Thats completely true. I guess I probably would do it the easiest way possible in 10 degree weather too. My brain just doesn't think that way...haha.

That being said, if you're going to mix coolants, even if compatible, I would DENINITELY do a flush in the spring when things warm up a bit. :)

ditto. As I've said :P

I completely agree. A yearly flush should be on everyone's agenda already, since Dex-Cool is the way it is.

Agreed.
Even though dexcool is supposed to last for five years, it seems to gunk up pretty damn fast.
Especially if it ever has a chance to get exposed to air.

-Riggs.
