The only thing you will need is the antifreeze and water which the impala holds a total of 10 quarts but i would say just over a gallon would be all you need because you wont be able to drain it all and you can get a gallon of antifreeze for $10 so maybe a max of $20
Should be on the lower right (passenger) side of the radiator...

I am trying to drain old antifreeze and replace with new and cannot figure out how to remove the radiator plug on my 2001 Chevy impala 3400V6 engine?
Test or replace the sensor in the radiator side tank.
Once a year or when Anti-Freeze is Brown in Color
find your heater hoses and follow them. the flush is usually in an easily accessible location. It is very possible there is not a radiator flush valve. you may need to install one.
Just beneath the lower radiator hose is the drain.
The starter and cillanoid are one. They are located directly under the radiator.
There is a low level sensor in the side of the radiator. They do go bad.
You can flush the block thru the line to the heater core at the firewall. This will flush the heater core also.
