Does any one know of a link that will give me the directions on how to change the Serpentine Belt on an 04 FX35?

Thanks

Welcome to Nico!

We have an article here on replacing the belts on a G. Since they have the same engine they also share the same belt setup on the earlier models.

The key difference is that you will need to remove the lower splash shield to access the tensioners with ease.

Replacing Drive Belts

It is a pretty straight forward procedure, a quick word of advise it to make sure that your lined up on every rib of every pulley before starting. I have seen many people start the car and be off on rib on a pulley and destroy a brand new belt in seconds.

Good Luck
