can't find what is overheating Your S series Saturn? you've checked the obvious but still overheats. Lift the car so you can get under the front end (use jack stands if your on the ground) remove the plastic panel  on your s series saturtn so you can see the radiator and condenser.  look for plastic bags, leaves and heavy debris. I have even on several occasions found what i can best describe as a "lint blanket" because it looks just like what You find in the screen of your drier between the condenser and radiator. don't ask what it was made of but it looked  just like lint. that is not as common as plastic grocery bags though. while you are there make yourself a long air nozzle a piece of metal brake or fuel line with a few small holes drilled so you can run it up between the two does a nice job of blowing out in both directions. You'll be suprised the dust cloud and debris you find.
