1993 Chrysler Cirrus My car over heats

Here are some other things that happen. The radiator could be clogged, the fan which turns on electrically may not be turning on, you may have poor circulation from your water pump. Or the head gasket may have a slight leak. I used to have a meat thermometer because I left mine in a car and used my wife's. It was the same thing with a different backround. The fan, with the temperature gage in the radiator should be coming on no later than 205 degrees F. It gets hot but this is how you test it and if you drain the radiator down a bit, you can use a light and watch the circulation and pressure. A pressure test is next. If you take the cap off first you can watch the thermostat open, it's quite exciting. This whole test all takes around an hour and is how you can get a great idea how the overall condition of the cars cooling system is. Or you can turn the heat on and use your hand.
I hope you understand a little better. For 30 bucks you can buy a laser tester and use that to test everything and get dinner on the table medium well. They work fantastic for anything, except your body temperature.
