A supersession happens when the maker revises a gasket water 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 21354-3N440 we list the current reference; ask our desk for written confirmation before a large order.

Wholesale pricing for 21354-3N440 depends on order quantity, surface treatment and packing. Standard references are quoted ex-Guangzhou with tiered pricing from 10 pieces upward — send quantity and destination port and a quotation usually returns within one business day.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

Stock references leave Guangzhou within 7 working days. If 21354-3N440 needs a production run, allow 25-35 days depending on quantity and surface treatment. The schedule is confirmed in writing when the order is placed.
