Question: Engine Overheating

Question

my temperature gauge goes up and down when I'm driving.
I also checked the temperature gauge after I parked my car and let the engine running. Then same thing happen. Temperature slowly reached highest point and after several minutes it goes down to normal temperature.

I checked cooling fan, coolant level and color. All of these was fine.

What possibly causes this problem?

Thanks.

  A thermostat that has begun to stick in the closed position will cause the temp to rise then suddenly will open and the temp will drop down to normal, Have you ever had the thermostat changed?
