Mercedes Sprinter Washer Pump Grommet – Genuine Mercedes-Benz | All Generations | #0019987301 (2001+)

A degraded or missing washer pump grommet on a Mercedes Sprinter creates a slow washer fluid leak at the pump-to-reservoir interface — draining the washer reservoir gradually and leaving the windshield washer system without fluid at exactly the wrong moment. This is the Genuine Mercedes-Benz washer pump grommet for all Sprinter generations, a direct replacement that restores the sealing interface between the washer fluid reservoir and the pump motor.

What This Part Does

The washer pump grommet is a rubber sealing element that sits in the reservoir bore where the electric washer pump motor is inserted. It compresses against the pump body and reservoir opening to create a watertight seal that prevents washer fluid from seeping past the pump mounting point. When the grommet hardens from age and chemical exposure, cracks, or deforms from removal during pump service, it loses its sealing contact and fluid begins to escape around the pump — causing gradual unnoticed fluid loss.

Common Symptoms of a Failed Washer Pump Grommet

• Washer fluid reservoir emptying faster than washer use would explain
• Visible washer fluid dripping or residue at the pump mounting point on the reservoir
• Washer fluid smell from the engine bay or wheel well area
• No washer fluid reaching the nozzles despite a full reservoir

When to Replace

Replace any time the washer pump is removed for service — never reinstall a used grommet. Also replace when fluid loss is traced to the pump mounting point.
