How much does an alternator cost on a Subaru?
In most Subaru models, the alternator part costs roughly from $150 to $600, with installed prices typically ranging from about $350 to $900 depending on model, sourcing, and labor.
What drives the price
The price you pay for an alternator depends on several factors, including the specific Subaru model and engine, whether you choose a new OEM part, a remanufactured unit, or an aftermarket alternative, plus labor costs and any core charges. Understanding these factors helps set expectations for part and total installed costs.
Categories that affect price
The following categories cover the common options you’ll see when shopping for a Subaru alternator.
- New OEM Subaru alternator (parts only): typically about $300–$600 depending on model and supplier.
- Remanufactured or rebuilt alternator: typically about $150–$250.
- Aftermarket new alternator (non-OEM brand): typically about $180–$450.
- Used or salvage-yard replacement: often about $60–$150, with variable reliability and warranty.
Choosing among OEM, remanufactured, aftermarket, or used significantly influences reliability, warranty, and long-term cost beyond the initial price tag.
Price by Subaru model and configuration
While general ranges hold across the lineup, certain models and engine configurations push prices higher or lower. The most common Subaru platforms use belt-driven alternators, but newer or high-output configurations can affect both part price and compatibility.
By model family (typical ranges)
These ranges reflect common market prices for the part alone; totals will vary with labor and local taxes.
- Outback / Legacy with 2.5L engine: OEM about $320–$550; reman $150–$250.
- Forester (2.5L or newer 1.5L variants): OEM about $340–$580; reman $160–$240.
- Impreza / WRX (various engines): OEM about $320–$560; reman $170–$250.
- Ascent / higher-output variants: OEM about $380–$600; reman $180–$260.
Prices can vary by year, region, and supplier, and some dealers or shops may charge a core fee or shipping that alters the total outlay.
Labor costs and installation time
Labor costs depend on your location and the shop, as well as the accessibility of the alternator in your Subaru. Most installations are straightforward, but some models require more disassembly or belt removal.
- Typical labor time: around 1–3 hours, with newer or harder-to-access models leaning toward the longer end.
- Average labor rate: roughly $75–$150 per hour, varying by region and shop.
- Estimated installed price range (parts + labor): commonly $350–$900, depending on part choice and local labor rates.
Always request a full written quote that includes parts, labor, core charges (if any), and a warranty on both parts and labor where available.
How to shop for an alternator
To get the best value and reliability, compare several options and verify compatibility with your exact Subaru model, year, and engine code. Pay attention to amperage rating, pulley type, and warranty terms.
- Confirm compatibility: use your vehicle’s VIN or engine code to match the correct alternator part number and amperage rating.
- Compare quotes: include OEM dealers, reputable remanufacturers, and recognized aftermarket brands; watch for core charges and shipping.
- Check warranties: look for at least 1-year parts warranty; preferred shops offer labor warranty on installation.
- Factor in installation: decide whether you’ll install yourself (if experienced) or have a shop handle it, which affects total cost.
Getting multiple quotes and reading customer reviews can help you balance price, warranty, and reliability for your Subaru.
What else to consider
Beyond price, consider the reliability history of the chosen part, the shop’s reputation, and whether a remanufactured unit carries a shorter or longer warranty than a new OEM part. Also account for potential related maintenance items, such as belt replacement or tensioner wear, which can influence total repair costs.
Summary
Subaru alternator prices vary widely. Expect part-only costs roughly from $150 (used or remanufactured) up to $600 (new OEM, depending on model). Installed prices generally range from about $350 to $900, heavily influenced by labor rates, model complexity, and the part type chosen. To save money and ensure reliability, compare OEM, remanufactured, and aftermarket options, verify compatibility, and obtain clear quotes that include core charges and warranty terms. When in doubt, consult a trusted local shop for an accurate estimate tailored to your vehicle and location.

How long do Subaru Alternators last?
Alternators generally last about 150k in my experience, however I've seen some go at 90k and some go at 300k so it's just a part that goes when it goes. I would never change one before it starts showing issues unless it's to get more amps.
Is it worth fixing an alternator?
Whether it's worth fixing an alternator depends on the extent of the damage; minor issues like a loose belt or worn-out brushes are often more cost-effective to repair, while severe damage makes replacement the better option. Fixing a minor problem can save money and prevent more expensive damage to other electrical components, but if the alternator is old or the damage is catastrophic, replacing it with a new or rebuilt unit is recommended.
When to consider fixing it
- Minor issues: If the problem is simple, like a loose belt or a faulty diode, a repair is often a good idea.
- Cost savings: A minor repair can be significantly cheaper than buying a new part and can prevent future, more costly problems from developing.
- Relatively new part: If the alternator is not very old, it's more likely that a repair will be a worthwhile solution.
When to consider replacing it
- Extensive damage: If the alternator has suffered catastrophic damage, such as a broken housing, replacement is the only viable option.
- Old alternator: If the unit is old and nearing the end of its typical lifespan (80,000–150,000 miles or 7–10 years), replacing it with a new or rebuilt one is often more reliable in the long run.
- Cost-effectiveness: Sometimes, even for non-catastrophic issues, replacing the entire unit can be more cost-effective than attempting a complex repair.
