Hey fellas, I'm sure this is a silly question but ... I just replaced my radiator (actually just put my engine back in) and when I took it out for a test run and came back, the radiator coolant/anti-freeze was spilling out from the little opening near the radiator cap. My questions is:

Should there be a hose to connect that lil spout to the overflow tank? If so, what is it call or can I make one?
