99 blazer radiator flush

ok so i went to the store and got a few jugs of dexcool. also got some prestone stuff called radiator cleaner. There was Rad cleaner, and Rad Flush at the store. the stuff i bought u leave in for 4-6hrs with water, and drive. then you empty it.

the other stuff you just run your truck for 20 minutes and drain out. I figured the stuff i bought woulud be better because its in there longer right? And id rather start off with a CLEANED radiator than a FLUSHED one right?

ok so im going to do this tommorow, i hear there is a flush nipple that slowly drains the old fluid out. (what fun can that be right...slowly! ha) so i am not sure where it is but it is on the radiator right? also heard there is one located on the block.? Someone please let me know about the cleaner vs the flush stuff. id like to konw the difference before i use either!!!
