1999 Chevy Monte Carlo Car Overheats, Oil Change light come

About 3 weeks ago, I was driving from the supermarket and I looked down at my panel and the temperature gauge needle was sitting about 3/4 of the way toward the Hot indicator. A couple of seconds later my Check Oil light and Coolant Light came on, the temperature gauge swung all the way over to hot, and I pulled into a parking lot right as the car stalled.

I shut the engine off, got out and raised the hood. There was no smoking or steam coming from the car. I checked the coolant and it looked fine. I checked the oil and it was at the full line. So it wasn't low. I waited about ten minutes, started up the car and it started up without a problem. The Oil and Coolant lights came on again, and the temp gauge read normal. I started driving back home, carefully, and the temperature gauge would bounce from the bottom temperature to the top and hang around near the top without hitting "Hot" again.

Last night I started up my car just to see it's reaction. The Check Oil/Oil Change light comes on and stays on for about 3 minutes. I haven't driven it anywhere to test the temperature gauge, but again, no steam or boiling sounds coming from the car or anything. If it helps, the weather that day it overheated and stalled was very cool weather. Upper 40's, Low 50's. I don't know why it overheated.

I thought maybe the oil needed changed, but I've only driven 1100 miles so far since my last oil change.

Your help would be greatly appreciated!

Check your owners manual for oil change light reset procedure.

But I would have the cooling system pressure tested and change the thermostat. This would be a good starting point.

Could be a bad sensor/sending unit/gauge, but you do not want the engine to overheat, which can cause head damage and many other problems.
