I have an antifreeze leak coming from a hose/pipe on my 96 Disco, it starts at the front of the radiator as a hard piece of about 1/2" pipe with a screw connection. heads down. follows along radiator,takes a bend toward the rear of the vehicle where It has a crimp connector to change it to a flexible hose. for about 6" than another crimp connector that changes to back to the hard pipe . any ideas what this is called? I cant find it on any sites.
