Celica Forums General Discussion General coolant container

So on my 03 GT for the coolant.. I have the little plastic container thing for coolant.. like everyone else... there are 3 hoses connected to it ( i think 3) one is like a 1 inch piece near the top that is just hanging.. is this the overflow or what? I don't wanna go get the owners manual right now since its almost 2 am and the horn blows loud when i click the button.. thanks

Yah, the hose down the side is the overflow.
