I got a '05 Legacy Wgn a few months ago. I was told that the head gaskets were done...but I have my doubts! It uses some coolant. Not really around town but doing highway speeds. I think I have a internal Head Gasket leak. It doesn't leak anything in the driveway and I don't see any. I'de like to add some of that Subee Stop Leak to see if it takes care of the problem ! I thought it would be SIMPLE ! I did it in my '01 Leg GT Wgn. This '05 has a plastic skirt below. I hoped to be able to feel my way around the lower end of the radiator and figure out were the petcock is ! NO luck ! I thought I might pop the upper hose of and get rid of some fluid that way, don't want the mess ! So what's the easiest way to do this ? Just were is the petcock ? Any hints !?
