I went to drain the radiator to flush my system and od the tb bypass and the bleeder screw (not sure if correct terminology, its the thing that drains teh coolant) is ****ed up. Its just a stub. No little "wings" or anything to turn. Any idea on how to get this thing out to drain the radiator and then where to get a replacement one? Thanks guys!

 

While Im at it, im not seein the inlet for the cooling system into the TB. I see an outlet though. Can you even do TB bypass on a 93? Thanks and sorry for the dumb questons.
