Product Details

Gates Micro-V belts are engineered to follow OE dimensions and material standards, helping maintain proper drive alignment and accessory operation. This K080645 serpentine belt uses an EPDM construction with polyester cord reinforcement and an 8-rib profile, making it a direct replacement choice for vehicles that require the listed belt length and section. If you are servicing a 1989-1993 Dodge D250, D350, W250, or W350 without A.C., this belt matches the documented application data for those trucks. This part cross-references Dayco 5080645 for the same application.

What This Belt Helps Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing serpentine belt
• Loss of proper belt tension due to age-related stretch
• Accessory drive noise caused by an incorrect belt length or profile
• Reduced belt tracking on the pulley system
