The OE Match Impeller Blade Fan Centre Support is a premium-quality replacement engine cooling component designed to securely support and locate the engine cooling fan impeller on compatible Porsche models. Manufactured to OE specifications for fit, strength and durability, this centre support maintains correct fan alignment, ensuring smooth operation and efficient airflow through the engine cooling system.
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-strength, precision-machined aluminium alloy, the fan centre support is engineered to withstand high rotational speeds, engine vibration and continual thermal cycling. Its accurately machined mounting surfaces and balanced construction ensure the cooling fan remains correctly centred, reducing vibration and promoting long-term reliability. Designed for direct OE-style installation, it integrates seamlessly with the original cooling fan assembly.
What This Product Does:
- Supports and locates the engine cooling fan impeller.
- Maintains correct fan alignment during operation.
- Ensures smooth, balanced fan rotation.
- Helps maximise airflow through the engine cooling system.
- Reduces vibration within the cooling fan assembly.
- Supports efficient engine temperature regulation.
- Restores factory cooling system performance.
- Forms an essential part of the engine cooling fan assembly.
Symptoms Of Wear Or Failure:
- Excessive vibration from the engine cooling fan.
- Whining or rumbling noises from the fan assembly.
- Fan wobble during operation.
- Premature wear of the fan bearings.
- Misalignment of the cooling fan.
- Reduced cooling efficiency due to improper fan positioning.
- Visible cracks or damage to the support.
- Corrosion affecting the mounting surfaces.
- Difficulty securing the cooling fan correctly.
- Accelerated wear of surrounding cooling system components.
Why Replacement Matters:
- The impeller blade fan centre support is subjected to continuous high-speed rotation, engine vibration and significant temperature fluctuations. Over time, wear, fatigue or corrosion can affect its ability to maintain the precise alignment required for smooth fan operation.
- A damaged or worn centre support can cause the cooling fan to run out of balance, creating excessive vibration, bearing wear and reduced airflow through the engine cooling system. If left unresolved, this can contribute to reduced cooling performance, increased stress on adjacent components and the potential for overheating.
- Replacing a worn or damaged fan centre support restores the correct positioning and stability of the engine cooling fan. The OE Match Impeller Blade Fan Centre Support is manufactured to OE standards using premium-quality materials, providing factory-style fitment, exceptional strength and long-lasting durability to help maintain efficient engine cooling and dependable Porsche performance.

Alternator Fans & Impellors for Effective Cooling and Long-Lasting Performance
Alternator fans and impellors are essential cooling components that regulate the temperature of the alternator or generator during operation. As the alternator produces electrical power, it generates heat—making efficient airflow and cooling critical for maintaining optimal charging performance. These fans are engineered to draw air through the alternator housing, prevent heat buildup, and protect sensitive internal components from thermal stress.
What Alternator Fans / Impellors Do
Alternator fans and impellors perform several essential
functions:
- Direct
airflow across the alternator, reducing heat and extending component
life
- Maintain
consistent charging performance by preventing overheating
- Protect
internal bearings, rectifiers and windings from thermal damage
- Support
high-output alternators that run under heavier electrical loads
- Improve reliability in both standard and performance-oriented engines
Whether you are maintaining a classic model or upgrading a modern performance vehicle, an effective cooling fan is key to alternator longevity.
Why Alternator Fans & Impellors Fail
Despite being robust components, alternator fans can fail
over time due to mechanical stress, environmental exposure and vibration.
Common causes include:
- Metal
fatigue from continuous heat cycles
- Corrosion
due to moisture, dirt and road contaminants
- Cracked
or bent blades from debris strikes or worn mounting surfaces
- Loose
fittings causing imbalance and vibration
- Wear from high-output alternator upgrades that exceed the original cooling capacity
Faulty or weakened fans result in reduced airflow, causing the alternator to run hotter and less efficiently.
Why You Should Replace a Worn Alternator Fan / Impellor
A failing alternator cooling fan can lead to serious electrical system issues. Without proper airflow, the alternator may overheat, reducing charging performance and accelerating wear on internal components. Replacing the part with a high-grade, precision-built alternative engineered to match original performance standards ensures reliable cooling and prevents premature alternator failure.
Benefits of replacement include:
- Restored cooling efficiency and airflow
- Reduced alternator temperature under load
- Prevention of internal overheating and electrical faults
- Enhanced durability and component lifespan
- Improved reliability for daily and performance driving
A quality alternator fan is a cost-effective safeguard against much more expensive charging system repairs.
