Question Help Save My Opti

Hey Guys I noticed today I was losing some coolant so I climbed under there to check it out, and noticed There is a hole in the very bottom and directly in the center of my water pump. The hole appears to be threaded but im not sure. I have coolant leaking out of this hole and getting dangerously close to my opti. What is supposed to go in there or what can i put in there to stop it?

That is what's referred to as the "weep hole". It is not threaded, and nothing goes in it.

When coolant leaks out of the hole, that is indicative of faulty seals within the waterpump housing. I'm afraid you're going to have to replace your waterpump.

Well if the weep hole is leaking it's time for a new pump.
