The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.

This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies.
