How to Replace Belt Tensioner Assembly
Has anyone replaced the serpentine belt tensioner assembly and what needs to be removed to accomplish it? How difficult is this to do? Thanks.

Very easy job on the FA20. I did the tensioner as a preventative measure when I swapped out the old S belt and noisy idler pulleys. Took maybe 30mins for the whole job.

Is it necessary to move the alternator out of the way to get to any bolts that might be hidden by the alternator? Can you just replace the pulley itself without replacing the tensioner unit? Thanks
