My question is, as the rust comes loose and travels will it clog something along the way? I would think that I probably should run it idle and flush the radiator and repeat the process a few times until I'm confident enough that most of that rust was flushed out. It doesn't look like any coolant has been through there in awhile. Do you think that the rust may get trapped in the radiator?
