Power steering belt
There are two bolts you need to loosen. One is the hinge bolt (the one circled) and one is the adjustment (cinch) bolt, which is down lower. There actually might be two....one on each side of the block bracket. There's not a lot of movement on that particular design, but, there should be enough to get the correct belt on. Just don't pry on the reservoir. That's a sure way to get a leak. Once it's loose, I just use my hand to move the pump and apply tension to the belt.
