So for the last month or so I had been chasing a temp fluctuation issue and yesterday, thanks to many people on here and a few on NAXJA I finally got it licked.

People do your self a favor when you change your tstat, go to the dealer and pony up the $20 and buy one. The dealer tstat looks and feels like a better unit and they seem to make a huge difference in jeeps. I was running a Stant SuperStat and the thing could not keep a consistent temp. It opened late and scared the crap out of me a few times. At warm up sometimes my jeep would climb up to 220 then operate back in the 203 range. It then would swing from 210 down to 194, over and over again.

Yesterday I popped in the dealer stat and the variation is gone. It warms up to 203 and stays there. It also seemed that my heat put out a little better too.

So to the guys on here that helped me out, thanks a bunch!

 

Yea I'm having the same issue my tstat is staying open. During the week I'm gonna get a dealer one and flush out the system one time
