I need to change the hose on the right in the pic on a 2003 Jeep Liberty under the overflow tank. I am not sure what the part is called it is hooked to the heater core and split open. I am also not sure if you have to order the whole assembly or if I can just change the hose, as it has aluminum on the end of it. I took this screenshot from a video I found on the net. Any help would be appreciated. Thanks.
