Belt Tensioner Roller And Damper. Porsche 957 Cayenne 3.0L Diesel 2007-10  ❭  95510236110

Belt Tensioner Roller And Damper. 
The OE Match Belt Tensioner Roller and Damper is a premium-quality replacement auxiliary drive belt component designed to maintain the correct tension of the serpentine belt on compatible Porsche engines. Manufactured to OE specifications for fit, performance and durability, this complete tensioner assembly combines a precision-engineered guide roller with a hydraulic or spring-loaded damping mechanism to ensure consistent belt tension under all engine operating conditions.  

Fits:

Diagram Ref No 1

Manufactured from high-strength steel and aluminium with a premium sealed bearing roller and durable damping mechanism, the assembly is engineered to withstand continuous engine vibration, high rotational speeds and demanding temperature conditions. Designed for direct OE-style installation, it integrates seamlessly with the original auxiliary belt drive system, helping to ensure reliable operation of engine-driven accessories such as the alternator, water pump, air conditioning compressor and power steering pump (where fitted).  

What This Product Does:

• 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.

Symptoms Of Wear Or Failure:

• 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.

Why Replacement Matters:

• 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.
