I was under the car and i can not seem to find it to i just have to pull the bottom hose off to flush it out and should i use dex cool like it says or regular anti because some say the dex messes with ur gaskets!

Try looking for a plastic drain plug directly underneath the radiator. I found this on a 98 Oldsmobile I worked on, they put it on the bottom of the radiator. Should be on the drivers side.

Bottom left corner,driver side.
pull back the plastic air dam looking thing.
You'll see a small hole that is the peg on the radiator where it fits in to mount.
Reach above it and you'll feel it/see it.
The fluid will actually drain through the mount peg-threw me off when I flushed my rad a few weeks ago.
Mine's an '04 LS,but should be the same.
