Well, on the 94 4.6L the Serpentine belt is on the passenger side of course. However, I recently noticed that there is another belt on the other side! What is that belt for? I'm curious because it seems like it could use a replacement. Thanks.

Duh! :bonkers: How hard is that to change? BTW Thanks.
It's pretty easy. One bolt and two small nuts removes the cover for it, then a 1/4" ratchet will give you the leverage you need to push the tensioner forward far enough to slip the belt off. Once it's loose from the pulleys, you'll have to remove the tensioner by removing the two double-sided bolts. It can be a minor challenge to get it away from the water pump pulley, which is kind of difficult to see, but if you really must replace it anyway, just cut the belt. To get the new one on there, I used a dull-tipped flat blade screwdriver to push it past the long portion of the water pump pulley and maneuvered it over the rest of them by hand. All in all, the belt replacement process took me about 10-15 minutes.

Hope that helps. Good luck and...
