You may be circulating rust and debris that have come loose from water passages as you drive. The flush may have loosened some/all the rust at the bottom of the block that was stuck for years. These can clog the radiator tubes and cause over heating. I had this happen to me after I flushed a system in my brothers Galaxie. We loosened all the garbage and it continued to come loose and repeatedly clog the radiator. We installed a Gano Filter and it cured the problem; after about 6 months the filter was not trapping any more debris so we took it out.

Just an idea,

Joe
