I have a freeze plug that's either blown out or most of way out. I pour water into the thing and it just runs right out like it's wide open. I can see it running out, but I can't quite see the source. Looking at it from the front, it's just to the right of the water pump. Maybe just behind the power steering pump. What's the best way to get to that? I have a Haynes manual, but it doesn't mention anything about freeze or frost plugs or expansion plugs, core plugs, etc. Is there a diagram or something somewhere that shows the different freeze plug locations?
