Yesterday driving home on the expressway I lost bunch of coolant and obviously overheated. My dash rarely works anymore, so my ScanGage saved my a$$ here. It looks like a failed heater core hose inlet/outlet behind the alternator.
Anyway, my question is one of severity: I was at 250F for no more than 10-15mins, so what should I expect in terms of what-needs-to-be-replaced/repaired?
what should I be on the lookout for in the future assuming it'* an easy fix?
thanks for your advice

recent relevant maintenance: oil change 2 weeks ago, LIM/UIM gaskets one year ago, radiator 2 years ago, new upper hose few months ago. I've also been searching for a small coolant leak, but I'll scratch that one off the list now.
