Has anyone tried, or is there one out there that I haven't found, to put a drain plug on the lower radiator hose? I was thinking about putting a bleed valve down on the bottom hose, like the one that's infrint of the intercooler, just splice it in. Or peak and prestige offer "flush and fill" kits that haveT-fittings with a cap, if there is one the correct size put it in there. Any thoughts, recommendations?
