Installation / Application:
- Difficulty: 2/5
- Estimated time: 30-60 minutes
Instructions:
- Park vehicle on level ground and work in a dry, shaded area.
- Remove old vent seals and tailgate seal: open vent windows and/or tailgate and carefully pry out retaining clips or screws and peel away deteriorated rubber.
- Clean all mounting channels and mating surfaces with rubbing alcohol or an appropriate cleaner until free of adhesive residue, dirt, and oil; allow to dry.
- Test-fit each new seal to confirm orientation and any trimming required; mark trim lines with masking tape.
- If adhesive is used, apply a thin, even bead of weatherstrip adhesive to the channel or seal flange per adhesive instructions.
- Press the new vent seals into the channel firmly, working from one end to the other; use masking tape to hold seals in position while adhesive sets if needed.
- Install the tailgate seal by aligning it around the tailgate perimeter; trim excess with a utility knife and seat the seal into the channel, securing with clips or adhesive as applicable.
- Reinstall any retainers, screws, or hardware previously removed and verify proper operation of vents, windows, and tailgate.
- Allow adhesive to cure per manufacturer recommendations (typically 24 hours) before exposing to water or rigorous use.
- Perform a final inspection for gaps and test for leaks or wind noise; make minor adjustments as necessary.
