Important Installation Notes: This is an elastic stretch belt that is NOT interchangeable with standard serpentine belts of the same size. Vehicles manufactured with stretch belts must be replaced with stretch belts. Installation requires a specialized tool (Dayco Part 93878 recommended) or proper installation technique—do not attempt to install by prying the belt onto pulleys. Detailed installation instructions are provided on the reverse side of the packaging sleeve.

Dayco stretch belts are engineered to OE specifications, providing reliable performance for two, three, and four-point accessory drives designed for self-tensioning operation.
