Stumped on temps...
So I tackled the job of flushing dex cool yesterday and today. After 6 drain, fill and flushes with distilled water, I added a genuine 180 tstat, peak green stuff and a bottle of water wetter. My temps before at idle were 210-212, after all that, the temps are still in the same area. If I rev it up to about 2500-3000 rpms it'll drop to 194 but won't go any lower. Anyone have any ideas what the issue may be?

You're not going to get much lower than 194 with an "OEM "pressure activated" t-stat. If you want to idle in the 180's I suggest fitting an inline t-stat. There's a ton of info on the board for your research.

You should idle around 197-206ish.
What are you using to gauge temps? Ultra Gauge?

Is the radiator in good condition and not clogged? I have a complete OEM setup on my 02 Kalahari, and I'm at 173F-183F in the winter and 182-193F in the summer.
If you haven't replaced your radiator I'd be willing to bet it's probably clogged up. Or you just haven't got all the air out of the system yet. Park it nose up, let it run until warm, shut it off, and let it sit overnight. Doing that several times should normally be enough to get any trapped air out.

Could it be the fan clutch? It's free to check out. There are a bunch of tips floating around the board and on the web. I know that after the engine has been running and it is shut off, the fan should not make more than 1 full rotation. I think at cold startup and just at idle it doesn't matter much but should be ruled-out anyway.

If it's running warm at idle that to me indicates poor air flow thru the radiator or a radiator that is mostly clogged up and just not cooling properly.
Since you do have an 03/04 style Fan Blade/Fan Clutch that is a one piece unit it would be a nice time to upgrade it to the 99-02 Fan Blade/Fan Clutch that is the normal two piece design. Then slap on a Hayden 2991 or similar Fan Clutch.
