I agree, I usually don't do that, but I can not find the leak and also, I don't even know if it was a hose or not because there are only 3 or 4 hoses at the front of the engine that carry water and every single one of them was dry. So was the radiator and so was the water pump and the belt tensioner. The only fluid I saw was either in a puddle on the ground or dripping off the bottom portion of my bumper. I have actually used the bars stop leak in the past and I usually like to keep it circulating in my system and it keeps all the seals very pliable and keeps everything lubed up and corrosion free. The leak has stopped hough since adding the bars to the system so maybe it was a small hole somewhere. Eventually it will have to show itself again, but probably no time soon.
