To replace the belt, the tensioner need to be released using the hex key right?

What size of the wrench and hex key need to do the work, replacing the serpentine of the vehicle listed above?

You turn the bolt (not the hex head) counterclockwise. This will remove the tension from the belt and you will be able to slip it off one of the pulleys and then you can release the tensioner.

As for the bolt sizes, we don't have them as they are not listed. However, it looks like a 13mm so I would start with that and if it is too large or too small, go up or down one size wrench until you find it.

Let us know what questions you have. Thanks
