How to Remove the Front Bumper

  1. Open the hood.
  2. Release the upper part of the radiator grille from its clips and remove it upward (the grille is held by the hood latch mechanism; it’s not necessary to remove it completely, just lift it up).
  3. Under the radiator grille, unscrew the five screws securing the upper part of the front bumper.
  4. Remove the decorative side covers on the front bumper (held by clips).
  5. Under the covers, unscrew two screws.
  6. In the wheel arches, unscrew four screws on each side securing the fender liners (it’s easier with the wheels turned outward).
  7. With an assistant, pull the front bumper forward off the guide rails in the fenders (be careful not to damage electrical wires or hoses).
  8. Disconnect any electrical connectors (if present).
  9. (If equipped) Disconnect the headlight washer hoses.
