Not sure how you made out, but I would try flushing from the engine back to the water pump. The lower radiator hose would also be a "must check".

The primary passage from the water pump is into the cylinder head. You can pull the engine coolant temperature sensor (at the back of the head, below #6 intake port) and flush back from there. I haven't checked, but imagine this is a pita to get to.
