How to Properly Install Rear Hatch Glass in a Fox Body: A Step-by-Step Guide

Introduction

Are you a proud owner of a 1980 Mercury Capri with a Fox body? Perhaps, like me, you've had to remove the rear hatch glass to install a new pinch weld gasket. However, you may have encountered issues similar to others who struggled due to a poorly reinforced old seal. In this guide, I will walk you through the correct steps to install rear hatch glass in your Fox body, ensuring it matches the efficiency and quality you expect.

Issue with Original Seal

One of the common challenges faced by enthusiasts is dealing with the original seals, which often require a bit of effort to remove due to their reinforcement (e.g., butyl tape, twine). This process can sometimes lead to frustration and even damage if you're not careful. If you've had to remove the glass to replace the seal, you might have found yourself in a bind, such as the scenario described by another forum member. Allow me to break down the proper steps to avoid such issues.

Proper Installation Steps

First, let's discuss the proper way to replace the hatch seal without having to remove the rear hatch glass.

Step 1: Preparation

1. Safety First: Ensure you are in a well-lit and ventilated workspace with minimal distractions.

2. Tools Needed: A set of common wrenches, a wire brush or wire wheel, and appropriate sealant (if desired).

Step 2: Remove the Old Seal

1. Access the Trunk: Unlock and open the trunk lid.

2. Remove the Old Seal: Carefully pull the old seal off the edge of the hatch. If adhered with glue, scraping it off with a wire brush or wire wheel can help. Ensure you remove all remnants to avoid leakage.

Step 3: Clean the Area

1. Thorough Cleaning: Use a wire brush or wire wheel to remove any old seal or adhesive residue. This will ensure a clean surface for the new seal.

Step 4: Install the New Seal

1. Apply Sealant (Optional): If you prefer, apply a thin layer of sealant to the edges of the new seal to assist in adhesion.

2. Insert the New Seal: Push the new seal into place and ensure it fits snugly along the edge of the hatch.

Step 5: Final Touches

1. Reassemble the Hatch: Close the trunk, making sure everything is secure.

2. Inspection: Check for any leaks or misalignment once the door is closed.

Common Issues and Solutions

While the above steps should work well, some individuals, like those mentioned in the forum, have encountered difficulties. The key to resolving these issues lies in the proper application of the seal and thorough cleaning.

If you followed the steps but still find issues, there are a few things to consider:

Inadequate Seal Removal: Ensure you completely remove old seal and adhesive residue. Improper Seal Installation: Double-check that the new seal is seated properly and there are no gaps. Gluing the New Seal: If you choose to glue the new seal, ensure it is applied evenly and not too much to avoid puffing or bubbles.

Conclusion

By following these steps and taking your time, you should be able to replace the rear hatch seal on your Fox body Mercury Capri without having to remove the glass. Always remember, proper preparation and attention to detail are key to a successful repair. Happy muscle car maintenance!
