Noticed over the past couple days a very slow leak of some liquid coming from the rear

It's more towards the drivers side of the engine, it's very slow and almost seems clear or sometimes really light brown

Going to take it in next tuesday but wanted to get an idea of what i'm in for

thanks

 

photo one looks like a fitting for a coolant hose to me.
but photo four makes it look like the liquid is actually coming from above that coolant fitting. I can't tell what that dark gray circular object is in the photo.
sorry I can't offer more.

 

It's one of the pulleys (fourth pic on left?)

 

Could it possibly be your AC condenser purging the access moisture. It has been hot in your area lately.

 

That was my first thought, but that pic above is after that car has been sitting for 14 hrs

I checked last night when i got home (in 40deg C weather) and it was fine, no leak. But i guess overnight it came back
