Detailed Description

Dayco 15298 is an accessory drive belt engineered for select 1985-1986 vehicle applications where exact belt dimensions matter. It cross-references Ford E1TE-8620-AA and General Motors 10036967 for the same application. Compatible vehicle coverage includes 1986 Ford F-150 and 1986 Ford F-250 with alternator and air pump service for 40 and 60 amp alternator setups, plus 1985 Buick Century, 1985 Buick Skylark, 1985 Chevrolet Celebrity, 1985 Chevrolet Citation II, 1985 Oldsmobile Cutlass Ciera, and 1985 Pontiac 6000 in the listed accessory drive positions. The belt’s top cog construction helps it follow pulley paths in accessory drive belt system layouts while maintaining the specified effective length and outside circumference.

• Cracking, glazing, or visible wear on the belt surface
• Poor accessory drive performance at the alternator, air pump, water pump, A/C, or power steering
