The alternator / fan belt transfers drive from the engine pulley to the cooling fan and alternator assembly. On air-cooled Porsche engines, this belt is essential because it powers the fan that moves cooling air across the engine and also drives the alternator to charge the battery and support the vehicle electrical system.

Functions
•  Drives the engine cooling fan
•  Drives the alternator for battery charging
•  Supports correct air-cooled engine temperature control
•  Helps maintain stable electrical system voltage
•  Prevents loss of cooling fan operation caused by belt wear or failure
•  Replaces cracked, glazed, stretched, or worn original belts
•  OE Match replacement for correct fit and reliable belt drive performance

Why Replace This Part?
The alternator / fan belt is exposed to heat, rotation, tension, and engine bay wear. Over time, the belt can crack, stretch, glaze, fray, or lose grip. A worn or failed belt can cause charging problems, battery warning lights, cooling fan failure, overheating risk, belt noise, or complete loss of alternator output. Replacing the belt helps maintain reliable cooling and charging system operation.

When to Replace This Part
•   The belt is cracked, frayed, glazed, loose, or worn
•   There is squealing or slipping from the belt area
•   The battery/charging warning light is illuminated
•   The alternator is not charging correctly
•   The engine cooling fan is not being driven properly
•   The belt has been removed during alternator, fan, or pulley service
•   As part of routine maintenance on Porsche 964 or 993 air-cooled engines
•   As preventative replacement before long journeys or major servicing

Where it fits on the car
This belt fits in the rear engine bay on the engine pulley, alternator, and cooling fan drive assembly. It forms part of the air-cooled engine accessory drive system and is fitted at the fan/alternator housing area.
