    Changing fuel injectors on L36

    Im about to order six acdelco injectors to be on the safe side.
    For what I understand, its plug and play ones you get of the fuelrail..

    Anything else I need to change in the meantime? Additional seals, o-rings?

    Thanks,
    Marcus

    Hi m8, are the o-rings and injector seals included with new ones? If not its recommended that U change those too Their change is quite simple
    before you rip off old ones just clean the injector area with pressurized air.

    I’m not really sure what comes with the new acdelco injectors.

    Maybe someone can shed some light on the subject?

    disconnect plug wires from coils to move aside
    disconnect injector wiring
    unbolt fuel rail
    pop out fuel rail and injectors
    drain fuel rail via schrader value
    remove c clips
    pop out injectors

    There are o-rings on both ends of the injector. Hopefully new ones come on the new injectors. Otherwise they can be reused, just make sure they aren't damaged. Also it is possible for the o-ring to stick in the fuel rail when you pop out the injector. I don't recall, but you may have to unbolt the coil base to move it out of the way too.

    As long as you aren't pulling the rail out, it is that easy.

    What's up Keith.

    It's doable, but it's a very very tight fit. Hope you got small hands

    basically.... You definitely don't need to disconnect the feed and return lines. If you need more room to work with you can wiggle the fuel rail out from behind the intake and over the alternator. Then you can just flip it over and do whatever you need to do.
