Starting at $3.95, AutoBuffy stocks 1 washer fluid reservoir mounting grommets from URO. This small rubber isolator seats the washer fluid reservoir against the body or bracket, absorbing vibration and preventing the plastic tank from cracking. When it deteriorates, the reservoir shifts, leaks at its base, or rattles — eventually causing washer system failure.
The main decision is material quality and fit: OEM-spec rubber grommets match the original durometer and hole diameter, while aftermarket options vary in stiffness and durability. Confirm whether your Land Rover Range Rover Sport uses one grommet or a set, and check whether the grommet is sold individually or as part of a hardware kit.
| Option | Best for | What you get |
|---|---|---|
| OEM-equivalent rubber grommet | Owners who want a factory-match fit and feel | Correct durometer, precise hole diameter, reliable long-term vibration isolation |
| Aftermarket economy grommet | Budget repairs or high-mileage vehicles not kept long-term | Lower cost, functional fit, may be slightly softer or harder than OEM spec |
| Reinforced heavy-duty grommet | Vehicles driven on rough roads or in extreme heat/cold climates | Thicker rubber or rubber-over-metal construction for superior tear resistance |
| Full hardware kit (grommet + bolt/stud) | When the mounting hardware is also damaged or corroded | Complete fastener set ensures the entire mount is renewed in one purchase |
Drain or remove the washer fluid reservoir to access the mounting points, then press or pry the old grommet out of the reservoir tab or body bracket and seat the new one firmly until it is fully recessed and flush. Reinstall the reservoir onto the mounting stud or bolt, ensuring the grommet seats evenly without pinching. No significant torque is required — snug the fastener until the reservoir is stable with no side-to-side movement.
