Compatibility And Application
Fits as the washer hose grommet/pass-through in the rear tailgate for Citroën C8 and Peugeot 807. The part seals the aperture where the washer hose passes through the tailgate sheet metal and supports the rear washer nozzle tubing to prevent chafing and leaks.
Function And Benefits
- Seals the washer hose entry point to prevent water ingress and corrosion inside the tailgate.
- Prevents washer hose chafing and mechanical wear by securing the hose in place.
- Maintains correct washer fluid routing to the rear nozzle for reliable cleaning performance.
- OEM-referenced fitment for straightforward identification and ordering by part number.
Replacement Procedure
Basic Steps (Typical For Tailgate Installations):
- Remove Tailgate Trim: Open the tailgate and carefully remove the interior trim panel to access the wiper motor and hose routing. Keep fasteners organized.
- Remove Wiper Arm/Nozzle If Necessary: Depending on access, you may need to remove the wiper arm or nozzle to free the hose and grommet area.
- Disconnect Washer Hose: Carefully detach the washer hose from the grommet/nozzle. Prepare a small drain container to catch residual fluid.
- Extract Old Grommet: Push or pry out the old grommet from the tailgate aperture. Inspect the hole for rust or deformation and clean the mating surface.
- Fit New Grommet: Lubricate the new grommet lightly with silicone grease or soapy water for easier installation, then press it into the aperture until fully seated.
- Reconnect Hose And Reassemble: Reconnect the washer hose, route it to avoid kinks, reinstall any removed components and the trim panel. Refill washer fluid if needed and test the rear washer for proper flow and sealing.
Installation Recommendations
- Use Silicone-Based Grease: A light coating of silicone grease helps install the rubber grommet without degrading the material.
- Inspect Hose And Clamps: Replace brittle or cracked hose sections and faulty clamps to prevent repeat leaks.
- Check For Corrosion: Clean and treat rust around the aperture before fitting the new grommet to ensure a durable seal.
- Test After Fitment: Operate the washer system and inspect for leaks at the grommet and along the hose routing.
- Safety Note: If Working Near Electrical Components, Isolate The Negative Battery Terminal As A Precaution.
Common Failure Modes
Rubber grommets in the rear washer system typically fail due to age-related degradation, UV exposure, and repeated mechanical stress. Common causes include:
- Rubber Hardening And Cracking From Heat And UV Exposure, Causing Leaks.
- Hose Wear Or Abrasion Against The Tailgate Edge When The Grommet Loses Its Cushioning Effect.
- Damage From Ice Or Debris, Especially In Cold Climates Where Water Can Freeze In The Hose Or Nozzle.
- Corrosion Around The Aperture That Prevents Proper Sealing.
Why Replace This Part
A failing grommet often leads to washer fluid leaking into the tailgate cavity, which can cause corrosion, impair rear wiper motor operation, and create electrical issues in connectors housed inside the tailgate. Replacing the grommet is a cost-effective preventive repair to maintain washer performance and protect bodywork and electronics.
