Information
Alternator belt, Narrow V-belt.
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

Information
Alternator belt, Belt size: 9.5 x 725.
This OE Match alternator belt is a replacement engine drive belt for Porsche 911 models from 1974 to 1979. It is designed to match the original-style fitment and function. This replacement drive belt helps power the alternator and cooling fan assembly, supporting reliable battery charging and engine cooling system operation.
Fits:
Porsche 911 Turbo/SC 1974 - 1979 (Please choose by size)
Diagram ref no 12
The alternator belt transfers rotational drive from the engine pulley to the alternator and fan assembly. This allows the alternator to generate electrical power for the vehicle while also helping drive the engine cooling fan. A correctly fitted and tensioned belt is essential for reliable charging, cooling airflow, and overall engine operation.
Functions
• Replaces the alternator drive belt
• Drives the alternator and cooling fan assembly
• Supports correct battery charging
• Helps maintain air-cooled engine cooling airflow
• Replaces cracked, glazed, stretched, frayed, noisy, or slipping belts
• Suitable for routine servicing and preventative maintenance
• OE Match replacement for classic Porsche 911 engine service.
Why Replace This Part?
Alternator belts wear over time due to heat, engine vibration, pulley contact, age, and tension changes. A worn belt can crack, glaze, stretch, fray, squeal, slip, or fail completely. If the belt fails, the alternator may stop charging and the cooling fan may stop operating correctly, which can lead to warning lights, battery issues, overheating risk, or vehicle breakdown. Replacing the belt helps maintain dependable charging and cooling system performance.
When to Replace This Part
• The alternator belt is cracked, glazed, frayed, loose, or worn
• Belt squeal or chirping is heard during start-up or acceleration
• The battery warning light appears
• Charging system output is low or inconsistent
• Cooling fan drive is being inspected or serviced
• Alternator, fan, pulleys, or related hardware are being repaired
• Preventative belt replacement is being carried out during scheduled maintenance.
Where it fits on the car
This belt fits on the alternator and cooling fan drive system on Porsche 911 models from 1974 to 1979. It runs between the relevant engine pulley and alternator / fan pulley according to the factory belt routing.
