Failed bearing or gasket. IT is a wear item, so typical to replace around 100K. Figure a $300 -$600 if you have a shop do it, that's cost of the pump, coolant and maybe some new hoses.

Don't forget the serpentine belt as long as you have it torn down. Do now or later at a much greater labor cost. Use new antifreeze, and if you have a lot of miles on it, ask if a flush of the system/radiator is expensive.
