I think the Real trick for a TJ is to stick with mechanical...thank god for an iron block and an iron head. Stoopid Taurus fan ran my jeep to boil over more time then I can remember....on the trail....on the road..you name it particularly when you didn't expect it.
I'm not going to drop hundreds of dollars on a fancy fan .... not enough benefit...Taurus fan was good because the whole thing could be done for just over 100 bucks
