Information
Drive belt idler pulley deflection roller.
This pulley supports and guides the serpentine/accessory belt to maintain proper routing and tension, ensuring it runs smoothly over various engine accessories without slipping or misalignment.
Fits:
Porsche 955 Cayenne 3.2L 2004>> (M02.2Y)
Porsche 957 Cayenne 3.6L 2007 - 2010 (Engine code: 5501)

This idler pulley provides a smooth, correctly aligned surface for the accessory drive belt (serpentine belt) to run over, ensuring proper routing and tension as it drives vital systems such as the alternator, air conditioning compressor, power steering pump, and water pump (as fitted). It keeps belt motion steady and prevents slipping, vibration, or premature wear in the belt system.
A worn, noisy, or seized idler pulley can cause the accessory drive belt to:
• Slip or squeal
• Wear prematurely
• Mis-track off pulley grooves
• Lead to loss of accessory function (e.g., alternator charging, power steering assist, air conditioning)
Replacing a failing pulley restores smooth belt travel, helps reduce noise under the hood, and improves the belt’s service life.
Replace this idler pulley if you notice:
• Squealing or chirping from the front accessory belt area
• Belt wear or fraying
• Vibration or noise from the pulley bearing
• During belt system maintenance or tensioner replacement

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
