Why Replace This Part?
Drive belts wear over time due to heat, vibration, pulley contact, age, tension changes, and engine bay conditions. A worn belt can crack, glaze, stretch, fray, squeal, slip, or fail completely. If the belt fails, driven auxiliary systems may stop operating correctly, which can lead to warning lights, charging faults, accessory issues, or vehicle breakdown. Replacing the belt helps restore dependable auxiliary drive performance.

• Belt squeal, chirping, or slipping is present
• The belt does not track correctly on the pulleys
• The alternator, pulleys, tensioner, or related components are being serviced
• Charging or accessory drive faults are present
• Preventative belt replacement is being carried out during scheduled maintenance
• The vehicle is undergoing Porsche 996 Turbo or 997 Turbo engine service.
Where it fits on the car
This drive belt fits within the engine auxiliary belt drive system on Porsche 996 Turbo and 997 Turbo models with air conditioning. It runs around the relevant pulleys according to the factory belt routing.

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
