Detailed Description

Dayco 5040362 is a serpentine belt for accessory drive belt system components, sized for compact 4-rib applications. Its EPDM rubber compound helps resist heat-related wear, while aramid reinforcement adds strength for demanding accessory loads. The belt’s straight rib profile and deep rib construction support consistent contact with the pulley grooves, which is important in systems that drive the alternator, water pump, power steering, or air conditioning/idler components.

This part cross-references Bando 4PK920 for the same application.
