When you said it cooled down at idle I considered the fan polarity, but said to myself "there's no way, don't suggest that, you'll sound dumb"..

Now on the side note, when I was testing thermostat, I put in to boil my 170F gearhead thermostat and for kick of it factory OEM 180F one in the same ***, as water was coming up to boil, gearhead one started opening 10 seconds faster than OEM

Now to the potential bad news.
Yesterday after driving around I check my coolant reservoir and it was little under LOW mark, so figured it settled after coolant change, so I added to the HIGH mark.
Now after morning drive to work and lunch drive I checked again and its little below the LOW mark again and engine is hot, so it will only get worst after it cools down.
I think I have a problem on my hands...
warped head or blown gasket?

Definitely check your oil and coolant. Usually with a blown head gasket you will see oil in the coolant or coolant in the oil.
Best of luck and hopefully you just have a loose clamp.

It also could be the system is burping itself. Don't get discouraged yet.

Yes, I am defiantly going to keep my eye on it next few days, drive easy and see if it stop, so far it drives good and engine runs very good.
Not a lose clamp, I also checked for drips, parking spot where I idle is clean.
Take it little bit at the time
Not over util it's over :)

Well damn. Check both fluids for contamination as was stated. Also you can check plugs for liquid contamination. Tailpipe smoke etc. If things got too hot you probably have to change both. For sure especially with lubricated turbos I would get fresh oil. There are test kits or a trusted shop tech can test if you determine it necessarry. Fingers crossed.

You'll have to do this a few times topping it off until all of the air pockets make it back to the tank. It should stabilize withing a couple of days with heat cycling, depending on how much you drive. But also keep an eye out for head gasket/coolant consumption signs as other have suggested

Just brainstorming, if you were to put the front of the car up high on jack stands and open the radiator cap, from a physics standpoint, the air should travel up and out of the highest point.

Yep, all great points, fingers and toes are crossed, I will keep topping it off every day and see where I am at by the end of the week.
Thank you all for kind words of hope :)

Keep you posted, thanks again!

Quick update.
Last night after driving to work and back (about 40 mile round trip) coolant was just tad under the LOW level line, added about 4-5 OZ of coolant.
This morning I set my phone on to video record exhaust pipes on cold startup, did start, few rews, absolutely no smoke of any kid, like car was not even started, zero steam or smoke.
Will keep checking lever today tomorrow, keep you update

Thank you all again

You'd be shocked how much that thing will suck down. For one car I had, after radiator flush, I had to burp it 3 times, and it took darn near half a quart more.

Don't distress just yet.

LOL, WOW.
SO when the dealer does the radiator flash service, you have to come back 3 times to check in?

My coolant temps 10F cooler than before, before I would watch temps on the hot 90F day be like 190-200
Now Im 175-185 with AC on
Sometime I see temp needle drops just hair below the normal position and climbs back up, I never seen that before, wow
