The drive belt tensioner lever and pulley assembly keeps the auxiliary belt under the correct operating tension. This allows the belt to reliably drive engine accessories such as the alternator, water pump, air conditioning compressor, and other belt-driven components depending on model specification.

Functions:
•  Maintains correct auxiliary drive belt tension
•  Guides the drive belt smoothly over the pulley system
•  Helps prevent belt slip, squeal, or misalignment
•  Supports reliable operation of belt-driven engine accessories
•  Reduces vibration and uneven belt movement
•  Helps protect the belt from premature wear
•  OE Match replacement kit for worn tensioner lever and pulley components

Why Replace This Part?
The tensioner lever and pulley are exposed to constant rotation, heat, vibration, and belt load. Over time, the pulley bearing can wear, the lever mechanism can weaken, and the tensioner may no longer hold the belt correctly. A worn tensioner or pulley can cause belt noise, slipping, charging problems, cooling issues, or accessory drive failure. Replacing the kit helps restore reliable belt tension and protects the auxiliary drive system.

When to replace
•  The auxiliary drive belt is slipping, squealing, or jumping
•  There is noise from the pulley bearing or tensioner area
•  The pulley has play, roughness, wobble, or visible damage
•  The tensioner no longer holds correct belt tension
•  The belt shows uneven wear, cracking, or glazing
•  The alternator, water pump, or air conditioning drive is affected
•  The drive belt is being replaced as part of major service
•  During engine accessory drive repair or preventative maintenance.

Where it fits on the car
This kit fits on the engine accessory drive system, where it tensions and guides the auxiliary drive belt. It is mounted at the drive belt tensioner position on the front/side of the engine, depending on the model and engine layout.

When to Replace This Part
•   When replacing the drive belt tensioner
•   When replacing the tension pulley or tensioner damper
•   If the original bolt is rounded, damaged, corroded or missing
•   If the bolt has been removed during belt-drive service and Porsche procedure requires replacement

The bolt secures the drive belt tensioner to its mounting point, allowing the tensioner to maintain correct auxiliary belt tension and belt alignment. A correctly fitted tensioner bolt is important for reliable belt operation and accessory drive performance.

Functions
•  Replaces the M8x60 drive belt tensioner bolt
•  Secures the drive belt tensioner assembly
•  Supports correct auxiliary belt tensioner mounting
•  Helps maintain belt alignment and stable belt operation
•  Used during drive belt, tensioner, pulley, or accessory drive service
•  Replaces damaged, corroded, stretched, worn, or missing original bolts
•  OE Match replacement fastening for Porsche belt drive repair.

Why Replace This Part?
Drive belt tensioner bolts are exposed to vibration, engine heat, belt load, and repeated service work. A worn, corroded, rounded, stretched, or damaged bolt may not provide correct clamping force and can compromise tensioner mounting. Replacing the bolt during tensioner or belt service helps ensure secure installation and reliable auxiliary drive operation.

When to Replace This Part
•  The drive belt tensioner is being replaced
•  The auxiliary drive belt is being serviced
•  The original bolt is corroded, rounded, stretched, damaged, or missing
•  The tensioner has been removed during engine service
•  Belt noise, poor belt tracking, or tensioner movement is being investigated
•  Preventative replacement is required during major service
•  The vehicle is undergoing Porsche accessory belt drive repair.

Where it fits on the car
This bolt fits at the drive belt tensioner mounting point within the engine accessory belt drive system. Exact position can vary depending on model, engine type, and belt layout.
