Belts / Tensioners / Rollers

The Genuine Porsche Belt Tensioner Damper is an original equipment auxiliary drive system component designed to absorb vibration and stabilise the movement of the drive belt tensioner on compatible Porsche models. Manufactured to Porsche's exact specifications for fit, damping performance and durability, this precision-engineered damper helps maintain consistent belt tension, reducing belt oscillation and ensuring the reliable operation of engine-driven accessories such as the alternator, air conditioning compressor, power steering pump and water pump where applicable.

Fits:

• Porsche 957 Cayenne 3.0L Diesel 2007-10
• Porsche 958 Cayenne V6 3.0L Diesel (245Hp) 2010-17 

• Dampens movement of the auxiliary drive belt tensioner.
• Maintains consistent drive belt tension.
• Reduces belt vibration and oscillation.
• Helps prevent belt slip during acceleration and load changes.
• Protects the auxiliary belt and tensioner assembly from premature wear.
• Supports reliable operation of engine-driven accessories.
• Restores factory drive belt damping performance.
• Forms an essential part of the engine auxiliary belt drive system.

• Excessive movement of the belt tensioner.
• Auxiliary drive belt vibration or flutter.
• Squealing or chirping noises from the drive belt.
• Rattling noises from the front of the engine.
• Premature auxiliary belt wear.
• Belt slipping under load.
• Visible hydraulic fluid leakage from the damper (where applicable).
• Cracked or damaged damper housing or mounting points.
• Inconsistent operation of engine-driven accessories.
• Premature failure of the belt tensioner assembly.

• The belt tensioner damper is subjected to constant engine vibration, rapid changes in belt load and continuous movement throughout engine operation. Over time, the internal damping mechanism can wear or lose effectiveness, while seals and mounting components may deteriorate due to heat and age.
• A worn tensioner damper can allow excessive belt movement, increasing the risk of belt slip, noise and premature wear of the auxiliary belt, tensioner and driven components. If left unresolved, it can lead to accessory drive failure and unexpected vehicle breakdown.
• Replacing a worn or faulty damper with a Genuine Porsche component restores correct belt tension control and ensures smooth operation of the auxiliary drive system. Manufactured to Porsche's exact engineering standards, the Genuine Porsche Belt Tensioner Damper provides factory-correct fitment, exceptional durability and dependable long-term performance, helping maintain engine reliability, accessory efficiency and the driving confidence expected from your Porsche.

• Maintains the correct tension on the auxiliary drive belt.
• Reduces belt vibration and movement.
• Ensures smooth operation of the serpentine belt system.
• Supports efficient operation of engine-driven accessories.
• Minimises belt slip and premature belt wear.
• Maintains correct belt alignment.
• Restores factory belt drive performance.
• Forms an essential part of the auxiliary belt drive system.

• Squealing or chirping noises from the auxiliary belt.
• Rattling or knocking from the tensioner assembly.
• Belt vibration or excessive movement.
• Uneven or accelerated belt wear.
• Belt slipping during engine operation.
• Rough or noisy tensioner bearing.
• Visible movement or weakness in the tensioner arm.
• Damaged or seized tensioner roller.
• Auxiliary belt misalignment.
• Charging, cooling or air conditioning issues caused by belt slippage.

• The belt tensioner roller and damper operate continuously whenever the engine is running, maintaining the precise tension required for efficient belt operation. Over time, the roller bearing, damping mechanism and pivot components can wear due to constant rotation, vibration and heat, reducing their ability to control belt movement effectively.
• A failing tensioner assembly can allow the auxiliary belt to slip, vibrate or become misaligned, reducing the efficiency of critical engine accessories such as the alternator, water pump and air conditioning compressor. In severe cases, complete tensioner failure may result in the belt coming off, potentially leading to engine overheating, battery charging failure and loss of auxiliary systems.
• Replacing a worn or faulty belt tensioner roller and damper restores correct belt tension, smooth accessory drive operation and reliable engine performance. The OE Match replacement provides factory-style fitment, premium-quality bearings and durable construction, ensuring long-lasting performance and helping protect the entire auxiliary belt drive system.
