A new alternator for a 2020 Nissan Altima typically runs roughly between $180 and $600 for the part, with the total installed price usually between about $350 and $900 depending on the chosen part type and labor rates. This article breaks down the main cost factors, options, and where to shop for the best value.
Pricing overview
Prices for a new alternator can vary widely based on whether you buy an OEM (dealer) part, an aftermarket part, or a remanufactured unit. The 2020 Altima may use different engine configurations, which can influence part fit and price. The ranges below reflect common market prices in recent years and can vary by location and vendor.
Here are common price ranges for a brand-new alternator suitable for a 2020 Nissan Altima:
- OEM/new (dealer-sourced or factory-equivalent): typically $350–$600.
- Aftermarket new (non-OEM but compatible): typically $180–$350.
- OEM remanufactured (often labeled “Reman”): typically $150–$300.
Prices for remanufactured units are usually lower than truly new OEM parts, but may come with different warranty terms and lead times. Always verify compatibility with your exact Altima engine and year.
Labor costs and total installed price
In addition to the part itself, labor is a major component of the total cost. The replacement is a straightforward job for a skilled technician, but rates vary by shop and region.
- Estimated labor time: typically 1 to 2 hours, depending on access and vehicle configuration.
- Average hourly labor rate: roughly $75 to $150 in many parts of the United States; higher in urban or dealer settings.
- Estimated installed total (part + labor):
- OEM new: about $470–$820 total.
- Aftermarket new: about $300–$620 total.
- OEM remanufactured: about $250–$550 total.
Note that taxes, shop fees, and any diagnostics needed before replacement can affect the final number. If you go to a dealership, you may see higher labor rates but a warranty that’s straightforward to transfer.
Where to buy and what to expect
Where you purchase the alternator can influence price, warranty, and return policy. It’s wise to compare multiple sources to ensure you get a unit that fits your exact engine variant and comes with a clear warranty.
- Dealer/OEM parts: typically the most expensive option but often provides the most seamless fit and the strongest warranty.
- Auto parts chains (e.g., AutoZone, Advance Auto Parts, O'Reilly): usually price-competitive with solid warranties and easier in-store pickup.
- Online retailers or marketplaces: can offer the best upfront price, but verify shipping costs, warranty terms, and return policies; beware of compatibility risks and potential core charges if buying reman.
Warranties for new OEM or aftermarket new units commonly range from 1 year to 2 years, while remanufactured units may carry shorter warranties. Check the warranty details and what conditions apply (e.g., misassembly, electrical surges, mileage limits) before purchase.
Summary
For a 2020 Nissan Altima, consider whether you want a genuinely new OEM part, an aftermarket new unit, or a remanufactured alternative. Expect part prices in the $180–$600 range and total installed costs roughly between $300 and $900, depending on the option you choose and local labor rates. Shopping around—comparing dealer quotes, national parts stores, and reputable online sellers—helps you balance price, fit, and warranty. If you’re on a tighter budget, a high-quality aftermarket new or OEM remanufactured unit can be a viable choice, but confirm compatibility with your engine and verify warranty terms before purchase.
In short, the best price for a new alternator depends on your engine variant, the source of the part, and the labor rate at the shop you choose. Always obtain multiple quotes and confirm warranty coverage to avoid surprises after the install.
