Applies constant, calibrated force to the serpentine belt, compensating for belt stretch and engine vibrations to prevent slip, squeal, and premature belt wear. Often catalogued as “tensioner element / accessory drive belt tensioner.”

Position on car: Front of engine, serpentine belt drive—bolts to the bracket/mount assembly.

Why & when to replace:
• Belt squeal, flutter, or visible tensioner wobble
• Rough/idling noises from the front of engine, or belt glazing
• During belt service or accessory repairs (alternator, A/C, P/S)

Replacing the unit restores correct belt tension and accessory reliability
