Help - - Where do I put the water?

[dDUBlya]

Im looking dead straight at my engine and have a large cream colored fluid box on the upper right hand side.
Is this where the water goes - the levels are below minimum.

Which car/model/engine/year?

Think I got it, well I put water in there yesterday and disasters.
Looked the obvious place anyway.
Cheers.
