What parts do I need for my alternator pulley replacement and how much do those parts cost?
When replacing an alternator pulley, it's not necessary to service all of these parts. However, it's important to consider their price and function in case they do require servicing in the future.
- Alternator pulley: This metal, circular component plays a crucial role in moving the tension belt. When worn or damaged, it can lead to malfunctioning of the alternator belt. Replacing an alternator pulley is essential for proper functioning of the alternator system.
- Tension belt: The tension belt is a vital part of the alternator system, providing the necessary tension for proper operation. If the alternator pulley fails, it can result in damage to the tension belt. Replacing the tension belt is crucial to ensure optimal performance of the alternator system.
We recommend purchasing these parts from MyMechanic. Reputable options are advisable for their reliability. However, recommended options may vary based on your vehicle's specific year, make, and model.

How will a mechanic replace my alternator pulley?
Although it's not mandatory to seek professional assistance for an alternator pulley replacement, it's highly advisable. Should you decide to do so, here's an outline of the steps your mechanic will follow to ensure a successful alternator pulley replacement:
- Disconnect the car battery: Prior to any work, your mechanic will disconnect the car battery to prevent any risk of electric shock from the charging system during the repair process.
- Loosen and remove the tension belt: Using an impact wrench, the mechanic will loosen and remove the tension belt, providing easy access to the alternator pulley and its bearings.
- Remove pulley bolts: Next, the mechanic will remove the bolts securing the old alternator pulley in place. In case of resistance, they may apply a lubricant such as WD-40 to ease the process.
- Remove and replace: Once the old pulley is removed, the mechanic will install the new one, ensuring each bolt is securely tightened. Then, they'll reattach the tension belt and reconnect the negative battery cables.
- Test run: To verify proper functionality and voltage output, the mechanic will conduct a test run. This allows them to check for any additional issues, particularly regarding battery drainage.
What happens if I don’t replace my alternator pulley?
Skipping regular maintenance inspections or neglecting to replace your alternator pulley at the recommended mileage can have serious consequences for your vehicle's operation. Here are some potential outcomes of a failed alternator pulley:
- Stalled car/car engine failure
- Increased stress on tension belt
- Additional damage to alternator system
- Battery draining problems
What is an alternator pulley?
Alternator pulleys play a vital role in the functioning of the alternator system by facilitating the movement of the tension belt and drive belt. Without the alternator pulley, these components cannot rotate, resulting in the inability to generate electricity needed to power your vehicle's electrical system.
There are three types of alternator pulleys:
- Solid pulley: This standard alternator pulley variant drives the alternator and typically requires replacement only if damaged, rusted, or worn.
- Overrunning alternator pulley (OAP): Featuring a one-way clutch mechanism, this pulley rotates in the overrun direction, reducing belt noises during engine shutdown and transmission shifting.
- Overrunning alternator decoupler (OAD): Constructed with special steel torsion springs, the OAD absorbs engine vibration and functions similarly to the OAP.
When should I replace the alternator pulley on my car?
The most common alternator pulley replacement symptoms are:
- Damaged timing belt: One obvious indication that your alternator pulley needs replacement is a damaged timing belt. If the alternator pulley isn't functioning correctly, it may lead to fraying and tears on the timing belt, as it fails to turn as required.
- Damaged alternator: While more challenging to detect, a malfunctioning alternator pulley can result in damage to the alternator itself. The inability of the alternator pulley to turn properly can cause the alternator belt to slip, potentially causing damage.
- Check engine light: A flashing or constant check engine or warning light is a common symptom of vehicle issues. In the case of a deteriorating alternator pulley, this light may resemble a car battery symbol or display the words ‘GEN’ and ‘ALT’.
- Unusual sounds: Chirping, squeaking, or squealing noises often indicate an alternator pulley in need of replacement. These sounds suggest that the pulley may be misaligned with the alternator belt or angled improperly.
- Burning smells: Two distinct smells signal a defective alternator pulley. The smell of burnt wires may indicate overheating of the alternator, while the smell of burnt rubber suggests possible damage or excessive heat to the alternator belt.
- Inconsistent exterior lights: Since the alternator pulley contributes to producing electricity for the vehicle, a faulty pulley can affect the operation of exterior lights and other electronic components in the car.
- Dead vehicle: Finally, a vehicle that fails to start is a clear indication of alternator issues. Before seeking professional assistance, inspect the alternator pulley and belt for any signs of damage or malfunction.
How often should an alternator pulley be replaced?
Inspecting alternator pulleys every 60,000 miles and replacing them every 120,000 miles is crucial to prevent potential damage to your car's alternator. A simple test involves disconnecting your battery to check for any signs of damage.
Additionally, faulty alternator belts and tensioners can accelerate the wear of alternator pulley bearings. Therefore, it's essential to adhere to regular vehicle maintenance schedules and promptly address any noticeable signs of wear.
Can I replace my alternator pulley myself?
If you're confident in your DIY skills, you can undertake an alternator pulley replacement yourself. However, keep in mind that this process involves several steps and requires a certain level of automotive repair knowledge. If you're unsure about your abilities, it's advisable to seek assistance from a licensed mechanic for the replacement of your alternator pulley.
FAQs
No, it's not advisable to drive with a damaged pulley as it can lead to various issues, such as the alternator belt dislodging or coming loose, resulting in a loss of electricity flow in your vehicle. Driving in this condition can cause your car to stall, especially in traffic, and may potentially lead to increased car insurance rates if an accident occurs. If your tensioner pulley or ASD pulley breaks while driving, it's crucial to pull over immediately and call for roadside assistance.
Several factors can contribute to a malfunctioning alternator pulley, including high belt tension and damage to auxiliary equipment. During the removal of the alternator pulley, visible abrasions can indicate the cause of failure, allowing for further investigation. It's essential to perform routine inspections every 60,000 miles to prevent potential complications.
Loud alternator pulleys can be both annoying and indicative of underlying issues in your vehicle's engine compartment. However, there are various reasons why an alternator pulley might produce noise, including incorrect sizing or design flaws.
