Coolant flush disaster Options

[The_Chazzman]

Hey, all. I'm trying to flush out my coolant system on my ST204 so I can get all the green junk the previous owner filled it with and replace it with that beautiful red juice. I drained as much of the green stuff as I could, pulled out the thermostat, re-installed the water outlet and proceeded to fill the rad with water. I could hear it making its way through everything until it pretty much all wound up pouring out of the outlet. I would assume this is because there is no stat/gasket in there but, as I can't flush it with them present, what am I supposed to do? Anyone else have this issue? Thanks in advance.

I'm assuming this site has some sort of moderator approval system for new members since my posts seem to not appear until the next day, so I'm sorry if this appears to be a double post. I managed to hack up the old tstat so that the valve is no longer part of it. Its basically just a ring with a gasket on it and its no longer leaking! Sorry I didn't point this out earlier, but the lower hose was attached, it was leaking from the point where the outlet bolts to the water pump housing. I just filled it with water, let it run for a bit with the heater on full blast and am letting it cool off before I dump the water. I'll check for that drain plug that was mentioned earlier and get as much out as possible, then I'm going to run some radiator flush through it, repeat dump, the dump the gasket sealer in there. After that, some Toyota Red and, hopefully, it will be happy until I can pick up my new motor. Then its time to make her pretty again! Thanks for all your comments and advice!
