I had time today to remove all the stuff in the hatch area and check the
main reservoir.  It is 4/5 full and warm after a two mile drive at 60
degrees(South Texas Winter).  No fluid in the expansion tank.  Guess I will
fill the expansion, run it and then bleed and see where I lie.  Thanks for
the advice.
