This OEM alternator is a new rotating electrical component supplied as each, with part number 3730027021. It is listed for Hyundai applications and is intended to suit the vehicle’s charging system where the correct alternator specification and mounting arrangement match the original unit.

As a new alternator, it is supplied as a replacement component rather than a remanufactured unit.

Application and Buying Notes

When checking this alternator, the first point to confirm is the part number 3730027021 against the unit you are removing. Alternators can look similar across model years, but the charging output, connector arrangement, and mounting style need to line up with the vehicle’s original part for the fit to be correct.

The fitment information supplied points to Hyundai and Hyundai Grandeur applications, including Grandeur 2006 through 2010. If your vehicle is in that range, compare the removed alternator with the replacement carefully before fitting. Even within a single model line, there can be differences that are not obvious from the outside.

Because this is a new OEM alternator, it is appropriate for buyers who want a direct replacement component rather than a repaired or remanufactured unit. The listed warranty is manufactures defect, so keep the packaging and part details in case you need to refer back to the supply record.

If the vehicle is being diagnosed for charging issues, remember that the alternator is only one part of the electrical system. Battery condition, wiring, belt condition, connectors, and the vehicle’s charging circuit should all be checked before installation so the replacement is assessed in the right context.

For practical buying, match the Hyundai application, the part number 3730027021, and the physical comparison with the old unit. That is the safest way to reduce the chance of ordering the wrong alternator when several similar variants may exist across the Grandeur range.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 3730027021 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.
