  6. In the front wheel well, remove the (2) retaining bolts using 7mm or 6mm sockets. Note: in the picture below, the 2nd bolt is covered by the chin spoiler – yours may or may not have a chin spoiler. If you have a chin spoiler, you will have to remove it first to gain access. (FIGURE 3)

  12. Before completely removing the entire bumper, ensure you disconnect the wire assemblies from both side marker lights and the temperature gauge sensor that is situated to the lower center of the bumper. (FIGURE 6)

  11. Now reverse the steps to reinstall the bumper cover with the attached lower fascia. It will be easier to reinstall the bumper with a second person, but is very possible to do alone.
  12. Ensure all the bolts and push tabs are replaced in the proper reverse order. Test all connections to ensure everything is secured.
  13. Note: I did not include installation for the fog lamps as there are two possible types.
