Default Which thermostat is best?

['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.

I would say 195* as well. That is what I have in mine here in Oklahoma and rarely get above 210*.

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:

Why not replace the hose while you are in there? Especially if you don't know how old the current one is. Like you said, it's cheap... cheap insurance. You can always keep you old one as a backup.

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.
