Title: fan removal '04 4L
Post by: Elsifer on July 19, 2009, 03:40:06 PM: So how can I spin the big nut, without the whole pulley turning? I don't want to put a set of chain grips on the pulley and mess it all up.

I am following this writeup: http://www.4x4xplor.com/fan-clutch.html

Any thoughts?

Looking for a cloth strap-wrench in the meantime...

A pain in the posterior!

Electric fan setup nearly complete. Convenient of flexalite to not include an overflow bottle bracket, or extra holes in the shroud for ease of controller install.
Tomorrow...

As for the cut-off switch, I was going to put a switch on the ignition sense line to interrupt the fan, rather than run more wiring.

Post by: Elsifer on August 04, 2009, 09:23:59 AM: WOW!
I should have done this years ago!
Taking the mechanical fan off really livened up the power out of the 4L, 5th gear has power and use for other than cruising!
Though I have to relearn how the motor sounds without the roar of the fan, she is quiet, and powerful!

Not to mention fuel efficient! I went from 300-330 km on a tank of gas (city or highway, didn't matter); and got 400 on the highway!! I made Revelstoke from my place in Beddington with 10L to spare! Before, I would have to fillup in Golden.

Highly recommended for ALL 4L users!

Title: Re: fan removal '04 4L
Post by: Elsifer on August 04, 2009, 10:55:22 AM: I bought a Flex-A-Lite Wrangler Extreme setup from Mopac, about $330. http://www.flex-a-lite.com/auto/html/jeep-wrangler.html

As for XJ's, I don't know, I thought they had 2 fans, one electric and one mechanical. There are some pretty good XJ/ZJ/WJ resources out there on the internets, you could try there. http://naxja.org

Post by: Corey on August 04, 2009, 03:50:26 PM: I have mine on a 40amp relay and a 40 amp inline fuse from a car stereo install kit to a switch in the jeep I run it all the time. Temp never goes past 100 and it has 2 speeds. I went pit this weekend first to mcleans and then to burnt timber all in one day going hard! Not one over heating issue.
