Guys, where does your temperature gauge set at after your car is warmed up? My old impala set exactly in the middle of the gauge. The first time I test drove my DTS I thought maybe it was starting to over heat because the needle settles above the half way mark. Lately it seems to inch a little higher than usual and then come back down. Just wanting to make sure what is normal. Many thanks.
Mine will occasionally go to about a needle and a half above the halfway mark, in really hot weather or if I have been driving VERY aggressively in the mountains at relatively low speed and shifting back and forth from 1st to 2nd and then back to 1st repeatedly.
Other than that, it stays right in the center mark with the top of the needle about 1/3 it's width above the center mark.
Remember, if you are "NOT" using the AC, the fans do not come on till it reaches 226F.
If you ARE using the AC, the fans are on when you are below about 35 MPH.

Sits right at or a needlepoint above middle with the ac on.
ac off, hovers needlepoint above and slowly works its way up to one line above middle, but never higher than that. if i'm crusing, it stays in the middle. traffic light or drive through, it'll come to the first line above center, fans come on, and it comes back to center. knowing how sensitive these engines are to overheating i find myself looking at it more than i want to. however, it's been that way since i've had it. even had the dexcool flushed and refilled by the dealership (i know... i know...) just so i KNEW it didn't have sludge in it. i plan on draining and refilling the dexcool every year like every other caddy i have, so it has no chance of building up and stays fresh.
