I'm only acquainted with car inspection in Pa.and Md. but on TV I saw a
woman who bougght a used car, found out that the heater core was
leaking, and didn't take it for inspection until after she fixed the
heater.

Is there any state where that would cause a car to fail inspection?
Every single one if it causes (and it usually will) an antifreeze fog
on the inside of the windscreen when the defroster/defogger is used.
