Remove the two clamps, spray a little penetrating fluid in behind the rubber and kinda work and twist them off the core.

All I did was tighten the clamp on the left hose coming off the heater core.

Hallelujah you got a tester going! Now leave it pumped up overnight. (Or at least several hours.)
I had the same clamp that needed tightened one of the last times I used the tester. When the car was running, the heat and airflow hid the drip. But cold pressure testing made it obvious.

Cut and peel is easier on the heater core, unless your spouse does not trust you with sharp tools any more.

Its been 24 hours and no leaks so all it was is the left heater core hose clamp was loose.
