Have you checked to see if the cooling fans are coming on? Is the coolant level low? Could also be a weak water pump. Does the temperature gauge appear to work normally or do you go from low temp to high temp and then back to low rather quickly? If so, it could be a bad thermostat.

I changed the termostat on my 2005 gmc sierra and now it overheated please help

Thermostat is possibly installed wrong/backwards, defective, or you have a large air bubble in the engine. After you changed the therm you must run the heater ( fan on low) to help purge extra air. Hope this helps. Good Luck
