the power steering belt is held in position by three 13mm bolts that pass from the rear of the pump to the front of the mount. nuts are in front, bolts are in rear, hold front nuts with an open end wrench, and get a 6" 3/8-drive extension with either a universal jointed 13mm socket, or a universal joint on the end of the extension and the socket. be careful around the fuel lines with the ratchet, ya don't wanna break it.
after you get all three bolts loose, there is a bolt head that is on the flat face of the pump mount right between the two hose connections. that is the adjuster bolt, and you loosen that until you have clearance to remove the belt. a 13mm gearwrench is best for this task, but it can be done with the socket/universal... it's just tight between the lines, and as the pump is loosened, the hoses move into/out of your way...

I don't recommend removing engine parts on a dirty engine, I would STRONGLY recommend cleaning it before beginning work, but in your case, I'd at least stuff a clean rag in the timing area, and scrape the goo off the engine, and clean around the pump opening well, remember to take the rag out before you put the vacuum pump back.
