I'd make sure that the water pump is functioning properly before running
it too much.  Make sure the belt to the water pump is ok.  Otherwise is
probably air is system as mentioned previously.
Good Luck,
Chris

Harold, sounds like you have a lot of air in your coolant system and not
enough coolant.  If the cooling system is incorrectly bled, the
remaining
air will force more coolant out into the overflow container.  The
archives
is full of postings about bleeding the cooling system.
