SmthnD1ff Posted February 16, 2014 Share Posted February 16, 2014 I just finished modifying and installing my Renix harness and am very pleased with the results. Unfortunately all that work seems to only be noticable at idle so I have begun searching for my next upgrade and want the biggest bang for my $. After some searching it seems like alot of people have swapped in an Efan from a taurus for relatively little money and completely removed the metal fan and clutch. My 2.5 has the idiot light temp sensors still in it. I have a set of full gauges in it but havent tackled the sensor issue yet. I would like to pull parts from the jy for this so what vehicle am I looking for a temp sensor in? Second question is for those who have done the Efan swap- besides cooling more efficiently were there any other noticable improvements? (MPG, butt dyno, etc) Link to comment Share on other sites More sharing options...
Jeep Driver Posted February 16, 2014 Share Posted February 16, 2014 I'm running an after market fan, switch is a 195 Spal, and a 180 stat. Unless I sit through more than one light cycle, the fan never comes on. I have no tolerance for a mechanical fan............NONE! Link to comment Share on other sites More sharing options...
SmthnD1ff Posted February 16, 2014 Author Share Posted February 16, 2014 Lol Noticable ride difference? Better MPG? And what motor are you running? Link to comment Share on other sites More sharing options...
Jeep Driver Posted February 16, 2014 Share Posted February 16, 2014 I have the 2.5 also. Always looking for every bit of power and MPG. Less wear on the pump. No shroud. No fan noise. I can service my belt or pump without removing fan/shroud. Efan can't bite my fingers. Efan's pull is constant regardless of engine RPM. Faster warm up on cold days. I have it on a manual switch too, if I think it's running warm I can just turn it on full time. Another advantage is I can let it run while the engine is off if it's hot and I want to work on it.......cools down completely in about 5 minutes. For most of my driving I don't need a fan anyway. Not a single disadvantage to an Efan. Link to comment Share on other sites More sharing options...
Jeep Driver Posted February 16, 2014 Share Posted February 16, 2014 One of the things I need to do this summer is replace the HB. Two hoses, two bolts, unplug fan. Less than three minutes and I'll have the rad and fan out of the way. Image Not Found Link to comment Share on other sites More sharing options...

HOrnbrod Posted February 16, 2014 Share Posted February 16, 2014 I have the 2.5 also. Not a single disadvantage to an Efan. Maybe not for the 2.5. But for the 4.0, it requires two Efans, or maybe three depending on the conversion. This equates to more amp draw and a 2nd fan controller. Many ways to do it, but it's a little more work and expense for a reliable and efficient system. But I agree, Efans are better, and it's well worth the conversion in either case.

SmthnD1ff Posted February 16, 2014 Author Share Posted February 16, 2014 With my new harness setup and external voltage regulator my alt is putting out about 14.5V steady- no change with headlights, ac, stereo amp and sub cranked up. Will the draw on my alt really be that bad for a single e-fan run through a relay switch by a temp sensor? Also what temp sensor can be pulled from the JY and are their different ways to install them? I read a thread on JF where a guy had his efan triggered by a chevy sensor wedged in the radiator. I'm looking to do something a bit less ghetto but the seeming simplicity has my head spinning with ideas qnd questions Link to comment Share on other sites More sharing options...
Jeep Driver Posted February 16, 2014 Share Posted February 16, 2014 The problem you will have is combining the correct temp and the correct thread for your application. There are two styles of stat housings, the Renix 2.5 and the 4.0, study this pic, does yours look like this? Image Not Found Link to comment Share on other sites More sharing options...

TheDirtyJeep401 Posted February 16, 2014 Share Posted February 16, 2014 What kind of 2.5 is that housing off of? I haven't seen one that has the place for the temp sensor Link to comment Share on other sites More sharing options...
