I think you have a power steering leak. it looks like that is the same spot mine ruptured almost 2 months ago but it might be a bit closer to the radiator than mine was - it's hard to tell with only those pics. that fluid would be transmission fluid which is used in the powersteering
Power steering line leak - what is this joint???
If it's the same leak I had then you need parts 4440660021 and 4441260430
