OE 25329-J9000 — Filler Neck ASSY Radiator for Hyundai

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest cooling system reference and narrow by build year. Send photos and we will cross-check the number for you.

KingMay supplies OEM-grade aftermarket parts built to the 25329-J9000 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.

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the cooling system family — always confirm dimensions and connector layout before you swap.

Position depends on the platform. On most Hyundai applications the filler neck assy radiator 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.

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.

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.
