Could be a thermostat, or could be your fan clutch since it heats up when you're at a stop. Those two comes to mind first.

Fan clutch is most likely. Get a small section of rolled up newspaper and try to stop the fan with it when you're stopped and the temp is goin up. If it shreds the paper it's fine, if you can slow/stop the fan the clutch is shot.

Also, could be an air pocket. Try bleeding the system.

It would usually be a better idea to help the guy so the thread would die quicker instead of posting stuff like that.
