Luis, You should be able to trace back where the coolant is coming from. I imagine if it's not obvious, it's coming from behind the timing belt covers so I'd take the drive belts off and pull the middle and loosen or pull the upper cover; loosen the lower one and see where the coolant is coming from. You might have just blown one of the pump gaskets. I've seen that a few times. Did the pump you used have the paper gaskets? I don't mind aftermarket pumps, but I try to use the metal mazda gaskets. Let's see, if it's the water pump, could be leaking from the rear main pump seal (to the block, main gasket), the front shaft seal (pump needs replaced), the water pump outlet (where the other gasket goes) or the oring on the water pipe.
