I found this question while searching for an answer to the very same problem after the belt broke. To replace it is really easy (once you discover how to do it!). Once you open the hood and face the engine, you will see to wheels without grooves. The one on your left is the one that tense the belt. To loosen the belt, just place a wrench at the 12 position and turn it clockwise to, say about 3 o'clock. That will move the wheel down and will release the pressure on the belt. To put a new one, just do the same. Please note that to remove the old belt (if it is not broken) or to place the new one IT IS NOT necessary to remove the small belt that you see attached to the radiator fan, just go with the new belt around and below the fan (between the fan and the radiator).
It all depends on the setup though. REMOVAL
