Default Drive/Serpentine Belt Tensioner Replacement

Has anyone done a drive belt tensioner on a AWD 4th gen? Can’t seem to find anything online, looking for tips, tutorials or any special tools that may be needed, thanks.

Thank but I’m looking on how to replace the tensioner pulley, not the belt.

The pulley on the alternator or next to the alternator?

Alternator decoupler. On the actual alternator shaft. Need a special tool.
Mine showed signs of grease leak from the rear once I removed it and inspected. Luckily replaced it as it is not listed as a service item.

Sometimes I think they want the parts to fail so don’t advise us of simple serviceable items to change on schedule.
