Serpentine Belt Noise
One of the first and most obvious signs that you might need serpentine belt replacement is an unusual noise. When the belt is slipping it will make a squealing sound. If it is chirping it typically means there’s a misalignment of an accessory drive pully.
What Does A Serpentine Belt Do?
The serpentine belt is the way that your vehicle’s vital components get the power they need from the engine. It is a long winding, snaking belt that winds it’s way around the engine bay to power your power steering pump, alternator, water pump, and air conditioning.
When Do Serpentine Belts Need To Be Replaced?
Today’s serpentine belts are made to last and will usually make it to 60,000 or even 100,000 miles. Some vehicle manufacturers install self-tensioning mechanisms which might need servicing. Other systems may require manual adjustment to stop the noise and function properly.
How Long Does It take To Replace A Serpentine Belt?
For professional automotive technicians with the right tools and training the replacement of a serpentine belt usually takes about 30 min to an hour. This time varies by the make, model, and year of vehicle that you’re driving as some take longer than others.
Serpentine Belt Replacement Cost
Depending on the make, model, and year of your vehicle the cost of serpentine belt replacement will run somewhere between $60 to $200. High performance or larger trucks will require more robust serpentine belts and will typically be towards the higher end of the cost spectrum. If your vehicle has completely stopped running you will also have to consider the cost of getting your vehicle towed to the shop.
