I've seen posts about replacing the thermostat and housing only with an OEM part...any thoughts on aftermarket ones?

I would recommend the Mopar OEM. But they have been on back order, for the better part of a year. My Dealer installed the Duralast in mine, and it has been working just fine. The Mopar are available now, through Mopar parts online. I just ordered one for a spare.

OEM

If you are unable to get an OEM thermostat, the Mahle thermostat #T123695 will work. Mahle is the OE supplier for Jeep.

Beat me to it. A Mahle brand on IS an OEM one.

One thing to note is I've personally seen 3 aftermarket thermostat's fail, either not fully opening all of the way, or they fail closed and don't open at all. But the aftermarket housings are okay, just not the thermostat itself. I put a Mopar thermostat into an eBay aluminum housing and it's been great.

Fed-X just dropped mine off, and it is the MOPAR, not a knock off. So now I have a spare if needed.

That is a great price!!!!!! I am just happy to find one.. Will probably never need it, which is also O.K.

I’ve had a motorad for two years with no issues.

I bought a duralast from advance auto and it's been fine

Same here, with no issues! From what I can tell, mine starts to open at about 203°, and is fully opened at 215°. This is what it is suppose to do!

ready to install mine as soon as temps increase, prob March. Still worried about getting the air out though.

 

[Srlesq]

Several ways to get air out. Great advice here on forum and manuals to do it right first time, but I found myself burping it until i was satisfied. Good luck in your decision as to which antifreeze is best.

I have the antifreeze thing down as I threw a code, but topping it off didn’t help so thermostat replacement which I already bought is my next move I’ve reviewed a lot of videos about burping and will buy the funnel, but still concerned about the air probably a bit prematurely, but that’s how I am.

I figured I can always hit a local repair shop if the code still exists afterwards

 

[Srlesq]

I didn’t see what code you have in this thread but I had a p0128 code that resolved once the thermostat was replaced.

 

[Artdnj]

Yes, that’s the one. No issues with heat or anything just the code. I cleared it a couple times through jacan but it reappears.

 

[Srlesq]

That sounds familiar to my experience. Check the operating temp of the coolant, mine was at like 183 before the change, now I run between 203 and 222

 

[Artdnj]

Is the lower temperature indicative of a faulty thermostat
