this is for my 93 wrangler with the 4.0L. I just put in a mechanical temp guage, and the engine is barely getting up to 130*F, so I'm guessing the T-stat is stuck open, or the previous owner took it out, and forgot to tell me about it.
anyway, I was looking, and I found 3 different T-stats that I can get, one is the high temp 195*, medium temp 165*, and a low temp 160*.
my wife use to have an 02 cherokee with the 4.0, and it ran around 210*, which kinda makes me think I should get the 195*, but I was wandering what you guys with 4.0's ran, and was also wandering if maybe the mid range one 165* would be any better or worse?
thanks,
muddy

I'd run the 195 if you want any kind of heat in the winter :bigthumb:

it seems to put out plenty of heat now, even with it being stuck open, but then again, it really hasn't been that cold out yet.
but at less than $5 each, I could always just pick up a couple different temp T-stats, and just see which one works better.

The cooler temp will make more power, but the higher ones will keep you warmer in the winter. I'd get one at either end of the temp range and swap them in the spring and fall.
