What is this part? I thought I had a bad slave or master cylinder but this part/hose is leaking and i'm thinking it may be a booster for it. Can anyone shed some light? It's the bottom part on this rack which is located on the driver side of the engine bay. Thanks.

The underneath one? It has fluid comign out of it.... and its not water or antifreeze, I don't think. I thought this was contributing to my clutch pedal being soft. lol.

Lower bit is a pump i believe to move coolant around, possibly for standing heating option? works with valves to move coolant to where its needed.

seems to be very common failure item - mine has a code now.
