    If you need to ask here, this job most likely isn't for you, take it to a reputable repair shop, but if you insist, here goes,

    Looking from the passenger side into the engine bay, you will see 2 or 3 belts going around the power steering pump. alternator and such. these will need to come off. Then there will be bolts on the idler pulley , 2 if I remember. If you have the new part look at it and compare. A lot of the bolts to loosen the belts and such are difficult to get to so If you don't know how to work on cars, at least find a friend who does. Once you have all the belts and such reinstalled, you will need to apply tension to the belts. How this is done varies by vehicle. Hope this helps!

    Not intimately familiar with your car, but generally speaking you are going to have 2 or 3 bolts to take off, and just slap in the new one. If you are not normally a handi person, then just buy the part and take a look. Unless you are really super low on mechanical aptitude you are going to have no problem with it.

    The hardest part is using a long socket wrench to tension the spring and re-install the belt.
