This generator alternator is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The factory-correct 12V 150A rating ensures reliable charging performance for Hyundai and Kia V6 vehicles.

Key physical specs: net weight 5.65 kg, gross weight 5.95 kg, overall dimensions 240 x 180 x 170 mm, supplied inside neutral kraft inner carton.

The Hyundai Kia V6 Charging Platform

Hyundai Azera, Grand Santa Fe, Santa Fe and Kia Cadenza, Carnival / Sedona and Sorento models use a 12V charging system with factory-spec generator alternators. The alternator numbering spans the Hyundai / Kia OE numbers (37300-3C510, 37300-3C520), the 104210 series (104210-1800, 104210-2870), the 11686 family (11686, 11686N), the UD series (UD14161A, UD11383A) and the numbers 11591, 11087 and 90-29-5784, all referring to the same charging-system family.

It is critical to verify the rated output and pulley configuration on your old alternator: this unit is rated at 12V 150A with a 6PK pulley. Alternators with a different output, pulley configuration or mounting pattern are not interchangeable with this unit.

Confirm the mounting flange pattern, terminal positions and bolt spacing against your original alternator before ordering. Always cross-check the OE numbers stamped on your old unit, including the 37300-3C510 family, before placing an order.

Technical Specifications

Compatibility and Cross Reference

According to the original product page, this alternator fits the application families summarized below. Do not rely solely on the brand name for fitment validation; always compare the original part number, mounting holes, pulley configuration and connector configuration before ordering.

Multiple Hyundai / Kia OE and aftermarket numbers appear across production batches and regional market specifications for this same alternator family. If your original unit bears one of the listed cross-reference numbers, 37300-3C510 serves as a direct drop-in replacement.

What to Look for in a Replacement

Follow these five verification steps before placing your order to avoid wrong-part returns:

• 1. Check the voltage and output rating on your old alternator: confirm it is rated for 12V 150A. Other ratings are not interchangeable.

• 2. Check the pulley configuration: this unit uses a 6PK pulley. Alternators with a different pulley groove count are incompatible.

• 3. Confirm the platform: Hyundai Azera, Grand Santa Fe, Santa Fe or Kia Cadenza, Carnival / Sedona, Sorento, K900 with a G6DF / G6DH / G6DG / G6DC engine. Other platforms may use different alternator assemblies.

• 4. Compare the mounting holes, flange pattern and connector configuration with your original alternator, and match OE numbers including the 37300-3C510 family.

• 5. Weight cross-check: genuine matching unit weighs approximately 5.65 kg net; significant weight difference indicates wrong assembly.

Application Scenarios

• Auto repair shops servicing Hyundai Azera, Grand Santa Fe, Santa Fe and Kia Cadenza, Carnival / Sedona, Sorento, K900 models with failed charging systems.

• Auto parts retailers and distributors stocking Hyundai / Kia alternators for the Korean vehicle aftermarket.

• Car owners and DIY enthusiasts replacing worn alternators with an original-spec new unit.

• Used car dealers refurbishing pre-owned Hyundai and Kia vehicles for resale.

• Exporters supplying Hyundai / Kia alternators to global markets.

FAQ

Q: Which vehicles does this alternator fit?
A: It fits Hyundai Azera 3.3L, Grand Santa Fe (G6DF / G6DH), Santa Fe (G6DC / G6DF), Kia Cadenza 3.3L, Carnival / Sedona (G6DH), Sorento (G6DC / G6DF) and the Kia K900. Confirm your exact model, year, engine and OE number before ordering, and check that your old alternator is a 12V 150A 6PK unit.

Q: My old alternator shows OE number 37300-3C520 or 104210-1800, will 37300-3C510 work?
A: Yes. These numbers belong to the same alternator family for the Hyundai / Kia V6 platform, differing only by production revision and market specification. It serves as a direct replacement.

Q: What is the correct charging voltage after installation?
A: A healthy 12V charging system should regulate at approximately 13.5-14.5V at the battery terminals with the engine running. If the voltage is out of range, check the alternator, regulator and wiring before further testing.

Q: Can I fit this alternator onto other vehicle brands?
A: No. Different vehicle families use different alternator mounting patterns, pulley configurations and terminal layouts. Confirm your vehicle model before ordering.

Q: What is the correct operation after installation?
A: The charging system should hold battery voltage at the regulated level and keep the charge warning light off under normal load. If the warning light stays on, check the alternator output and wiring connections.

Q: What is your warranty and lead-time?
A: Goods are in stock with a 10-day dispatch lead-time. A 1-year warranty applies from installation date; warranty excludes damage caused by mis-installation, incorrect wiring, water ingress, short circuit or physical damage.

In Practice

For technicians working on Hyundai and Kia vehicles: Before removing the existing alternator, confirm the engine is off and the battery is disconnected at the negative terminal first, and park the vehicle on a flat surface with the parking brake engaged. Remove the battery cable from the B+ terminal of the alternator, noting the correct orientation of each connection, and label or photograph the wiring before disconnecting.

Release the belt tensioner, remove the 6PK drive belt from the pulley and remove the mounting bolts supporting the alternator. Compare the new alternator against the old unit: verify mounting flange, bolt spacing, the 6PK pulley and connector configuration. Clean the mounting surface, position the new alternator, and tighten mounting bolts in stages to factory torque. Reinstall the drive belt, ensuring correct belt routing and tension, then reconnect the wiring and battery cable, ensuring terminals are clean and tight.

After installation, reconnect the battery and start the engine. Check that the alternator charges correctly: battery voltage should rise to approximately 13.5-14.5V with the engine running, the charge warning light should go out, and the alternator should run quietly without bearing noise or belt slip. If the warning light stays on or voltage is out of range, inspect the wiring, belt tension and alternator output before further testing.
