I am needing some help on how the belt goes on these three small pulleys on top of engine mainly the one in the middle.
If I look at the diagrams for this it's seems like the diagrams are missing a couple of pulleys that I have. The 3 pullies are circled in the picture. I think the first one closest to the compressor is the idler pulley? Not sure what the other two are.

It almost seems like one of them is a secondary belt tensioner?

If you have a diagram of how it should go on it would be much appreciated!
