Product Details
Valeo’s Alternator line focuses on OE-quality electrical replacement parts for modern charging systems. Part number 501805 follows the original equipment layout used on select Nissan Armada, NV2500, NV3500, and INFINITI QX56/QX80 applications, helping maintain proper charging voltage and stable electrical performance. The design is tested under thermal, vibration, and electrical stress conditions to verify durability in demanding service.
This part cross-references DENSO Auto Parts 210-4010 for the same application.
Common Charging System Issues
- Battery warning light or charging system fault codes
- Low battery voltage after driving
- Dim lights or unstable electrical output
- Noise or belt-drive concerns from a worn alternator pulley or bearing
- Charging failure on high-demand vehicles with multiple electrical loads
Installation Notes
Verify connector style, pulley groove count, rotation direction, and amperage rating before installation. Confirm the vehicle uses the listed 3-terminal female connection and serpentine belt configuration. Inspect the belt, tensioner, and charging circuit condition during replacement to help ensure proper system operation.
Quality Assurance
Valeo has supplied automotive electrical systems since 1923, and this alternator is built as a new OE-style replacement rather than a remanufactured unit. It is tested for extended exposure to heat, vibration, and electrical load to support long-term reliability in compatible Nissan and INFINITI applications.
