the hardest part is loosening/tightening the tensioner bolt thing on the alternator. Its just hard to get at. Other then that just be sure that the grooves are matched up properly on the pulleys and its not that hard.
Well I have the 2 ltr engine and it was quite a bit of work to change both belts. The problem is with the alternator (if I recall correctly) where I had climb under the car the loosen the pivot bolt before I could use the adjuster bolt. I broke the adjuster bolt and had to order a replacement. It was also difficult getting my belts on the lower engine pully as the clearance between it and the body work was just about a 1/4 inch.
Trey, Im a girl...but I dont think I have small girly hands. heh. Well, the belts were changed a few days ago...took about 20 mins to do both belts. If the car were a v6, I would have almost no room. But it wasnt too hard. My car is happy, although the old belts were in pretty good shape...just getting old.
I did the same thing. Thought I needed new ones, bought them, tightened the old ones and they were fine. Then a few months later I swapped the new ones in anyway. Don't ask me why, I just like new stuff.
