This tensioner helps maintain the correct tension and routing of the accessory (serpentine) drive belt, which powers multiple engine-driven components such as the alternator, air conditioning compressor, and other auxiliary systems. By applying consistent force to the belt, the tensioner reduces slack, prevents belt slip, and supports smooth belt operation under varying engine loads and temperatures.
Fits:
Porsche 958 Cayenne 3.0L DIESEL 2011 - 2018
Porsche 970 Panamera 3.0L DIESEL 2012 - 2016
Porsche 95B.1 Macan 3.0L TDI 2014 - 2018

Application:
Accessory drive belt tensioner assembly - installed in the front engine accessory drive system to control belt tension and alignment.
Function:
• Applies and regulates tension to the accessory drive belt
• Maintains proper belt alignment over pulleys
• Reduces belt chatter and premature wear
• Helps ensure reliable operation of belt-driven accessories
A worn or weak belt tensioner can lead to belt slip, increased noise (squeal or chirp), uneven belt wear, and reduced accessory performance. Replacing a failing tensioner restores proper tension control and helps prolong the life of the belt and pulleys - improving reliability and reducing the risk of accessory drive failures.
Replace the tensioner if you notice:
• Squealing or chirping from the belt area
• Visible belt wear or fraying
• Belt slipping under load
• Rough or noisy pulley bearing movement
• During routine accessory belt or tensioner service intervals

OEMatch Belts / Tensioners / Rollers — Fit, Function, Confidence
These belts, tensioners and rollers control engine timing and auxiliary drives on Porsche models and are commonly replaced during major services and engine rebuilds to restore precise operation and reduce the risk of future failures. Many owners search for genuine or OEM belts; OEMatch offers compatible alternatives engineered to match original-spec dimensions and tolerances for common Porsche applications.
- Timing belts and cambelts
- Auxiliary and serpentine belts
- Tensioner assemblies and hydraulic tensioners
- Idler and guide rollers
- Complete timing kits
Understanding OEMatch Belts / Tensioners / Rollers
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original belts, tensioners and rollers.
OE (Original Equipment) refers to parts matching original specifications for the belts, tensioners and rollers and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM belts, tensioners and rollers engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. OEMatch maintains a wide Porsche-focused catalogue and supports vehicle maintenance with thousands of cross-references and a continuing programme of new part development to help keep Porsche vehicles on the road.
Benefits Include
- Restored timing precision after rebuilds or major services
- Reduced risk of belt slip, noise and bearing failures
- Improved reliability for high-temperature and high-mileage applications
Why Belts / Tensioners / Rollers Wear and Fail
- Ageing rubber and heat exposure causing cracks or loss of flexibility
- Worn bearings in rollers or tensioners generating noise and vibration
- Loss of correct tension leading to slippage or timing misalignment
- Contamination from oil or coolant degrading belt materials
The Importance of Replacing with OEMatch Belts / Tensioners / Rollers
Replacing belts, tensioners and rollers during an engine rebuild or scheduled maintenance restores correct timing relationships, reduces the chance of catastrophic engine damage and supports long-term engine reliability on Porsche models. Using refreshed tensioners and rollers alongside new belts helps ensure even loading, quieter running and consistent operation across the rev range, protecting valves, pistons and ancillary drives.
Advantages
- Parts selected for Porsche applications and original-spec dimensions
- Complete kits available to simplify rebuilds and avoid mixing old and new components
- Options covering timing and auxiliary systems to match common service requirements
