How do you change a fan belt on a 2000 Isuzu rodeo?

I believe that you have the VG30 engine, if this is true you have to remove all of the belts and to do that you must find all of the adjuster screws for the accessories that are attached to the appropiate belts and lossen the pivot bolts. once all other belts are removed you can begin replacing. my advice is to replace all the belts while you are there and save your self from the hassle of this again.
