How to change serpentine 2008 fusion - 2008 Ford Fusion

Hello again :>D

Question edited to add maker and complete the year.
Question moved to model category.

If you have California emissions, then you will have 3 sensors. If you are getting a P0420 code, you can try changing the upstream sensor first. If you still get a P0420 code, then you will have to replace the manifold/catalytic convertor.

You need a serpentine belt tool, you can rent one at the parts place and while you are there get the new idler. You will also need a wrench to fit the bolt. Remove the belt then take the bolt out of the idler and install the new one, you can use some low strength loctite purple to keep this from happening again. Reinstall the belt, return the tool and get your money back for the rental.
