How To Install A New Glass Window Convertible Top On A Porsche Boxster (986)

Introduction

This tutorial will guide you through the process of installing a new glass window convertible top on a Porsche Boxster (986). If your current convertible top has a deteriorating plastic rear window, upgrading to a glass rear window can enhance both aesthetics and functionality. Follow these detailed steps to successfully replace your top, using tools and materials that are easy to find.

Step 1: Gather Your Tools and Materials

Before starting the installation, ensure you have all the necessary tools and materials ready:

• Screwdrivers: #1 Phillips, 1/4” flat tip, and star
• Ratchet with a 10mm socket
• Contact cement spray adhesive (3M™ Yellow Super Trim Adhesive 08090)
• Scissors and a razor blade
• Black electrical tape
• Straight pick (6”)
• Push-type clip removal tool
• 2” putty knife
• Rubber mallet
• New convertible top with a glass window

Step 2: Remove the Old Convertible Top

Carefully remove the existing convertible top to prepare for the new installation:

1. Detach the Interior Trim: Use the appropriate screwdriver to remove screws holding the interior trim in place. Be cautious not to damage the trim.
2. Remove the Old Top:
   • Unclip any fasteners that secure the top to the car frame.
   • Use the push-type clip removal tool to help detach clips without breaking them.
   • Cut away any adhesive around the old top with a razor blade for easier removal.
3. Take Off the Plastic Window: If applicable, carefully cut and remove the old plastic rear window.

Step 3: Prepare the New Top

Before installing the new top, ensure it is ready for fitting:

1. Lay Out the New Top: Unfold the new glass window convertible top and lay it flat to eliminate any creases.
2. Check Alignment: Position the top over the car to verify it aligns correctly with the frame.

Step 4: Install the New Convertible Top

Now, begin the installation of the new top:

1. Attach the New Top to the Frame:
   • Start at the front, securing the top to the windshield frame.
   • Use the rubber mallet to gently fit the top into place if necessary.
2. Secure the Sides:
   • Pull the sides of the top tight and secure them to the side frames with screws and clips.
   • Ensure the top is taut to prevent flapping while driving.
3. Seal the Edges: Apply the contact cement spray adhesive along the edges where the top meets the frame. Follow the adhesive instructions for best results.

Step 5: Reattach the Interior Trim

After securing the top, reassemble the interior:

1. Reinstall the Trim Pieces: Align and attach the interior trim back onto the frame, securing with screws.
2. Check for Gaps: Ensure everything fits snugly without gaps that could lead to leaks.

Conclusion

By following these steps, you can successfully install a new glass window convertible top on your Porsche Boxster. This upgrade not only improves your vehicle's appearance but also enhances its durability. For maintenance, regularly check the seals and the condition of the top to prolong its lifespan.
