Information
Drive belt tensioner (Hydraulic Portion).
Hydraulic drive belt tensioner (poly V-belt) for Porsche Cayenne and Panamera models. Maintains correct accessory drive belt tension (alternator, power steering pump, A/C compressor, etc.), compensating for belt wear and stretch, reducing noise, and ensuring proper belt alignment. Manufactured to original Porsche factory specifications.
Fits:
Porsche 958 Cayenne S / GTS / Turbo 4.8L 2011 - 2016
Porsche 970 Panamera 3.6L 2011 - 2016
Porsche 970 Panamera S / GTS / Turbo 4.8L 2010 - 2016

• Position on Vehicle: Mounted in the accessory drive belt system on the front of the engine – the tensioner damps vibrations and maintains belt tension/position in the serpentine belt loop.
• Applications: Ideal for replacement when the original tensioner is showing signs of wear, belt noise appears, or during belt replacement to maintain proper belt tension and accessory drive reliability.
The drive belt tensioner plays a crucial role in ensuring proper tension, alignment, and vibration-free operation of the accessory belt. A worn or damaged tensioner can lead to belt squeal, misalignment, increased accessory wear, and even belt failure - potentially causing alternator, power steering, or air conditioning system failure. Replacing it with a new one ensures proper belt system operation and helps protect critical engine accessories.
When and why to replace:
• A noticeable squealing or chirping belt noise on engine start or under load.
• Visible wear, looseness or vibration in the belt tensioner or pulley.
• During replacement of the accessory drive belt as part of scheduled service.
• If the vehicle has high mileage and original tensioner shows aged performance.
• To restore quiet, consistent accessory drive performance and prevent unexpected belt or accessory failure.

Information
Power Steering Belt
This Power Steering Belt is an OE Match V-belt drive belt designed for Porsche 928 models equipped with power steering. It transfers power from the engine to the power steering pump.
Fits:
Porsche 928 1985 - 1995
for cars with power steering
Diagram ref no 20
The belt transmits rotational force from the engine to the power steering pump, enabling hydraulic pressure that assists steering. This reduces steering effort and improves control, especially at low speeds. Without a functioning belt, the power steering system will not operate correctly.
Function
• Drives the power steering pump via crankshaft pulley
• Maintains hydraulic pressure for assisted steering
• Ensures smooth and responsive steering operation
• Provides reliable power transmission under load
Over time, drive belts wear, stretch, or crack due to heat and continuous use. A worn belt can slip, reduce steering assistance, or fail completely -resulting in heavy steering and potential loss of control. Replacing the belt ensures consistent power delivery to the steering system and prevents unexpected failure.
When to replace
• Cracked, frayed, or glazed belt surface
• Squealing noise from engine bay
• Reduced or inconsistent power steering assistance
• Visible belt slack or wear
• During routine service or preventative maintenance
