I would check the short intermediate hose between the head and the pump. I'll bet it's spraying coolant down towards the back of the pump. If that isn't it, then the o-ring between the pump and the block is leaking..or,,the impeller shaft seal is leaking and the coolant is running out of the weep hole at the base of the pump.. I'll put my money on the short intermediate hose betwen the head and the pump..
