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

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.

High-Quality Alternator Fan Housings & Fan Straps for Secure Mounting and Optimal Cooling
Alternator fan housings and fan straps are essential components that help stabilise the alternator cooling system while ensuring efficient airflow around the alternator or generator. The fan housing (or shroud) directs cooling air, while the fan strap keeps the housing firmly mounted—ensuring the alternator receives consistent airflow to regulate temperature, protect internal components and maintain stable charging performance.
These components are especially important in performance-focused and air-cooled engines where airflow direction and alternator cooling efficiency are critical to reliability.
What Fan Housings & Fan Straps Do
Fan housings and straps perform several vital functions:
- Securely support and position the alternator fan assembly
- Direct
airflow to cool alternator internals and stabilise temperature
- Prevent
vibration and movement under engine load
- Maintain
correct belt alignment for efficient charging performance
- Protect surrounding components from heat exposure and debris
Together, the housing and strap form the structural backbone of the alternator cooling system.
Why Fan Housings & Fan Straps Commonly Fail
Because these components are exposed to engine heat,
vibration and constant tension, they can degrade over time.
Common failure
points include:
- Metal
fatigue or cracking from heat cycling
- Corrosion
caused by moisture, dirt and road contaminants
- Stretching
or loosening of straps leading to poor support
- Warped
or damaged housings affecting airflow
- Vibration-induced
wear especially in performance or high-rev environments
- Incorrect belts or over-tightening placing stress on the mounting system
A damaged housing or weakened strap can reduce airflow efficiency and cause alternator overheating or misalignment.
Why You Should Replace Worn Fan Housings & Straps
A compromised fan strap or housing can lead to reduced
cooling performance, alternator misalignment and eventually component failure.
Replacing them with precision-engineered, high-quality alternatives built to
match original performance standards ensures:
- Stable alternator mounting and reduced vibration
- Correct airflow direction for effective cooling
- Protection of internal alternator components
- Improved belt alignment and charging efficiency
- Long-term durability and peace of mind
Whether restoring a classic model or maintaining a high-performance engine, reliable fan housings and straps are essential for protecting the charging system.
