Fix the heater core ASAP and hook it up again but PLEASE get rid of those rubber caps. In an ironically similar situation, I blew the end off from one of those rubber caps & the resulting mess was weeks of clean-up work from slimy coolant over an entire carefully detailed engine compartment! Never again!!!
