There is a black rubber hose located behind the engine that terminates down by the frame just behind the right steering tie rod. It is open ended where it terminates and drips fluid after is has been driven. The fluid looks like water or could be anti-freeze, it is definitely not oil, fuel, brake, PS, or tranny fluid. Is this some kind of overflow for the heat core? It seems too far away from the radiator to be radiator overflow. Can anything be done to stop the dripping?
