About Alternators
What do they do?
The alternator charges the battery and powers the electrical system while the engine is running. Modern cars with heated seats, screens, and multiple electronics put high demands on the alternator.
When to replace
Alternators typically last 100,000–150,000 miles. Symptoms of failure include the battery warning light, dim headlights, electrical system malfunctions, and a dead battery despite being recently charged. A whining noise from the engine bay can indicate a worn alternator bearing.
Brand guide
Bosch, Valeo, and Denso are the main OEM alternator manufacturers. Remanufactured (reconditioned) alternators offer significant savings over new units and often carry a comparable warranty.
💡 Top tip: Before replacing the alternator, test it properly. A simple multimeter test should show 13.8–14.4 volts at the battery with the engine running. Sometimes the issue is just a worn drive belt slipping on the alternator pulley.
