GM Alternators

Refine Results
Your battery might start your car or truck, but your factory alternator is key to making everything run and stay running. A GM alternator is the most dependable way to ensure power can travel between your vehicle's battery and electrical systems. However, even the best of these can go bad with little or no warning. Everything from quality to your driving conditions and even the electronics you use can play a part in alternator failure. When should you replace your alternator? Look for the signs. A major one is outright electrical failure. Another is flickering headlights. Your car radio or entertainment system can become unreliable. You might smell burning when inspecting both your battery and alternator. Your alternator warning light could come on, and your engine could start squealing. However, you may not even see signs of alternator failure. You could, for instance, cause one with an incorrect jump-start. You could also accidentally overload your alternator while installing accessories. If your alternator leaks fluid or has an overly tight belt, bearing damage can result, meaning quicker wear and tear. You can sometimes even trace a dead battery back to alternator trouble. In this case, your electronics may have switched entirely from alternator power to battery power. So, if you've got a battery warning light on the dash or your headlights are weak, do an inspection and charging system test. When you should change your alternator is otherwise uncomplicated. The answer is at 80,000 to 150,000 miles, or every 7 years or so. You can get details from your owner's manual and its alternator maintenance schedule. The best alternator for the job is genuine GM. Order one today from our online auto parts counter. We'll have it out to you for your project in no time!
