SIMPLE install. Basic tools, no jacks required. Basically unbolt 5 nuts and/or bolts, slide the thing together (don't reuse the big washer) and tighten the thing back together!
It is helpful to remove a few gromets on that black (fabric?) stuff near the idler arm, to see the inner aspect of the frame (and the other side of the bolts you'll be working with).
