Alternators & Electrical Systems

While your engine is running, the alternator supplies electricity to your systems and recharges your battery. Keep it running smoothly with regular electrical and charging system diagnostic checks from our Quick Lane® experts. If necessary, we can even replace your vehicle’s alternator.

Estimated Time: 1 hour


How often should I service my alternator?

Alternators can last anywhere from 50,000-150,000 miles. Check your owner's manual for the service schedule recommended for your vehicle. There's more than one sign that it's time to come in for service: dim or flickering interior and exterior lights, odd noises, a drained battery, and, of course, your check engine light.

We’re open after work. And this weekend.
