I replaced the polyrib/serpentine belt today on my 2.5 and it was so easy,follow these instructions and believe me you'll breeze it.
1) Move both seats full forward and tilt forward
2) Lift the front edge of the engine compartment carpet, where it meets the firewall carpet, and twist off the four plastic nuts (can be done by hand)
3) Lift the top edge of the firewall carpet off of the screws (you just removed the nuts) and take out the firewall carpet
4) Remove the engine access panel (silver) by removing the seven (IIRC) 10mm bolts and two 10mm nuts
5) Briefly sketch the roller wheel and belt layout. It's pretty simple so you can do the job without sketching the layout but better to be sure, right?
6) Find the two small roller wheels in the middle of the engine front. These are the belt tension rollers. One of them has a large nut in the center, the other does not. The one with the nut is the spring tension roller, the one without is just an idler.
7) Use the 24mm socket and long rachet to remove the belt. Place the socket over the nut and lean on the rachet. As you lean on the rachet the spring tension roller will smoothly release. You are NOT removing the nut, so don't expect it to spin; it will be a springy sensation. While you lean on the rachet to release pressure from the belt, use your other hand to slip the belt off of the other small (idle) roller. Then release the rachet and allow the tension roller to return to it's normal position.
Remove the belt from the pulleys.
9) Place the new belt over all of the pulleys and over the tension roller, but not over the idle roller.
10) Lean back onto the rachet, compressing the tension roller, and slip the belt over the idle roller. Eyeball everything once and then release the tension.
11) Inspect to make sure everything is right, then replace all of the covers.

Good instructions. The access panel can have sharp edges so watch out.
