OE 2028690121 — Washer Pump for Mercedes-Benz

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the washer pump should be inspected, and reference 2028690121 replaced if it measures outside specification.

KingMay supplies OEM-grade aftermarket parts built to the 2028690121 factory specification: material grade, dimensional tolerance and surface finish follow the original tooling. They are not dealer-boxed genuine parts, and we quote them that way so there is no ambiguity at customs.

Aftermarket washer pump comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

A supersession happens when the maker revises a washer pump and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 2028690121 we list the current reference; ask our desk for written confirmation before a large order.

Report it with the order number and packing-list line plus photographs. Because every carton is photographed before loading, we can trace the batch immediately and settle the claim against the inspection record instead of arguing from memory.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 2028690121 with other cooling system references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.
