Repair heater hose from bonded heater hose assembly

Thanxs pushrod, how do I get this metal piece unbonded from the rubber and steel part without damaging the steel portion that goes into the manifold ??

Dremel tool with cut off wheel - or equivalent - cut only the outer metal jacket in two places - 180° apart. That’s actually a crimped on clamp - rubber hose is inside that metal jacket - ok if hose gets cut - just try not to damage the ‘inner’ portion of the fitting that the hose is connected to. New hose can be clamped to fitting with conventional hose clamp. Good luck!

Sounds easy enough! This hose does carry coolant correct?? My original issue is my vehicle is overheating, I have to keep adding fluid to the radiator bc it's dry but the reservoir is full. I noticed liquid leaking from this hose. So it does have to be replace regardless. Just hoping it solves the issue. I just changed the radiator and thermostat so definitely trying to figure this out ASAP
