We stock alternator pulleys that can be used to replace faulty parts without replacing the entire alternator, ensuring your car battery and other electrical consumers — like the lights, heating, and fans — can all do their job properly. Not sure which is the right type for your car? Enter the make and model into the tool above and we'll show you the most suitable pulleys for your vehicle.
The crankshaft in your car's engine is connected to the alternator by a serpentine belt and several pulleys, including the alternator pulley. When the engine is running, it turns the crankshaft, which in turn runs the belt through the pulleys. The alternator pulley spins, turning the magnetic rotor inside the stationary stator assembly, which the alternator then turns into a direct current that is used to power your car's battery and other electrical systems.
Without a correctly functioning alternator pulley, the alternator won't be able to produce this charge, which could lead to a total failure to start. So, if you suspect an issue with the pulley, it's important to get it fixed as soon as possible.
