SuperSickSS Posted August 6, 2016 Report Share Posted August 6, 2016 Hope someone can answer this for me. I want to upgrade to dual electric fans but the mechanic said I will need a new radiator. I read that it wasn't necessary, but he said I won't install unless you change the radiator? Someone please help me out. Also is oem fans the best to go with? Or does anyone recommend an aftermarket brand? Thanks. Quote Link to comment Share on other sites More sharing options...
lucky03 Posted August 6, 2016 Report Share Posted August 6, 2016 I don't have to change the radiator. Not sure why he said that. I bought mine off of amazon they work great. You will have to get your computer tuned for the fans and you will need a harness. I got both done through Zippy. Quote Link to comment Share on other sites More sharing options...

SSmoothSilSS Posted August 8, 2016 Report Share Posted August 8, 2016 (edited) Whats he smokin? OEM fans are fine, sometimes you can't find them with the harness but there a few places that make them. Give me time and I try to remember who.

SSmoothSilSS Posted August 8, 2016 Report Share Posted August 8, 2016 Found it, keep your eye on ebay, I bought the OEM fan and harness for $125. http://www.nelsonperformance.com/fan-harness Quote Link to comment Share on other sites More sharing options...
jsanders347 Posted August 9, 2016 Report Share Posted August 9, 2016 Question. Is this just to free up some horsepower? Sent from my SM-G930V using Tapatalk Quote Link to comment Share on other sites More sharing options...
EXGM Posted August 9, 2016 Report Share Posted August 9, 2016 (edited) Question. Is this just to free up some horsepower? Sent from my SM-G930V using Tapatalk Yes, even when the fan is not engaged it is still using power to turn. They typically don't turn as fast when they are not engaged. Besides freeing up a few extra hp it helps with fuel economy.... This is why now you see electric fans on all trucks now.

2003_SuperSport Posted August 9, 2016 Report Share Posted August 9, 2016 That mechanic is either A. trying to scam you into spending more money on the truck or B shouldn't be working on vehicles if he really thinks you have to change the radiator to put in efans. I have a 2003 SSS and I got my dual Efans out of a early 2000's model grand Prix from the junk yard. I wired it up myself and used a relay wired into the PCM. Because early model SSS's were clutch fans and all SSS's use the same PCM there is a open plug on the PCM for the efan which you wire up from power supply to relay then to fans and computer. Then you program the computer to run the efans. Quote Link to comment Share on other sites More sharing options...
SuperSickSS Posted August 15, 2016 Author Report Share Posted August 15, 2016 Thanks for the help guys. Yeah that's what I thought. I wish I knew how to change myself. Anyone in LA that wants to make some extra bucks installing? I want to start doing some upgrades but need a good mechanic who knows these trucks well.

dieseltech320 Posted September 6, 2016 Report Share Posted September 6, 2016 hmmmm reminds me of a mechanic that use to work in my shop. he would quote jobs like that cuz he was guaranteed to bust the original radiator while doing the swap so he would say before starting the job gonna have to have a new radiator since he knew it would end up broke. must of been this guys thought process. lol its easy. I did mine myself, even built my own harness. which I wouldn't do again. it sucked. lol Quote Link to comment Share on other sites More sharing options...
