    I need to flush out my entire cooling system, I have always just used the garden hose in the raditor for about 30-45 min. but the stuff that is in there right now I don't think will come out without a little help, So what do you guys use? /forums/images/graemlins/1zhelp.gif

    drain whatevers in there, and fill it up with water and powder cascade dishwasher detergent. Run it for a few hours drain that and refill with new antifreeze.

    Used vinegar before, not sure that it works any better than anything else, but it did pull a lot of stuff out.

    Radiator was still garbage, don't think any of the stuff you can buy will remove all the scale from the cores, and you can't see about 50% of the cores, so even if the top looks good, the bottom is probably not in as good a shape.
