Parts online

I have a small coolant leak somewhere in front of the thermostat. I believe it is a flexible hose that is in front of the thermostat and goes to the side under and in back of the battery.
I been trying to find Nissan parts online but none of them have diagrams so I can actually see where the hose goes. A lot of them don't even have pictures of hoses, so I can confirm the shape.

Any site that show diagrams where I can get an idea what I need?

I finally found a decent starting place.
Attached is a diagram I found on a Nissan parts place online.
The area circled in blue is where the coolant is leaking. It looks like mist spraying lightly on top of the transmission. Just s light blue coat.(Note, I had to add about 2 cups of coolant).
Will check level again tomorrow and see if I can catch the area wet.
The circle in red I think is where leak is coming from, but there is too much clutter it is hard to tell. I didnt realize the engine has 2 thermostats.
The leak is likely coming from one of the smaller hoses coming out of the water pump housing.
I cannot find the diagram of those smaller hoses. Any idea what they are?

Took another look and a picture.
I believe the leak is the hose attached in the area I circled on the diagram.
But I also notice the metal tube (red arrow on top) that seems to have a leak too. Does this means I have to replace the thermostat housing?
I looked on Rockauto and other Auto parts stores and none of them have that particular type with that extra metal tube coming out (top arrow).
See arrows on attached photo.

What you're looking at is the water pipe, which is separate from the water outlet. Try this diagram instead:

WOW !!!! This is it!!
So now looking at that, I see I need the following:
14053MA water pipe
21049+A Seal O-ring
14056+A Hose
Then I need the hose that goes to the bottom of SEC210 where the red circle is.
I cannot see where it goes. I just see it going to the driver side under the battery.
What is this hose for?

Gee V-Star, you get FIVE BIG stars!! I spent 1/2 the day trying to find a decent diagram, and it looks like you found in pretty quick!
I really appreciate your help!

That would be the upper beehive hose for the transmission. You can find it here:
