If it is coming out of the weep hole, you need a new water pump... That hole is used to bypass water out of the pump in case the seals on the bearings of the pumps go out... Best thing to do is go to Advance or any parts house and pick you one up for 25 bucks or so... Good luck

Just a small hole in the housing to drain fluid. They are easy to find if you look at one.

Even though this isn't a mustang pump, you can see the hole here by the white dot.

its a little hole in the bottom of the pump when the bearing or the seal goes the coolant starts dripping out of it best way to tell if the pump is going

my edelbrock victor water pump leaked right after I put it in, turns out the heads of the 2 bolts they use to hold on the backing plate are too wide, had to grind a 1/8 inch off them

but a new pump isnt expensive and will give you a piece of mind.
