Produced to OE-style specifications, this drive belt is engineered specifically for Porsche models equipped with the factory-fitted York air conditioning compressor, providing the correct length and profile for dependable power transmission. Manufactured from high-quality, reinforced rubber compounds with high-strength tensile cords, it offers excellent resistance to heat, wear, and stretching, ensuring reliable performance for maintenance, repairs, and restoration projects.
Fits:
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50

The air conditioning belt transfers engine power to the factory York compressor, enabling efficient operation of the air conditioning system. Over time, continual heat cycles, age, and normal use can cause the belt to harden, crack, glaze, or stretch, reducing drive efficiency and increasing the risk of belt slip or failure. Replacing a worn belt restores dependable compressor operation and helps maintain effective air conditioning performance, making this OE Match component an ideal choice for Porsche maintenance, repairs, and restoration projects.
What This Product Does:
- Transfers engine power to the factory York air conditioning compressor.
- Ensures reliable compressor operation.
- Maintains correct belt tension and drive efficiency.
- Helps provide consistent air conditioning performance.
- Reduces the risk of belt slip and drive loss.
- Replaces worn, stretched, cracked, or glazed drive belts.
- Provides an OE-style fit for straightforward installation.
Symptoms Of Wear Or Failure:
- Cracked, frayed, or glazed belt surfaces.
- Belt squeal during start-up or compressor engagement.
- Air conditioning operating intermittently or inefficiently.
- Belt slipping or poor belt tension.Visible stretching or deterioration.
- Rubber debris around the pulleys.Complete belt failure preventing compressor operation.
Why Replacement Matters:
- The air conditioning belt is essential for transmitting engine power to the factory York compressor, allowing the air conditioning system to function efficiently. As the belt ages, it can lose tension, crack, or deteriorate, reducing compressor performance and increasing the risk of unexpected failure. A failed belt will prevent the compressor from operating and may also leave damaged belt material within the engine compartment.
- Replacing a worn drive belt restores reliable compressor operation, maintains correct belt tension, and helps ensure consistent air conditioning performance while reducing the likelihood of roadside belt failure. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Air Conditioning Belt for Factory York Compressor delivers reliable fit, performance, and durability for Porsche maintenance, repairs, and restoration projects.

Belt size: 10 x 713 mm
The V-belt runs between the crankshaft pulley and the alternator/fan pulley. It’s the primary mechanical link that spins the alternator to charge the battery and, on air-cooled 911s and 914-6 models, turns the engine cooling fan.
Fits:
Porsche 911 1965 - 1973
Porsche 911 Turbo 1976 >>
Porsche 911 SC 1974 - 1979 (Check Size of your Belt)
Porsche 911 SC 1980 - 1983
Porsche 911 3.2L 1984 - 1989
Porsche 914 1970 - 1976
Please note: Always confirm against the belt size currently fitted and pulley setup before ordering.
Why Replacement Matters - With age and mileage, belts:
• Crack, glaze, or harden, reducing grip
• Stretch, making correct tension impossible
• Begin to slip, causing charging issues and, on air-cooled engines, reduced cooling fan speed
A slipping or failing belt can lead to battery discharge, warning lights, overheating, or being stranded. Fitting a fresh belt restores reliable alternator and fan drive, protecting both the engine and electrical system.
When to Replace - Consider replacing the alternator belt if:
• You see cracks, fraying, glazing, or missing chunks in the belt rubber
• The belt squeals on startup or under load
• The belt has stretched and can’t be tensioned correctly
• You’re doing routine service on a classic 911 / 914-6 or preparing for a long trip
• The car is undergoing engine-out work or restoration
