Hi, I have the car listed above SE model and I'm trying to replace the serpentine belt as part of the 100,000 maintenance for the car. I know where the tensioner is and which way to rotate it but it refuses to budge. Any thoughts?

If it is locked, it will need to be replaced. Since the belt may be too tight to get off, you may need to cut it off.

Here are directions for replacing the tensioner. The attached pic correlates with the directions.

Hi,

Yes. They both need to be removed. I believe the one in the middle is a reverse torx.

Let me know if you get it off.
