The alternator charges your battery and powers your car's electrical system. When it fails, your car will eventually die — but the repair is straightforward and shouldn't break the bank.
Cost Breakdown
| Option | Parts | Total Installed |
|---|
| Remanufactured alternator | $100–$350 | $300–$700 |
| New aftermarket alternator | $150–$400 | $400–$900 |
| New OEM alternator | $250–$600 | $500–$1,200 |
Remanufactured alternators are the best value for most vehicles. They're factory-rebuilt with new bearings, brushes, and diodes, tested to OEM specs, and come with a warranty. The performance difference versus new is negligible.
