Is it a browny colour? Most engines corrode when they have mixed coolants in them, so you will have rust and corrosion all down the waterlines. Usually it doesnt budge that easy. Was the 20V sitting in the rain for a while or something? Maybe it built up some surface rust while it was sitting there...
I suggest emptying your entire water system, then stick a hose in the inlet of your engine and turn it on full blast. This is what my friend did even when he had perfect coloured radiator fluid, and bunches and bunches of brown shit came flowing out the outlet... Do it to your radiator too. Then afterwards reconnect all your waterpipes and fill with some really high grade coolant or better yet, genuine red toyota coolant  .
