to drain look near the bottom of the radiator there is a petcock turn it with the engine cold, you will want a pan under there to catch the old stuff, and dispose of properly. been so long since I did an f body I can't remember where the thing is though, also pull the cap off

Also make sure to drain the block as well, I didn't when I changed my antifreeze (when I changed my water pump) and my new antifreeze looks like the same old muddy junk.

a good idea is to unplug the drain plug then run a hose into the radiator cap then just flush the system.

I fill the rad with plain water and run it for a few minutes then drain again, mix may lean out a bit, but you can check it while filling, or have a flush done, just draining the block leaves alot of stuff
