My 97 runs very hot, it will stay at 225-235 while moving, but as soon as I stop and let it idle it starts creeping up to 250+. Its always done that though, despite coolant flushes, radiator change, cleaning leaves out of the grill area, etc. Mine has 155k miles now and still runs strong. It even does this when its relatively cold outside, like just last week it did it at 50 deg F.
Since its not my only car, I tend to avoid driving it in traffic, mainly to avoid overheating and to spare the clutch that torture. I think its pretty normal. The only way to make it run cooler while idling is to somehow get more air to the radiator (which isn't easy with the retarded way the front end is designed) or add higher flow rate fans, which I have never seen done.
You could try adding that coolant additive they sell at autozone, I dont think it does much, but even just a few less degrees will help. A performance radiator may be doable as well, but then again, that wont change how much air is getting to your radiator to begin with. So idk. It hasnt seemed to hurt mine though after 100k+ miles of it doing that.
