['01 XJ] My water pump is leaking some- so it's getting replaced here in the next few days. I figured it would be wise to replace the tstat while we're in there. I'll be observing and learning from a buddy of mine who owns a jeep fab shop. I'm a novice mechanic at best. I've been reading multiple threads on here trying to figure out what tstat is best- but it seems like there is much debate about this. Is there a definitive answer? Thanks, and sorry for another thread asking this question. I think I'm gonna pick it up at Napa- here are the choices.

If you do alot of off roading or live in a very hot climate get a 180* tstat. If you live in a place thats not as hot and do the occasional offroad thing then get a 195*. With the 180 your engine will cool down faster and this helps when you live in a hot climate or do alot of off roadin. the 195 will get the engine a little hotter before it starts to cool down so this helps for people that have a cold winter so the cab will get a little hotter then the 180.

Good input. thanks. Should I let the fact that I have an '01 with an original head (171,000 mil) influence my decision? It seems like an 180 degree tstat may lessen the risk of overheating-and cracking the head. I may just be paranoid.

Agreed. Go with a 195 degree premium stat. That is what you Jeep was designed for.
Because I have had poor luck with some (not all) aftermarket stats, I buy mine directly from Jeep and also have had great luck with the Stant SuperStat.
NEVER buy a cheap stat. Think about what they do during their lifetime.

Glad you started this thread breakthecycle, I am going to change my thermostat out this weekend and was surprised at all the choices..
I am planning on using the 195 premium for sure now... When the thermostat is replaced I was going to replace the hose as well. Am I just overkilling this or is this something that makes sense. I do not know when this was replaced last so I thought it made sense for $10 bucks.. I was also going to use the felpro gasket anyone get a opinion on that..??

How would one go about setting up a t-stat poll? A curiosity thing....just a vote and anonymous.
Use a 195F:
Use a 180F: 1
Use a 160F:
Don't use a t-stat:

I say go with 160 degree thermostat!
I have owned 5 jeep Cherokees and every one of them ran hot and did not do well in stop and go traffic with the AC on. I just replaced my a blown/cracked radiator, I believe due to over pressure due to a 195 degree thermostat. I decided to install a 160 degree high flow thermostat and guess what? It now runs consistently under 210 degrees (180-190) in stop and go traffic with the AC on. I also pull a small trailer with my 1993 Harley over the Sierra's and it still stays under 210 degrees.
