        Putting the front up doesn't help air trapped in
the raditor and especially not the heater cores. As long as
you open up the raditor bleed bolt you're basicly doing the same
thing except now the resevoir in the rear is the highest thing
in back I should think... But then, my 87 burps itself without
a fuss...
