I've had my 2002 Saturn for about 7 years now and I'm the second owner (only 7,000 miles on it when I got it).
There was a problem with the AC clutch which I had replaced about two years ago, but then about a year ago the same problem occurred. Not having the $700 to get it fixed, I've been driving "as-is" with no problems. I'm not sure if that's related to what I'm about to tell you.
About 3 weeks ago, my "Low Coolant" light has been coming on every time I start my car. It eventually got to the point where I was putting antifreeze and/or water in every day. I took it in to a mechanic and they couldn't find a leak, so they put some stop leak in it and said to come back if the problem continued. It did. The light kept coming on and I had to keep filling it with water. A few days later I was on the highway and my car began to overheat, by the time I got off an exit and to a gas station it was red lining. I waited for it to cool down and then filled it back up with water. 3 miles down the highway and it overheated again. Bone dry. I filled it up again & dropped it off at the mechanic.
They said that the water would overheat & bubble out of the reservoir. They replaced the water pump and returned it. It was fine for a day, but then after starting the car, the coolant light came on, and when I stopped, antifreeze was dripping out.
Back to the mechanic, they replaced the thermostat and radiator and I got it back.
On the way to work today, it overheated again.
What else could the problem be?
