Make sure the radiatpr is full and coolant overflow reservoir is at the full mark when cold. If it is full, Check the low coolant sensor located in the radiator on the passenger side.
Had similar problem with my 2001 Impala LS I replaced the Coolant level sensor located on the radiator just behind the battery. Go to OE Warehouse.com use AC Delco #10096163 and get it cheap for $26.05 the exact OE sensor in your car now... Auto parts stores are asking $59.

There is a bleed screw on the thermostat housing. Remove the screw with the engine loose. Ounc you have pure coolant and no air you can close off the bleed screw.
To change a thermostat on a 2003 Chevy Impala remove the connectors to the battery, wait for the coolant system to be drained and take out the radiator hose. Remove the thermostat and clean it's component, position the thermostat, put the new gasket on top of the thermostat and put engine oil on the bolts. Attach the radio hose and fill the system with coolant. Put the negative part of the battery cable to the terminal and let the car run for a few minutes before driving.
Check coolant level Could be a bad tenperature sensor or gauge Could be a bad thermostat not opening to allow coolant flow
