2002 Chevrolet Monte Carlo Q&A

2002 Chevrolet Monte Carlo Question: I can't get my serpentine belt tight. Anyone have link to replace? Engine 3.4.

When I tighten the tensioner it seems like it is starting to get tight then it gets real loose again. Is it hard to replace the Tensioner if its loose? FYI I am not mechanically inclined. Thanks for any response. -
Answer 1
sounds like the tensioner but if you are not mechanically inclined I would take it to a mechanic -
