Alternators

Refine Results

What One is

It's a critical part of the charging system in a GM-brand vehicle.

What it Does

It turns mechanical energy -- more simply put, the movement of parts -- into electrical energy, or electricity. The electricity charges the vehicle's battery, powers its dash lights and instrumentation, runs its windows, electronics, steering system, and windshield wipers, and keeps other electrical systems working the way they're supposed to.

How it Works

The process starts with the engine, the serpentine belt, and the drive belts. They move a pulley, which spins a rotor shaft, which turns magnetic coils, producing a magnetic field. The resulting power is managed by a voltage regulator.

The Signs One's Failing

Unfortunately, no alternator is permanent. What generally causes one to go bad is broken-down parts, an overtightened belt, incompatible accessories being installed, or a jump-start gone wrong. Although there may be little to no warning when one does fail, you can look for symptoms lighting and electronics malfunctions, battery and alternator warning lights on the dash, a squeaking engine, a dead battery, and a burning odor around the battery or alternator. You may even notice an alternator fluid leak.

See any of these, and you should inspect the vehicle's alternator. Follow up by testing its charging system immediately. Replace any parts the results recommend.

When to Change One Otherwise

Take care of the job every 80,000 miles, at most every 150,000 miles. That means about every 7 years. Review your owner's manual's maintenance schedule for complete info. When you order a new one, though, get the genuine article.

Why Buy Genuine OEM

Your GM brand will have manufactured it compatible with your model specifically. That assurance, off-brands can't always give you.

Where to Order a GM Alternator Online

Our auto parts catalog has a wide selection, and at competitive prices often well below MSRP. Just be sure to browse with your model (Chevy Caprice, for instance) and model year (2014, 2015, 2016, or 2017, for example) filled in; it's the best way to find an alternator that fits quickly. You can even search by part number (e.g., 92254798), if you have one.

Buy one now, and we'll ship it anywhere that you live or work, nationwide. (We'll even confirm your VIN at checkout, so you can rest assured what you buy will be the right fit.) If your order's in stock, it can leave our warehouse in 24 hours. Out-of-stock alternators, however, generally go out in as few as 2-3 business days (up to 5 to 6 sometimes, but not often). Shipping options include ground and overnight, and local pickup may be available at our Biscayne Blvd. location in Miami FL. Returns are no problem, either; just get in touch with us to start the process. You can even cancel your order if you need to, before it's shipped from GM.

Of course, if you've got a question, you need buying advice from an expert, or a concern has popped up while shopping, our team of parts specialists is here to help. Feel free to contact us anytime.
