Detailed Description

This Dayco 5080805 serpentine belt is a direct-fit main drive belt for select vehicles that use an 8-rib accessory drive layout. It is listed for 2007-2008 Mercedes-Benz GL320, ML320, and R320 main drive applications, plus 1997-2005 Ford E-Series and Excursion applications that are specified without air conditioning. If you are searching for a serpentine belt for a 2000-2005 Ford Excursion main drive or a 1997-2001 Ford E-150 Econoline main drive without A/C, this part number is one to verify against your vehicle build.

This part cross-references Gates K080806 and Bando 8PK2045 for the same application. The Dayco 5080805 is sized for proper belt routing and accessory drive operation where the original belt uses the same 8-rib configuration and length.

Common Problems This Belt Can Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing serpentine belt
• Loss of belt tension or inconsistent pulley engagement
