Default how to replace serpentine belt tensioner assembly?

My belt tensioner is rattling and needs to be replaced. Anyone know the procedure steps to replace it? I know how to remove the belt and the pulley, but the tensioner is a different story.

you have to unbolt the alternator and the right side timing belt cover(passenger side) then remove the plastic cover that covers the belt tensioner.i did this last year.i will help if you remove the pulley to the tensioner when removing it.its not a hard job.took me about a hour and half to do.
