OE 25386-3K170 — Motor Radiator Cooli for Hyundai

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the motor radiator cooli should be inspected, and reference 25386-3K170 replaced if it measures outside specification.

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

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a motor radiator cooli the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

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.

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 electrical & sensors family — always confirm dimensions and connector layout before you swap.

Every shipment of 25386-3K170 leaves with a packing list, photo documentation and a QC report. Warranty terms are agreed per contract and reference that inspection record; claims are settled in writing against the documentation.
