What does a serpentine belt tensioner do?

The serpentine belt tensioner keeps the correct amount of pressure on the serpentine belt. This ensures the belt grips the pulleys properly so that components like the alternator, power steering pump, and A/C compressor can operate efficiently.

How do I know if my belt tensioner needs replacing?

Common signs of a failing tensioner include a squealing noise from the belt, especially on startup or when accessories are engaged, excessive belt vibration, or visible damage to the tensioner pulley or arm. If the belt is loose or has come off, the tensioner is likely the cause.

Does this tensioner come with a new belt?

This part is for the belt tensioner assembly only and does not include a new serpentine belt. You will need to purchase the belt separately if your belt also requires replacement.
