Motor leaking Coolant

I just noticed a puddle under my truck (04.5, 5.9L) and tracked it to a circular indent between the exhaust ports. I have no idea what this particular part is but I know that coolant seeping from my motor cannot be good. Coolant level in the radiator is full, no signs of coolant in the oil either, is anyone familiar with this? I've got a picture that I'll get uploaded as soon as I figure out how...any help on that little trick would also be appreciated...

Just showed my dad and was told that it's a freeze plug. No matter how old I get dad can always drop some knowledge. So, anyone know what it takes to make a freeze plug stop leaking?

Rip the old one out and pound in a new one. Don't drill it and get shavings in your engine. You'll also have to drain the coolant down below the level of the plug or you'll get wet. I used to just smack them with a screwdriver and get them twisted or poke through, then rip them out. Clean the hole up a bit and tap the new one in.

Put some brown Permatex sealant around the edge of the new one before you install it. Use sandpaper if necessary and make sure the sealing surface is cleaned down to shiny bare metal.

Thanks for the tips guys, got a new plug tapped in...exhaust manifold made it a bit difficult, pretty sure it's not perfectly straight in there. Is it going to just blow right back out when I get it refilled and running?
