What engine do you have that has a timing belt, not a timing chain. Take the serpentine belt off and spin the pulleys individually and find the grinding noise.

Its a 3.1 liter. I don't have a clue how to take off belt. But thx for reply. At least I know it could be one of those components. Thx

It has a timing chain as well. 3/8 drive ratchet for the belt tensioner and loosen tension. Easy as pie, getting it back on is different. Maybe someone could help you.
