    What does the egr circuit have to do with getting new tires?

    It will keep the tires from moving, because the cooler will clog and create back pressure
    and blow the head gasket.

    It's NOT as hard of a task as many make it out to be. Just a little time consuming the first
    time you do it.

    I'm not understanding the connections between tire changes and the egr coolant clogging and causing the head gasket to blow. What exactly will keep the tires from moving? Or, why will the coolant clog the valve? Does it have to new with new coolant added by the mechanic? Is this a routine cleaning that is to be done when tires are changed?

    There's no (non-humorous) connection to the EGR (Exhaust Gas Recirculation). Anyway, more info:

    :(
    Okay... If the egr cooler is clogged.
    It will create excessive back pressure, possibly causing damage to the head gasket.
    If it's not cleaned(cooler), and the head gasket fails, it will cause the engine to stop working.
    The engine spins the generators that charge the hybrid battery, if you drive the car on battery only,
    the battery will discharge to the point it will not start the engine.
    Eventually, the car will have not power to move, thus, the wheels won't turn.

    Bottom line, Clean the EGR System sooner rather than later.

    I'm happy to have learned about this, although surprised to have learned about it in a thread pertaining to changing tires.

    in another recent tire thread, it turned into someone bringing up buying a 2021 prime and jumping a jeep. Then morphed into license plate issuance and insurance.

    Good to hear you got new tires. I wonder is the EGR and such still a problem on Gen4s? Will you look at that! Mendel has a new photo! I still don't have one. :D
