Depending on the mileage, I would look at the belt to check it's condition, if it's worn, replace it and the tensioner pulley or tensioner assembly. You can get a Bando belt and Goodyear tensioner on eBay for around $80.
The test for the newer belts is the depth of the ribs as well as obvious cracks. There's a depth gauge Goodyear provides to dealers, I have one in my glovebox but haven't needed it yet. Point is, it could be squeaking & needing to be replaced but still look OK.
