What parts do I need for my idler pulley replacement and how much do those parts cost?
You can check your owner’s manual or ask your mechanic for precise parts, but these are the main things you need:
- Idler pulley: This is the main component that needs to be replaced. It is responsible for guiding and maintaining tension in the drive belt. On its own, an idler pulley costs around $15 to $100.
- Drive belt: It is advisable to inspect the drive belt during the idler pulley replacement and replace it if it shows signs of wear or damage. Drive belts can cost anywhere from $20 to $100.
Pro tip: Consider purchasing a combined idler pulley and belt kit. These usually cost from $50 to $150.
You can buy idler pulley parts for your car from auto parts stores like AutoZone, NAPA Auto Parts, and Advance Auto Parts, or from online retailers such as Amazon and RockAuto. Three of our recommended brands for idler pulley parts are Dayco, Gates, and ACDelco, but the best parts for your vehicle will depend on its year, make, and model.
Should I buy an OEM or aftermarket idler pulley?
When replacing your idler pulley, both the OEM and aftermarket options have their pros and cons. While choosing an aftermarket idler pulley may save you more money, OEM idler pulleys tend to offer greater long-term reliability.

How will a mechanic replace my idler pulley?
When you take your car in for a faulty idler pulley diagnosis and replacement, the mechanic will usually take these following steps:
- Disconnect the battery
- Spin the pulley to see if can guide the belt
- Loosen the bolts around the old pulley and remove it
- Compare the old and new pulleys to ensure they match up
- Place the new pulley and tighten the bolts
- Reconnect the battery
A mechanic will inspect your drive belt alongside your idler pulley. If the pulley is broken, it’s highly likely that the drive belt could have been damaged as well.
Pro tip: It can also be helpful to get your mechanic to check your tensioner pulley, belt tension, and timing belt during an idler pulley replacement.
What happens when your idler pulley goes bad?
If the idler pulley breaks, it can lead to a loss of power in multiple systems since the drive belt won't be able to continue spinning. Failure to address this issue can result in the wearing down of the drive belt and the loss of essential engine-driven systems, such as the alternator, power steering pump, or air conditioning compressor.
What is an idler pulley?
Your car’s idler pulley plays a crucial role in guiding and aligning the drive belt, also known as the serpentine belt. This drive belt connects your car’s engine to various systems in your vehicle, including the power steering, alternator, water pump, A/C compressor, and alternator.
How do I know if my idler pulley is bad?
The most obvious sign that your idler pulley, or drive belt as a whole, needs to be replaced is a loud squealing, squealing, or chirping noise coming from the engine. Other signs include:
- Your check engine light comes on
- Your power steering is not working like it’s supposed to
- Your engine stalling or overheating
If you notice any of these issues, you’ll want to bring your car to a mechanic right away.
How often should the idler pulley be replaced?
Your idler pulley should be replaced every 50,000 to 100,000 miles because it gets worn out over time and repeated use.
Keep in mind: Often, idler pulley replacements coincide with a serpentine/accessory belt replacement.
Can I replace my idler pulley myself?
Even if you have auto repair and DIY skills, it’s not recommended that you try to replace an idler pulley on your own. The job involves the removal of critical timing components and knowledge of internal engine components, making it a complex procedure.
Given this complexity, it’s best to visit a reputable auto shop and let a trained mechanic handle it.
