Understanding the Trunk Seal

The trunk seal, also known as the gasket, is a weatherstripping component that lines the perimeter of the trunk lid. It creates a watertight seal to prevent water, dust, and debris from entering the trunk. Over time, the seal can become damaged or worn, leading to leaks.

Diagnosing the Leak

To verify that the leak is indeed caused by a faulty trunk seal, perform a quick inspection. After a rainstorm or car wash, open the trunk and check the edges of the lid for any gaps or tears in the seal. If you notice any damage, it’s likely the culprit behind the leak.

Materials Needed

Before you begin the repair, gather the following materials:

• Replacement trunk seal (compatible with your vehicle make and model)
• Clean cloths or rags
• Scissors
• Sealant (optional)

Removing the Old Seal

1. Open the trunk and remove any loose items.

2. Locate the old trunk seal, which will be attached to the inside perimeter of the trunk lid.

3. Gently peel the old seal away from the trunk lid, taking care not to damage the paint or metal.

4. Use a clean cloth or rag to wipe away any residue left from the old seal.

Installing the New Seal

1. Test fit the new seal around the trunk lid to ensure a snug fit. Trim the seal to length if necessary, using scissors.

2. Apply a thin bead of sealant to the trunk lid where the seal will be installed. This step is optional but recommended for added watertightness.

3. Align the new seal with the trunk lid and press it firmly into place, starting at one corner and working your way around the perimeter. Make sure the seal is fully seated and there are no gaps.

4. Close the trunk and inspect the seal for any leaks. If you notice any leaks, repeat the installation process, ensuring that the seal is securely in place.
