Detailed Description

This Dayco serpentine belt is specified for the main drive on the Volkswagen Touareg and is sized to match the accessory drive layout used in 2004-2007 applications. The belt’s EPDM compound is selected for heat resistance and long service life, while aramid reinforcement adds tensile strength for demanding engine operation.

Common Problems This Belt Can Address

  • Squealing or chirping from a worn accessory drive belt
  • Cracking, glazing, or fraying on the existing belt surface
  • Loss of proper belt tension or tracking on the pulley system
  • Accessory drive noise caused by belt wear or age
  • Reduced belt grip in high-temperature engine conditions

Installation Notes and Tips

Verify the rib count, effective length, and outside circumference against the removed belt before installation. Inspect pulleys, tensioners, and idlers for wear or misalignment, since those conditions can shorten belt life and affect tracking. For Volkswagen Touareg main drive service, confirm the routing path matches the vehicle’s accessory layout before starting the engine.

Quality Assurance

This belt is manufactured to SAE J1459 and SAE J2432 standards for accessory drive belt performance. Dayco’s EPDM and aramid-reinforced construction supports dependable service in the specified temperature range and under continuous engine accessory loading.
