please HELP

[hulk]

does anyone know what the aluminum tube in the back of the block is called?i keep blowing the o ring out and i just wanna order a new one i think its worn out were the o ring goes.

where on the "block" is it? does it have hard lines,rubber hoses,pressure fittings? have you tried tracing the lines to see what it connect's to?, we need abit more info than a tube on the block.

its a part of the cooling system cuz when it blows out antifreeze leaks it seems to either connect or is right next to the thermostat housing

sure it's not your water pump? it's on the right side of the block just below the fuel rail kinda hidden by the plastic air intake, as far as i can remember without going outside and looking there are no cooling system hard lines on the rear of the engine.
realy ya need to take a picture and post it, or a link to it, on imageshack if you can do that i'm sure one of use will know exactly what you need.
