Air deflector alternator. 
The air deflector serves as an air baffle and provides optimal cooling of the cylinders. Bolts to the back of the alternator.

Fits:
Porsche 911 - 1975 to 1977
Porsche 911 SC - 1978 to 1983

Diagram ref no 10

Mounted on the rear of the alternator or alternator hub, bolting into or adjacent to the fan housing / ventilation shroud.

What it does:
Guides airflow from the cooling fan over the alternator and engine to maintain proper cooling
 Extends or positions the alternator hub correctly so pulleys are aligned and belt tension is correct
 Helps ensure consistent air circulation in the engine cooling system

Over time, deflectors or hub extensions can become warped, cracked, or corroded, compromising airflow and misaligning pulleys. A damaged deflector may lead to poor alternator cooling, reduced alternator lifespan, or belt misalignment. Replacing restores correct spacing, airflow direction, and ensures reliable alternator performance under all conditions.

About Air cooling parts

Air Cooling Parts – Engine Efficiency and Temperature Control for Porsche Vehicles

Air cooling parts are essential components designed to regulate engine temperature, ensuring your Porsche runs efficiently, safely, and at peak performance. These components manage airflow and heat dissipation within air-cooled engines, preventing overheating and maintaining consistent operating conditions.

At Design911, we offer a wide selection of genuine and high-quality air cooling parts for Porsche models including classic air-cooled 911s, 964, 993, and more. Our range includes fan assemblies, shrouds, ducts, pulleys, housings, and cooling tins, all precision-engineered for exact fitment and reliable thermal management. Every part is built to the same high standards as the original factory components, ensuring lasting performance and authenticity.

What Do Air Cooling Parts Do?

Air cooling components work together to keep the engine’s operating temperature stable by directing airflow across critical areas. Key functions include:

  • Cooling the engine cylinders and heads to prevent overheating.
  • Regulating airflow through fans, ducts, and shrouds.
  • Maintaining consistent engine performance under varying load and speed conditions.
  • Supporting mechanical efficiency and preventing thermal stress on components.

For Porsche’s legendary air-cooled engines, proper airflow and cooling performance are vital to achieving both longevity and smooth, balanced operation.

Why Do Air Cooling Parts Fail?

Over time, air cooling components can degrade due to exposure to heat, vibration, and environmental wear. Common failure causes include:

  • Cracked or warped shrouds and ducts from thermal stress.
  • Fan damage or imbalance caused by corrosion or debris.
  • Loose pulleys or belts reducing airflow efficiency.
  • Corroded or missing fasteners and mounts leading to rattling or misalignment.
  • Material fatigue from age or improper maintenance.

Symptoms of failure include higher-than-normal engine temperatures, noise from the cooling fan, or visible cracks and wear on housing parts.

Why Replace Faulty Air Cooling Parts?

A compromised cooling system can lead to overheating, reduced performance, or even engine failure. Replacing worn or damaged components ensures optimal air circulation and temperature regulation, protecting your engine’s reliability and value.

Benefits of replacement include:

  • Restored and efficient airflow across engine components.
  • Consistent operating temperatures and improved engine longevity.
  • Prevention of costly overheating-related damage.
  • Factory-spec fitment and manufacturer-quality materials.

All air cooling parts in this range are designed to meet or exceed exacting engineering standards, ensuring durability, precision, and confidence for both restoration projects and regular maintenance.
