Once or twice a month overheats real quickly, you can watch the gauge move to hot in about a minute or two. I turn off the car wait a few minutes then restart the car the temp returns to normal. It will run without overheating for a week or two then the same happens again.

Replace the thermostat and use a better grade, not the cheaper one, they are a better 1 time fix.
