Hey guys, I have a Z6 engine that needed an intake manifold so I bought one and it appears to be off an automatic D16Z6. I have this extra nipple with a line running to the rear of the manifold - I assume it has something to do with the automatic transmission. Anyway, I have pictures of it here; the nipple / line I am referring to is circled in red. Should I tee this off and connect it with the hose that comes off my water pipe (circled in green?)

 

 

Hey thanks for posting that!

My coolant pipe doesn't have that nipple I highlighted below. It only has that further one closer to the thermostat housing?
