well i didnt have a 3/8" drive breaker bar i used a rather small and cheap ratchet, just so happens the head on it was narrow enough to fit between the belt tensioner and fan. i damn near sprained my shoulder holding the thing up till i could put the allen wrench in.

I used this tool (Lisle Serpentine belt tool | Product Details | Pep Boys) and was able to remove the belt without taking any parts (radiator reservoir, fan, pulley) off the car. I went from below and only removed the plastic guard.
I am not a mechanic and this job took me no more then 1 hour.

Just did this today and used a Craftsman serpentine belt tool which worked well. Also jacked up the car for access and didn't have to remove any bolts to remove/replace the belt. Overall this worked well....thanks for the sticky!

NO worry about torque spec, the tensioner applies constant pressure against the belt, keeping it taut. Also FYI, for anyone who doesn't already know, you can rent the belt tensioner tool at autozone for about $30. This is the full up pro version, with every conceivable attachment. You take it back, you get your $30. FREE, which is hard to beat. Why buy a tool you will use once every 5 yrs, if that. This is a very simple job with the belt tool.

now you have the tensioner locked open take the belt off, you will now notice an odd design to the belt routing since you can't simply pull it off. the belt is stuck behind the tensioner, best way to get it off is to climb under the car and remove 2-3 10mm bolts that keep that little window shut. this is where you may need to jack the car up, i didnt since im quite thin and i just barely fit, so if you're not skinny or consider yourself thin jack the car up before this step. stick your hand up and loosen the little sob.
For those who will do this in the future, it would be much easier if you jack the car up and remove the cover under the car. Being able to see the pulleys from the bottom of your car would help you easily remove the old belt and route the new one.
Also, for some reason my 3/8'' breaker bar wouldn't fit the hole to loose the tensioner, so I went to advanceautoparts and rented the serpentine tool kit. It was basically free because they fully refunded me when I returned the kit.
