'05 Malibu Classic - Drain and Fill - How?

[clembrewer]

I've an '05 Malibu classic with the orange stuff in the radiator tank. I bought a gallon of Prestone all makes/all colors extended life premix and I wanted to do a small (1 gal) drain/fill. I try to do this every year on my cars.

Anyway, I can't figure out how to drain fluid from the radiator. There is no little spigot that I can find on one side or the other. There was a little white plastic screw that I could turn with a 1/4" square drive, but that didn't seem to accomplish anything.

How do I do this?

Dunno, but you really don't need to do it yet unless you are getting close to 100k miles. With Dex Cool I actually think mixing it is worse than just using up the original fill until it's recommended to change it. Just an opinion, we have a 2004 M Maxx and I haven't even considered doing a chnage yet, the fluid is still prestine, I just added some RMI 25 and that's it. I'll check mine tommorow and see if i can't figure it out, I think we have the same engine?
