As you know, your car battery helps your car, truck or SUV start. Your original GM alternator is designed to keep all the parts running as they should. Do you think it's time to replace your alternator? Whether you choose to purchase a brand-new one or one that has been remanufactured, they all have the same functions.

Your alternator can fail due to a bad jump-start, accessory install, or age. There are some warning signs you can watch out for, which include flickering headlights or a burning smell. Some worst-case scenarios include a dead car battery. Most maintenance schedules recommend replacing the alternator every seven years or every 80,000 to 150,000 miles, depending on your driving habits. Remember to check your vehicle's owner manual for more information.
