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.
