clean radiator where the fan pulls air thru the radiator

is that with the a/c on? make sure the fans are working , they should kick on as soon as the engine reaches 180-195 or immediately with the a/c on.

I would also consider running a lower temperature thermostat. I ran a 160 in my camero for the same reasons you are seeing. Cleaning the radidator will help increase the flow and the cooling. Have you checked the antifreeze, Antifreeze will tend to be less effective as it ages. Check that the fans work, and see if you can make them turn on at a lower temperature.

The radiator fans come on only when the temperature reaches about 225 unless the AC is on, in which case the fans run all the time. When you are sitting in traffic, there is not enough air flowing through the radiator, so when the temperature starts to rise, the fans are supposed to kick on. This will bring the temps back down to about 210. (these numbers are approximate) Under normal conditions, if your thermostat and radiator are all functioning properly, the temps should be about 195 when moving, even on hot days. First, make sure there is no debris in the front radiator area way up in there. You will need to jack up the car to look and reach. Then make sure the fans are working, and make sure the fan switches are working at the appropriate temps and conditions. Last thing is that your thermostat is good and your radiator is not clogged and plugged up with old antifreeze. I don't remember if that year still had green antifreeze or the newer yellow stuff. If its the yellow stuff, it may very well have turned brown and clogged up your radiator at which point it may need more than a good flush.
