    NOT usually! MOdern cars nearly ALWAYS use the BEST BOSCH injectors around, as fuel economy rises each year and ENGIEN QUALTIY is improved using MORE PRECISE injectors and engine parts to make the government HAPPY! The areas more concerning are OIL QUALITY ( nearly ALL cars require FULLY SYNTHETIC OIL to protect gaskets seals and exhaust systems) Keep engien CLEAN using GUNK ORANGE ORIGINAL ENGIEN CLEANER at a DIY car wash! This keeps RADIATORS and AC condenser in best shape. also dissipating HEAT most evenly, etc! BYE NOW!

    "over heated due to coolant leak -->etc<---"???

    What is the "etc"? I know it means et cetra! What else was wrong that you typed 'etc'???

    Anyway. Coolant can and will damage injector seals but won't damage the injectors them selves. Fuel can damage coolant seals. If you had fuel and coolant mix both the injector seals (which, yes, are usually o-rings and a washer at the bottom of them sometimes) and any coolant seals should probably be replaced. The injectors them selves should be ok unless they were worn or malfunctioning anyway and need replaced.

    Fix the overheating and try to start.  Car starts and runs good, the injectors are good.  Anything else is just guessing.

    The injectors for most cars are in the intake manifold. It would take an extreme over heating to damage those O-rings. But some cars have direct injection, but those injectors have more then rubber O-rings to seal the system.

    While not impossible, it is highly unlikely.

    Probably not as the fuel going through the injectors will keep them cool.

    A guess is probably, and perhaps some other stuff is damaged.  That is all that can be guessed from "Car engine over heated" and no other details.
