Alternator fan / impeller housing strap. Porsche 993 turbo ❭ 99310625150
- Porsche 993 (911) TURBO 1994-96
- Porsche 993 (911) TURBO S 1994-97
- Porsche 914 (1970-1976)
Direct replacement alternator fan and impeller housing strap for Porsche 911 (993) models. This strap secures the alternator fan and housing assembly in place, ensuring proper alignment and reliable cooling performance. Built to OE specifications, it matches the fit and strength of the original part while offering excellent durability.
Fit:
Porsche 993 turbo - 1994 to 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
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.

- Porsche 911 1978-1989 3.3L Turbo (930)
The OE Match Alloy Alternator Fan Housing is a premium-quality replacement engine cooling component designed to securely mount the alternator and cooling fan while directing airflow across the air-cooled engine on compatible Porsche models. Manufactured to OE specifications for fit, strength and durability, this alloy fan housing restores the original cooling efficiency and appearance of the engine bay.
Fits:
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
- Porsche 911 1978-1989 3.3L Turbo (930)
Manufactured from high-quality cast aluminium alloy, the housing offers excellent structural rigidity, corrosion resistance and heat dissipation. Precision-machined mounting points ensure accurate alignment of the alternator and cooling fan, providing proper belt tracking and optimum airflow throughout the engine cooling system. It is ideal for restoration projects or replacing cracked, corroded or damaged original fan housings.
What This Product Does:
- Supports and positions the alternator and engine cooling fan.
- Directs cooling airflow over the engine cylinders and cylinder heads.
- Maintains correct fan and alternator alignment.
- Ensures proper drive belt tracking.
- Helps maximise engine cooling efficiency.
- Provides secure mounting for associated engine components.
- Restores the original appearance of the engine compartment.
- Forms an essential part of the air-cooled engine cooling system.
Symptoms Of Wear Or Failure:
- Cracks or fractures in the housing.
- Corrosion or oxidisation of the alloy.
- Misaligned cooling fan or alternator.
- Excessive fan belt wear or belt misalignment.
- Fan rubbing against the housing.
- Increased engine operating temperatures.
- Unusual noises from the fan assembly.
- Loose mounting points or damaged fixing threads.
- Visible impact damage.
- Poor engine bay appearance during restoration.
Why Replacement Matters:
- The alternator fan housing is exposed to constant engine vibration, high operating temperatures and repeated thermal expansion and contraction. Over time, the alloy housing can develop cracks, corrosion or damaged mounting points, affecting the alignment and efficiency of the engine cooling fan and alternator.
- A damaged fan housing can reduce cooling airflow, increase fan belt wear and place additional strain on the alternator and cooling fan assembly. In air-cooled Porsche engines, reduced cooling efficiency can contribute to elevated engine temperatures, which may affect reliability and long-term engine durability.
- Replacing a worn or damaged alternator fan housing restores the correct positioning of the cooling fan and alternator, ensuring efficient engine cooling and reliable accessory drive operation. The OE Match replacement provides factory-style fitment, high-quality cast alloy construction and exceptional durability, helping preserve the performance, reliability and authentic appearance of your Porsche.

This alternator fan / impeller housing strap is a high-quality replacement component engineered in stainless steel. This strap secures the alternator cooling fan or impeller housing in the engine bay of classic Porsche air-cooled vehicles, providing enhanced corrosion resistance and durability.
Fit:
Porsche 911 1965 - 1989
Porsche 911 (930) Turbo 1975 - 1989
Porsche 964 Turbo 3.3L / Turbo 3.6L 1991 - 1994

This OE Match strap secures the alternator cooling fan or impeller housing to the engine block or accessory mount, maintaining correct belt alignment, reducing vibration, and preserving the designed airflow path for the cooling system. Its robust stainless construction helps ensure that cooling performance and accessory alignment remain stable through many heating/cooling cycles and varying environmental conditions.
Installed between the fan housing and the engine accessory bracket, the stainless steel strap:
• Provides a rigid mounting point for the alternator fan/impeller housing
• Maintains accurate belt and pulley alignment
• Reduces the risk of strap deformation, corrosion, or fatigue
• Helps ensure consistent airflow distribution for engine cooling
The factory strap is steel and, over time, can be prone to corrosion, bending, fatigue, or surface degradation due to heat cycling and environmental exposure. These issues can lead to fan misalignment, belt wear, and reduced cooling performance. Upgrading to an OE Match stainless steel strap enhances reliability, resists corrosion, and improves longevity - ideal for engines used in daily driving, classic car tours, or restoration builds where long-term durability is important.
When to replace:
• Original strap shows corrosion, rust, or fatigue cracks
• Fan housing shows signs of misalignment or vibration
• During alternator, cooling fan, or accessory belt service
• When restoring or rebuilding the engine assembly
• Preventive upgrade to improve reliability
