Just found it. PCV hose pipe.

Does anyone know what this steel hose is called? I've searched the forum and online, but can't find any information.

It sits right above the lower radiator tube, and has a pin hole in it.

Ok, I am officially stumped. I have a 98 S70 Na and am trying to remove the water pump. I've removed all 7 bolts, but the pump housing will not budge! I've tried to remove it with a pry bar, but the darn thing acts like it is welded to the block.

Any thoughts?
