype. It did have the electric fans. they want $80.00 for the fans. Is this a good deal, and will it work with what I have? I measured my radiator and came up with 42" total. So I guess its the right size. If I measure the other one I want to get it out of, and its the same size, does that mean it will work? or do I need to look at something else?

And then what else do I need to get this all goin and working.

Please excuse all the noob questions. Still trying to cabsorb all this, etc...

Thanks in advance,

$80 is a decent price id guess, they are $165 with shipping new on ebay. you can get the wiring harness, alternator pulley, and tune from blackbear. i believe thats all youll need.

 

[Rivieraracing]

$80 is a killer price, as long as they work and look like they are in great shape, ****** them up before they disappear!! If you never put them into your truck, you could easily make you money back with profit by selling them for more!!

Is your body style the same as an '01- '06 or is it the same as a '99? I believe that was the transition year and if it's the older style then I can't guarantee that the fan will fit your radiator exactly like the '01-'06s!

Hard for me to tell, but from looking at your signature pic it appears you have the OBS (old body style) as the '99's, so if that is so I'm not sure if the fans will fit the same as the NBS trucks!! Let us know what you have and maybe someone else can chime in for you!

 

[vonneffdobermans]

Yes, mine is the older style. with the barn doors on back. Its still in the truck up there. did not know if I was to go up there and take it out, if there was a way to determine if it will fit in there. Like a measurement for the bolt holes, etc... or if it will fit on the radiator support on bottom the same?? Since it wasnt a tahoe, yukon, suburban, etc.. and was in the 06 chevy pickup, if there was a way to tell... It looks as its in great shape, no damage. and if it does not work, I can get my money back, even if it doesnt fit, they will giove money back. Just dont wanna have to go thru all the work for nothing, then have to put it all back together again.. lol...

If you know anything that may help, please let meknow. Cause I dont wanna wait too long and have it gone...

Thanks for the help so far, and hopr to get this goin soon..

Spikey

Can anyone side which is better dorman or flexalite?! im assuming only thing different is the price tag but before i buy id like to know

 

[01Konvict]

Dorman 620654, its dual 7 blade fans for the NNBS trucks and costs $140. Also there not extremely loud to me. Remember only one fan comes on High at a time and when both are on there on Low only.

 

[candyman74]

dorman 620653 and 620654 fans in 01 tahoe

so either of these two fans, dorman 620653,620654 will work in my 01 tahoe with the factor fan wiring off of a 05/06 chevy?

I would also like to know that. I'm getting ready to jump on the e-fan bandwagon.

 

[01Konvict]

Yes both of those Dorman Part # will work on the larger radiators (34"). The factory harness (05/06) will not work on 00-03s. You need the harness from blackbear, nelson, ls1fans, or make your own. Then you will need the PCM flashed to activate the fans.

Can't speak to the Flexalite fans but the Dorman fans are top notch. Looks totally OEM, perfect fit and run much quieter than the stock belt drive fan. Best mod ever! (I'm running the Blackbear harness) I'd buy them again in a second.

i got the 620654 from rock auto for like 140 and a black bear wiring harness and under drive pulley ,which is a must and it works great. went to home depo and got 2 bolts to mount it and zip tied the harness to the power steering hose. i wish i would have done this along time ago.

Instead of being driven by a belt attached to the engine, it runs off one or more separate electric motors, so it doesn't drain off horsepower. Other claimed benefits include less wear on the water pump, reduced fan noise, improved A/C output, better gas mileage, and improved cooling. An electric fan, however, operates off a temperature sensor, so it kicks on when needed, and automatically runs faster when the temperature rises.

Exactly why I havn't done this Mod yet. Sound like alot of work... Where the hell do you get the PCM Flashed?...
