If you ever hear growling or whining noises coming from under the hood, you could have alternator problems, which should be checked out by a professional ASAP. This growling or whining sound happens when the belt that turns the alternator's pulley becomes misaligned or rubs against the side of the pulley.
It requires a good deal of energy to crank the car's motor, and if a battery is not replenishing its power properly due to a faulty alternator, it will become drained and ineffective. You will hear a clicking noise while attempting to start the car, and the engine will have difficulty turning over.
The alternator has several bearings which allow the alternator's rotor to spin freely. If these bearings begin to fail, you will notice a loud whining noise, which will increase when you accelerate or the car is under heavier load.

The engine of the car makes a whirring sound when accelerating. The more you accelerate, the more the whirring increases. It's time to get your car in for a checkup! There might be a number of reasons for this, including a bad water pump, low levels of power steering fluid, and a bad air conditioner compressor.
Most alternators will last between 80,000 and 150,000 miles — or about seven years. However, your driving habits and the area where you live could wear it out prematurely.
While you can technically still drive with a bad alternator, it is not advised. This is especially true in newer vehicle models. This is because there is more electricity involved compared to an older model.
Alternators can go bad suddenly, or slowly over time. If your alternator is slowly going bad over time there are some warning signs you can look out for.
One of the most common problems you're likely to experience with an alternator is a failure in the bearings. There are needle bearings in the alternator that allow the rotor to freely spin inside the housing, and those bearings can break down over time as a result of exposure to heat and dirt.
What happens when alternator stops working while driving? The car tends to slowly lose power if the alternator has gone bad while the car is being driven. You'll notice the headlights start to dim shortly before the car loses power and dies.
Age and use-related wear is often the reason behind a dying alternator. Engine oil or power steering fluid leaking onto the car alternator can lead to its failure. Prolonged idling while using multiple electrical accessories can prematurely wear the alternator.
An effective method to determine whether it's your battery or alternator that's gone bad is to connect jumper cables from a running vehicle's battery to yours. After a few moments, try starting your vehicle. Once it's started, remove the jumper cables — if your engine stalls, your alternator has probably gone bad.
Alternators can average anywhere from $100 to $350, depending on the model. In most cases, costs will average between $350−400 for the alternator replacement if no other parts need to be changed. Add another $20 to $50 to your bill if the serpentine belt has to be replaced as well.
If your alternator fails when you're far from home, you can typically drive up to 200 miles on battery power alone. That's assuming your battery is in good shape and fully charged. Of course, it's best to get the alternator repaired or replaced as soon as you can.
A corroded or defective alternator diode will faultily continue charging the circuit even when the car off. This, in turn, will drain your car battery and cause the car not to start.
If the alternator begins to fail, the battery will no longer recharge while the engine is running. Here's how to tell if your alternator is bad. One of the most obvious signs is if the car dies after a jump start.
In general, it will take about two hours for you to replace an alternator on your own, though this could vary somewhat depending on your knowledge of car mechanics. If you take your car into a shop in order to have the alternator replaced, timing may vary somewhat, and you may have to leave the car for the day.
Your battery should be one of the first things on your checklist after installing a new car alternator. Any installation guide will say that you need to disconnect the battery before installing the new alternator.
Starting the car and using the radio, the on-board navigation system, the heated seats, power mirrors and windows and any other electrical equipment will decrease the alternator's longevity.
Loud squeaking or squealing noise while accelerating could mean there's a problem with your engine belt. It could mean the belt's loose or worn. Or it could mean that one of the belt's pulleys is starting to fail. Loud rumbling noise when accelerating might suggest there's a problem with your exhaust system.
Definitions of whirring. sound of something in rapid motion. synonyms: birr, whir, whirr. type of: sound. the sudden occurrence of an audible event.
When you hear a high-pitched squealing sound coming from under your hood, you may need to check your vehicle's serpentine belt for cracks and wear. Many cars have multiple belts, and each one will need to be checked to ensure they are in good working order.
