- Maintains proper belt tension: the spring-loaded arm applies constant force to the accessory drive belt so it tracks and grips the pulleys.
- Absorbs belt vibration: helps dampen slack and shock as engine speed changes, reducing chatter and slip.
- Complete assembly: replaces the tensioner as a single unit for a straightforward swap.
A worn tensioner may show up as belt squeal or chirp, a rattle or knock from the tensioner, or a belt that slips or wears prematurely. If a failing tensioner is the cause, installing FT40350 restores proper tension; diagnose the noise first, since other components can produce similar symptoms.
