Alternator fan / impeller housing strap.
Genuine Porsche alternator fan / impeller housing strap for 911 (993). Ensures secure fit, proper alignment, and reliable cooling performance.

Fit:
Porsche 993 Turbo 1994 - 1997

Diagram ref no 6

Location: Engine bay, securing the alternator fan / impeller housing  

What this product does:
•  Holds the alternator fan and impeller housing firmly in place
•  Ensures proper cooling airflow through the engine
•  Maintains alignment of the fan assembly to avoid vibration or damage

Over time, the original strap may stretch, corrode, or lose strength, reducing its ability to hold the housing firmly in place. A failing strap can cause the fan assembly to loosen, resulting in noise, vibration, or poor cooling performance. Replacing it restores secure fitment and proper tension, ensuring your Porsche’s cooling system continues to operate efficiently.

What this product does:
•  Holds the alternator fan and impeller housing firmly in place
•  Ensures proper cooling airflow through the engine
•  Maintains alignment of the fan assembly to avoid vibration or damage

With age, the original strap can weaken, stretch, or corrode, making it less effective at securing the housing. If it fails, the fan assembly may loosen, leading to unwanted noise, vibration, or reduced cooling efficiency. Replacing the strap ensures a secure fit and proper tension, keeping your Porsche’s cooling system performing as intended.
