The 2000-2005 Chevrolet Impala only came with a 3.4 and 3.8 V6 (6 cylinder) engines. Are you sure that you don't have a Malibu instead? at the emd of the upper rad hose you will find the thermostat housing. Take the 2 bolts out and remove it. When reinstalling it make sure the spring on the thermostat goes toward the engine.
Show me the picture of it
Drain the radiator down 1/2 way into a container. Remove the top radiator hose from the engine end. The housing is where the thermostat is located. Remove the 2 bolts and the housing. Remove the thermostat and clean the surfaces and install the thermostat.

Any Auto Parts store can tell you the correct temperature thermostat for your Impala. Probably it requires a 195 degree thermostat. One thing for sure is no thermostat is not what you want. Running without a thermostat, will cause the engine to not reach full operating temperature. The engine will not perform to peak efficiency at below normal operating temperature. Normally that is around 220-230 Degrees. Your engine is computer controlled and the computer bases fuel/air mixture and timing on the engine temperature. Install the correct thermostat.
On a 3.4 the thermostat is on the far right side while standing in front of the vehicle, below the intake. You will need to remove the exhaust crossover and some coolant tubing from the top of the engine to get to it. Hope this helps...
