OE 21353-3N400 — Plate ASSY Water Pump for Hyundai

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the plate assy water pump should be inspected, and reference 21353-3N400 replaced if it measures outside specification.

Incoming batches pass a dimensional check, a material look-up against the cooling system specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

Position depends on the platform. On most Hyundai applications the plate assy water pump sits on the cooling system assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

KingMay supplies OEM-grade aftermarket parts built to the 21353-3N400 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.

Stock references leave Guangzhou within 7 working days. If 21353-3N400 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.
