could be however the harmonic pulley seems more likely, to check this __ with the engine running put a large srewdriver behind to pulley, next, carefully put your ear to the pulley and see if you can hear the grinding noise from there

could be the alternator, water pump
take the belt and spin all the pulleys and listen for noise and make sure they turn smoothly
another trick is to take a can of wd40 or equivalent and spray the bearings 1 at a time till the noise goes away or quiets down

The Tensioner Pulley Bearings are failing and either the Tensioner Pulley or the Tensioner Assembly (Pulley, Arm and Base) must be removed and replaced.
Click on the following free direct Link. It has several of the Serpentine Belt Diagrams and Tensioners that are possible with your 4.3L V6 engine.
1. Remove the Serpentine Belt.
Standard Rules to Removal the Serpentine Belt with a Tensioner:
A. Find the Tensioner(s). (See Diagrams on Link)
B. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (on the Pulley or Arm Base) OR the OPENING (3/8ths or 1/2 inch square opening) rotating the Tensioner Pulley/Arm - moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
C. Remove the loosened belt off one of the other more easily accessed Pulleys.
D. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.
Removing the Tensioner Pulley: See the Diagrams in the Link.
After the Belt has been removed, with the Tensioner resting:
DEPENDING ON WHAT TYPE TENSIONER:
IF the Tensioner Pulley itself HAS a Bolt Head showing, SOME of these bolts can be removed and the Tensioner Pulley replaced.
IF the Tensioner Pulley itself DOES NOT HAVE a Bolt Head showing, then go to the Tensioner Base located at the end of the Tensioner Arm. This should have a Bolt Head Showing. Remove this Bolt and the whole Tensioner Assembly will com off.
When replacing the Tensioner Assembly - MAKE SURE you place the protruding "nipple" on the underside base of the Tesnioner into the appropriate cavity on the engine face.
Standard Rules for Installing the Serpentine Belt with Tensioners:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them
