Buick Alternator Guides

When you turn the key of your Buick, the battery provides power to the starter, which then starts the engine. If you have a good battery and the vehicle is still hard to start, it may indicate a problem with the Buick alternator. Within this device are three separate circuits that generate electrical power. When one of these circuits fail, the total power produced by the Buick alternator will be greatly reduced. When this happens, the battery will be used to a greater degree by the accessories in the vehicle, which will lower the current available for starting. Eventually the remaining circuits will stop functioning, and at this time, it will be necessary to replace the Buick alternator. On our website, the intuitive user interface makes it easy to find the perfect replacement for your vehicle. Our Buick alternator is manufactured to meet the original specifications and comes with a full warranty from the manufacturer. Before installing the new unit, disconnect the negative wire from the vehicle to avoid electrical damage. Find the location of the old Buick alternator, and determine how to remove the belt that drives it, usually by loosening an adjustment bolt on the part itself, or by relieving the pressure of the tensioning pulley on a serpentine system. While installing the new Buick alternator, be sure to tighten all bolts properly, then put the belt back on and reconnect the battery. Our online catalog has a wide range of other parts and accessories for your vehicle, as well, all at great prices. With our easy ordering and quick order processing, you will not have to wait long for your new Buick alternator to arrive.

Buick Alternator Buyer’s Guide

Summary

  • Buick has more than 100 years of experience in manufacturing cars and is currently the oldest automobile brand in the United States.
  • OEM Buick parts are manufactured by General Motors in its facilities found in the U.S. and other parts of the world.
  • You can use the OEM number of your alternator to search for a replacement part.
  • Getting a replacement alternator from a reputable brand can guarantee that you will get your money’s worth.
  • Aside from a new alternator, you can also get a rebuilt or remanufactured replacement.
  • Depending on whether it’s new or remanufactured, you can get a replacement Buick alternator at around $20 to $350.

Buick is the oldest automobile brand in the United States today. And with more than 100 years of experience, Buick seems to have mastered the art of car manufacturing. However, despite the superior quality it can produce, no vehicle can actually last forever. That said, Buick automobiles may require replacement parts from time to time. One of them is the Buick alternator.

Who manufactures genuine Buick parts?

Since Buick is a brand owned by General Motors (GM), its genuine parts are either manufactured by GM here in the United States or outsourced from its several official suppliers around the world. GM has 120 facilities across the U.S. composed of assembly plants, components plants, battery plants, stamping plants, propulsion plants, parts distribution centers, and engineering campuses.

How to choose the right replacement Buick alternator

Just like the other Buick parts of your car, your Original Equipment Manufacturer or OEM Buick alternator won’t last forever. Constant exposure to road dirt, moisture, and extreme heat can cause this part to fail. Once it does, you should immediately search for the right replacement. Here’s how to find one:

Look for your alternator’s OEM number

It’s quite rare to not be able to find a replacement alternator using just your vehicle’s year, make, and model. But in case this happens, you can use the OEM number of your old Buick alternator, which can be found on the part itself. You can also call your dealership with your VIN and they will provide it for you.

Get one that’s made by a reputable brand

If you’re looking for an OE replacement instead of an OEM alternator, make sure you get it from a trusted brand. This applies to your car’s other old Buick parts as well. Doing this can guarantee you are replacing your old component with a product that’s made to last, ensuring value for your money.

Rebuilt versus remanufactured alternator

Unlike other car components, you don’t have to purchase a new replacement alternator every time. There are actually other options like getting a rebuilt or a remanufactured alternator. In a rebuilt alternator, the faulty components are swapped out for new ones before the unit is reassembled. A remanufactured alternator, on the other hand, goes through a more rigorous process where it’s cleaned, disassembled, and sometimes reengineered to ensure that it can perform the same as before or even better.

How much does an alternator replacement cost?

You can find both new and remanufactured Buick alternators on CarParts.com. The starting price of a remanufactured replacement alternator is around $20 and can go as high as $300. When it comes to a new replacement Buick alternator, the price falls anywhere between $60 and $350. Of course, these prices may vary depending on your vehicle’s year, make, and model.

Use our website’s vehicle selector to ensure that your search results will be limited to alternators that are compatible with your ride. For example, if you have a 2003 Buick Rendezvous, plugging in your vehicle’s “YMM” in the selector can help you quickly find a replacement 2003 Buick Rendezvous alternator.

6 Signs of a Bad Alternator
6 Signs of a Bad AlternatorAlternator operation depends on a phenomenon called electromagnetic induction. When the engine is running, the drive belt turns a pulley on the alternator. That pulley causes the rotor inside the alternator to spin, which, in turn, creates a magnetic field that induces an electrical current in the alternator’s stator windings.
