Buy the following:
NOTE - If you can find them, the two part acid flush and neutralizer kits work much better than the Prestone Cleaner. Substitute for the Prestone Cleaner and follow the instructions on the package.

Drain the antifreeze from the system.
Install the "T" from the Flush 'N Fill kit and follow the directions that came with it.
Disconnect the water hose, close all the drains, add the Prestone Cleaner, fill with water, run the engine 3-6 hours (you can leave it in for a few days if neccessary), drain the system.
Connect your water hose to the Flush 'N Fill "T" and flush one more time. Drain.
Fill the system with a 50/50 mix* of antifreeze and distilled water. Continue to fill the system over the next few days as the air is worked out of the system.
*When you do your final drain and fill....not all the water will come out so to get the proper 50/50 mix you should add the right amount of straight antifreeze then top off with the distilled water.

To open the petcock on the radiator of a 2002 Chevrolet S10 with a 4.3L engine, follow these steps: Safety First Ensure the engine is cool before attempting to work on the radiator to avoid burns from hot coolant. Locate the Petcock The petcock is usually located at the bottom of the radiator on one side. It may look like a small plastic or brass valve. Prepare a Container Place a container or drain pan underneath the petcock to catch any coolant that may drain out. Open the Petcock If it’s a Twist Type: Turn the petcock counterclockwise to open it. Be careful not to over-tighten it when closing. If it’s a Pull Type: Pull the lever or knob out to open it. Drain the Coolant Allow the coolant to drain into the container. Open the radiator cap (if necessary) to allow air in, which helps the coolant drain more freely. Close the Petcock Once you’ve drained the coolant, close the petcock by turning it clockwise or pushing it back in, ensuring it’s secure to prevent leaks. Additional Tips: If the petcock is difficult to turn, you can use pliers, but be careful not to damage it. If the petcock is corroded or damaged, consider replacing it to prevent leaks in the future. Always dispose of coolant properly, as it can be harmful to the environment and pets.

no GM changed the cases
your radiator is plugged or possibly a bad head gasket, would check radiator first
Assuming you are asking about the radiator coolant drain, it should be on the passenger side under the lower radiator hose. It should take a 1/4" square drive to open it.
Yes
with a dipstick
no the lights mounting area and wiring harness are different. I have the opposite problem a 2000 s10 and bought a 96 radator support
Check to see if the area between the radiator and the ac condensor is plugged up with whatever. It may be hard to see without taking the radiator out but it could be loaded with leaves or what have you.
