Sydasant Alternator 12V 110A Replacement for Nissan 2.5L (2007–2015) — 6-Groove Decoupler Pulley, Internal Regulator

This is a brand-new Sydasant 12V, 110A alternator designed to replace factory units in many Nissan 2.5L vehicles from 2007–2015, restoring reliable charging with a six-groove decoupler pulley and clockwise rotation.

If your Nissan Altima, Sentra, Rogue or Rogue Select is showing dim lights, a weak battery, or charging system warnings, an OEM-compatible alternator swap can get the electrical system back to spec. Sydasant’s unit is built with an aluminum housing, copper windings, and an internal regulator for steady output. Before buying, confirm the three-pin connector style and vehicle fitment — this model is engineered for select 2.5L L4 applications and matches many OEM part numbers.

Compatibility depends on engine size, trim, and connector type. This alternator fits specific 2.5L L4 variants of Altima, Sentra, Rogue and Rogue Select across the listed years; it only fits vehicles with a three-pin electrical plug. Use your vehicle details or parts look-up to verify match before ordering.
