OE 1638103493 — Rearview Mirror for Hyundai / Kia

Three checks: the code printed on your old part must read 1638103493; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

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 body & interior reference and narrow by build year. Send photos and we will cross-check the number for you.

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.

A supersession happens when the maker revises a rearview mirror 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 1638103493 we list the current reference; ask our desk for written confirmation before a large order.

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.

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.
