ItsMeDc--

Anything but Dexcool.

Me, being a genius, failed to pop the radiator cap when buying my GTP. When I finally did get around to it, it was completely gunked.

Me, being a genius, flushed, and refilled with Dexcool because that's what all the stickers inside the hood told me to do.

Only to have it re-gunk in less than a thousand miles. The reserve tank was unsalvageable, and I'm sure there's a lot of gunk fused in the bottom of the radiator that I'll never get out. I'll have to replace the rad eventually.

I stuck a garden hose in one end of the radiator, pulled the drain plug at the other end, flushed like crazy while I went up to Sonic to get a couple burgers, came back a couple hours later, refilled with conventional green, and haven't looked back. I will never buy any General Motors car with Dexcool in it, ever again - at the very least, it will be the first thing I fix when I do buy it.
