I personally have never changed a fuel filter in that model year. You can Google it and find detailed instruction on all to do it. I would think that it would not be that big of a headache…

There should be a decal under the hood or on the radiator shroud showing the routing of the belt and naming the components. The tensioner is the pulley that is on a spring that can be moved with a breaker bar or belt adjusting tool. The other components should not be moveable.

It is under the car on either driver or passenger side in a metal bracket, the side to side location changes on some years and models, look just about where the front seats are bolted to the body, it is round about 6 inches long
