how to fix a leaking sunroof in my Honda Pilot YF3 (2016-2022)?

Solution

1. Preparation

• Tools Required: Screwdriver set, torx bits, trim removal tool, flashlight, towels.
• Disconnect the vehicle battery to avoid any electrical issues.
• Gather replacement parts if necessary (e.g., new seals or drainage tubes).

2. Inspect and Clean Drainage Channels

• Open the sunroof fully to access the drainage channels.
• Use a flashlight to locate the drainage holes at each corner of the sunroof.
• Clear any debris or blockages using a soft brush or compressed air.
• Pour a small amount of water into the channels to ensure it drains properly.

3. Replace the Sunroof Seal (if damaged)

• Remove the sunroof glass by unscrewing the retaining screws (use torx bits as required).
• Carefully lift the glass off and set it aside on a soft surface.
• Remove the old seal from the sunroof frame using a trim removal tool.
• Clean the surface where the new seal will be applied using isopropyl alcohol.
• Install the new seal by pressing it firmly into place, ensuring it is seated evenly.

4. Reinstall the Sunroof Glass

• Align the sunroof glass with the frame and gently lower it back into position.
• Reinstall the retaining screws, tightening them to the specified torque (consult the service manual for the exact torque value).
• Test the sunroof operation to ensure it opens and closes without any issues.

5. Final Inspection

• Check all drainage holes again to ensure they are clear.
• Run some water over the sunroof to test for leaks, ensuring it drains properly without entering the cabin.
• Clean any residual water inside the vehicle with towels and ensure the interior is dry.
