Hi
My 2004 Pontiac Grand Prix 90k has started to run on the hot side (hotter than I'm used to) while sitting stopped in traffic. It is very hot here. It does not get to the red but on the gauge shown here I'm getting close. About 5/8 with 3/4 being red. Normally I don't run above 7/16 maybe 1/2 at a red light and then it drops to 5/16. Now it's only dropping to 1/2 when I start running although it seenms to be a bit erratic. Drops to 1/2-7/16 and quickly pops back to 9/16, then back to 1/2 at a steady 50 mph.

expected it to be low on fluid but it was full. Both fans run. No anti freeze in the oil.
It did this 6 months ago after I bought the car. I added fluid and its been fine since till now.
Any thoughts?
