The typical replacement cost for a 2011 Chevy Impala alternator ranges roughly from $60 to $300, depending on whether you choose a remanufactured unit, a new aftermarket part, or an OEM unit, and whether you buy new or used.
When shopping for this part, you’ll encounter several pricing pathways. The exact price depends on the alternator’s amperage rating and compatibility with your specific Impala model, the seller’s policies, and whether a core charge is involved. Labor costs for installation, if you hire a mechanic, are separate from the part price.

What affects the price
Several factors determine how much you will pay for the alternator. The main considerations include the unit’s amperage rating, whether the part is new, remanufactured, or used, and whether it is OEM/GM-approved or aftermarket.

- Condition: new, remanufactured, or used
- OEM vs aftermarket branding
- Retail channel and location, including in-store vs online
- Core charge and warranty terms
Always verify compatibility with your vehicle’s VIN and engine configuration, and factor in any installation labor if you’re not replacing the unit yourself.
Where to buy
Shopping options vary from local stores to online marketplaces. Each has its pros and cons in terms of price, warranty, and convenience.
- Major auto parts chains and retailers (e.g., AutoZone, Advance Auto Parts, O'Reilly Auto Parts)
- Online suppliers and marketplaces (e.g., RockAuto, large ecommerce retailers)
- GM dealership or Delco OEM parts sources
- Salvage yards and used-parts markets
When buying, compare warranties, return policies, and shipping times. Ensure the part matches your vehicle’s year, make, model, engine, and amperage requirement by confirming with the seller or checking your VIN.
Summary
For a 2011 Chevy Impala, plan for a part price in the broad range of $60–$300 depending on whether you choose remanufactured, new aftermarket, or OEM options, plus possible core charges and whether you need labor.
