What is the alternator pulley?
Your car’s alternator is a crucial part of its charging system. It provides the battery, engine and electronic components with a constant source of power. The alternator receives power from the drive belt, which loops over the alternator pulley. The alternator pulley allows for the correct transfer of power from the drive belt to the alternator.

Alternator pulley problems are usually caused by damaged bearings. If the alternator pulley fails, it can stop the alternator from receiving the necessary power to function. This can deprive your car battery and electrical system of energy, causing it to stop working. Problems with the pulley can also cause damage to the drive belt, resulting in a much more expensive repair if the problem is ignored.
Symptoms of a damaged alternator pulley:
Loud grinding or squeaking noises – A failing alternator pulley will usually produce loud squeaking or grinding noises while you are driving.
Battery warning light – A failing alternator pulley can limit the amount of power passing from the alternator to the battery. The can cause the battery light to constantly stay on or turn on intermittently.

Difficulty starting your car – If the pulley completely fails, your car may not start. This happens due to the alternator being unable to deliver any charging power to car battery and the rest of the car.
Engine stops – cuts out while driving – When the pulley fails while you are driving, your car will be left running on only car battery power (this will usually trigger the battery warning light). Once the battery’s power is depleted, your engine will start to run rough, then cut out and stall. This can be a serious safety risk, especially if you are driving at higher speeds in in city traffic.
