Genuine Nissan alternators are matched to the engine, not just the model name. This page lists 135 alternators along with serpentine belts, accessory drive belts and mounting brackets, and the engine size in the notes is usually what decides which one you need.
One Model, More Than One Alternator
Engine size splits the part
The Altima shows it clearly. 23100-6CA0A is listed for the 2019 to 2022 Altima with the 2.5 liter, and 23100-9HF0A for the 2.5 liter from 2023 to 2025, while the 2.0 liter turbo uses 23100-6CB0A for 2019 to 2024. The Murano follows the same pattern: 23100-6SX0A is listed for the 2025 and 2026 Murano with the 2.0 liter.
Build date on small crossovers
On the Kicks, 23100-5RA1B is listed up to October 2019 and 23100-5RA2B from October 2019, a part that also fits the Versa. The 2025 and 2026 Kicks with the 2.0 liter moves to 23100-7LG0A. The Rogue Sport uses 23100-4BB0A, and 23100-6RA0A is listed for the 2021 Japan built Rogue with the 2.5 liter.
Older vehicles
Alternators for earlier models are here too. 23100-JA02C is listed for the 2.5 liter Rogue and Rogue Select, and 2310M-CN10ARW for the 2003 to 2007 Murano. 2310M-4S100RW is a new unit for the 3.3 liter Frontier and Xterra.
Belts and brackets
Behind the alternators sit 30 serpentine belts, 17 accessory drive belts, 29 bracket bolts and 14 brackets. A worn belt slips under load and can mimic a weak alternator, so inspect it first and replace it with the alternator if it shows cracks or a glazed surface.
Heat and electrical load
Long Tennessee summers keep the A/C and cooling fans running hard, which adds load to the charging system. A battery light, dim headlights at idle, a battery that drains overnight or a whine from the engine bay are the usual signs of trouble. Test the battery as well, since a failing battery can wear out a new alternator. Check the ground straps and battery terminals too: a loose or corroded connection can make a healthy alternator look like it is failing. Cleaning those connections is free and often worth doing before buying parts. Related pages: electronics, headlights, towing parts and brakes.
FAQs
Does the Altima 2.0 turbo use the same alternator as the 2.5?

Which alternator fits my Kicks?
It depends on the build date and engine: 23100-5RA1B to October 2019, 23100-5RA2B after that, and 23100-7LG0A for the 2.0 liter.
