Designed as a comprehensive service and preventative maintenance solution, this kit includes the essential components required to restore correct auxiliary drive belt operation, helping maintain consistent belt tension, smooth pulley movement, and reliable accessory performance under both everyday and high-performance driving conditions.
The drive belt system on the Porsche 718 2.5L turbocharged engine is continuously exposed to heat cycles, vibration, and mechanical load. Over time, wear to the tensioner mechanism, pulley bearings, or belt itself can lead to noise, belt slip, reduced efficiency, or potential component failure.
Replacing the tensioner lever, pulley, and belt together helps ensure long-term reliability and proper operation of critical engine-driven accessories.
This kit is ideal for scheduled servicing, preventative maintenance, or resolving common symptoms such as belt squeal, pulley noise, or worn tensioner operation on Porsche 718 S and GTS models.
Engineered for precise fitment and dependable performance, this kit helps maintain correct belt alignment and smooth accessory drive function for road and performance applications alike.

Diagram Ref No 5.
This belt is used on selected Porsche 924S and 944 four-cylinder engines and is a critical component of the engine timing system.
What This Part Does / Functions
• Synchronises camshaft and crankshaft rotation
• Ensures correct valve timing during engine operation

Replacing the timing belt with a Genuine Porsche OE cam belt helps maintain correct engine timing and supports reliable operation of the classic Porsche 924S / 944 engine. It is strongly recommended to inspect or replace related tensioners, rollers, balance shaft belt and water pump components during timing belt service.
When to Replace This Part
• During scheduled timing belt service
• If the belt is cracked, worn, frayed or glazed
• If the belt has been contaminated by oil, coolant or debris
• If the timing belt age or mileage is unknown
• When recommissioning a stored Porsche 924S or 944
• During camshaft, front engine seal, tensioner or roller replacement
• When replacing the balance shaft belt or water pump
• If timing belt noise, tracking issues or tension problems are present.
Where It Fits on the Car
This belt fits on the front of the engine, within the camshaft timing belt system. It runs between the crankshaft and camshaft timing pulleys and is protected by the timing belt covers.
