FAQ:

Q: How much does it cost to replace a tensioner pulley?

A: Once that pulley is damaged or loose, then you are going to have some issues with your car’s performance. You will pay somewhere between $125 and $380 to have your tensioner pulley replaced. The labor should run between $45 and $155, while parts can cost as little as $85 or as much as $225.

Q: What are the signs of a bad belt tensioner?

A: The most common symptom of a bad or failing drive belt tensioner is noise from the belts or tensioner. If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started. It is also possible for the tensioner pulley or bearing to wear out, in which case the vehicle will produce a grinding noise from the pulley.

Q: When to replace serpentine belt tensioner?

A: Typically automobile experts advise a serpentine belt replacement or even a serpentine belt tensioner replacement once every three or four years, or after every 36,000 to 48,000 miles. This helps guard against unexpected belt failure which can leave you stranded and severely damage other engine components.

Q: Is the idler pulley and tensioner pulley the same?

A: The physical difference between an idler pulley and a tensioner pulley is a simple adjustable bolt. Tensioner pulleys are mounted on this bolt, and idler pulleys are not. They also differ in purpose. Idler pulleys spin in order to move belts to different places.
