•   Accessory drive warning lights or charging issues
•   Tensioner damper oil leakage or visible wear
•   Belt coming off or tracking incorrectly.

When to Replace This Part
•   When replacing the drive belt if the tensioner is worn or noisy
•   If the belt tensioner damper is leaking or weak
•   If belt squeal, vibration or mis-tracking is present
•   During accessory belt system overhaul
•   When replacing idler pulleys, guide pulleys or related belt-drive components
•   If the tensioner has excessive movement or play
•   If the tensioner no longer maintains correct belt tension
•   When restoring the engine with correct Genuine Porsche OE parts.
