What parts do I need for a drive belt tensioner replacement and how much do they cost?
Verify with your mechanic or refer to the manufacturer’s specifications in your owner’s manual for the exact parts required. However, typically, here's a breakdown of what you'll need to replace your car's drive belt tensioner:
- Serpentine belt: This is a long rubber belt that transfers power to the engine accessories—the alternator, power steering pump, air conditioning compressor, and water pump. It connects the engine crankshaft on its exterior to the engine accessories.
- Tensioner: The drive belt tensioner is a pulley that keeps constant tension on your serpentine belt to allow various engine accessories to function.
- Pulley: A tensioner pulley applies the proper pressure and helps keep the belt tensioned and aligned. In this system, the tensioner pulley is spring-loaded to maintain the appropriate tension and alignment of the serpentine belt.
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.
If you're considering replacing the serpentine belt or the drive belt tensioner, opting for OEM parts might be beneficial. Although they tend to be pricier, OEM parts are tailored precisely to fit your vehicle's make and model. Both the serpentine belt and drive belt tensioner need to match the correct length and width for your car to function properly. With OEM parts being exact replicas of the original components in your engine, you can avoid dimension issues and potential malfunctions.
You can buy drive belt tensioners from MyMechanic. To ensure compatibility, refer to your vehicle’s owner's manual for specific details regarding the tensioner you need.

What happens if I don’t replace my drive belt tensioner?
Depending on the extent of wear and tear on your tensioner, there's a possibility that the belt could completely dislodge. This would result in the loss of power for components dependent on the serpentine belt, such as the air conditioner, alternator, smog equipment, water pump, and power steering. To avoid the risk of getting stranded on the side of the road due to a breakdown, it's crucial to promptly replace your drive belt tensioner if it's not functioning correctly.
What is the drive belt tensioner?
A drive belt tensioner is a component consisting of a pulley mounted on either a spring mechanism or an adjustable pivot point. Its purpose is to maintain constant tension on the serpentine belt, ensuring it remains taut on the crankshaft pulley. The serpentine belt wraps around various engine components, including the alternator, power steering pump, water pump, and air conditioning compressor. This tension allows the belt to effectively drive these engine components while the vehicle is in operation.
How do I know when my drive belt tensioner needs replacing?
Squeaking and grinding noises while the engine is running, or even squealing when you start your car, are key indicators that your drive belt tensioner may need replacement.
Other common symptoms of a bad drive belt tensioner include:
- Unusual belt wear
- Belt-driven accessories fail (alternator, A/C compressor, etc.)
Keep in mind: The drive belt tensioner plays a crucial role in your vehicle, ensuring that the serpentine belt remains properly tensioned to power your car's accessories. If the tensioner malfunctions, you'll lose essential functions in your vehicle.
How often does the drive belt tensioner need to be replaced?
While there's no set lifespan for a drive belt tensioner, it's advisable to have it inspected during routine maintenance checks for early detection of any issues. Typically, a drive belt tensioner lasts between 40,000 to 70,000 miles or 4 to 5 years. It's important to note that when replacing the tensioner, other components like pulleys and the serpentine belt may also need to be replaced.
Can I replace my drive belt tensioner myself?
Replacing your drive belt tensioner is not as straightforward as some other car components, but if you have automotive experience, you may be able to tackle it yourself. Many tensioners are readily accessible and attach to the engine with a single bolt. To replace it, you'll need to remove the serpentine belt and the retaining bolt, take out the tensioner, and install the new one. However, if you're not comfortable with this process, it's best to schedule an appointment with your local mechanic and let a professional handle it.
