help something leaking

[fpvguy]

Hello all
2008 king cab d40 navara
I'm not a very mechanical minded person so please bear with me,
Just got from work and notice something leaking from under the the Navara coming from driver side close to the bottom of the engine but looks like power steering area I think cause of were the area is and my bottle keeps going down while the engine is running,
Any ideas?
Thanks

Yeah, looks like the power steering but hard to tell from the photos. That nut in the first photo looks like it's loose.

Yeah, that's what I thought too. I would put a spanner on it and nip it up it may just be that...
