'02 Pontiac Grand Am GT Engine Temp Rise when Idling

After driving with the engine warmed up to normal temp (around 200),
when i get stuck in traffic or at stop lights my engine temp slowly
inches up to the 230-250+ range. I've had a new thermostat installed
and had the coolant flushed, but it still does it. The only thing that
seems to lower the temp (while stuck in traffic or idling) is turning
on the heat full blast.

Does anyone have any ideas what could cause this? Probably an
expensive fix....

Maybe your fan is not coming on. Maybe it just needs a couple drops of
oil or the thermostatic switch is bad.

On the other hand, maybe you need a new engine. Could be....

You had all that done for what again?

Electric cooling fan for radiator not coming on, or rpm too low.

Check to see if your radiator fan is working.
