the trick to the hidden heater hose is this.
once you've abused it off, (cut it with a stanly, twisted the thing with slip joints, whatever)
clean up the surfaces of the fittings, wipe them and the inside of the hose with concentrated coolant. slide the clamps onto the fittings, slide the hose up onto the smaller fitting, place the clamp in position but dont tighten it, push it all the way on and then some, lever the large end onto its fitting and the wiggle it back.
put the clamps on.
