Ok, so...Before my car was leaking antifreeze which most of it seemed to be dripping from the water pump pulley, seeing how the radiator fluid line above it wasn't dripping or leaking anything I changed out the water pump and the lower hose. I ran my car till about normal temperature, after the water pump change, and then shut the engine off and waited for any dripping but didn't get any...Now, when I start up my car this morning it says that I need radiator fluid and there is a small puddle on the passenger side. Could my resevoir itself be leaking? Or perhaps that lil petcock on the side of the engine (which I have no clue where it's at) that keeps the fluid in? Any ideas?
