Why Alternator replacement is so important.

Without some key electrical parts, your engine wouldn't be able to stay running. Your Chevrolet K20 alternator is powered by the rotation of the crankshaft thanks to a belt that connects pulleys on both parts. Inside that alternator, a constant supply of current for your car or truck is generated as a pair of metal claws and brushes spin around a coil; creating a powerful electromagnetic field. The energy from your alternator continuously charges the battery, and at the same time distributes current to the interior electronics, lights and turn signals, and any other electronic part on your Chevrolet K20.
