Thanks everybody, I need to get the nasty pink Dexcool out!

I used the more accessible of the two (top one), and flushed with pure water. Then I added the Prestone Cleaner (it's the one that says "for neglected systems", and you leave it in for 5 or so hours of running time). I ran it for about 5 hours over the course of 3 days, and flushed out for about 15 minutes. I then added some all-makes all-models coolant, and bled the system. It's about as clean as one could hope for, and started out with some nasty looking Dexmud.

One more question, Does this car have a drain plug in the radiator?

I see what looks like a plug/drain in the bottom of the radiator on the driver side.

Havent see one quite like that before.

Anybody remove that or use it to drain the radiator?

Yep, that's the one. Looks sort of like a plastic bolt? It is a bit hard to reach, but is not hard to take out once you do reach it. It makes a bit of a mess as it runs down various wires and supports, so have a large pan. ;-)

Just wanted to thank everybody for the help. Thats a dirty deed done dirt cheap. I even douched the reservoir and made it look new again. :D

I've always just pulled the upper radiator hose, and stuck a hose on full blast in the raditator and let the car run fo a while until I got nothing but clean water,.. Make sure you're watching your temps though.
