Is this healthy looking coolant?
Maybe I'm paranoid. I smelled coolant on the drive home, popped the hood and looked around with a flashlight for leaks, found none, smell seemed to be coming from the front of the bay. Got underneath after carefully popping the cap and saw slight moisture on the drain plug, (Godspeed rad FWIW, it's worth noting the rubber seal on the drain plug is very cracked and dry) and drained the coolant into a bucket.
Healthy looking? This isn't "chocolate milk" right?

Looks like a little bit of cross-contamination from products of combustion. It's an old car with lots of boosted miles, and **** happens. Nothing to be concerned with.
Dump the coolant, pull the t-stat out (try real hard to not break the fan switch in the process), and stuff a garden hose into the radiator side of the lower rad hose. Turn the hose on and run the engine. It will probably take a couple of minutes until clear water runs out of the radiator. Refill with your favorite blend of purified water and antifreeze, and replace the t-stat. Will most likely require a new t-stat gasket.

Thanks all. I replaced the coolant and put a new, better seal on the drain plug (the old one was pretty sorry looking). I'm going out of town for a couple days but when I get back I'll test to see if I still smell coolant. Based on the condition of the old seal that ought to have done it. Will flush thoroughly before heading to Texas.

Okay, so the seal might not have been "better", lol.
It's now leaking worse than before. I really need to seal this up since I leave for Texas on Monday. The problem I'm having with the seal I used is that it's round (like a donut) and is too spongy to allow me to tighten the drain bolt properly. I probably need to use a flat-style seal like before, but don't know where to begin looking short of Home Depot and whatnot. Help!!!

Look in the oil drain plug section at the auto parts store and get a flat rubber gasket and stop playing with it. Just spend a dollar on the right part and stop worrying with making the wrong part work. You want it to be reliable right?
Good luck.
Here's a value pack for $2.89. Use the big blue one.

Sixshooter, those are WAY too big, I ended up finding the right sized washer after the second auto parts store clerk recommended I get a fiber washer from home depot. So, now it's that fiber washer and a good bit of RTV.
