hello im new to the forum w/ a question. on the rear of the lower intake by the firewall there is a 3/4" fitting that a hose connects to. when i fill up my radiator fluid pours out this fitting. what does it go to? and what is it. i have the alldata program for my car but cant find it. oh yeah its a 91 gt 5.0.

 

pictures usually work wonders

 

i posted one but i can't get to it w/ a camera that is why i explained where it is.
