How It Works
The washer reservoir stores windshield washer fluid and supplies it to the washer pump(s) when activated. The pump pressurizes the fluid, which is routed through hoses to the nozzles and sprayed onto the windscreen. Some reservoirs also incorporate level sensors or mounting interfaces for washer pumps. If the tank cracks or leaks, fluid cannot be delivered and the washer system will fail to operate properly.
How To Replace
- Skill Level: Moderate. Suitable for experienced DIYers and professional mechanics.
- Basic Steps: Drain remaining washer fluid, remove any plastic clips or trim obstructing access, disconnect electrical connector(s) for the pump(s), disconnect washer hoses, unbolt or unclip the reservoir, remove and replace with the new unit, reconnect hoses and electrical connectors, refill with washer fluid and test for leaks and pump operation.
- Tips: Support the reservoir while removing fasteners to avoid stress on hoses and connectors. If reusing the original pump, inspect its seal and inlet strainer; replace if brittle or damaged.
Most Common Failure Reasons
- Physical Damage: Impact from road debris or collisions can crack the plastic body.
- Environmental Degradation: Prolonged UV exposure, extreme temperature cycles and freezing of water-rich mixtures can cause material brittleness and splitting.
- Mounting Fatigue: Vibrations and corroded mounting points or clips can cause stress cracks where the reservoir is secured.
- Pump/Seal Wear: Leaking or failed pump seals at the reservoir interface can give the appearance of a leaking tank even when the tank itself is intact.
