coolant tank
That little aluminum a/c line on mine coroded through, but the overflow tube is still intact.
The assembly is definitely two pieces, but appears to be glued together. Can't be certain.
But the good news is the aluminum tube just pulls straight out. It goes through a rubber grommet, and the fit is fairly tight. Just pull it up. Twisting it a little helps.
Don't know exactly where to get a replacement, but I'd think either aluminum or copper should be available that can be bent to shape. Dealer probably wants a fortune for it, and all it is is a piece of pipe with a 90 degree bend in the middle.
Just make sure the new piece fits tight into the grommet, or possibly seal it with silicone. Don't want battery acid migrating into your radiator.
