How to Fix a Noisy Alternator

Is your alternator's bearing getting quite noisy to the point of being worrisome? Here's what you need to do in order to fix it.

An alternator is the car part that generates electrical power for the various components of the vehicle as part of the automotive charging system along with the car battery.

It's a lightweight part that's found near the front of the engine. It produces alternating current with the help of electromagnetism. With that said, let's drive right into why your alternator is noisy in the first place and what can be done about it.

Diving Deeper Into Alternator Bearing Noise

  • The Potential Complications: Your car's battery can be affected by a malfunctioning alternator. It can malfunction for a variety of reasons, including changes in climactic or weather conditions and the entry of dirt into the car part. What's more, alternators can also wear out over time. If you have a squealing alternator bearing, it can fill your heart with worry. Don't add stress in your life by leaving the reason for the noise in the dark. Check it out for yourself
  • A Failure of Bearings: Bearings failure is usually the reason why your alternator is noisy. The alternator works in a manner wherein all its moving parts will rotate in order to produce electricity. One of the parts is known as the bearing needle. There are several of these needles that help manage free spinning of the alternator's rotor within the stator. When they fail they make noise, hindering the spinning of the rotor and making it harder for your electrical components to run.
  • Reasons for Hindrance: The reasons for alternator bearing hindrances include dirt and heat accumulation around the alternator, resulting in a grinding noise. If you ignore the noise and just continue driving, this can lead to alternator failure, so make sure to do your due diligence when it comes to under-the-hood checkups and tune-ups. Prevention is better than the cure not only in bodily and mental health but also when it comes to vehicular health.
  • The Certainty Test: The certainty test involves jumpstarting your car then as soon as it starts, do away with the jumper cables. Unclip the jumper cables and see what happens, in other words. If your car's engine halts soon after then something is wrong with your alternator. Otherwise, if it continues to run, your battery probably requires charging.
  • Headlight Check: You can also do what's known as the headlight check. This involves starting the car and asking someone to check your headlights out. Maintain your vehicle in park mode then depress the accelerator pedal. If the headlights start becoming faint or stop working, your alternator might be the cause.
