My car consistently runs at an absolutely normal 83dC in good weather, no ac.

Well today it was around 100dF outside, give or take a few. I had the AC on full and on the highway crusing around 85mph for an hour, the temp stayed a hair under 100dC.

I didnt think this was too drastic, so I kept crusing at a good clip. When I took off from a dead stop (full throttle) and got back up to my crusing speed the temp went to about 105dC but cooled back down to around 97 after driving.

Same happens if I floor it to pass someone, it creeps up to 105 or 107 then regulates back to ~97 in a minute or two.

Are these temperatures normal in extreme heat with the AC on? I didn't drive this car at all last summer so I cant tell you how it behaved a year ago.

I just dont want to post here in a few months that I need a new head..

PS: The temp stays at about 90dC if I cruise below 80, but that just isn't the way I drive
