Shopping for Alternator

Alternator Shopping Info

What Is an Alternator?

The vehicle’s alternator is essentially a built-in charger for the vehicle’s battery. It’s also an onboard generator that powers electrical components while the vehicle is moving. It’s typically found in front of your vehicle’s engine because it draws mechanical energy from the engine through a belt attached to the crankshaft.

It converts mechanical energy into electrical energy and sends it to the components that need it, like the battery.

Why Shop for Alternators at CarParts.com

You don’t have to live with a faulty alternator because you can get a replacement without having to break the bank.
