I noticed that also, and took my 'Bu in (about eight years ago!) for that.
Turns out the turn on is about 210 by the PCM's computer, and the gauge ... is not really that accurate.
Unless you've added a third-party gauge, then yah, you may need to be worried.
I'd also "burp" the air out to make sure there's no air bubbles in the cooling system (that's what that little plug on the coolant crossover pipe on the 3.1L is for.)
335K miles on original motor and tranny (only motor work 2 x LIM replacement), Monroe SensaTrac struts front and back (new at approx. 300K miles), and Alero discs in back. LS fogs added with custom wiring. HID high beams, HIR low and halogen fogs. Raybestos Pro Grade front rotors and Bendix D747 ceramic pads on front.
Addendum: Rest in peace. Surge tank blew, motor overheated, I think she's lived a long and useful life.
