I've taken my belt so many times that I can tell you from the top of my head.
On the far end there's the Power Steering pulley, right? then the next one (on top) is the water pump pulley. Ok, now in between them and slightly lower, but not as low as the crank pulley, there's the tensioner pulley. It's a 17mm nut and you have to push it down with your ratchet.
You might need a cloth to grab hold firmly of your ratchet and apply more pressure to release the belt.
Taking the battery and battery tray makes things a LOT easier of course.
When putting the new belt in, just as a tip, make sure you leave the alternator pulley to be the last one to fit the belt to, so you can easily slide it in when pushing down on the tensioner.
I hope this quick answer helps you.
(btw, not proud of taking my belt so many times, but I have quite a story now with my car pulleys and pumps hehe)
