    Flushing the Cooling System

    47K, figured it's time. Have air in the system also, it needs a burp.
    Do we have a petcock on the bottom of the radiator, or is disconnecting the lower hose the way to go?
    I'm using the Prestone flush kit that connects to the heater hose.
    Any comments are appreciated.
    Thanks,
    Jim?

    I'd disconnect the lower hose, drains faster.

    There's a plastic petcock on the driver's side of the rad, it'll take a while to drain but makes minimal mess. It'll only drain the rad, maybe a bit more than a gallon.
