Aaron AND LRG - Thanks for the reply. The fluid is hydraulic, because I put 1 (blue) container of it into the green reservoir, started the engine and it immediately dumped it out onto the ground, the puddle being LARGE enough - volume of the blue container of the MB fluid. Nothing else is leaking THAT MUCH. I was in the back of the car looking at the valve that controls the level, when this happened. It was only when I went to the front of the car when I saw it dripping in the major way - clear in "color" on the black top driveway. And the reservoir level was at the bottom. I'm hoping (of course that this leak is at some sort of junction or connection in these metal lines - if not, can the lines be spliced or patched in some way? Or is this just wishful thinking? Once this leak is fixed, how can the system be flushed out? Thanks again.
