Part prices for a Buick Regal alternator typically range from about $120 to $550 for the unit itself, depending on whether you choose a remanufactured, new OEM, or used part. Labor to install can add roughly $100 to $250, depending on location and shop rates.
The Buick Regal has multiple generations with different engines and amperage requirements, so the exact price and compatibility vary. This article outlines current market ranges, factors that affect cost, and tips for shopping the right alternator for your Regal.
What affects the price
Several factors determine the final price you'll pay for an alternator for a Buick Regal. These include whether the part is new OEM, remanufactured, or used; the engine and year; amperage rating; brand and retailer; and whether a core charge applies.
- New OEM (genuine GM) alternator
- Remanufactured/rebuilt alternator
- Used/exchange salvaged alternator
- High-output or turbo-specific variants (for certain Regal engines)
Prices scale with the type of part and the complexity of the engine. OEM units tend to be pricier, while remanufactured parts offer a balance of cost and warranty; used units are cheapest but carry higher risk of wear.
Typical price ranges (as of 2026)
Below are common price ranges you’ll see from major retailers and auto parts stores. These figures exclude tax and any labor charges, core deposits, or shipping fees.
- New OEM alternator: about $350–$550 (occasionally higher for rare model-year combinations)
- Remanufactured/rebuilt alternator: about $120–$250
- Used/ salvage alternator: about $60–$150
- High-output or specialty variants (for certain Regal engines): about $500–$700
Note that many sellers apply a core charge when you buy a new or remanufactured unit, which is refunded when you return a functional core. Always confirm amperage, connector type, mounting, and belt routing to ensure compatibility.
Labor considerations
Installing an alternator typically adds labor costs. In many shops, labor can range from roughly $100 to $250, depending on local rates, belt replacement needs, and whether any other parts (tensioner, serpentine belt, or hoses) are replaced during the job.
Where to buy and how to shop
Consider reputable retailers, including automotive parts chains, dealership parts departments, or trusted online sellers. To avoid mismatches, have your Regal's model year, engine code, and VIN handy to verify compatibility, amperage (e.g., 120A vs 150A), and connector type. Compare warranties and check if core charges apply.
Summary
For a Buick Regal, the total cost of replacing an alternator depends on the part type, engine, and whether you do it yourself or hire a shop. Expect the part itself to run roughly $120–$550, with labor typically $100–$250. By understanding your engine’s requirements and shopping around, you can balance cost with reliability and warranty coverage.
