Questions drivers ask
How do I know if it is the alternator or the battery?
A weak battery may struggle to start the car, while a failing alternator often lets the battery drain as you drive. Warning lights and dimming lights can point to the alternator. Ask the shop to test both the battery and the charging system before you agree to a replacement.
Is a rebuilt alternator OK?
Many drivers choose rebuilt alternators because they cost less than new ones. They are common at independent shops. Ask what warranty comes with the part and get it on your written estimate.
How long does an alternator last?
It depends on the vehicle, how you drive and the conditions the engine runs in. We can't give a fixed lifespan. Check your owner's manual and ask the shop about the condition of your current part.
