What does a belt tensioner do?

A belt tensioner keeps the serpentine belt tight. This ensures that all the accessories driven by the belt, like the alternator and power steering pump, operate correctly and efficiently.

How do I know if my belt tensioner needs replacing?

Common signs include a squealing noise from the belt area, especially on startup or when accessories are engaged, or visible wobbling of the tensioner pulley. If the tensioner fails completely, the belt can slip off.

Does this tensioner come with a new belt?

This Omix part is a replacement belt tensioner only. A new serpentine belt is not included and would need to be purchased separately if your belt also requires replacement.
