[R_I_PT]

sorry for another thread. But I tried logging in many times and could not.

Does anyone know what the gold small cylindar at close to the radiator cap is?

I know I am describing it horribly....

It's below the radiator cap, and it is a 3 inch (maybe) thing that sticks out. There is a gold thing that sticks out but it almost looks like there should be a hose connected to it.

Can anyone tell me if there should be something on it, or what it is?
