Step-by-Step Bumper Cover Removal

This guide assumes a basic understanding of automotive repair. If you're uncomfortable working on your vehicle, it's best to seek professional assistance.

Step 1: Preparation

• Park your CLS450 on a level surface and engage the parking brake.
• Consult your owner's manual for specific instructions or diagrams relevant to your model year.

Step 2: Wheel Well Access

• Carefully remove the wheel well liners. These are typically held in place by plastic fasteners that can be removed with plastic trim removal tools.

Step 3: Underbody Fasteners

• Locate the fasteners securing the bumper cover to the underbody. These are often screws or bolts. Remove them carefully using the appropriate tools.

Step 4: Fender & Headlight Connections

• There are typically several clips and fasteners connecting the bumper cover to the fenders and headlights. Carefully work these loose using the plastic trim removal tools. Take your time and avoid excessive force.

Step 5: Grille and Other Connections

• Disengage any connections to the grille or other components. Depending on the year and specific options, there may be additional connectors to consider.

Step 6: Gently Lower the Bumper Cover

• Once all fasteners and clips are released, carefully lower the bumper cover away from the vehicle. Be mindful of any wiring harnesses or other components that may still be attached.

Step 7: Disconnect Wiring Harnesses

• Carefully disconnect any remaining wiring harnesses. Take note of their location and orientation for easy reassembly.

Reassembly: Following the Steps in Reverse

Reassembly is simply a reversal of the removal process. Ensure all fasteners and clips are securely reattached, and double-check all wiring connections before securing the bumper cover.

Troubleshooting Common Issues

• Broken Clips: If clips break during removal, replacements are readily available online or at auto parts stores.
• Difficulty Removing Fasteners: Use the correct tools and apply gentle but firm pressure to avoid stripping the fasteners.
• Wiring Harness Issues: Carefully inspect the wiring harnesses for any damage during removal and reassembly.
