1992 GMC Jimmy SLE 4x4 4.3L v6
I recently moved to New Mexico from California and when I got here my Jimmy spring a leek, well more like a gushing torrent of water.
I replace the water pump as i though that was the problem.


While I was down there I then saw the real cause and I have no idea what or where this part goes or how to fix it.
Any help would be greatly appreciated. Thank you

 

That kinda looks like, what I think is called, a "freeze plug". Never had to work on one, but I think chritine has... don't quote me tho lol...


Someone will chime in...
