    Re: Radiator Drain Plug

    Hey Aj, what's the easiest way to see/get to it? Engine bay or underneath truck? Is it hard to get to? The next time I attempt the flush (Spring Break), I want to be able to find it with a blindfold on.

    Re: Radiator Drain Plug

    actually, i think the easiest way, is to just undo the lower radiator hose, ie, the hose going INTO engine... the only way i see u gettin to either of these holes, is removing the fan shrouds, upper and lower... i know when i drained mine, the fan shrouds were out, so it was wide open, tons of space...
    i don't have a stock radiator in anymore, so i cannot tell u the best way to access it..sorry bro...

    maybe some other smartarses here can chime in...ie K5Chris....LOL

    Re: Radiator Drain Plug

    I agree w/ doing the hose trick too. I flushed the sytem on Ted's '99 Tahoe (4wd) when i did the intake gaskets and because of the 4wd stuff in the engine compartment it was a mofo to get to the petco(k.

    If you undo the pet**** the fluid runs all over the frame and it is tough to control. The hose trick is right on.

    if you can even get the petc*ck loose, they tend to break easily, i would just pull the hose off too.
