Is that even possible? I suppose it could be rust or something else, but it sure looks to be like reddish black, burnt-up radiator fluid. When I drained the radiator this time I let everything flow into a clear one-gallon container so I could look at it (last time I drained it into an oil pan). There were obivously chunks of the same solid gunk floating in the fluid.

Radiator fluid doesn't evaporate and crystalize, does it? What else could this crap floating in there be? I'm not driving it the rest of the week, so that I can screw with it this weekend.

Thanks for any mature and intelligent advice.
Flushing your cooling system is not just cleaning the rad, and piss off about the intelligent and mature advice bullshit, I was trying to help you.

You didn't flush it last time seeing if you did, you wouldn't have crud in your cooling system. You said you topped it off, if you flushed it, then SAY THAT and don't think we are all goign to read your mind.

Replace your rad cap ASAP, it is what is causing the cooling system to failure and allowing air into the cooling system.

You can do all the flushing you can, but it will return to crap all in short order with the stock AC Delco defective rad cap.
