Tires Plus inspection revealed cracks in the serpentine belt. Can you send me instructions and diagrams on how to change it out?

Also, is there an A/C belt as well, or does the A/C run off the single belt? Does one need to change out the pulleys themselves? I wouldn't think so but just asking.

Thanks

The pulleys do not need to be replaced unless they are damaged or making noise. In this case it sounds like just the belt is the issue.

As for an A/C belt, your vehicle only has one drive belt so that is all that is needed.

Unfortunately we don't have a diagram showing the routing so it is critical that you draw the routing or get a picture of it before you remove the belt. There is a picture here that gives most of the pulleys but it is not a actual diagram. You should also check on the radiator support under the hood. Some times the OEM puts the diagram there which is why it is not in the manual.

Let me know if you have questions. Thanks
